Answer:
b. The herbicide-resistance gene is cloned into the T-DNA region of the Ti-plasmid.
Explanation:
Ti-plasmid has the ability to introduce part of its DNA (t-DNA) into the genome of host plants. This is very important for the relationship of genetic manipulation in maize plants, with the aim of inducing a gene that promotes herbicide resistance. In addition, T-DNA has many genes that code for the production of plant growth phytohormones, which is extremely important for the cloning process to work. In this case, we can assume that the correct answer for yours is the letter B.
Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"
A) complete dominance
B) incomplete dominance
C) codominance
D) epistasis
E) incomplete penetrance
Answer:
B) incomplete dominance
Explanation:
Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.
For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".
Answer:
your answer is antibodies reacting to foreign antigens.
The leakiest capillaries, which allow large substances such as cells to cross the capillary walls are called sinusoidal capillaries.
Sinusoidal capillaries are a unique kind of capillaries that are wide in diameter. The diameter of a sinusoidal capillary is 30 to 40 nm.
Sinusoidal capillaries can be found in the liver, spleen, and bone marrow. In the spleen, sinusoidal capillaries help in the filtration of blood. They remove broken red blood cells, antigens and other pathogens remains in the blood.
Sinusoidal capillaries are known as leakiest capillaries because all other capillaries have a narrow diameter and do not allow the passing of large substances. Sinusoidal capillaries are the only ones with a large diameter that allows the passing of larger substances.

Answer:
Image result for one example in how a bunny rabbit can sense and respond to change
If a rabbit's ears are facing forward, it might hear a noise that makes it feel happy or curious. If its ears are pressed down against their body, it may hear something that annoys it or makes it feel sleepy, like soft music. Another way they change is if its a wild rabbit its fur can turn white during the winter time so that they blend in with the snow around them. I hope that this helps you.
