Cell biologists studying the mobility of plasma membrane proteins fused mouse and human cells together, creating a heterokaryon. They then examined the localization of mouse and human proteins over time. Initially the mouse and human proteins were restricted to separate halves of the heterokaryon. Over time the mouse and human proteins mixed, with each protein eventually being present over the entire cell surface, consistent with proteins being able to move within the plane of the membrane. What techniques could have been used to examine the locations of the mouse and human membrane proteins

Answer: Fluorescence microscopy

Explanation:

A protein is substance that is the essential constituent of living cells because it forms part of its structure. They are also found in plasma membrane, where they assist substances to cross the membrane.  Proteins can be:

Some integral proteins can act as cellular receptors. Other proteins are responsible for cell adhesion (binding of a cell to another cell or to a surface). On the outside of the cell membranes, attached to other proteins, are the carbohydrate chains that act as labels identifying the type of cell.

A heterokaryon is a multinucleate cell and in this experiment the scientists fuse a human cell and a mouse cell, each of them will have their own proteins. At first, the human and mouse proteins where found in separated halves of this heterokaryon. But after a while, those proteins where mixed and could no longer be identified.

A fluorescent chemical called a fluorophore is able to be absorb light of specific wavelengths and then emit light of longer wavelengths. The proteins can be modified and marked with different colored fluorophores to detect them, even if they are mixed in the heterokaryon. Then, they can be seen with a Fluorescence microscopy, to identify them through different colors.  

As the fruit develops, why do the petals, stamen, and sepals fall off?
A. The fruit absorbs them, which gives the fruit its color.
B. They have served their purpose and are no longer needed by the plant.
C. The material in the petals, stamen, and sepals become the skin of the fruit.
D. The flower has become dehydrated.

Which statement explains the role of genes in the process of inheriting a specific trait? Question 8 options: Genes are changed by the environment of a living thing and these changes effect the genes of the offspring. Genes in living things come together to make chromosomes which take information from offspring to parent. Genes absorb chemicals from the blood stream and carry them throughout the body of parents and offspring. Genes which are past from both parents carry the genetic material that determines inherited traits.

Which of the following statements is true regarding the vice president's role in the Senate?
In recent years, vice presidents have been less active in the Senate.
Most modern vice presidents have voted hundreds of times in the Senate.

The vice president may cast a vote in the Senate whenever they chose.

Predict the two possible outcomes if temperature or pH were changed within the molecular control system of cell division.

I'm pretty sure it's that the cells would divide more or divide less, right? Because the temp or pH change would cause some enzymes to denature, and then, depending on which ones denature, the regulation of cell division would be messed up and they would either divide too much or not enough?

Please select the word in parentheses that fits the sentence:
A catalyst [weakens/strengthens] the bonds of the reactants [increasing/decreasing] the activation energy.
