Control group doesn't change any way.
Answer:
Yellow seed colour (heterozygous)
Explanation:
Since we are performing experiment on the garden pea, so in the garden pea Yellow seed color is dominant and green one is recessive.
The allele responsible for the seed colour is denoted by Y.
So,
Homozygous parent having Yellow seeds will have allelic configuration as YY and the other homozygous parent with green seeds will have yy as pair of alleles.
In the cross of YY × yy the F1 progeny will be Yy which means F1 offspring will will be heterozygous and have Yellow seed colour because Yellow seed colour is dominant over the green colour. Green colour will express itself only in the homozygous condition.
Answer:
Explanation:
When a substance has the capacity to disrupts the genetic compositions (DNA) of the organisms, to the extent that it makes the particular organism genetic materials prone to genetic mutation,( random changes in the genetic composition) such group of substances are called Mutagens.
ionizing radiation,radioactive decay are some examples of of physical mutagens, while biological mutagens examples include viruses and bacterial. Chemical mutagens are Benzene compounds,bromine,aromatic amines,sodium Azide.
They exerts their negative effects
by disrupting gene expression sequence of transcription, translation, or changed the nucleotides sequence of the DNA leading to deletion, addition, subtraction of genetic bases.Some may make chromosomes to be unstable, disrupting the structure
Although some mutagens can cause cancer, that is they are mutagens. not all mutagens carcinogenic.This is because the Mutagenic effects depends on the metabolites present in the cells of the organisms.
Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.
Explanation:
This should be correct.
Conduction
Convection
Radiation
