Answer 1

Answer:

The correct answer is - A. through the use of earthquake waves.

Explanation:

The interior of the earth can not be studied or seen by digging the hole, for that scientist normally use the movement of seismic waves, from earthquakes or nuclear test explosions, are reflected, slow down, sped up bent by passing through the different layers.

Waves behave differently as they move in different layers and their material helps scientists to learn and study the layers and their constituents. It explains that the Earth's interior has a series of concentric shells, with a thin outer crust, a mantle, a liquid outer core, and a solid inner core.

You are a mad scientist. You have figured out a way to replace one part of the respiratory and circulatory systems. You believe by doing this one thing you can create an army of physically unbeatable warriors and conquer the world. (Remember you are MAD!) a - What part would you replace to accomplish this? b - What would you replace it with? c - Explain your thinking on how doing this would help create these powerful warriors.

Answers

Answer:

I'd proceed to order pipes from ebay as to replace said parts.

During the process I'd question why is there an army of beef-cake Mega-Men in my basement.

Since I'm a mad scientist I'd make some type of body armor that enhances durability, Thus allowing my warriors to remain standing tall while taking a few rounds of a some good ol' bullet lead.

I would also use BIO-Tech enhancing their skin durability to take the deepest of cuts. Muscle definition and power so my men could slap an Elephant to next week.

9. why Energy released by aerobic and anaerobic respiration in animal are not same.​

Answers

Answer: Anaerobic respiration produces a relatively lesser amount of energy as compared to aerobic respiration, as glucose is not completely broken down in the absence of oxygen. In animal cells anaerobic respiration often occurs during exercise. The glucose does not get fully broken down in this process, so it does not release its full potential energy. Instead of carbon dioxide and water it breaks down to form lactic acid and a small amount of energy.

A panda (herbivore) eats bamboo shoots and leaves, while a lion (carnivore) preys on other animals.A bear (omnivore) eats both plants and animals, while a vulture (scavenger) feeds on the remains of dead animals.What are consumers?

In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.

Consumers can be classified into several categories based on what they eat. For example:

Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.

Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.

Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.

Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.

Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

It could grow at such an extrem erate that it could use up all natural resources that the native species needs to survive. thus breeding out all native species and becoming a invasive species.

Which statement about how geologists study the ages of rock layers is true?
The law of superposition means that older rocks are on top.
Geologists can find the exact age of a rock by looking at its relative position.
The principle of original horizontality provides the basis for the law of superposition.
Relative age can be determined by using the concept of unconformity.

Answers

Answer: The principle of original horizontality provides the basis for the law of superposition.

Explanation:

The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.
