Answer:

The correct answer is c. water to move out of the strawberry, making it smaller

Explanation:

Osmosis is the process refers to the movement of liquid molecule from the area of high solute concentration to an area of low solute concentration through a semipermeable membrane to equalize the osmotic balance.

Osmosis is important for any cell to maintain a proper osmotic balance of the cell. So if sugar is sprinkled on a strawberry the solute concentration outside the strawberry cells will increase which will result in water release from the cell.

This release of water from the cell will shrink the strawberry and make it small. Therefore the correct answer is c.

1. The glutamate causes an influx of ca2+ ions into the nerve cell akin to what occurs during depolarization. However, this occurs excessively without regulation (due to excessive stimulation by the glutamate) that eventually causes nerve injury through cytotoxic edema.

2. When the ca2+ levels are lowered during stroke, then nerve cell injury would be obviated hence enabling the chances of restoration of nerve cell function. This would happen because there would be no excess calcium ions to influx when the NMDA receptors are excessively stimulated by the glutamate molecules.

Which term best describes the difference in colors of the birds below?

NeX [460]

Answer:

The correct option is C) genetic variation

Explanation:

Genetic variation can be described as the differences present in the genetic material i.e DNA of organisms present in a population. Genetic diversity allows organisms of a species to better adapt to an environment. A population in which the genetic variability is scarce might become wiped out by a disease or an invading predator.

As the birds show different variations hence the term that best described them is genetic variation.

Brainliest answer for correct. Thanks

makvit [3.9K]

Answer:

The correct answer is option B, Encourage people in the neighborhood to use more disposable products.

Explanation:

The best way to reduce the waste is to stop its negative impact at the source of generation. In a neighbor hood, all the house can be considered as a source of waste generation. Thus if people are encouraged to use disposable product, it would be very easy to just collect and dump the waste without segregation. This will save time, money and effort.

In fruit flies, straight wings are dominant and curly wings are recessive. What will the generations look like? Assume that Mend

anzhelika [568]

Answer:

The P generation has straight wings and curly wings.

The F1 generation has all straight wings.

The F2 generation has straight wings and curly wings.

Explanation:

This question involves a single gene coding for wing shape in fruit flies. The allele for straight wings (S) is dominant over the allele for curly wings (s). This means that allele "S" will mask the phenotypic expression of allele "s" in a heterozygous state.

According to the question, the cross follows all Mendel's method of crossing two true breeding parents with opposite traits. Hence, the parent generation (P generation) will be between a truebreeding straight wings parent (SS) and a truebreeding curly wings parent (ss). (See attached image for full cross).

Since the straight wing allele (S) is dominant, all the F1 offsprings will possess straight wings with the genotype: Ss, which is heterozygous.

If this F1 offsprings are self-crossed i.e. Ss × Ss, four possible offsprings in the phenotypic ratio 3 straight wings : 1 curly wing will be produced in the F2 generation. The offsprings will possess the following genotypes: SS, Ss, Ss, and ss.

Offsprings SS, Ss, and Ss will all be phenotypically straight-winged

Offsprings ss will be phenotypically curly-winged.

In overall, this means that P generation has both straight and curly wings (SS and ss), F1 generation has only straight wings (Ss), F2 generation has both straight and curly wings (SS, Ss and ss).

Which of the following is a method used to prevent soil depletion?

ratelena [41]

The best method used to prevent soil depletion would be contour farming.

In contour farming, the land is tiled in consistent elevation. Contour farming is efficient in reducing soil depletion because it can conserve rain water and reduce the erosion of soil.

If there is no contour farming in your option, then choose A. Adding fertilizer.
