Answer:
The amount of energy stored in a molecule of ATP compared to the amount stored in a molecule of glucose is <u>less</u>.
Explanation:
Both ATP and glucose are energy containing molecules. However, a molecule of glucose has about 90 times more energy than a molecule of ATP.
But, ATP is used by most cells as the quickest source of energy. This is because ATP can easily be broken down to generate energy and it transfers energy very effectively.
A molecule of ATP is made up of adenine and three phosphate groups. The bond between the second and third phosphate is broken down to generate energy.
Answer:
D. Weight varies with location, but mass does not vary
Explanation:
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
Where;
- m is the mass of the object.
- g is the acceleration due to gravity.
Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
<em>Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.</em>
Answer:
I think it is: C
Consist of both DNA and Protein
Explanation:
The reason why i say C is because Eukaryotic chromosomes consist of a DNA-protein complex that is organized in a compact manner which permits the large amount of DNA to be stored in the nucleus of the cell. The subunit designation of the chromosome is chromatin. The fundamental unit of chromatin is the nucleosome.
Some fun fact to me is that you can compare the cell to a factory - I always found it interesting. So the nucleus would be like the CEO, and the Endoplasmic Reticulum (ER) is like an assembly line - it's actually quite similar to a line like this!. And Ribosomes are the workers on this line.
