Answer: dna transcripted into rna
Explanation: dna is double stranded and rna in single and transcribed has to do with rna while translated is with ribosomes
This process is called transcription and it involves the conversion of DNA into RNA using the enzyme RNA polymerase. Transcription happens in three steps: initiation, elongation, and termination.
Explanation:The process mentioned in the question, where a double-stranded molecule of nucleic acid gives rise to a single-stranded molecule of nucleic acid, is best described as: DNA is transcribed into RNA. In this biological process, known as transcription, the DNA serves as the template for synthesizing RNA. This happens in three steps: initiation, elongation, and termination. During initiation, the enzyme RNA polymerase binds to the DNA strand. In elongation, RNA polymerase moves along the DNA template strand, building the RNA molecule. Finally, in termination, the RNA polymerase reaches a sequence of DNA called the termination sequence, signaling the end of RNA synthesis.

how many protons are in the nucleus of a carbon atom
Answer:
i'm pretty sure its 6 protons.
Explanation:
Carbon-14 is an isotope of the element carbon. All carbon atoms have 6 protons in their nucleus. Most carbon atoms also have 6 neutrons, giving them an atomic mass of 12.// = 6 protons + 6 neutrons\\. Carbon-14 atoms have two extra neutrons, which is a total of 8 neutrons.
A carbon atom has six protons in its nucleus, which is consistent across all its isotopes, such as carbon-12 and carbon-14. This defines its atomic number as (Option A) 6.
A carbon atom is defined by its atomic number, which is 6. This atomic number corresponds to the number of protons in the nucleus of the carbon atom. Therefore, all carbon atoms have exactly six protons in their nucleus.Carbon has several isotopes, such as carbon-12, carbon-13, and carbon-14. Despite these differences in isotopes, the number of protons remains the same across all carbon isotopes. For instance, carbon-12 (¹²C) has six protons and six neutrons, while carbon-14 (¹⁴C) has six protons but eight neutrons. The stability of these isotopes varies, with carbon-14 being naturally radioactive.Complete question as follows:

which Statement correctly describes why cells are so small? a) when cells are small the movement of food and waste can be efficiently handled by the cell membrane b) when cells are small they can adapt their shape more easily to fulfill their specific function c) when cells are small their internal parts can better support the cell membrane d) when cells are small they can easily work together to form tissue
Answer:
a) when cells are small the movement of food and waste can be efficiently handled by the cell membrane
Explanation:
Cells need to get their nutrients and waste in and out of their cell membrane every quickly. Cells are hard workers anyway! The other options also don't make much sense. The cell shape doesn't mean much to their function, and size doesn't impact shape. The cell's internal parts (mitochondria, vacuole, etc) don't support the cell membrane, they have their own functions to focus on. Cells don't work together in tissue but they can interact with each other when needed.
Answer:
The statement (a) correctly describes that why cells are so small.
Explanation:
Cells are formed of cytoplasm enveloped by a phospholipid bilayer. In the cells of plants, a supplementary cell wall also prevails. The cytoplasm accommodates various metabolic activities that need a spontaneous supply of nutrients. During the same time, metabolic wastes originate from these reactions, which are required to be eradicated. All this uptake and discard of nutrients and waste components occurs by mediation across the cell membrane via passive, active, or facilitated transport.
In the absence of any circulatory system, these cells depend entirely on the process of diffusion through the membrane. The brisk interchange of molecules can only take place if diffusion occurs over brief distances. Thus, this rate of uptake of nutrients within the cells and discarding of wastes into the external surroundings hugely relies upon the cell surface, which is restricted by the cell membrane. Thus, surface area of the cell is one of the limiting factors to monitor the rates of diffusion of these molecules. Therefore, when the cells are small, their wastes and food can be handled effectively by the cell membrane.
Explain why the jet stream looks so different in picture one and picture two. Please refer to the tutorial to answer this question. Please answer using complete sentences.
Answer:
The picture on the left is an illustration of the jet stream on the northern hemisphere during summer. In the tutorial it states, the temperature contrast between cold and warm air masses are smaller, so the jet stream is not that strong only travelling at 50-70 mph. The picture to the right is an illustration of the jet stream on the northern hemisphere during winter. In the tutorial it states the temperature contrast between cold and warm air masses are greater, so the jet stream is very strong travelling at 90-160 mph.
Explanation:
Trust me this the correct answer.
The differences in the appearance of the jet stream in two pictures can be attributed to various factors, most notably the atmospheric conditions and activities such as storms and atmospheric turbulence occurring at the time when the pictures were taken.
Explanation:The jet stream appears different in the two pictures due to the different factors influencing its visual representation in each picture. In general, jet streams are fast flowing, narrow air currents found in the atmosphere of some planets, including Earth. These streams are typically found in the troposphere or stratosphere. The path of the jet stream, which includes direction and speed, is influenced by a number of factors including the rotation of Earth on its axis and temperature differences in the Earth's atmosphere.
However, other external factors can attribute to their appearance in pictures. For instance, the presence of storms could make the flow of the jet streams appear more turbulent and change their course, while atmospheric turbulence can distort the path of light, making the jet streams seem to take different shapes. For the planets like Jupiter and Saturn mentioned in the tutorial, their differing latitudinal wind patterns and pressures also contribute to the varying appearances of their respective jet streams.

Along a mid-ocean ridge, rocks _____ moving away from the ridge.
A. become older
B. become younger
C. remain the same age
Answer:
A. become older
Explanation:
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.They technically would be old rocks because once the lava dries out it will spew out new rock, pushing away the older rock.

You go for a run and breathe heavily for an extended amount of time. How is this affecting your pH levels?
Answer:
You lose your pH levels because your heavy breathing is creating more CO2.
Explanation:
Answer:
It decreases pH
Explanation:
Alveolar hyperventilation leads to a decreased partial pressure of arterial carbon dioxide (PaCO2). The decrease in bicarbonate is accompanied by the deviation of serum pH below 7.35.
It is called Respiratory Acidosis. It´s blood pH imbalances. Muscle fatigue is associated with a rapid increase in the production of metabolic acids. Tolerance to high intensity exercise may be limited by the body's ability to dampen the decrease in intracellular (muscle) and extracellular (blood) pH, that is, the intrinsic buffer system.

SUBMIT
Answer
CORRECT ANSWER ► B
B- A periodic warming sea surface temperatures
☺☺☺
El Niño is associated with a periodic warming of sea surface temperatures, which is part of the short-term, worldwide climate event known as the El Niño-Southern Oscillation (ENSO). Hence, the correct option is B.
El Niño is a short-term, worldwide climate change event marked by the warming of the Pacific Ocean. This is an aspect of the El Niño-Southern Oscillation (ENSO) that affects weather patterns around the globe. During El Niño, typical weather patterns are disrupted, leading to significant effects such as increased rainfall in normally dry regions and diminished fish populations due to the warmer, nutrient-poor waters.
Coastal upwelling normally brings cold, nutrient-rich waters to the surface, but this is inhibited during El Niño events, deepening the thermocline and preventing the normally productive waters from supporting large fish populations. Moreover, ENSO events have a cyclical nature, typically occurring every two to seven years and can influence global temperatures and precipitation patterns.

hope this helps☆
Answer:
Option (1)
Explanation:
Sound waves are produced due to the vibration of any particular object. These waves propagate freely in air. When these sound waves change its medium from air to water, which is a denser medium, then the velocity of these waves gradually decreases. It is because, in the denser medium, the materials are compressed tightly and the speed of the sound waves in water decreases with the increasing water depth.
Thus, when the sound wave travels from air to water, it gradually slows down.

How many kilograms are in
44 pounds? 1 kg = 2.2 lbs
44 lbs = [?] kg
Answer:
20 kg
Explanation:
think of it like this:
1kg=2.2 lbs, meaning that if I want to go from lbs to kilograms, I'll have to divide by 2.2 so to go from 44 pounds to kg divide 44 by 2.2.
To convert 44 pounds to kilograms, multiply by the conversion factor of 1 kilogram = 2.2 pounds. The answer is 20 kilograms.
Explanation:To convert pounds to kilograms, you need to multiply the weight in pounds by the conversion factor of 1 kilogram = 2.2 pounds. In this case, to convert 44 pounds to kilograms, you can set up a proportion:
44 pounds = x kilograms
1 kilogram = 2.2 pounds
Cross multiplying, you get:
x = 44 pounds × 1 kilogram / 2.2 pounds
x = 20 kilograms
Therefore, there are 20 kilograms in 44 pounds.

Pyruvic acid enters the ____ and is first converted into____.
A. Mitochondria; acetyl CoA
B. Karen’s cycle; acetyl CoA
Pyruvic acid enters the Karen's cycle and is first converted into acetyl CoA.
Karen's cycle
The Karen's cycle refers to the citric acid cycle which is a cycle that releases stored energy.
Pyruvic acid is transported into the mitochondria, where it is converted into acetyl CoA via the enzyme pyruvate dehydrogenase. This step precedes the Krebs cycle, where acetyl CoA is further broken down to generate energy.
Explanation:Pyruvic acid enters the mitochondria and is first converted into acetyl CoA. This process occurs in the mitochondrial matrix where the enzyme pyruvate dehydrogenase catalyzes the conversion of pyruvate into acetyl CoA, releasing a molecule of carbon dioxide and forming NADH from NAD+ in a reaction known as oxidative decarboxylation. After its formation, acetyl CoA then enters the Krebs cycle, also known as the citric acid cycle or tricarboxylic acid (TCA) cycle, where it is metabolized to produce ATP, NADH, and FADH2.
The three-carbon pyruvate molecule generated during glycolysis moves from the cytoplasm into the mitochondrial matrix, where it is converted by the enzyme pyruvate dehydrogenase into a two-carbon acetyl Coenzyme A (acetyl CoA) molecule. This reaction is an oxidative decarboxylation reaction. It converts the three-carbon pyruvate into a two-carbon acetyl CoA molecule, releasing carbon dioxide and transferring two electrons that combine with NAD* to form NADH. Acetyl CoA enters the Krebs cycle by combining with a four-carbon molecule, oxaloacetate, to form the six-carbon molecule citrate, or citric acid, at the same time releasing the coenzyme A molecule.

where did earths water come from
Answer:
Two rocky material collision cause water formation
Explanation:
Earth is rich in water, and has been for a few billion years, but scientists are still debating just where all that life-sustaining liquid came from. At least some of it was thought to have been brought here by comets or asteroids, but that idea still falls short in explaining how so much water ended up on Earth’s surface – and deep below, as well. Now, a team of scientists at Arizona State University (ASU), led by Peter Buseck, has come up with a new proposal. The new peer-reviewed paper was published in the Journal of Geophysical Research: Planets on October 9, 2018.
The new research suggests that Earth’s water came from both rocky material, such as asteroids, and from the vast cloud of dust and gas remaining after the sun’s formation, called the solar nebula.

Earth’s ocean water is similar to that found in asteroids. That’s one reason scientists have long thought that most earthly water came from an asteroid bombardment in the days of the early solar system. The ratio of deuterium – a heavier hydrogen isotope – to normal hydrogen is a unique chemical signature in various water sources. In the case of Earth’s oceans, the deuterium-to-hydrogen ratio is close to what is found in asteroids. But, according to Steven Desch, also at ASU and one of the team members:

Considering the size of 200µm and the absence of a nucleus, the sample observed under the microscope is most likely a bacterium as bacteria typically match these characteristics.
Explanation:The sample you observed under the microscope is 200 µm in diameter and has no nucleus. Based on these observations, the sample is most likely a bacterium. Bacteria are typically around this size and lack a nucleus. In contrast, human red blood cells, which are also devoid of a nucleus, are about eight micrometers in diameter which is significantly smaller than 200 µm. Furthermore, the size of some other cellular organelles and viruses is also comparatively small. Therefore, considering the size and absence of nucleus, the most probable classification of the sample would be a bacterium.
