Answer:
During fertilization, two gametes from the parents —with different genetic information— join together to obtain a unique offspring, different from the parental cells that gave rise to it.
Explanation:
Gametes are the cells produced by each individual to transmit their genetic information to their offspring.
The process of producing gametes is called gametogenesis, and it is a reductive division called meisois. During meiotic division, crossing over occurs, allowing the recombination of genes, which results in genetic variability.
What makes the offspring different and unique from the parental generation is that, during fertilization, the genetic characteristics of both parents are mixed when two gametes are joined.
Answer:
Enzymes help break down larger molecules like fats, proteins and carbs into smaller molecules that are easier to absorb across the small intestine.
Answer:
petiole
Explanation:
The petiole is a stalk that connects the blade with the leaf base.
Answer:
A) It is the recognition site for a specific transcription factor
Explanation:
Promoter is non-coding DNA sequence responsible for initiation of transcription, as a first and most import step in the regulation of gene expression. Usually changing of promoter nucleotide sequence can lead to loss of promoter function.
In eukaryotic cell, promoter is associated with with other regulatory regions such as enhancers, silencers, insulators. The structure of eukaryotic promoter includes the binding site for the enzyme RNA polymerase, site for the binding of regulation factors (such as TATA box), the transcription start site.
