Answer: predator species would be more sensitive by accumulating toxic material already accumulated in individual prey. It would also depend on different levels of pollution in different niches, so that one species would be more exposed.

Self explanatory
Answer:
In normal conditions, introns serve following functions in the body of an organism:
1) They contain genes of miRNA which are known as Mirtrons, reverse transcriptase, endonucleases, transposase etc.
2) It is because of presence of introns that alternative splicing of mRNA is possible. The sex determination in drosophila is based on alternative splicing.
Apart from this, alternative splicing can be useful and beneficial in an unforeseen situation such as an environmental problem which is faced by the organism for the first time.
Explanation:
Alternative splicing is an important mechanism because with the help of alternative splicing different type of proteins can be synthesized from the same pre mRNA transcript. In case suddenly the surrounding environment of an organism is changed and the environmental conditions have become extremely harsh due to which organism's life is at stake, in such situation organism may make a different type of protein through alternative splicing which can help the organism in survival.
Default splicing in Drosophila leads to the development of male off-spring while female off-spring is produced as a result of alternative splicing.
Answer:
The correct answer is Circulatory system.
Explanation:
Circulatory system is also known as the cardiovascular system which is used to circulate the blood around the body of most of the animals. It mainly consists of a heart that is used to pump the blood and different blood vessel that are used for the transportation of blood to different parts of the body.
The main functions plays by circulatory system are:
1. It provides oxygen to different organs of the body through blood.
2. It helps in providing nutrients, hormones to different organs and remove waste products from cells.
3. It helps in locating the immune cells to the injury site which helps the body to fight the infection.
Introducing a predator means there will be less prey which will help balance the population of prey. Some predators may run out of food and there might be no prey left for them. If the prey were removed the predator population would decline.
Answer:
Plants convert energy from sunlight into sugar in a process called photosynthesis. Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen
