Cell membrane not to sure about but cell wall was made by donald trump because you know how much he likes walls lol
anyway the cell membrane is selectively permible to ions
the cell wall dosent let anything by but is only found in plant cells
Answer:
Comparison between serine protease and aspartic protease
Both serine protease and aspartic protease are the hydrolytic enzymes play an important role in the digestion of protein molecules
Explanation:
Contrast betwwen serine protease and aspartate protease
Serine protaese contain serine amino acids in its active site or substrate binding site whereas Aspartic protease contain aspartic acid in its active site of substrate binding site.
Trypsin, chymotrypsin and elastase belongs to the family of serine protease Whereas pepsin,rennin belongs to the family of aspartic protease.
Answer:
False. The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere.
Explanation:
All the steps of GPCR signaling would be prevented in the presence of a beta-blocker drug.
<h3>What is Beta-blocker?</h3>
Beta-blocker may be defined as a kind of medication that chokes the activity of substances, such as adrenaline, on nerve cells and provokes blood vessels to relax and dilate.
Adrenergic receptors choke the attachment of catecholamine that is epinephrine to the G-protein. G-protein activates adenylyl cyclase which in turn activates protein kinase A.
But when the beta-blocker drug is subjected to this pathway, it blocks the attachment of the hormone to their receptors, hence none of the pathway or steps would be carried forward. This is because signaling is not initiated.
Therefore, all the steps of GPCR signaling would be prevented in the presence of a beta-blocker drug.

Explanation:
Patrick is a heterozygous dominant (he have one allele for pink body color and one allele for yellow body color
His wife Trisha is homozygous recessive (she have two alleles for yellow body color)
When they mate their is a 50% chance that the offspring will has the dominant allele from his father and a 50% chance that the offspring will has the recessive allele from his father and his phenotype will be his father allele in both cases
