Geologists believe that during the last ice age, glaciers advanced and retreated worldwide, resulting in changes in sea levels and climate. So, the correct option is B.
Who are Geologists?Geologists are scientists who study the Earth, its composition, structure, processes, and history.
During the last ice age, which lasted from about 115,000 to 11,700 years ago, Earth's climate was much colder than it is today. Geologists believe that a variety of factors contributed to the ice age, including changes in Earth's orbit, atmospheric composition, and plate tectonics.
One major feature of the last ice age was the formation of massive ice sheets and glaciers, which covered much of the Northern Hemisphere. These ice sheets were up to 3 miles thick and covered Canada, Greenland, and parts of the northern United States and Europe. As a result, sea levels dropped by as much as 300 feet, exposing land bridges between continents and allowing humans and animals to migrate across them.
Another feature of the last ice age was the occurrence of periodic "ice ages within an ice age" known as stadials. During these stadials, temperatures in some regions of the world dropped by as much as 20 degrees Celsius, leading to widespread glaciation, droughts, and other environmental changes.
Overall, the last ice age was a complex and multifaceted period in Earth's history, and scientists continue to study it to better understand the mechanisms that drive climate change on our planet.

When outer objects are observed from inside water, they appear at more distance, why?
Answer:
An object seen in the water will usually appear to be at a different depth than it actually is, due to the refraction of light rays as they travel from the water into the air. ... If the angle of the beam is increased even farther, the light will refract with increasing proportion to the entry angle.

To inherit an autosomal recessive disorder requires a person to receive the disease-causing allele from:.
Autosomal recessive inheritance is a form a genetic factors can be given down from parent to child. A genetic condition can occur when the child inherits one copy of a changed gene from each parent. The parents of a child with an autosomal recessive condition usually do not have the disease.
How is an autosomal recessive disorder inherited?In an autosomal recessive disorder, one mutated gene is inherited from each parent.
The parents each carry one mutated gene and one normal gene for the condition, although the parents do not have the condition.
Thus, Autosomal recessive inheritance is a way a genetic factors can be passed down from parent to child.

What are the two kinds of pyrimidines found in dna?.
Answer:
DNA are cytosine and thymine
Explanation:
in RNA, they are cytosine and uracil. Purines are larger than pyrimidines because they've a two-ring shape whilst pyrimidines simplest have a unmarried ring.
Answer:
Cytosine and Thymine
Explanation:
Of the four DNA bases, (C, T, A and G), C and T are pyrimidines. The way I remember it is, C, U (which is only in RNA) and T are "pyrimidines", which has more than 3 syllables, hence there are 3 bases in this category, as compared to purines which only contain 2 (A and G). Hope that helps and it's not confusing

Here’s a specious argument: "According to the simulation, the average temperature of the Earth with the maximum concentration of greenhouse gases is only 10 degrees Fahrenheit warmer than it is today. That’s nothing to worry about. " Explain one thing wrong with this statement
The statement used the word 'average' in relation to the whole globe. This means that some parts of the earth will experience more warming than others.
Averages and variationsAn average is obtained by summing up all the variates in a data set and dividing it by the total number of variates. Thus, a single figure is used to represent the entire data set.
The problem here is that the variations within the data set are hidden with averages.
Using average to represent an increase in the temperature of the earth as a result of increased concentration of greenhouse gases can be dangerous. This is because some parts of the world will experience far larger temperature changes while others will experience lower than the average.

Explanation:
Deoxygenated blood from different organs comes to the right atrium through the vena cava.
From the right atrium, blood goes to the right ventricle. The tricuspid valve between the right atrium and right ventricle prevents the backflow of blood.
From the right ventricle, blood goes to the lungs through the pulmonary artery.
Inside the lungs, carbon dioxide is removed from the blood and oxygen enters the blood.
