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.

Lipid-soluble signaling molecules, such as testosterone, cross the membranes of all cells but affect only target cells because
Licemer1 [7]

Answer:

option B) intracellular receptors are present only in target cells.

Explanation:

The cell membrane or plasma membrane is composed of phospholipids and thus hydrophobic in nature, this allows the lipid soluble signaling molecules to cross the membrane. The cell membrane of all cells consist of phospholipids thus hydrophobicity of each cell membrane allows lipid soluble signaling molecules to pass through the plasma membrane. The testosterone cross the membranes of all cells but affect only target cells because of intracellular recepters that are located in target cell. The binding of signaling molecules to recepter generates a response. Thus, option B is correct.

Which of the following observations tells the biologist that the organism is eukaryotic? Choose all that apply. a It has membran
suter [353]

Answer:

a It has membrane-bound organelles

b It converts stored energy to use for cellular processes

Explanation:

Prokaryotic cells lack membrane-bound organelles such as a nucleus and mitochondria, that are present in eukaryotic cells. However, they do have a cell membrane that separates the cell from the outer environment.

Prokaryotic cells do not have mitochondria to break down stored material into energy, instead they obtain their energy from light or chemical sources. This is in contrast to eukaryotic cells, which can break down sugars to produce energy.

Single celled prokaryotes and eukaryotes can both possess flagella
