Answer:
A
Explanation:
this is because, in smaller organism their SA/V ratio is large hence they have efficient transport of materials within their cells
Atlantic Cod is a marine fish. The fish has less salt in its internal body while the salt concentration in the sea water in which the Cod lives is high. Thus through the process of osmosis ( a process in which an element moves across a permeable membrane from regions of high concentration to the regions of low concentration) the salt moves from the ocean into the fish body. In such scenario the metabolism of the fish body gets disturbed, and there is an urgent need to remove the excess salt with the help of Kidney (through extremely concentrated urine) by going against the concentration gradient in order to maintain the homeostasis.

Answer:
1/128
Explanation:
In a diploid individual, 2ⁿ possible gametes can be produced, where <em>n</em> is the haploid chromosome number.
From those possible gametes,
is the number of gametes that will contain maternal chromosomes only
- is the number of gametes that will contain paternal chromosomes only
-
is the number of gametes that will contain a combination of both maternal and paternal chromosomes.
The probability that an individual spore will contain a set of chromosomes all of which came from the male gamete will be:

Answer:
Rabbits and snakes increase in number but grasses decrease in number.
Explanation:
If the population of hawk is decreases to half then the population of rabbits and snakes increases because hawk feeds on rabbits and snakes. The amount of grasses also decreases due to increase in the population of rabbits which feeds on these grasses. Hawks controls the population of rabbits and snakes when these hawks are decrease in number then the ecosystem will destabilize by increasing number of rabbits and as a result vegetative cover decreases quickly.
