Answer:
B. Lack of sunlight
-------------------------------------------------
Explanation:
A plant can't grow without sunlight because a plant uses the sun to create food using photosynthesis. Too much water won't hurt the plant. Lithium is absorbed by the plant which is a kind of food it isn't very important if it does contain it. Monosaccharides is a kind of sugar that plants can take as food as well but it isn't as important as the food they receive from photosynthesis.

Hope This Helped! Good Luck!
Answer:
This is a model of a mitochondria. .
<u>Mitochondria</u> -: It is the powe house of the cell it contain oxidative enzymes that needed by the stepwise oxidation of food by CO2 and water . The energy released in this process convert to ATP and later it send to the other parts of the body for doing energy requiring activities.
Hope it helps
Complete question: Which Best describes how water moves during osmosis?
A. From passive transport regions to active transport regions
B. From active transport regions to passive transport regions
C. From high solute concentration to low solute concentration
D. From low solute concentration to high solute concentration
Answer:
The correct option is D(From low solute concentration to high solute concentration)
Explanation:
Osmosis can be defined as the thermal movement of water molecules through a selectively permeable or semi-permeable membrane.
A selectively (differentially) permeable membrane will only allow certain molecules to pass through it. Water molecules can pass through a selectively permeable membrane easily but solutes(for example, sugar molecules) cannot.
Using sugar solution to explain further, the following occurs when equal volume of a weak( low solute concentration) and a strong sugar solution( high solute concentration) are separated by a selectively permeable membrane. A diffusion gradient exists between the water molecules in the two solutions. As a result, water molecules move from the low solute concentration to high solute concentration through the membrane. This water movement continues untill there is equal concentration of sugar on the both sides of the membrane.
Answer:
(a) (Glu)zo or(Phe-Met)3 at pH 7.0
O (Glu)zo ✔
O (Phe-Met)s ❌
(b) (Gly) zo or (Lys-Ala)3 at pH 7.0:
O (Gly12) ❌
O (Lys-Ala)✔
(c) (Ala-Asp-Gly)s or (Asn-Ser-His)s at pH 3.0:
O (Asn-Ser-His)s ✔
O (Ala-Asp-Gly)s ❌
(d) (Ala-Ser-Gly)s or (Asn-Ser-His)s at pH 6.0:
O(Ala-Ser-Gly)s ❌
O (Asn-Ser-Hish)s ✔
Explanation:
Polypeptides that has polar or charged side chains are more soluble than polypeptides with nonpolar side chains.
(a) At ph 7.0
(Glu)20 is negatively charged at pH 7 and more soluble
(Phe-Met)3 is observed to be less polar and less soluble
(b)At ph 7.0
(Lys-Ala)3 is positively charged (polar) and more soluble
(Gly)20 is uncharged as only the amino- and carboxyl-terminal groups are charged as its less polar and less soluble too.
(c) At pH 6.0
(Asn-Ser-His)5 has polar Asn side chains and partially protonated His side chains and it's more soluble unlike the (Ala-Asp-Gly)s at that pH.
(d) At pH 3.0
(Asn-Ser-His)s as partially protonated carboxylate groups of Asp residues and it is also neutral but the imidazole groups of His residues are fully protonated and positively charged. Hence it's more soluble than the (Ala-Ser-Gly)s at that particular pH.
