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).

Nookie1986 [14]

It will have no effect because the order in which ingredients are mixed will not change the fact that matter cannot be created nor destroyed.

<h3>Effect occurs on mass</h3>

The order in which we add the ingredients do not affect the mass of the batter because the order in which ingredients are mixed will not change the fact that matter cannot be created nor destroyed.

The mass of the batter remains the same due to the incorporation of same quantity of ingredients so we can conclude that option A is the right answer for this question.

What would be the anti codon in the tRNA for the amino acid trp (tryophan)?
MrRissso [65]
How do the genes in our DNA influence our characteristics? For example, how can a gene determine whether a person is an albino with very pale skin and hair? Basically, a gene is a segment of DNA that provides the instructions for making a protein, and proteins influence our characteristics. This chart describes how two different versions of a gene result in two different versions of a protein which in turn can result in either normal skin and hair color or albinism. DNA  Protein  Characteristic   Version of the gene that provides instructions to make normal protein enzyme  Normal enzyme that makes the pigment molecule in skin and hair  Normal skin and hair color Version of the gene that provides instructions to make defective enzyme  Defective enzyme that does not make this pigment molecule  Albinism (very pale skin and hair) A gene directs the synthesis of a protein by a two-step process. The first step is transcription of the gene in the DNA. Transcription produces a messenger RNA (mRNA) molecule. The second step is translation of the mRNA molecule. Translation produces a protein molecule. During transcription, the sequence of nucleotides in a gene in the DNA is copied to a corresponding sequence of nucleotides in mRNA. During translation, the sequence of nucleotides in the mRNA determines the sequence of amino acids in the protein. After translation, the sequence of amino acids in the protein determines the structure and function of the protein. Differences in protein function can influence characteristics such as normal skin and hair color vs. albinism.

What is the boundary between the earths lower mantle and the upper mantle called ?
Alenkasestr [34]

Answer:

i have trusted my best to answer

Explanation:

Edit

The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.
