Which of the following best describes how an observation of the fossil record supports the theory of evolution?
OPTIONS
Hard parts of animals, such as bone and teeth, are much more likely to become fossilized than other parts made of soft tissue.
The fossils found in rock layers of different ages are related to, but different from, fossils found in rock layers above and below.
The fossil record has many more examples of organisms that lived in water where their remains were more likely to be buried quickly.
Close examination of fossils can reveal details and the diet, environment, and even behaviors of the organisms the fossils represent.
Answer:
The fossils found in rock layers of different ages are related to, but different from, fossils found in rock layers above and below.
Explanation:
This answer gives the best answer. Remember: simple life forms gradually evolved into more complex ones.

Explain how oxygen moves into and out of the structures shown below
Explanation:
In a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls. ... From the heart, this blood is pumped to the lungs, where carbon dioxide passes into the alveoli to be exhaled.The process that is shown in the structure is called diffusion. The structure shows the movement of oxygen from the alveoli to the blood.
What is diffusion?Diffusion is a process of movement of a substance from a higher concentration to a lower concentration region. This movement is according to the concentration gradient. This process doesn't need any energy because of the movement according to the concentration gradient.
The capillaries (small blood vessels) lining the alveolar walls allow oxygen to diffuse from the alveoli to the blood throughout this process. This blood is pushed from the heart to the lungs, where carbon dioxide enters the alveoli and is expelled.
Thus, the process is diffusion, in which the oxygen moves from a higher concentration to a lower concentration.

The correct answer is, An athlete wants to refill an old punching bag used for training. When refilled, the bag will rip if it is kicked with too much force.
What is Force?
Push or pull of an object is called a force.Push and pull come from the objects interacting with one another.Terms like stretch and squeeze can also be used to denote force.Force is an external agent, changing the state of motion of a particular body. It has a magnitude and a direction. The direction towards which the force is applied is known as the direction of the force and the application of force is the point where force is applied.

Read the excerpt from The Mother of America:
Martha Washington's promotion of democratic values as America's original first lady also proved her worthy of the name "Mother of America." She realized that the way she treated the role of first lady would set precedents for future women. Martha had to figure out how to create an atmosphere that reflected democracy and commanded respect from the rest of the world. To accomplish this, she held a reception once a week where different people could enjoy refreshments and exchange ideas. Unlike other events, Martha's reception was representative of democracy, as it was open to different groups of people, including both men and women. Overwhelming respect for Martha led to others calling her "Lady Washington." Despite praise for her work, Martha disliked the restrictions put on her as the first lady and missed her son. In spite of these concerns, Martha did her duty and remained to support the president and her country. Her role in defining America's first lady—the figurative "Mother of America"—was invaluable.

Explanation:
Claim: How does plants reproduce?
Evidence: They reproduce by their structures.
Reasoning: The structures of a plant work together so they have the ability to reproduce. The roots absorb the nutrients. The stew helps to keep the tree or plant straight so it don't fall. And the branches are used to transport the water and nutrients into all the parts of the plant.

The moon starts as a new moon and the steps are:
1. Waning Crescent (The thin light of the moon on the right side)
2. First Quarter (The right half of the moon is lit up)
3. Waxing Gibbous (Most of the right side is illuminated with light)
4. -Full Moon- (The moon is fully lit up with light)
And from here, the steps reverse, Hence it is B
H is the new moon
A is the Waning Crescent
E is the First Quarter
G is the Waxing Gibbous
B is obviously the full moon
And the rest is reversed.

Help muh please I will give Brainliest
Answer:
Earth is not heated in a uniform manner, there are hit and cold spots, e.g you have a desert inland the Sun heats it, hot air rises. Since there can't be a vacuum, colder air from the surroundings must fill the gap, then you get convection.
Explanation:
Explanation:
the answer is B. Convection currents drive atmospheric circulation at the global scale. The Earth is heated most intensely near the equator, where this air rises as part of the intertropical convergence zone. It then reaches high altitudes and diverges poleward as part of the Hadley cell, a permanent circulation cell in the tropics. This is the primary means in which excess energy is transported poleward via the atmosphere. This air and its energy tends to subside in the subtropics, and eventually move poleward again in the Ferrel cell of the mid-latitudes and polar cell of the polar regions through eddy diffusion.
What is this question asking plss explain
Its asking you to identify the relation between the planets mass, number of moons, and the planets distance from the sun. And it wants you to answer in a complete sentence.
For example,
> Mercury has a small mass and is very close to the sun, so it doesn't have any moons.
> Jupiter has a much larger mass than earth and is a lot farther away from the sun, so it has a lot more moons
> Mars has only 1/10th of the mass of Earth, and is only a little farther away from the sun, despite this, it has 2 moons, making it the exception
