Troposphere is the layer of atmosphere that is present near to the earth surface whereas exosphere is the layer of atmosphere that is present farthest from the earth surface. Troposphere is the layer where weather of the earth is present. The mesosphere is the layer of the atmosphere that protects the Earth from meteoroids. Crust is the part of the earth on which we walk. oceanic crust and continental crust are the two types of crust. Mantle is the layer in which convection currents occurs. Convection currents refers to the rising of hot magma and sinking of cool magma. Sun is the source of energy and all energy comes to the earth from sun.

kinetic energy

Answers

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

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

Answers

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.

Answer: Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.

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

Answers

Answer:

the answer is b

Uncontrolled 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.

Which of the following is evidence that cells no longer respond to external factors and may have turned cancerous?

A. New cells replace old or damaged cells.
B. Cell clumps form, crowding existing cells.
C. Dead cells are shed at a more rapid rate.
D. Dormant cells re-enter an active cell cycle.

Answers

Answer:

option C will be the correct answer

Dead cells are shed at a more rapid rate is evidence that cells no longer respond to external factors and may have turned cancerous.

What are the cancer cells?

Cancer cells are defined as cells which divide continually, forming solid tumors or flooding the blood with abnormal cells. Cell division is a normal process used by the body for growth and repair.

Sometimes this orderly process breaks down, and abnormal or damaged cells grow and multiply when they shouldn’t. These cells may form tumors, which are lumps of tissue.

Answers

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

Discuss the purpose of guard cells and stomata on the leaves of plants.

Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation.

Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.

Why is the reduction in chromosomes number important in meiosis?

Answers

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.

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.

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.

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.

Answers

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 nucleus

The mRNA binds to the transport proteins to form mRNA-protein complexes and is transported through the nuclear pores, often with the assistance of ATP.
