Answer:

Complementary pairing held by hydrogen bonds

Explanation:

A DNA molecule is polynucleotide made up of nucleotide subunits (four). The nucleotides are Adenine, Guanine, Cytosine, and Thymine. These nucleotides are arranged on the DNA in two long chains. Each of these chains is called the DNA strand. The base portions of the nucleotides are held together by hydrogen bonds. This pairing of nucleotides is responsible for the double-helical structure of DNA.

Hydrogen bonds hold together complementary base pairs i.e. each base held together is complementary to one another. Complementary base pairing is a phenomenon whereby in DNA, Adenine (A) always binds to Thymine (T), while Guanine (G) always binds to Cytosine (C).

Note that, Adenine and Guanine are purine bases while Cytosine and Thymine are pyrimidine bases. In the nucleotide base pairing in DNA, purines binds to pyrimidines and vice versa

Which of the following are common traits of chloroplasts and mitochondria?
Delvig [45]

Answer:

c. Both have their own DNA.

Explanation:

Both chloroplast and mitochondria are semi-autonomous organelles which means that they both have their own DNA. Both of these organelles have a circular DNA and make some of their own proteins by themselves. Both are double membrane-bound organelles. Chloroplast has a third membrane system called thylakoid.

Chloroplasts are found in the plant cells only as they are the site for photosynthesis. Mitochondria are present in both plant and animal cells and are the site for cellular respiration to produce energy to support the vital functions of cells.

Explain why the use of the term “theory” in science is different from the use of the word “theory” in everyday language.
kari74 [83]

Answer:

In everyday language a theory means a hunch or speculation. Not so in science. In science, the word theory refers to a comprehensive explanation of an important feature of nature supported by facts gathered over time. Theories also allow scientists to make predictions about as yet unobserved phenomena".

Why is death by predator more natural or right compared to death by starvation
kirza4 [7]
Death by a predator is more natural because it follows the rules of the food chain and keeps nature in balance, keeping the environment healthy. However, whenever an animal dies of starvation, it means the food chain is out of balance since the animal wasn't in an environment where it could find something to feed off of.
