Answer:

The correct answer is: homologous chromosomes.

Explanation:

Diploid species like us humans have two sets of the same 23 chromosomes: 1 set of chromosomes is inherited from our mother, the other set we inherit from our father, making up a total of 46 chromosomes in every somatic cell (sexual cells have only one set of chromosomes - they're haploid).

Two chromosomes are homologous when they belong to the same pair and have the same genetic information, although they can have a few variations. These variations from one homologous chromosome to the other are called alleles and represent the different phenotypic variables that can result from the same gene. If these alleles are different from one another, only one of them will express itself (there are a few exceptions, like blood type) as the organism will be heterozygous for this trait; if the alleles are the same, the individual will be homozygous for the trait.

This is the basis for Mendelian inheritance.

What do anaerobic organisms have in common with photosynthetic organisms?

Dvinal [7]

Ans is option C. They both need an energy source in order to survive.

Energy is an absolute necessity to survive on this earth. All living organisms need energy be it anaerobic or photosynthetic. Photosynthetic organisms can make their own food in the presence of sunlight by photosynthesis and harness energy from it. Anaerobic organisms can also make their own food in the absence of sunlight with the help of inorganic molecules like hydrogen sulfide (H2S), ammonia (NH3), sulphur (S) etc.

Its just that anaerobic organism's way of harnessing energy is different from those of aerobes/photosynthetic organisms but they need energy source for sure.
