Answer:
1800km
Explanation:
This question will be answered using the attached S-wave graph.
The graph is plotted as time (y axis) against distance (x axis).
So, when
y = 6 minutes 40 seconds
x = 1.8 * 10³ km
So, we have:
x = 1.8 * 1000km
x = 1800km

A. totipotent, multipotent, pluripotent
B. pluripotent, totipotent, multipotent
C. totipotent, pluripotent, multipotent
D. pluripotent, multipotent, totipotent
Answers
Answer:
C
Explanation:
Totipotent can differentiate into any cell type-Pluripotent into less, and Multipotent being the most specialized.
The types of stems cells in the correct order, from widest range of differentiation to least able to differentiate will be C. totipotent, pluripotent, multipotent.
Totipotent simply means a single, immature cell that can give rise to a new organism. Pluripotent simply means substances that can be able to develop into different stem cells.
Lastly, the multipotent stem cells are the stem cells that can self-renew as they divide and then develop into multiple specialized cell types.
Therefore, the correct option is totipotent, pluripotent, and multipotent.

Explanation:
The GPCRs known in full as G protein-coupled receptors are viewed by many as the largest group of membrane proteins that are found in human genome. They share a common architecture. The seven-transmembrane (7TM) receptors are mostly used interchangeably with the GPCRs even though there are known receptors that have seven membrane domains and do not just signal through the G proteins.

1. Why is it possible for the surface of a pond to freeze even though the water underneath is fluid?
2. Sugar dissolves in water, but is not an ionic compound. What does this tell you about sugar?
3. Water is used in the cells to help transport in the chemicals necessary to survive. Since cell membranes need to be able to hold in and hold out water without dissolving, what do you suspect cell membranes are made from? Why do you think this?
4. Remember "The Wicked Witch of the West" from The Wizard of Oz? She melted when doused with water. What do you think her cell membranes were made of, and why?
5. Find out why hot water freezes more quickly than cold water, and explain it here.
6. Explain why heavy water is heaver than regular water.
Answers
Answer:
Kindly check explanation section.
Explanation:
So, let us dive straight into the solution to this particular Question or problem. We are asked to explain the phenomenon in each case.
(1). Expansion occurs at the surface of a pond water when it freezes at 0°C thus creating higher density for the (liquid) water at below the iced surface.
(2). When sugar is put in water it does not ionized but only dissolved as a molecule, therefore, sugar is a weak electrolyte.
(3). Cell membranes are made of phospholipids and proteins because phospholipids as far will not want to mix with water, also movement of molecules is done by the presence of protein.
(4). The witches cell membranes does not have phospholipids which makes it to have little adhesion force and this was the prime factor in the dissolving of the witch by water. The cell membrane contain nonfatty components.
(5). The statement is true, and this is a phenomenon refer to as the Mpemba effect that is to say when one cools down hot water it looses some of it mass(reduces the quantity of water) and this is due to evaporation. Thus, as the quantity of water reduced, freezing becomes faster.
(6). Heavy water is D2O while normal water is H2O. Where D in D20 means Deuterium which is heavier than Hydrogen atoms in heavy water.

Most chemicals necessary for life dissolve in what?
Don't answer if you don't know.
Answers
Answer:Water is considered the “universal solvent” and it is believed that life cannot exist without water because of this. Water is certainly the most abundant solvent in the body; essentially all of the body's chemical reactions occur among compounds dissolved in water.
Explanation:
Answer:
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Indicate which the following statements are true.
a. During glycolysis, glucose molecules are hydrolysed to yield CO2 and H2O
b. The cleavage of fructose 1,6-bisphosphate by phosphofructokinase yields two molecules of glyceraldehyde 3-phosphate.
c. When subjected to anaerobic conditions, glycolysis in mammalian cells continues and causes a buildup of pyruvate in the cytosol.
d. In the mitochondrial matrix, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH.
e. Fatty acids can be transported into mitochondria and converted into acetyl-CoA, FADH2 and NADH
Answers
Answer:
The correct answer is: D
Explanation:
(a) This process does not occur during glycolysis, it occurs after glycolysis since pyruvate is generally accepted to be the last product of glycolysis
(b) Phosphofructokinase does not produce two molecules of glyceraldehyde 3-phosphate but rather produces of one molecule of glyceraldehyde 3-phosphate and dihydroxyacetone phosphate
(c) During anaerobic conditions in mammals, pyruvate is converted to lactate by the enzyme lactate dehydrogenase. It can actually cause the accumulation of lactic acid/lactate in the muscle which causes muscle fatigue but does not cause buildup of pyruvate in the cytosol.
(d) In the fate of pyruvate, the pyruvate dehydrogenase complex produces CO2, acetyl-CoA and NADH in the mitochondrial matrix. The acetyl-coA produced thereof serves as a precursor for the citric acid cycle.
