give examples of situation when a substance cannot be moved into a cell by osmosis or diffusion and how active transport solves the problem
When a substance cannot move by osmosis or diffusion, it is because it cannot cross the plasma membrane due to its charge or size, and if it is by diffusion, it is because it is against its concentration gradient.
Why can't a substance go through osmosis or diffusion?A substance could not pass through osmosis since only water can pass to the place with the highest concentration. While by diffusion it could not happen due to its size or electric charge, neither if the concentration gradient is against it.
Active transport helps in this by passing elements against their concentration gradient, generating an energy expenditure for this to occur since this movement is not energetically possible.
Therefore, we can confirm that when a substance cannot move by osmosis or diffusion, it is because it cannot cross the plasma membrane due to its charge or size, and if it is by diffusion, it is because it is against its concentration gradient.

why is fructose toxic to liver cells, but not muscle cells, in individuals with a defect in the enzyme aldolase b?
Fructose is toxic to liver cells, but not muscle cells, in individuals with a defect in the enzyme aldolase, because muscle cells employ hexokinase to convert glucose to glucose-6P, which cannot be further metabolized, liver cells cannot.
In the second stage of the metabolism of fructose, aldolase B is in charge of converting the compound fructose-1-phosphate into glyceraldehyde and dihydroxyacetone phosphate. Aldolase B is also involved in the breakdown of the simple sugar glucose, but to a lesser extent. The lack of the enzyme aldolase B is a defining feature of the autosomal recessive condition known as inherited fructose intolerance.
Fructose-1-phosphate is broken down into glyceraldehyde and dihydroxyacetone phosphate by the crucial enzyme aldolase B. Phosphate depletion and fructose 1-phosphate buildup in the liver are symptoms of aldolase B deficiency. As a result, gluconeogenesis and glycogenolysis are suppressed, which inhibits the synthesis of proteins and causes liver failure.

If your power could have been harnessed and the energy converted to electricity, how many 100-w bulbs could you have kept burning during your climb?
When the power is harnessed and the energy converted to electricity, the person could have climbed using only one 100-W light bulb.
What is power?Power is defined in physics as the amount of energy transferred or converted per unit time. The watt is the unit of power in the International System of Units, equal to one joule per second.
It can be defined as the rate at which work is completed in a given amount of time. Watt (W) is the SI unit of power, which is joules per second (J/s).
And, because our estimate is very rough, we can say that the person's power output is comparable to the power output of a 100 W light bulb. Let's say that the mass is 80kgbabs it takes 30 seconds to climb 5 meters of stair, the energy will be:
= mgh
= 80 × 9.81 × 5
= 3924J
Power will be:
= 3924 / 30

why are fermentation reactions important for cells? they regenerate nad so that glycolysis can continue to operate. they produce alcohol, which enhances the permeability of their mitochondrial membranes to proton translocation. they allow the cell to conserve oxygen for the citric acid cycle. they generate oxygen.
Cells need fermentation reactions because they replenish NAD+ so that glycolysis can continue to function.
Cells require fermentation events in order to continue producing energy even when there is no oxygen present. Glycolysis, or the breakdown of glucose, is converted into pyruvic acid during cellular respiration when oxygen is present. Since oxygen is not needed for fermentation, it is anaerobic. NAD+ will be replenished by fermentation using the NADH + H+ generated during glycolysis. Cells can continue producing ATP through glycolysis after fermentation. A result of fermentation is lactic acid. In fermenting cells, lactic acid will accumulate and eventually restrict the quantity of fermentation that may take place.

There are 2 x 10^18 types of gametes that can be produced from meiosis in a diploid individual just with independent assortment.
Meiosis is a type of cell division that halves the number of chromosomes in the mother cell and produces four gamete cells. The nuclei of cells in the G2 phase have twice the DNA content compared to cells in the G1 phase. Mitosis creates two identical daughter cells, each containing the same number of chromosomes as the parent cell.
In contrast, meiosis produces four unique daughter cells each with half the chromosomes of the parent cell. A specific formula 2n is used to calculate the total number of gametes produced by a particular genotype. where n is equal to the number of heterologous alleles found for the genotype.

Considering their distance apart, the time it will take the tiger to catch its prey is 36 seconds.
What time will it take the tiger to catch its prey?The time will it take the tiger to catch its prey can be determined below as follows:
The two times are equal, hence, let the time it will take the tiger t.
the distance traveled by the cow = d
distance traveled by the tiger = d + 0.25 miles
Time = distance / speedTime taken by the cow = d / 25
Time taken by the tiger = d + 0.25 / 50
equating the two times:
d / 25 = d + 0.25 / 50
25d + 6.25 = 50d
25d = 6.25
d = 0.25 miles
Distance traveled by tiger = 0.25 + 0.25

No disjunction is the name for the meiotic phenomenon of uneven separation. When a haploid gamete with a missing chromosome experiences no disjunction, the haploid gamete will produce a diploid zygote with only one copy of the missing chromosome from the other parent, a condition known as monosomy.
What about chromosomes?Chromosomes are organelles that are present in the nucleus of cells and carry lengthy lengths of DNA.The substance that houses genes is called DNA. It serves as the foundation for the human body. Additionally, proteins found in chromosomes aid in the appropriate structure of DNA. The term "autosomes" refers to the first 22 pairs of chromosomes. A person's gender at birth is determined by the sex chromosomes, which make up the 23rd pair of chromosomes.The highest level of DNA and protein organization is seen in chromosomes. Chromosomes primary job is to carry DNA and pass genetic material from one generation to the next. Cell division involves the critical function of chromosomes. They guard against tangles and damage to the DNA. Another type of aneuploidy is monosomy, which is the loss of one chromosome in cells.
