I fail to see your question. Do you mean "How is sex determined in mammals?"
One X chromosome is donated by the female, then either an x or y chromosome is donated by the male.
Answer:
Higher Photosynthesis, lower carbondioxide concentration in the atmosphere and vice versa.
Explanation:
Photosynthesis is greatly responsible for the fluctuation of carbondioxide concentration in the atmosphere because photosynthesis is the process where carbondioxide gas is used in large amount. If the vegetation occurs higher in the season, decrease will occur in the carbondioxide concentration of the atmosphere while on the other hand, if the less vegetation occur then there is higher amount of carbondioxide concentration in the atmosphere.

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.
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.
