31. Which of the following is not true about RNA?
A) it is single stranded
B) it has 4 nitrogenous bases
C) it has a ribose sugar
D) it has thymine instead of uracil
E) it helps make proteins
Answer:
it is D. it has thymine instead of uracil
Explanation:
The incorrect statement about RNA is that it has thymine instead of uracil. In RNA, uracil is the base that pairs with adenine, not thymine.
Explanation:The statement that is not true about RNA is D) it has thymine instead of uracil. The truth is that in RNA, thymine is replaced by uracil. This means that uracil pairs with adenine in RNA, not thymine. So while DNA uses adenine, guanine, cytosine, and thymine, RNA uses adenine, guanine, cytosine, and uracil. The other statements about RNA being single-stranded, having 4 nitrogenous bases, containing ribose sugar, and helping to make proteins, are all accurate.

Which of the following scenarios would prevent a population from being in Hardy-Weinberg equilibrium?
A. The population is evolving, and natural selection is favoring one allele over another.
B. The population is stable, but younger generations of the population have a different allele frequency.
C. The population mates at specific times of the year, causing the population to fall out of equilibrium at that time of year.
D. The population will fall out of Hardy-Weinberg equilibrium if natural resources such as food are limited.
The answer is A.
the Hardy–Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
hope this helps:)
Answer:
(A) The population is evolving, and natural selection is favoring one allele over another.
Explanation:
According to Hardy-Weinberg equilibrium, the frequency (genetic variation) of population remains stable from one generation to the next generation.
The population will follow Hardy-Weinberg equilibrium if the population size is large, random mating, no natural selection , absence of mutation and gene flow.
If the population is evolving and natural selection favors an allele over another, this scenario will prevent that population to follow Hardy-Weinberg equilibrium.
Thus, the correct answer is option(A).

What are two ways that harvesting algae from the ocean may benefit human society? How might the harvest of algae negatively impact the ocean communities where the algae grows? How could this be prevented?
Answer: Hope I help!!!!!b:D
Explanation: Well, things eat the algae, and if algae is taken from an ecosystem, then it could unravel. Another thing, depending on the species, algae helps break things down like waste and clean the water!
Answer:
The harvest of algae allows them to be used for food and medicine production, as they are a source of proteins, vitamins and minerals. In addition, this harvest reduces the risks of the process called "red tide", which occurs when the algae population becomes so large in the aquatic environment, that it ends up throwing toxic elements on it, which negatively affects marine life.
The downside of harvesting algae is that harvesting can be done in a way that drastically reduces the population of algae in the aquatic environment and harms animals that have algae as their main food source. In addition, algae are responsible for much of the oxygen in the atmosphere, when harvesting it aggressively, it can impair the concentration of oxygen in the atmosphere. To avoid these problems, it is necessary to harvest the algae in a conscious and sustainable way.
Explanation:
Algae can be described as eukaryotic, autotrophic organisms that can be unicellular or multicellular, present in most rivers and oceans. Despite being very similar to plants, algae are not considered plants, but a totally different and intriguing organism. The algae make photosynthesis and are largely responsible for the oxygen available for our breathing.
Plz help asap} How is breathing related to cellular respiration? (Hint: Think about both the reactants and the products of cellular respiration.)
Answer:
Cellular respiration is related to breathing because breathing provides compulsory oxygen for the process of cellular respiration to happen and cellular respiration is a process where cells obtain energy. In time of inhalation, the oxygen molecules are necessary for cellular respiration. During the exhalation process, the CO₂ that is produced by cellular respiration leaves the body via nose or mouth. Breathing and cellular respiration are critically important because without either one of the processes, the other cannot take place
Explanation:
Answer:
Cellular respiration is not the same thing as breathing, but they are closely related. When you breathe in, you take in the When you breathe in, you take in the oxygen your cells need for cellular respiration. When you breathe out, you get rid of the carbon dioxide that your cells produce during cellular respiration.

Based on arrow movement why is the front shown in item A different from the front shown in item B?
Answer:
In item A, two air masses form a boundary; whereas, in item B, warm air rises above cold air.
Explanation:
When warm and cold air masses meet in the opposite direction, they form a boundary but warm air would still rise above the cold air, and cold air would stay below the warm air.
On the other hand, when both air masses move in the same direction, warm air would stay above the cold air and they both will move forward.

Define the term cell differentiation and describe its importance to an organism
Cellular differentiation describes how different cells perform different processes and have unique functions. There are at least 250 cells in the human body and each one plays a different role, and all of them are crucial to the body's ability to maintain homeostasis. For example, liver cells produce proteins that are important in blood clotting. If these cells are damaged, blood will not clot properly. If blood does not clot, a body cannot maintain homeostasis and the person will fall ill.

When the cell engulfs large fragments of matter, it is called _____. Select all that apply. endocytosis exocytosis pinocytosis phagocytosis
Final answer:
The correct processes when a cell engulfs large fragments of matter are called endocytosis and phagocytosis. Phagocytosis is the cellular process of engulfing solid particles, while pinocytosis takes in liquid substances. Exocytosis is the opposite process and is not a correct answer to the question.
Explanation:
When a cell engulfs large fragments of matter, the processes involved are called phagocytosis and endocytosis. Phagocytosis, a form of endocytosis, is like the cell eating. It is used by cells such as immune cells to engulf and digest large particles like invading pathogens or debris. This process involves the cell membrane surrounding the particle, and then pinching off to form a vesicle that's brought into the cell.
Another form of endocytosis is pinocytosis, also known as cell drinking, where the cell takes in fluid containing dissolved substances instead of large particles.
It's important to note that exocytosis is the opposite process, in which materials are expelled from the cell, and should not be confused with endocytosis. Therefore, the correct answers for the cell engulfs large fragments of matter are endocytosis and phagocytosis
In fruit flies, a specific gene mutation causes the wings to become malformed. These wings are called vestigial because they do not function properly. The mutated allele for vestigial wings (v) is recessive to the allele for functioning wings (V). Two fruit flies that are heterozygous for wing shape are crossed, resulting in many offspring.
You get VV, Vv, Vv, and vv

Water cycle.
Which of these stages of the water cycle were you able to observe in your model?
What is the energy source in your model and what does it represent?
Did you observe evapotranspiration in your model? If yes, where? If no, how could your have demonstrated it?
Where in your model does condensation occur more rapidly? How do u know?
Please guys, I have been stuck on this science portfolio for ever now, and I need help, I don't understand, I researched everything, my last choice is you guys! Thank you!
1. Which part of the activity simulated evaporation? Evaporation was simulated as the 'ocean' was heated by the lamp.
2. Which part simulated condensation? Condensation occurred as the water vapor from the ocean cooled on the lid of the shoe box near the petri dish of ice.
3. Which part simulated precipitation? The drops of water falling from the lid of the shoe box simulated precipitation.
4. What is the energy source and what does it represent? The energy source was the lamp, which represented the sun.
5. What elements of the water cycle are not represented? Transpiration, infiltration, sublimation, and percolation were not represented.
6. How could we demonstrate transpiration in this activity? We could demonstrate transpiration by adding live plants to the shoe box.
7. Would condensation occur in the box without the ice? Why or why not? Condensation might occur over the mountains but not as quickly. The ice provided a greater temperature difference, forcing the vapor to condense.
8. After observing this activity, explain why water is considered a renewable resource. Water is continually recycled through the various parts of the water cycle.
9. The system you observed/constructed is a model of the way the actual water cycle works. Why might scientists use a model like this in their research into the water cycle in the real world? Can you think of any reason that using such models might be a problem?
In a model of the water cycle, you're able to observe evaporation, condensation, and precipitation, with an energy source like light representing the Sun. Evapotranspiration can be demonstrated with a plant, and condensation occurs more rapidly in cooler areas.
Explanation:From your question, I infer that you've created a model of the water cycle. Typically, in a water cycle model, you can observe stages such as evaporation, condensation, and precipitation. Your energy source in the model could be light (representing the Sun), which fuels the evaporation process.
Evapotranspiration, which combines the processes of evaporation and transpiration (water loss from plants), might not be observable unless you incorporated living plants in your model. You could introduce a small plant in your model to demonstrate this process.
Condensation, the process by which water vapor turns back into liquid water, often happens more rapidly in cooler areas in your model. You could identify this by observing where droplets form the fastest.

Which of the following makes fungal pathogens more difficult to treat with medication?
A. They are eukaryotic cells that have their own cell membranes.
B. They aren't living, so can't be treated with antibiotics.
C. They prevent the body from digesting medications.
D. They are often fast-acting infections that don't provide time for medication.
The answer would be A.
Fungi are harder to treat than bacteria bc they are eukaryotes and bacteria are prokaryotes. Bacteria have a cell wall made up of peptidoglycan and most antibiotics target that in order to destroy them and get rid of the infection.
Hope this helps:)
Answer:
The correct answer would be option A.
Explanation:
Fungal infections are commonly very tough to treat because, not like bacteria cells, fungi are eukaryotes and more close to the animals. Many fungal diseases are superficial; that is, they occur on the animal's skin.
Antibiotics only attack and kill prokaryotes, whereas medications that kill or harm fungi cells also harm the eukaryotic animal host because both have a similar type of cell membrane.
Thus, the correct answer is option A.
