There are two classes of membrane transport proteins—carriers<span> and </span>channels<span>. Both form continuous </span>protein<span> pathways across the lipid bilayer. Whereas transport by </span>carriers<span> can be either active or passive, solute flow through </span>channel proteins<span> is always passive.</span>
Answer:
Daphnia is an ideal system for studying multiple stressors because of its short generation time, well-studied ecology and evolutionary history, wide geographical distribution across many limnetic systems, high mutation and recombination rates, high sensitivity to changes in environmental conditions, unique cyclical
Explanation:
A diploid cell is a cell that contains two sets of chromosomes. Each
chromosome pair is considered to be one set of homologous
chromosomes. ... Gametes are haploid cells . During sexual
reproduction, gametes (sperm and egg cells ) fuse at fertilization to
form a diploid zygote.
Answer:
Passive Transport
Explanation:
The movement of molecules from an area of High concentration to an area of lower concentration in a living cell is called Passive Transport.
Passive Transport does not require energy input.
An example is Diffusion.
B would be your answer hope this helps :)
