Four main classes that define a macromolecules are

Protein
carbohydrates
lipids
nucleic acid

EXPLANATION:

Macro-molecule is a large molecule which can contain more than 100's and 1000's of atoms. They are different from the smaller molecules and each macro-molecule does more than one function.

Macro-molecules are made up of single elements of monomers joined using covalent bonds and a large polymer is formed. For example, one molecule of polyethylene which is plastic has more than 2500 methylene groups, each one of them has two hydrogen and one carbon atoms.

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0. 3. What i

zavuch27 [327]

Here, given-

homozygous alleles 'a' have a frequency of 0.3.

Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.

The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.

Calculation-

$p + q = 1\\0.3 + q= 1\\q= 1- 0.3\\\\q= 0.7$

Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-

$p^{2} + 2pq + q^{2} =1$

$p^{2} = dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2} = recessive homozygous frequency\\$

Thus, the individuals homozygous for the allele can be calculated by $q^{2} = (0.7)^{2} \\= 0.49$

. What causes a hurricane to form will give brainliest to smartest answer

Archy [21]

Answer:

For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.

Explanation:

In short pressure zones over warm ocean
