Biology
1 answer:
Fed [463]2 years ago

Answer:

h - height

Explanation:

gravitational potential energy = m * g * h

m stands for mass. Mass doesn't change in physics

g stands for gravitational acceleration. It is a constant.

h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.

The diagram shows a normal red blood cell and a shrunken red blood cell, both of which are in salt water.
bixtya [17]

Answer: Water moved from inside the red blood cell into the salt water.

This is because of the osmotic difference between the salt solution and the red blood cell. This means that there is difference in the solute (salt) concentration inside the red blood cell and the salt solution.

Explanation: The salt concentration in the solution is higher than the salt concentration inside the red blood cell, that is, the red blood cell has more water concentration that the salt solution, therefore there will be movement of water from the inside of the red blood cell into the salt solution thereby causing the red blood cell to reduce in size. The movement of water from the red blood cell into the salt solution is to create a balance between the water concentration in the two environments, hence the movement of water from an area of high water concentration to an area of low solvent concentration across the selectively permeable membrane of the red blood cell.

If you sorted 200 flies by eye color and body color, how many whole flies out of that 200 would you expect to exhibit each of th
mafiozo [28]

9:3:3:1 is the ratio.

From the given data,

We have a 9.8 two, ratio since we have 49/5, 15/5, 18/5, and 5/5.

This ratio resembles nine a little bit, which is what we inferred from the opposition's score.

When the two relevant genes exhibit independent assortment, this is the result. Therefore, the chromosomes/genes are not connected.

We are finally getting a ratio of 9:3:3:1

In flies, two possible outcomes for the body color phenotype is black and brown.

Whereas in eye color we have white eye and red eye.

Here, white eye is recessive and red eye is dominant

<h3>What does the independent assortment law entail? </h3>
  • According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes.
  • In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.

<h3>Where can I find independent assortment?</h3>
  • Meiosis I of gamete production, when homologous pairs line up in random orientations at the center of the cell as they prepare to split, provides the physical foundation for the law of independent assortment.
