Answer:
The endodermis is the central, innermost layer of cortex in land plants.The endodermis helps regulate the movement of water, ions and hormones into and out of the vascular system. It may also store starch, be involved in perception of gravity and protect the plant against toxins moving into the vascular system.
Answer:
According to collision- coalescence theory, formation of raindrop from cloud droplets occurs when cloud droplets collide and coalesce or stick together.
Explanation:
- The only significant difference between a raindrop and a cloud droplet is that a raindrop consist of a velocity that is non-negligible during the fall.
- Larger droplets having higher terminal velocities fall faster and collide with smaller droplets. Often the cloud droplets stick together and coalesce to form a larger droplet.
- This starts a chain reaction where these bigger droplets fall even rapidly, collide with the other droplets in their path and merge with these droplets.

Active transport uses energy and passive transport does not
<h3><u>Explanation</u>;</h3>
- <u>Passive transport occurs when materials move across cell membranes without using cell energy (ATP). </u> Examples of passive transport include; diffusion, facilitated diffusion, and osmosis. It moves small molecules like water, oxygen, carbon dioxide and glucose.
- <em><u>Active transport on the other hand involves the movement of materials across the cell membrane that requires the use of cell energy (ATP)</u></em>.
- In other words the difference between active transport and passive transport is that passive Transport moves ions from high concentration to low, using no metabolic energy while active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.
Photosynthetic organisms capture energy from sunlight with pigments.
Answer and Explanation:
Many elements can be responsible for this, among them, we can mention the presence and absence of predators in the different places on the rocky coast. This is because predators can influence not only the number of organisms found, but also the types of organisms.
Another element that may be the cause of this variability is the availability of resources necessary for the life of these organisms, in addition, the impact of the waves on the rocks, can cause the variability of the organisms, since some may not be able to resist the impact of the waves.
