What is the effect of ph and temperature on an enzyme

1 answer:

7 0

Enzymes are affected by the pH and temperature of their environment. For instance, stomach enzymes are meant to function in highly acidic environments. However, other enzymes have different functions, and may thrive in a lower pH. When an enzyme is exposed to a much higher or lower pH than they are made to function at, they become denatured. The same is with temperature. Exposing an enzyme to high temperature can denature it too. Hope this helps! :)

Why are viruses considered as peculiar microorganisms? Plese answers

Aleksandr [31]

Answer:

Because they can only reproduce in a living cell

Explanation:

Virus is an organism that is incapable of replicating on its own without a living host. A virus infects a living host and makes use of Its replicational ability to produce new virions. A virus consists of a genetic material surrounded by a Protein called CAPSID. It does not possess the characteristics of other living organisms.

This means that it does not carry out any of the features a living cell undergoes e.g reproduction, respiration etc. Due to this reason, it is not classified as a living thing. They don't possess organnelles that carry out this peculiar functions.

A geneticist crossed pure breeding black mice with pure breeding brown mice. All the 992 mice in the F1 generation had black coa

uysha [10]

Answer:

C. An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele

Explanation:

Assuming the black genotype is BB and the brown genotype is bb.

At F1:

BB x bb = All Bb (black)

At F2:

Bb x Bb = BB (black), 2Bb (Black), bb (brown)

Th ratio of black to brown is 3:1

961 black : 317 brown is approximately 3:1.

Hence, the correct option is C.

An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele
