Answer:
Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.
Explanation:
- There are two types of speciation: allopatric and peripatric.
- Allopatric speciation occurs when the species of same population gets isolated that results in lack of gene flow.
- From the isolated population, new species are formed then it is known as the peripatric speciation.
- All these isolation of populations and formation of new species depends upon the initial or original group of species that was dispersed.
Answer:
%50
Explanation:
Heterozygous = 2 different alleles (Tt)
4 leaf clover = 2 recessive alleles (tt)
T is dominant over t, so with the combination of Tt three leaves are expressed, rather than four leaves
For a recessive trait (four leaves) to show 2 recessive alleles are needed
To find the percentage of the offspring to have four leaves a punnet square should be created
To find the percentage divide the number of four leaf offering with 4 and multiply by 100
2÷4×100=50
= 50%
Answer:
C. use battery with less voltage.
Given: Drug medications are often prescribed on the basis of body mass. the adult dosages of elixophylin, a drug used to treat asthma, is 6mg/kg of body mass.
To find: The dosage amount for a person weighing 160 lb.
Method: Unitary method of proportions
Solution:
First we'll convert the weight of person from imperial unit to metric unit.
1 pound = 0.45 kilograms
160 pounds = 0.45 x 160 = 72 kg
∴ The weight of person in kilograms is 72 kg.
Now, a elixophylin dosage of 6 mg is administered to 1 kg body mass.
For 72 kg body mass, dosage will be,
= 432 mg
∴ The person of 160 lb body weight will receive 432 mg of elixophylin dosage.
