What strengthens and helps to maintain the fluid nature of a cell regardless of temperature?
Amanda [17]

Cholesterol in Cell membrane  strengthens and helps to maintain the fluid nature of a cell regardless of temperature

<u>Explanation:</u>

All organisms are made up of one or more cells. Each cell is protected or differentiated by a covering called as the cell membrane. Phospholipids are the basic structure of the cell membrane. Cholesterol prevents the loss of fluid from phospholipids.  

Cell membrane has a lipid layer and cholesterol which is placed between the phospholipids to maintain the fluid nature of the cell under different temperature. Cholesterol prevents the cell from solidifying and helps maintain the fluid. Cholesterol actually acts as a buffer between different temperatures.

Biology Photosynthesis questions
Mazyrski [523]

I cannot do the part A task...... I can do the chart (: annddd the questions below..

Glucose: Glucose is a sugar made from sunlight, with the molecular formula C6H12O6.

chloryphll: The energy that is absorbed of the photon is transferred to an electron in a process called charge separation.

ATP: is a product of the first stage of photosynthesis, and it provides energy for the second stage. energy transfer; that is, ATP is able to store and transport chemical energy within cells.

Carbon dioxide: is involved in the production of refrigeration systems, welding systems, water treatment processes

chloroplast: contains the molecule chlorophyll, which absorbs sunlight for photosynthesis.

stomoata: control the flow of gases in and out of leaves.

Thylakoid: A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis.  surrounded by a lunon.

stroma; involved in the Calvin Cycle – carbon fixation, reduction and regeneration. the stroma the supportive tissue of an epithelial organ, tumor, gonad, etc.

----------------------------------

Q2: oxygenic photosynthesis and anoxygenic photosynthesis.

Q3: The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.

Q4: water, light and carbon dioxide, while the products are oxygen and sugars.

Q5: carbon dioxide + electron donor + light energy ==> carbohydrate + oxidized electron donor + water

CO2 + 2H2A + photons ==> [CH2O] + 2A + H2O

Explain why and how theories may be changed or replaced over time.
Tpy6a [65]

Answer and Explanation: This is true that theories do change or get replaced overtime. We all know that in any scientific investigation the scientist put forth the theories which are basically the ideas explaining something particular. We also know that the world is experiencing constant changes and those changes could be of Technology or of overall world order so, whenever a scientist gives us the theory, that theory is made according to the situations and environment of that particular time and in future with the passage of time and with the advancement of Technology and other variables, scientist do need to re-evaluate theories. They either make some positive changes keeping in view the changing circumstances of the current situation or discard the theory altogether depending on its nature. The name research itself indicate that scientists research the already searched idea and in that way the New theory which comes after the modification of old theory or altogether the new theory takes place of the old one.
