The correct answer is Eutrophication.
When a body of water become enriched with nutrients and minerals and induces growth of algae and plants is referred to as eutrophication.
The process of eutrophication can result to water body depletion.
When there is increase in nutrient levels there is increase in phytoplankton in the water body.
Discharge of nitrates which contain sewage, fertilizer, and detergents in aquatic system may induce the eutrophication.
Answer:
They carry energy
Explanation:
Because energy is carried by changes in matter
The basics would be that you'd need to find out if they could exchange genetic information. If not, they couldn't be considered part of one species. Set-up 2 artificial environments so both groups would produce pollen at the same time. Fertilise both plants with the other's pollen. Then fertilise the plants with pollen from their own group.
Count the number of offspring each plant produces.
If the plants which were fertilised by the opposite group produce offspring, they are of the same species. You can then take this further if they are of the same species by analysing if there is any difference between the number (and health) of offspring produced by the crossed progeny and by the pure progeny. You'd have to take into account that some of them would want to grow at different times, so a study of the progeny from their first sprout until death (whilst emulating the seasons in your ideal controlled environment). Their success could then be compared to that of the pure-bred individuals.
Make sure to repeat this a few times, or have a number of plants to make sure your results are accurate.
Or if you couldn't do the controlled environment thing, just keep some pollen one year and use it to fertilise the other group.
I'd also put a hypothesis in there somewhere too.
The independent variable would be the number of plants pollinated. The dependant variable would be the number of progeny (offspring) produced.
Answer:
Option (B).
Explanation:
Peyer's patches are the small masses of aggregated small lymphatic tissues and provide immunity to an organism. Peyer patches are discovered by the scientiest Johannan Cornard Peyer.
Peyer's patches are located in the ileum region of small intestine. These patches control the growth of harmful bacteria and regulates the growth of intestine bacteria. T
Thus, the correct answer is option (B).
