Answer:
C
Explanation:
A DNA is made up of proteins which was synthesized by ribosomes of the cell to produce mRNA and then these mRNA and used to catalyse the DNA production. DNA of a cell in the nucleus is the programmed individuality that controls, manages and organizes the entire cell to function and initiate celluar activities.
Answer:
Respiratory bronchiole
Explanation:
The respiratory bronchioles represent the narrowest airways within the lung, being continuations of terminal bronchioles that have approx. 0.5 mm in size. The epithelium of the respiratory bronchiole is composed of cuboidal ciliated cells and a small number of non-ciliated (secretory) Clara cells. The respiratory bronchioles lead into alveolar ducts composed of smooth muscle and connective tissue (i.e., elastin and collagen), connecting the respiratory bronchioles to the alveolar sacs.
Answer:
1/4
Explanation:
In order for a plant to be short and yellow, it needs to have hοmοzygous lowercase letters for height and color.
If the plant had one capital letter for either height, color, or both, this would dominate the recessive gene and would not allow the plant to exhibit the recessive trait.
The short, yellow plant has a genotype of:
The plant that is heterozygous for both traits means that its genotype has both the dominant (capital) and recessive (lowercase) letters.
The heterozygous plant has a genotype of:
We can use a dihybrid crossing of alleles in a 4x4 Punnett square. To figure out which four pairs of alleles to use for crossing, we can FOIL the genotypes of the two plants getting crossed.
- (tt) · (gg) = tg + tg + tg + tg
- (Tt) · (Gg) = TG + Tg + tG + tg
Use these pairs of alleles to cross in the Punnett square. To see which offspring will be short and green, we need to look at the pairs of alleles for the height and color traits separately.
Short plants must have the genotype of tt.
Green plants can have the genotype of GG or Gg.
Look at the Punnett square to see which genotypes are hοmοzygous for the short trait and either hοmοzygous or heterozygous for the green trait.
We can see that the third row of genotypes consist of ttGg, which corresponds to the short and green phenotypes.
Therefore, 1/4 of the offspring will be short and green.
Answer:
Probably the 1 million one because it is the closest time or ancestor to the current horse.
