Answer:
The benefits of genetic diversity include:
2- species survive despite negative mutations 4- species adapt to ever-changing environments 5-gene pool is strengthenedExplanation:
Mutations resulting from errors within gene replication frequently accumulate within species, becoming more stable over time. They lead to other forms of the same genes called alleles.
Several alleles within a population's gene pools leads to higher diversity. These may become beneficial, as the environment of the organism changes.
Mutations that confer benefits tend to help organisms survive and produce offspring, passing on these genes. However, some mutations may be deleterious/harmful and fatal. High diversity reduces the deleterious effects of some mutations on a population for a stronger gene pool i.e. the species survives.
How can point and frameshift mutations contribute to biodiversity of Earth? Explain your
answer.
Answer:
These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.
Explanation:
Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.
Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.
Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.

Answer:
Need more info please and thank you
Explanation:
I can help you but please give ne more info
Answer:
ATP is the form of energy that your cells require to perform their functions. This form of energy is made in the mitochondria in a process known as cellular respiration.
Explanation:
***I'm assuming that this question relates to respiration as it has to do with energy. ATP energy are products of cellular respiration. Along with ATP energy, we also have 2 more products, which is H2O and CO2.
We breathe out carbon dioxide since we don't need CO2 in our bodies and we sweat water by the amount of heat + energy you are using up.
***We need to undergo cellular respiration to obtain energy. To obtain this energy, you need the mitochondria as it is the powerhouse of the cell. The mitochondria creates that energy you need as a living organism.

Which processes change magma into igneous rock?
Answer:
Magma rises to Earth's surface, such as through a volcanic eruption, where it cools and hardens into igneous rock. On the surface, weathering and erosion break down the igneous rock into pebbles, sand, and mud, creating sediment, which accumulates in basins on the Earth's surface.

You are testing for nitrate reduction. The first test, which involves adding Trommsdorff reagent and dilute H2SO4, produces a blue color. Is the test positive or negative for nitrate reduction?
a. positive
b. negative
Answer:
The correct answer is - option a. positive.
Explanation:
Nittarte reduction is the test for the determinantion of the production of nitrate reductase enzyme through various test. One of the test is trommsdroff test.
This test involves trommsdroff reagent and dilute sulfuric acid that produce blue color if the reduction occurs and reductase present. This color is formed due to the conversion of ammonia to nitrate.

What statistical measure is used to measure narrow-sense heritability by comparing parents to their offspring
For assessing the almost full additive genetic variation while potentially avoiding biases that can occur when modeling close relatives is possible by correlating phenotypic similarity to degree of IBD sharing among conventionally unrelated people.
What is heritability?Heritability is an important genetics parameter is heritability. Traditional estimates based on family or twin research may be inaccurate because of genetic variance that is not additive or shared environmental factors.
The narrow-sense heritability supplied by uncommon or otherwise poorly labeled causative variations is often underestimated by those based on genotyped or imputed variants, on the other hand.
All variations across chromosome pairs are shared by identical-by-descent (IBD) portions of the genome, with the exception of fresh mutations that have developed since the last common ancestor.
Using phenotypic simulation with thousands of people to use an IBD-based technique (GREML-IBD) to evaluate heritability in unrelated individuals.

Refer to the diagram provided. This cell can conduct cellular respiration. Name a product of cellular respiration that is used as a reactant in photosynthesis?
CO2
ATP
Glucose
02
Answer: CO2
Explanation: A product of cellular respiration is Carbon Dioxide. Carbon dioxide is also needed for plants to go through photosynthesis. Therefore, that would be the product to cellular respiration and the reactant in photosynthesis.
A. CO₂
Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. The energy released is captured in molecules of adenosine triphosphate, or ATP, which then supply it to fuel other cellular processes.The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
Therefore, option A is correct.

Explanation:
The correct model shown is Crossing over will result in new genetic material.
What is crossing over?
When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the development of egg and sperm cells.
This process leads to novel allele combinations in the gametes (egg or sperm) produced, ensuring genomic variety in any offspring born.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father.
Therefore, The correct model shown is Crossing over will result in new genetic material.

Explanation:
138) Six-year-old Matthew broke his femur and one of his epiphyseal plates was damaged. Explain the role of the epiphyseal plate in longitudinal growth and predict the effects of a damaged epiphyseal plate on his future longitudinal growth.
Answer:
The function of the physis or growth plate is to allow the growth in length of the bones (both long as short) through the endochondral ossification process.
Explanation:
The epiphyseal plates are areas of active growth of new bone at the ends of the bones, made up of cartilage that hardens once the child is fully developed. Epiphyseal plates help determine the length and shape of the adult bone eventually. It is the last part of the bones to harden, and therefore they are vulnerable to fractures. The complication of the involvement of the growth plate is the deformity or lack of growth of the bone, leaving the limb twisted or shorter than the contralateral one.Growth disturbances are more frequent when the affected area is very large or when it involves the area of the knee joint. In cases of shoulder or wrist involvement, deformities rarely occur. The alterations are more common when the lesions occur in younger children, because they have a longer growth period.
