The answer is C

Explanation:

Mark the brainly

Answer 2

Answer:

A. It loses an electron

Explanation:

An atom becomes a positive ion when it loses an electron (then there are more protons than electrons in the atom) when it is trying to reach stability. This is called a Cation. The opposite of this is an Anion, when an atom gains an electron to reach stability and becomes a negative ion (because the number of electrons are higher than the number of protons).

Which would conserve more energy if all humans ate only vegetables or ate only meat

Answers

Answer:

There would be more conservation of energy if human beings it only meat.  

Explanation:

this is because meat consists of a significant portion of the fat. The amount of of energy that is liberated per molecule of fat is almost twice the amount of energy that is liberated by carbohydrate or protein. As a result of this the total energy consumption will be more if human being consumes only fat. however it takes more time to digest fat as compared to that of carbohydrate and protein.

Answers

However, the strong evaporation and tidal forces they experience often lead to their fragmentation.

According to the model of the human respiratory system, how do structures in the
respiratory system interact to protect the lungs? How might a sinus infection affect the
rest of the respiratory system?

Answers

Answer: The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

Explanation:

There are Cilia that protect the airways of the lungs from invaders and pathogens by trapping them. Sinus is present in the nose which blocks the airways while it swells.

What is the respiratory system?

The respiratory system is the system that is responsible for getting oxygen into the body and removing carbon dioxide from the body.

Together, the respiratory and circulatory systems move blood and oxygen throughout the body. The trachea, bronchi, and bronchioles are the pathways by which air enters and exits the lungs. The pulmonary arteries and veins, which attach to the heart, carry blood into and out of the lungs.

Thus, there are cilia that, by trapping invaders and diseases, defend the lungs' airways. The nose has a sinus, which obstructs the airways when it grows.

Answers

Answer:

I'm pretty sure the answer is D.) Less Dense

Explanation:

Answer:

d) less dense

Explanation:

When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.
