Answer:

Answer to 1: a black hole is a tremendous amount of matter crammed into a very small (zero) amount of space. Answer to 2: the top of your head would feel so much more gravitational pull than the tips of your toes that you would be stretched, longer and longer Answer to 3: A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. because no light can get out, people can't see black holes Answer to 4: stellar, intermediate, supermassive, and miniature. Answer to 5: the asymmetry of bright and dark sections of the ring are caused by the Doppler effect as the matter is coming toward Earth (brighter) or receding (dimmer).

Design an experiment that would help you collect the data you have identified in question four independent variable - x , dependent variable - y.

What is independent variable?

The indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable.

The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.

The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.

1.


A. genetic modification


B. hybridization


C. natural selection



2.


A . competitors

B. predators

c.prey



3

a .increase

b. decrease

C. not change

Answers

Answer:

1 a 2b 3increase

Explanation:

Genetically fishes have gills to inhale they take water through gills and u know water has some amount of oxygen

2 predators increase because many fishes eat each other bcz of competition

3 so relating point 2 competition also increase

The fish developed the gills because of genetic modification . Because the fish are now able to swim in deep water, their predators in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will increase.

What are the adaptations of fish gills?

Gills are organs that filter oxygen from the surrounding water. The inside structure of gills is an adaptation that enables two processes to occur: acquiring oxygen and removing a waste product called carbon dioxide.

Fish are able to efficiently exchange gases thanks to the vast surface area of their gills, which allows for this process. The extensive amount of surface area that the blood capillaries in each gill filament contribute because of the little distance that must be traveled for diffusion, both the outer layer of the gill filaments and the walls of the capillaries are only one cell thick.

C. Where in the ocean do shrimp find the plankton that they eat?

Explanation:

A, because there's a food chain that's going to Plankton to shrimp and so on. That would be a scientific question they might ask about. It's also related to what the question is asking about and it's a more simple answer. I wouldn't think B or C is what they would ask about because it's not really related to the food chain. For D, it's a really good question. But, the food chain only shows a Plankton going to shrimp and so on. D is a bit more into deep thought and it doesn't really relate to the picture either.

Explanation:

Genes are located on many chromosomes. In other words, a particular section of the genome is located on each chromosome.

What are the main role of chromosome in the information?

The primary function of the chromosomes is to transfer DNA, the fundamental component of genetic material. The genetic instructions for numerous biological functions are encoded in DNA.

Chromosomes, which resemble threads, are located in the nucleus of both animal and plant cells.Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).

These processes are necessary for the development, maintenance, and procreation of the organisms.Proteins like histones, which protect the chromosomes.

defend Human Evolution against Scientific Creationism​

Answers

Answer:  According to the National Academy of Sciences (NAS), a scientific theory is “a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.” No amount of validation changes a theory into a law, which is a descriptive generalization about nature. So when scientists talk about the theory of evolution—or the atomic theory or the theory of relativity, for that matter—they are not expressing reservations about its truth.

Explanation: The theory of evolution, meaning the idea of descent with modification, one may also speak of the fact of evolution. The NAS defines a fact as “an observation that has been repeatedly confirmed and for all practical purposes is accepted as ‘true.’” The fossil record and abundant other evidence testify that organisms have evolved through time. Although no one observed those transformations, the indirect evidence is clear, unambiguous and compelling.

Evolutionary theory has been discussed, perhaps more than any other scientific concept, throughout the publication runs of Science and The Scientific Monthly. Eminent scientists and philosophers defined the debate, writing with clarity and grace, representing the best in scientific reporting and commentary. Selections from these two journals reflect the creationist–evolutionist controversy in the United States. Occasionally, creationist letters were published, more as comic relief than as serious opposition to evolution. Nevertheless, creationist activity was viewed as a threat to good science; considerable space was allocated to its coverage. Only articles dealing directly with the controversy are cited in this review; technical papers describing details of the development of evolutionary theory were disregarded.

Answer:

Precipitation levels are low, and the average temperatures are high.

Explanation:

The low latitude climates lie for the most part between the tropics of Cancer and Capricorn. They occupy the equatorial zone, most of the tropical zone, and part of the subtropical zone. Climates in this region tend to be extremely dry and hot.

Precipitation levels and average temperatures are high. Therefore, option (A) is correct.

What is a low latitude climate zone?

Low latitude climate zones are regions of the world that are located near the equator and have relatively consistent weather patterns throughout the year. These zones are characterized by high temperatures and abundant precipitation, which support a diverse range of plant and animal life.

The vegetation in these regions is typically lush and green, with tropical rainforests, savannas, and wetlands being common types of ecosystems. Low latitude climate zones are home to a wide variety of wildlife, including primates, big cats, and a vast array of bird species. These regions are also important for human habitation, with many of the world's largest cities located within the low latitude zone.

Overall, the low latitude climate zone is a hot and humid environment that supports a rich and diverse ecosystem. Therefore, option (A) is correct.
