Get opinions from your fellow associates which help in increase your knowledge on a topic or a given situation. Thus option B is correct.
what is general knowledge ?
To get information, understanding, or skill that from experience or education or some one else is called as knowledge.
General knowledge is a broad field of gathering valuable information related to social interests, culture, civilization, community, or nation gathered from a various media platforms.
It is not under a specialized information on a specific topic; it is knowledge about every aspect of human life like current affairs, fashion, family, health, and the arts and sciences.
To gain general knowledge, it takes huge time and effort, intelligence, problem-solving, confidence, and open mindedness etc. It helps with personal growth, good citizenship, and a stronger society.

So if the Moon's shadow is falling on the Earth during a solar eclipse, what phase of the moon must it be? (The moon is between the Earth and Sun.)
Answer:
New moon
Explanation:
A solar eclipse can only occur during New Moon (when the entire moon is covered in darkness and not visible from the earth's surface.) A total solar eclipse can be seen within the moon's dark inner shadow (called the umbra.) A partial solar eclipse can be observed within the earth's lighter outer shadow (called the penumbra).
What are greenhouse gasses? How does carbon dioxide enter the atmosphere? (Site 1)
Answer:
1. Greenhouse gases are compounds that are able to trap heat in the atmosphere, keeping the Earth's surface warmer than it would be if they were not present. These gases are mainly carbon dioxide; metahne, nitrous oxide, and flourinated gases.
2. Carbon dioxide enters the atmosphere from animals and plants through the process of respiration and the burning of fossil fuels from industries.
Answer:
The greenhouse effect is a natural phenomenon, which, helps maintain the relatively stable, livable, range of temperatures that we find on earth. To better understand how this phenomenon works, scientists have used the analogy of the greenhouse. In a greenhouse, the glass (the atmosphere) allows the radiant energy (light) of the sun to enter. As the radiant energy strikes various plants, gases, and objects in the greenhouse, they heat up. Their heat is then released back into the air of the greenhouse as infrared radiation (heat). This infrared radiation cannot travel through the glass and remains inside the greenhouse, increasing the temperature inside the greenhouse. Temperatures can be controlled, or kept in balance, by allowing some of the heat to remain inside and some to be vented to the outside. Under normal conditions, the earth's atmosphere works in a similar manner. Solar radiation enters the atmosphere and heats up the air molecules, the surface of the earth, buildings, plants, and other objects. These objects in turn, radiate infrared radiation back out into the atmosphere, where some of this radiation is absorbed by the greenhouse gases, and some is radiated out into space. As some of the heat stays in the atmosphere and some escapes into spaces, a balance is maintained allowing our planet to have a relatively stable range of temperatures. Scientists believe that as the greenhouse gases become more abundant in the atmosphere, due mainly to the burning of fossil fuels, they retain more and more infrared radiation, allowing less and less to escape into space, tipping the balance toward heating up the atmosphere, resulting in a changing and warmer climate, planet-wide. This is the accelerated greenhouse effect.

Which is the most likely reason that stem cell research is controversial?
Stem cell research could lead to the development of human clones.
Many people assume that all human stem cells come from embryos.
Research by using stem cells results in high-priced treatments for disease.
Information that is obtained from stem cell research is considered unreliable.
Answer
Many people assume that all human stem cells come from embryos.
Explanation:
Not all stem cells are embryonic stem cells. In fact, a lot of stem cell type procedures come from stem cells in bone marrow. The controversy behind embryonic stem cells is that they come from aborted babies, which many don't agree with.

Which term is correct for one female arctic fox? biome species ecosystem organism
Answer:
D.) Organism
Explanation:
On the basis of biological organization, one female arctic fox will be considered as an organism.
Biological organization refers to a hierarchy starts from simplest biological structure to complex biological structures that define life, such as from atoms to biosphere.
So, biome is the community of animals and plants having common characteristics according to the environment; species is also a group of living organism sharing similar genes; ecosystem include different groups with the physical (abiotic) environment and organism is the basic living system,that include at least one cell.
So, one female arctic fox will be termed as an organism and the correct option is D.
Answer:
D.) Organism

Scientists often work together with other scientists. If you were working in a laboratory working together in a way that is effective, and help make sure that people got fair credit for their work? What is needed for people to work together in an effective way?
Answer:
Often in scientific work it is necessary to complement skills between researchers.
Explanation:
In research, it is imperative to work in collaboration with interdisciplinary groups of scientists. For example, geneticists work together with bioinformaticians to analyze how mutations may affect gene expression patterns in different tissues, cells, etc.
Omar often saw woodpeckers perched in trees in his backyard, but he never saw them at his bird feeders. Omar usually filled his feeders with sunflower seeds. He wondered if he could attract woodpeckers by adding a different type of food to the feeders.
To test this idea, Omar gathered eight identical bird feeders. He filled four with sunflower seeds. He filled the remaining four feeders with crushed peanuts. Omar then placed the bird feeders in his backyard. Over the next five days, he counted the number of woodpeckers that visited each bird feeder each morning.
Which of the following was an independent variable in this experiment?
Answer: The food
Explanation: the independent variable is the one to be changed and in this case, it is the food

Algae leave coral when the water is too warm. Temperature is a kind of abiotic factor in this relationship.
What do you mean by Mutualistic relationship?A Mutualistic relationship may be defined as when two organisms of different species work together, each benefiting from the relationship.
The temperature always remains an abiotic factor which is one of the important factors in the environment. Other abiotic factors are light, rainfall, fire, and winds.
Therefore, algae leave coral when the water is too warm. Temperature is a kind of abiotic factor in this relationship.

A scientist observed a phenotypic change in a mouse in her laboratory. This change was passed to the mouse’s offspring. What inference could the scientist make that would be supported by the observation?
a.
The phenotypic change is due to a mutation in a gamete.
b.
This mutation causes a disorder.
c.
This mutation has a positive impact on the mouse’s ability to survive.
d.
This mutation is the result of insertion of nucleotides.
Answer:
A
Explanation:
Mutations can occur in either cell type. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gamete s will carry the mutation and it will be passed on to the next generation when the individual successfully mates.

It has often been said that the next dominant animals on land, after a hypothetical demise of all mammals, would be the insects. Why so?
Explanation:
The animals that dominate the Earth today are the human species or Homo sapiens. Many factors have allowed the species to dominate the Earth-like use of new tools, vocal cords, and an increased sense of intellect and natural intelligence. But today we can observe the social wars, epidemic, and harm to our planet which could result in the extinction of humans.
The scientist has hypothesized that after the Homo sapiens, new dominating species will be insects as this group of the organism has:
1. Survived many mass extinctions.
2. are highly adaptable to extreme conditions.
3. Has evolved many adaptive features to protect itself from prey like a tough exoskeleton, few to many legs, bombarding in few species when someone tries to eat it, and many others.
