lubasha [3.4K]

Answer:

See the answer below

Explanation:

<em>The lessons that can be learned from this floating pile of trash is that indiscriminate disposal of waste into the environment by humans can eventually come back to haunt them.</em>

What led to the floating pile of trash is the indiscriminate disposal of wastes into the environment. These wastes eventually find their way to the ocean, damaging the aesthetic appearance of the water, poisoning aquatic biodiversity, and eventually poisoning the humans that consume the aquatic foods that make it out of such water alive.

You are growing yeast cells in a culture. After a few days of consistent growth, you notice that cell growth has slowed consider
BigorU [14]

The correct answer is C) There is not enough oxygen in the culture medium. This is because of alcoholic fermentation, and anaerobic process where the yeast transform sugar (glucose) in ethylic alcohol (ethanol) and carbon dioxide. Glucose is decomposed into pyruvic acid which then after turns into CO2 and ethanol. The bubbles described, are produced by the carbon dioxide.

The yeast, as well as some bacteria, use the glucose molecule through "glycolysis"  to obtain a 3-carbon molecule called pyruvates. Glycolysis consists of 10 coupled reactions, in the end, from one glucose (6 carbons) the yeast will obtain two pyruvates (3 carbons each).

Pyruvate can follow three main routes to obtain ATP, end up as lactate, as carbon dioxide (CO2) and water or as ethanol (alcohol) and CO2. Regarding yeast, it can only be used to obtain Ethanol plus CO2 or to obtain CO2 plus water.

The path that follows from here depends on the reaction medium. The cell gets much more energy (38 molecules of ATP) by converting pyruvate into water + CO2 than by turning it into ethanol + CO2 (2 molecules of ATP). Then, whenever possible, the yeast will follow the CO2 + water path. To support this route the cell needs oxygen.  In this case, the cell obtains its energy by breathing when there is no oxygen available, the yeast has a way that allows it to gain much less energy but allows it to survive, the alcoholic fermentation, previously mentioned.

Therefore, A, B, and D answers are wrong for the reasons mentioned above.

The big bang theory is one of the most accepted theories on the origin of the universe because of scientific evidence, such as
svp [43]
1. Red-shift, which is basically the Doppler Effect, but with light. Because stars in other galaxies appear to give off red light, this shows that they are moving away from us (Earth). Red light is on the far left of the Visible Light Spectrum, so things moving away from us appear to be red, while things moving towards us appear blue (the other end of the spectrum). This suggests that the universe is expanding all the time - and therefore it might have started from a single explosion - the Big Bang.

2. Cosmic Microwave Background Radiation (CMBR) has been found by scientists to be coming from all directions in space, and is suspected to be 'left over' energy from the Big Bang.
