Answer:

False

Explanation:

Genetic variation is the difference in the sequence of DNA in the individuals of a population and a heterozygote has more genetic variation that homozygote person because heterozygote has two different alleles of a gene while homozygous individual have two same alleles.

Heterozygotes have advantage over homozygotes because it protects the individual from many genetical diseases and increase the genetic variation by increasing the gene pool in the population. So higher fitness results in more genetic variation in the population therefore the statement is false.

Kaylee is making a poster to show changes that happen in nature during winter in northern
kari74 [83]

During the winter season, the tree branches get dormant.

<u>Explanation:</u>

As the winter season starts, many plants show very slower metabolism that is the growth of the plants become very slow.

During the winter, there is very low amount of sunlight that the plants receive and so the synthesis of chlorophyll by the plants also in very small amount, and so there is least amount of sugar to metabolize by means of a slower Photosynthesis.

These tree branches become dormant during winter season, and it is mostly covered with the scales.

A 1 ml sample of culture liquid contained 1000 viable bacterial cells. You serially diluted it twice, performing 10-fold or 1/10
Semmy [17]

Answer:

there are 10 viable bacterial cells in 1 ml in the 1/100 dilution tube

Explanation:

in 1ml there is 1000 viable bacterial cells → diluted with 9 ml of solvent (10 ml in total)→  1000 viable bacterial cells in 10 ml (fist tube)

now we take 1 ml of the first tube into the second empty tube → has 1000/10 = 100 viable bacterial cells on 1 ml → diluted with 9 ml of solvent (10 ml in total)→  100 viable bacterial cells in 10 ml (second tube)

then we take 1 ml of the second tube into the third empty tube → has 100/10 = 10 viable bacterial cells in 1 ml → diluted with 9 ml of solvent (10 ml in total)→  10 viable bacterial cells in 10 ml (third  tube)

therefore there are 10 viable bacterial cells in 1 ml in the 1/100 dilution tube
