Biology

Monica [59]2 years ago

Answer:

Oocyte refers to the female germ cell which is involved in the process of reproduction.  

In humans, the primary oocyte is diploid in nature, that is, it contains 46 chromosomes as it is formed by mitotic divisions of the oogonium.

In contrast, secondary oocyte is haploid in nature, that is, it contains only 23 chromosomes as it is formed from primary oocyte after it has completed its meiosis I.

Secondary oocyte then undergoes meiosis II to produce a mature ovum.

Give the role of air in an ecosystem
Radda [10]

Sustain Life and Growth

Air consists one of the main life-sustaining gas called oxygen. Almost all living things breathe in and breathe out this air. Nitrogen and Carbon dioxide are also other gases that are vital for plants and their growth.

Combustion

Apart from this, air supports burning or combustion. The oxygen present in air help in burning of the fuels to basically carry out activities like cooking food, running industries and vehicles as well as generating heat and electricity.

Temperature Control

Another important aspect of air is that it helps in maintaining the temperature on the earth surface by circulating hot and cold air. Air acts as a conductor of heat as well. Even phenomena such as water cycle are dependent on air.

Supplier of Energy

Air which consists of energy is one of the main suppliers of energy. Living things are made up of cells and these cells extract oxygen within the blood to produce energy usually in the form of ATP. This biochemical generation of ATP is essential to maintain life on the earth.

Photosynthesis

Carbon dioxide, which is a component of air is used by plants during the process of photosynthesis. Here oxygen is also released by plants. And we already know how vital oxygen is.
