Answers
Answer: Electrons flow because of electrical attraction and repulsion.
Explanation:
-Electrons build up in the wire and create a charge. This is false, electrons do not "build up" like water would in a pipe.
-Protons are pushed along by electric forces. This is false, protons do not generate elecricity.
-Electrons flow because of electrical attraction and repulsion. This is true. Electrons flow by attracting and repulsing other electrons.
-Atoms move because of heat. This is partially true, but does not explain how electric current moves in a wire.
Answer:C. Electrons flow because of electrical attraction and repulsion.

Answers
Answer:
A carnivore is any animal that only eats meat. Such as a lion or a snake.
Explanation:
Carnivores are animals that eat other animals, and examples include lions, polar bears, hawks, snakes, and spiders. They can be obligate carnivores, needing only meat, or facultative carnivores, which can also eat plants.
Here are some examples of carnivores:
Lions - These wild cats are obligate carnivores, meaning they rely entirely on meat for their nutrients.Polar Bears - Primarily consume seals and other marine animals.Hawks - Birds of prey that hunt and feed on smaller animals like rodents and other birds.Snakes - Many species of snakes are carnivorous, feeding on prey such as rodents, birds, and amphibians.Sharks - These marine predators feed on fish and marine mammals.Spiders - Invertebrate carnivores that capture and eat insects and other small arthropods.
How does our sun compare to other stars in terms of surface temperature, apparent magnitude, absolute magnitude, and size?
(1 point)
A. Our sun reigns supreme! It is the biggest, hottest, brightest star in the universe. Rock on, Mr. Sun!
Answers
Answer:Plz mark Brainliest
Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one. Our Sun is 864,000 miles in diameter and 10,000 degrees Fahrenheit on the surface.
Explanation:
I learned about it last year
Compared to other stars in the universe, the Sun is a uniquely shaped star. Its surface is about 5,500 °C hot.
As seen from Earth, the apparent magnitude or brightness of the Sun is relatively high, approximately −26.7, making it relatively bright. However, from our vantage point, some stars appear to be brighter. The absolute magnitude of the Sun, which measures its intrinsic brightness, is about +4.8, meaning that if viewed from a normal distance, it would appear fainter than many other stars.
The Sun is a typical sized object, with a diameter of about 1.4 million kilometres. Despite the fact that it is important to humanity, the Sun is not the biggest, hottest, or brightest star in the universe.

Why is Dr. Tumpey's radical approach to "virus engineering" controversial? What are the potential benefits of this approach?
Answers
Explanation:
It is based on the principle of continuous improvement. The standard enables companies to define what a quality product should be and how it should meet customer needs.
Because Dr. Tumpey's approach requires the construction of artificial yet functional viruses to study them. This can be beneficial because it allows future pandemics to be identified and tackled before they happen.
We can arrive at this answer because:
Dr. Tumpey believes that virus engineering should be used to further the study of potentially pathogenic viruses.In this case, he states that viruses must be constructed artificially, but keep them functional, so that all their characteristics, pathogenicity, and future evolutions can be studied in depth.This is controversial because many fear that these artificial viruses could be used as biological weapons and promote mass destruction.However, we cannot fail to state that this can be a beneficial approach to prevent new pandemics from happening, as the study of possible evolution and pathogenicity of these viruses can create controls that prevent them from spreading and creating diseases all over the world.

when three molecules of carbon dioxide react with 3 molecules of RuBP during the carbon cycle six molecules of the sugar g3p are produced. one g3p molecule exits the Calvin cycle during phase 2. what happens to the other five g3p molecules?
I need help plz!!!
Answers
Answer:
The other five molecules of G3P are used to regenerate 3 molecules of Ribulose-1,5-biphosphate.
Explanation:
Calvin cycle, also called light independent stage of photosynthesis. It is the stage where the NADPH and ATP produced during the light stage is used to synthesize glucose.
Calvin cycle occurs in three main stages viz: Carbon fixation, Reduction and Regeneration.
In the carbon fixation, three (3) molecules of CO2 reacts with 3 molecules of CO2 acceptor called Ribulose-1,5-biphosphate molecule catalyzed by RUBISCO to form two molecules of 3-phosphoglycerate (PGA)
In reduction stage, PGA is reduced by NADPH and phosphorylated by ATP to form 6 molecules of Glyceraldehyde-3-phosphate (G3P). As stated in the question, 1 molecule of G3P exits the Calvin cycle to be used to form glucose while the other 5 molecules proceeds in the cycle.
In the third stage called Regeneration stage, the first (5) molecules of G3P are rearranged in a series of reactions into 3 molecules of the five-carbon CO2 acceptor called Ribulose-1,5-biphosphate (RUBP).
explain how the molecular structure of water gives it properties that make it useful to humans
Answers
Answer:
Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
Final answer:
Water's molecular structure, characterized by a bent shape and polar nature, leads to hydrogen bonding. These bonds contribute to water's unique properties such as being a good solvent, having high boiling and melting points, and being important for biological processes. Understanding water's structure provides insight into its crucial role in sustaining life.
Explanation:
The molecular structure of water contributes to various properties that are useful to humans. The H2O molecule has a bent shape, with one oxygen atom covalently bonded to two hydrogen atoms. This geometry and the resulting polar nature of water molecules lead to hydrogen bonding, a strong type of intermolecular force. Hydrogen bonds allow water molecules to stick to each other, which explains why water has a higher boiling and melting point compared to other molecules of similar size.
Additionally, this structure enables water to dissolve a wide range of polar substances, making it an excellent solvent for biological processes and industrial applications. Water's cohesive and adhesive properties are also attributed to hydrogen bonding, allowing for phenomena such as capillary action, which is crucial for plant hydration. Furthermore, the slight dissociation of water molecules into ions facilitates the generation of pH, a key aspect in many chemical reactions, particularly those within living organisms.
Despite being a simple molecule, water's properties have a profound impact on life on Earth. Scientists use quantum theory and other advanced calculations to investigate the electron density around water molecules and fully explain its unique properties. All these features underscore the significance of water's structure, which is central to its diverse functions and importance.

The Seven Sisters are seven stars located more than 400 light-years away in the Taurus constellation and they can be seen here with Venus and another constellation, Orion. Why do these stars seem so small compared to our Sun, also a star?
A) Our Sun is much larger than any of the Seven Sisters.
B) Our Sun is much closer to Earth than the Seven Sisters.
C) The Seven Sisters are ancient stars; the Sun is a young star.
D) Stars found in constellations are much older and smaller than any other
Answers
Answer:
Option B
Explanation:
The seven stars are bigger in size as compared to the size of the sun. Also, these stars are more luminous as compared to sun. However, these stars appear small in size in comparison to sun because of their distance from earth. The larger is the distance, the dimmer is the star. Sun is at a distance of 0.0000158 Light years from Earth while the nearest star of the seven sister i.e Alpha Centauri is 4.37 light years away.
Hence, option B is correct
The stars of the Seven Sisters look smaller than the Sun because they are far more distant from Earth, while the Sun is relatively close.
The Seven Sisters, or the Pleiades, appear small compared to our Sun because of the immense distance separating us from them. Although some of the stars in the Pleiades might be larger than the Sun in terms of light-giving power or actual size, they are over 400 light-years away. In contrast, our Sun is much closer to Earth, at about 93 million miles away, making it appear significantly larger in the sky.
The correct answer to why the Seven Sisters seem so small compared to our Sun, also a star, is B) Our Sun is much closer to Earth than the Seven Sisters.

What does it mean when a trait is independent from another trait? Give one example.
Answers
Answer:
It means one trait does not influence the expression of the other. Example is given in the explanation section.
Explanation:
A trait is the phenotypic characteristics an organism possesses. It is determined and controlled by genes. According to Mendel, an organism receives two forms of every gene called ALLELE. Each allele of a gene encodes a different trait.
Mendel, in his law of independent assortment stated that the inheritance of a trait encoded by the alleles of one gene does not influence the inheritance of another trait encoded by the alleles of another gene. A trait is said to be independent of another if it doesn't influence the expression of the other trait.
An example is the seed colour and seed shape trait in a plant. The seed colour trait is encoded by a certain gene and its expression and inheritance is independent of the seed shape trait encoded by another gene.
Which two statements describe the advantages of genetic engineering
Answers
Answer:
B and D
Explanation:
Genetic engineering allows for the creation of crops with enhanced nutritional profiles and herbicide tolerance, improving food security and agriculture sustainability. Biopharmaceuticals are another advantage, producing medical proteins in plants. Genetic modifications can be precisely controlled, leading to potentially safer GMO foods.
The advantages of genetic engineering include the ability to produce plants with higher nutritional value and the development of crops that can tolerate herbicides. This not only helps in addressing nutritional deficiencies but also allows for more efficient farming practices, as farmers can manage weeds without harming their crops. Additionally, genetic engineering has led to biopharmaceuticals, where beneficial proteins are produced by genetically modified plants, offering new avenues in medicine.
Another significant benefit of genetic engineering in agriculture is increased food security. By developing crops that require less water, resist pests, and grow in harsh environments, scientists are creating solutions for producing food more sustainably. This is particularly important as the global population grows and the demand for food increases. Furthermore, the precise nature of genetic engineering allows for a more controlled modification of plants compared to traditional crossbreeding, potentially leading to safer GMO foods.
