If the sperm of a boa constrictor has 18 chromosomes, how many chromosomes will each skin cell of the snake have?
Answers
Answer:
18 chromosomes
Explanation:
If the sperm of a boa constrictor has 18 chromosomes, the number of chromosomes that each skin cell of the snake will have is 36 chromosomes.
What is meiosis?Meiosis is the process of gamete formation where each daughter cell or gamete contains half the number for f chromosomes as the parent cell.
According to this question, the sperm of a boa constrictor has 18 chromosomes. The sperm is a gamete formed as a result of meiosis.
Therefore, If the sperm of a boa constrictor has 18 chromosomes, the number of chromosomes that each skin cell of the snake will have is (18 × 2) = 36 chromosomes.

define analogous structure and provide an example
Answers
Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below, look similar on the outside.
Similar features in unrelated organisms are referred to as analogous structures. These structures are comparable not because they have a shared ancestor but because they accomplish the same task. Sharks and dolphins, for instance, even though they are unrelated, both have fins.
What is an analogous and homologous structure?Analogous structures, as opposed to homologous structures, are traits of different species that evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.An insect's wings and a bird's wings are similar in structure. Although each of these species utilise their wings to fly, the origins of their wings are different.Analogous organs have comparable functions, while homologous tissues share a similar embryonic origin.For instance, the bones in a human arm and a whale's front flipper are anatomically similar.The constructions here are not comparable. A butterfly's wings and a bird's wings are analogous but not homologousTo learn more about analogous structure, refer to:

ATP is a(1 point)
storable form of energy.
usable form of energy.
form of energy that can be used and stored.
form of energy that can be stored and released as heat.
Answers
Hello there!
Your answer should be ATP is a stored form of energy.
You see, Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. Hope this works!

a storable form of energy

C. Chromatids will have just moved toward opposite poles.
D. One much larger cell will be produced through nuclear fusion.

Answer:
i think its b i could be wrong
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.

If shaded symbols indicate having a dominant trait, what must be the genotype of the father in this pedigree chart?
Answers
Answer: The father must have a hetero'zygous genotype since both his offspring show the recessive trait even though he shows a dominant trait!
Answer:
Heterozygous
Explanation:
The offspring both carry recessive genes. The recessive gene will show up more often if one of the parents are heterozygous of the gene along with the other having recessive.
If the father was had both of the dominant traits, the offspring would inherit his trait instead.
When interspecific interactions lead to competitive exclusion, the weaker competitor is forced to retreat to a more restricted niche (its realized niche) than it otherwise would inhabit in the absence of the competition (its fundamental niche). This is what happens between Balanus and Chthamalus
Answers
Answer:
The places where the species can thrive principally because of its characteristics is known as the fundamental niche, on the other hand, the place where the species is living is known as the realized niche. In the intertidal region, the species Balanus and Chthamalus compete for space. In comparison, Balanus is a bigger barnacle that can colonize the place more effectively than Chthamalus.
This competition for space makes Chthamalus displace into higher regions where water is not the same as in lower levels. The fundamental niche of Chthamalus comprises both lower and higher levels, while the realized niche for Chthamalus is the higher levels. In case, if the competition with Balanus was non-existent, the Chthamalus would occupy the lower levels.

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.
Answers
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.

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.

How can point and frameshift mutations contribute to biodiversity of Earth? Explain your
answer.
Answers
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.
