Answer:

Option B and C

Explanation:

Here in this case Rajesh is concerned about measuring the impact of fertilizers on the growth of plant.  

Thus, a fertilizer is an independent variable and plants are the subject of the experiment.  

In order to improve data validity, Rajesh can conduct the same experiment under the similar conditions for few more times. This will certainly boost his confidence in the result obtained.  

He can also do a comparative study to analyze the experiment result. For doing so he is required to measure the growth of plants that didn't received fertilizer and compare it with the growth of plant that received fertilizers

Hence, option B and C are correct

How can an ecosystem support a variety of organisms in a rainforest
Andrews [41]
I'm not sure what kind of answer you're looking for, but due to the great amount of sunlight, there's lots of energy in rainforests. That energy is stored in plant vegetation, which gets eaten by animals. The canopy of the rainforest also provides many places for animals to live and plants to grow. It also provides interactions between species. For example, t<span>here are some plants in the canopy called bromeliads. Frogs and some other animals use these for hunting & laying their eggs.</span>

Native species are species that evolved in a particular environment and therefore they are well adapted to it.

Native plants are well know to be more adapted to survival and do not need extra watering to survive.

Peyer patches are lymphoid nodules located in the walls of the small intestine.

Peyer patches are also known as aggregated lymphoid nodules, they are organized in the form of follicles and are round or oval and their surface is free of the villi and depressions that are present throughout the intestinal wall.

Peyer patches mainly consist of B cells and play an important part in the immune system by monitoring intestinal bacterial populations and controlling the development of pathogenic bacteria in the intestines.

How could genetic drift explain differences in the genotype frequencies among the caucasian and aborigine populations?
Novay_Z [31]

Genetic drift occurs when there is no random mating across a population. This causes a change in allelic frequency due to a random sampling of the population.

As the aboriginal population explored the earth,  a small part of the population became geographically isolated either due to continental drift and climate changes. As the isolated population grew bigger, they established their own gene pool. This resulted a change in genotypic frequencies from that of the aboriginal population.
