Final answer:
Fungi respond to light, touch, water presence, and gravity, showcasing their adaptability to environmental conditions. Although they do not perform photosynthesis, their responses to environmental stimuli ensure survival and growth in diverse habitats.
Explanation:
How fungi respond to environmental stimuli is a fascinating aspect of their biology, showing both similarities and differences with plants. Here are the accurate statements about fungi's response to environmental stimuli:
Fungi, like plants, respond to light.Both fungi and plants respond to touch.Fungi hyphae grow toward water.Both plants and fungi grow against gravity.Contrary to a common misconception, fungi do respond to light, even though they are not autotrophs. This phototropic response does not stem from a need to photosynthesize but may influence the direction of growth or the development of fruiting bodies. Similarly, fungi exhibit hydrotropism, where their hyphae grow towards sources of water, and they can respond to touch and gravity, demonstrating a complex interaction with their environment. Unlike plants, fungi do not carry out photosynthesis because they lack chlorophyll; they obtain nutrients through heterotrophic means, absorbing organic compounds from their surroundings.

Which of the following statements about cellulose is FALSE? Microtubules are directly attached to the outside surface of the plasma membrane to form tracks that help orient the cellulose polymers Cellulose is synthesized on the outside of the cell. An array of microtubules guides the cellulose synthase complex as it moves in the membrane Cellulose synthase enzyme complexes are integral membrane proteins
Answer:
Option A is false, the remaining statements regarding cellulose are correct
"Microtubules are directly attached to the outside surface of the plasma membrane to form tracks that help orient the cellulose polymers"
Explanation:
Cellulose is specific to plant cells walls only, animal cells do not contain cellulose. It is produced at the membrane of the cell. The microtubules are actually attached to the inside of the plasma membrane and it helps to orient the cellulose polymers that way. It provides vital structural support to the plant.

A rare genetic disease which is due to a recessive allele (a) and that is lethal when homozygous, occurs within a specific population at a frequency of one in a hundred thousand. In other words, one out of a hundred thousand individuals are homozygous recessive with the disease. How many individuals in a town with a population of 20,000 can be expected to carry this allele?
Answer:
40 individuals
Explanation:
The homozygous recessive percentage is equal to q2.
Recessive genotype frequency, q 2 is 1/1000000 = 0.000001
therefore, q = [tex]\sqrt{q2}[/tex] = [tex]\sqrt{0.000001 }[/tex] = 0.001 = allele "a" frequency
and p + q = 1, thus, p = 1 – q = 1 – 0.001 = 0.999
thus, the frequency of allele a = q = 0.001 and the frequency of allele A = p = 0.999
Carriers are heterozygous and are equal to 2pq.
So, 2pq = 2 x 0.999 x 0.001 x 20,000 = 39.96 (round of to 40)
Hence, 40 individuals will be expected to carry the recessive allele.
A botanist is conducting a two-factor experiment on seed germination. One factor is temperature, with two levels: cold storage and ambient temperature storage. The other factor is gibberelin treatment, which occurs at four different concentrations. Our botanist attempts this experiment on the cheap, with only one seed per treatment group (hey, maybe it's a coconut). If the ANOVA includes a test for the two-way interaction, how many degrees of freedom will our hero have for error? 3 0 4 7 1
Answer:
67Explanation:
In a two-factor experiment with two levels of one factor and four levels of another factor, where each combination of factors is represented by one observation (as is the case with the botanist's seed germination experiment), the degrees of freedom for error would be zero.
Explanation:In a two-factor experiment, the degrees of freedom for error are calculated as (total number of observations - total number of treatments). Here we have 2 levels of temperature and 4 levels of gibberelin treatment. So, there are 2*4=8 total treatments. In this case, each treatment being tried on one seed means there are also 8 total observations. Thus, when the botanist attempts the experiment, the degrees of freedom for error would be (8-8)=0.

Fossils show that there was a global heatwave about 56 million years ago. What were 3 results of that heat wave? PLEASE HELP ME!!!
Answer:
The results of the heat wave are the rising of sea levels, the oceans became more acidic, and species disappeared
Explanation:
About 56 million years ago, heat wave occurs due to the increase in the concentration of greenhouse gases which are present in the atmosphere. We know that greenhouse gases such as carbon-dioxide etc were the main cause of global warming. Due to this warming, many temperature sensitive species die, melting of ice occurs which increases the sea level and carbon-dioxide deposition occurs in the ocean water which make the water more acidic and the life of marine animals will be adversely affected.

Some autoimmune diseases show a positive correlation with dramatically decreased expression of histone deacetylase (HDAC9, an enzyme that removes acetyl groups from histones). Why would the decreased expression of HDAC9 cause immune cells to produce inflammatory genes at inappropriate times?
Answer:
The positive charge of the histone proteins get reduced due to the process of histone acetylation, thus making the wrapping of DNA around the histones less tightened. The loose connected DNA afterward associates with the transcription factors for the articulation of the genes situated in that area.
Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again. In case, when less expression of histone deacetylase enzyme occurs, the process of deacetylation fails to take place. This indicates that within an immune cell, at the time of infection, the inflammatory gene, which was made available does not get re-wrapped firmly around the histones.
A child with the genes for PKU (a recessive disorder that leads to brain damage because proteins aren't digested properly) is raised to adulthood under a strict low-protein diet that prevents the gene from being activated. He lives a normal life and eventually becomes a father. As a genetic counselor, explain whether the fact that his gene is inactive affects the probability his future children might inherit the PKU allele. Be complete. Explain the reasoning you used to reach your conclusion.
Answer:
Even if the gene is inactive, you can inherit the gene from your children.
Explanation:
Genetic inheritance is determined by the patterns that are dominant or recessive, not with the activation or not of the gene that you already possess, so depending on whether your partner is a carrier of the gene, there will be a greater probability of inheriting it from your children, even if your partner is a non-carrier of the gene none of the descendants inherits the condition, but they are all carriers, if their partner is a carrier but does not affect it, there is a 50% probability that one descendant is affected, and the rest are carriers but not inherited the condition, if their partner is a carrier, there is a 25% probability that a descendant is affected, a 50% probability that they are carriers but without manifesting the condition, and a 25% probability of not having any recessive allele.
In this case, the inactive gene of man affects the probability his future children might inherit the PKU allele - remain same or 1.
PKU is a latent ailment recessive disorder that leads to brain damage because proteins aren't digested properly, and the man in this issue is two alleles of the recessive allele.
he carries on with a typical life by staying away from protein-rich sustenance
he conveys those passive alleles in his genome when he creates gametes with passive alleles.
on the off chance that P is overwhelming ordinary allele and p is latent allele.
man is pp and gametes he creates are p so the majority of his descendants will have this allele p
so the likelihood that he will acquire this allele p to his youngsters is 1 since the majority of his gametes contains p allele.
The probability of inheritance of that gene remains the same
Thus, In this case, inactive gene of man affects the probability his future children might inherit the PKU allele - remain same or 1.

Which of the following is a monomer of DNA?
A) Protein
B) Oil
C) Nucleotides
Answer:
C) Nucleotides
Explanation:
Nucleotides are the monomers, or building blocks, of DNA. Therefore, option (C) is correct.
What are nucleotides?They are composed of three main components: a sugar molecule (deoxyribose in the case of DNA), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). These nucleotides join together through phosphodiester bonds to form a long chain, resulting in the formation of the DNA molecule.
Each nucleotide in the DNA chain pairs with a complementary nucleotide from the opposing DNA strand through hydrogen bonding, creating the double helix structure of DNA. Therefore, nucleotides are the fundamental units that make up the structure of DNA and carry the genetic information in living organisms.

The correct answer of 47 is option c, that is, G0 phase.
The correct answer of 48 is option e, that is, Avery, McCarty and Macleod.
Explanation:
46. Erwin Chargaff with the help of an experiment demonstrated that the amount of adenine present within the DNA is always equivalent to the amount of thymine present, similarly, guanine is always found in equal number to cytosine. He also demonstrated that pairing is always done between pyrimidines and purines within the DNA.
47. It is in the G0 stage, also known as the quiescent stage, where a human cell is found in the non-proliferating phase. It is also considered as the resting stage of the cell cycle in which cell gathers enough of the substances for its nourishment. When the cell moves into the G0 stage of the cell cycle, then the cell either goes to further stages of the cycle when needed or goes through the process of differentiation.
48. To prove that DNA works as a genetic substance, the Griffith experiment was further used by Avery, McCarthy, and Macloed. The experiment was again performed on a biochemical basis. In the experiment, distinct constituents of the bacterial cell were digested with the assistance of digestive enzymes, and in the process, it was found that when digestion of DNA was done, the process of transformation failed to take place. The performed experiment was also called the biochemical assay of transformation.

Which of the following correctly describes an interaction that occurs between two body systems of a rabbit that helps the rabbit outrun a pursuing coyote?
Your answer:
A. The skeletal system releases additional calcium, and the circulatory system retains more sodium in the blood to provide muscles with ions for contraction.
B. The digestive system increases the rate of digestion, and the excretory system ceases to provide tissues with more nutrients
C. The respiratory system increases the breathing rate, and the circulatory system increases blood pressure to provide tissues with more oxygen.
D. The endocrine system releases hormones that prepare the immune system to deal with possible injuries
Answer: C. The respiratory system increases the breathing rate, and the circulatory system increases blood pressure to provide tissues with more oxygen.
Explanation:
Oxygen is a key component in respiration which supplies the body with energy. To be more precise, oxygen is needed for Aerobic Respiration which is the process by which the body turns fats and sugars into fuel using oxygen.
This fuel/energy is then used by cells to engage in activity.
When the Rabbit tries to outrun the coyote, the Respiratory System increases the breathing rate to allow more oxygen in. This oxygen is supplied to cells by blood so the Circulatory system uses the oxygen to increase blood pressure to get blood moving faster so that it can get more oxygen to the cells to enable them produce more energy needed to outrun the Coyote.
The vertebrates are highly organized organisms, which have developed circulatory, respiratory, neural, and excretory systems.
The rabbit can outrun a coyote due to an increase in the breathing rate and blood pressure by the circulatory system.
Functions of the respiratory and circulatory system are:
The respiratory system is a dense network of organs and tissues, which help organisms breathe. The respiratory center is in the brain, where the basic rhythm of breathing is set. The circulatory system is involved in the circulation of blood, gases, and nutrients throughout the body. The cardiovascular center receives the changes in pH and stretch, which alter the heart rate and stroke volume to increase the blood pressure.
Thus, the correct answer is Option C.

C. lungs, nose, trachea, and bronchial tubes
The Respiratory System primarily consists of the lungs, nose, trachea, and bronchial tubes. These components work together to facilitate the exchange of gases between the body and the external environment.
The nose and nasal passages act as the entry point for air, filtering and humidifying it before it reaches the lungs. From the nose, air moves into the trachea, a tube reinforced with cartilage rings that prevents collapse during breathing. The trachea branches into the bronchial tubes, which further divide into smaller tubes that lead to the alveoli, the tiny air sacs in the lungs where gas exchange occurs.
Oxygen from the inhaled air diffuses across the walls of the alveoli and enters the bloodstream, while carbon dioxide, a waste product of cellular respiration, moves from the blood into the alveoli to be exhaled. This process ensures that cells receive the oxygen they need and that waste carbon dioxide is removed from the body.
The question is:
The Respiratory System includes:
A. heart, veins, and arteries
B. stomach, trachea, intestines
C. lungs, nose, trachea, and bronchial tubes
D. lungs, heart, stomach

Trees are the lungs of the planet earth which helps in cleaning the environment and provide habitat to millions of organisms. Trees absorb carbon-dioxide which is responsible for pollution and global warming and releasing oxygen which is necessary for the survival of living organisms. If these trees are removed, the habitat of many living organism will be destroyed and also increase occurs in the pollution and global warming of the earth atmosphere.
Answer: Trees are producers they use photosynthesis to create energy for food chains.
Explanation: Food chains are an exchange of energy that starts with producers and in this case the trees. Without the trees, there wouldn't be any food and the cycle would collapse.
Which particle has a high rate of deposition?
Answer:
A particle with jagged, rough ends has a high rate of deposition.
Explanation:
When erosion takes place, the particles of rocks move from one place to another and then they get settled on the new place. Those particles which have round shaped ends cannot settle quickly because they can be easily pushed by air and again moved but particles having rough ends get stuck in the soil or surface of earth and they are settled quickly.
The particle with a high rate of deposition could either be an alpha particle, due to its interaction with high electron densities like in lead, resulting in quick loss of kinetic energy, or sediment particles in water bodies, due to gravitational pull and terminal velocity.
Explanation:The concept of 'deposition' can mean different things in different contexts. In the context of the physical sciences, it is usually related to the process by which a substance changes from a gas phase to a solid phase without passing through an intermediate liquid phase - this process is often observed in alpha particles. However, when it comes to movement and settlement of particles, sediment in a body of water might come to mind which has a slow deposition rate as the terminal velocity is quite low.
Depending on the context, the particle with a high deposition rate can either be an alpha particle or sediment particles in a body of water. Alpha particles have a high rate of deposition due to their interaction with high electron densities, such as in lead, where they lose their kinetic energy quickly and deposit on surfaces. On the other hand, sediment in a water body can have a higher rate of deposition due to gravitational pull and the terminal velocity at which they're able to move. This has been studied extensively in places like particle colliders, where subatomic particles are made to move at high speeds, including the alpha particle.

Which of the following conclusions can be drawn from the case study of Phineas Gage’s accident, which led to brain injury?
Phineas Gage's case suggests that the prefrontal cortex significantly contributes to an individual's personality. His recovery implies the concept of neuroplasticity, or the brain's capacity to adapt and change. However, the interpretations of Gage's personality changes might have been exaggerated due to a lack of comprehensive data.
Explanation:Based on the case study of Phineas Gage, we can draw the conclusion that the prefrontal cortex plays a crucial role in determining personality. Gage's personality significantly changed after an iron rod penetrated this specific region of his brain. This shift in behavior confirmed the idea of localization, the belief that certain functions are associated with specific regions of the brain.
Additionally, Gage's apparent return to functionality (by becoming a stagecoach driver after the accident) is associated with the concept of neuroplasticity. This refers to the brain's ability to adapt or alter in response to experiences or injuries. In Gage's case, even following such a traumatic incident, his brain managed some degree of recovery.
It is worth noting that the accounts of Gage's behavioral changes could have been overemphasized or skewed due to the contemporaneous scientific debate on localization and the lack of extensive information about Gage.
