Read the comments about translation from the two students below.
Student A: "The purpose of translation is to convert the sequence of bases of mRNA into a polypeptide chain of amino acids to form proteins."
Student B: "The purpose of translation is to make a duplicate copy of DNA."
Which statement about the students’ comments is correct?
Student A is incorrect, because the purpose of translation is to convert DNA to RNA.
Student B is incorrect, because replication is the process that makes a duplicate copy of DNA.
Student A is correct, because translation occurs in the nucleus.
Student B is correct, because the DNA must be copied before mitosis.
The study of genes and inheritance is called genetics.
The correct answer is option B.
The translation is defined as the process in which mRNA is read by the ribosome and gets the amino acid to form the polypeptide and protein. Student two claimed is the process replication.
Replication is defined as the process of formation of new DNA from the old DNA.
According to the student, student 1 is correct.
Hence, option 2 is correct.

What is the “new” base found in RNA?
Answer:
RNA is a polymer with a ribose and phosphate backbone and four different bases: adenine, guanine, cytosine, and uracil. The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine.

Measuring Cellular Respiration
A student wanted to compare germinating pea seeds (growing) and nongerminating pea seeds
(not growing). She wanted to test two variables: germinating vs nongerminating peas at two
different temperatures: 10° C and 25° C.
The student proceeded to set up two electronic water baths: a warm water bath (25° C) and a
cold water bath (10°C). She also set up four respirometers: two containing germinating peas
and two containing non-germinating peas. Where would she need to place the respirometers in
terms of water baths to ensure that she was setting up a controlled experiment?
Statesi
Answer:
Follows are the solution the given choices:
Explanation:
The four approaches represent are arranged as follows:
Two approaches represent must be positioned in the [tex]10^0 \ C[/tex] water bath. Another respirometer to pea seeds so one respirometer to pea seeds without germinating.
She must put 2 breath meters at the [tex]25^0 \ C[/tex] water bath. Yet another respirometer to pea seeds or one respirometer to pea seeds without germinating.
The regulation would be carried out after germinating as well as nongerminating pea seed to bathometer in [tex]10^0 \ C[/tex] water bath.
What is a stinging cell that is a distinguishing feature of all cnidarians
Corals, sea anemones, jellyfish, and their cousins make up this phylum. Cnidocytes, specialized stinging cells that line the tentacles of Cnidaria, are used to capture prey.
What cnidarians having characteristics of stinging cell?Cnidarians have specialized cells called cnidocytes, sometimes known as “stinging cells,” which contain nematocysts.
These cells, which are concentrated on the animal's mouth and tentacles, have the ability to use toxins to paralyze prey. The coiled threads in nematocysts may be studded with barbs.
Nematocysts are unique cellular weapons employed for both predation and defense found in jellyfish, sea anemones, and other cnidarians.
Therefore, Nematocysts are made up of a pressurized capsule with a coiling thread like a harpoon inside.

The table indicates a(n) __________ in greenhouse gases, which should in turn cause a(n) __________ in global temperatures.
Answer:
Since there is no graph attached, the best I can do for now is tell you the possible answers based on the blanks.
A rise in greenhouse gases, should in turn cause a rise in global temperatures.
A decrease in greenhouse gases, should in turn cause a decrease in global temperature.
Some greenhouse gases are good for the atmosphere, but air pollution adds to it and causes more greenhouse gases to be added to the atmosphere, and therefore raises the Earth's temperature over time. This could be dangerous to species all over the planet as they may not be able to adapt.
If you add the table, I can answer more accurately.

These puppies were born in the same litter to the same parents, but they have different traits for the feature of toenail thickness. One puppy has thick toenails, one has thin toenails, and the third has medium toenails. How did these puppies end up with toenail thicknesses that are different from one another even though they have the same parents? How did the gene combinations result in the different traits?
Answer:
Maybe even though they got the same parents it could be dealing with the genetics or the different DNA coming for the parent's genes.

Which term refers to a fertilized egg after the cells have begun to differentiate?
A. Blastocyst
B. Fetus
C. Embryo
D. Zygote
Answer:
D
Explanation:
Blastocyst refers to a fertilized egg after the cells have begun to differentiate. So, the correct option is A.
What is Blastocyst?A ball of cells known as a blastocyst develops in the first five to six days of pregnancy, shortly after a sperm fertilizes an egg. It embeds itself in the uterine wall, developing into an embryo and subsequently a fetes.
A healthily developed embryo will include six to ten cells three days following fertilizations. The fertilized egg develops into a blastocyst, a rapidly growing ball of cells, on the fifth or sixth day. The innermost collection of cells will develop into the embryo. The outer group will develop into the cells that support and safeguard it.
Within the first two weeks following conception, a developing, fertilized egg is known by a variety of names, include zygote, morula (day 4), or blastocyst (day 5). About 10 weeks after the previous menstrual cycle, or 8 weeks after conception, the embryonic period begins.
Therefore, the correct option is A.

Question: Will weather changes (drought/flooding) over
time cause changes in the beak depth of a bird
population?
1. Claim:
Answer:
Changes in the environment affect the food sources available for birds. For example, if a flood was to occur, there would be an abundance of fish to birds to eat. So birds with bigger beaks will be able to eat fish, to live and reproduce offspring with bigger beaks. While birds with smaller beaks will not be able to catch fish to eat, therefore decreasing the population of birds with smaller beaks.

Humans have a double circulation system. There is a low pressure circulation and a high pressure circulation.
Explain how the structure of the heart enables it to pump blood into two circulations at different pressures
The cardiac muscle in the heart is myogenic, thus allowing it to keep its pace. There is a septum dividing the two circulations from each other in the heart, this allows for there to be pumping chambers (or two ventricles.) Each ventricle pumps to its own circulation. But the left ventricle is more muscular than the right. Thus this allows for higher pressures to be built in the left ventricle, therefore blood can be pumped around the whole body by the left ventricle. The right ventricle is less muscular as it only has to build up enough pressure to pump blood to the lungs.
