Answer:

A. A disease in the population of rabbits.

Explanation:

I would say it is as a result of disease in the population of rabbits.

From the graph we would see that the grass population gradually increased this is as a result of the number of rabbits feeding on it decreased.

The four populations started out at their ideal values, it is likely that these changes were the result of a disease.

Because the rabbit population was the first to decrease, it is most likely that the disease occurred in the rabbit population, once this happen the snake population then decreased because its food supply (the rabbits) decreased. Since the snake population decreased, the hawk feeding on the snake population also decreased.

So the answer is A

A disease in the population of rabbits.

Based on the graph, you can see that the population of grass is high, which indicates that the one that feeds on them has been affected. Logically, the rabbits are those that feed on it and as you can see, their population has lowered, and so did the snakes and the hawk.

So among the choices, B. a disease in the population of rabbits may have lead to the graph shown.

Class Mammalia is divided into two subgroups: marsupials and placental mammals.

White raven [17]

Answer:

The given statement is false.

Explanation:

The mammals can be differentiated into three main groups on the basis of the development of their babies. These three groups are marsupials, monotremes, and placental mammals, which is the largest group. The monotremes refer to the mammals, which lay eggs. The marsupials refer to the mammals, which give birth to young ones that are not developed completely. While in a placental mammal, the development takes place within the body of a mother until and unless its systems of the body start to work on their own.

Please choose the answer that best completes the blanks of this sentence in the correct order. _______ are substances that provo

Inessa05 [86]

The correct answer is antigens and epitope.
An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.

What percentage of the total energy consumed was converted to forms that were unusable to become new growth for the chipmunk?

mrs_skeptik [129]

The percentage of energy that is unusable is obtained as 96.1 %.

<h3>What is the percentage of unusable to become new growth for the chipmunk?</h3>

We know from the law of conservation of energy that energy is neither created nor destroyed in the ecosystem but is converted from one form to another. We know that the ecosystem is a self supporting system in which there is an exchange of materials and energy. Energy flows from the producers to the consumers and some of this energy is dissipated along the way and is lost as heat during the transition.

The metabolic activities of an organism takes up some part of the energy that it receives from the sun.

From the question, we know that the energy consumed is 1000 J and the energy that is lost to waste and to respiration is 177 J and 784 J respectively. This implies that the available energy is 39J.

The percent of energy that is usable is; 39 J/100J * 100/1 = 3.9 %

The percent of energy that is unusable is; 961 J/1000 J × 100 % = 96.1 %
