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).
That would be A.
Most antibiotics that are used for gram positive bacteria target the peptidoglycan cell wall, but the ones for gram negative bacteria are more advanced and specific and target the cell membrane and alter the cell’s function(processes of proteins and dna/gene expression).
Answer:
Insulin stimulates the liver to store glucose in the form of glycogen. A large fraction of glucose absorbed from the small intestine is immediately taken up by hepatocytes, which convert it into the storage polymer glycogen. Insulin has several effects in liver which stimulate glycogen synthesis.
Explanation:
We have to find the force of gravity of an object that has a mass of 20 kg and then to choose the correct answer. The formula for the force of gravity is: F = m * g, where m is the mass of an object and g is the acceleration of the gravity ( on Earth : g = 9.81 m/s^2 ). F = 20 kg * 9.81 m/s^2 = 196.2 N, or approximately 196 N. Answer: A. 196 N<span>.</span>
