Answer:

if the lacI gene, in the genetically engineered fluorescent strain were non-mutant but the lacO sequence on the chromosome  is mutated to lacOc then,

in the presence of the inducer, the cells fluorescence will show

yellow; red

in the absence of inducer, the cells fluorescence will show,

yellow; no fluorescence.

Explanation:

when lacO is mutated with lacOc then constitutive mutation happens which lets the system to be on.

A student draws a fence with several gate as part of a model of cellular transport explain what defence indicates represent blam
Oksi-84 [34.3K]

The given question says that a student has constructed a model of cellular transport using fences and several gates.  

This model can be used to demonstrate the cellular transport.

The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.  

Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.

Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.

Licemer1 [7]

Answer:

Option 1, No. The highest frequency of heterozygotes under Hardy-Weinberg equilibrium is 0.5

Explanation:

As per Hardy Weinberg’s equilibrium principle, the maximum frequency of heterozytotic individuals occur only when half of the population is dominant and recessive homozygous.  

In other way when the sum of frequency of dominant and recessive species is equal to 0.5, only then the frequency of heterozygotes is maximum which in any case would not be higher than 0.5.  

Hence, option 1 is correct
