In a certain plant, tall stems (t) are dominant to short stems (t). a farmer crosses a short-stemmed plant with a heterozygous l
melisa1 [442]

The answers would be:

Genotype                Phenotype

     Tt                      Tall stemmed

     tt                       Short stemmed

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2  or 1:1  

<u />

<u>You can read on to see how this was done:</u>

Tall stems (T) are dominant to short stems (t).

First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.

For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.

Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.

Now we can make our Punnett Square.

tt x Tt

<u>       t        t  </u>

<u>T |  Tt  |   Tt</u>

<u>t  |   tt  |   tt</u>

Let's list down the genotypes and phenotypic results.

Genotype        no.         Phenotype

     Tt                 2           Tall stemmed

     tt                  2           Short stemmed

So from that we can answer the other questions:

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2  or 1:1

Birds and mammals have a four-chambered heart, but most reptiles have a three-chambered heart. How does this fact affect the con
eduard

Answer:

The animals present body structure is due to evolution. It is seen in each part including the structure of the heart. The vertebrate heart becomes complex from a simpler form.  

Invertebrates, the heart of fishes is two-chambered having one auricle and one ventricle. The deoxygenated blood gets purified in the gills. They are aquatic and no lungs for breathing. The hearts pump a mixture of oxygenated and deoxygenated blood to the body.  

The amphibians and reptiles have 3 chambered heart as they lead terrestrial mode of life. The gills modified into the lungs.  The left auricle receives pure blood and the right auricle receives deoxygenated blood. The blood purified in the lungs and in the ventricle, both types of blood get a mix. The ventricle pumps the mixed-blood throughout the body.

In the case of birds and mammal, the heart is 4 chambered and the oxygenated and deoxygenated blood are separated. These two are higher vertebrates. No mix of pure and impure blood, the body receives only the oxygenated blood.

This shows to construct the phylogenetic tree of vertebrates - the fishes should be in the bottom, and above it amphibians, reptiles, then, mammals and birds on the top branch of the tree. As the chambers and structure of the hearts modified one after another.

If data point is way off the trend line which of the following will NOT help resolve the problem?
Vlad [161]
The thing that will not resolve the problem of your data is discarding the data point - A

The reason why this won't help is because this data point will still be present just not visible from your data. This is an issue because someone may think that if a data point isn't there that it also means everything is k with the data.

All of the organs have different functions.... very different.

Humans can survive without some of our organs, such as a kidney, gall bladder, etc.

And only a certain number of organs can make up the respiratory system.
