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:

Answer:
1:Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the only force acting on the object is gravity
2:Our universe began with an explosion of space itself - the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.
3:A scientific theory is an explanation of something in the natural world that is based on past observations and evidence.
4:In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.

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.

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.

Answer:
Codominance
Explanation:
That would be Codominance. Codominance means that neither allele can mask the expression of the other allele (Both are dominant alleles, no recessive alleles). This is because the flower isn't only red or only pink. It has both alleles (which causes the red and pink stripes).

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.
Which statement is an accurate description of genes? SC.912.L.16.3
Proteins are made of genes and code for DNA
Genes are made of proteins that code for nitrogen bases
DNA is made of carbohydrates that code for genes
Genes are made of DNA and code for proteins
Answer:
B
Explanation:
Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.
What are genes made up of?Genes are made of DNA and code for proteins.This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.
DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.
Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.
A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.
Therefore, Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.

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.

What are the characteristic feature of mitochondria ?
Mitochondria is commonly called as the “Powerhouse of the cell, these are double membrane-bound organelle present in most eukaryotic organisms located in cytoplasm and function as cell's “digestive system.”
They involve in break down of nutrients and generate energy-rich molecules, cellular respiration occur within the mitochondria, was first described by a German pathologist named Richard Altmann in the year 1890.
The mitochondrion is rod-shaped structure found in both plant and animal cell, size ranges from 0.5 to 1.0 micrometre in diameter, consist outer membrane, an inner membrane, and a gel-like matrix.
The outer and inner membrane are composed of proteins and phospholipid layers which is separated by the intermembrane space.
