oogenesis

In the human female reproductive system, growth process in which the primary egg cell (or ovum) becomes a mature ovum. In any one human generation, the egg’s development starts before the female that carries it is even born; 8 to 20 weeks after the fetus has started to grow, cells that are to become mature ova have been multiplying, and by the time that the female is born, all of the egg cells that the ovaries will release during the active reproductive years of the female are already present in the ovaries. These cells, known as the primary ova, number around 400,000. The primary ova remain dormant until just prior to ovulation when an egg is released from the ovary. Some egg cells may not mature for 40 years; others degenerate and never mature.

The option that best illustrates the similarity and difference in the elemental makeup of these molecules is that carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements. That is option B.

Carbohydrates are macromolecule found is food substances that plays a vital role of energy supply to the body.

It is made up of chemical elements such as carbon,hydrogen and oxygen in the ratio of 1:2:1.

Lipid is another macromolecule found in food which is an energy reserve for the body.

Lipids are made up of elements seen in carbohydrates such as carbon, hydrogen and oxygen but contain many more hydrogen atoms than oxygen atoms.

Proteins are another type of macromolecule found in food which helps in body building and repair of worn out tissues.

Proteins are made up of elements seen in carbohydrates and lipids with the addition of nitrogen atom.

Therefore, carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements.

What are the 3 stages of photosynthesis?

Dmitry_Shevchenko [17]

STEP ONE: Harvesting Radiant Energy
The first step of photosynthesis occurs in the chloroplasts of plant cells. Light photons are absorbed by a pigment called chlorophyll, which is abundant in the thylakoid membrane of each chloroplast. Chlorophyll appears green to the eye because it does not absorb green waves on the light spectrum. It reflects them instead, so that’s the color you see.
STAGE 2: Converting Radiant Energy
After radiant energy from sunlight is absorbed, the plant converts light energy into a usable form of chemical energy to fuel the plant’s cells
STAGE 3: Storing Radiant Energy
The last stage of the photosynthesis process is known as the Calvin-Benson cycle, in which the plant uses atmospheric carbon dioxide and water from soil to convert ATP and NADPH. The chemical reactions that make up the Calvin-Benson cycle occur in the stroma of the chloroplast.
