it describes an event the writer has witnessed
One species called the naked mole-rat, has some unique differences. They have a social structure similar to that of ants and bees, they are smaller in size and are mostly ectothermic. They live in harsh, dry scrub land habitats and forage mainly on underground tubers which are widely dispersed. Why you think this species evolved back to an ectothermic life style rather than staying endothermic like all other mammals
Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.

Explanation:
Protein synthesis consumes four high-energy phosphate bonds per added amino acid. Transcription consumes two high energy phosphate bonds per added nucleotide. Calculate how many protein molecules will have been made from an individual mRNA at the point when the energy cost of translation is equal to the energy cost of transcription. Assume that the nucleotides in the coding portion of the mRNA constitute 5% of the total that are transcribed.
Answer:
30 protein molecules per mRNA molecule
Explanation:
In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.

What observation supports the claim that earth rotates
Answer:
The most direct observational evidence for Earth's orbital motion is the apparent shift of nearby stars after six months, as the Earth moves from one side of its orbit to the other. Because of the large distance to even the nearest start, this parallax shift is too small to been seen without a telescope.

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
Answer: it is D
Explanation: if you get a gene from your parents it's a gene you get it's not a mutation because if it was it would've been like a calico color but since it's just black it's D.

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.
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.

The diagram below shows three families. Which set of parents has the highest fitness?
A
the parents of the single child
B
the parents of two children
C
the parents of the big family
Answer:
C. the parents of the big family
Explanation:
In biology, an organism that produces as much offspring is said to have a higher fitness compared to its counterpart. It is said to be biologically fit than the rest.
Therefore, in the same vein, the parents that has the biggest family is the most biologically fit of the three families.

The speed with which force is developed by skeletal muscles is determined by the Group of answer choices myosin ATPase isoform. Ca2 ATPase activity. sarcoplasmic calcium concentration.
Answer:
myosin ATPase isoform.
Explanation:
Skeletal muscle is also known as voluntary muscle and it can be defined as a type of muscle connected with the skeleton by tendons, so as to form a mechanical system that enables the movement of the limbs and other body parts with respect to another. Skeletal are found only in vertebrates.
Basically, the length and shortening velocity determines the amount of force a muscle would generated. When a muscle is at its ideal (resting) length, it generates the greatest amount of force while it generates the least amount of force when stretched or shortened with respect to the resting length
The speed with which force is developed by skeletal muscles is determined by the myosin ATPase isoform.

If a cytosine replaces a guanine in a strand of DNA, this is known as what type of mutation?
Substitution mutation
Deletion mutation
Insertion mutation
Corruption mutation
Answer:
substitution
Explanation:
c replaces g. does not cause a frameshift mutation so it is not insertion or deletion, and i have no clue what corruption is when there is the word "replace" it is probably substitution.
Answer:
Substitution mutation
Explanation:
Mutation refers to a change in the genetic sequence of an organism. Mutation can be of different types depending on how it occurs. A type of mutation called SUBSTITUTION MUTATION involves the replacement of a nucleotide base by another in a gene.
For example, as stated in this question, when a cytosine (C) replaces a guanine (G) in a strand of DNA, it is called SUBSTITUTION MUTATION because guanine base replaces cytosine base in the sequence.
