Explanation:
Molecules of reactants and products undergoes chemical changes when they combine.
The combination leads to the breaking of bonds and rearrangement and this brings about the formation of new products.
- Atoms in molecules tends towards stability
- They often want to mimic the noble gases and would keep rearranging until stability is attained.
- This leads to the formation of new compounds in the product end of the reaction.
Answer: mathematics
Explanation:
Mathematics is the study of quantity, space, structure of a concerned entity or population size. A scientific experiment may be based on the analysis of variables must be having large sample size. Therefore, quantitative estimation of the results is required. Hence, a scientist requires mathematics to interpret the results of a scientific experiment.
Answer:
1/2 or 50%
Explanation:
This question involves a single gene coding for the number of digits per paw in cats or humans. The allele for polydactyly i.e six digits (P) is dominant over the allele for normal number of digits i.e 5 (p).
According to this question, If a man who is heterozygous (Pp) for this trait marries a woman with 5 fingers (pp), the following gametes will be produced by each parent:
Pp : P and p
pp : p and p
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Pp, Pp, pp and pp
The offsprings with genotype Pp will have polydactyl, hence, the chances that they will have a child with polydactyly is 1/2 or 50%.
This organism is a coyote brush or the Baccharis pililaris. It is a shrub that is a family of daisy. They are mostly found in California, Washington and Oregon. This plant takes a different shape depending on the environment where it is found. It grows in a chaparral biome where there is little biodiversity and a habitat of only few species.
