Answer:
Sharp-spined cactus
Explanation:
Given, that N allele is required for the production of spine and S allele will produce sharp sines.
True breeding sharp spined cactus: NNSS
spineless cactus: nn__ ( we can't fix the allele for second gene since it has not been mentioned as true breeding )
Their progeny: NNSS X nn__ = NnS_
So the progeny is going to be sharp spined because both the dominant alleles N and S are present.
Answer:
The shape of the enzyme determines which chemical reaction it will speed up.May strain the bonds of the substrate or put chemical groups of the active site in the correct position to speed up the reaction.
False because extrusive rocks have fine-grained texture due to the rapid cooling of magna above the earth surface. On the other hand extrusive rocks have course grained texture due to slow cooling of magna beneath the Earth's surface
No bc Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP<span>). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called </span>aerobic respiration<span> and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.
