Answer:
Explanation:
Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. Ecosystem diversity is a type of biodiversity. It is the variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.
Organisms on a island are more similar to those on a nearby land mass than to those in similar climates further away.
Answer:
Air pollution would most likely trigger climates change.
Explanation:
Poor air quality can lead to fires, diseases, and higher air temperature
Answer:
3/4 taster; 1/4 non-taster
The likelihood that their first child will be a taster: 75 %
Explanation:
Complete dominance occurs when a dominant gene variant or 'allele' completely masks the expression of the recessive allele in heterozygous individuals (i.e., individuals carrying one copy of the dominant allele and one copy of the recessive allele). In this case, both parents are heterozygous for a single gene trait (i.e., the ability to taste) which is ruled by complete dominance. In consequence, the expected phenotypic ratio in the progeny (F1) will be:
- Alleles: T (dominant taster allele); t (recessive non-taster allele)
- Parental cross: Tt x Tt
- Punnett Square from this cross:
T t
T TT Tt
t Tt tt
Expected F1 phenotypic ratio: 3/4 taster (i.e., 1/4 TT genotype + 1/2 genotype Tt = 3/4 or 75%); 1/4 non-taster (tt genotype = 1/4 or 25%). Moroever, the chance that the first child has the taster phenotype is 3/4 (75%).
The definition of transformation in bacteria is described by the first statement: transformation is the assimilation of external dna into the bacterial cell. In a more elaborate sense, transformation is described by the altering of the cell as a result of the uptake or intentional incorporation of dna from an external source. It is one of the three processes for horizontal gene transfer. The other two are transduction (infection of a phage), and conjugation (transfer of dna between two bacterial cells that are directly in contact).
