Answer: d. Extracellular matrix was discovered more than 20 years ago.

Explanation:

According to biological sciences, the extracellular matrix is a matrix that consists of three dimensional network of extracellular macromolecules such as enzymes, collagen and glycoproteins which provide structural and biological support for surrounding cells as well.

It is found that it is discovered over 20 years ago in the matrix formed in the mouse EHS sarcoma. Therefore, correct answer is (d).

The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence

Explanation:

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.

Because current instruments don't allow astronomers to peer back at the universe's birth, much of what we understand about the Big Bang Theory comes from mathematical formulas and models. Astronomers can, however, see the "echo" of the expansion through a phenomenon known as the cosmic microwave background.

The phrase "Big Bang Theory" has been popular among astrophysicists for decades, but it hit the mainstream in 2007 when a comedy show with the same name premiered on CBS. The show follows the home and academic life of several researchers

What does the graph tell us about the humidity in any given location on Earth?
Veseljchak [2.6K]
The best answer would be, 'The warmer the air temperature, the greater the humidity.'

The second choice is true, but the graph is representing humidity, not precipitation. That is off-topic.

C could also be true, but the chart didn't refer to any body of water.

I hope this helped you!

Brainliest answer is always appreciated!

Which kind of organism does not generally require oxygen or sunlight to live?
gregori [183]
Answer is A.

Archaea requires neither sunlight for photosynthesis as do plants, nor oxygen. Archaea absorbs CO2, N2, or H2S and gives off methane gas as a waste product the same way humans breathe in oxygen and breathe out carbon dioxide. An example is chemosynthetic bacteria by sea drifts. They use chemical energy to produce vital processes to live.
