Explanation: I feel as if it could be all of them except C
Three conditions (or inhibitors) will stop the enzyme's reaction from taking place. If another substance attaches to the site first the the reaction will not take place because the substrate can no longer attach to the active site. Conditions within the cell like temperature and acidity will also inhibit the reaction because it will change the shape of the active site which is very specific for the substrate that needs to attach to it. The enzyme will then become ineffective.
"Predators" directly control the balance of plant eating wildlife (and some omnivore and carnivores as well).
That is false. Ecology is the study of relations of organisms to one another and to their physical surroundings. Cell biology is the study of cells and their functions.
Answer:
0% (none)
Explanation:
The female drosophila is heterozygous for X-linked recessive mutation. An X-linked recessive mutation is expressed in females only when present in the homozygous state. Therefore, the female progeny should have two copies of the mutant allele to express this mutation. Let's suppose that the genotype of the heterozygous female is X^cX and that of the male is XY. The cross would obtain progeny in following ratio=
X^cX x XY= 1/4 X^cX: 1/4 XX: 1/4 X^cY: 1/4 XY
Since none of the female progeny is homozygous recessive (X^cX^c), the cross would not obtain any female progeny expressing the X-linked recessive mutation.
