.A jogger with a mass of 81.6 kg is moving at 2.2 m/s. What is the jogger's
kinetic energy
Answer:
89.6Joules
Explanation:
Kinetic energy is 1/2MV^2
Where m is Mass and v is velocity.
M=81.6 v=2.2m/s
K.E= 1/2 × 81.6 × 2.2
= 81.6 ×1.1
K.E=89.6 Joules
Atoms from sugar molecules may combine with other elements via chemical reactions to form other large carbon-based molecules
Answer:
Yes.
Explanation:
Yes, carbon atoms from sugar molecules combine with other elements through chemical reactions to form other large carbon-based molecules. Sugar molecules comprise of carbon, hydrogen, and oxygen atoms. The hydrocarbon of sugar molecules are used to make amino acids and other carbon-based molecules that can be combine into larger molecules such as DNA molecule.

Q: What cellular mechanism causes cancer?
Select one:
a. cells produced with no DNA
b. uncontrolled cell division
c. defective cell membranes
d. cells produced without nuclei
Answer:
the answer is bUncontrolled cell division is a cellular mechanism which causes cancer, hence option B is correct.
What is cancer?A phrase for conditions where aberrant cells can infect surrounding tissues and divide uncontrollably. The lymphatic and vascular systems of the body are further routes by which cancer cells might spread.
Cancer is a condition wherein a few of the body's cells grow out of control. Cancer comes in many forms, and each one starts when a single cell experiences a genetic change (or mutation) that enables the cell to divide and multiply uncontrollably.
When one or more genes change and produce malignant cells, cancer begins. Tumors are formed by these cancerous cell groupings.
Therefore, cancerous cells may separate from tumors and spread to other parts of your body through your lymphatic system or circulation.

A key part of the Watson-Crick model came when Watson realized
that adenine could form hydrogen bonds with thymine and guanine
could form hydrogen bonds with cytosine. This explains why A=T
and G C in Chargaff's rules. Also, these two hydrogen-bonded
nucleotide pairs had the exact same width, so they could form the
rungs of the DNA ladder.
The fact that these pairs could match up only in this way meant that
the sequence of bases in one strand could determine the sequence
of bases in a second strand created from the first. The second strand
is said to be complementary to the first strand. Individual bases are
paired so that the identity of any base determines the identity of the
base paired with it; that is, the complementary base.
This table lists the base abbreviations for bases in a sample of single-
stranded DNA. Fill in the second column with the base abbreviations
that are complementary to the given bases.

Explanation:
A always pairs up with T
C always pairs up with G
A - TT - AT - AC - GA - TG - CG-CC - GT - AA - TA usually pairs up with TC usually pairs up with GThese are bases of amino acids called nucleotides sequences. And this helps in the bond of several base pairs to their nucleotide sequence.What is the Watson-Crick model?
In “A Structure of Deoxyribose Nucleic Acid,” Watson and Crick defined DNA as a double helix that contained long, helical strands wound together. In their model, every DNA strand contained personal devices referred to as bases, and the bases alongside one DNA strand matched the bases alongside the opposite DNA strand.
Thus it is clear that the above answer is well explained.

Earth's gravity and Bill act on the box in opposite directions. Bill acts with a smaller force than Earth's gravity does. Because these opposing forces are different sizes, they are unbalanced forces.
How do these forces affect the motion of the box?
Answer:
The force with more force (gravity) will have much more effect than the force with less force (Bill) and the box will go in the motion that the greater force makes it go.
