Answer:
The foam was found higher where the water temperatures were higher, then continued the height of the foam where the water was cold and lastly the ice water.
Explanation:
Yeasts undergo alcoholic fermentation, and perform a chemical reaction consisting of the following conditions:
That there is a substrate, that is, some reagent that the yeast can metabolize to give ethanol as a product, in this case it is sugar.
That there is a relatively anaerobic medium, that is why it is closed with film.
That the sea temperature approximately 30 degrees Celsius so that the fermentation is favored.
The bubbling that we see is nothing more than the chemical reaction that the yeast fungus produces when metabolizing the carbohydrate, which in this case is type A sugar, to give ethanol as a product. This chemical reaction releases gaseous components as fermentation occurs, that is, the more bubbling, the faster the reaction and the better the fermentation.
In the situation where the water was freezing and the foam or bubbling was lower regardless of whether it was closed by a plastic, because the extremely low temperature in the water slowed down the reaction rate of alcoholic fermentation.

Which of the following statements associated with cellulose is false? A) It's a linear polymer of glucose. B) The glycosidic linkage is β(1 → 4). C) Hydrolysis is accomplished enzymatically by cellulase. D) Most animals can easily digest this compound.
Answer:
Most animals can easily digest this compound
Explanation:
Cellulose is a linear polymer of glucose comprising of beta 1,4-glycosidic linkage of glucose molecules; this is where it differs from starch. Cellulose is a polysaccharide made of glucose monomers just like starch. The enzymatic hydrolysis of cellulose is achieved by the enzyme cellulase.
Not all animals can digest cellulose. As a mater of fact, no vertebrate can digest cellulose directly. Many herbivorous animals possess symbiotic bacteria in their gastrointestinal tract which enables the digestion of cellulose. These bacteria possess the requisite enzymes for the digestion of cellulose.

Why don’t populations of organisms that reproduce asexually have the same genetic variation as populations that reproduce sexually
Answer:
Asexual reproducing populations only get their genetics from a single parent, meaning that they all have the exact same DNA/RNA, while sexually reproducing populations have two parents meaning they get genetic code from two parents instead of one, therefore they have more variance. This variance is also the reason sexually reproducing populations are usually harder to wipe out due to variance.
Hypothesize about tumor growth. Scientists have shown that tumor growth is an example of positive feedback loops. Why is tumor growth an example of positive feedback? In your answer elaborate using the following terms stimulus, receptor, control center, effector, response.
Answer:
The connection between cancer cells stimulates uncontrolled proliferation and tumor growth
Explanation:
In the tumor, cancer cells are interconnected by different types of proteins, which may act as receptors or amplify oncogenic signals. For example, in breast cancer, it has been shown that oncogenic cells are often connected through E-cadherin proteins that mediate their adhesion, thereby stimulating the cell movement and invasion (characteristic of tumor metastasis). In this case, E-cadherin membrane proteins function by enhancing effector response in cancer cells. The nucleus acts as the control center of the cell that modulates the expression of tumor suppressor genes in order to inhibit tumor metastasis.

an Association between the root noodles of leguminous plant and rhizobium SP is known as what
Answer:
The question lacks options, the options are:
A. commensalism
B. mycorrhiza
C. parasitism
D. symbiosis
The answer is D, symbiosis (mutualism)
Explanation:
Organisms of same or different species interact with one another in their natural environment. The relationship between two organisms interacting with one another is called SYMBIOSIS. Symbiosis can be of different types depending on the effect of the relationship on the involved organisms. Symbiosis can be mutualistic, commensalistic or parasitic.
Mutualism is a kind of symbiosis in which the involved organisms benefit from the actions of one another. This is a case of the association between the root nodules of leguminous plant and rhizobium species.
Rhizobium is a bacteria genus found in the soil. They form nodules by attaching to the root of leguminous plants, which helps the plants to fix atmospheric nitrogen i.e converting gaseous nitrogen to a usable form (ammonia). In return, the plants provide organic acids for the Rhizobia bacteria, which they use as carbon and energy source. Hence, the association is a symbiotic relationship and specifically a mutualistic one.
The answer is no mycorrhiza because it is an association between a FUNGUS and a plant.

Lipids provide about
kJ/g of energy and are stored in
A. 19, granules
B. 36, triglycerides
C. 38, adipose tissue
D. none of these is correct
Answer:
C. 38, adipose tissue
Explanation:
Lipids/fats are one of the three energy storing biomolecules in living systems; the other two being carbohydrates and proteins. Three of them supply energy when oxidized but the amount of energy differs with lipids providing the most amount of energy.
Lipids provide 9 calories of energy per gram when oxidized, which is about 38Kj/g (where 4.2kJ = 1 calorie). Also, lipids or fats are stored throughout the body, specifically in connective tissues called ADIPOSE TISSUES.
What is the basic purpose of cellular respiration? What are the reactants and products of cellular respiration overall? Also, give a basic description of the three main stages of cellular respiration (glycolysis, Kreb cycle, and the electron transport chain)
Answer:
The Main basic purpose is to be able to breath and live. Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.The three main stages of cellular respiration (aerobic) would include Glycolysis, the Krebs Cycle and the Electron Transport Chain. The Krebs Cycle takes Citric Acid which is a derivative of Pyruvic Acid and converts this through 4 cycles into Hydrogen, carbon dioxide and water in the Mitochondrial Matrix.

What is true about the most recent ice age?
O A. All life on Earth became extinct.
O B. It occurred during the Precambrian era.
O C. Sea levels rose over 300 feet.
D. Land bridges existed that are now underwater.
The truth about the last ice age: D. There was now a submerged overpass.
An ice age also called an ice age, is a geological period in which thick ice sheets cover vast land areas. These massive ice ages could last for millions of years and could radically change the surface topography of entire continents.
There have been several major ice ages in Earth's history. The amount of sunlight reaching Earth over thousands of years varies considerably, especially at the North Pole and its surrounding northern latitudes. When less sunlight reaches northern latitudes, temperatures drop, more water freezes into ice, and the Ice Age begins. This ice age began about 2.6 million years ago in a period known as the Pleistocene epoch and lasted until about 11,000 years ago. Like everything else, the Last Ice Age brought about a series of glacial advances and retreats. In fact, we are technically still in the Ice Age.

acteriophages were labeled with radioactive phosphorous (32P) and sulfur (35S). The labeled bacteriophages were then allowed to infect their host cells. At the end of the experiment, the 32P label was found only inside the host cells and the 35S label was found only outside the host cells. This experiment shows that:
Answer:
They concluded that DNA is a genetic material.
Explanation:
This experiment shows that the DNA is genetic material. For performing experiments, the DNA of bacteriophages is labelled with radioactive phosphorous (32P) and proteins were labelled with sulfur (35S) in order to detect the action of bacteriophages. The bacteriophages attack on the bacteria by inserting its DNA in the bacteria. We can see this because radioactive phosphorus is present in DNA of bacteriophages while the protein did not enter into the bacteria and remain outside the cell and we can see it because protein is made up of sulphur.
