1- free water
2- Solute
During osmosis, water diffuses across a selectively permeable membrane from the region of higher _______ concentration and lower _____ concentration to the side with lower _______ concentration and higher _______ concentration
.
Answer:
During osmosis, water diffuses across a selectively permeable membrane from the region of higher free water concentration and lower solute concentration to the side with lower free water concentration and higher solute concentration
Explanation:
Osmosis is a biological process that takes place in cells and allows a substance to pass through the plasma membrane. Through osmosis, the plasma membrane, water can pass into and out of the cell through a gradient of solute concentration, that is, water passes from the place with the lowest concentration of solute to the place with the highest concentration, allowing thus the balance between the inter and extra cellular medium.
The scratch test.
The scratch test is used by scientists and people who study rocks and minerals to determine the strength of the rock. They have the scratchers numbered one through ten and scratch the rock or mineral until the scratcher makes a mark in the mineral then they know the strength of the rock.
Answer:
Genotype of the parental plant that produced round, yellow seeds is RRgg
Explanation:
Let us say that allele for round shape (R) is dominant over allele for wrinkled shape(r)
and allele for green color (G) is dominant over allele for yellow color of seed.
So a wrinkled green seed will have genotype either "rrGG" or "rrGg"
Like wise a round, yellow seeds will have genotype either "RRgg" or "Rrgg"
It is given that In the F1 generation, half of the plants produced round, yellow seeds and the other half produced round, green seeds.
So if a cross is carried between rrGg and RRgg, the following offspring will be produces
rG rG rg rg
Rg RrGg RrGg Rrgg Rrgg
Rg RrGg RrGg Rrgg Rrgg
Rg RrGg RrGg Rrgg Rrgg
Rg RrGg RrGg Rrgg Rrgg
So genotype “RrGg” gives round and green seeds
And genotype “Rrgg” gives round and green seed
Thus, genotype of the parental plant that produced round, yellow seeds is RRgg
I think that the answer would be C
The correct answer is option B, 50%
Let us take the following case:
Genotype of heterozygous parent - (Aa)
Genotype of homozygous parent – (aa)
Allele I - (Aa)
Allele II – (aa)
The cross between the two is shown below:
Aa X aa
Aa, Aa, aa, aa
There are 50 % Aa, and 50 % aa allele.
Thus, the allele I (Aa) is 50 %.
