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.

MatroZZZ [7]

Answer:

Option-(A): In an illustrated flowchart, the movement of carbon atoms through an aquatic food chain is indicated by arrows.
Option-(C)- An increase in the population of scavengers.

Explanation:

The ecological pyramid is comprised of different level of organisms as the energy flow occur through them in a more directed form inside the different spheres depending upon the medium for energy transmission across the given parameters or area. As, the arrow provides us with a more directed way for understanding the transmission of energy through different organisms and there respective levels inside the ecological pyramid.

While, the increase in the level of scavengers or the animals which consumes the left overs of other living beings is balanced with the addition of the secondary consumers to the aquatic ecosystem.As, it will provide equal chances and energy to the different beings inside the ecosystem.
