Answers
Answer:
The correct answer is : C. 1 - oxygen ; 2 - carbon dioxide.
Explanation:
The given picture shows the occurrence of photosynthesis and cellular respiration in the plant and animal, respectively. Both the processes form a part of the Carbon Cycle.During photosynthesis, the plant utilises the carbon dioxide, obtained from the air, and water, obtained from the soil, along with light energy, to produce its metabolic product, glucose and by-product, oxygen.During cellular respiration, the animal utilises the oxygen released by the plants for oxidising its food and obtaining energy and release carbon dioxide as by-product which is again taken up by the plants for photosynthesis.This is the way by the carbon cycles in the biosphere.

An organism has three different versions of Gene Tyx – version a, b and c. Determine the inheritance pattern of this trait. Then list below all of the different genotypes that an organism with this gene could have.
Answers
Answer:
The inheritance pattern of these traits will be independent. However, it will depend on the factor that which trait is dominant or recessive. It might also show incomplete dominance.
The different genotypes that organisms of this population might have are aa, ab, ac, bb, bc , cc. If neither of the alleles are completely dominant over the other, then incomplete dominance might exist for such genes.
The inheritance unit of hereditary is called a gene. They get passed on from the parent to their generation through reproduction.
The genotypes this group can exhibit are aa, ab, ac, bb, bc, cc.

After buying a new house by the lake, the Harrison's decided to cut down the trees and bushes that were blocking
their view. This left an open area with no vegetation between the house and the lake. What type of pollution is
demonstrated in this real world example?
Toxic
Sediment
Nutrignt

Answers
Final answer:
The Harrisons' actions of removing vegetation by the lake lead to sediment pollution, which can carry various pollutants into the water and disrupt the ecosystem. Option B
Explanation:
The real-world example of the Harrison's cutting down vegetation and leaving an open area between their house and the lake is an instance of sediment pollution. When vegetation that stabilizes soil is removed, there is an increased risk of erosion. Soil particles, also known as sediments, can be swept into the lake, particularly during rain events. This sediment can cloud the water, reducing sunlight for aquatic plants, and can carry other pollutants such as pesticides and bacteria into the lake. This process disrupts ecosystems and can lead to negative consequences such as turbidity and eutrophication.
What do the c cells of a thyroid gland produce
Answers
Calcitonin is a hormone produced by the c cells of the Thyroid gland.
Explanation:
The c cells present in the thyroid are otherwise called Parafollicular cells. The primary function of c cells is to secrete Calcitonin (a protein hormone) which has a minor role in calcium regulation.Calcitonin decreases the parathyroid hormone (PTH), by lowering blood calcium level by suppressing osteoclast activity of bones and increases of calcium Which is excreted along with the urine.The C cells are found next to the Thyroid follicles and present in the connective tissue.
The C cells or parafollicular cells of the thyroid gland produce a hormone known as calcitonin, which plays a crucial role in the regulation of calcium levels in the body.
Explanation:
The C cells, also known as parafollicular cells, of the thyroid gland produce a hormone known as calcitonin. Calcitonin is an important hormone for the regulation of calcium levels in the human body. It works in tandem with the parathyroid hormone to decrease high calcium levels in the blood. When the blood calcium level is high, calcitonin is secreted. This hormone then stimulates the transfer of calcium from the blood into the bones, thus reducing the calcium level in the blood.

Explanation:
Does my dog like me?" - Nonscientific. Are bats blind? - Scientific. What do fish eat? - Scientific. Do unicorns really exist? - Nonscientific. Can bees communicate by doing a special dance? - Scientific.
The answers to whether each question is scientific or nonscientific are as follows:
1. ""Does my dog like me?"" - Nonscientific. This question is about a subjective experience and personal feelings, which cannot be empirically tested or observed.
2. ""Are bats blind?"" - Scientific. This question can be answered through biological research and empirical observation. Bats are not blind; many species use echolocation to navigate and can see.
3. ""What do fish eat?"" - Scientific. This question can be answered through biological and ecological research. Different species of fish have different diets that can be studied and documented.
4. ""Do unicorns really exist?"" - Nonscientific. Unicorns are mythical creatures, and their existence cannot be tested or observed in the natural world.
5. ""Can bees communicate by doing a special dance?"" - Scientific. This question can be answered through entomological research. It is well-documented that bees, particularly honeybees, perform a waggle dance to communicate the location of food sources to other members of their hive.
Scientific questions are those that can be answered through empirical research, observation, and experimentation. They are based on phenomena that can be measured and tested. Nonscientific questions, on the other hand, often involve subjective experiences, personal beliefs, or hypothetical entities that cannot be empirically tested or observed.

A scientist injected a drug into a mouse that inhibits the formation of mRNA in either the sperm or egg cells.
What could be the result of this alteration?
Answers
Answer:
The mouse will not be able to form sperm or egg or abnormal sperms or egg will be formed.
Explanation:
For the synthesis of proteins, the DNA is transcribed and an mRNA is formed. This mRNA is translated by the ribosomes and a protein is formed. If mRNA is not formed, then the protein will not be able to form.
If the formation of mRNA is inhibited for the sperm or egg cells they will either not form the right kind of sperm or egg cells or will not produce them at all depending on the mRNA that is being inhibited from the formation.

Scientists would have to have the fossils of all organisms in a certain
species to be able to tell if punctuated equilibrium occurred.
Scientists can tell that punctuated equilibrium occurred if they examine
the fossil record and see that one organism rapidly evolved different
characteristics
Answers
Answer:
The answer is: Scientists can tell that punctuated equilibrium occurred if they examine the fossil record and see that one organism rapidly evolved different characteristics.
Explanation:
The theory regarding "punctuated equilibrium" followed after Darwin's Theory of Evolution. According to Darwin, species evolved over time. However, evidence supporting it is lacking when it comes to fossil record. He thought that this was because the fossils were incomplete.
Darwin's idea was contradicted by evolutionary scientists, named Stephen Gould and Niles Eldrege. According to them, species change after millions of years (this phase is called "punctuated") and their change is sudden (and not gradual). This sudden change is very rapid, thus causing a fewer number of fossils being left behind. Most species who undergo speciation, occur in a different geographic location, thus leaving only a few number of fossils.
So, this explains the answer.

Refer to figure 10.13. Which photos (A-I) best illustrate the methods of fossilization or fossil evidence listed below
Answers
Answer:
Permineralization:
A. Trilobite fossil
F. Trilobite fossil
B. Fossilized wood
Cast:
G. Fossil dung
Carbonization:
C. Fossil bee
I. Fossil fish
Impression:
D. Fossil brachiopods
Amber:
H. Fossil spider
Indirect impression:
E. Dinosaur track
G. Fossil dung
Explanation:
Permineralization:
The most common process of fossilization in which the remains of the organism, particularly, the internal cavities are replaced by the deposition of minerals carried by water or sediment.
Cast:
Casts are formed when the actual remains and bones of the organism are dissolved, creating a depression or a mould that gradually fills with sediments to form a cast of the exact shape of the original.
Carbonization:
The fossilization process in which only the residual carbon of the living organism remains leaving behind a thin carbon layer.
Impression:
Fossilization that involves the preservation of the prints or impressions of animals and plants when the print is made in silt or mud. This mud or silt hardens to rock.
Amber:
Amber is living organism preserved in fossilized tree resin.
Indirect Impression:
Indirect impressions are two dimensional imprints that do not contain any organic material from the organism itself but give a clue of its existence and biological activity. Footprints, tracks and excrement is fossilized in this manner.
The question focuses on matching photos to different methods of fossilization, requiring reference to textbook figures and flowcharts. The answer would involve examining photo characteristics and comparing them with textbook descriptions of fossil preservation processes.
Explanation:The student's question pertains to identifying methods of fossilization and analyzing fossil evidence, based on images from a textbook. The question requires matching specific photos illustrating different fossilization processes to a list of such methods. To address such a question, one would typically refer to the figures provided in the textbook, which likely include visual examples of petrification, mold and cast fossils, amber preservation, permineralization, and other types of fossil evidence. Utilizing the flowcharts and exercises mentioned, such as Figure 6.10 and Exercise 6.2, would aid in understanding the mode of preservation. Additionally, figures showing the evolutionary progression of species through fossil records, such as whales and horses, provide context for understanding the diversity and history of life on Earth as evidenced by fossils.
When helping a student with this type of inquiry, a tutor would guide them to look at the characteristics of each photo, such as whether there is presence of original biologic material, positive and negative relief, and mineral composition, and compare these with the types of fossilization processes described in the textbook. Being able to identify such features enables one to determine fossil evidence and likely methods of fossilization. Critical thinking may also be applied in assessing whether certain fossils suggest organisms are now extinct, by identifying unique features not found in modern-day species.
