Large molecules such as hormones materials are expelled from cells during exocytosis

Explanation:

The materials inside the cells are transferred to the outside of the cell and this manner is termed as Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.

For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.

emmainna [20.7K]

Answer:

Reduction of sulfur compounds and the release of hydrogen sulfide is happening here.

Explanation:

Sulfur is an important element in the sulfur cycle. Sulfur compounds can be found on earth in various forms. They can be found in mineral rocks and organic matter. It is the work of bacteria to reduce sulfur compounds and convert them to sulfides.

There are different types of bacteria that reduce various sulfur containing compounds. They are sulfate-reducing bacteria, sulfur-reducing bacteria, sulfite reducing bacteria etc. In a swamp there is low oxygen availability and organic matter decays in this condition.

The sulfate reducing bacteria oxidizes the organic matter and releases Hydrogen sulfide.

Considering the Mendelian traits tall (D) versus dwarf (d) and violet (W) versus white (w), consider the crosses below and deter

Artyom0805 [142]

Answer:

DDWw x Ddww

DdWw x DDww

DDWw x DDww

Explanation:

D for tallness

d for dwarfness

W for violet

w for white

For Parental Plants that has

tall, violet x tall, white

The representation will be

DDWW × DDww (We the apply the mendelian crossing)

This will yield offsprings with the following trait

DDDD × DwDw

DWDW x WwWw

DdWw x ddww

Ddww x ddWw

DdWw x DdWw

DDWw x ddww

From the above Offsprings

1/2 tall, white and 1/2 tall, violets offspring are

DDWw x Ddww

DdWw x DDww

DDWw x DDww
