The options are:
A.
They are genetically different from the parent because they are produced by sexual reproduction.
B.
They are genetically identical to the parent because they are produced by sexual reproduction.
C. They are genetically identical to the parent because they are produced by asexual reproduction.
D.
They are genetically different from the parent because they are produced by asexual reproduction.
Answer:
The correct answer is- C. They are genetically identical to the parent because they are produced by asexual reproduction.
Explanation:
<em>E. coli </em>reproduces through binary fission in which the genetic material of cell of <em>E. coli</em> first duplicates and then the cell elongates and each of the copies of their genetic material is moved to opposite poles.
After this, the cell gets divided into two equal daughter cells. As binary fission is an asexual reproduction so there is no mixing or combination of genetic material from other <em>E.coli</em> therefore the resultant daughter cells are identical to the parent cell.
Therefore the correct answer is option c.
<span>When the earth spins in a certain direction, the ocean currents move in the opposite direction, sort of like when a car moves forward you are pulled backwards. However, there would still be wind and the gravitational pull of the moon which causes currents. The rotation of the earth just sort of "accents" these. So as a result, you would have many more smaller ocean current cycles.

Answer:
9/16= tall and yellow offspring
Explanation:
Two dihybrid pea plants for color and height are crossed to obtain the progeny. The genotype of both the parents is "TtYy".
Each of the dihybrid parent will form four types of gametes in 1:1:1:1 ratio= TY, Ty, tY and ty. A random fusion of gametes from both the parents would give a progeny in following phenotype ratio=
9 tall and yellow: 3 tall and green: 3 dwarf and yellow: 1 dwarf and green
Answer:
In general, meat-eating carnivores have teeth for tearing and skulls capable of biting with great force, while the plant-eating herbivores have teeth and skulls equipped to grind tough vegetation. Omnivores, which eat both plants and animals, have skulls and dentition suitable for a wide range of foods.
The great/best answer is d. By definition the proportion of false-positive results among those who test positive is 1 minus the positive predictive value. If this number is lower in population A, then population A has a higher positive predictive value. As the disease prevalence increases, the positive predictive value increases. Population A has a higher positive predictive value; therefore, the disease must be more prevalent in population A.
<span>Answer a is not correct since adequate information is provided to infer the explanation for the finding. Answers b and e are incorrect since specificity is a characteristic of a test and does not change when the test is applied to different populations with varying disease prevalence. Answer c is incorrect since the prevalence of disease must be higher in population A as the positive predictive value is higher in population A</span>
