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:
The bonds that will break at high temperature are hydrogen, ionic and Van der Waal's interactions. Covalent bonds will not break.
Explanation:
The Chondrichthyes are the cartilaginous fishes including the sharks, rays,<span>skates and chimeras. The Osteichthyes are the bony fish. Both of these groups </span>became established during the Devonian Period about 400 million years ago. The Chondrichthyes <span>differ from the Osteichthyes in many respects, including their</span><span>

In autotrophic bacteria, chlorophyll is located in the infolded regions of the plasma membrane.
Autotrophic bacteria are those that can synthesize their own food. The energy can be derived either from sunlight or from chemical reactions. Only a few amount of bacteria are autotrophic. The examples of such bacteria are: green sulfur bacteria, purple sulfur bacteria, heliobacteria, etc.
Chlorophyll is the green colored pigment involved in the process of photosynthesis. The chlorophyll acts as a reaction center that absorbs the energy from sunlight to initiate the process of photosynthesis. The energy absorbed by other pigments is also transferred to the reaction center.
