Do you think an advanced civilizations may exist in the universe? Why or why not?
Answer:
Many other planets throughout the universe probably hosted intelligent life long before Earth did, a new study suggests.
The probability of a civilization developing on a potentially habitable alien planet would have to be less than one in 10 billion trillion — or one part in 10 to the 22nd power — for humanity to be the first technologically advanced species the cosmos has ever known, according to the study.
"To me, this implies that other intelligent, technology-producing species very likely have evolved before us," said lead author Adam Frank, a professor of physics and astronomy at the University of Rochester in New York. [13 Ways to Hunt Intelligent Alien Life]
In 1961, astronomer Frank Drake devised a formula to estimate the number of extraterrestrial civilizations that may exist today in the Milky Way.
Adam Frank and co-author Woodruff Sullivan of the University of Washington were interested in the odds that intelligent aliens have ever existed anywhere in the universe. So they tweaked the famous Drake equation, coming up with an "archaeological version" that doesn't take into account how long alien civilizations may last.
Frank and Sullivan also incorporated observations from NASA's Kepler space telescope and other instruments, which suggest that about 20 percent of all stars host planets in the life-friendly, "habitable zone," where liquid water could exist on a world's surface.

Microscopes use lenses to magnify objects. A simple microscope uses only one lens; a magnifying glass could be called a simple microscope. The magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. A hand-lens, for example, might be labeled with 10x, meaning the lens magnifies the object to look ten times larger than the actual size.
Which of the following molecules are classified as carbohydrates?
The molecules classified as carbohydrates are oligosaccharides, monosaccharides, disaccharides.
What are the carbohydrates?
Carbs, or carbs, are sugar particles. Alongside proteins and fats, starches are one of three fundamental supplements tracked down in food varieties and beverages.
Your body separates starches into glucose. Glucose, or glucose, is the principal wellspring of energy for your body's phones, tissues, and organs. Glucose can be utilized right away or put away in the liver and muscles for sometime in the future.
There is nobody size-fits-all measure of starches that individuals ought to eat. This sum can differ, contingent upon variables like your age, sex, wellbeing, and whether you are attempting to lose or put on weight. Overall, individuals ought to get 45 to 65% of their calories from carbs consistently.

The question in her mind, and one not easily solved, now was, 'How can I get away?' So, as was her usual custom, she 'told God she was afraid to go in the night, and in the day every body would see her.' At length, the thought came to her that she could leave just before the day dawned, and get out of the neighborhood where she was known before the people were much astir. 'Yes,' she said, fervently, 'that's a good thought! Thank you, God, for that thought!' So, receiving it as coming direct from God, she acted upon it, and one fine morning, a little before day-break, she might have been seen stepping stealthily away from the rear of Master Dupont's house."

x³-7x+6
Hint:x³-7x+6=0
Answer:
(x - 1)(x - 2)(x + 3)
Explanation:
f(x)=x3-7x+6 Since (a + b + c + d = 0), then f(1) = 0 --> one factor if (x - 1).
After division -->
f(x)=(x-1)(x2f2+x-6). The trinomial in parentheses can be factored.
Find 2 numbers knowing sum (1) and product (-6). They are -2 and 3.
Therefor, f(x)=(x-1)(x-2)(x+3)

What is your opinion on the use of stem cells, obtained from fertilized eggs or early stage embryos
USE OF STEM CELL:
The first attempts to turn mature cells back into pluripotent stem cells involved a process called cloning. In the cloning process, an egg is fertilized in the lab, and right after fertilization, the DNA is removed from the egg.These stem cells come from embryos that are three to five days old. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.Despite the potential benefit of using human ES cells in the treatment of disease, their use remains controversial because of their derivation from early embryos.Learn more:

Which of the following statements about muscles and the muscular
system is true?
O The three types of muscle tissue are skeletal muscle, smooth muscle, and involuntary
muscle.
O Muscles always work independently to move parts of the body.
All muscle action is voluntary, or able to be consciously controlled.
OSmooth muscle moves food through the digestive system.
Smooth muscle moves food to the digestive system, which is the true statement about the muscle and muscular systems. Hence, the fourth option is the correct answer.
What are different types of muscles?In the human body, there are three types of muscles: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle is called voluntary muscle.
Voluntary muscles move in response to commands. Examples are the muscles of the hand and legs. They move when an organism wants to move. Cardiac muscle and smooth muscle are involuntary in nature.
The contraction and relaxation of involuntary muscles don't depend on the individual's wish. Smooth muscles are present in the internal organs such as the intestine, stomach, etc. When food reaches the stomach, the stomach muscle contracts and relaxes to digest the food. The cardiac muscle is present in the heart. It always works.
Hence, option 4 is the correct answer, as smooth muscle moves food through the digestive system.

Glycolysis is the splitting, or lysis of glucose. Glycolysis converts the 6-carbon glucose into two 3-carbon pyruvate molecules. This process occurs in the cytoplasm of the cell, and it occurs in the presence or absence of oxygen. During glycolysis a small amount of NADH is made as are four ATP.
