To know where it rightfully belongs to. Variation of certain traits is caused by multiple factors of an individual of the same kind. Depending on their physical appearance, their environment and nature of survival.
Hope this might help.
Answer:
C. Fi 1:0, F2 3:1
Explanation:
Firstly, Mendel's law of segregation states that the alleles of a gene will randomly separate into gametes during gamete formation. In this case involving a single trait, hence, a single gene. Mendel crossed two purebreeding plants i.e. homozygous plants that produced different phenotypes for the same gene. He obtained his offsprings which he called F1 offsprings. He realized that all the F1 offsprings expressed only one phenotype. For example, when he crossed homozygous tall (TT) and short (tt) plants, he got F1 offsprings that were all tall.
He then self-crossed these F1 offsprings to produce a F2 offsprings that had a phenotypic ratio of 3:1 i.e. 3tall, 1short plant. He concluded that the alleles of the single gene had segregated into the gametes but one allele was capable of masking the expression of another, as seen in the heterozygous F1 offsprings that were all tall (Tt).
Hence, he obtained a 1:O ratio for his F1 offsprings then a 3:1 ratio for his F2 offsprings.
Symbiosis
• A tight relationship of two or more species that are ecologically interdependent and live together in close proximity (symbiosis can be non-mutualistic e.g. parasite-host symbiosis)
Answer:
An allosteric site is a site that lets molecules either activate or deactivate the activity of enzymes
Answer:
Saturated fats/ solid fats
Explanation:
Vegetable oils amongst other unsaturated oils are liquids at room temperature while saturated oils are solids or spreadable at room temperature.
Industrially, vegetable oils are hydrogenated; hydrogenation is the process of adding hydrogen to an unsaturated compound to make it saturated. This then makes these hydrogenated vegetable oil, saturated which makes them solids as earlier stated, they are also called cis - fatty acids.
Trans - fatty acids as well are also unsaturated oils which are hydrogenated industrially to give saturated fatty acids which are called artificial tran-fats. They are found in most commonly found in baked and fried goods.
