Answer:
deoxygenated blood is pumped back to the heart with the superior vena cava and inferior vena cava. Blood is then in the right atrium then it is pushed to the right ventricle in the heart. it is the pumped through the pulmonary artery to the lungs(the pulmonary artery is the only artery that carries deoxygenated blood). In the lungs blood is pumped to the cappilleries in the bronchus where oxygen in the air is passed through to the blood with heamoglobin and thus now the blood is oxygenated. The blood is the pumped brought back to the heart with the pulmonary vein(the pulmonary vein is the only vein to carry oxygenated blood).It flows into the left atrium where it is then pushed down into the left ventricle and is then pumped up through the aorta to the whole body.

why it is important to base scientific theories and models on empirical evidence as opposed to other ways of knowing such as religion
Answer:

The concentration of sodium on the inside of the cell is 20 mM. The outside of the cell has a sodium concentration of 115 mM. Which mechanism of ion uptake would best move sodium from the inside of the cell to the outside? osmosis diffusion passive transport active transport.
Answer:
It's active transport
Explanation:
The mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.
What do you mean by Ion uptake?Ion uptake may be defined as the process of movement of ions from one side of the membrane to the other.
Active transport helps in the movement of ions against the concentration gradient. It also requires energy. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.
Therefore, the mechanism of ion uptake that would best move sodium from the inside of the cell to the outside is active transport.

Answer:
They are modified by shape, function, or size. They are made to have certain roles in different parts of our bodies. These cells group together to make/form tissues. Then these tissues make up organs that we obviously need. Different specialized cells include blood cells, nerve cells, and reproductive cells.

A piano player uses her hands for brief quick movements. Which muscle fiber type would you therefore predict to be predominant in these muscles
For brief quick movements, which muscle fiber type would you therefore predict to be predominant in these muscles...Fast twitch muscle fiber type.
There are three types of muscle tissue. 1. Cardiac 2. Smooth 3. skeletal muscles. The skeletal muscle are involved in voluntary movements of the body.
Since the player uses her hand in a voluntary way of movement, therefore she makes use of her skeletal muscles.
With regards to the skeletal muscles, there are two types with regards to speed, we have the slow twitch and the fast-twitch.
The fast-twitch muscle fiber aids in fast movement of the body but for shorter periods compared to the slow twitch.

why is mechanical digestion of food important?? please help I only need one reason marking brainliest btw
Answer:
it makes the food smaller
Explanation:
Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.
