Normal cells become cancer cells when
1. regulation of cell growth and division is lost.
2.All of the above
3.cells do not respond normally to control mechanisms.
4.cells continue to divide without passing through G1.
Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

a _____ is an organism that cannot produce its own food, so it must obtain its energy by eating or other organisms
Answer: Heterotrophs
Explanation: Heterotrophs, also known as other-feeders, can't capture light or chemical energy to make their own food out of carbon dioxide. Humans are heterotrophs. Instead, heterotrophs get organic molecules by eating other organisms or their byproducts. Animals, fungi, and many bacteria are heterotrophs.

Why does diuron cause coral to bleach
Simple answer:
When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.
More in depth explanation:
Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.

Before conducting an experiment, a scientist needs to review _____.
Answer:
post a testable question
state hypothesis
Answer:
make sure they have a testable question
Explanation:
In the 1970s, public opinion favored cleaning up the environment. Since the 1980s, some members of Congress and industry leaders have fought against environmental laws that regulate the amount of pollution that can be added to the environment. Are they working in the best interests of the public or of corporations?
Answer:
They are working in the best interests of corporations
Explanation:
Corporations and industries are responsible for a large percentage of environmental pollution being witnessed in several regions of the world. The pollutions have negative consequences for the environment and the organisms living in it, including humans. Hence, formulating laws to regulate the amount of pollution that can be added to the environment is in the best interests of the public. Any person that fights against these laws is likely working in the interests of industries and corporations and not the public in its entirety.

How would the levels of organization in the body work to get the marching band member back to being uninjured? Does homeostasis in and between cells help to return organ systems and the organisms as a whole back to homeostasis?
Answer:
Repairing ability and homeostasis causes the injured parts to return back to uninjured.
Explanation:
Due to repairing ability of levels of organization in the body helped the injured parts to return back uninjured. Yes, homeostasis that is present in and between cells help to return organ systems back to homeostasis or equilibrium state of the body. Our body has the ability to main homeostasis whenever some disturbance occur in the body. If this homeostasis not present our body, there will be no repairing of damaged occurs.
It should be noted that the repairing ability and homeostasis are vital as they cause the injured parts to return back to being uninjured.
Homeostasis simply means the process that living things use to maintain stability while they adjust to the conditions that are best for their survival.
The homeostasis that is present in and between cells is vital for returning systems back to the equilibrium state of the body. The body of an individual has the ability to maintain homeostasis whenever there is some disturbance that occurs in the body.

A botanist discovers a new species of plant in a tropical rainforest. Its characteristics include flagellated sperm, presence of xylem for conducting water, independent gametophyte and sporophyte stages, no seeds. This plant is most likely a
Answer:
Fern
Explanation:
The plant discovered by the botanist is most likely a fern.
Ferns are referred to as seedless vascular plants. They do not produce seeds and they possess vascular tissues in the names of xylem and phloem. The xylem conducts water/mineral salts from the roots to the body of the plant while the phloem distributes manufactured foods from their sources to other parts of the plant.
Ferns also have independent gametophyte and sporophyte stages. The sporophyte produces haploid spores through meiosis which then germinates to the gametophyte. The gametophyte produces male and female gametes - antheridium and archegonium. The antheridium is motile and swims to meet the immotile archegonium during fertilization to produce the zygote which then divides mitotically to give the sporophyte.

Answer:
HeLa cells are a great find in the science community and Henrietta Lacks' unique cells are still helping us today. They are perfect for important studies such as cancer, cell biology, genetics, and infectious diseases. Since now we have these unique immortal cells it is quite easy to start any scientific testing on human cells since their is an endless supply. Personally, I believe Henrietta Lacks will live on forever as a hero and mother of modern scientific advancements, since she quite literally, grew all of the modern cell research we have today.

1. "For oxygen to enter the blood, how must the concentration of O2 in the alveoli compare to O2 in the blood?" 2. "For carbon dioxide to leave the blood and enter the alveoli, how must the concentration of CO2 in the blood compare to CO2 in the alveoli?" 3. "When diffusion has reached equil- ibrium, we say that the net movement of the molecules is zero. Does movement stop? Explain."
Answer:
1. Concentration of O2 in the alveoli must be more than that of the blood
2. Concentration of CO2 in the blood must be more than that of the alveoli
3. Movement does not stop (find the explanation below).
Explanation:
Gaseous exchange i.e. taking in of O2 and taking out of CO2, takes place in the alveoli/air sac of the lungs. However, the movement in and out of O2 and CO2 from the alveoli into the bloodstream and vice versa follows the principles of SIMPLE DIFFUSION. Diffusion is the process whereby substances move from a region of high concentration to a region of low concentration until they are evenly distributed. Based on this, the following will occur:
1. The concentration of O2 in the alveoli must be more than that in the blood in order for oxygen to enter the blood via diffusion.
2. The concentration of CO2 in the blood must be more than that in the alveoli in order for carbon dioxide to leave the blood and enter the alveoli via diffusion.
3. When the rate of diffusion is at equilibrium i.e. no net movement is occuring die to equal concentration of the substance on both sides, the substances begin to move in the opposite direction at an equal rate. Note that, at equilibrium, MOVEMENT DOES NOT STOP, however, there is an equal rate of movement.

Would a greater or less amount of exposed surface area absorb thermal energy faster? Why? Give an example.
Answer:
Explanation:
A greater amount of surface area exposed will absorb thermal energy faster compared to a surface with a lesser exposed area.
Thermal energy is a form of kinetic energy in which the molecules of a medium increases their velocity.
In a large area with high surface are exposed, the molecules are spread out openly without obstructing each other. This will enable a faster thermal conduction through a system. A small exposed surface area inhibits thermal conduction. Solar panels are designed to expose more surface area to abstract more thermal energy.

Which substance increases its volume when it becomes a solid?
A. Mercury
B. Water
C. Salt
Answer:
B
Explanation:
when water is frozen, it expands, something to do with anomolous expansion of water.
Water increases its volume when it becomes a solid.
Define volume and its units?Volume is a measure of occupied three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
The surface-area-to-volume ratio, also called the surface-to-volume ratio and variously denoted sa/vol or SA:V, is the amount of surface area per unit volume of an object or collection of objects.
If volume is the amount of 3-D space contained by a closed surface (e.g. the amount of space within a given cube, or cylinder, or any other 3-D shape), liquid volume is a way to measure an amount of liquid by describing it how much 3-D space it occupies.
