Which statement best describes cancer cells?
They grow as a single layer of cells.
They cease to reproduce after 20–50 mitotic divisions.
They reproduce only when needed to replace missing cells.
They are not regulated by contact inhibition.
Answer: They are not regulated by contact inhibition.
Explanation:
Contact inhibition is a form of controlling cells. Cancer doesn't have contact inhibition, which is one of the reasons why it spirals out of place so easily.
Answer:
They are Not regulated by contact inhibition.
Explanation:
The other 3 options are not characteristics of a cancer cell. Cancer cells have unlimited cell division, no anchorage dependent inhibition, no contact inhibition, and forms tumors - hence they don't form a single layer of cells.
The average conversion energy from producers to primary consumers is a. 1% b. 10% C. 50% d. 100%
Answer:
The average conversion energy from producers to primary consumers is b. 10%.
Explanation:
This percentage actually holds true for all transfer of energy at any trophic level in the food chain. Majority of the energy loss can be attributed to metabolic processes that give off heat and other forms of energy. It is important to note that energy cannot be created nor destroyed, it is simply transformed from one form to another.

why birds are kept in aves class.?
Answer:
This is mostly because there were several non-bird dinosaurs that had wings. One of these was the Caudipteryx.
this should help
Answer:
living species evolved from reptiles, not mammals. However, they have adapted to fly. Aves are warm-blooded species with scales on their feet.
Which of these organisms is not matched to the main type of nitrogenous waste it excretes?
Reptiles−−uric acid
Terrestrial insects−−uric acid
Freshwater fishes−−ammonia
Marine fishes−−ammonia
The correct option is B -Terrestrial insects−−uric acid.
The species that is incompatible with the main sort of nitrogenous waste it excretes is an insect that lives on land. The correct response for terrestrial insects is "uric acid," not "ammonia."
The primary nitrogenous waste excreted by terrestrial insects, such as insects and spiders, is uric acid. Uric acid is a somewhat insoluble waste product that requires less water for excretion in organisms living in dry or terrestrial settings.
Hence option B is correct.

Which factor can decrease the rate of a chemical reaction?
A low activation energy
B high pressure
C low temperature
D high concentration of enzyme
(c)Low Temperature of the Reactants can decrease the rate of a chemical reaction.
How temperature effects the rate of a chemical reaction
Chemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Thus decrease in the temperature of a reaction can help in decreasing the rate of a chemical reaction.Lower the temperature lower the chemical reaction rate.

a common sign of pneumothorax is a shift of the trachea towards the affected lung as air pressure sucks the lung away from the midline
The statement is false that in pneumothorax there is a shift of the trachea towards the affected lung as air pressure sucks the lung away from the midline.
Pneumothorax is the condition where the lung collapses. All the air present inside the lungs is pushed out. There occurs a tracheal shift to the opposite side during the lung collapse, but the lung is not moved away from the midline.
Lungs are the main respiratory organ of the body. They are involved in the exchange of air from the blood. The lungs comprise of several very small air sacs called alveoli. These alveoli increase the surface area of the lung and hence increase the ventilation.

I am identical to all other cells like me that form after cell division. somatic or gametes?
You are most likely a somatic cell if you share all the same characteristics as all other cells that have undergone cell division.
What are cells?The fundamental building block of life, cells are the smallest living thing capable of performing all of life's essential tasks. They provide as the foundation for all living things, from simple single-celled microbes to intricate multicellular ones like plants and animals.
Somatic cells, which make up the body's tissues and organs, are not sexually reproducible. Through the process of mitosis, two identical daughter cells with the same genetic makeup as the parent cell are created.
Meiosis is a specific kind of cell division that is used to create gametes (the cells that make up sperm and eggs). With half as many chromosomes as the parent cell, each of the four genetically distinct daughter cells produced during meiosis are genetically distinct from one another. As a result, neither the parent cell nor the gametes are exactly the same.

When DNA is replicated or transcribed, accidents can happen, leading to a change in the base sequence.
● What do you think could cause such accidents to occur?
● How might the changes affect the reading frame? How might the encoded protein be affected?
A frameshift variant occurs when there is an addition or loss of nucleotides that shifts the grouping and changes the code for all downstream amino acids.
What do you mean by frameshift mutations?A frameshift mutation is a genetic mutation caused by indels of a number of nucleotides in a DNA sequence that is not divisible by three. Due to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame.
If a mutation disrupts this normal reading frame, then the entire gene sequence following the mutation will be incorrectly read. This can result in the addition of the wrong amino acids to the protein and/or the creation of a codon that stops the protein from growing longer.
A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. A DNA sequence is a chain of many smaller molecules called nucleotides.

complete the concept map to identify some of the enzymes involved in digestion including their source, the location in which they act, and the types of foods they digest. drag the appropriate labels to their respective targets.
Enzymes are proteins that catalyze chemical reactions in the body. Digestive enzymes are responsible for breaking down food into smaller molecules that can be absorbed by the body.
Some of the enzymes involved in digestion include:
Amylase - produced in the salivary glands and pancreas; acts in the mouth and small intestine to break down carbohydrates (starches and sugars).
Proteases - produced in the stomach and pancreas; act in the stomach and small intestine to break down proteins.
Lipases - produced in the pancreas; act in the small intestine to break down fats.
Maltase, lactase, and sucrase - produced in the small intestine; act to break down disaccharides (maltose, lactose, and sucrose) into monosaccharides (glucose, fructose, and galactose).
Nucleases - produced in the pancreas; act in the small intestine to break down nucleic acids (DNA and RNA).
These enzymes act in specific locations in the digestive tract, and they digest specific types of food molecules. For example, amylase acts in the mouth and small intestine to digest carbohydrates, while proteases act in the stomach and small intestine to digest proteins.
Overall, the digestive process is complex and involves a variety of enzymes produced by different organs in the body. The breakdown of food into its constituent molecules is essential for the body to absorb the nutrients it needs for growth, repair, and energy.

Edith Widder: Glowing life in an underwater world
1. On her first open-ocean dive in the Santa Barbara Channel, Widder says she dove down to 880 feet and turned off her lights. Explain why she did this and how she described what she saw?
2. If you happen to be on a ship and go to use the bathroom at night without turning on the light, why does Widder explain you might think you are having a “religious experience”?
3. Why are most people who are studying bioluminescence today focused mainly on the chemistry behind it? What does the Nobel Prize have to do with this?
4. What makes bioluminescence an important factor of survival for so many animals? Provide one example Widder gives to explain this.
5. Why is Widder dissatisfied with the way we explore the ocean? What are the two main ways we learn about what lives in the ocean that she describes?
6. How does Widder tell the difference between the species she observes in the deep ocean? Give an example of a species she identifies based on this observation.
Answer:
1. She turned off the lights because she knew that she would see a phenomenon of animals making light called bioluminescence. She described that she was totally unprepared for how much there was and how spectacular it was. She saw chains of jellyfish that were pumping out a lot of light; and puffs and billows of what looked like luminous blue smoke and sparks of blue light from the thrusters.
2. The head on ships which are the toilets on ships are flushed with unfilltered seawater that often has bioluminescent plankton on it. So, if you stagger into the haed late at night and you're toilet-hugging sick, that you forget to turn on the light, you my think that you're having a religious experience.
3. They are focusing on the chemistry because these chemicals have proved so incredibly valuable for developing antibacterial agents, cancer fighting drugs, testing for the presence of life on Mars, detecting pollutants in our waters which is how it is used at ORCA. In 2008, the Nobel Prize in Chemistry was awarded for work done on a molecule called green fluorescent protein that was isolated from the bioluminescent chemistry of a jellyfish, and it has been equated to the invention of the microscope, in terms of the impact that it has had on cell biology and genetic engineering.
4. What makes it important for the survival of many animals is for the animals that are trying to avoid predators by staying in the darkness, light can still be very useful for the three basic things that animals have to do to survive: and that's find food, attract a mate and avoid being eaten.
5. The primary ways that we know about what lives in the ocean is we go out and drag nets behind ships. The other primary way is we go down with submersibles and remote-operated vehicles. Doing that there are bright lights and thrusters that disturbs the animals and makes then go away.
6. She was able to tell the difference between the species by the types of flashes they produced like the big explosions, sparks, are from a little comb jelly.
