D. Mixed with tin to make it stronger
Explanation:
When copper (Cu) combined with Tin(Sn) they make bronze. The product which these two elements form when combined with each other is called "Alloy" which is the Bronze that was mentioned in the question.
Why is this done?
This is done to produce an "Alloy" and alloy is usually used because it is stronger.
Industries prefer alloy in situation where they need strongness that they cannot find in a single element.
I took the test on Plato and got it correct. The answer is engineers.
Explanation:
Gravitational potential energy = mgh, where m is the mass of the mountain climber, g is the gravitational force and h is the height from the base.
Since m and g are constants, the climber's potential energy will be the lowest when he's at the end of the climb, at the base of the mountain. (B)
Answer:
b., d., e. and f. are correct
Explanation:
It is likely that the lack of nine amino acids in the C-terminus or the N-terminus of the cyclin protein affects its function. In general, these protein regions undergo post-translational modifications (such as phosphorylation or ubiquitination) that act as control points in signaling pathways
