Viefleur [7K]

Answer:

Protein K is a protein that can available in the human cell nucleus that binds to pre-messenger RNA as a part of heterogenous ribonucleoprotein. IgG is one of the five isotypes of immunoglobulin or antibodies.it is the most common antibodies in the blood circulation and makes the 75% of total antibody.

When you heat solution, generally protein k activity increase with an increase in the heat but up to an extent or point called optimum temp. The optimal temperature for activity ranges between 50-65°c. When an increase in temperature help with protein unfolding easing the ability for protein k to break down those proteins.

Darwin hypothesized that favorable traits spread through as species as
kompoz [17]
It wasn't that the favourable traits were passed down through generations of species, it's that natural selection removed the species who simply couldn't survive. Here's an example: There are two species of moth in a forest, one is brown and the other is black. The trees in the area have trunks that are brown like the moth's wings, so it can camouflage very well compared to the black moths. Eventually, more black moths were being eaten by various amphibians and bugs than brown moths. So, the favourable trait of brown wings continued to be passed on, whereas the black wings went extinct as they were all eaten. Hope that helped :D
