Answer:
The correct option is 'a'
If osmotic pressure increases when a mussel is submerged in the water,the blood osmotic pressure also increases.
Explanation:
Mussels are bivalves that are found in fresh water as well as marine water.
They have bluish blood and small heart pumps the blood.Some mussels have red blood which contain hemoglobin that carry oxygen rather than hemocyanin.
The mussels show increase in blood chloride level and amino acid when the osmotic pressure of the water increases.
Submerging the mussel in the aquatic environment increases osmotic pressure of the mussel.
Answer:
is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.

Answer:
the correct answers are as follows
12:
b. Testcross- an organism with dominant phenotype but unknown genotype is crossed with homozygous recessive organism for the same trait. Based on the results obtained, if all offsprings have the same phenotype, then the parent is homozygous, but when a 1:1 ratio is observed in the offsprings, then the parent is heterozygous.
13.
e. Watson and Crick- they both used the crystallographic images from Franklin, analyzed them to first elucidate the 3D structure of the DNA and propose it to the world.
14.
c. Intracellular and commonly found in the cytoplasm- the receptors of steroid hormones are generally present within the target cell either in the cytoplasm or nucleus, since they alter gene expression.

e. Certain prokaryotes/bacteria- this is a process that will enable disease-causing pathogens to communicate and cooperate with their group, by the release of autoinducers that increase their cell density.
Answer:
e) a drive
Explanation:
We felt thirsty when we have fluid imbalance in our body either we have less water or we have more concentration of osmolytes such as sodium in blood. The brain detect the change produce the effect for the intake of water.
- However thirst is a vital primordial emotion that motivates us for fluid intake. So the emotion produces a drive to quench it.
- Some recent studies refers it as basic instinct to drink water.
