Answer: A...Amber

Explanation:

Amber is a fossilized tree resin. The resin varies in color depending upon the tree species. It becomes hard after drying. It is used for making jewellery and ornaments. It is sometimes also consider as gemstone. It is called as fossilized resin because of the fact that the resin on being liquid traps insects, plant structures, annelids and frogs. On hardening the entire trapped material get preserved as a fossil.

On the basis of the above explanation, A. Amber is the correct option.

A. _____C6H1206+ ___02 ---> ___C02+___H20 + ___Energy (ATP)

Usimov [2.4K]

Answer:

C6H1206 + 6 O 2 ---> 6 CO 2 + 6 H 2 O + ATP

Explanation:

The reaction shown above is of cellular respiration. Cellular respiration can be described as a process bn which sugars such as glucose and oxygen are converted into carbon dioxide and water. Energy in the form of ATP is also released during this process. This energy is used by cells to carry out its normal functions like growth of a cell etc. The process of cellular respiration occurs in the mitochondria of a cell.

Answer:

S phase is called as DNA synthesis phase.

During G2 phase cell grow rapidly and protein is synthesized and cell prepares itself for mitosis.

During Mitotic (M) phase, cell division occur.

spermatogenesis is the process during which the production of male sperms occur.

In oogenesis the female egg is produced. Further explanation in attached figures.

Lactic acid fermentation can be modeled by which equation?

Reptile [31]

Lactic acid fermentation can be modeled by the following equation: Pyruvic acid + NADH → Lactic acid + NAD+

LACTIC ACID FERMENTATION:

Fermentation is a process undergone by some anaerobic organisms. Ideally, the process of cellular respiration proceeds as follows in the presence of oxygen: Glycolysis- Kreb cycle - ETC.

However, in the absence of oxygen (anaerobic condition), the product of glycolysis which is pyruvic acid combines with an electron carrier (NADH) to give rise to lactic acid and NAD+.

This means that pyruvic acid is reduced while NADH is oxidized as modelled in the following equation:

Pyruvic acid + NADH → Lactic acid + NAD+

What do you do when your in deep love with someone but in a relationship with another person who loves you the same way as you l

Simora [160]

Oh sweetheart. Leave the person if you're clearly not in love with them as they are with you. You're only hurting yourself, and that other person. They deserve someone who loves them as much as they love. And so do you! Be with whom you love, and set that other person free. Yes its not going to be easy, but life isn't easy. That's just part of life and growing up.
