Pls i’m getting timed :(

Answer:

RpPp x RpPp

Explanation:

For the recessive trait to be expressed, both parents should have at least 1 allele for the recessive trait. Now you can see that both recessive traits were expressed in at least one of the off-springs, this means that both parents had the allele for each recessive trait.

Answer:

Water moved out of the cells of the houseplant into the extracellular solution because they (plant cells) have a high water potential (Ψ) than the extracellular environment.

Please find the explanation below

Explanation:

In biology, water potential, denoted by Ψ, refers to the ability of water to move freely in a system. Based on this definition, a hypertonic solution (solution with higher solute concentration) will have a low Ψ while a hypotonic solution (solution with low solute concentration) will have a high Ψ.

According to this question, if a houseplant is fertilized too often, it will increase the concentration of solute in the soil (extracellular environment of the plant cells) i.e. the fertilizer will make the extracellular solution HYPERTONIC. Because the cells of the houseplant are hypotonic to the soil solution i.e. now has a high Ψ in comparison with the soil solution, water will move from the cells of the plant to the soil solution (extracellular) via the cell membrane (semi-permeable membrane) in a process called OSMOSIS.

NOTE: Water moves from a solution with high Ψ to a solution with low Ψ. This is what propels the movement of water from the cell with a high water potential to the exterior of the cell with a low water potential (caused by frequent addition of fertilizer). Overall, the houseplant will look WILTED even if the soil is wet.

Answer:

option c would be the right answer just analyzed the graph

It is true that in the DNAisolation process, cells are mixed with sodium chloride (i.e. NaCl) because the sodium (Na ) neutralizes the negative charge of DNA.

What is DNA isolation?

DNA extraction is a method of separating DNA from cell membranes, proteins, and other cellularcomponents using physical and/or chemical methods from a sample. In 1869, Friedrich Miescher isolated DNA for the first time.

The ability to extract DNA is critical for studying the genetic causes of disease and developing diagnostics and drugs.

It is also required for forensicscience, genome sequencing, detecting bacteria and viruses in the environment, and determining paternity.

Because sodium (Na+) neutralizes the negative charge of DNA, cells are mixed with sodium chloride (i.e. NaCl) during the DNA isolation process. It makes homogenization easier.

Thus, the given statement is true.

Answer:

this is true it neutralise easily

Answer: True

Explanation:

A trans membrane protein is a type of integral membrane protein that is found on the whole cell membrane.

A trans membrane protein function as the gateway and allows the movement of specific molecules or substance across the membrane.

The larger molecules which cannot travel across membrane is transported with the help of trans membrane proteins.

hence, the given statement is true.
