Answer:

B) The chromosomes in the cell lack a homologous pair in the same cell

Explanation:

Meiosis is the cellular division that reduces the chromosomal number of the parent cell by half in the daughter cells produced. In a somatic (body) human cell, chromosomes are found in homologous pairs i.e. each pair coming from each parent to form a diploid organism (2n).

However, when meiosis occurs, this homologous pair is separated into individual chromosomes. This is the case of the human cell which contains 46 chromosomes or 23 pairs of chromosomes. Each pair is an homolog of the other, however, meiotic division causes the homologs to separate. This will cause the chromosomes in the cell lack a homologous pair in the same cell.

The two methods in the lab for measuring the volume of a geometric solid object are weighing it on the balance and measuring it

Yakvenalex [24]

Answer:

Measuring with a ruler and using final volume minus initial volume

Explanation:

You can measure the volume of a geometric object by measuring its sides with a ruler and calculating the volume according to the corresponding formula for each object. For example, for a rectangular prism it would be

$volume=length*width*height$

You can also measure the volume of an object by measuring how much water it displaces. To do this you have to fill a measuring cylinder with enough water for the object to be completely submerged and take note of the volume. Then, add the object and note again the volume of the water+object. The difference between both is the volume of the object.

$Volume of the object= volume of water and object - volume of water$

The advantage of the second method is that it can be used for objects with irregular shapes as long as they do not float.
