The answer is B., Natural Selection.
Weather certainly doesn't change populations, and genes only caused individuals in a population to be slightly ( genetically-wise ) different from the others. It does cause change, but not change in the whole population over time.
Natural disasters don't change the populations over time either. Natural disasters only caused change in their environment, at most.
So, the only answer left is natural selection, and it makes sense too!
Natural selection is the process where the individuals with better traits suited to survive in that specific environment live on and give those good traits to their offspring.
The individuals with less suited traits to survive will die out, and will not be given an opportunity to reproduce and pass on their less suited traits, so over time, the population will increase of individuals with better suited traits to survive and the individuals with less suited traits will eventually die out, therefore making the entire population change.
Hope I helped you!
In mitotic cell division, one parent cell produces <u>two identical </u><u>daughter </u><u>cells.</u>
The correct option is (d) Two identical daughter cells.
<h3>Mitotic cell division</h3>
- In mitosis, the cell divides into two identical daughter cell that contains the same number of chromosomes as the parent cell.
- It divides into five stages: prophase, metaphase, anaphase, telophase, and cytokinesis.
- The different stages of this cell division are together called as mitotic phase (M).
Thus, the correct option is (d) two identical daughter cells.

Answer:
B) The completely-plated phenotype is controlled by a dominant allele of a single gene.
Explanation:
<em>The results from the breeding experiment showed that the completely-plated phenotype is controlled by a dominant allele of a single gene because it followed Mendelian pattern of inheritance.</em>
According to Mendel, in a dominant/recessive gene situation, the recessive gene do not manifest physically in F1 generation and at F2, the phenotypic ratio of dominant to recessive gene is usually 3:1.
For example, assuming the completely-plated gene is represented by P and the alternate form (low-plated) by p.
At F1: PP x pp
Progeny: all Pp, completely-plated stickleback in appearance.
At F2: Pp x Pp
Progeny: PP, Pp, Pp, and pp
3/4 of the progeny have completely-plated appearance while 1/4 have low-plated appearance. The ratio of completely-plated to low-plated is 3:1.
The correct option is B.
Only 10% of the energy is transferred from one level to other,
so,
10% of 1,000J = 100 J
Which means 1000-100 = 900J of energy is used upon eating the snake.
(I’m not 100% sure about this answer though, but I think it will give u a good idea about energy transfer)
The message would change because each base has a specific pair that it bonds with. So the original strand's matching sequence would be (ACT GCT) if they were to change the last letter of the first set of 3 numbers, it would be (ACA GCT), and you can see there is a difference in the first sequence of bases. Hope this helps (:
