For a species of beetle, n = 20, a diploid cell would contain 40 chromosomes overall.
<h3>How do chromosomes work?</h3>
A chromosome is a long DNA molecule that houses all or some of the genetic code of an organism. In order to preserve the quality of the chromosome, chaperone proteins and histones, a type of packaging protein present in the majority of eukaryotic chromosomes, attach to and condense the DNA molecule.
<h3>What place do chromosomes come from?</h3>
The DNA that makes up each chromosome has been continuously tightly coiled around proteins called histones to support its structure.
<h3>Which of the four chromosomal kinds:</h3>
- Sub metacentric chromosomes.
- Chromatin that is acrocentric.
- The telocentric chromosomes.
- Chromatin that is metacentric.

Answer and Explanation
Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.
He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.
He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.
He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.
Answer:
The enzymes will be activated and enzymatic reaction will start.
Explanation:
Co-factors are substances that need to be present in order for enzyme activity.
Answer: Sensory mechanisms are responsible for detecting the external stimuli present in the environment.
Explanation:
The sensory mechanisms help people to observe things around them through eyes, they can hear the sounds through their ears, they can feel the insect creeping on their skin by touch sensory mechanism, they can taste food which they cook through taste or gustatory receptors present on tongue and other parts of mouth cavity.
