Drag the labels to the table below to describe how allele frequencies would be affected under different conditions. remember tha

t p is the frequency of the cr allele, and q is the frequency of the cw allele. labels may be used once, more than once, or not at all.

This the correct answer for this question:
Mutation - p will  increase and q will decrease

Nonrandom mating - frequency of plants with pink flowers will be much less than 2pq

Natural selection - p and q will stay the same

Small population size - changes in p and q cannot be predicted

Gene flow - p will decrease and q will increase

This the correct answers for this question:

Mutation - p will  increase and q will decrease

In this case, "P" is representing homozygosity "Q" is representing genetic variation. Therefore the individuals are further decreasing genetic variation by increasing homozygosity in the genomes of their offspring. Mutation is a weak force for changing allele frequencies but is a strong force for introducing new alleles therefore it is the ultimate source of new alleles in plant pathogen populations. 
Nonrandom mating - Frequency of plants with pink flowers will be much less than 2pq
Nonrandom mating<span> occurs when the probability that two individuals in a population will mate is not the same for all possible pairs of individuals.
</span>
Natural selection - p and q will stay the same

The interactions between individuals and their environment are what determines whether their genetic information will be passed on or not. The sum of the allele frequencies for all the alleles at the locus must be 1, so p + q = 1.

Small population size - Changes in p and q cannot be predicted

Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error

Gene flow - p will decrease and q will increase

Migrants result change the distribution of genetic<span> diversity within the populations, by modifying the allele frequencies. </span>

A car travelling at 15 m/s comes to rest in a distance of 14 m when the brakes are applied.
stira [4]

Answer:

-8.04 m/s2

Explanation:

To find the answer to this, you have to use the 4th kinematic equation:

v^{2} = v^{2}_{0}  + 2ax

You plug into the equation to get:

0 = 15^{2} + 2a(14)

solve for a to get

-8.04 m/s2

Estimate the volume of a piece of molecular cloud that has the same amount of water as your body.
noname [10]

Question:

The water molecules now in your body were once part of a molecular cloud. Only about onemillionth of the mass of a molecular cloud is in the form of water molecules, and the mass density of such a cloud is roughly 2.0×10−21 g/cm^3.

Estimate the volume of a piece of molecular cloud that has the same amount of water as your body.

Answer:

The volume of cloud that has the same density as the amount of water in our body is 1.4×10²⁵ cm³

Explanation:

Here, we have mass density of cloud  =  2.0×10⁻²¹ g/cm^3

Density = Mass/Volume

Volume = Mass/Density =   If the mass is 40 kg and the body is made up of 70% by mass of water, we have

28 kg water = 28000 g

Therefore the Volume = 28 kg/ 2.0×10⁻²¹ g/cm^3 = 1.4×10¹⁹ m³ = 1.4×10²⁵ cm³.

Therefore, the volume of cloud that has the same density as the amount of water in our body = 1.4×10²⁵ cm³.

A 100-kg running back runs at 5 m/s into a stationary linebacker. It takes 0.5 s for the running back to be completely stopped.
Elza [17]

Answer:

1000 N

Explanation:

First, we need to find the deceleration of the running back, which is given by:

a=\frac{v-u}{t}

where

v = 0 is his final velocity

u = 5 m/s is his initial velocity

t = 0.5 s is the time taken

Substituting, we have

a=\frac{0-5 m/s}{0.5 s}=-10 m/s^2

And now we can calculate the force exerted on the running back, by using Newton's second law:

F=ma=(100 kg)(-10 m/s^2)=-1000 N

so, the magnitude of the force is 1000 N.
