Hypotonic solution means a solution with a higher water potential than the cell
isotonic is the solution with the same amount of water potential with the cell
in animal cell, it only has a semi permeable membrane, therefore when put in hypotonic solution, water molecules will move from the solution to inside the cell by osmosis. the cell may gain so much water that it may burst
in isotonic solution, the net movement of water molecules will be same in each direction , as the water potential is same. that way the cell will not gain or loss water and remain it oiriginals shape
however in plant cells, it has a cell wall. it prevents the cell from bursting. so when put in hypotonic, the cell gain water,but not burst, the cell membrane just push against the cell wall and the cell become turgid
in isotonic solution, same animal cell , no change
Answer:
<u>C. The coastlines of South America and Africa were similar in shape, suggesting that they shared a common tectonic plate.</u>
Explanation:
- As suggested by the Alfred Wegener, the plates of the South America and the African plants had a similar geologic history and thus shared a common tectonic boundary and hence validate the proof of the superclass and the drifting of the plates at various time zones.
- Thus after the 1960s the plate tectonic theory came into the limelight and was heavily recognized to be fit the works of the drifting of the continental landmasses.
Answer:
<h3>Enzymes are typically which type of biomolecule?</h3>
Enzymes are protein biomolecules.
Enzymes are bound to specific substrate/s and act as <u>catalysts</u> that makes chemical reactions faster, such as breaking down lactose to smaller units of glucose, which is accomplished by lactase.
<u>Cofactors (metal ions such as iron, zinc) and coenzymes (organic molecules like vitamins)</u> may be needed to initiate chemical reactions.
<h3>Describe the effects that enzymes can have on substrates.</h3>
After creating the <u>enzyme-substrate complex</u> through <u>induced fit</u>, enzymatic products are seen after the reaction. The <u>substrates may be consumed during the process or preserved</u> to be used again.
For example, these enzymatic products may be used for feedback inhibition to control the chemical reaction and production of a certain hormone.
I thin the the emergency staff member that should provide the care for the client is the Emergency Medical technicians.
These are the appropriate staff who would monitor and track vital signs, perform basic wound care, and also ensure spinal immobilization, as these are basic life support interventions. The paramedics are qualified to perform advanced life support measures. The prehospital care providers on the other hand are the first care providers who help in transportation to the emergency department. Lastly the Emergency medicine physicians recicieve specialized expertise and training in emergency client management.
When the word Storms is used in relation to climatic
controls, we are not talking about tornadoes, hurricanes and the
like. Rather this control deals with the presence of moisture in
the atmosphere, the various means by which moisture is removed
from the atmosphere and the forms the moisture takes.
Meteorologists are very interested in the amount of moisture in
the air not only because the presence of water vapor is an
indicator of the potential for precipitation, but the energy
released as water vapor changes states provides the energy for
storms.
Moisture, or humidity, is a general term we will use to
describe the amount of water vapor in the air. There are a number
of ways to express the amount of humidity in the air -- the most
common being absolute humidity, relative humidity and mixing
ratio. We will take up each of these shortly.
