Explanation:

(3) active transport

The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.

While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.

Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.

yawa3891 [41]

Answer:

It will cause an Aneuplidy , an abnormal number of chromosomes that cause a fail on the chromosomes to separate at meiosis.

Explanation:

Abnormalities in chromosome number are the most obvious chromosomal disorder and are referred to as aneuploidy. It`s a condition in which one or more chromosomes are present in extra copies or are deficient in number, but not a complete set.

The loss of a single chromosome from a diploid genome is called monosomy and the gain of one chromosome is called trisomy, caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis.

Misaligned or incomplete synapsis, can cause nondisjunction.

The risk of nondisjunction increases with the age of the parents.

I hope it helps!
