Which of the following best describes how independent assortment results in inherited variations within a species and how it contributes to evolution?
A Independent assortment results from the copying of DNA during cell division and causes variations that are sometimes beneficial to a species
B Independent assortment results from the binary fission of a single cell and causes mutations that can be beneficial or harmful to a species
C Independent assortment occurs during mitosis and causes uncontrolled cell division which is harmful to a species
D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
Answers
Answer:
D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
Explanation:
During meiosis, the homologous chromosomes separate and segregate independently of each other. This process is referred to as 'independent assortment'. In consequence, different gene variants or 'alleles' localized in homologous chromosomes segregate independently of each other during gamete formation, thereby one particular gamete has an equal probability to carry either of these segregating alleles. Independent assortment generates genetic variation in the gametes, which can be beneficial or deleterious in a given environment.
The option that best describes how independent assortment results is D Independent assortment occurs when chromosomes separate during meiosis and causes variations that can be beneficial or harmful to a species
What is independent assortment ?Independent assortment is a phenomenon that occurs during meiosis, which is the process of cell division that produces gametes (sex cells). During meiosis, the chromosomes are randomly sorted into the gametes. This means that the alleles (different forms of a gene) on different chromosomes can be inherited together or separately.
This random assortment of alleles can lead to new combinations of traits, which can be beneficial or harmful to a species.

They look a little bit different. SA cells contain fewer mitochondria, fewer myofibers, and a smaller sarcoplasmic reticulum. This means that the SA node cells are less equipped to contract compared to the atrial and ventricular cells.

In one species of guinea pig, the gene for black fur is dominant while the gene for
brown fur is recessive. A male guinea pig with black fur and a female guinea pig with
black fur produce a female offspring with black fur. Which of the following BEST
describes why the trait for fur color is transferred from the parents to the offspring?
O Genetic mutations
O Acquired traits that are passed on through mitosis
O Environmental conditions such as the type of cage the owner keeps the guinea pig in
O Genes store hereditary information in the DNA of a cell, that leads to traits passing from one
generation to the next

Writing Assignment So, you have learned about how the denaturation of proteins works during lecture, and you have seen examples in these videos. Now you will write a 2-3 page discussion of protein denaturation putting all that together Make sure you cover both the academic side (lecture knowledge) and practical side (what is done and observed in the lab). Make sure the answers to the following questions are contained in your report. Do NOT just answer them separately, but rather incorporate them seamlessly in your writing. This is a very broad topic, so comprehensive coverage is hardly expected, but you should demonstrate a good beginner's understanding. As usual, reference any and all resources you use.
a. What are the various levels of organization that any protein structure may have that gives it its 3-dimentional shape?Which of these changes during denaturation?
b. For each change made to a protein solution that you have seen or read about how might it affect the interactions that are involved in a protein's shape?
c. What is the difference between precipitation of a protein and its denaturation? How might you tell the difference?
d. If changing the pH of an enzyme solution greatly reduces the activity of that enzyme without precipitation, how could you tell in the lab if it were the result of denaturation or just going to a pH that is just not a good one for the enzyme? And how would a change in pH impact or even stop enzyme function without denaturation? (Consider the enzymes that are active in your stomach, such as pepsin-discussed in Wikipedia.)
e. For changes that precipitate a protein, are some more likely than others to be denaturation?
f. Etc. If you find one aspect of what you've see more interesting, go ahead and learn more and expand that section of your report and keep the other sections more basic.
Answers
Solution :
Denaturing may be defined as the process where the protein they lose their shape and their function because there is a change in the pH level or in the temperature. Although the amino acids sequence also known as primary structure, it does not change. But the shape of the protein might change a little bit so much that it can become dysfunctional in which protein is considered to be denatured.
The enzyme, Pepsin, the breakdown protein in our stomach only operates at a very low pH level. At higher pH level, the pepsin's configuration the way the polypeptide chain is being folded up in a 3 dimension begins to change. The pH level of the stomach is maintained at a low level to ensure that pepsin continues for the digest protein and that it does not denature.
There are 4 levels of the protein structure --- they are the primary, the secondary, the tertiary and the quaternary.
The primary protein is a particular sequence of amino acids in each of the polypeptide chain that makes the protein. The final protein structure depends on this sequence.
Secondary structure arise from the interactions between the neighboring or nearby the amino acids as polypeptide starts folding into 3D form.
The tertiary structure is the most important of structural levels in determining.
The quaternary structure also applies to the proteins made from more than one polypeptide chain.

In quiet breathing, muscular effort is used mainly in inspiration, and expiration is largely passive, due to elastic recoil of the lung. It results in a pattern change between expiratory and inspiratory flow. Explain changes you observed in the recordings you obtained. 1 pts Enter your answer here
Answers
Answer:
During quiet breathing, the main muscular effort is made in the inhalation process and the expiration process is mainly passive as it depends on the inhalation.
The expiration occurs due to the elastic recoil that causes a decrease in volume. In this process, the contraction of the diaphragm helps in the inhalation which is least affected by the intercostal muscle. During quiet breathing, the rate of inhalation and expiration time is relatively proportionate to one another.

What is Breathing?Breathing is the process of moving air into and from the lungs to facilitate gas exchange with the internal environment, mostly to flush out carbon dioxide and bring in oxygen.

how and why does DNA change during meiosis
Answers
Answer:
When recombination occurs during meiosis, the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome breaks in the exact same location, leaving two free ends. Each end then crosses over into the other chromosome and forms a connection called a chiasma.

Hybrid
Corn
h
Short Height: 0%
Answers
Answer:
See the answer below
Explanation:
Normal height - H
Short height - h
Heterozygous - Hh
A cross involving heterozygotes would be Hh x Hh
Hh x Hh
HH Hh Hh hh
Since H is dominant over h;
HH and Hh would produce normal height phenotypes.
hh will produce a short height phenotype.
Thus;
Probability of normal height phenotype resulting from the cross = 3/4 or 75%
Probability of short height phenotype resulting from the cross = 1/4 or 25%
