AlekseyPX

The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.

Explanation:

Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".

What percent of the sunlight is actually converted into chemical energy via photosynthesis?

kirill115 [55]

Photosynthesis is a process in which green plants and few organisms use sunlight to synthesize their food from carbon di- oxide and water. In plants, during photosynthesis, green pigment known as chlorophyll is involved and oxygen is generated at a by product.

All the sunlight falling on plant is not absorbed. Only half of the falling light which lies in the right frequency to power photosynthesis is absorbed. Out of this falling light, only 8 % to 11% is absorbed by the plant and only 3 % to 6 % is actually used to form chemical energy.

What are the consequences of overdrawal of water?

Klio2033 [76]

Answer:

As the water table goes low, water may not be easily obtained leading to it scarcity. Overdrawal of water can also lead to sinking or lowering of the land surface that can make it prone to flooding. Streams and water bodies may also get disconnected due to over-withdrawal of water.

A locus that affects susceptibility to a degenerative brain disease has two alleles, V and v. In a population, 16 people have ge

Pie

Answer:

Yes, the population is evolving

Explanation:

Hardy-Weinberg equilibrium states that a population is not evolving if it is in hardy weinberg equilibrium as the alleles frequency do not change over time in generations.

In mathematical equation, the genotype frequency will be -P²+2Pq+q²=1 and allele frequency will be p+q=1, where p = dominant allele and q will be recessive allele.

In the question, since the observed genotype are-

P² - VV= 16

2Pq- Vv- 92

q²- vv- 12

1. Calculate allele frequency

Now we will calculate if the expected value is same or close or not.

We will calculate allele frequency

Population has 120 individuals which means it has - 240 alleles.

In which V (p) will be- 32 +92= 124 allele

p- dominant allele/ total allele= 124/ 240 = 0.52

P= 0.52

q will be 1-0.52= 0.48

2. Expected genotype frequency

Now we will calculate expected genotypic frequency.

P²- 0.52 X 0.52= 0.27

2Pq = 2 x 0.52x 0.48 = 0.5

q²= 0.48 x 0.48 = 0.23

3. Expected progeny

P²= 0.27 x 120= 32 VV

2Pq= 0.5 X 120= 60 Vv

q²= 0.23 x 120= 28 vv

Since the observed value is not equal to the expected value therefore the population is not in Hardy- Weinberg equilibrium and the population is evolving.

Thus, Yes, the population is evolving is correct.
