Carbohydrates are covalent linked to proteins (glycoproteins) or lipids (glycolipids) and also and important part of sell membranes , and function as adhesion and address loci for cells. The Fluid Mosaic Model describes membranes as a fluid lipid bilateral with floating proteins and carbohydrates.
how is the electromagnetic spectrum connected to color, light, and temperature?
Answer:
All objects emit electromagnetic radiation, and the amount of radiation emitted at each wavelength determines the temperature of the object. ... Therefore, you can tell the temperature of a star or galaxy by its color because color is closely related to the wavelength at which its light intensity peaks.
Explanation:
How do high temperatures
affect enzyme activity?
Answer:
Increased temperatures can cause enzymes to work more quickly, if the temperature gets too high the enzyme stops working.
Explanation:
If the temperature around an enzyme gets too high, the enzyme loses its shape, which is known as denaturation, and ceases to work.

Answer:
its C B A B
Explanation:
Photosynthesis is a series of metabolic reactions by which plants and algae use sunlight, water (H2O), and carbon dioxide (CO2) to produce molecular oxygen (O2) and energy in the form of carbohydrates (glucose).
Photosynthesis has two types of reactions:
The light-dependent reactions. These reactions convert light energy into chemical energy (ATP and NADPH).The light-independent reactions (dark reactions or Calvin Cycle). These reactions fix carbon from CO2 into molecules which are then used to produce sugar (glucose).The reactants in the light-dependent reaction include light and water (H2O).The products of the light-dependent reactions are ATP, oxygen and NADPH.The reactants in the dark reactions are ATP, NADPH and carbon dioxide (CO2).The product of the dark reactions is sugar (carbohydrates).In conclusion, photosynthesis has two types of reactions: light-dependent reactions and light-independent (Calvin Cycle) reactions.

concentration gradient without using energy.
B. No, it is a form of diffusion.
C. Yes, because it requires energy to move a
molecule against a concentration gradient.
Answer:
A. Yes, because molecules move down the
concentration gradient without using energy.
Explanation:
Active transport is the energy-requiring process of pumping molecules and ions across membranes against a concentration gradient. Both endocytosis and exocytosis are active transport processes.

A unknown element is a gas at room temperature, has 8 valence electrons and 22 neutrons the element is most likely
Answer:
Argon
Explanation:
Argon is a chemical element which is a gas at room temperature, has 8 valence electrons and 22 neutrons. This element belongs to the noble gas elements group.
What is Argon?Noble gas is any of the rare gases that include helium, neon, argon, krypton, xenon, and sometimes radon also and that exhibit great stability and extremely low reaction rates than other elements in the periodic table.
Argon is a chemical element with the symbol Ar and it has an atomic number of 18. It is in the group 18 of the periodic table and it is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.9340 ppmv. It is more than twice as abundant as that of water vapor, 23 times as abundant as carbon dioxide, and more than 500 times as abundant as neon gas. Argon is the most abundant noble gas in the Earth's crust, which comprises about 0.00015% of the crust.

Kaya had an organ transplant. She went to the doctor a week later, and the doctor did a blood test. Her lymphocyte count
had increased. She went to the doctor a month later for the same test, and her lymphocyte count was higher. What is the
best explanation as to why her lymphocyte levels were increasing?
O Kaya was given antibiotics to prevent infections.
Kaya's antigens were attacking the tissue.
Kaya was not tissue typed prior to her surgery, and her body is mounting an immune response.
O Kaya took her immunosuppressant drugs weekly, which increased her lymphocyte count.
Answer:
The best explanation for the increased lymphocyte levels in Kaya is that she was not tissue typed prior to her surgery, and her body is mounting an immune response.
Explanation:
When performing an organ transplant, it must be verified whether the organ to be transplanted is compatible -by tissue typing- with the recipient, since it is recognized as a foreign body by the body and can be rejected.
One of the immunological responses to organ rejection is called cell rejection, involving T-helper and cytotoxic lymphocytes.
It is very likely that in Kaya's case the tests have not been performed correctly, and she is experiencing rejection of the organ she received. The progressive increase in lymphocytes may be an indication of this.
The other options are not possible because:
Administering antibiotics should not raise lymphocyte levels. There is no evidence of antigen attack. Immunosuppressant drugs do not increase lymphocyte count.PLEASE HELP! THIS IS DUE TOMORROW!! I will mark as Brainliest and will reward 15+ points!!!
Question 17 : Describe the features on this map. Where is it steepest? Explain how you can tell that it is the steepest. Which way is the river flowing and how do you know?
Answer:
It is steepest at point B and the river is flowing to the bottom right or southeast of the map.
Explanation:
We can tell that the map is steepest at point B because the lines that display altitude are closest together. Each line indicates 100 miles gained or lost to the overall altitude of the mountain. With the lines closest together, altitude is gained at the most rapid rate, and is therefore the steepest.
Additionally, we can conclude that the river is flowing southeast also because of altitude. The river runs from 1000 altitude to 500 altitude. Since rivers always run downhill, the river will run from the higher northwest point on this map to the much lower southeast point, and is therefore flowing southeast.

Answer:
Osmosis across the membrane
Explanation:
The diagram shows the movement of water molecules from outside the cell to the inside of the cell. The concentration of water molecules is higher outside of the cell than inside the cell, meaning the water molecules are moving from a high concentration to a low concentration across the semi-permeable membrane, a process called osmosis.
Exocytosis is the movement of molecules from the inside of the cell to the outside via a vesicle. The vesicle fuses with the plasma membrane and the contained substances are released outside the cell.
Active transport is the movement of molecules against their concentration gradient and requires energy.
Facilitated diffusion is used by molecules that cannot freely cross the plasma membrane (e.g. large polar molecules and ions)
Answer:
Osmosis across the membrane
