Answer:

My experiment showed that energy production, or respiration, occurred in yeast even when little oxygen was present. During exercise, the lungs must work hard to take in oxygen, which then circulates to the body parts that need it. The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.

Explanation: from plato, so change it a bit.

The experiment showed that energy production, or respiration, occurred in yeast even when little oxygen was present. During exercise, the lungs must work hard to take in oxygen, which then circulates to the body parts that need it. The ability to preform anaerobic respiration for short periods of time allows humans to sustain activity, even when oxygen is limited in the body.

Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.

In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. Molecular oxygen is an excellent electron acceptor. Anaerobes instead use less-oxidizing substances such as nitrate (NO−3), fumarate (C4H 2O2−4), sulfate (SO2−4), or elemental sulfur (S). These terminal electron acceptors have smaller reduction potentials than O2. Less energy per oxidized molecule is released. Therefore, anaerobic respiration is less efficient than aerobic.

Sunlight

Explanation:

I just got it wrong because of the wacko below or above me gave me the wrong answer

Algae possess chlorophyll in their cells. They use carbon dioxide in a manner that is analogous to how we use food. Thus, option B is correct.

By converting light energy to chemical energy through the process of photosynthesis, carbon dioxide and water are transformed into organic molecules.

Nearly all algae engage in the process, and in fact, much of what is currently known about photosynthesis was first uncovered through research on the green alga Chlorella.

Like other plants, algae benefit from sunlight, therefore denying them of it will limit or even completely stop their growth. For several days, completely shading the tank or aquarium from light is essential.

Therefore,  algae require sunshine because algae can photosynthesize, or use sunlight to change carbon dioxide into biological material.

The safety an​d effectiveness of vaccines​ are under constant study. Because vaccines are designed to be given routinely during well-child care visits, they must be extraordinarily safe. Safety testing begins as soon as a new vaccine is contemplated, continues until it is licensed, and is monitored indefinitely after licensure.

Explanation:

Answer:

well

Explanation:

Before a vaccine is ever recommended for use, it’s tested in labs. This process can take several years. FDA uses the information from these tests to decide whether to test the vaccine with people.

During a clinical trial, a vaccine is tested on people who volunteer to get vaccinated. Clinical trials usually start with 20 to 100 volunteers, but eventually include thousands of volunteers. These tests can take several years and answer important questions like:

Explanation:

Speeds can be faster for small-scale convection occurring in low-viscosity regions beneath the lithosphere, and slower in the lowermost mantle where viscosities are larger. A single shallow convection cycle takes on the order of 50 million years, though deeper convection can be closer to 200 million years.

Explanation: In a ecosystem, if you have different animals or organisms, it give them a better chance of survival, reason being that they can choose to eat whatever animal or organism they want because there is lots of animals to choose from the ecosystem. Basically the more diversity you have, the better chance you will survive, and the less diversity you have, the less chance of survival.

Answer:

D The processes of transcription and translation, including the genetic code, are the same in the beetle as in nearly all other organisms.

Explanation:

Transcription is the cellular process where a specific DNA fragment called 'gene' is used as a template to create a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is then used to synthesize a polypeptide chain (i.e., a protein) in the ribosomes. In eukaryotic organisms such as, in this case, beetles, both transcription and translation are essentially the same processes, and the genetic code used in the protein synthesis is also the same. The difference between beetles is the variation among DNA nucleotide sequences (genomes) which are used as templates to synthesize mRNAs, thereby their final products (proteins) are also different.

1) Reflection is when a ray hits something reflective then bounces back. For example, light reflects off a mirror, which is why you can see yourself in a mirror.

2) Wavelength measures the size of a wave. It is measured from the crest or trough of one wave to the crest or trough of another.

3) Refraction occurs when waves go through different mediums at different speeds. This is why a straw looks bent when in water.

4) Frequency is a way of measuring the speed of a wave. It shows how many waves pass every unit of time.

5) Absorption means that all of the waves were absorbed into the medium and none of them passed through.

Answer:

The air in New York moves to the north.  

Explanation:

At a global level, it occurs unequal warming of the atmosphere, which depends on many factors and varies with latitude. These temperature differences occur because solar radiation reaches the earth differently at different latitudes degrees. The result is the formation of convective cells of atmospheric air circulation: Hardley cell, Ferrel cell, and Polar cell.    

The term convective cell refers to air getting warm, expanding, getting less dense, and ascending. During ascension, it gets colder because of the change in high, contracting, becoming thicker. Finally, it descends.

In each hemisphere, warm air ascends at the equator and approximately at 60º latitude. Cold air descends at approximately 30º latitude and the poles. These air masses circulation generates superficial winds that blow toward the equator between 0º-30º, and toward the poles between 30º-60º lat.  

Ferrel cell occurs between 30º and 60º latitude. At 30º lat, the cold air coming from the north in the tropopause meets the cold air coming from 0º, and both descend to lower altitudes due to its density and low temperature. When these air masses reach the ground, they diverge.  One part goes to 0º lat, while the other part goes forward to the north.  As it moves north, it gets warmer for being at lower altitudes. At 60º, this warm air coming from the 30º meets the polar air coming from 90º, and as it is warmer it ascends again. When it ascends to the tropopause, it is pushed by new air and moves to the south again. While doing so, it loses heat and becomes denser, descending again at 30º.  And so the cycle starts all over again. New York is located at 40º latitude approximately, so air goes forward to the north pole near the ground, but at 60º it elevates again. New York is then affected by the Ferrel cell.        

In the attached image you will find the three cells, circulating in different directions.  

Hydrosphere and Atmosphere: The erosion of rocks, a major part of the rock cycle and change in the geosphere over time, turns rock into sediment and then, sometimes, to sedimentary rock. ... Different combinations of sedimentary rocks form in environments with different climate conditions.

Answer:

Explanation:

Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
