When carbon dioxide is formed, one carbon atom forms double covalent bonds with two oxygen atoms. Carbon dioxide is considered

8 0

Carbon dioxide is considered more stable than individual atoms as now the outer energy levels of all atoms are filled. Covalent bonds involve the sharing of electrons, and all bonds form in order to achieve more stability. The overall molecule will be more stable than the individual atoms. No atoms will bond together to become less stable.

Carbon dioxide is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.

Sperm move to the uterine tube through uterine contractions and the energy of their own flagella. what other factor is involved

nadya68 [22]

In the movement of sperm tail plays an important role due to which sperm is able to move.

Sperm move to the uterine tube through uterine contractions and the energy of their own flagella.

Motility of sperm is also depend upon various metabolic pathways and the mechanism of regulation.

<h3>What is causes sperm to move?</h3>

The structure of sperm contains tail which have large numbers of protons channels which are known as Hv1 channels that respond to changes in pH and concentration of zinc outside the cell.

the human is able regulate blood sugar levels within a fairly specific range, even high amounts of carbohydrates are consumed

Stells [14]

Question options:

1. Homeostasis

2. Digestion

3. Embryology

4. Cellular respiration

Answer:

1. Homeostasis

Explanation:

Sugar level in humans is regulated by "Insulin" and "glucagon" hormones that are secreted by the pancreas. Both hormones work in a balanced way to regulate the blood sugar level within a specific range if the sugar levels spike or drop.

Together, insulin and glucagon help maintain a state known as homeostasis. By definition, homeostasis is the maintenance of the internal environment of cell/body with respect to the external environment. Thus, homeostasis maintains a relatively stable state that persists despite changes in the world outside. When blood sugar is too high, the pancreas secretes more insulin which acts to trigger breakdown of sugar thus reducing its level. By contrast, when blood sugar levels drop, the pancreas releases glucagon to allow conversion of macromolecules to simple sugars and raise its level.

The stage of mitosis where the chromosomes line up

schepotkina [342]

Answer:

Metaphase

Explanation:

Chromosomes line up at the metaphase plate, under strain from the mitotic shaft. The two sister chromatids of every chromosome are caught by microtubules from inverse shaft posts. In metaphase, the shaft has caught every one of the chromosomes and arranged them at the center of the cell, prepared to separate.
