Answer:
A cross between two pure breeding tall (TT) and dwarf (tt) parent plants produce uniform F
Explanation:
generation of dominant individuals (Tt).
According to the law of dominance, a trait is represented by two contrasting factors of a gene in a heterozygous individual; the allele/factor that can express itself in a heterozygous individual is called as a dominant trait. Another factor whose effect is masked by the presence of a dominant factor is called a recessive factor. The recessive factor, t, is present in F
hybrids but its expression is masked by the factor for a dominant trait, T.
Answer:
competition, predation, commensalism, mutualism and parasitism.

Hi
There are two types of fermentation:
- Lactic acid fermentation
- Alcoholic fermentation
Both of them are basically methods of anaerobic respiration in
Lactic acid fermentation occurs in some bacteria and in some tissues of animals( like skeletal muscles and Red blood cells). In this process glucose is converted into energy and a by product called Lactate is formed. This type of fermentation is also used in food and brewing industry where lactic acid bacteria are used for the synthesis of different products.
Alcohol fermentation on the other hand is used by some microorganisms like yeast for the production of energy. The byproduct that is formed along with ethanol.
Hope it helps!
Scientists have recently modified the bacteria that cause tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid. This new DNA is called recombinant DNA.
<h3>What is recombination DNA?</h3>
Genetic recombination is the exchange of genes between two DNA molecules to form new combinations of genes. Like mutation, genetic recombination contributes to the genetic diversity of a population, which is the source of evolutionary variation.
Bacteria have two mechanisms of genetic variability: mutation and gene recombination. Gene recombination occurs by three types of mechanisms: transformation, conjugation and transduction. Transformation is the incorporation of free DNA by the bacterial cell.
