PLEASE HELP BIOLOGY!! WILL GIVE BRAIN!!

Answer:

The Earth was formed about 4.5 billion years ago—that's a very long time ago! It's hard to say exactly what the Earth's daily weather was like in any particular place on any particular day thousands or millions of years ago. But we know a lot about what the Earth's climate was like way back then because of clues that remain in rocks, ice, trees, corals, and fossils.

These clues tell us that the Earth's climate has changed many times before. There have been times when most of the planet was covered in ice, and there have also been much warmer periods. Over at least the last 650,000 years, temperatures and carbon dioxide levels in the atmosphere have increased and decreased in a cyclical pattern.

These two clue show how the amount of carbon dioxide and the Earth's temperature have changed over the last 650,000 years. Both clue show a similar up-and-down pattern.

People didn't cause the climate change that occurred thousands or millions of years ago, so it must have happened for other natural reasons.

Answer:

The correct answer is - acidic and basic

Explanation:

Answer:

A mechanical wave is created by putting energy into it. ... Surface waves run along the border between two materials; transverse waves are waves in which the vibration is at 90 degrees to the direction of motion; and longitudinal waves occur when the vibration is parallel to the direction of motion.

Answer:

water

Explanation:

Answer:

1. The core is made almost entirely of metal specifically, iron and nickel.

2. The structure of the inner core iron and nickel.

3.Earth's outer core is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle.

4.In terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. There's also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides.

5.The asthenosphere is now thought to play a critical role in the movement of plates across the face of Earth's surface.

Answer:

Birds descended from the most recent common ancestor of reptiles. Scientists recently revised the classification of the red panda (Ailurus fulgens).

Explanation:

Global energy demand is increasing due to industrial activity and advances in both developing and developed countries. ... The GHGs from geothermal energy systems for electrical power production and space heating applications are much lower than those from conventional fossil fuel energy systems [3,4].

Answer:

Explanation:

The demand for energy across the world is constantly rising. This increased demand is caused in part by the increase in population, and by economic development. It is because these areas experienced large-scale economic development, their original energy sources were fossil fuels – first coal and  oil and gas.

Answer:

The answer is b

Explanation:

The lymphatic system doesn't coagulate the blood it moves it around the body to keep it stagnate.

Hope this helps!

Answer:

This would be an example of technology.

Explanation:

Artificial limbs, or prostheses, are used to replace a missing body part which may have been lost due to trauma, disease or congenital defect. The type of prosthesis a person can use is dependent on the individual, including the cause of amputation or limb loss, and the location of the missing extremity. These come in all shapes and sizes, for whatever you need.

Have a nice day!

Answer:

A technology, since the actual prosthesis is a human creation that solves a problem. Science is nothing physical. It is the combination of laws and theories that explain our universe and helps us make decisions. We don't really invent science, we describe it.

Science is ideas. Technology is human creations.

Science generally underpins all new technology.

In your human leg prosthesis example science is crucial in choosing (or developing) suitable materials for construction of the prosthesis. The material must be relatively stable, not break down into toxic substances and have good durability. Knowledge of human Biology is also important if you want to start replacing human body parts.

Basically chemistry and biology are important in the prosthesis development. There is also probably physics regarding tensile strength requirements.

The actual end result of the human prosthesis is a technology which solves a problem of degraded human parts.

So to reiterate, it is a technology.

Answer:

The correct answer is - Commensalism

Explanation:

Commensalism is a symbiont relationship in which there is a relationship between two organisms in which one gets benefits and the other organism is unaffected.

Human skin has many commensal bacteria that fed on dead cells of the skin. Here humans are hosts that do not get harm and bacteria rely on them for survival.

Explanation:

Viruses don't have cell walls that can be attacked by antibiotics; instead they are surrounded by a protective protein coat. Unlike bacteria, which attack your body's cells from the outside, viruses actually move into, live in and make copies of themselves in your body's cells.

Answer:

The spinal cord is made up of bundles of nerve fibers. It runs down from the brain through a canal in the center of the bones of the spine. These bones protect the spinal cord. Like the brain, the spinal cord is covered by the meninges and cushioned by cerebrovascular fluid.

Answer:

A. A computer

Explanation:

The way your nervous system works can be compared to how your computer works. When you press the power on your computer, a signal goes out. The signal is a catalyst that generates a number of actions and responses. An electric current travels over the wires maintaining a connection to electricity

The nervous system may be compared to a computer. So, the correct option is A.

The nervous system is defined as a highly complex part of an animal that coordinates its functions and sensory information through the transmitting signals from different parts of its body. This system includes

1. The central nervous system consists of the brain and spinal cord)

2. The peripheral nervous system consists of the nerves that extend from the spinal cord to the rest of the body

3. Other nerve tissue.

The nervous system may be compared to a computer.  The way our nervous system works can be compared to the way your computer works. When we press power on computer a signal comes out like CNS and PNS work in the body

So, the correct option is A.

Answer:

Fertilization

Explanation:

Fertilization is the joining of gametes (egg and sperm) to form a zygote.

Based on this information, this technique is an example of selective breeding, which is a reproduction control and management technique.

It implies a manipulation of the characteristics that are inherited, that is, it is a technique that consists of choosing the phenotypes of the organisms that are cultivated or bred.

This peculiarity allows guiding the evolution of the species according to the needs of the human being to have specimens with the desired characteristics in a stable manner.

Therefore, we can conclude that based on this information, this technique is an example of selective breeding, which is a reproduction control and management technique.

Answer:

function as the powerhouse of cell

Explanation:

we have read the power house of cell as a mitochondria

==========================================================

Explanation:

The mitochondria is responsible for generating the cell's energy, hence the phrasing "the mitochondria is the powerhouse of the cell".

The nucleus holds the DNA, so we can rule out choice B. The DNA in turn is connected to forming the proteins. The actual protein synthesis happens in the ribosomes, but the DNA is used as a blueprint (more or less) to assemble the correct amino acids in the correct order to form the complicated protein chains. In short, the nucleus indirectly helps direct the protein synthesis, so we can rule out choice A.
