What happens in the G2 phase of the cell cycle?

Answer:

C) reduced because electrons are gained which produces reduced water

Explanation:

The electron transport chain (ETC) involves a series of chemical reaction based on the reduction and oxidation of molecules. According to the question, the electrons that leave the chain combine with a final electron acceptor called Oxygen. This reaction is a reduction reaction because oxygen gains electrons.

The gaining of electrons by Oxygen reduces it to water (H2O). Hence, water is said to be reduced because electrons are gained by oxygen to produce a reduced form, called water.

Answer:

B. Ordered

Explanation:

we found complete question that is: A student measures the range of sound frequencies that the human ear can hear by playing sounds for volunteers between 10 and 30,000 Hertz and asking them to raise their hand if they were able to hear it. What type of variable is the independent variable in this experiment?

A. Categoric , B. Ordered ,  C. Continuous , D. Discrete

solution

Volunteers between 10 and 30,000 Hz ask the human ear to raise their hand when the student is measuring the range of sound frequency and if they can hear it; This requires consistent answers from the experiment participants on whether or not they can hear the sound. Therefore, the category can be classified under the ordinal category ordered.

as eg. Highest Education Level has variable Elementary School, High School, many College and College Graduate

Answer:

Adhesion

Explanation:

Technically, you need cohesion(water sticking to itself through attraction of hydrogen bonds) to get adhesion(water sticking to other surfaces through attraction of hydrogen bonds). They are rather intertwined. But for this basic answer, it is adhesion.

Answer:

B. They are considered stable over a lifetime

Explanation:

The only statement that is not true concerning the definition of life in general is that "They are stable over time." This can be proven in the early years of earth's life wherein different microorganism and macroorganism lives. Over time, they evolved into another species that is most suitable to the kind of envionment the earth is evolving.

It flows from high pressure to low pressure as air is made up of gases and gases move according to the process of diffusion.

It moves from lower density to higher density as pressure is inverse to density. As density is not what makes the air move it is pressure.

Explanation:

The first step a geologist would take in order to compare rock layers at distant locations is to Assign a date to the rock layers.

That is, they a relative age to a layer of rock at one point and then give the same age to matching layers at another point. By studying and identifying index fossils, geologists are able to match the rock layers.

Cheers!

The first step that geologists must do to compare rock layers at distant locations is to identify index fossils in one or more layers at one location. This is further explained below.

Generally, rock layers is simply defined as Strata, another name for rock layers, and stratigraphy is the science of strata.it shows rock formation over time.

In conclusion, Rock layers are key to geological research of the Environment.

Answer:

it acts as products/reactants it acts to stablize the temperature

Explanation:

Dry heat sterilization is very useful to be used in materials that cannot come into contact with forms of heat sterilization such as steam. It is also widely used for objects that cannot come into contact with very high temperatures.

This type of sterilization is done by buckling, incineration, intra-red rays or hot air oven. In any case, it is important that the water is completely removed, both from the object and from the sterilization vehicle. This is because water is easily used by possible microorganisms to stabilize the temperature in their bodies, which can cause sterilization failures.

Answer:

The paramecium body.

Explanation:

1. The objective lenses on a compound light microscope doess have powers that start of as smallest to highest power, 4x, 10x, and 40x on the maximum power setting. This means that the sample can be magnified either, 40x, 100x or 400x.

At 40x magnification Stella will see organism 5mm.

At 100x magnification Stella will be able to see organism 2mm.

At 400x magnification Stella will be able to see organism more closely, 0.45mm, or 450 microns.

2. Paramecia are shoe shape or molded and almost transparent and shrouded in a defensive pellicle.

Pellicle capacities like skin and shields them from the components. For movement they have cilia.

Answer:

At 40x, Stella could see the cells, but they looked really small. At 100x, Stella was able to see the cells to the point where she could see most of them up close. At 400x, Stella could see the cells one by one close enough. Some of the cells are shoe-shaped, which is one of the characteristics of paramecium. The brown at 400x next to the orange is the one that mostly looks like a shoe.

The correct answer is A. Two populations of finches that cannot produce viable offspring

Explanation:

Reproductive isolation is a biological and evolutionary phenomenon that prevents two species from successfully reproducing, this means they cannot produce offspring or the offspring is not fertile, even if these species had a common ancestor. Additionally, as a result of reproductive isolation, each species keeps its genes and features. This phenomenon is best exemplified in "Two populations of finches that cannot produce viable offspring " because this refer to the barriers for different species to reproduce or produce viable offspring, which is the focus of reproductive isolation.

Answer:

A.) for souvenirs

Explanation:

Tourists are interested in mining corals mainly to get souvenirs, since corals are known to be pretty and would be a "good" souvenir because of that.

Tourists would not be interested in mining corals to build roads, get protection, or get bone grafts because tourists are just interested in visiting a place and getting souvenirs from it.

Coral mining is the removal of coral reefs through various methods. The tourists mines coral to keep or gift them as souvenirs. Thus, option A is correct.

Corals are the hard aquatic invertebrates that belong to the phylum Cnidaria and are found in the form of colonies and as individual polyps. They together make a coral reef that is an important part of the ecosystem.

Though the polyps are softer they secrets a harder covering of shells made of calcium carbonate that gives an appearance of a hard skeleton or rock. The mining of corals has been seen as having a negative impact on the ecosystem as protects from erosion and is a source of medicines and home to various marine organisms.

The corals have been mined by the tourist to keep them as souvenirs. It is seen that they are pretty and is good to keep. They act as tokens of remembrance for the tourist as they have visited the place and are beautiful.

Therefore, option A. the tourists keep coral as souvenirs.

Anaerobic respiration in yeast (Saccharomyces cervisae) is also called alcoholic fermentation

C6H12O6--->2C2H5O+2CO2

Ethanol can be used as a disinfectant.

Ethanol can also be present in beverages.

Anaerobic respiration in yeast.

Anaerobic respiration is economically important - many of our foods are produced by microorganisms respiring anaerobically. Yeast is used to making alcoholic drinks. When yeast cells are reproducing rapidly during beer or wine production, the oxygen is used up.

Another advantage of anaerobic respiration is its speed. It produces ATP very quickly. For example, it lets your muscles get the energy they need for short bursts of intense activity (see figure below). Aerobic respiration, on the other hand, produces ATP more slowly.

Anaerobic respiration in yeast

The yeast switches to anaerobic respiration. Ethanol and carbon dioxide are produced.
