Answer:

B = 20 b

3.5 Kg

Explanation:

Given

Body mass of rhinoceros = 3000 Kg

Blood mass of rhinoceros = 150

It is also given that blood mass is proportional to the body mass of the species.

Thus, if B represents the body mass and b represents the blood mass the relation between the two can be represented as

B ∝ b

On introducing a proportionality constant "k" , the relation becomes

B = kb

The value of proportionality constant "k"  can be determined by substituting the given values of B and b in above relation -

3000 = k * 150\\k = \frac{3000}{150} \\k = 20

Thus the relation becomes

B = 20 b

Part A

estimate the blood mass of a human with body mass 70 kilograms.

Substituting the given values , we get

70 = 20 * b\\b = 3.5

The plasma membrane needs lipids, which make a semi-permeable barrier between the cell and its environment. It also needs proteins, which are involved in cross-membrane transport and cell communication, and carbohydrates, which decorate both the proteins and lipids and help cells recognize each other. Hope this helps :)

True [87]
Fatty acids and glycerol best describes the basic structure of lipids. Fatty acids is one of the major components of triglyceride. It is a form of lipids that is used to store energy. Fatty acids are composed largely of a chain carbon atoms bonded with hydrogen atoms. At one of the ends of fatty acids is called carboxyl group. In terms of number of carbons, they are typically an even numbers.

A population of mussels was observed in a particular ecosystem. Crabs have recently been observed occupying this ecosystem, whic
Zina [86]

Mussels are molluscans and are freshwater animals. The change in the environment led to new traits of mussels, it underwent natural selection and the thick shells have high chances of survival.

<h3>What is natural selection?</h3>

Natural selection is a process of nature that eliminates the organism with less survival and unfit traits while selecting the organisms with better traits of survival in the altered conditions.

The arrival or the introduction of the crabs in the environment altered the previous habitat of the mussels and led to the adaptation of the better trait quality in the mussel species.

The trait of the thick shells underwent natural selection as they were favoured for the changed conditions. The mussel having thick shells have high chances of survival over thin-shelled mussels as the crab will find it hard to attack the thick-shelled mussels.

Therefore, option A. change in environment, option B. natural selection and option E. chances of survival are the correct statements.
