<u>Answer</u>: c. Carrying capacity is the maximum population size required for a particular species in a particular area to survive.
<u>Explanation</u>: this is an average population density level. If the population density is above this level, the number of individuals will decrease. If the population density is under this level, the number of individuals will increase until the carrying capacity is reached once more.
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%).
<span>Their pattern of dispersion is the clumped dispersion</span>
The phenomenon is tolerance.
Tolerance can be found in many aspects of physiology,
For example, when you feel a pain somewhere due to touching something sharp, the feel will be less intense when you feel it the next times.
When you eat a lot of sweets, you tung will temporarily lose its ability to feel sugars
Another example in pharmacology, when you drug in a chronic way, its effect will decrease.
