Goblet cells are glandular cells, or unicellular mucus-secreting glands, present in the epithelial lining of the mucous membranes of the respiratory tract and digestive system. The mucus produced by a goblet cell is secreted in the light of the tubule in question by exocytosis and diluted with water in order to coat the epithelium exposed to harmful actions present in the digestive or respiratory tubes.

​A carbon atom has 6 protons and 6 electrons. Carbon has three naturally occurring isotopes, carbon-12, carbon-13, and carbon-14
Ede4ka [16]

Answer:

The correct option is B

Explanation:

Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, <u>all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons</u>.

However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.

Hence, the number of neutrons in carbon-12 is 12 - 6 = 6

the number of neutrons in carbon-13 is 13 - 6 = 7

the number of neutrons in carbon-14 is 14 - 6 = 8

From the explanation above, <u>it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different</u>. Hence, the correct option is B

What period(s) show the most rapid increase in adipose tissue?
Sergio [31]

Answer:

a and b

Explanation:

The growth of adipose tissue in newborns is directly linked to the fact that they do not have proper body temperature control, so fat acts as a thermal insulator in order to maintain a constant temperature, also, breast milk density can also influence baby fat gain.

For the first six months the baby still has a lot of fluid retention and so it may give the impression that he is getting fatter, but after the first six months until the end of the first year, the baby tends to lose this fluid, decreasing on average 10% of body weight.

<u>Girls</u> in adolescence and pre-adolescence have a tendency to gain weight due to the enormous hormonal load they receive at puberty, as well as other factors such as poor diet.

The same does not happen as often in <u>boys</u> because a good part tends to have a "leap" growth in puberty, favoring weight loss. The process of fattening in teenage boys is more associated with sedentary practices and consumption of junk food.
