Answer:
True.
Explanation:
Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.

An engineer made a model of a ship to help him think about how it works ha made sure that some characteristics of the ship were accurately represented but he did not include all of the ships characteristics in his model is it okay that he ignored some of the ships characteristics
Answer:
Yes it is ok
Explanation:
This usually depends on what the engineer is trying to accomplish or learn. For example, if the engineer is simply trying to understand how the architecture floats or cuts through the water then he does not need to model the engines or other unnecessary characteristics. On the other hand, if the engineer wants to understand how the engine provides power to the entire ship then he would need to model the engine and all the connected parts but not the outer exterior of the ship. Therefore, it is ok that he did not model the ship completely as long as it provides the information needed.

Water makes up a large percentage of the body’s cells. For a cell to remain in homeostasis, there must be a mechanism to control water changes in the cells. The movement of water from an area of high water concentration to an area of low water concentration is
A.Diffsion
B.stable transport
C.Active transport
D.Osmosis
Answer:
osmosis
Explanation:
on edge2020
The movement of water from an area of high water concentration to an area of low water concentration is called as Osmosis. Thus option D is correct.
What is osmosis ?The process in which solvent molecules pass from a lower concentration based solution to a higher concentration solution through a semipermeable membrane called as osmosis.
It is a passive process as no external energy is needed.
When a living plant cell kept in a sugar or salt solution, water diffuses from the cell sap out through the cell membrane called as ex-osmosis.
The cell causes shrinkage of the protoplasm due to water loss, where the cell undergo a condition called as plasmolysis or necrosis.
When the plasmolysed cell is placed in distilled water, the cell regains it’s turgidity and also the original shape and size by a process called endosmosis.
This condition is called deplasmolysis or cytolysis. Thus option D is correct.

why do plant need food
Answer:
They need food in order to gain the initial energy they need.
Explanation:
Plants unlike humans don't get food by primary sources (aka, hunting). instead they retrieve their food from the suns rays. Without the suns rays they are able to convert this energy into glucose for themselves, and will essentially die because they do not have that source of food to give them the energy they need to survive.

C)The spongy bones of the skull cause the ball to bounce off the head.
D)The joints in the skull move to prevent the football from hitting the head.
Answer:
B- The fused bones of the skull lessen the impact on the brain.
Explanation:
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.

The fused bones of the skull lessen the impact on the brain and help prevent injury to the brain.
What is the structure and function of the skull?
The skull consists of 22 bones in most adult specimens, and these bones come together via cranial sutures. The function of the skull is both structurally supportive and protective. The skull will harden and fuse through development to protect its inner contents: the cerebrum, cerebellum, brainstem, and orbits.
