Decomposer's role is to break down dead food. They basically eat it, then the dead food or the dead animal gets ground into the ground, and makes the soil good. Like worms, or fungi, mushrooms, etc. Rotten fruit is not really wasted because 1) the decomposers eat it, and 2) it makes the soil good

Answer:

Explanation:

A food chain is a series of transmission of energy in the form of food when one organism eaten up by another organism. A food web is an interconnection of the food chains.

Decomposers are the organisms, which feed over the dead and decaying parts of the once living organisms. Thus they help in cleaning up of the biological waste from the food web generated after the death of living beings.

The rotten fruit is not truly wasted as the rotten fruit will be consumed by the decomposers. For human beings, the rotten fruit can be considered as the waste and dumped in the garbage but for decomposers it is not a waste, for them it is a source of energy.

1. The main aim of the Human Genome Project was to determine the DNA Sequence of every human gene.

2. Variation in skin colour is an example of polygenic inheritance

This Human Karyotype is unusual because it has an extra chromosome at chromosome 21.

Klinefelters syndrome is shown in the second figure

Explanation:

1. The Human Genome Project's main goal was to sequence all the 30,000 genes and 3 million base pairs in their makeup for the early detection of diseases, gene therapy and molecular level studies.

2. Human skin colour is determined by the pigment melanin. The Dominant allele is responsible for dark colours as it produces more melanin. The melanocortin 1 receptor (MC1R) gene and Tyrosinase enzyme codes for the human skin colour. Polygenic inheritance are the traits which are controlled by one or more genes.

figures:

The extra chromosome at the 21st chromosome pairs is called trisomy 21 or Down's Syndrome. It is due to the abnormal cell division/meiosis resulting in an extra X chromosome. This leads to thechanges the in physical development of the individual.

Klinefelter's Syndrome: There are 47 chromosomes and 2 or more X chromosomes in this syndrome of males. The resulting male suffering from Klinefelter would be sterile and have poorly developed testicles.

Which describes John datiton observations of elements in any given compound

dmitriy555 [2]

Atoms of different elements always combine in the same way.

John Dalton noted that if the components are added to one exacerbated, the share of their masses will dependably be the same. Dalton's been an English scholar. The component mass of that mix is measured by the confirmation of the presence of molecules assembled by John Dalton.
