The answer you are looking for is C. Nitrogen. Commonly found as Nitrite 
(N3) or Nitrate (N2) nitrogen is a key element required by all life. Nitrogen is most often released back into the atmosphere by micro-organisms during the decomposition of organic matter, and into the ground through decomposition and defecation (Pooping).

In garden peas, one pair of alleles controls the height of the plant, and a second pair of alleles controls flower color. The al
Lerok [7]

Answer:

The parent's genotypes are:

Ddpp - tall, white parent

ddPp - dwarf, purple parent.

Explanation:

This question involves two different genes coding for height and flower color in pea plants. The alleles for tallness (D) and purple color (P) are dominant over the alleles for dwarfness (d) and white color (p) respectively.

According to this question, a tall plant with white flowers is crossed with a dwarf plant with purple flowers to produce the following proportion of offsprings: 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white.

Since some of the offsprings contain recessive alleles for both or either genes, the dominant traits of the parent is controlled by an heterozygous genotype. This means that the tall plant with white flowers has a genotype: Ddpp while the dwarf plant with purple flowers has the genotype: ddPp. In a cross between Ddpp × ddPp, 1/4 of each combination of alleles is produced in the offsprings (see punnet square in the attachment).

Water leaves the internal cavity of a sponge through the
Trava [24]

If I'm not mistaken, it leaves through the osculum which is a cavity located on the upper part of a sponge.

Sponges feed through a process called filtration, which means that they filter the water in search of nutrients. And after they collect everything they need from the water, they need to let it out somehow; through the osculum.



Hope it helped,
