Mr. Smith is hyperglycemic with a blood glucose level of 300mg/ml of blood. Explain how homeostasis would regulate his glucose l

evels through a negative feedback system.

Answer:

When the animal has eaten food and the blood glucose level in the body increases. The pancreas cells in the body detects the increase in the blood glucose which leads to increase the insulin hormone.

This decreases the blood glucose level in the level. This is how the negative feedback works in the body if the level of glucose increases.

Negative feedback is the way by which the body maintains homeostasis and maintains equilibrium in the body.

Explain why groups 14 and 15 are better representatives of mixed groups than groups 13 and 16
Brrunno [24]
<h3><u>Answer</u>;</h3>

Groups 14 and 15 each contain metals, nonmetals, and metalloids while Group 13 contains metals and a metalloid, and Group 16 contains metalloids and nonmetals.

<h3><u>Explanation;</u></h3>
  • Groups 13–16 of the periodic table contain one or more metalloids, in addition to metals, nonmetals, or both.
  • Unlike other groups of the periodic table, which contain elements in one class, groups 13–16 referred to as mixed groups contain elements in at least two different classes. In addition to metalloids, they also contain metals, nonmetals, or both.
  • <em><u>Group 14 also known as the carbon group contains carbon which is a non metal, silicon and germanium which are metalloids and tin and lead which are metals.</u></em>
  • <em><u>Group 15 also known as the Nitrogen group contains non metals such as oxygen, metalloid tellurium and a metal polonium.</u></em>

How many possible stereoisomers are there of propylene glycol, an organic compound found in clearasil acne cream, caladryl, colg
vova2212 [387]

Answer:

2

Explanation:

Isomers are molecules with the same molecular formula, but with some difference. If that difference is in the manner the atoms are distributed in the molecule, they are called structural isomers; if the difference is the way the molecule is in space, they're called space isomers (cis/trans); and there are the stereoisomers, which the molecules are images that can be overlapping.

The stereoisomers have the property to deviate the polarized light, and, when a molecule has a chiral carbon, it means that it has stereoisomers. The number of stereoisomers is 2ⁿ, where n is the number of chiral carbons.

Chiral carbon is a carbon that bonds with four different structures. So, below is represented the molecule of propylene glycol, and it has only one chiral carbon (see the blue arrow), so, it has only 2 stereoisomers.

Obtain a box of breakfast cereal and read the list of ingredients. What are four chemicals from the list
FromTheMoon [43]

Options:

monoglycerides

cocamide DEA

folic acid

iron chromium ion

peroxide

lauryl glucoside

disodium phosphate

Answer and Explanation:

The added chemicals are:

  • monoglycerides
  • folic acid
  • iron
  • disodium phophates

Monoglycerides are fats added for flavour. Folic cid and iron are vitamins added for nutritional value. disodium phosphate is a food additive for enhancing flavour.

The remaining ingredients are organic based.

The specific heats of two natural substances are shown in the table. Specific Heat Natural Substance Specific Heat Wet Mud 2.5 J
Novay_Z [31]

The specific heat of a substance is heat released or absorbed by one gram for a change in 1 degree celsius

so higher the specific heat, more the heat required to raise the temperature by same extent or more the heat released on decrease in temperature upto same extent (for two substance)

Here the specific heat of sandy clay is 1.4 J/g °C

So it is less than that of wet mud hence sandy clay is needs to release less energy to decrease its temperature
