Answer: Option E) polar

Amino acid-derived and peptide hormones are unable to diffuse across a cell membrane because they are polar

Explanation:

Amino acid-derived and peptide hormones such as serotonin, epinephrine, dopamine etc, are unable to diffuse across a cell membrane because they consist of several repeating units of amino acids with positively charged or negatively charged side chains.

Thus, the side chains make these hormones water-loving (hydrophilic), and impassable to the hydrophobic layer of the cell membrane.

Alligators, crocodiles, and snakes are all reptiles. However, alligators are more closely related to snakes. Which statement MOS
Delvig [45]
Are there any statements given for this assignment? Because according to what I know, alligators and crocodiles are more related to birds because of archosaurian origins. However, crocodiles are more closely related to birds than snakes because the evolution of birds  from having snouts to beaks are slightly evident in crocodiles for they have more pointly snouts.

Area measuring 5 m² contains 50 earthworms what is the population density of the earth worms
Darina [25.2K]

The density of a population of living organisms is usually measured in individuals on one square km. In here we have 50 earthworms on an area of 5 square meters, thus we have 10 earthworms on every square meter. In order to get to the result we need to see first how many square meters there are in one square km. One square km has one thousand meters of length and one thousand meters of width so:

1,000 x 1,000 = 1,000,000 km²

Since we established that we have 10 earthworms on every one square meter, we just need to multiply the number of square meters with the amount of earthworms on every square meter:

1,000,000 x 10 = 10,000,000

So we have a density of 10 million earthworms per square km.
