Weak hydrogen bonds between the nitrogenous base pairs hold the two strands of DNA together. Why are the strands held together by weak hydrogen bonds instead of covalent bonds
Answer:
Explanation:
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.

Explanation:
describe the water cycle process starting from an afternoon thunderstorm.
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.

what is an outcome of lack of oxygen?
Answer:
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.
What is 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:
16. Control group: Subject A
17. Independent (manipulated) variable: Type of powder
18. Dependent variable: Itching time
19. Explain whether the data supports the advertisement´s claims about its product. Yes, it does.
Explanation:
Control group: The control group is used to identify if there are any other factors influencing the results obtained by the treatment in the study (in this case, the new product), from the results that might be a consequence of other factors. The control group must be selected from the same population as the treatment group. Data from an experimental group are compared with the data from a control group. These two groups are identical in all aspects except for the independent variable that the researcher changes in the experimental group to observe how they affect the individuals.The experimental group is the one that receives the experimental procedure, with changes in the independent variable. There can be several experimental groups. In this case, the experimental group is subject B.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the type of powder is the independent variable. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, inching time is the dependent variable, that depends on the type of powder used. The data does support the advertisement´s claims about its product. The effect of the new product lasts 50% more than the original product. The old powder produced itching for 30 minutes, while the new product produced itching for 45min (15 more minutes, 50% more).Condensation: the ______ off of ______ in the air in the ______

6 How can you determine the origin of the oxygen released by photosynthesis?
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.

In pea plants, tall (T) is dominant to short (t). A plant with genotype Tt is crossed with a plant with type tt. What percentage of their offspring will be tall?
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
[tex] = \frac{2}{4} \times 100\% \\ = \frac{1}{2} \times 100\% \\ = 50\%[/tex]

What conditions make for a violent volcanic eruption?
OA. Magma with low gas content
OB. Magma with low viscosity
OC. Magma with high silica content
OD. Magma that can flow easily
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.
What kind of magma results in violent volcanic eruption?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.

Explain the difference between AKI and CKD
Answer:
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.

what is photosynthesis
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.
Types of photosynthesis: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.
