What is the first step in triggering a change in membrane potential?

Biology

Sophie [7]3 years ago

Answer:

The membrane potential is maintained in the cell due to the unequal distribution of the ions inside and outside of the cell. This membrane potential is important for the conduction of the nerve impulse.

The arrival of the stimulus triggers the action potential. The resting membrane potential is -70mV. This is maintained by the presence of potassium ions. The influx of the sodium ions result in the change in the membrane potential from -70mV to +30mV.

Well, you don't specify the parent traits, so I'll just do one for each...

If both parents are homozygous RR, then all 60 of the babies will be black

If both parents are homozygous WW, then all 60 of the babies will be white 

If both parents are heterozygous RW, then there will be 15 black babies, 15 white babies, and 30 spotted babies. 

If one parent is homozygous RR and one is homozygous WW, then all of the babies will be spotted

If one parent is homozygous RR and one is heterozygous RW, then 30 of the babies will be black, and 30 will be spotted

If one parent is homozygous WW and one is heterozygous RW, then 30 of the babies will be white, and 30 will be spotted.

Trematodes are acoelomates that have effective defenses against attack by their hosts' immune system.

Trematodes are flatworms, internal parasites known as flukes. Their life cycle is complex: they sexually reproduce in vertebrates and asexual reproduce in mollusks (mostly snail). The body of flukes is covered with tough tegument that defends them form digestive enzymes of host’s intestine.

Cnidarians are diploblasts that produce complex, capsule-like organelles.

Cnidaria are water organisms with simple structure: two layers of epithelium and a jelly substance between them. The cells of Cnidaria-cnidocytes contain capsule with venom substance in it with protective role.

LekaFEV [45]

Answer;

-Nuclei acid

Explanation;

-Nucleic acids are molecules that allow organisms to transfer genetic information from one generation to the next. These macromolecules store the genetic information that determines traits and makes protein synthesis possible.

-Nucleic acids include DNA and RNA. These molecules are composed of long strands of nucleotides. Nucleotides are composed of a nitrogenous base, a five-carbon sugar, and a phosphate group.
