Yes, a tree is falling over in a forest make a sound because both the tree and ground are hard surfaces which can produces sound by contact physically with each other. For testing this hypothesis, we have to take a tree and cut that tree. when the tree falls on the ground it will definitely produces sounds by contact physically with the ground when falls with a large force.

The tree population and the ground population of ticks cannot mate and have offspring indicates speciation has occurred.
What is population?"A population is defined as a group of individuals of the same species living and interbreeding within a given area."What is speciation?"Speciation is the evolutionary process by which populations evolve to become distinct species."The ticks of tree and ground population evolve without interfering with one other. Forms a different species and no mating occurs between them.Hence, the correct answer is: The tree population and the ground population of ticks cannot mate and have offspring.

Why are seismic waves considered
mechanical waves?
A. They must travel through a medium, such as
the bedrock of the Earth.
B. They will only travel through empty space.
C. They travel in circles.
D. They do not require a medium.
Answer:
The correct answer is - option A.
Explanation:
The seismic waves are the waves that are the result of an explosion or the breaking of the rock within the earth. In other words, when these explosions or breaking cause an energy transfer within the earth are seismic waves. Seismic waves require a medium to travel and normally it is the earth.
The bedrock of earth is a great example of a medium for traveling these waves that make it a mechanical wave. Earthquake is the result of such waves.

what does primary succession mean
A ray of light is passing through a medium making an angle of 45°. If the
refractive index of the medium is 1.4, calculate the angle of refraction. [Ans: 30°)
Answer: By Snell's law, we can see that the angle of refraction is 30.34°
Explanation:
Snell's law says that:
If a ray in a medium of refractive index n₁, insides with an angle θ₁ in another medium with refractive index n₂, then the angle of refraction θ₂ is given by:
n₁*sin(θ₁) = n₂*sin(θ₂)
We know that:
The incidence angle is 45°, then: θ₁ = 45°
We can assume that the first medium is air, then n₁ = 1
The refractive index of the other medium is 1.4, then n₂ = 1.4
Replacing these in the Snell's law equation we get:
1*sin(45°) = 1.4*sin(θ₂)
Now we can solve this for the angle of refraction:
sin(45°)/1.4 = sin(θ₂)
Asin(sin(45°)/1.4 ) = Asin( sin(θ₂)) = θ₂ = 30.34°
So the angle of refraction is 30.34°

If two brown eyed people had a blue eyed child, what is the genotype of the parents?
Answer:the blue eyes people in the family long before them could have skipped generations
Explanation:
Answer:
Because the two genes depend on each other, it is possible for someone to actually be a carrier of a dominant trait like brown eyes. And if two blue eyed parents are carriers, then they can have a brown eyed child.

You are a wild rabbit and your species currently lives in desert. Most of the rabbits are brown but there are a few that are white. An asteroid hits the Earth and the environment you live in suddenly becomes very cold. It begins to snow leaving snow covering the ground. Will your species be able to adapt and line in the new environment? Explain and give details (what happens to white rabbits and brown rabbits.)
I need the brainylest answer and I will give a brainylest answer for this.
Answer:
The species of wild rabbits that are brown would most likely have a harder time adapting than the white rabbits to the new environment.
Explanation: The brown rabbits are going to have a hard time living in the snow mostly because of their color. The brown rabbit is more likely to be able to live in the desert because they can camouflauge with their surroundings (the sand). Therefore, camouflaging in the white snow to escape a predator would be impossible for brown rabbits, since they could easily be spotted. Furthermore, the white rabbits would have a higher chance of survival since they can camouflage easier in the snow.
If a mosquito cell has 3 chromosomes, is it haploid or diploid?
Answer:
If an orangutan cell had 24 chromosomes, then the cell is diploid or haploid (circle one). If a mosquito cell had 3 chromosomes, then it would be a gamete or a somatic cell (circle one).

All mosquitoes have six diploid chromosomes (2N = 6), and their chromosomes are either submetacentric or metacentric, mosquito cell has 3 chromosomes and is haploid.
What is the difference between haploid and diploid?Three pairs of chromosomes make up the Anopheles mosquito's chromosomal complement: two sex chromosomes As a consequence, when a sperm and egg cell join during fertilization, the resultant zygote has 46 chromosomes.
The number of chromosomes and their shape in mosquitoes are extremely similar mosquito cell has 3 chromosomes, and are haploid.
Therefore, to go from haploid to diploid cells, we only need to double the number of chromosomes. This quantity is denoted by the abbreviation 2n, where n is the number of chromosomes.

Cancer is caused by abnormal growth is due to a genetic mutation. Which of the following can cause this genetic mutation? (Choose all that apply)
•Can be inherited
•Acquired with age after many rounds of cell division
•Caused by exposure to radiation
•Acquired from contact with a person who has cancer
Answer: Can be inherited, acquired with age after many rounds of cell division, caused by exposure to radiation
⬇ Explanation(s): ⬇
Exposure to Radiation: Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.
Cell Division: Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Cancer is the abnormal growth of the cells and can be due to genetic mutation. These mutations can be caused by inheritance, exposure to radiation, and age. Thus, options a, b, and c are correct.
What is the cause of cancer?Cancer is a disease where the cells have lost the ability to stop cell division resulting in the accumulation and uncontrolled growth leading to tumors. Cancers are caused by genetic mutations.
The mutations can be inherited if they are in the germinal cells and can be passed to the offspring. The radiations like exposure to UV can alter the DNA sequence as they are mutagens.
It can also be caused due to the increase in age as the cell division is affected by age and the mechanism may fail or mutate resulting in uncontrolled cell growth.
Therefore, options a. inheritance, b. acquired with age, and c. exposure to radiation is the cause of genetic mutation.

The scientists notice that one measurement stands out.
How should the scientists best deal with this
measurement?
O accept it as true and use 85 micrometers in the data
when they find the average length
O accept it as true but say that it is the only cell that has
ever been that long
O consider that there was an error during measuring
and collect further data
O consider that it is possible but very unlikely for these
bacterial cells to be so long
Answer:
consider that there was an error during measuring
and collect further data
Explanation:
Human errors during observation are common, and although they should keep their minds open to the probability of it being longer, it is much more likely the researcher made a mistake, which they need to account for first.

Which best describe the structure of DNA?
Answer:
DNA structure
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
Explanation:
Bobcats are generally solitary and establish territories of a certain size where they hunt for food. What type of population dispersion would you expect bobcats to have?
Answer:
Uniform dispersion.
Explanation:
The bobcats' population distribution would be a uniform dispersion because they are distributed in an area in a balanced way. That is to say, that there is space between them and that each bobcat establishes its personal space when hunting and for their daily life. As they are solitary animals, they do not live in groups and only associate with other bobcats to reproduce themselves.
