Explanation:
What molecules in the cell membrane help move molecules from a low to a high concentration gradient?
Answer:
In simple diffusion, small noncharged molecules or lipid soluble molecules pass between the phospholipids to enter or leave the cell, moving from areas of high concentration to areas of low concentration (they move down their concentration gradient).

Optimal activation of transcription of the GAL genes in yeast requires the function of two proteins: Gal4p and Gal11p. Elimination of either protein decreases activation of the GAL promoters. However, inactivation of Gal11p has the additional and dramatic effect of cell lethality. Why might elimination of Gal11p have a greater effect than elimination of Gal4p
Answer:
Gal4p is a transcription factor that targets specific GAL genes, while Gal11p is a core component of the Mediator complex that plays regulatory roles in the expression of many different genes (class II genes) in eukaryotic organisms
Explanation:
The Gal4 transcription factor is one of the most widely studied eukaryotic transcriptional activators capable of activating the expression of galactose-induced genes. Gal4 is well-known to target specific enzymes involved in galactose metabolism: GAL1, GAL7, and GAL10. On the other hand, Gal11p is a key subunit of the evolutionary conserved Mediator complex that binds to the RNA polymerase II (RNAP II) in order to regulate the transcription of class II genes (i.e., genes transcribed by RNAP II).

1. Human beings continue to grow till the age of.
Answer:
The fastest rate of growth is usually 1 to 2 years after puberty has started. Developing physically into an adult takes 2 to 5 years. Most boys will stop growing taller by age 16 and will usually have developed fully by 18.

Explanation:
Why can’t food chains go on forever?
Answer:
Because at some point in that food chain, the energy consumption has it's limit, and the predator will not have anything to hunt it. There is a limited amount of energy in a food chain that can go around, and once you reach the predator, that energy doesn't quite run out but it hits that limit where the chain has to repeat itself.

Sons and daughters in terms of providing education in our country | What Strategies do you suggest to overcome such discrimination against girls ?
Answer:
well for me i don't think so cause you see now a days that parents treat their children equally they don't have to spoil the son and forgets nout the daughter, parents are equally to their kids and in that case their will be no discrimination at all
Imagine that a plant cell has a damaged large central vacuole that is not functioning.
Which statement BEST describes how this damage will affect the cell’s ability to function in photosynthesis?
A
The cell will no longer allow water molecules into the cell and the mitochondria will lack raw materials.
B
The cell will no longer be able to perform photosynthesis and the mitochondria will lack raw materials.
C
The cell will no longer be able to maintain turgor pressure and the chloroplast will lack raw materials.
D
The cell will no longer be able to store water molecules, maintain turgor pressure, and the chloroplast will lack raw materials.

In the lumen of the proximal tubule, Na concentration is ________ the Na concentration inside the cells of the tubule wall.
Answer:
The correct answer is - higher than
Explanation:
In the lumen of the proximal tubule of the kidney, most of the solutes are absorbed in the form of sodium. There is a gradient of sodium ions which allows the absorption of the solutes from the lumen into the cell.
It is due to the solute or Na concentration is higher in the lumen than Na concentration inside the cells of the tubule wall. So movement of the solutes is due to the concentration gradient.
Analyze Can relative humidity be more
than 100 percent? Explain your answer.
Answer:
Surprisingly, yes, the condition is known as supersaturation. At any given temperature and air pressure, a specific maximum amount of water vapor in the air will produce a relative humidity (RH) of 100 percent. Supersaturated air literally contains more water vapor than is needed to cause saturation.

True breeding plant round seeds (DD) were bred with true breeding smooth
seeds(dd) to produce F1 offspring. F1 offspring were then bred with other F1
offspring. What is the genotypic ratio of the resulting F2 offspring? What is the
phenotypic ratio of the resulting F2 offspring?
Answer:
Genotypic ratio F2 = 1:2:1
Phenotypic ratio F2 = 3:1
Explanation:
In this case, parental genotypes can produce only one type of gamete, i.e., one parent can produce only D gametes, while the other parent can produce only d gametes. Therefore, all F1 generation will be heterozygous (Aa). An F1 hybrid is the first filial generation of offspring obtained from crossing between different parent types. The F1 will produce two gametes (A; a) in a ratio 1:1, thereby the F2 obtained by crossing F1 offspring will have a phenotypic ratio of 3:1 (3 D_; 1 dd) and a genotypic ratio of 1:2:1 (1 AA; 2 Aa; 1 aa).
