why is it advantageous for cells to switch to anaerobic fermentation in the absence of oxygen
[tex]\huge \mathbf{ \colorbox{black}{ \color{white}{Hello!}}} \boxed{♡} \Huge{►}[/tex]
How cells extract energy from glucose in the absence of oxygen. In yeast, anaerobic reactions produce alcohol, while in your muscles, they form lactic acid.
it is advantageous for cells to switch to anaerobic fermentation in the absence of oxygen because Anaerobic processes in yeast produce alcohol, whereas they produce lactic acid in your muscles.
What is anaerobic fermentation?
Generally, Once the oxygen is removed from the fermentation vessel and replaced with N2, CO2, etc of the fermentation, anaerobic fermentation begins.
In conclusion, Anaerobic processes in yeast produce alcohol, whereas they produce lactic acid in your muscles.

In 3–5 sentences, explain how genetic modification helps provide food for a growing population.
Given what we know about genetics, we can confirm that genetic modification helps provide food for a growing population by allowing us to create faster-growing crops that yield more.
What is genetic modification and how can we use it?Genetic modification, in simple terms, is when a scientist affects the genetic code of an organism to bend it towards our specific desires. This can be very dangerous and is very controversial in some cases. However, it can also be very beneficial in terms of food supplies. Gene modification can be used to create crops that will take less time to grow, and grow into bigger foods, allowing us to feed more people.Therefore, we can confirm that gene modification helps provide food for a growing population by forcing crops to be more efficient and feed more people.

What is the plasma (cell) membrane? What is its main function?
The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment.
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

What does the atomic number tell you about the element?
O number of protons
number of electrons
O number of neutrons
O total number of neutrons and protons
Answer:
These two numbers are fixed for an element. The mass number tells us the number (the sum of nucleons) of protons and neutrons in the nucleus of an atom. The atomic number (also known as the proton number) is the number of protons found in the nucleus of an atom. It is traditionally represented by the symbol Z.

hans and zacharias janssen contribution to cell theory
Answer:
1590’s
What year did Hans and Zacharias Janssen contribute to the cell theory? Hans and Zacharias Janssen are known for inventing the compound optical microscope. They made it in the 1590’s. This contributed to “The Cell Theory” by making it easier and more practical whilst observing cells.
Explanation:
Cell theory states that all biological organisms are made up of cells, which is the structural and functional unit of life.
Scientists Hans and Zacharias Janssen invented the compound microscope that played a vital role in observing cellular functions.
Hans and Zacharias Jansen invented the compound microscope, which consisted of the eyepiece and an objective lens.
The scientists discovered the compound microscope in the late 16th century, which then helped many scientists to magnify and observe the microscopic structures.
Thus, the Janssens discovered the compound microscope.

what will happen to a population of organisms that are in an oxygen rich environment. (Double click the story board to draw on it)
Answer
I'll assume this means adding additional oxygen to the atmosphere.
Paper airplanes now fly farther. With all that extra air, the air pressure near the surface increases significantly. Gliders, parachutists, birds and paper-plane hobbyists enjoy greatly improved performance.
Everyone gets better gas mileage. Oxygen-enriched air improves engine performance by producing hotter reactions and reducing the proportion of nitrogen, which reduces heat transfer (Page on Energy.gov)
Higher elevation Biomes become inhabited by more vertebrates. Areas such as the high Himalayas or high Andes are no longer off-limits to animals without special adaptations to increase their levels of hemoglobin.
Insects of unusual size. Many insects rely on gaseous diffusion to for respiration, therefore the maximum body size depends on the proportion of oxygen gas in the atmosphere. Most bugs get bigger, some smaller (see Atmospheric oxygen level and the evolution of insect body size)
Everyone feels more alert, active, and happier. All that fresh oxygen improve our cognition, alertness, and physical performance. As a result, most athletic records would likely be broken by oxygen-enriched athletes.
We get sick less often. Neutrophils, soldiers of the immune system, destroy bacteria by using NADP oxidase to pump ions into, and disrupt, intruding cell's membranes causing rupture. More oxygen, more oxidase. (Page on Nih.gov)
We die younger. Free radicals (i.e. O2-) are thought to exacerbate the aging process through Oxidative stress, which interferes in numerous cellular processes: protein production, DNA replication, intercellular communication, and are also thought to contribute to MS, Alzheimers, Parkinsons, and a host of other ailments.

Image result for why do you think it is important to understand chemistry and chemical cycles
Chemical cycling plays a large role in sustaining planetary atmospheres, liquids and biological processes and can greatly influence weather and climate. Some chemical cycles release renewable energy, others may give rise to complex chemical reactions, organic compounds and prebiotic chemistry.
Chemical reactions help us understand the properties of matter. By studying the way a sample interacts with other matter, we can learn its chemical properties. These properties can be used to identify an unknown specimen or to predict how different types of matter might react with each other
