What is not a contribution of the cardiovascular system to other body systems?
Vinvika [58]

OPTIONS:

a) Blood delivers calcium and phosphate ions that are needed for building bone extracellular matrix.

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

c) Blood carries newly absorbed nutrients and water to the liver.

d) Blood circulates cells and chemicals that carry out immune functions.

e) Blood delivers clotting factors and WBCs that aid in hemostasis when skin is damaged

Answer:

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

Explanation:

Options a, c, d, e are all true statements about the contributions of the cardiovascular system to other body systems except option b which states that “Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs”.  

Actually, the cardiovascular system works together with the respiratory system to supply oxygen to body tissues as blood is circulated in the body, while carbon dioxide is removed from the body at the lungs. <em>In order words, carbon dioxide is removed, while oxygen is picked up as blood is transported through the capillaries of the lungs. </em>

Not all intercellular signals require transduction. Which one of the following signals would be processed without transduction?
Musya8 [376]

Answer:

The correct answer would be a lipid-soluble signal.

Signal transduction refers to the set or cascade of bio-chemical reactions take place in a cell in order to transmit the chemical or physical signal from outside the cell to inside target molecule.

It is usually initiated by receptors present on the membrane of the cell which sense the extracellular stimulus (such as ligand, hormone, pressure, temperature, pressure etc). Once activated, these receptors activate the cascade of reaction which ultimately reaches the target molecule and produces a cell's response.

In contrast, the lipid-soluble signals (such as steroidal hormones, thyroid hormone etc) enter the cell membrane without any hindrance. They directly bind to intra-cellular receptor present in the cytoplasm or on the nuclear membrane.

The hormone-receptor complex then enters the nucleus and act as transcription factor and produces the response in the form of transcription.

What errors exist in the table below?
Vera_Pavlovna [14]

Answer:

A. spiral galaxies are not pinwheel-shaped

Explanation:

There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.

Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.

Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a  pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.

Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.

Hence, the error is foudn in first sentence, where it says that spiral galaxies are not pinwheel shaped. so teh correct option is A.
