I need help ! i really don’t get it
Vaselesa [24]

Answer:

The presence of an additional chromosome

Explanation:

Look at "pair" 21. See how there are THREE chromosomes instead of TWO? Normally, there would only be two chromosomes in each pair but this karyotype shows a trisomy (see def. below) of the 21st pair. This was caused by a nondisjunction mutation of the 21st pair. The is also the karyotype of a person with Down's Syndrome.

Definition of Trisomy:

A condition of the presence of three chromosomes in a pair instead of two. This normally causes developmental irregularity.

After photosynthesis, energy that the coral can use is stored in
katen-ka-za [31]

Answer:

Energy is stored in <u>glucose</u> molecules <u>C6H12O6</u>

<u />

Explanation:

Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of <u>photosynthesis</u>. These molecules, like the monosaccharide glucose, store converted solar energy as stable  chemical energy in covalent bonds.  In covalent bonding, the elements share electrons with each other.

These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.

Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).  

Eg. for aerobic respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen →  carbon dioxide+ water+ energy

A population that is decreasing in size will have an age-structure histogram shaped like a(n): 1) inverted pyramid, with a narro
lawyer [7]

The correct answer is - 1) inverted pyramid, with a narrow base representing a small number of young individuals.

The populations that are decreasing are usually population in countries that are highly developed. The conditions for living are excellent, the medical care on high level, life expectancy very high, but the birth rates very low.

In this type of conditions, there's smaller and smaller number of young individuals, with the middle aged population being much bigger, and the older population being constantly on the rise. This will give the age-structure histogram a reverse shape than what it is supposed to have, it will be similar in appearance like a inverted pyramid, meaning that the population is aging and that it will be constantly on a decline in the future.
