What knowledge did Darwin’s theory need in order to be tested, which he didn’t have at the time?
A. Adaptations
B. Age of the Earth
C. Living organisms
D. Fossils
Answer:
B. Age of the Earth
Explanation:
The answer can be found on the slide with the heading "Could Darwin Explain Everything?"
Victorian scientists found it difficult to test Darwin's theory. For Darwin's theory to work, the Earth needed to be millions of years old, but it's age was not known at the time.
Therefore, the answer is B. Age of the Earth.

Briefly explain how the volume in your thoracic cavity changes during inhalation and exhalation. Be sure your answer includes how those changes in volume lead to air moving in and out. Include which gas, oxygen or darbon dioxide regulates respiration rate.
Answer:
Both inhalation and exhalation depend on pressure gradients between the lungs and atmosphere, as well as the muscles in the thoracic cavity.
Explanation:
The thoracic cavity, or chest cavity, always has a slight, negative pressure which aids in keeping the airways of the lungs open. During the process of inhalation, the lung volume expands as a result of the contraction of the diaphragm and intercostal muscles (the muscles that are connected to the rib cage), thus expanding the thoracic cavity. Due to this increase in volume, the pressure is decreased, based on the principles of Boyle’s Law. This decrease of pressure in the thoracic cavity relative to the environment makes the cavity pressure less than the atmospheric pressure. This pressure gradient between the atmosphere and the thoracic cavity allows air to rush into the lungs; inhalation occurs. The resulting increase in volume is largely attributed to an increase in alveolar space because the bronchioles and bronchi are stiff structures that do not change in size.During this process, the chest wall expands out and away from the lungs. The lungs are elastic; therefore, when air fills the lungs, the elastic recoil within the tissues of the lung exerts pressure back toward the interior of the lungs. These outward and inward forces compete to inflate and deflate the lung with every breath. Upon exhalation, the lungs recoil to force the air out of the lungs. The intercostal muscles relax, returning the chest wall to its original position. During exhalation, the diaphragm also relaxes, moving higher into the thoracic cavity. This increases the pressure within the thoracic cavity relative to the environment. Air rushes out of the lungs due to the pressure gradient between the thoracic cavity and the atmosphere. This movement of air out of the lungs is classified as a passive event since there are no muscles contracting to expel the air.
explain movement in fern
Answer:
One of the most typical ways that plants like ferns move is through a process known as phototropism. Essentially, they move and grow towards light .Plants may also move or grow in response to other stimuli, in addition to light. They can grow or move in response to physical touch, in response to a chemical, or toward warmth

Why are there craters on the surface of the moon?(1 point)
Craters formed when acidic water dissolved the surface of the moon.
Craters developed from deep waterspouts in oceans on the moon.
Craters were created when sinkholes formed after rainstorms on the moon.
Craters resulted when meteoroids crashed into the surface of the moon.
Answer:
Craters resulted when meteoroids crashed into the surface of the moon.
Explanation:
Craters resulted when meteoroids crashed into the surface of the moon. The correct option is D.
What are carters?On many solid planets and moons, craters are the most common surface features.
Craters cover both Mercury and the Moon. Numerous circular holes cover this area of the Moon. Each of these craters was formed when an asteroid or comet collided with the Moon's surface.
A crater is a bowl-shaped depression or hollowed-out area caused by a meteorite impact, volcanic activity, or an explosion. Impact craters are craters formed by a meteorite colliding with the Earth.
Scientists can study a planet's history using impact craters even when the records are buried beneath the surface.
Buried material is ejected during impact, while outward pressure pushes the rock at the crater's edge upward, forming a rim.
Thus, the correct option is D.

Describe the general temperature of ocean currents near the equator and the poles.
Answer:
Currents flowing away from the Equator are generally warm.
Explanation:
That is because the Equatorial regions is the source of warm air and water. Ocean currents flowing from the Equator thus carry this warm water with them. The most prominent example is the Gulf Stream in the Atlantic Ocean, which runs most of the way to the North Pole and brings mild winter climates in its wake to adjacent coastal areas. In the Pacific Ocean the Alaska Current likewise carries warm water northward making Anchorage, Alaska much milder in winter than inland areas with the same latitude.

Assume that a 100 base pair DNA ladder contains 45 cytosines. How many guanines are there?
Answer:
45 guanines
Explanation:
In a DNA strand, each nitrogen base only pairs with one other specific base.
Adenine pairs with thymine, and cytosine pairs with guanine.
This means that the amount of adenine is always equal to the amount of thymine, and the amount of cytosine is always equal to the amount of guanine.
So, if the DNA ladder has 45 cytosines, there will be 45 guanines.

Which of the following is a result of two continental crusts buckling and cracking? *
The result of two continental crusts buckling and cracking is San Andres Fault.
The San Andrés fault is a geological fault that is about 1,300 km long. This fault is located in the western part of the United States, specifically in the state of California, and reaches a part of Mexico.
The San Andrés fault arose as a result of the tectonic encounter between the North American Plate and the Pacific plate and their relative horizontal displacement.
A characteristic aspect of this fault is the great crack and buckle that is produced through a long territory. In addition, the earthquakes of 1857, 1906, 1989, 1940, among others.
According to the above, the correct answer is option D because it mentions the correct geological event, while the other options mention phenomena that are not related to the meeting of two continental plates.

Why does the pectoral girdle need to be flexible while the pelvic girdle needs to be rigid?
Answer:
Flexibility: pectoral girdle is more flexible-less ligaments, ball and socket joint is shallower
Security: pelvic girdle is more secure, deeper socket. there are more dislocated shoulders than dislocated hips
ability to bear weight: pelvic girdle can bear more weight-the pelvic girdle has bones that are fused (os coxa) and a joint with the sacrum. the pectoral girdle has a little bone called the clavicle connecting it to the body wall.
Explanation:
The pelvic gridle is rigid to protect internal organs and support body weight whereas pectoral gridle require to provide movement to upper limbs.
The girdles are part of the appendicular skeleton which is attached to upper limbs and lower limbs, The upper limbs attach to pectoral gridles and lower limbs attached to pelvic gridles.
1. The pectoral gridle:
connects your upper limbs to the bones along the axis of your body.The pectoral girdle has two bones clavicle, or collarbone and scapula, or shoulder blade.it has ball and socket joint that provide movement to the upper limb.2. The pelvic gridle:
