Someone can please describe what happens to the valence electrons when two elements form an ionic compound?

Answers

Answer 1

Answer:

ionic bond / electrovalent bond.

electrostatic attractions between oppositely charged ions .

eg: NaCl.

Na - 2, 8 ,1 Na^+ 2, 8

Cl - 2, 8 ,7 Cl^- 2 , 8, 8

Na^+ + Cl^- gives Na^+Cl^-

sodium loses one electron to attain nearest noble gas configuration.

Chlorine gain one electron from sodium to attain nearest noble gas configuration .

This organelle modifies and labels proteins so they will be working properly and arrive at the correct destinations? so whats the answer?

Answers

Answer:

[tex]\boxed {\tt Golgi \ apparatus}[/tex]

Explanation:

After a protein is produced on a ribosome it is sent to the endoplasmic reticulum. Here, proteins fold and then are sent to the golgi apparatus.

In this organelle, proteins are modified and labeled. Sugar groups (modifications ) and tags/signals (labels) can be added. From the golgi apparatus they are sent to different destinations or secreted.

So, the correct answer is Golgi apparatus.

Golgi apparatus

The Golgi apparatus, which is usually situated near the nucleus, receives proteins and lipids from the ER, modifies them, and then dispatches them to other destinations in the cell. Transport from the ER to the Golgi apparatus—and the Golgi can either move onward through the Golgi stack or, if they contain an ER retention signal, be returned to the ER; proteins exiting from the Golgi are sorted according to whether they are destined for lysosomes (via endosomes) or for the cell surface.

genetic diversity
small population

Answers

Small population is the answer

Your welcome

According to the Charles darwin theory of natural selection, genetic diversity best allow a species to survive environmental changes.

What is the theory of natural selection?

Natural selection is the procedure via which populations of living organisms acclimate and modify.

Individuals in a population are naturally variable, indicating that they are all distinct in some manner. This divergence means that some individuals have characteristics better suited to the environment than others.

Natural selection leads to evolution.

Thus, genetic diversity best allow a species to survive environmental changes.

Under certain external conditions, a person will perspire a great deal. For which internal condition does this response
primarily provide homeostasis?
water balance
electrolyte balance
temperature balance
energy balance

Answers

Answer:

Perspiration provides homeostasis to the internal condition of temperature balance.

Explanation:

Perspiration occurs as a consequence of the increase in environmental temperature, which at the same time produces an increase in body temperature.

The high body temperature produces a stimulus that reaches the thermoregulation center of the central nervous system, which produces a response transmitted through the sympathetic nervous system, causing the sweat glands to increase the production of sweat.

The sweat that covers the skin is capable of acting as a physical agent to lower the temperature, a mechanism of thermal regulation that contributes to temperature balance.

The other options are not correct because:

Water and electrolyte balance is done at the renal level. The energy balance depends on the food intake and the amount of energy used.

Answer:

temperature balance
