Dont mind the answer I picked

Answer: B

Explanation:

Magma with low viscosity

Magma that has high content of silica will lead to a violent volcanic eruption. Thus, the correct answer is option C.

Magma that has a high content of silica will have high viscosity. This is due to the bond formation between silicon and oxygen, forming a Si-O tetrahedron.

These tetrahedra combine with each other and result in polymerization which increases the resistance of the liquid to flow. This type of thick magma does not flow easily and will result in an explosive eruption.

High amount of silica causes a lot of gas to be trapped in the volcano.  High-viscosity magma does not allow for the exsolution of gas bubbles.

Thus, the gas bubbles will be trapped inside and increase pressure on the magma column to explode. The trapped gas thus provides the driving force for the explosion.

Thus, the correct answer is option C.

Blood carries oxygen to the cells throughout your body to keep them healthy. Explanation:

Hypoxemia can cause mild problems such as headaches and shortness of breath. In severe cases, it can interfere with heart and brain function. Hypoxemia that causes low oxygen levels in your body's tissues is called hypoxia.

The outcome of lack of oxygen To maintain your body's cells healthy, blood provides oxygen to every cell.

The smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The substances that enter and leave the cell are governed by the cell membrane, which encloses the cell.

There are two different types of cells: prokaryotic cells, which lack a nucleus but still have a nucleoid area, and eukaryotic cells, which have a nucleus. Eukaryotes can either be single-celled or multicellular, in contrast to prokaryotes, which are single-celled organisms.

From bacteria to humans, cells give all living things their structure and functionality. They are regarded as the tiniest form of life by scientists.

Answer:

because all green plants release oxygen and non- green plants do not release oxygen.

Explanation: One of the first uses of an isotopic tracer in biology was in the determination of the source of the oxygen produced by photosynthesis. Using a heavy isotope of oxygen, 18O, to label one of the two reactants in the photosynthetic process, Samuel Ruben and collegues at UC Berkeley were able to determine that the oxygen gas came not from carbon dioxide, but water.

Considering the given descriptions of metabolic reactions, the correct terms described are:

1.  photosynthesis.

2. photosynthesis

3. citric acid cycle.

4. respiration.

5. pigments.

6. chlorophyll.

7. thylakoids.

8. electron transport chain.

9. fermentation.

10. Adenosine triphosphate

11. Aerobic reactions

Photosynthesis is one of the many chemical reactions that occur in living organisms.

Photosynthesis is the process by which living organisms known as plants use the energy of sunlight to convert carbon dioxide and water into chemical energy stored in foods.

These chemical reactions are known as metabolic reactions and are essential for the growth and development of the living organism.

Considering the given descriptions of metabolic reactions:

Photosynthesis is the process some organisms are able to use by which they convert light energy to chemical energy. It is the main method by which photosynthesizing organisms use for carbon dioxide fixation to produce food nutrients.

The green pigment that absorbs light and provides energy for photosynthesis is chlorophyll.

Pigments are substances that absorb some wavelengths of light and reflect others, giving something its color.

Chlorophyll is found within chloroplasts. Thylakoids are disc-shaped sacs in chloroplasts where photosynthesis takes place.

Through the process of respiration, cells produce energy from carbohydrates. In living organisms such as man, the citric acid cycle is a set of chemical reactions that break down pyruvate, producing electron carriers for an electron transport chain that powers ATP production.

Adenosine triphosphate, ATP, is a substance that stores and releases energy for most cell processes.

The electron transport chain refers to a series of molecules in the inner membranes of chloroplasts and mitochondria down which excited electrons pass, releasing energy for ATP production.

ATP production can occur under aerobic or anaerobic conditions.

Aerobic reactions are processes that require oxygen​ while anaerobic reactions do not require oxygen.

The process by which NAD is recycled under anaerobic conditions in order to continue the breakdown of carbohydrates to supply energy for producing ATP is called fermentation.

Complete question:

The San Marcos salamander, Eurycea nana, is a light reddish-brown

translucent salamander about 2-5 cm in length. E. nana is found only in

Spring Lake and a portion of the San Marcos River.

Which human activity would most likely decrease the ability of the

salamanders to survive?

The addition of a new food source into the river that limits competition for

resources

Tourism that helps fund the educational programs related to river ecosystem

conservation

Public transportation that reduces the number of automobiles that contribute to

pollution runoff into the river

Increasing water consumption that decreases the flow of clean water from the

springs that feed the river

Answer:

Increasing water consumption that decreases the flow of clean water from the springs that feed the river

Explanation:

In this question we are required to state the human activity that may likely cause the reduction in the survival rate of the salamander.

the first three options in the question are not the answer to this question. this is because options 1,2,3 would have positive impacts on the Salamander. these positive impacts would increase the ability of the salamander to survive and not decrease it as the question says.

the correct answer is the last option. that is the 4th option. because it has to do with decreasing the amount of water that flows in to the Salamanders habitat by human activities. if humans increase water consumption, then the flow of clean water would reduce. This would then have a negative effect on the Salamander.

Answer:

Isotonic: there would be no net flow of water, the cell will stay stable

Hypotonic: the cell will fill up with water and burst

Hypertonic: The cell will shrink because it loses water

Explanation:

Mechanical waves are waves that require a material medium for propagation e.g sound waves and waves on a spiral spring.

Electromagnetic waves do not require a material medium for propagation. They can travel through space.

The light and heat of the sun are far away in outer space yet they reach us on earth. There is no intervening medium between the earth and the sun that conducts its rays to the earth. As a result of this, we can conclude that the rays from the sun are electromagnetic waves.

Answer:

50%

Explanation:

Draw a Punnet square to determine the percentage of offspring that are tall.

The green and blue highlighted columns and rows represents the genotype of the parents. To fill in the genotype of the offspring, write down the letter (T/t) of the parent allele from that row and column the offspring belongs to. By convention, the T is written before t. (The genotype of a tall offspring is written as Tt not tT)

Since the T allele is dominant, as long as the offspring has one T, the offspring is tall. The t allele is recessive, thus two ts (tt) is needed for the short trait to be expressed.

From the Punnet square, the result is 2 offsprings that are tall and 2 offsprings that are short.

Required percentage

Hydrogen bonding is usually occur wen interaction with hydrogen atoms occur.

Hydrogen bonds joins DNA polymers because an hydrogen atom occur on on one base which is called hydrogen bond donors and another oxygen or nitrogen atoms on the base across from it which is called hydrogen bond acceptors.

Adenine “A” a purine and Thymine “T” a pyrimidine each have a donor and one acceptor, whereas Cytosine “C” a pyrimidine has one donor and two acceptors, and Guanine “G” a purine has one acceptor and two donors.

This atoms allows for hydrogen bond between them that gives them structure of DNA molecule.

A nucleotides is hydrogen bonded to T nucleotides while C nucleotides is hydrogen bonded to G nucleotide this is called complementary base pairing.

Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy. Here, we describe the general principles of photosynthesis and highlight how scientists are studying this natural process to help develop clean fuels and sources of renewable energy. 

There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria. 

During oxygenic photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), to produce carbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water becomes "oxidized," or loses electrons. Ultimately, oxygen is produced along with carbohydrates.

Explanation:

photosynthesis the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

Acute kidney injury (previously called acute kidney failure) is the sudden loss of kidney function, usually as a result of illness, drugs or injury. Acute kidney injury is commonly reversible. Chronic kidney disease (CKD) will progress to chronic kidney failure with time.

Explanation:

Answer:

AKI is reversible (for the most part) where CKD is not

Explanation:

AKI develops very suddenly. It is normally caused by an acute renal insult and encompasses a spectrum of renal impairment from minor changes in markers of renal function. Managing AKI includes; identifying and treating the underlying case and doing your best to minimize as many complications as possible.

CKD develops over time, normally taking a few months to years for it to show itself. It normally comes from having diabetes and hypertension. The disease itself is, more often than not, discovered when going through screening for other, unrelated, diseases. You can slow down the progress of renal failure but you can't treat it. CKD will eventually lead to permanent dialysis or the patient needing a kidney transplant.

Answer:

B because they are mutated and they are dividing faster than group A

Explanation:

Answer:

Most thunderstorms form by a cycle that has three stages: the cumulus stage, mature stage, and dissipating stage.

Cumulus Stage

The sun heats the Earth's surface during the day. The heat on the surface and warms the air around it. Since warm air is lighter than cool air, it starts to rise (known as an updraft). If the air is moist, then the warm air condenses into a cumulus cloud. The cloud will continue to grow as long as warm air below it continues to rise.

Mature Stage

When the cumulus cloud becomes very large, the water in it becomes large and heavy. Raindrops start to fall through the cloud when the rising air can no longer hold them up. Meanwhile, cool dry air starts to enter the cloud. Because cool air is heavier than warm air, it starts to descend in the cloud (known as a downdraft). The downdraft pulls the heavy water downward, making rain.

This cloud has become a cumulonimbus cloud because it has an updraft, a downdraft, and rain. Thunder and lightning start to occur, as well as heavy rain. The cumulonimbus is now a thunderstorm cell.

Dissipating Stage

After about 30 minutes, the thunderstorm begins to dissipate. This occurs when the downdrafts in the cloud begins to dominate over the updraft. Since warm moist air can no longer rise, cloud droplets can no longer form. The storm dies out with light rain as the cloud disappears from bottom to top.

The whole process takes about one hour for an ordinary thunderstorm. Supercell thunderstorms are much larger, more powerful, and last for several hours.
