What is the complementary base to cytosine in DNA?
A uracil
B. thymine
C. adenine
D. guanine

Answer:

F. Both regulation and secretion

Explanation:

Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.

The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

Answer:

B. Anaphase

Explanation:

The stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.

The phase of mitosis which is shown below in the picture is Anaphase. During this phase, chromosomes break at centromeres.

Mitosis may be defined as a process where a single cell divides into two identical daughter cells.

Anaphase is the phase of mitotic cell division where chromosomes break into chromatids that are separate from each other and are pulled towards the opposite pole with the help of spindle fiber.

Therefore, the phase of mitosis which is shown below in the picture is Anaphase.

Explanation:

The following model is a model of a prokaryotic cell. It can be identified with the characteristic features of the cell and the cellular components present in this particular cell.

In this model, no nuclear envelope or membrane is present and it is present in the eukaryotes not in the prokaryotes, similarly, the other double membrane-bound organelles such as mitochondria not present in the prokaryotes.

Answer:

14 chromosomes

Explanation:

In the gametes of an organism, there are always half of how many chromosomes there are in the somatic cells of the organism. For example, if there are 4 chromosomes in the somatic cells, that means that there are 2 chromosomes in the gametes.

Somatic cells are body cells. They include everything from skin cells to brain cells to stomach cells.

Gametes are reproductive cells. They're the sperm and egg cells.

So if the muscle cells have 28 chromosomes, that means all somatic (or body) cells of that organism have 28 chromosomes.

So the gametes would have half of that amount:

28/2 = 14

So the sperm cells of this organism would have 14 chromosomes.

Complete question:

Which characteristic is most useful in correlating Devonian-age sedimentary bedrock in New York State with Devonian-age sedimentary bedrock in other parts of the world?

a. Color

b. Index fossils

c. Rock types

d. Particle size

Answer:

b. Index fossils  

Explanation:

Fossils are animal and vegetable rests found in different strata of sedimentary rocks. Sedimentary layers deposit chronologically, so they are used to reflect history. They keep in each layer some of the forms of life that inhabited that area in the past. These fossils turn to be very useful while dating ages. The term Index fossils refer to those fossils that only existed in a given era or geological period during evolution.

Index fossils must:

In the exposed example, we are looking for a correlation between the Devonian-age sedimentary rock layers from New York with the Devonian layers of other parts of the world. This comparison is the same period (Devonian) and in places that might be far away from each other, meaning there was a wide geographical distribution of the species.

A quick evolution and extinction contribute to narrow the geological period of their existence, increasing the chronological precision. Widely distributed fossils allow geologists to establish relationships between rocks that are far away from each other.  

Answer:

the Galaxy

Explanation:

The astronomical body which is the highest in hierarchical order is the Galaxy.

7.5% of 217 = 16.275

At end of 1 year bisons = 217 - 16.275 = 200.725

7.5% of 200.725 = 15.054375

At end of 2 years bisons = 200.725 - 15.054375 = 185.670625 (Rounding that to the tens)

Answer:

After transcription, some RNA molecules are altered to contain bases not encoded in the genome. Most often this involves the editing or modification of one base to another, but in some organisms can involve the insertion or deletion of a base. Such editing events alter the coding properties of mRNA.

Answer:

B. The prairie dog population will decrease, the red-tailed hawk population will decrease, and the bison population will increase.

Explanation:

I'm not given context; however, I am assuming that the prairie dog preys on the bison because the bison is commonly known as a herbivore.

If another predator who preys on the prairie dog is introduced, there is increased competition with the red-tailed hawks. Although this doesn't directly impact the population of red-tailed hawks, it reduces its food supply (of the prairie dog) because it is being shared, so it will have less food to grow at the optimal level.

With the increased consumption of the prairie dog, naturally, that would leave its prey; the bison, to have a lower level of predation, thereby the population increasing.

Answer:

look,Examples of X-linked recessive conditions include red-green color blindness and hemophilia A: Red-green color blindness. Red-green color blindness means that a person cannot distinguish shades of red and green (usually blue-green), but their ability to see is normal.

Red-green colorblindness is an X-linked recessive disorder in humans.

An illness that disturbs the normal physical or mental functions of any individual.

The allele of colorblindness resides on X-chromosome, which means the male is affected with one mutant allele. while both the alleles are required to be mutant to cause the disorder in females. Another example of X-linked disorder includes Hemophilia. Red-green colorblindness reveals that an individual cannot able to differentiate the shades of red and green but occupy the normal vision.

Therefore, Red-green color blindness is an X-linked recessive disorder in humans.

Answer:

hi

i'm not really sure but i think its the second option

Explanation:

enzymes when they are active usually hydrolyzes things

so in the second one we read that we can see unpaired nitrogenous bases

these bases are:

adenin timin citosin goanin

those are for DNA . in RNA timin is changed with uracil

so these means the hydrogen bond between them are hydrolyzed by enzyme

so we see the effect of enzyme on DNA

Answer:

42. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine

Explanation:

43.Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

33 terms. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural five-carbon ribose sugar found in RNA has been replaced by an unnatural four-carbon threose sugar.
