The kinetic energy of 6250 J equals 6250 J work-done in stopping the object in motion.
The given parameters;
- <em>Kinetic energy, K.E = 6250 J</em>
According to work-energy theorem, the work done in stopping a moving object is equal to the kinetic energy of the moving object.
Kinetic energy is the energy possessed by an object by virtue of its state of motion.
Work-done in stopping the object in motion = K.E = 6250 J.
Thus, we can conclude that the kinetic energy of 6250 J equals 6250 work-done in stopping the object in motion.

Answer: Cells undergo cell division
Explanation:
"As humans grow, their bodies change.” The statement that best explains how humans grow is that cells undergo cell division.
When cells divide, thus brings about the making of new cells. This is referred to as cell division or cell reproduction. In this case, a single cell divides and then brings about two cells, then these two cells later make four cells .... This is unique and vital for every living organisms.
carbon dating shows how old a bone is by measuring the amount of carbon 12, and carbon 14 that the bone contains. and because carbon 14 is not replaced by exchange with the atmosphere the ratio of c12:c14 (the ratio of carbon 12 to carbon 14) tells how old the bone is by comparing the amount of carbon 14 to the amount of carbon 12. carbon 14 has a half life of 5,700 years, while carbon 12 is stable and does not radioactively decay at all.
Answer:
The answer is A.
Explanation:
B) Nucleotides and amino acids can act as extracellular signal molecules:
ATP is made of adenosine (a type of nucleotide) and used in cell signalling called "purigenic signalling" and amino acids are also used as signal molecules.
C) Some signal molecules are transmembrane proteins:
Transmembrane acts as receptors for smaller signal molecules so this can also be accepted as true.
D) Some signal molecules can bind directly to intracellular proteins that bind DNA and regulate gene transcription:
That is also true, some of the hormones can cross lipid membrane of the cells and bind directly to the intracellular (inside-of-a-cell) proteins.
Lastly; dissolved gasses such as nitric oxide can activate proteins such as guanylyl cyclase so this choice is <u>false</u>.
Answer:
No, this is not consistent with the principle of independent assortment.
Explanation:
The principle of independent assortment states that alleles from different genes assort independently. This means that if a plant has a genotype Aa Bb, all four alleles (A, a, B, and b) are going to segregate equally, so we will have the following four gametes after meiosis:
- AB
- Ab
- aB
- ab
If the researcher finds that two of the four products are AB, probably there would be a deviation of Mendel's laws.
