Answer: reproductive cells are haploid
Explanation: mammals are diploid. In sexual reproduction each paren contributes a haploid set, which is what each reproductive cell
Answer:
The correct answer will be option-Base analog
Explanation:
5-bromodeoxyuridine is a synthetic nucleoside which is formed by deaminating the 5-Bromodeoxycytidine.
The BrdU once incorporated in the DNA of replicating cell during S phase binds the adenine which shows that it replaces the thymidine which usually binds the adenine.
Since BrdU binds the adenine, therefore, it acts as the analogue of the thymidine and also can cause mutations thus acts as a mutagen.
Therefore, it acts as a base analog and thus is the correct answer.
Answer:
Simile
Definition: The likening of one thing to another (usually translated using the English words "like" or "as".(1)
For a thousand years in your sight are like a day that has gone by, or like a watch in the night. (Psalm 90:4)
"When calamity overtakes you like a storm,
when disaster sweeps over your like a whirlwind,
when distress and trouble overwhelm you." (Prov. 1:27)
Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full or dead men's bones and everything unclean. (Matt. 23:27)
His head and hair were white like wool, as white a snow, and his eyes were like burning fire. (Rev. 1:14)
Explanation:
Answer:
Shallow water is the barnacles´ <u>realized</u> niche.
Explanation:
The case of Balanus and Chthalamus is an example of competitive exclusion, which refers to the exclusion of the inferior competitor -<em>Chthalamus</em>- by the superior competitor -<em>Balanus</em>- when there is not habitat differentiation, and both species can not share the same niche. In this case, the dominant species occupies part of the fundamental niche of the inferior competitor -<em>medium to low tides</em>-.
The fundamental niche refers only to physic conditions in which a species can live and survive in the absence of any interaction with other species. In the case of <em>Chthalamus</em>, the fundamental niches are the upper intertidal zones, the middle intertidal zone, and the lower intertidal zone.
The <u>realized niche</u> refers to the restricted conditions in which a species can live and survive as a result of environment physic characteristics and the interaction with other species. <em>Chthalamus </em>´ realized niche is the shallow waters. It can not live in the middle intertidal zone because it competes with <em>Balanus</em> and this last species is the dominant one so it occupies that area. <em>Chthalamus</em> can not live either in deep water because it is predated by other species.
<span>Similar to plants, animals also dislike too much exposure from light. The presence of light makes the animals move away from the source, this phenomenon is called phototropism. Some animals are incapable of resisting the light and can differentiate in advance how to behave during this situation. Phototropic creatures have a physical mechanism that does not allow them to be repulsed or drawn towards the light.</span>
