Answer:
It allows water and other molecules to enter and exit the system.
Explanation:
Plants have both a cell membrane and a cell wall. These allow needed molecules, such as water, to enter the cell. Both the cell wall and the cell membrane are semi permeable, which means that they choose what can enter and leave the cell. Molecules like water and other useful things to the cell enter it, and things such as waste leave the cell through the membrane and wall.
Remember that only plant cells have cell walls. Animal cells only have a cell membrane. But both the wall and membrane have the same purpose.
Answer:
Nervous System
Explanation:
"Muscle contraction begins when the nervous system generates a signal. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron."
If the number of blue jays increases, the two likely effects on other populations are both the number of mice and the number of caterpillars will decrease.
<h3>What are two likely effects on other populations due to the increment in Blue jays population?</h3>
- An organism that preys on other species in order to consume them as food is referred to as a predator.
- Prey is a term used to describe an organism that a predator kills.
- An ecosystem's ability to balance an expanding prey population depends on the interaction between predators and their prey.
- Blue jays and crows both rely on mice and caterpillars as food sources, as indicated by the current circumstance.
- Mice, caterpillars, and blue jays are the prey, while crows and crows are the predators. The two prey populations will decline if the number of blue jays rises.
Hence, both the number of mice and the number of caterpillars will likely drop as the number of blue jays rises, having two possible implications on other populations.

All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity. Homeostasis is necessary for normal life processes that take place inside cells.
