DNA replication<span> is </span>semi-conservative<span> because each helix that is created contains one strand from the helix from which it was copied. </span>
<u>Answer:</u>
<em>Polymers of amino acids can be both fibrous as well as globular protein. Hemoglobin is a globular but the collagen is the fibrous protein both being the amino acids.</em>
<u>Explanation:</u>
- <em>Soluble in water: </em>globular protein is soluble in water.
- <em>intermediate filaments:</em> fibrous protein
- <em>Insoluble in water:</em> fibrous protein is insoluble in water.
- <em>function as structural proteins in the cell:</em> fibrous protein.
- <em>some function as enzymes: </em>globular protein.
- <em>structure is somewhat spherical;</em> globular protein.
- <em>structure is rod-like:</em> fibrous protein
Answer: B. Rough strained and heat killed smooth strain kills mouse
Explanation:
Ok, particle is not a very nice word, no real sense of size associated with it
it can be a group of molecules like a speck of sand
referring to the molecules themselves
or refering to the atoms that make up the molecule
now in terms of phase change,
if we consider a speck- a group of molecules- then solids will expand when heated, however this definition falls flat in terms of phase change
ok, how about molecules, as molecules undergo phase change, the molecules in relation to each other will move apart from one another. Solid- molecules are bonded, Liquids- molecules are close and flow around each other, Gas- molecules are a significant distance from one another. But the increase in size when you heat up a molecule, i would have to say yes. adding heat increases energy which increases molecular vibration which would probably increase the overall average size to some unnoticeable degree.
now standalone atoms are just atoms, if you want to consider the electron cloud as size, then heating it up would negligibly cause the outer move outward. but it really depends on the scale of the question
