Openings between _____ cells create pores in the leaf epidermis that play a critical role in photosynthesis by allowing diffusio

n of atmospheric CO2 into a leaf's interior.

Answer:

Guard

Explanation:

The opening between guard (pores) cells is known as stomata. The stomata helps in diffusion of atmospheric CO2 into leaf's interior and also involved in loss of water by plant leaves through transpiration. The opening and closing of stomata is controlled by guard cells.

Guard cells control the opening and closing of stomata by becoming turgid or flaccid because of potassium ions. The water potential decreases by increasing the solute concentration and water always flow from higher potential to lower potential. Remember maximum water potential is zero.

When potassium ions concentration increases inside the guard cells, water follow the potassium ions and guard cells become turgid which cause the opening of stomata. On the other side when the potassium ions concentration decreases inside the guard cells the water leaves the guard cells and guard cells become flaccid causing closing of stomata.

Name and describe all of the weather fronts.
Yakvenalex [24]

Answer:

four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.

a air front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity.

A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. ... Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.

Stationary Front - a front between warm and cold air masses that is moving very slowly or not at all.

Occluded Front - a composite of two fronts, formed as a cold front overtakes a warm

Sand that extends from a coast into open water is called a barrier spit. <br> a. True <br> b. False
AysviL [449]
<span>It is True - Sand that extends from a coast into open water is called a barrier spit.

Barrier spits are formed when there is a deposit on the shoreline due to the lateral movement of water.

The waves are known to hit the shoreline at a particular angle which cause the lateral movement of water accompanied with the sedimentation along the coastline in the direction of the wave motion.</span>

ad-work [718]

(D) Most of the best sites are inaccessible by land transportation, so making roads to them is often prohibitively expensive.

<h3>What is a Reserve?</h3>

A nature reserve, also referred to as a wildlife refuge, a wildlife sanctuary, a biosphere reserve or bioreserve, a natural or nature preserve, or a nature conservation area, is a protected area that is important for its flora, fauna, or features of geological or other special interest. It is reserved and managed for conservation efforts as well as to offer unique opportunities for study and research.

In some nations, government agencies may designate them, as well as private landowners like charities and research facilities. Depending on the level of protection provided by local regulations, nature reserves are classified into various IUCN categories. It is typically subject to stricter protection than a natural park. In laws and official documents, different jurisdictions may use different wording, such as ecological protection area or private protected area.
