Biology
1 answer:
exis [7]3 years ago
5 0

Answer:

1) A double Helix with complementary bases in the middle. The backbone is made of sugar and phosphates. The middle is bases

2) To hold the genetic info for the cell

3) To bring the genetic info from the nucleus to the ribosomes as DNA can't leave the nucleus

4) To bring amino acids to the ribosomes to help build a protein

5) A chain of amino acids held together by peptide bonds

6) Ribosomes

7) Because those are the bases that are complementary in DNA so they must be equal

8) It could lead to a mutation as it would cause the mRNA to code for a different amino acid and thus a different protein will be made

9) DNA is the blueprint for mRNA which will travel to the ribosomes and code for specific amino acids which will eventually build a protein

<u>Answer</u>: Bacteria through the nucleoid (number 5).

<u>Explanation</u>:

Both paramecium and bacteria are single celled organisms. However, they differ by the fact that the first one is an eukaryote and the second one a prokaryote.

Furthermore, they differ in their capacity to mutate and adapt to environmental changes. Bacteria have a simple internal structure that lacks any organelles and are very adept at adapting to environmental changes. Besides their capacity for high mutation rates, they are also capable of picking up genetic information from their environment through a process called <em>transformation</em>.

Through transofrmation, environmental DNA enter the living bacteria through its cell membrane. Double stranded DNA will have one strand dissolved through hydrolysis, whereas the second strand may recombine with the bacterial <em>chromosome (nucleoid)</em>. Thus, this new genetic material will become incorporated into the bacterium's genome.

How do we know that height in humans is a polygenic trait?
Elena-2011 [213]
We know that height in humans is a polygenic trait because it has a lot of variation. The height gene is controlled by at minimum three genes with six different alleles. If all of these alleles are dominant for the tall gene you will be tall if you are dominant for the short gene you will be short if there is no clear dominance between the two genes you will fall somewhere  in the middle.

What statement about the mechanism of hunger and satiety is true?
disa [49]

Answer:

The correct answer is: The ventromedial hypothalamus plays a role in satiety.​

Explanation:

The hypothalamus is a part of the brain that controls many important bodily functions and connects both the nervous system with the endocrine system. The hypothalamus consists of several nuclei that have diverse functions and are located in 3 different regions.

The nucleus that plays a role in satiety is the ventromedial nucleus, terminating hunger and giving a sensation of fullness. It also plays a significant role in thermoregulation, among other things.

Neuropeptide Y, on the other hand, is a peptide that is released to make us feel hungry and encourage us to intake food (primarily carbohydrates).

Cholecystokinin is a hormone released by the small intestines after we had a meal, and its function is to improve digestion and make us feel full.

Fat cells DO release leptin, but the function of this hormone is to produce satiety, by stimulating anorexigenic (meaning they take hunger away) hormones and inhibiting orexigenic ones, like Neuropeptide Y.
