.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

Why is the reduction in chromosomes number important in meiosis?
Explanation:
Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical — without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.

Dutch elm disease is a disease of elm trees caused by a fungus. The fungus lives off water and nutrients from the tree. It spreads through water-conducting vessels in the
tree. Gum forms within these vessels in response to the fungus, and the tree weakens and dies. Beetles spread the fungus from infected trees. What is the relationship
between the fungus and the elm tree?
A. predator-prey
O
B. mutualism
C. commensalism
D. parasite-host

Explanation:
DNA is found in the nucleus of eukaryotic cells and the ribosomes, the location where proteins are made, are found out in the cytoplasm of the cell as show below. Explain why this is a problem and how the cell solves this problem.
Answer:
See the answer below
Explanation:
The DNA of eukaryotic organisms being present in the nucleus while the protein-synthesizing organelle, the ribosome being present in the cytoplasm poses a spatial problem. It means that transcribed DNAs (messenger RNA) in the nucleus would have to somehow be transported to the ribosome in order for the cell to successfully synthesize proteins.
The problem of transporting the messenger RNA is solved by two features of the cell:
The presence of pores in the nuclear envelopThe presence of transport proteins in the nucleusThe mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP.

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.

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.

A–T
G–C

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.

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.

Based on the the table of rock characteristics and your knowledge of the rock cycle, in which type of
rock (igneous, metamorphic, or sedimentary) would you expect to find bubbles or a smooth, glassy
surface? Why?
HELPPPP ASAP
Answer:
The answer would be igneous. But there are two types of igneous rocks. One is Intrusive, or Plutonic, rocks, and the other is Extrusive. Intrusive rocks crystallize from magma beneath the earth's surface. Extrusive or volcanic rocks crystallize from lava at the earth's surface. Either way, Igneous would have a bubbly, or a smooth, glassy surface.

circle with center at (-3, 7) and radius 8
Explanation:
Centre of the circle ( h,k)=(-3,7)
radius of the circle (r)=8
Equation of the circle is,
(x-h)^2+(y-k)^2=r^2
or,(x+3)^2+(y-7)=8^2
or,x^2+6x+9+y^2-2y+49=64
or,x^2+y^2+6x-2y+58-64=0
or,x^2+y^2+6x-2y-6=0 is the required equation of the circle
