mendel’s experimental method involved using true breed parental plants for each of the traits he studied in the monohybrid cross. why was this vital to the outcomes of the experiment?

Answers

Answer 1

Given what we know about Mendel and his experiments, we can confirm that the benefit of his using true breed parental plants was that it added accuracy and precision to his experiment.

The experiment mentions the use of true breed parental plants for each trait that was studied. A true breed or true-breeding organism is one that will ensure the inheritance of certain physical traits to its offspring through every generation. This is also commonly referred to as a purebred.

The importance of this detail in Mendel's experiments is that it functions as the control variable for the experiment. This is a variable that is maintained constant so that when a change occurs, we can attribute it to other factors and therefore add accuracy to the experiment. Therefore, by starting with purebred parental plants, Mendel could better identify the cause of inheritance for the traits.

If the first nucleotide after the promoter on the bottom DNA strand is changed from C to T, what would the resulting nucleotide be on the mRNA

Answers

I’m pretty sure it’s G U

When the DNA's C is changed to T, the corresponding nucleotide on the mRNA strand will be A (adenine) to maintain the complementary base pairing.

Nucleotides encode genetic information in DNA. Due to complementary base pairing laws, DNA sequence alterations impact mRNA transcript nucleotides. If the first nucleotide following the promoter on the bottom DNA strand changes from C (cytosine) to T (thymine), the matching mRNA strand nucleotide becomes A.

Because C pairs with G (guanine) in DNA and RNA. T in DNA matches A in RNA owing to complementary pairing. The DNA sequence will influence the mRNA sequence during transcription, which may impact the protein synthesised during translation.

what hormone directly opposes the actions of natriuretic hormones?

Answers

Aldosterone!
Explanation: Aldosterone reabsorbs sodium in which is associated with osmotic recovery of water is in direct opposition of natriuretic hormones since it allows secretion of water.

The hormone that directly opposes the actions of natriuretic hormones is aldosterone.

Aldosterone is a hormone produced by the adrenal glands, specifically the adrenal cortex. It acts on the kidneys to promote the reabsorption of sodium ions and the excretion of potassium ions.

Natriuretic hormones, on the other hand, promote the excretion of sodium ions and the reabsorption of potassium ions in the kidneys, leading to increased urine production and decreased blood volume.

Therefore, aldosterone counteracts the effects of natriuretic hormones by increasing sodium reabsorption and reducing potassium excretion, which helps to retain water and maintain blood pressure.

In summary, while natriuretic hormones promote sodium excretion and water loss, aldosterone works in the opposite direction by promoting sodium reabsorption and water retention.

Recall what you know about hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens
to the cell?

Answers

Hypotonic solutions are lowly concentrated solutions
Hypertonic are highly concentrated solutions
While isotonic have equally concentrated

When a cell is placed in a hypotonic sol water moves out of the cell by osmosis making the cell flaccid

When a cell is submerged in a hypotonic solution, water osmosis causes the cell to become flaccid.

What is osmosis?

A semi-permeable membrane is used in the process of osmosis, which allows solvent molecules to move from a solution of low concentration to a solution of high concentration.

Osmosis is a passive process that doesn't require any energy to complete. In order for the concentrations on either side of the membrane to be equal, molecules must shift from an area of greater concentration to one of lower concentration.

Any solvent, including gases and supercritical liquids, can go through the osmosis process.

When solute concentrations inside and outside of the cell are equal, an isotonic solution has been created.When the concentration of solutes outside the cell is higher than within, the solution is said to be hypertonic. When the concentration of solutes inside the cell is higher than outside, the solution is said to be hypotonic.

Therefore, when a cell is submerged in a hypotonic solution, water osmosis causes the cell to become flaccid.

Under the hypothesis of blending inheritance, the offspring of a black cat and a white cat would be GREY.  This theory is not now accepted.

Blending inheritance is an erroneous theory from the 19th century that proposed that offspring inherit phenotypic traits as 'average values' observed for such traits in their parents.

Mendel's laws of heredity (i.e., the Law of Segregation and the Law of Independent Assortment) showed that blending inheritance is based on erroneous concepts.

Moreover, incomplete dominance is an inheritance pattern different from blending inheritance because incomplete dominance refers to the observation that in certain traits both gene variants or 'alleles' are expressed in heterozygous individuals.

B. The cell must be large enough to fight the pathogens.
C. The cell must be large enough to attach to a substrate.
D. The lower limit should be small enough for the cell to move in the fluid efficiently.

Answers

Answer:

c

Explanation:

The lower limit should be small enough for the cell to move in the fluid efficiently. Therefore, option (D) is correct.

The major consideration in setting the lower limit of cell size is the need for the cell to move in fluid efficiently. As cells become smaller, their surface area-to-volume ratio increases, allowing for more effective exchange of nutrients, gases, and waste products across their membrane.

This is particularly important for cells living in fluid environments where diffusion plays a crucial role in these exchanges. Small cells have an advantage in absorbing and expelling substances due to their larger surface area relative to their volume. Therefore, the efficiency of nutrient uptake and waste removal becomes more effective with smaller cell sizes, making efficient movement in fluid environments a significant factor in determining the lower limit of cell size. Thus, option (D) is correct.
