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.
A Wisconsin fast plant has 2n= 20 chromosomes
The time that it would take for the population to double is about 7 years.
<h3>What is population?</h3>
The population of an area refers to the number if people that live in that particular area per time. The life expectancy of a population is increased by adequate sanitation. When there is over population in an area, it can lead to malnutrition and decreased food production.
A density dependent factor that affects population growth is disease transmission. The countries with the highest populations in the world do not necessarily have the fastest population growth. One factor that has led to lower fertility rates in Europe and North America is educational opportunity for women.
The occurrence which is not a potential consequence of Earth reaching its global capacity is less spread of disease.
Using;
P= Poe^rt
P = 74,000
Po = 37,000
r = 0.1
Hence;
74,000 = 37,000e^0.1t
74,000/37,000 = e^0.1t
2 = e^0.1t
ln2 = 0.1t
t = ln2/0.1
t = 7 years
