Answer: The correct answer for the fill in the blank is osmosis.

Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute is lower to a region where the concentration of solute is higher though a semipermeable membrane.

In other words, it is the water movement from an area where its ( water ) concentration is higher to an area where its concentration is lower.

This process does not require any energy as water is moving along the concentration gradient.

The movement of water, from greater to lesser, through a membrane is osmosis. Particles and gases move by diffusion,

Can someone help me with this?

kondaur [170]

Answer:

For Question 9 I'm not sure if you were taught in class but there is a chart to use called a Punnett square.

Explanation:

So for Question 9 use a Punnett square. Then Question 10 should be something about the mixture because since its a black and tan cat being mixed to make a tabby patterned cat you have to in your own words describe the mix. Hopefully this helps good enough.

4. What genotypes of parents will have only white-fur offspring? Parent 1 genotype = Parent 2 genotype = What genotypes of paren

AnnZ [28]

Answer:

All white offspring: Parent 1 genotype = homozygous dominant

Parent 2 genotype = homozygous/heterozygous dominant

For all black offspring: Parent 1 genotype = homozygous recessive

Parent 2 genotype = homozygous recessive

Explanation:

The cross was between a white mouse and a black mouse and the phenotypic ratio of the resulting offspring is 50% white and 50% black.

Assuming that fur color in the mouse is represented by the allele A (a), In order to give 1:1 phenotypic ratio of the offspring, it means the white mouse is heterozygous with Aa genotype and the black mouse is homozygous with aa genotype. Also, it means that the allele A is dominant over the allele a.

Aa x aa

Aa Aa aa aa

Aa = white

aa = black

Ratio of white to black = 50/50 or 1:1

Hence, in order for a cross to yield only white offspring, the parents can either be homozygous AA and AA or one will be homozygous AA and the other will be heterozygous Aa.

1. AA x AA

AA AA AA AA (all white offspring)

2. AA x Aa

AA Aa AA Aa (all white offspring).

In order to produce only black offspring, both parents must be homozygous aa.

aa x aa

aa aa aa aa (all black offspring)

Why are common names a problem for scientist?

Bess [88]

It can be confusing because it isn't specific enough. In astronomy, the big dipper is not a spoon. It is a bear. Scientists know it as Ursa Major rather than a dipper or bear.
