<u>Answer</u>: Option D Pp,PP and pp


<u>Explanation</u>:

  • <em>Heterozygous</em> plants are the ones which carry two different alleles, one dominant and the other recessive.
  • Thus, the genotype for the purple flowered heterzogyous individuals would be Pp.
  • If these are crossed together, Pp X Pp——————> PP, Pp, Pp, pp
  • Thus, from the given cross the different possible genotypes for the offsprings comes out to be PP, Pp and pp.

There is a Punnett square representation for the cross attached for reference.

Which of these best explains why mitochondria are called the "powerhouses" of the cell?
Sindrei [870]

<em><u>Answer:</u></em>

They generate chemical energy in the form of ATP.

<u><em>Explanation:</em></u>

Mitochondria are the powerhouses of the cell because they "burn" or break the chemical bonds of glucose to release energy to do work in a cell. This releases energy (ATP) for the cell. The more active a cell (such as a muscle cell), the more mitochondria it will have.

What is not a dissolved gas present in the ocean
liraira [26]

The correct answer is option B, hydrogen.

The majority of the atmospheric gases are found in the sea water solution. In supplementation to oxygen and nitrogen, the most profusely found gas in the atmosphere, that is, carbon dioxide is found in the ample concentrations in the ocean waters.  

However, hydrogen is not present, and if found it is found in minute concentration. Of the gases, nitrogen is the most abundant gas found in seawater, while oxygen is the second most abundant, and carbon dioxide is the most soluble gas, and one of the various constituents, which influences the pH balance of the ocean.
