Hey, i don’t see the diagram if you repost the question i will be able to help
Answer:
The answer to your question is: letter C
Explanation:
From the graph, we can conclude that catalase has a low activity at low temperatures. Activity increases a little at 30°C and this process is the highest at 40°C, after this temperature, activity disminishes again.
Options:
A. This option is wrong because the number of bubbles at this temperatures is low, maybe the enzyme is already denatured.
B. This answer is wrong, at 30°C the enzyme shows a low activity.
C. This answer is correct because at this temperature the enzyme produces the higher amount of bubbles.
D. The activity of the enzyme at 0°C was not tested.
Answer:
Azurite and Magnesite react with hydrochloric acid.
Explanation:
These 2 rocks contain the carbonate mineral calcite dolomite. Carbonate minerals are unstable in contact with hydrochloric acid. When acid begins to effervesce (fizz) on a specimen, a reaction takes place and bubbles of carbon dioxide evolve, thus indicating the presence of minerals like calcite dolomite.
Hope my answer is correct and helpful :)

If dominant allele = p, and recessive allele = q,
and p+q = 1, then:

So if 75% have the p, then p^2 = homozygous dominant

And if the other 25% have the q, the q^2 = homozygous recessive

Now those remaining MUST be the heterozygous, thus 2pq are those:
2pq = 2(.75)(.25) = .375
Therefore homozygous dominant are 56.3% and heterozygous are 37.5%
