Ans.

A substitution mutation can be defined as a mutation, which occurs due to exchange of a nitrogenous base for another (such as adenine to cytosine). This mutation can change the sequence of DNA and may results in a completely different gene product, sue to change in codon sequence.

The sequence 'A—G—T—G—G—A—T' represents a substitution mutation for normal nucleotide sequence as second base (cytosine) is exchanged with guanine in mutated sequence.

Thus, the correct answer is option). 'A—G—T—G—G—A—T.'

Why<br> are<br> non-engineered or owner-built structures more vulnerable to hazards?

Bond [772]

Answer:

Non-engineered/owner-build structures are more vulnerable because they can be poorly built. Without proper knowledge to build the right structure, the structure is more at risk of abnormalities or destruction from hazards such as rain, hail, strong winds, and debris.

KonstantinChe [14]

Gluconeogenesis is a metabolic pathway that results in the generation of glucose from non-carbohydrate molecules, from breakdown of amino acids or fatty acids and from other steps in metabolism that include pyruvate and lactate. This pathway is one of several main mechanisms used by humans and many other animals to maintain blood glucose levels<span>, avoiding low levels of blood glucose.</span>

If the sun were to suddenly stop providing energy to Earth, most ecosystems would vanish. Which of the following ecosystems woul

Alchen [17]

Answer:

The correct answer is C) benthic ocean

Explanation:

Sun is the ultimate source of energy for almost all the organisms present on the earth. The organism that especially lives on land are highly dependent on solar energy because all the plants and most algae require sunlight to make their food and they are the primary produces on which other organism are dependent.

Benthic ecosystem are the ecosystem that is present at the very depth of the ocean or on the ocean floor. So in that much depth, there is very little or no penetration of sunlight occurs. So the ecosystem there does not directly depend on sunlight for there survival. So they benthic ocean ecosystem would likely survive the longest.
