Answer:
the generic effect most likely causes each leaf to lack a sufficient root system that can support the plant's growth
when an animal is thirsty, it responds by drinking water
Answer:
<u>d. Transport proteins within the membrane serve as a tunnel for molecules to enter the cell.
</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>.
Answer: Functionally, DNA maintains the protein-encoding information, whereas RNA uses the information to enable the cell to synthesize the particular protein. 1 Differences between DNA and RNA: DNA stores the genetic information, whereas RNA uses the information to help the cell produces the protein.
Explanation:
the answer is the beetle is neither harmed nor helped by the mite.
