Answer:
I think first one i don't really know
Explanation:
Answer:
The answer isn't on there, but humans have estimated 20,000-30,000 genes.
<em>The</em><em> </em><em>closest</em><em> </em><em>answer</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>selection</em><em> </em><em>is</em><em> </em><em>"</em><em>Twice</em><em> </em><em>as</em><em> </em><em>many</em><em> </em><em>as</em><em> </em><em>A</em><em>"</em>
Explanation:
The HGP has revealed that there are <em>probably about </em>20,500 human genes. This ultimate product of the HGP has given the world a resource of detailed information about the structure, organization and function of the complete set of human genes.
Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins. Each of the <em>estimated </em>30,000 genes in the human genome makes an average of three proteins.
a. In the lag phase, cell death exceeds cell division. FALSE
Is the period when the bacteria are adjusting to the environment.
b. In the death phase, bacterial growth may cease as a result of oxygen and nutrient depletion. TRUE
Is characterized by an exponential decrease in the number of living cells.
c. Bacteria typically divide by binary fission, producing two daughter cells. TRUE
This is the most common way of division. The duplicate's DNA and part in half.
d. The generation time of bacteria may vary from species to species. TRUE
As in all species, the generation time will always vary.
