Denitrification is the process which is responsible for returning nitrogen to air.in denitrification bacteria play an important role they secrete some enzymes which decompose compounds of nitrogen back to free nitrogen.
Answer:
Chromosomes that have the same sequence of genes and the same structure are <u><em>homologous chromosomes. </em></u>
Explanation:
Homologous chromosomes can be described as the chromosomes which carry the same genes at the same loci. They are identical to one another. One of the homologous chromosomes arises from the female and the other one of the homologous chromosome arises from the male during meiosis.
The crossing over between the DNA from homologous chromosomes is the main reason for the wide genetic diversity which occurs due to meiosis.
For example, humans have 23 pairs of homologous chromosomes and one pair of sex chromosomes.
Answer: yes, there will be some organisms that are more suitable to their enviornment than others and they will still reproduce with one another until the less suitable one dies off.
the atmospheric pressure decreases upwards, hence the inter-molecular attraction between the air molecules decreases or to say that the inter-molecular space increases and the parcel of air expands.
It's an animal cell because it doesn't have a cell wall or chloroplasts. It's also not rectanglular shaped. :)
