Mitosis splits a parent cell into two daughter cells, creating two identical cells. Meiosis is a sexual reproduction
Answer:
The enzyme denatured and therefore cannot catalyse any more reactions. Once an enzyme is denatured, it cannot be reversed.
Answer:
a) This method of stickiness is advantageous over covalent interactions because it is weak and easily reversible.
b) The feet are equipped with millions of septae which collectively produce a synergistic effect that produces a powerful adhesive effect.
Explanation:
Geckos have their feet studded with tiny hair-like substances called septae, and these substances interact with the surfaces on which the Gecko climbs using weak van der Waals forces to produce stickiness.
a) The van der Waals interactions for the purpose of climbing is of more advantage over the covalent method of interaction because climbing involves a repetitive action of adhesion to the surface and destruction of such adhesion, and this involves the creation and the breaking of the bonds between the two surfaces easily. van der Waals forces being easily broken helps to achieve effective climbing. If the method of interaction is with a comparatively strong bond, the speed of creation and destruction of such bond is reduced, and the effectiveness of climbing is reduced.
b) Although van der Waals forces are weak forces, each foot of the wall Gecko has millions of septae that each create a van der Waals interaction, and the collective interactions produce a powerful adhesion causing the feet to stick effectively.
are you talking about the sexuality? like being asexual? sorry if not? if ur not u can respond to this and i will delete it
<h2><u>Answer:</u></h2>
The correct option is B (The longer-spined sea urchins existed before the shorter-spined sea urchins.)
<h3><u>Explanation:</u></h3>
The more drawn out spined ocean urchins existed before the shorter-spined ocean urchins.
Since the shorter spined urchins are higher up, that demonstrates that they developed from the more drawn out spined urchins, implying that having the shorter spines was useful to them as an animal types, so the shorter spines came AFTER the more extended spines.
