5. The F2 generation of a cross between a parental tall and a parental short pea plant is 298 tall plants and 102 short plants.
Vadim26 [7]

Answer:

The answer is XX.

Explanation:

Let us say that X is the dominant gene and x is the recessive gene for the height of the pea plants. Pea plants need to be homozygous or heterozygous  to have the short phenotype which means it needs to have the genotype xx or Xx.

The F2 offspring has a ratio of 74,5% tall plants and 25,5% short plants. For these results, the stem height pea plant needs to be homozygous which is an XX genotype for the tall pea plant.

I hope this answer helps.

How many times larger is a eukaryotic cell than a prokaryotic cell
jek_recluse [69]

Answer:

The eukaryotic cell is 10 to 100 times larger than the prokaryotic cells.

Explanation:

The eukaryotic cell is 10 to 100 times larger than the prokaryotic cells. The prokaryotic cells are primitive, simpler in structure. The eukaryotic cells are complex in structure and have different adaptation for various cellular activities.  

All the cells have cytoplasm, cell membrane, nucleus. In prokaryotes, the nucleus is not well defined and no other membrane-bound organelles.

e.g. bacteria, archaea.

The diameter of prokaryotic cells is smaller than the eukaryotic cells. Because the transport of ions and cell division is faster in it. Its diameter ranges from 0.1 micrometers to 5.0 micrometers. While eukaryotic cell diameter is 10 to 100 micrometers.  

The small size of the prokaryotes is an advantage to its cellular processes whereas the eukaryotic cells are larger.  Because it has to adapt to the function of different cell organelles present in it.

Can someone do this quick?
kakasveta [241]

Answer: A.

Explanation:

Palisade mesophyll cells contain the most amount of chloroplasts with an average of 30–70 chloroplasts per cell so they will be number 2 in the graph.

Spongy mesophyll cells contain less chloroplasts than their palisade counterparts to enable them have a larger surface area for gas diffusion.

The guard cells have the least amount of chloroplasts on average and so will be number 1. on the graph.

A person is told to take 1.25 mg of vitamin d daily. how many 0.125-mg tablets should this person take?
vovikov84 [41]
This is a simple calculation involving drug doses.

The solution is as follows:

(0.125 mg/tablet)(n) = 1.25 mg
n = (1.25 mg)/(0.125 mg/tablet)
n = 10 tablets

So a person needs to take ten 0.125 mg tablets of vitamin D to have that 1.25 mg dose.
