5 factors that affect weather: geographic location/latitude altitude/height above sea level, ocean currents/large lakes, winds,t
Igoryamba

The statement is - True.

The five main factors that determine the weather at a certain place are the:

- geographic location/latitude

It determines the amount of sunlight, as well as the concentration of sun rays, which directly influences the temperature.

- altitude/height above sea level

The lower the place the warmer it is, the higher the place the colder it is, it is a simple rule that applies for all places on the planet, compared with places in their surroundings.

- ocean currents/large lakes

The ocean currents can bring cold and dry or warm and wet air masses, depending on what kind of an ocean current it is. The water also contributes to a more stable weather, with more moderate temperatures because of the thermal properties of the water to cool of and warm up slower than the land.

- winds

The air masses can bring cold and dry or warm and wet weather, so they influence the temperature and precipitation of a place.

- topography

Determines how much a place is exposed to the sunlight and the movement of the air masses.

if there are 500 people in a population, and 150 are homozygous HbA/hba, 150 are homozygous hbs/hbs, and 200 are heterozygous hb
sineoko [7]

Answer:

0.547

Explanation:

Given -

Total Population - 500

Individuals with homozygous HbA/hbA genotype - 150

Individuals with homozygous hbs/hbs genotype -150

Individuals with heterozygous hba/hbs genotype -  200

Let us assume the given population is in Hardy Weinberg' equilibrium

The frequency of individuals in the given population with homozygous HbA/hba genotype is equal to number of individuals with homozygous HbA/hba genotype divided by total population.

\frac{150}{500} \\= 0.3

The frequency of hba allele is equal to

\sqrt{0.3} \\= 0.5477
