A chromosome includes diploid sister chromatids (they are in pairs) around a haploid centromere (a singular one) Chromosomes are used in plenty of things like replacing dead skin, creating new body cells, and healing wounds.
Answer:
Difference in their beak size, colour of their feather and body size.
Explanation:
The genetic variation that occurs in the three different species of bird is the difference in their beak size, colour of their feather and body size. The difference of beak size occurs due to difference in their food selection that is available to the birds. Some birds of the population feed on small food particles having small beak size whereas other have large beak size due to preference of large food materials. Some birds have colour like their surrounding that helps them to hide from their predators. Some birds specie have large body size due to availability of more food or due to genetics.
<span>sustainable use would promote the least ecologically damaging manner of extracting resources from delicate ecosystems. Preserving the plants and animals near these sites is instrumental in preserving bio-diversity by not disturbing it in the first place.</span>
Forests is a major part of the biodiversity, forests cover about 6% of the planet, but they harbor up to 90% of the world's terrestrial biodiversity. This biodiversity is irreplaceable, and also has important economic uses. However, forests continue to disappear at an alarming rate. I therefore believe if all rain forests are destroyed then it means about 90% of terrestrial biodiversity will be destroyed.
hope this helps a little :-)
