Sergeeva-Olga [200]3 years ago
7 0

Answer:

I calculate the buoyancy force as: Volume of the sphere = Volume of the water displaced (Vdisplaced) = (4/3)πr3. Weight of the displaced water = Buoyancy force (B) = Vdisplaced× density of water.

I hope this is what you needed

What is the amount of heat energy needed to raise the temperature of
34kurt

Answer:

25116 J

Explanation:

Q  =  m  ×  c  × ΔT

c = 4.186 J/g°C

M=200 g

So,

Q = 200  ×  4.186 × (40-10)

=200 ×  4.186 × 30

=25116 J

what does the term 2pq represent in the hardy-weinberg equation? the frequency of homozygous recessive individuals the frequency
Nostrana [21]

The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.

<h3>What is Hardy-weinberg equation?</h3>

This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:

p² + 2pq + q² = 1

where

p² is dominant homozygous frequency (AA)

2pq is heterozygous frequency (Aa)

q² is recessive homozygous frequency (aa).

The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.
