It's C Fungi cannot make their own food

The right option is; C)

Fungi cannot make their own food is the statement that BEST describes why mycelium, constructed of hyphae, are necessary for fungi survival.

Mycelium are the vegetative part of any fungus, consisting of a mass of branching, threadlike hyphae, usually found under the ground or inside the substrate on which the fungi are growing. The large masses of hyphae within the mycelium perform an essential role by obtaining nutrients from the organic substrates in which the fungi live or from beneath the soil to support fungi growth and its survival. This is because fungi do not have chlorophyll and cannot manufacture their own food.

Answer:

The process of photosynthesis can be defined as the process by which the the plants make food.

This food is produced when a chemical reaction takes place in the leaves where the carbon dioxide, water in the presence of sunlight is converted into glucose and oxygen.

This glucose and oxygen is used in the process of cellular respiration where the glucose is broken down ad the energy obtained is stored in the form of adenosine tri phosphate in the presence of oxygen.

Some frogs are slimy because they are covered in a mucous coating. This coating helps them keep their skin moist which helps them breathe through their skin. The mucous often contains other chemicals, like antibacterial or anti fungals to help protect the frog.

I hope this helps you

Amphibians are slimy due to their permeable skin and mucus glands, which help in respiration, moisture retention, and protection against predators. This slimy layer is essential for amphibians' survival in their wet habitats and plays a crucial role in their sensitivity to environmental changes. The mucus can also contain toxins to deter threats.

Amphibians, such as frogs, toads, salamanders, and newts, are known for their slimy appearance, which is a result of their unique skin properties. Their skin is permeable and contains mucus glands that secrete a moist layer of mucus. This moist layer is crucial for their survival as it helps in cutaneous respiration, allowing them to absorb oxygen and release carbon dioxide directly through their skin. Additionally, the mucus serves to keep their skin moist, protecting them from dehydration while also facilitating easier movement in water.

Another vital role of the mucus is to protect amphibians from predators. In some species, the mucus contains toxins which can deter or harm potential threats. The unique skin of amphibians also means they are especially sensitive to environmental changes and pollution, making them important indicators of ecosystem health.

Living both on land and in water, amphibians have adapted to their environments with features like a lightweight skull and calcified bones to support movement and respiration in both mediums. Their skin's capacity to absorb water and gases directly is why amphibians are often found in moist environments and why they are at risk in dry or polluted conditions.

The frequency of the heterozygous rabbits is 0.65. The frequency of the B allele is 0.675. The frequency of the b allele is 0.325.

a. The frequency of heterozygous rabbits can be calculated by subtracting the frequency of the homozygous dominant genotype (BB) from 1. Since the frequency of the BB genotype is 0.35, the frequency of heterozygous rabbits is 1 - 0.35 = 0.65.

b. The frequency of the B allele can be calculated by adding half of the frequency of the heterozygous genotype (Bb) to the frequency of the homozygous dominant genotype (BB). Since the frequency of the BB genotype is 0.35 and the frequency of the Bb genotype is half of the frequency of heterozygous rabbits (0.65/2 = 0.325), the frequency of the B allele is 0.35 + 0.325 = 0.675.

c. The frequency of the b allele can be calculated by subtracting the frequency of the B allele from 1. Since the frequency of the B allele is 0.675, the frequency of the b allele is 1 - 0.675 = 0.325.

The Hardy-Weinberg equilibrium and its principals can be used to answer all the genetics-related questions about rabbits, lizards, humans and more. The frequency of genotypes can be calculated by dividing the population of each genotype by the total population size. To determine if populations are in Hardy-Weinberg equilibrium, we need to compare observed frequencies with predicted frequencies and see if they match.

In answering your questions, it is crucial to understand the Hardy-Weinberg equilibrium and its equation p^2 + 2pq + q^2 = 1.

For your first questions, without further information, it is impossible to accurately determine the frequency of heterozygous rabbits (Bb) or the frequencies of the alleles (B and b). However, you can generally calculate the frequency of the b allele from the frequency of bb rabbits and the B allele frequency from the overall allele total.

For the lizard question, the frequency of genotypes would be calculated by dividing the number of each genotype by the total population size. The Hardy-Weinberg equilibrium isn't necessarily maintained because drift and selection could have occurred in the population. We would need to analyze if the frequencies of the genotypes match the predicted frequencies based on the allele frequencies: p^2, 2pq, and q^2.

In relation to the human blood type question, the same calculation applies as for the lizard, by dividing the population of each genotype by the total population size. However, in predicting the new generation under the Hardy-Weinberg equilibrium, we would need to make some assumptions like infinitely large population size, random mating, no mutation, no migration, and no selection, which are not likely to be true in a real population.

For the birds, it seems that you might have gotten the dominance relationships reversed. In this case the frequency of each allele could be determined by finding the frequency of the recessive phenotype (assuming it is homozygous) then taking the square root (getting q), and p = 1 - q. However, the frequencies of the genotypes isn't straightforward because dominance doesn't tell you anything about the heterozygotes.

For your final question, if 9% of an African population is born with the severe form of sickle-cell anemia (ss), this means that q^2 = 0.09 and q = 0.3. Using this, p can be solved as 1 - q = 0.7, and 2pq gives the estimated proportion of heterozygous individuals in the population.

Explanation:

Final answer:

The seven characteristics of life are order, sensitivity, reproduction, growth, regulation, energy processing, and evolution.

Explanation:

The seven characteristics of life are order, sensitivity or response to the environment, reproduction, growth and development, regulation/homeostasis, energy processing, and evolution.

Order refers to the organization of living things, such as the arrangement of cells or body parts. Sensitivity allows organisms to respond to stimuli in their environment. Reproduction is the ability to produce offspring.

Growth and development involve an increase in size and change over time. Regulation and homeostasis refer to the ability to maintain a stable internal environment. Energy processing involves the use of energy to carry out life processes. Evolution is the change in inherited characteristics over successive generations.

Protein can be categorized into two types: complete and incomplete proteins.

Proteins are made up of smaller units, called amino acids.

Complete proteins contain all of the amino acids your body needs and include meat, fish, poultry, dairy, and soy products.

The correct answer is C. Insert the gene into bacteria.

To produce a protein from a gene, one common method is to use recombinant DNA technology. In this process, the isolated gene responsible for the protein of interest is inserted into a host organism, often bacteria or yeast, which can then produce the protein.

Here's how it works:

1. **Isolate the gene:** The scientist has already isolated the gene responsible for the protein found in chicken liver.

2. **Insert the gene into bacteria:** The isolated gene is inserted into a bacterial host's DNA. This is typically done using a plasmid, a small, circular piece of DNA that can be easily manipulated and introduced into bacteria.

3. **Expression:** The bacteria, now containing the gene of interest, can be cultured and induced to express the protein. This is often achieved by adding certain chemicals or changing the growth conditions in a way that triggers the bacterial cells to produce the protein.

4. **Protein production:** As the bacterial cells grow and divide, they produce the protein encoded by the inserted gene. This protein can then be harvested and purified for further study or use.

Options A and B ("use reverse transcriptase on the gene" and "mix gene with a cDNA probe") are not the standard methods for protein production. Reverse transcriptase is used to convert RNA into complementary DNA (cDNA) and is typically employed in the generation of cDNA libraries for studying gene expression, while cDNA probes are often used in hybridization experiments to detect the presence of specific RNA molecules. Option D ("Find all the mRNA produced by the liver") is related to studying gene expression but doesn't directly produce the protein of interest.

Answer:

kinetic energy

Explanation:

When the molecules or atoms of a substance have high kinetic energy, the atoms/molecules move rapidly and collide frequently and harder. Most collisions are inelastic meaning that some of the energy in the collision is lost mostly as heat. This is why increasing the kinetic energy of a substance’ atoms/molecules causes the temperatures of the substance to rise. This is how heating by magnetic induction works.

The Answer Is Heat Brainliest PLZ

Answer:

Heat

Explanation:

Heat is a form of energy (thermal energy) in transition, which is transferred by non-mechanical means due to a temperature difference.

Heat always flows from the higher temperature system to the lower temperature system.

Its nature is transitory, so it makes no sense to speak of heat stored in a system, but of heat flowing from one system or substance to another given a temperature difference.

If there is no difference in temperature, no heat will flow between systems or substances.

Photosynthetic organisms take light energy and use it to make their own "food". In this process they use carbon dioxide and light to make sugars and oxygen. This is great for other animals that utilize this oxygen and eat the plants for food.

Photosynthesis benefits all living things because chloroplasts absorb sunlight. In photosynthesis, water (H2O) and carbon dioxide (CO2) both reacts to form glucose (C6H12O6) that is actually food for the plants. Therefore, all living organisms get benefits by eating a similar type of food that gives energy to them. All animals and even human gets much of minerals and vitamins from plants when it is consumed.

The Calvin cycle involves three stages: fixation, which incorporates CO2 into an organic molecule; reduction, which reduces the organic molecule using NADPH; and regeneration, wherein the RuBP molecule is regenerated. The cycle converts atmospheric CO2 into carbohydrates, and must complete several turns to produce glucose.

The Calvin cycle, part of the photosynthesis process, involves three stages: fixation, reduction, and regeneration. If a part has been removed from the diagram, it possibly pertains to one of these stages. The initial step, fixation, involves the enzyme RuBisCO incorporating carbon dioxide into an organic molecule, 3-PGA. For reduction, this organic molecule is reduced using electrons supplied by NADPH. In the final regeneration stage, RuBP, the molecule that starts the cycle, is regenerated to facilitate the continuation of the cycle.

In these steps, CO₂ from the atmosphere is converted into carbohydrates using ATP and NADPH energy. A cycle must be completed three times to produce a three-carbon GA3P molecule, and six times for a six-carbon glucose molecule. Notably, the cycle requires energy input from 12 ATP molecules and 12 NADPH molecules for the reduction step, and 6 ATP molecules for the regeneration phase.

To calculate the number of peptides that can be formed with arginine, tryptophan, cysteine, and valine, one must consider all possible combinations, with the formula 4^n, where n is the number of amino acids in the peptide chain.

The question is asking how many different peptides can be formed using the amino acids arginine, tryptophan, cysteine, and valine. To determine this, we must consider all the possible combinations these amino acids can create in a peptide chain. Each position in the peptide chain can be occupied by any one of the amino acids. Therefore, for a peptide chain of length n, the number of different peptides that can be formed is 4^n, because there are 4 choices for each position.

If we are dealing with dipeptides (chains containing only two amino acids), there are 4 choices for the first position and 4 choices for the second position, leading to 4 * 4 = 16 possible dipeptides. For tripeptides (chains containing three amino acids), the calculation would be 4 * 4 * 4 = 64 possible tripeptides. This pattern continues with the length of the peptide chain increasing. This concept also demonstrates the vast diversity possible with even a small pool of amino acids.
