Answer:

A. Carbon dioxide moves in; oxygen moves out

Explanation:

<em>Stomata are small pores on the leaves of green plants whose opening and closing is regulated by the surrounding guard cells.</em>

During the day, solutes from surrounding cells enter the guard cells leading to reduction in the water potential of the cells. Consequently, water enters the guard cells and makes them turgid, leading to the opening of the stomatal pores.

At nights, the solutes in the guard cells move back to the surrounding cells, leading to loss of water and flaccidity of the cells. The guard cells collapse against one another, leading to the closure of the stomatal pores.

When stomata opens, carbon dioxide diffuses in and it becomes utilized in the process of photosynthesis. The resulting oxygen from photosynthesis then diffuses out through the stomatal pores.

Answer:

Carbon dioxide moves in; oxygen moves out

Explanation:

The pigment that offers the green pigmentation for green plants is known as Chlorophyll. On the surface of the leaves on green plants are microscopic openings known as Stomata in the epidermis of leaves. Stomata are generally more numerous on the underside of leaves. They provide for the exchange of gases between the outside air and the branched system of interconnecting air canals within the leaf.

On a sunny day, The concentration of carbon dioxide in the air is a regulator of stomata opening in many plants. The stomata opens (then  Carbon dioxide moves in and in-turn releases oxygen after photosynthetic activities has taken place) and closes in response to the internal pressure of two sausage-shaped guard cells that surround it. The inner wall of a guard cell is thicker than the outer wall.

The main function of these Guard cells  are to control excessive water loss, closing on hot, dry, or windy days and opening when conditions are more favourable for gas exchange.

Why do you think scientists want to be able to forecast space weather?
DiKsa [7]

Answer:

Scientists would most likely want to forecast space weather in order to know if it is safe for not only to lift off into outer space, but to be able to help astronauts in any case of emergency if something were to happen in the future.

Such as debris of small rocks that could pass by, so then astronauts would have to stay in the shuttle. To be protected from it.

In any case, scientists want to forecast the weather in outer space in order to protect astronauts, from any incoming dangers.

krok68 [10]

On which structure would you expect to find a body map?

a. frontal lobe

b. temporal lobe

c. occipital lobe

d. thalamus

e. brain stem</p>

Frontal lobe  expect to find a body map.

a. frontal lobe

<u>Explanation:</u>

The frontal projection is the piece of the cerebrum that controls significant. The correct side of the equator of the frontal projection controls the left piece of the body and the other way around. This can decide how the body is influenced by mind damage.

The frontal projections are viewed as our enthusiastic control focus and home to our character. There is no other piece of the cerebrum where sores can cause such a wide assortment of side effects (Kolb and Wishaw, 1990).

The frontal projections are engaged with engine work, critical thinking, immediacy, memory, language, inception, judgment, drive control, and social and sexual conduct.
