I can conclude that this plant will follow the same traits of its parent plants, and will reshape to be a full new plant.

Uh...that it will have the same genetic makeup as the plant it came from? or that it's asexual? dont really know what u need here.

1. What type of response will a red blood cell have when placed in a hypertonic solution?
GalinKa [24]
Hypertonic solution means the solution with a lower water potential than the cell cytoplasm, such as salt water.

When the red blood cell is put into it, since the cell has a higher water potential than the solution, water molecules will flow from the cell back into the water due to osmosis.

Osmosis is always where water molecules flow from a region of higher water potential to lower, through a semi permeable membrane (Whcih is the red blood cell membrane in this case.)

Since water flowed out of the cell, the cell lose water and shrinks.

Hypotonic solution is where the solution that has a higher water potential than the cell cytoplasm.

So when the red blood cell is put in that solution, the water will flow from the solution into the cell this time, by osmosis.

The red blood cell will then gain so much water that the cell membrane cannot hold all and therefore burst.

What statement accurately compares sexual and asexual reproduction?
Advocard [28]

Answer:

Sexual reproduction results in genetic variation and asexual reproduction does not.

Explanation:

The key difference between sexual and asexual reproduction is that sexual reproduction occurs between two parents while asexual reproduction occurs via a single parent. Asexual reproduction requires only a single divisible cell to produce a new organism, whereas sexual reproduction requires two gametes, their formation and fusion.

_____________ and __________ are the components of ribosomes. A) DNA and RNA B) RNA and protein C) Ribose and amino acids D) Mic
yanalaym [24]

Answer: The correct answer for the fill in the blank is B) RNA and Proteins.

Ribosome is a molecular machinery, which is located in all living cells. It is formed from proteins and complexes of rRNA ( ribosomal RNA). That is why, it is also called as ribonucleoprotein.

Ribosome serves as the site for protein synthesis. It is primarily divided into two subunits, a larger ribosomal subunit and a smaller ribososmal subunit, which together assist the process of protein formation ( translation).

Thus, the components of ribosomes are RNA and proteins.

People who are tune deaf are unable to follow a rhythm. Scientists have evidence that tune deafness can be genetic. The pedigree
butalik [34]

Question

Pedigree attached

a. Provide evidence from the pedigree that conclusively shows that the tune deafness allele is autosomal dominant, not autosomal recessive. Explain your reasoning.

b. Identify the genotypes of individuals 5 and 6, and then draw the Punnett square for the cross of these two individuals.

c. Compare the expected percentage of each phenotype of the offspring from the cross in part (b) with the actual percentage of each phenotype observed in the children of individuals 5 and 6.

Answer/Explanation:

a. Autosomal dominant means that even having one copy of the allele T will produce a tune deaf individual. The evidence of this is that individuals II.3 and 4 have children (III. 8 and 9) with normal tune perception. This suggests that they have inherited the normal allele from both parents. That means II.3 and II4 must be heterozygous, in order to pass on the normal allele. This makes sense if tune deafness is dominant (because 3 and 4 will both be Tt and Tt, so can pass on the t alleles). However, if tune deafness was recessive, that would mean that individual II 3 and 4 both have to carry 2 copies, meaning there is no way their children would have normal tune perception.

b. Since individual 5 is unaffected and we know this is the recessive trait, they must be Tt. Since individual 6 is affected, they must be either Tt or tt. However, they have children who are unaffected (11, 12, 13) who must be tt. This means, individual 6 must have the t allele to pass on, and must be Tt. Therefore, the cross between individuals 5 and 6 is tt x Tt:

         T        t

t        Tt       tt

t       Tt       tt

c) The punnet square shows the children from (b) have a 50:50 chance of being tune deaf vs normal tune perception (50% each). In contrast, the actual ratios are 25% tune deaf to 75% normal tune perception. (1:4). This deviates from the expected ratio, but since all of these are due to chance, it is not an unexpected occurrence. Perhaps if there were 10, 50 or 100 children (!) from this cross, the results would be more like the expected ratio
