In some plants, the pistils don't form until a few days after the stamens do. How would this keep a plant from self-pollinating?

Pollination is the process in which pollens are transferred to the female reproductive organs of the plant, where fertilization will take place and give birth to more new plants.

Some plants have the ability to make the stamens mature first before the pistils to prevent itself from self-pollinating. This is because factors found within the environment such as animals, wind, among other, may pre-maturely disperse the pollen into the stigma of the plant. If a situation as such would happen, there will be no pollen left in that flower to land on the stigma to start the fertilization of the plant.

Why do scientists study fossils?

Tasya [4]

Hi,

By studying fossils, scientists can learn how life has changed over time, how earth's surface has changed and what past environments were like. Fossils form when living things die and are buried by sediment; they are usually found in Sedimentary rock. Only the hard parts of organisms generally leave fossils because the soft parts generally decay too quickly to fossilize. In case you didn't know, there are two types of fossils; rock fossils and preserved fossils.

Option c) is the correct option above.

<span>c) Fossils give information about the time period in which organisms lived in the past.

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.
