Natural selection was acting on the population of radish plants. Which of the following DOES NOT satisfy a condition of natural selection as it relates to our radish populations?

a. there was a purple phenotype and a white phenotype
b. the R allele produced a white plant, and rr produced purple plants
c. competition was affecting the reproductive success of at least one of the morphs
d. our populations of radishes were small
e. all of the above are examples of conditions necessary and sufficient for evolution by natural selection

Answers

Answer:

d. our populations of radishes were small

Explanation:

Natural selection is a type of evolution that allows only individuals with favorable characteristics and better adapted to the environment to survive and reproduce offspring with the same favorable characteristics. In this case, to observe a population where natural selection is taking place, population sizes can be disregarded, as this is not a condition for natural selection to take place. However, the other conditions presented in the response options are necessary for natural selection, since it is necessary that there are different phenotypes and genotypes in the population and that competition between them promotes the survival of one group at the expense of the other.

What did Ari draw?

a food chain
a trophic chain
a food web
an energy web

Answers

Answer: Ari draw a food web.

Explanation:

A single ecosystem which contains all the food chains is called a food web.

In a food web each living thing present in a food web is a part of multiple food chains. Hence, food webs tend to represent the overlapping of food chains in that ecosystem.

The flow chart drawn by Ari represents that the living things present in cycle 1 are part of cycle 2 and cycle 3. Also, living things present in cycle 2 are part of cycle 1 and cycle 3.

A food chain is basically a single path where each organism is dependent of the other as a source of food without any overlapping.

Thus, we can conclude that Ari draw a food web.

write paragraph about digestion of food in brief

Answers

Answer:

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Explanation:

according to wikipedia!

Digestion is nothing but breaking down of substances into simpler forms, which the body can use. We eat many things and they have very complex compounds, our body cannot use these compounds. So, different parts of our digestive system breaks down different compounds to simpler forms, so that our body can use it for different functions.

D. Colonial animals.
E. Carnivores that use nematocysts to capture prey.

Answers

Answer:

C. Distinguished by eight bands of cilia.

Explanation:

Ctenophora, also known as comb jellies, represents a phylum of transparent, mostly pelagic, invertebrate marine animals that live around the world. This group characterized by eight rows of cilia (singular cilium) that are used for locomotion. Cilia are organelles and/or structures that extend from the surface of eukaryotic cells, which can be used to move the surrounding fluid, resulting in cell movement. This phylum is divided into two classes: Tentaculata (with tentacles) and Nuda (without tentacles).
