Sauron [17]

Answer:

b) from a region of high pressure to a region of low pressure

Explanation:

Blood flow is measured in blood volume per unit time. It is the movement of blood through an organ, tissue or vessel. It is initiated when ventricles in heart contract leading to its ejection at high pressure. Major arteries receive this blood and they further transport it at high pressure to smaller arteries, arterioles and capillaries. Hence arteries have thick walls to withstand this pressure. The pressure decreases when blood reaches to veins hence their walls are not that thick.  Hence, blood flows from a region of high pressure to a region of low pressure.

What set of characteristics do living organisms such as birds, trees, and bacteria have that distinguish them from nonliving thi
Sergio [31]
The 7 (sometimes 8) characteristics of life are:
1. living things are composed of cells
2. living things have different levels of organization
3. living things metabolize (i.e. use energy)
4. living things respond to their environment
5. living things grow
6. living things reproduce
7. living things adapt to their environment
(some sources include) 8. living things have genetic material

Viruses do not metabolize, they do not grow, they do not adapt to their environment, and they cannot reproduce independently; viruses require host cells to reproduce and perform the other functions that give them the appearance of aliveness.

Answer:

(A) rate=

Sp

Ss

st

Explanation:

The rate of chemical is a measure of the speed of a chemical reaction.

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.

Reaction rate is usually expressed in terms of a change in concentration of the chosen reactant or product per unit of time.

During a reaction, the concentration of the reactant decreases exponentially with time while that of a product increases exponentially with time.

Reaction rate  = \frac{change  in concentration of a reactant/product}{Time taken}
