Answer:
tentatively group it with birds and speculate that the trait shared only with bats is a derived rather than an ancestral trait with bats.
Explanation:
The scientist after his observation should tentatively classify this organism with birds and the the second end of calculating the other morphological traits which makes it possess the likely bat traits to be ancestral.
According to scientists, most widely used modern systematic practice
depends upon the assumption that a change from character in one species
to character occurs once and once only in the evolutionary process and that this process is irreversible so that it never returns.
In this scheme, there are no independently derived parallel evolutionary changes,
nor convergences from a variety of states to a single one. Therefore, when two organisms share a
character state different from other species, it is because they are more closely related to each other through a recent common ancestor than they are to other species.
Also using the parsimony principle, a scheme of common ancestry for all the species is derived that uses all the characters that have been observed.
Answer:
The micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest is explained below in details.
Explanation:
Micrographs are the intensified images collected from small microscopes. Cell micrographs are often obtained from tissue specimens and show a constant mass of cells and inside compositions that are difficult to distinguish individually. It provides accurate images of the exteriors of cells and whole plants that are not imaginable by TEM. It can also be practiced for particle counting and size resolution, and method control.
Answer:
The squirrels over many generations will change shades and colors to match more similarity to the new color of the trees. The colors of the trees could have changed from the weather or maybe there is a hybrid of the trees.
Explanation:
I am guessing but I hope this helps.
Species X and species Z belong to the domain.
Answer: Option A.
<u>Explanation:</u>
Species which belong to the same domain, they also belong to the same kingdom and also to the same phylum. These species are very similar to each other and can also produce offspring together.
In the information given, species X and species Y belong to the same domain. The next column says that the species Y and species Z also belong to the same domain. So species X and species Z will also belong to the same domain.
So let’s substitute that into the
third equation and solve for B. B = H + T B = 9 + (9 + 1/2B) B = 18 + 1/2B Then
subtract 1/2B from both sides: 1/2B = 18 Multiply both sides by two: B = 36 Now
we know the value of B and the value of H. Substitute this back into the second
equation and solve for T. T = H + 1/2B T = 9 + (1/2)36 T = 9 + 18 = 27 Step 4:
Plug all values of H, T, and B into the final equation. Total length of fish =
H + T + B Total length of fish = 9 +27 + 36 = 72.
