Lemur [1.5K]

Answer: Water diffuses into the skin via sweat ducts which alters the electrolyte balance. electrolytes can be salts like sodium and potassium. This alters the stability of neurons causing blood vessels to constrict therefore decreasing the amount of fluid in the fingers which would normally give the skin tension. The decrease causes wrinkles.

Explanation: I had that answer before and it was really hard to understand it, I hope this helps you. Best Of Luck!

3) identify and describe three abiotic characteristics of ecosystems. Give an example of how each
HACTEHA [7]

Answer:

The abiotic characteristics of an ecosystem that affects man includes: Land surface, rainfall and relative humidity.

Explanation:

In the ecosystem, man occupies the terrestrial habitat which is affected by the abiotic factors listed above.

Abiotic (non- living) factors determine the type of biotic (living) community that is found in an ecosystem. These factors include Land surface, rainfall and relative humidity, just to mention a few.

--> LAND SURFACE: This is responsible for the marked variation in the vegetation of a place. For example, a mountain in the tropics may have a rain forest vegetation at it's base and an afroalpine vegetation near its peak. The gradient of the slope affects the growth of organisms. A steep slope encourage fast run - off of water and therefore encourages erosion, which results in shallow and infertile soil. This in turn AFFECT man's farming activities as there would be little to no crop yield.

--> RAINFALL: Water is a very important abiotic factor that affects life. The main source of water to terrestrial habitat is rainfall. When rain falls, a greater percentage of it sinks into the soil while the rest run- off into water bodies. Water is absorbed by root hairs into the plant and used for photosynthesis to produce food. The absence of rainfall in the environment of man could lead to drought which AFFECTS man negatively.

--> RELATIVE HUMIDITY: This is a measure of the amount of moisture in the atmosphere. It's usually high in hot wet regions. It affects the rate at which water evaporates from the body surfaces of organisms. Low relative humidity cause more water (sweat) to evaporate from body surfaces giving the human body a cooling effect. But in high relative humidity, the sweat cannot evaporate leaving the body feeling hot and sticky. This AFFECTS man as the body tries to cool off in a harder way by increasing rate of respiration and depth of blood circulation.

Nina [5.8K]

Answer:

C, a long absolute refractory period.

Explanation:

Tetanus is not possible in cardiac muscle tissue because cardiac cells have longer action potentials and a very long refractory period compared to other cells. This helps prevent the heart from cramping and seizing up.

Len [333]

The correct answer is he's screwed because with enough training in a mock scanner, the fMRI is sure to work.

The FBI kidnapped Mike and put him in an fMRI machine to track whether he was lying or not. FBI detects lies from the flow of blood. when he is lying, his brain put more efforts and more flow of blood.

fMRI detects lies according to brain activation patterns. Its brain activation patterns shoed different from the person who is innocent.

The flow of blood in activated areas helps in tracking lies using an fMRI machine. So, during the lie detection areas highlighted if a person lies.

By leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent ____________________.
shusha [124]

Answer:

Soil erosion.

Explanation:

No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.

Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.

Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.
