In the Linnaean system, birds and reptiles are each classified in a separate class. However, in the modern system, birds are members of the clade Reptilia. Which conclusion, based on evidence, did scientists cite to revise the classification of birds
Answer:
Birds descended from the most recent common ancestor of reptiles. Scientists recently revised the classification of the red panda (Ailurus fulgens).
What is NOT a function of the
nucleus?
A. Directs protein synthesis
B. Houses DNA
C. Functions as the powerhouse of the cell
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.

: Is a human leg prosthetic an example of science or technology? Explain your answer.
QUICK!!!! ANSWER PLEASE WITH EXPLANATION TOO!!!
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.

11. Describe how the climate most likely changed between 220 million and 12 thousand years ago
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.
Why has the demand to find more than fossil fuels for energy increased?
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.
