During a rainy spring, where are you most likely to find surface runoff? PLEASE HELP
natima [27]

Answer: C. On a sloped parking lot

Surface runoff can be referred as the flow of water, that occurs when the excess water flows from the storm water, melt water, flood, rain streams and rain fall. The fast moving water current takes along with it superficial layers like surface and sub- surface layers of soil. Hence, causes water erosion of soil.

The slope parking lot will favor, surface runoff more likely than in a grassy prairie, mulched flower bed, or in a sand pit because the slope will provide a surface for free flow of water. There are chances that water gets absorbed by the soil in the grassy prairie, mulched flower bed and sand pit. Whereas the slopy surface of parking lot will not allow the water retention by soil, instead will accelerate the flow of water.

_________ cells must be in osmotic equilibrium with their surrounding environments, because if they swell or shrink their membra
dlinn [17]
Well I'm not exactly certain where the teacher is going with this, but an often used example is red blood cells (RBCs) aka: erythrocytes.
RBCs are suspended in blood plasma as they flood through vessels around and around the body, so the osmolarity (amount of small particles that affect osmosis) must remain relatively constant. This is termed "isotonic", meaning the same amount of osmosis-influencing particles that are there inside the RBCs' cytosol, within their plasma membranes.
If the plasma osmolarity get too high, called hypertonic (as with extra salt particles) then water inside the RBCs will have an osmotic force driving it out of the cells' membranes, to flow where there are more salt particles. This will lead to cell shrinkage (called "crenation").
Counter to that, if the plasma osmolarity gets too low, as due to low plasma salt with excessive water intake (for example from the condition "water intoxication"), then the plasma will be hypotonic with respect to the intracellular cytosol concentration. This can result in water rushing into the RBCs' membranes via osmosis, causing the cells to swell from discs into spheres (balls), or even rupture and burst (a phenomenon called "hemolysis").

HOPE THOSE EXAMPLES HELP!!

#1. Which of the following structures would you expect to find in a single-celled organism? A. internal organs B. legs and feet
qwelly [4]
1. outer covering - none of the other answers can occur due to the absorbed solutions inability to reach the centre of the organism, smaller cells in greater numbers are more efficient as they can group together yet all absorb the right amounts of nutrients for its need. multi cellular organisms, such as humans can have the other answers in them as cells group together to make skin, muscles and organs. it also gives the organism to grow larger.

2. bacteria are single celled. bacteria reproduce through mitosis (cell division). bacteria break down decaying matter to obtain energy. every organism requires energy to live. Bacteria can move in order to reach their nutrient source.
