Answer:
Starvation causes a reduction in the <u>oncotic</u> pressure in the <u>cappilaries</u>, thus causing edema in the tissues.
Explanation:
Starvation is the extreme form of malnutrition, in which the caloric energy intake of an individual is much lower than required. The cells of the body start the breakdown of proteins, after the fat stores get exhausted. This reduces the oncotic pressure or the colloidal pressure in the blood vessels or capillaries of the body, thereby causing edema.
Edema is a medical condition, which involves the abnormal accumulation of fluid in the interstitium and cavities of the body.
Answer:
Diffusion expends no energy, however concentration gradients are a form of potential energy, dissipated as the gradient is eliminated. In case you didn't know to dissipate means to disssappear, so diffusion will pretty much just edventually dissappear. It's like when you take a pack of gum out of your bookbag and everyone can magically smell it some time after you've put it away as if they're waiting till you get back to work to ask for a piece, instead it's diffusion. You slowly stop smelling it.
Answer;
G1-phase
The first checkpoint in the cell cycle where a cell will be caused to exit the cycle it this point is not passed is the G1-phase.
Explanation;
The interphase of the cell cycle contains three phases, G1 , S and G2 phases. It begins with G1 phase (G stands for gap). During this phase, the cell makes a variety of proteins that are needed for DNA replication. When the cell passes the G1 checkpoint it enters the S phase of the cell cycle, during which DNA is replicated, after the replication, the cell leaves S phase and enters G2, where the cell prepares for mitosis or meiosis.
The answer is A because coal formations are much younger than the shale.
<span>If we use the </span>law of superposition<span>, we can predict the relative age of each. The coal, closer to Earth's surface, is younger than the deeper shale.</span>
