I believe the part of the cell theory you can use to refute his claim is that cells are the smallest unit of life and more importantly that all cells come from other living cells.
Answer: Correct options B, D and E.
Explanation:
In the cladogram, we can see that in the first branch we have a division, one branch goes to fish and the other goes to a division (a division means a common ancestor)
Then the fish are the most primitive (being directly related to the first ancestor)., E is true.
We also can see that between fish and birds we have 3 separations (the ancestor in common is 3 "generations" behind), and between frog and birds we have two separations (the common ancestor is 2 "generations" behind), so frogs are more closely related to birds than fish.
So D is also true.
We also can see that the only pair that has only one ancestor in common are birds and reptiles, so the ones that are most closely related are birds and reptiles. B is also true,
Answer:
With 6 we should multiply gross photosynthesis (as we were measuring gross photosynthesis for 10 min).
Explanation:
According to this question:-
Net photosynthesis- 3mm/20min- 1.5mm/10min
Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we gage the photosynthesis rate in hr.
A culture medium consisting of agar, human blood, and beef heart is a
B) Complex medium
Answer:
The correct answer would be phenotypic variation.
Phenotype refers to observable traits or characteristics of an individual. For example, height, color, shape, et cetera.
Phenotypic variation refers to the sum total of variations in characteristics within populations of the same species.
In contrast, genotypic variation refers to the sum total of variations (such as allele frequency) present in the genome of populations of the same species.
