Answer:
The roots suck up the water in the ground. Then transfer it to the plant.
Explanation:
Answer:
<u>d. Transport proteins within the membrane serve as a tunnel for molecules to enter the cell.
</u>
<u />
Explanation:
Solutes are typically moved across the cell through either passive or active transport. The cells, surrounded by a bilipid layer or plasma membrane is amphiphlic- its polar, hydrophilic lipid heads face outwards, while their non-polar hydrophobic lipid tails face inwards towards each other.
While lipid-soluble molecules move across the layer easily, it is also difficult for charged and also large molecules to move across its surface, into the cell. Transmembrane channels, <u>embedded within the membrane</u>, help to maintain selective permeability as transport proteins, pores and gated channels. Simple diffusion happens as a method of passive transport in cells through plasma membranes.
The solutes travel through the plasma membrane in the process of diffusion from regions of high concentration to regions of low concentration; this occurs without the use of energy. <u>Molecules moving against their concentration require active transport mechanism to cross the membrane</u>.
The last option is the most accurate

Answer: what is the major environmental factor limiting the number of autotrophs at great. Which abiotic factor has the least effect on the ability of aerobic organisms to live and, all living things that directly or indirectly affect the environment are known as. Which statement about the release of chemicals by willow trees is correct?
Explanation:
Answer:
The correct answer is - negative feedback loop.
Explanation:
A negative feedback loop takes place in the biology when the end product of a particular reaction leads to decrease in the reaction. A negative feedback loop makes system to bring the homeostasis.
Negative feedback loops takes place inside the body of an individual to decrease the function of a particular reaction, it prepared the body for the change that occur in the atmosphere such as pH, temperature and other.
Thus, the correct answer is - negative feedback loop.
