Answer:

In summary, breathing is the process of inhaling and exhaling through our lungs. It brings oxygen into the body and expels unwanted carbon dioxide. ... Our cells perform cellular respiration with oxygen and glucose to make energy and carbon dioxide.

A certain restriction enzyme digest results in DNA fragments of the following sizes: 4,000 bp, 2,500 bp, 2,000 bp, and 400 bp. S
Paladinen [302]

Answer:

Smaller the size of the DNA fragment, farther it moves during electrophoresis. The sketch of the position of the fragments has been drawn in the figure below.

Explanation:

As we know DNA is a negatively charged molecule. So during electrophoresis the fragments move towards the positive electrode because opposite charges attract each other.

Different fragment move different distances according to their size during the electrophoresis. Smallest segment travels the largest distance in the gel medium while the largest one travels least distance.

In the question there are four DNA fragments with base pairs 4000, 2500, 2000 and 400 so the smallest segment with 400bp will be farthest from the starting point and the largest fragment with 4000bp will travel least distance in the gel medium. Their respective positions are shown in the figure below. The starting point is near the negative electrode.

liberstina [14]

The correct answer is option (D) Lipid molecules are nonpolar because they repel water molecules, which are polar.

Lipids are organic compounds made up of fatty acids and glycerol. A glycerol is a organic molecule with three hydroxyl groups and a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group.

Lipids are hydrophobic, nonpolar molecules with no charge on their ends. Waxes are long chain nonpolar lipids. The water repelling property of the waxes prevent the water sticking to it and appear as water beads on its surface. The hydrophobic hydrocarbon tail of the fatty acids are hydrophobic in nature making them repel water. The presence of wax on the surface of the plants and animals protects them from dehydration.

Thus, the nonpolar property of lipids make it insoluble in the polar solvents like water as there is no interaction or sharing of electrons between them.

WINSTONCH [101]

The dependent variable is what changes because of the independent variable, while the independent variable is what is purposefully changed by the experimenter, since it is the variable that is being tested.

So, in this problem, you are purposefully changing the distance of the race to see whether or not the amount of time taken to complete the race will change because of the varying distances.

This means that purposefully changing the distance of the race is the independent variable that is being tested and that the amount of time that the runner takes to complete the race is the dependent variable because it changes due to the independent variable.

Sorry for being so wordy.

In short,

Independent variable- the one that's being tested and that is purposefully changed.

Dependent variable- the one that changes because of the independent variable.

Hope this helps.

What is a branch point on a cladogram
Anestetic [448]
A cladogram is a chart which demonstrates cladistics. A branch point on a cladogram branches off from a common point in a cladogram, which shows that the two organisms share a common ancestor. Hope this helps! (:
