Answer:
Nitrogen fixing bacteria is the organism which is responsible for the fixing of atmospheric nitrogen into usable form for the plant.
Explanation:
Nitrogen fixing bacteria is a type of bacteria which fixes atmospheric nitrogen into ammonium and nitrates form. Plants are unable to take atmospheric nitrogen so it must be converted into available form i. e. nitrates and ammonium. Examples of nitrogen fixing bacteria are Cyanobacteria and Azotobactor etc. These nitrogen fixing bacteria lives in the root of the plant and makes symbiotic association.
Usually it is the x and y chromosomes. XX is for females and XY is for males. That is how gender is determined in most living things. Hope this helps!!
Answer:
The genotypes thatwould be considered pure breeds are BB and bb
Explanation:
The genotype of an organism refers to an organism's complete set of genetic material or genes.
Genes are units of DNA that carries information for a particular physical or functional trait or character in an organism. Some genes act as instructions to make proteins while some genes do not code for proteins. The proteins made by a gene expresses the traits and characters of that organisms. Genes for a particular trait may have one or more variants known as alleles.
In Gregor Mendel's research using pea plants, flower colour in a pea plant had two different alleles; one for red flower colour and one for white flower colour. If a plant had the same allele for flower colour, the plant was considered a pure breed.
For example, given B was the allele for red flower colour and b was the allele for white flower colour, a plant having the two alleles for white flower colour bb, is a pure breed. Similarly, a plant having the two alleles for red flower colour, BB is a true breed.
Answer:
Canceled out
Explanation:
In a negative feedback loop, the product of the loop inhibits whatever initiated the loop, preventing more product from being formed.
This is in contrast to a positive feedback loop, where the product of the loop further stimulates whatever initiated the loop, resulting in even more product being formed.
