The change in subunits or the direction of the bonds results in the formation of a different carbohydrate and thus a change in structure and function is seen.
The carbohydrates which are also known as the sugars are macromolecules which are required by the body as they are a very essential source of energy for the body. The carbohydrates basically exist as either monosaccharides, disaccharides or the polysaccharides. The disaccharides and the polysaccharides are made up of simpler units which are the monosaccharides.
A small direction change which might occur in the components of a molecule, for example, the placement of -OH in alpha glucose vs. beta glucose basically can result in causing some functional differences. For example, joining of alpha glucose will form starch which is basically used for energy storage in plants and if there is a joining of beat glucose will form cellulose which is needed for structural support in plants.

Which does not cause rapid growth in a population?
A. elimination of a pollutant
B. elimination of predators
C. increase in food supply
D. introduction of a new parasite
E. introduction into a new habitat
Answer:
B. elimination of predators does not cause rapid growth in a population.
Explanation:
B. elimination of predators does not cause rapid growth in a population. In fact, the elimination of predators often leads to a decrease in the population size of the prey species, as without the predation pressure, the prey population may exceed the carrying capacity of the environment, leading to increased competition for limited resources and other factors that can limit population growth.
A, C, D, and E can all cause rapid growth in a population, although the specific effects may depend on the species and the particular circumstances. For example, the elimination of a pollutant can improve the health and survival of individuals in a population, leading to increased reproduction and population growth. Similarly, an increase in food supply can lead to increased reproduction and survival, while the introduction of a new parasite can reduce the population size of the host species, potentially leading to an increase in the survival and reproduction of the remaining individuals. Finally, the introduction of a population into a new habitat can often lead to rapid population growth as the population expands into an area with more resources and fewer limiting factors.

what are the main difference between animal and plant cells??
How do these differences influence the internal structure of these cell
The main difference is that Animal Cells do not have a cell wall, plants do. there's obviously more but I believe that's the main difference
A cell membrane and a cell wall are features of plant cells. The cell membrane is surrounded by the cell wall in plants. The plant cell's distinctive rectangular shape is due to this. Plant cells lack the centrosome and lysosome, while animal cells only have a cell membrane and no cell wall, giving them a circular shape. Unlike animal cells, plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole.

Is allele frequency the same as phenotype frequency?
Allele frequency is not the same as phenotype frequency. This is because allele frequency explains the frequency of occurrence of a particular gene or allele, not a trait.
Allele frequency describes the frequency of a particular gene or allele that shows up in a given population. Whereas phenotype frequency describes the frequency of occurrence of a particular trait in a given population. p and q are used to denote allele frequencies. The phenotype frequency gives the frequency of traits.
For example, let's consider the occurrence of the white and purple colors of a flower. The allele for purple is W and for white is w. The frequency of occurrence of W and w give the allele frequency. And, the frequency of occurrence of white and purple colors gives the phenotype frequency. Therefore, allele frequency and phenotype frequency are not the same.

how cells regulate their sensitivity to circulating hormones
Cell sensitivity might grow or decrease depending on the quantity of hormone receptors present.
Up-regulation, a reaction to growing hormone levels that makes the cell more responsive to the hormone and permits increased cellular activity, can cause the number of receptors to rise. Moreover, the quantity of hormone receptors that activate cells might alter throughout time, increasing or decreasing the sensitivity of the cells.
Up-regulation occurs when the number of receptors rises in response to an increase in hormone levels, increasing the sensitivity of the cell to the hormone and enabling higher levels of cellular activity. Humoral stimuli, hormonal stimuli, and neurological stimuli are the three main ways that endocrine glands are triggered to produce and release hormones.

At what stage does a cell become committed to the cell cycle?
A cell becomes committed to the cell cycle at the G1/S transition.
This transition marks the start of the cell cycle and marks the point at which the cell has decided to divide and is no longer able to return to the G1 phase. At this point the cell begins to replicate its DNA, transcribe its genes and synthesize proteins required for the cell cycle. This is the point at which the cell is committed to the cell cycle and will continue to progress through the cycle until it enters the G2 phase.The cell cycle, also known as the cell-division cycle, is a series of actions that leads to the division of a cell into two daughter cells. These events involve the duplication of its DNA (DNA replication) and a few of its organelles, followed by the process of cell division, which entails splitting the original cell into two daughter cells and dividing its cytoplasm, chromosomes, and other constituents.

Lipoprotein particles that is generated by the action of lipoprotein lipase on VLDL particles. Lipoprotein lipase is an enzyme that is responsible for breaking down triglycerides in lipoprotein particles in the bloodstream.
When LPL acts on very low-density lipoprotein particles, it converts them into intermediate-density lipoprotein (IDL) particles by removing some of the triglycerides.IDL particles are therefore the lipoprotein particle that is generated by the action of lipoprotein lipase on VLDL particles. IDL particles are intermediate in size and density between VLDL and low-density lipoprotein (LDL) particles, and they can either be taken up by the liver or further broken down into LDL particles.
