Explain how the shape of a river's stream bed can affect the river's speed and its power to cause erosion.

Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.

When the centromeres split in mitosis,what does the sister chromatids’ name change to?
snow_lady [41]

Answer:

During anaphase 2, the chromosomes' centromeres break, and the spindle fibers pull the chromatids apart. The two split portions of the cells are officially known as "sister chromosomes" at this point.

Fil in the blanks:1. A fat molecule is composed of two types of smaller molecules, including only one molecule of _________. 2.
Sedbober [7]

Answer:

1. Glycerol

2. Fatty acids

3. Monoglycerides

4. Triglycerides

5. Hydrocarbon

6. Hydrophobic

Explanation:

1. Glycerol

Fat consist of a molecule called glycerol that is attached to one, two, or three fatty acids. Glycerol is the basis of all fats and consists of a three-carbon chain that is attached to the fatty acids.

2. Fatty acids

Fats is made up of three fatty acids and a glycerol, it can also be called triacylglycerols or triglycerides.

3. Monoglyceride

It is a glycerol molecule with a singular fatty acid. It is formed through the combination of OH of glycerol to the OH of the fatty acid.

4. Triglycerides

It has three fatty acid molecules. It is a tri-esters made up of a glycerol attached to three fatty acid molecules.

5. Hydrocarbon

Fatty acids is made up of long, unbranched hydrocarbons with a carboxylic acid group found at one end.

6. Hydrophobic

The hydrophobic nature of fat arises from the carbon-hydrogen bonds that are nonpolar.
