Hydrogen ions play a central role in the lives of cells. For example, changes in hydrogen ion concentration are intimately tied to the charge of side chains in proteins. This charge state, in turn, affects the activity of enzymes as well as their folding and even localization. Further, the famed ATP synthases that churn out the ATPs that power many cellular processes are driven by gradients in hydrogen ions across membranes.

hope this helps!!

Molecules move from greater to lesser concentration through a transport protein in

Facilitated diffusion

<span>The word 'diffusion' means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs. This is possible due to the structure of the cell membrane. The structure is such that, it allows only certain things to pass in and out of the cell. One such activity that allows selective movement in and out of the cell is the process of facilitated diffusion.</span>

When health care teams solve problems, it is important that in the final stage, all team members _____. Have a say in the goals

Nadusha1986 [10]

Answer:

The correct answer is ''understand their roles''

Explanation:

Teamwork in a health team is considered important as a way of dividing responsibilities, correctly attending to the roles in a work team and the functions of the figures that intervene in the teamwork in order to achieve recovery the health of the patient more quickly. Each of the health professionals in this group or team must have a role to fulfill the desired objective; the team is a group of individuals who cooperate to perform a particular routine activity; there is a link of reciprocal dependency that unites the members of the same team with the others. This vision is justified, for each professional to have a different perception of the situation, it is the “union” of the different perceptions that facilitates the understanding of the whole, allowing a glimpse of the patient as a whole. Usually, the general doctor assumes the role of knowing the patient in depth, in order to be able to guide on health problems and decide together with him or her the treatments and objectives to be achieved.

If the number of cigarettes smoked increases, then the risk for lung cancer increases. Independent variable: _______ Dependent v

hodyreva [135]

Complete Question:

Part A: Identifying Variables

Read the following hypotheses and identify the variables.

If the number of cigarettes smoked increases, then the risk for lung cancer increases.

Independent variable: _______

Dependent variable: _______

If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.

Independent variable: _______

Dependent variable: _______

If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.

Independent variable: _______

Dependent variable: _______

Answer/Explanation:

Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.

Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.

In the above given hypotheses, the dependent and independent variables are shown below:

1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".

"Risk for lung cancer" => dependent variable

Number of cigarettes => independent variable

2. "number of shark attacks on humans" is dependent on "number of sharks swimming".

Dependent variable => number of shark attacks on humans

Independent variable => number of sharks swimming

3. Dependent variable => strength of bone

Independent variable => amount of milk a person drinks

Many chemotherapy drugs used to treat cancer work by modifying the mitotic spindle. Paclitaxel works by interfering with normal

Minchanka [31]

Answer:

by inhibiting the mitotic spindle plasticity

Explanation:

In eukaryotic cells, the mitotic spindle is the cytoskeletal structure by which sister chromatids are separated during cell division. Spindle microtubules are known to drive chromosome segregation, while tubulins are Microtubule-Associated Proteins (MAPs) that attach to microtubules in order to modulate their dynamics. Antimitotic drugs are nowadays widely used in chemotherapy to disrupt microtubule assembly and chromosome segregation, thereby producing mitotic arrest and cell death (apoptosis).
