Answer:
Transcribing the lacl sequence
Explanation:
lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.
However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.
Both Jenny and Jack are correct.
Explanation:
According to the principle of superposition, both Jenny and Jack are perfectly correct.
The principle of superposition states that the oldest bed is at the bottom and the youngest is on top in an undeformed sequence of rock strata.
From this principle we can see that the sequence of the bed is:
- soil Youngest rock layer
- loam
- sand and gravel
- loam
- clay
- impermeable rock (limestone) Oldest rock layer
We can see that truly the clay is older than the sand and gravel according to Jenny.
The limestone is also older than loam according to Jack.

I think it would be c. 1.5 because it is half the size. Also good luck for your quiz
Answer:
At a thermoneutral ambient temperature, cooling either thermode increased oxygen consumption. In a cold environment, cooling either thermode increased the rate of oxygen consumption more than at a thermoneutral temperature. Heating either thermode tended to decrease oxygen consumption in a cold environment. 3.
Explanation:
It flows through the consumers (first level second level so forth). However, at each level, it loses 90 percent of the energy as heat. So at each level, each consumer will only get 10 percent of the energy.
