Answer:
Eudora identified the chemical combination of nucleic acids as consisting of a chain of nucleotide monomers, each composed of a phosphate group, a pentose sugar (either deoxyribose or ribose), and one of four nitrogenous bases (adenine, guanine, cytosine, or thymine). This combination allows for the storage and transmission of genetic information within cells.

Why Did The Children In (III-A) And (III-E) Not Get The Disease When Both Fathers Had The Disease?
In the case of the children in (III-A) and (III-E) not getting the disease when both of their fathers had the disease, there are several potential explanations for why this could have occurred.
One possibility is that the children were exposed to the same form of the disease, but that the form of the disease they were exposed to was not as strong or as virulent as the form of the disease their fathers had. This could be due to differences in the strain of the disease, or even due to differences in the environment in which the children were exposed. In either case, the weaker form of the disease could be easier for the children’s bodies to fight off, making them less likely to contract it.
Another possibility is that the children had some form of immunity to the disease, either through natural immunity or through a vaccine. Natural immunity is when the body has been exposed to a similar virus or bacteria before, and as a result, has developed an immunity to it. Vaccines can also provide immunity to a particular disease, and the children may have been vaccinated before they were exposed to the virus or bacteria that their fathers had.

What happens to allele frequencies when Hardy-Weinberg conditions are met?
when Hardy-Weinberg conditions are met, the frequencies of alleles in that population will stay the same over generations
Hardy-Weinberg Equilibrium:
The Hardy-Weinberg theorem deals with Mendelian genetics in the context of populations of diploid sexually reproductive individuals. Under some assumptions, this theorem states that: Allele frequencies within the
population do not change from generation to generation. If the allele frequencies of a population with two alleles at the
locus are p and q, the expected genotype frequencies are p2, 2pq, and q2. This frequency distribution does not change from generation to generation once the population is in Hardy-Weinberg equilibrium. Hardy-Weinberg equilibrium can be disrupted by various forces such as mutation, natural selection, non-random mating, genetic drift and gene flow.

How does skeletal muscle respond to the nervous signals to result in
movement?
Skeletal muscle responds to nervous signals by contracting and relaxing in a coordinated manner, which results in movement. When a nerve impulse, or action potential, travels to a skeletal muscle fiber, it triggers the release of a chemical called acetylcholine from the nerve ending. Acetylcholine then binds to receptors on the muscle fiber, causing the muscle to contract.
The process of muscle contraction begins with the sliding of thin filaments called actin and myosin past each other. The myosin filaments have small, knob-like structures called cross-bridges that bind to the actin filaments and pull them along, causing the muscle fiber to shorten. As the muscle fiber shortens, it generates force, which can be used to move the body or an external object.
When the nervous signal to the muscle is turned off, the muscle relaxes and the actin and myosin filaments return to their original positions. This process allows skeletal muscles to respond to nervous signals and produce movement in a controlled and coordinated manner.

4. In a sample of yeast DNA, 31.5% of the bases are adenine (A), Predict the percentage thymine (T).
Explain your answer.
Answer:
In DNA, the four nucleotide bases are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair with each other in a specific way: A pairs with T, and C pairs with G. This means that if we know the percentage of one base, we can predict the percentage of its complementary base.
In your sample of yeast DNA, if 31.5% of the bases are A, then the percentage of T must be 100 - 31.5 = 68.5%. This is because the sum of the percentage of A and the percentage of T must be 100%.
Therefore, the percentage of thymine (T) in the sample of yeast DNA is 68.5%.

how do cells make tissues
Answer:
Body tissues grow by increasing the number of cells that make them up. Cells in many tissues in the body divide and grow very quickly until we become adults. When we are adults many cells mature and become specialised for their particular job in the body. So they don't make copies of themselves (reproduce) so often.
Explanation:
In a multicellular organism, cooperative assemblies of similar cells form tissues, and a cooperation between tissues in turn forms organs, which carry out the functions necessary to sustain the life of an organism.
Tissues are formed from the assemblage of cells and intercellular materials in various proportions in which one component predominates. In nervous tissue as an example, nerve cells predominate while in connective tissues such as Ligaments and Tendons, intercellular fibrous materials predominate.
How can insects help in toxicological analysis?

These substances may be chemical, biological, or radioactive in nature, and their presence can have serious implications for the safety of people, animals, and the environment.
This is because certain insect species are sensitive to certain toxins and can act as indicator species for their presence. Specifically, insects can be used in bioassays to test for the presence of toxins, as well as to measure the toxicity of the environment.

Which term describes the movement of materials from areas of higher to lower concentrations that does not require energy
Passive transport is the movement of materials from areas of higher to lower concentrations that does not require energy. The correct option to this question is C.
What is passive transport?Passive transport is a type of membrane transport that does not require energy to move substances across the cell membrane. Rather than using cellular energy like active transport, passive transport relies on the second law of thermodynamics to drive the movement of materials across cell membranes.
The main difference between active and passive transport is that active transport uses ATP energy to force molecules against a concentration gradient, while passive transport allows molecules to pass through concentration channels across membranes without the need for cellular energy.
Passive diffusion follows a concentration gradient. It refers to the transport of molecules from a place of higher concentration to a place of lower concentration without using chemical energy according to Fick's Law of Diffusion.
