Gregor Mendel crossed true-breeding plants with green pea pods with true-breeding plants with yellow pea pods. The resulting F1

generation all had green pea pods. What did he observe in the F2 generation?
A. Mendel observed green and yellow pea pods in a 3:1 ratio because the F1 generation was heterozygous.
B. Mendel observed green and yellow pea pods in a 4:1 ratio because the allele for green pea pods is dominant.
C. Mendel observed green and yellow pea pods in a 1:1 ratio because the F2 generation had the same characteristics as the parent generation.
D. Mendel observed only green pea pods because both parents had green pea pods.
E. Mendel observed green and yellow pea pods in a 1:2 ratio because the allele for yellow pea pods is dominant.

Answer:

A. Mendel observed green and yellow pea pods in a 3:1 ratio because the F1 generation was heterozygous.

Explanation:

The two true breeding plants in the parental population were homozygous (that is what true breeding means). Therefore, their cross would lead to all heterozygous offspring (see attached punnet square). Green is the dominant characteristic, so all F1 plants had a green phenotype, but Gg genotype.

The F1 cross would therefore be Gg x Gg. See attached punnet square.

The genotypes in the F2 generation are 1 GG: 2 Gg: 1 gg 1

Therefore, the phenotypic ratio is 3 green pea pods (Gg or GG): 1 yellow (gg)

Red blood cells,carrying dioxide(a waste product of cellular respiration) travel in the blood vessel to the lung; to get rid of
alexandr1967 [171]

Answer:

True.

Explanation:

Red blood cells or erythrocytes carry oxygen to the cells of the body so that they can have energy and function properly. This is not the only function of red blood cells. Also, they carry dioxide, which is a waste product that needs to be out of our body. Erythrocytes carry the dioxide to the lungs, specifically to the alveoli. In the alveoli due to the inhalation, oxygen enters our body traveling up to the lungs, specifically to the alveoli, where thanks to the thin wall of it as well as the one on the capillaries that are in contact with it, the dioxide enters the lungs to be expelled in the exhalation, and the oxygen is taken by the red blood cells to be used in the cellular respiration and generate energy to keep the vital functions of our body.

During the late cretaceous, the bisti badlands were home to numerous animals including turtles, crocodiles, and even dinosaurs.
vaieri [72.5K]
These animals were living in an environment with a warm climate that results in changing sea levels. These conditions create a lot of shallow inland seas allowing these animals to thrive. The Cretaceous period is the last period of the Mesozoic area where new groups of mammals, birds, and flowering plants appeared on Earth.
