Answer:
Cellulose
Explanation:
Cell walls made of cellulose are only found around plant cells and a few other organisms. Cellulose is a specialized sugar that is classified as a structural carbohydrate and not used for energy. ... While cell walls protect the cells, they also allow plants to grow to great heights. You have a skeleton to hold you up.
I'm sorry but there is no photo attached to it
The result will be two new properly formed strands of replicated DNA.
Answer:
Explanation:
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
The answers would be:
In Mendel’s crosses, the <u>recessive </u>trait is visible in the F2 generation, but not the F1 generation.
After crossing a tall pea plant with a short pea plant, all of Mendel’s pea plants were tall because it is the <u>Dominant</u><u><em> </em></u>trait.
For seed color, the F2 generation produced both yellow and green seeds because there are two different <u>alleles </u>for each gene.
If you'd like to know more, read on:
Alleles are variants of genes that control traits. There are two alleles called the dominant and recessive allele.
A dominant allele is a trait that is physically expressed even when coupled with a recessive allele. A recessive allele on the other hand is the trait that is masked by the dominant allele.
This is what happened in Mendel's crosses. He crossed a true-breeding tall plant with a true breeding short plant.
P generation
TT - Tall plant
tt - Short plant
The result in the F1 generation that consisted only of Tt plants, where the dominant allele was expressed.
T T
t Tt Tt
t Tt Tt
Then he crossed the F1 generation to produce the F2 generation.
Tt x Tt
The results:
T t
T TT Tt
t Tt tt
As you can see the resulting offsprings shows that the recessive trait occurring, tt. This means that there was a 25% chance that the off springs produced would short plants and 75% that the offsprings produced is tall. This applies also to the color of the seeds if we cross the pea plants based on the color of seeds.
