List the six nitrogen bases that would pair with the following sequence of bases in a strand of DNA : T C G A C A

Answers

Answer: thymine (T) Cyostine (C) guanine (G) adenine (A)

Explanation:

Guanine (G) is complementary to cytosine (C), and adenine (A) is complementary to thymine (T). Hence, the nitrogenous bases that would form for the DNA bases TCGACA are AGCTGT.

     

How does base pairing take place in DNA?

A DNA double helix is joined together by the hydrogen bonds that are formed between the nitrogenous bases in the opposite strands. Adenine (A), Guanine (G), Cytosine (C), and Thymine (T) are the nitrogenous bases present in the DNA. Both adenine and guanine are purines. They make bonds with pyrimidine.

Adenine (A) of one DNA strand makes a double bond with Thymine (T) of the opposite DNA strand. The guanine (G) of one DNA strand makes three hydrogen bonds with the cytosine (C ) of the opposite DNA strand. As there are three hydrogen bonds present in guanine and cytosine (GC), they require more energy to break the bond. Adenine and thymine (AT) have two hydrogen bonds, hence they require less energy than GC bonds.

Hence, in a DNA strand, the complementary strand of TCGACA is AGCTGT.

A. sweating
B. burrowing underground
C. taking in more calories
D. wearing a jacket

Answers

Answer:

A. Sweating

Explanation:

I just took it <3

The option which is an example of an automatic regulatory reaction is: A. sweating

Automatic regulation can be defined as a biological process that occurs within many living organism due to the function of an internal adaptive mechanism that typically works to mitigate (lessen or adjust) its system's response to stimulus.

Generally, the body organs and system that are considered to carry out some degree of automatic regulation are:

The brain.The heart.The kidney.

Hence, an automatic regulatory reaction is a biological process that happens in response to other bodily process and stimuli.

For instance, the nervous system produces an automatic regulatory reaction to emotions (fear), illness and heat such as sweating.

Sweating is an automatic regulatory reaction of the human body to protect and mitigate the effects of an extreme change in temperature (heat).

What is electronegativity?

The term "electronegativity" describes how attracted an atom is to the bonding electrons in molecules as opposed to other atoms.

American chemist Linus Pauling developed a set of dimensionless variables known as electronegativity values that vary from a little under one for alkali metals to a maximum of four for fluorine.

Electropositive elements are those that are on the left of the periodic table and have low electronegativities. We shall use the key attribute of the order of electronegativities F > O > N > C to explain the chemical properties of organic molecules.

Therefore, Zinc 1.65, Chromium 1.66, Tungsten 2.36 and Iodine 2.66.

What is ecosystem ?

An ecosystem is the unit of ecology, a structural and functional unit of where the living organisms dwell with each other and with their surrounding environment and the term was  coined by A.G.Tansley, an English botanist, in 1935.

The structure of an ecosystem can be up two types such as Biotic Components and Abiotic Components, both the components are interrelated  where the flow energy and components occur throughout the boundaries.

Biotic components belongs to all living components which can be classified into autotrophs, heterotrophs and saprotrophs. Autotrophs are the producers like plants which make food independently by photosynthesis.

The organisms that depend on other organisms for their food called as consumers or heterotrophs, it can be classified into primary consumers, secondary consumers and tertiary consumers.

Primary consumers are herbivores, Secondary consumers get energy from primary consumers can be either carnivores or omnivores. Tertiary consumers get energy from on secondary consumers.

Quaternary consumers prey on tertiary consumers, Decomposers include saprophytes such as fungi and bacteria depend on dead and decaying matter.
