Larger
During the process of breathing, the diaphragm contract by moving
downward and upward and this process usually increase or decrease the space in
the chest cavity. However, intercostal muscles between the ribs also help to enlarge
the chest cavity or reduce the space in the chest cavity.
D. Combination of exercises which the client can enjoy and
likes.
For most people, exercise is a taxing. It’s a lot of hard
work and sometimes the kind of exercise to be done makes it even harder to do.
That’s why it is very important for a workout to be a combination of exercises
that a person likes or enjoys. This may involve plenty of trial and error.
However, most people already have a hobby or a certain activity that they like to
do. To make an exercise or workout effective, it would be best to tap into
their interests.
Answer:
C. The green allele is recessive to the yellow allele
Explanation:
Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.
