List molar concentrations (0.0 M, 0.2 M, etc.) at which water entered the potato strips. Why did water move into the potato stri

kati45 [8]

Answer:

- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.

- The solutions are hypotonic to the solution in the potato cells.

Explanation:

According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.

Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.

Photosynthesis transforms blank into chemical energy by blank sugars. Cellular respiration releases the blank from food by blank

creativ13 [48]

Photosynthesis and Cellular respiration, both cellular processes are important for life, however, we need to understand what happens to confirm this information....

<h3>Photosynthesis</h3>

Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.

Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.

<h3>Cellular respiration</h3>

Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

One objective of the degradation of foodstuffs is to convert the energy contained in chemical bonds into the energy-rich compound adenosine triphosphate (ATP), which captures the chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

With this information, we can say that photosynthesis transforms solar energy into chemical energy through sugars. Cellular respiration releases energy from food through sugars.

1. Why do you think the geocentric model was popular for so long?

zhannawk [14.2K]

Answer:

Because humans couldn’t see outside of earth. Gailieo Galilei used his telescope to prove this was wrong ultimately.

More:

it was debunked till the 16th century. Scientists observations and knowledge had advanced too far for the geocentric model to explain them.
I looked like the sun was moving from earth but it really earth thats moving around the sun. The parallax is effect helped explain this.

How do I write a CER paragraph? I need one for Science.

user100 [1]

Well when writing a CER first you need to state your claim after stating your claim you need to support your claim with evidence from your sources and after that you need to give reasons on how your evidence supports your claim
