Why a red blood cell burst when placed in water yet an onion epidermal cell does not?​

Biology
1 answer:
xxTIMURxx [149]3 years ago
3 0

Answer:

Hope it helps

Explanation:

The oncotic pressure inside the cell will be greater than the pressure outside. Thus causing the cell membrane to rupture. If red blood cells are placed in pure water, water enters into the red blood cells by osmosis and the red blood cells swell up and burst while the onion cells would absorb water due to osmosis, swell and become turgid.The cell sap move conc. than surrounding water gate into the cell by osmosis; the cell swells/becomes turgid; but does not burst due to the cell wall.

In pea plants, the allele for green pods is dominant over the allele for yellow pods. A plant that is heterozygous for the green
shepuryov [24]

Answer:

Mendel's first law of Segregation of Gametes says that "The alleles of a given locus segregate into separate gametes during meiosis"

Explanation:

The two alleles of a gene pair separate from each other during the process of meiosis and each gamete have an equal probability of producing either allele of the gene.

One parent pea plant is homozygous for inflated pods and green (suppose GGII) which is dominant in nature. Another parent pea plant is homozygous for deflated pods and yellow (suppose ggii) which is recessive in nature.

•) Then both the homozygous parent plants (GGII and ggii) which are dominated and recessive are crossed.

•) The gametes which will be obtained are GI and gi.

•) The resultant progeny is heterozygous with dominant traits GgIi.
