Answer:
The correct answers are: A single diseased cell can multiply into a new tumor; cancer cells can travel through the blood and spread into new areas; many cancer cells multiply so fast that new tumors can form.
Explanation:
Cancer is the term that groups different conditions that have all one thing in common: there's an abnormal cell growth that can potentially irradiate to other parts of the body.
A single diseased cell can develop a tumor, because this abnormal cell has the capacity to replicate so fast and, of course, transmit its abnormality to every other cell that it generates.
These abnormalities occur because there is some sort of damage in the DNA of a cell, which most of the time is detected by the body and eliminated - but when it's not, the cell quickly multiplies itself and generates a tumor. The difference between a benign tumor and cancer is that cancer can spread through the body and a benign tumor can not.
Cancer is very dangerous and potentially fatal if not treated fast because it can travel through the bloodstream or the lymphatic system and invade other organs, causing metastasis.
There's a lot of research being done on how to cure cancer, but the disparities in every different type of cancer make finding the solution much harder. Nowadays, depending on the type of cancer and the stage where the cancer is, this condition can be treated with radiotherapy, chemotherapy, or surgery.

What causes a water molecule to be polar? (3 points)
In science, a theory is different from how we use the term "theory" to apply to everyday ideas. The statement "It’s only a theory" might mean something very different than "theory" when used as a scientific term. What is the best way to explain the word, "theory" when used in science?
A. In science, there is no difference between a law and a theory.
B. In science, there are few principles that can be considered theories.
C. In science, a theory is well supported by observations and/or experimental data.
D. In science, a theory is a completely accurate and reliable fact about natural events.
Answer:
C
Explanation:
The correct answer would be that in science, a theory is well supported by observations and/or experimental data.
Theories are usually derived from testing hypotheses. Untested statements from observations are referred to as theories. When hypotheses are tested using a series of independent experiments and found to be true, they become theories.
Hence, theories are well supported by observations and data in science. A theory remains accurate for as long as there are no contradictory findings to it. Theories can, however, be modified once there are data to back them up.
The correct option is C.

Which best explains how to oxygen Atoms,
each with six valence electrons can bond with each other?
Explanation:
Two oxygen atoms bonds with each other via covalent bonding.
In the formation of covalent bonds, two atoms with little to no electronegativity difference combines by sharing of the valence electrons. This why homonuclear molecules can be formed.
Two atoms of the same kind having zero electronegativity difference forms this covalent bonds. There is equal sharing of electron pair between the atoms and there is no electrostatic charge on the molecule.For the oxygen atom with 6 valence electrons;
two electrons are shared by each atoms to make a complete octet and a stable molecule.

Explanation:
A basketball with a mass of 0.60 kg is accelerated with a force of 10.8 N. If resisting forces are ignored, what is the acceleration of the basketball to the nearest m/s2?
Answer:
18 m/s^2 A newton is defined as kg*m/s^2 and you want to accelerate a mass in kg, getting a result of m/s^2. So what you need to do is cancel out the kg unit in the newtons. You can do that by dividing the newtons by kg. So let's do the math. 10.8 kg*m/s^2 / 0.60 kg = 18 m/s^2 So the ball has an acceleration of 18 m/s^2. Remember, look at the units you have and the units you desire. By doing so, the math operations become obvious.

What would be the main problem with reproduction if meiosis did not take place to form sex cells?
Answer:
Fertilization would result in a zygote with twice as many chromosomes as the parents.
Explanation:
Meiosis creates four haploid cells from a diploid parent cell. These haploid cells are the sex cells - sperm cells and egg cells.
Since these cells are haploid (containing 23 chromosomes, half the amount of chromosomes as the parent diploid cells), when they fuse during fertilization, they form a diploid zygote containing 46 chromosomes.
Answer:
B) Fertilization would result in a zygote with half as many chromosomes as the parents.
Explanation:
Exchange of oxygen and carbon dioxide in the lungs uses which mode of cellular transport?
a
endocytosis
b
facilitated diffusion
c
filtration
d
simple diffusion
Answer:
D: Simple Diffusion
Explanation:
Diffusion is a transport driven by a concentration gradient. Gas molecules move from a place of high concentration to an area of low concentration. Knowing when blood is low in concentration and high in carbon dioxide it goes under gas exchange with air into the lungs.

Certain materials are needed by the mitochondria to make energy. Which of the following is most responsible for getting the
materials into the cell?
O A The materials need to Love through the cytoplasm to get to the mitochondria
B The cell membrane lets the materials into the cell so they can get to the mitochondria
OCThe cell wall lets the materials into the cell so they can get to the mitochondria
D. The materials need to move through the lysosome to get to the mitochondria
Answer:
C. The cell membrane lets the materials into the cell so they can get to the mitochondria
Explanation:
The cell membrane regulates the entrance and exit of certain molecules inside the cell. Some molecules can easily pass through the phospholipid bilayer via passive transport. Others use protein channels, and some require movement by active transport, or endocytosis.

Explanation:
Volcanoes are usually formed as a result of _____.
a transform fault boundary, where both plates are oceanic
a convergent boundary, where both plates are continental
a convergent boundary, where at least one of the plates is oceanic
a divergent boundary, where at least one of the plates is oceanic
Answer:
a transform fault boundary, where both plates are oceanic
Explanation:
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope.
Answer:
a transform fault boundary, where both plates are oceanic
