When the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration gradient.
CONCENTRATION GRADIENT:
Concentration gradient is a term used to refer to a difference in solute concentration on opposite sides of the membrane of an organism. If the concentration on the external part of a cell is higher than that of the internal part of the cell, a concentration gradient is said to have occured. Concentration gradient is the basis of osmotic movement of water into and out of a cell. Therefore, When the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration gradient.Learn more at: https://brainly.com/question/8195294?referrer=searchResults

What determines the climate of a location?
Altitude and latitude
Precipitation
Bodies of water
All of the above
Altitude and latitude, Precipitation, and Bodies of water determine the climate of a location. The correct option is D.
What is climate?Climate is the average weather over a longer length of time in a particular place. A description of a climate includes details such as the typical temperature in each season, the amount of rainfall, and the amount of sunshine.
Additionally, the (probability of) extremes is frequently described. Despite the fact that there are other interrelated factors that affect weather, the four primary one are solar radiation, the quantity of which varies with latitude.
Orbital distance from the sun, and Earth's tilt, as well as temperature, air pressure, and the presence of water. The Sun and human activity are two external influences that interact with these as well as one another.
Therefore, the correct option is D, All of the above.

opening and closing of the heart valves is caused by
Answer:
The pressure differences on either side of the valve.
Explanation:
The heart valves open and close passively because of pressure differences on either side of the valve. When pressure is greater behind the valve, the leaflets are blown open and the blood flows through the valve. However, when pressure is greater in front of the valve, the leaflets snap shut and blood flow is stopped.

Could someone please explain this to me in more simpler words? I am not the best at understanding scientific words
design, conduct, and evaluate an investigation to gather evidence that photosynthesis converts light energy to stored chemical energy by showing how leaves take in carbon dioxide and release oxygen at a measurable rate.
Thank you to whoever can help!! I very much appreciate it.
In simpler words this is telling you to make, preform, and explain an investigation to gather evidence that proves that the process of photosynthesis converts light from the sun by making a model or picture of carbon dioxide going into the leef and oxygen coming out at a rate (speed) that you can mesure.

1. Which cell is more sophisticated: prokaryotic or eukaryotic?
2. Give one characteristics you could use to determine whether a cell is prokaryotic or eukaryotic.
3. Give two characteristics you could use to determine whether a cell is a plant or animal cell.
4. Explain the function of mitochondria.
5. Give the name of the organelle that manages or controls all the cell functions in a eukaryotic cell.
Answer:
1. eukaryotic
2. if it's a single cell organism it's prokaryotic, if it's multicellular it's eukaryotic
3. a plant cell will have chlorophyll and cell walls, animal cells lack cell walls and chlorophyll
4. the mitochondria creates energy for the cell through ATP
5. Nucleus
Answer:
Explanation:
1. Which cell is more sophisticated: prokaryotic or eukaryotic?
Eukaryotic Cells are more sophisticated because of multiple factors. One such factor is the fact that Eukaryotic Cells have a nucleus that houses the DNA while the DNA of Prokaryotic Cells are in the cytoplasm. Eukaryotic Cells also have organelles that carry out a variety of functions (Mitochondria, Ribosomes, Endoplasmic Reticulum) whereas Prokaryotic Cells have only the basic organelles (in most cases only Ribosomes).2. Give one characteristic you could use to determine whether a cell is prokaryotic or eukaryotic.
The presence of a Nucleus. Prokaryotic cells don't have a nucleus, while Eukaryotic Cells do.3. Give two characteristics you could use to determine whether a cell is a plant or animal cell.
The presence of a central vacuole (plant cells have a central vacuole but animal cells do not).The presence of a cell wall (plant cells have a cell wall but animal cells do not).4. Explain the function of mitochondria.
The mitochondria are considered the 'powerhouse' of the cell. This is because it is the site of most of the respiratory process which produces energy for the cell in the form of ATP.5. Give the name of the organelle that manages or controls all the cell functions in a eukaryotic cell.
The Nucleus is considered the 'brain' of the cell because it directs all of the cell's functions.(photos by Expii and BioNinja respectively)
