# The buoyant force acts in all directions.Please select the best answer from the choices providedTF

the first option is correct (true).

the greater the surface area of an object the greater the buoyant force.

This is false so option 2 (F)

Explanation:

On edge 2021 it even says false.

Pink eye is a recessive trait found in deer mice. In a cross between two individuals, both of whom are heterozygous for the pink eye mutation, the following offspring are obtained:Normal 18

Pink eye 2

Use the chi-square test to determine if the observed numbers of offspring fit the expected numbers of offspring from this cross. The value of is: ____________

Explanation:

If pink eye is recessive, it means that the normal eye is the dominant trait. According to Mendelian law, the ratio of normal to pink eye in a cross involving two heterozygous mice should be 3:1.

Chi-square = where O = observed frequency and E = expected frequency.

Phenotype      Observed            Expected          Chi-square

Normal                 18                3/4 x 20 = 15           = 0.6

Pink                       2                  1/4 x 20 = 5           = 1.8

Total Chi-square = 0.6 + 1.8 = 2.4

Degree of freedom = 2 - 1 = 1

Critical Chi-square value at 95% = 3.841

The critical Chi-square value is more than the calculated value. Hence, the observed number of offspring fits the expected number of offspring.

What makes ribosomal RNA useful as a molecular clock? (2 points) A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations. Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other. A slow mutation rate makes it useful for determining evolutionary relationships between ancient species. It is only found in select organisms, making it easier to compare relationships between species that have it.

The correct statement is that a slow mutation rate makes it useful for determining evolutionary relationships between ancient species.

Explanation:

The rRNA or ribosomal RNA has an application as a molecular clock because of many factors. It exhibits a very slow mutation rate, that is, around one million years because of which it stays highly conserved in all the organisms. In the ribosomal RNAs of two organisms, the degree of mutations can be associated directly with the time they were originated in the past.

In supplementation, it possesses essential biological function because of which it can be witnessed in almost all the species.

Based on the information given, a pandemic simply means the spread of an infectiousdisease.

### What is HIV?

It should be noted that the difference between an epidemic and a pandemic is the degree if its spread.

HIV is simply a virus that attacks the immune system. It can be gotten through unprotected intercourse, sharing sharp objects, etc. It should be noted that in the long run, HIV leads to AIDS.

It should be noted that HIV is most prevalent in Sub Saharan Africa. There are presently no cure for HIV but there are medications to control the complications.

The average life expectancy for someone with HIV is 56 years.
