Based on the question above, the best answer would be:
Interphase
Prophase - condensed
of chromosomes
Metaphase – the cells are lined up at the spindle for its
preparation to be divided
Anaphase – in this part, the chromatids are separated from
each other, and pulled to the opposite ends
Telophase – This is where the cells are nearly done
diving for the cell contents to take
place.
Cytokinesis – Two new cells are formed
Answer:
B. Case-Control
Explanation:
A case-control is a study that compares a group with an outcome of interest (cases) with a group who do not have the outcome (controls). This study aims to looks back retrospectively to compare how frequently the exposure to a risk factor is present in each group and with that to determine the relationship between that risk factor and the outcome.
So in this case, the cases are children with pervasive development disorder and the control is those without the disorders.
These studies are normally observational because no intervention is attempted.
Answer:
D.
Explanation:
Secondary succession occurs in an area that has already been inhabited. If a new island forms from the volcanic eruption, new species may move in and start a new ecosystem there.
Antagonsitic effect/interaction/response
In order to combat antiobiotic resistance, and to possibly enhance the activity of antibiotics, they are sometimes used in combinations during treatment. However, three possible responses or effects can manifest.
First is antibiotic synergy, where the combined effect of the antibiotics enhances the activity/potency of the treatment compared to when the antibiotics are administered singly.
The effect is also distinguished from another type of response, which is additive effect, where the combined effect of the antibiotics is more or less equal to the combined activity/potency of each of the antibiotic when applied singly. Antibiotic synergy results in even greater enhancement of the activity of the combined antibiotics compared to additive effect.
Lastly, there is the antagonistic effect or response, where the combined effect of the antibiotics results in the weakening of the potencies of the antibiotics relative to the combined (additive effect) potencies of each of the antibiotics.
