According to the article, why is a faulty hypothesis still an acceptable outcome to scientists
Answer:a
Explanation:
all compounds are negatively charged, true or false?
Answer:
false
Explanation:
"Electrons are the "material" of the charge that is flowing. Therefore, current can never cause a metal object to become positively or negatively charged, because the net number of electrons in the metal object will never change due to current flow."
A mutation that causes abnormal cell division can result in
1.) cystic fibrosis.
2.) clogged arteries
3.) sickle cell anerna aneria
4.) skin cancer.
The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.
What can happen if a mutation results in aberrant cell division?Gene mutations can increase the pace of cell division or suppress natural mechanisms that keep the body in check, like cell cycle arrest or programmed cell death. A tumour can form as a collection of malignant cells enlarges.
hence, skin cancer
Proteins are made from information found in genes, and proteins regulate a number of vital processes, including cell growth. Protein function can be altered by genetic alterations. Certain kinds of genetic changes to proteins result in healthy cells can become cancer.

Why do scientist study ice cores
Select all that apply
To study Earth's past climates
To study how Earth's climate is changing now
To study how climate typically stays the same
To study how it might change in the future
Answer:
to study earth's past climate
Answer:
Explanation:
Air bubbles and dust get trapped in ice as it forms. And the ice in some places, like Antarctica, has stayed frozen for over a million years. Scientists drill holes in the ice and remove ice cores. Each year's worth of ice forms a layer within the core.
The material trapped in ice layers gives information about the climate at that time. Scientists study the layers to learn about past temperatures and precipitation. They can learn how the amount of carbon dioxide in the atmosphere has changed over time. The layers also reveal when events such as volcanic eruptions have taken place.

Thick Walled isodiametric dead cells
Answer:Sclerenchyma
Explanation:Sclerenchyma is thick walled dead lignified cells, they are hard and elastic. The sclerenchyma cells are divided into two groups namely fibers and sclereids. Sclerenchymatous fibers are branched/unbranched, long, hard, pointed cells with tapering ends, thick walls, and narrow lumen.
Answer:
Sclerenchyma is Greek word where "Sclero-" means hard and "enchyma" means infusion. This tissue consists of thick-walled, dead cells and protoplasm is negligible. These cells have hard and extremely thick secondary walls due to uniform distribution and high secretion of lignin and have a function of providing mechanical support

what is four the terrestrial planets
Answer:
Explanation:
Terresterial comes from the greek work "terra", which means Earth. So when you hear the word "terresterial " think that it means "like Earth". More specifically, it means that a planet is SOLID, like the Earth is. So, to figure out the answer to your question, let's list the planets starting with the ones closest to the sun and work out way out toward deep space. We can also describe each planet a bit as we list them.
Mercury - Closest to the Sun and, because of that, its very hot here. A lot of the ground on this planet is lava made of molten metal which is a liquid BUT there is also solid ground so it is terresterial. ✓
Venus - 2nd closest to the Sun. There is ground here, so it's terresterial. ✓
Earth - 3rd closest to the sun. There is solid ground here too so... Terresterial ✓
Mars - Also Solid. Terresterial ✓
Jupiter - Jupiter is made of Gas. If you went there, there would be nothing solid to walk on, but instead simply pass through it like it was a cloud. Therefore it is NOT terresterial
Saturn - Also a "Gas Giant" plant. (They are called gas giants because these planets are huge! You could fit 764 planet Earths inside of Saturn and over 1300 Earths could fit inside Jupiter!) Gas = NOT terresterial
Uranus - Another Gas Giant. Not terresterial
Neptune - The last of the gas giant planets and the furthest from the Sun. Again, its made of gas so its... not terresterial!
If you have trouble remembering the order, try memorizing this:
"My - Very - Epic - Mother - Just - Served - Us - Nachos"
Mercury - Venus - Earth - Mars - Jupiter - Saturn - Uranus - Neptune

all of the above
Answer:
all of the above
Explanation:
Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.
For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.
Explain how Earth’s atmosphere affects solar radiation
Answer:
Explanation: Three atmospheric processes modify the solar radiation passing through our atmosphere destined to the Earth's surface. These processes act on the radiation when it interacts with gases and suspended particles found in the atmosphere.
The three main atmospheric components that absorb radiation are ozone, carbon dioxide, and water vapour. The sun's UV energy, which is detrimental to the majority of living organisms, is absorbed by ozone. Without the atmosphere's protective barrier, sunlight would cause our skin to burn.
What Earth’s atmosphere affects solar radiation?29% of the solar energy that strikes the Earth is returned to space as a result of reflection, largely from clouds but also from other brilliant surfaces and the atmosphere itself. Approximately 23% of the energy entering the environment is absorbed by atmospheric gases, dust, and other particles.
Therefore, The solar radiation that enters our atmosphere and is directed toward the Earth's surface is altered by three atmospheric processes. When radiation interacts with gases and suspended particles in the atmosphere, several processes impact the radiation.

Explanation:
because lakes have trees that create the fresh water for the fishes to swim in i think?
An example of a freshwater wetland body is a lake. Thus, the correct option is B.
What is a lake?A freshwater wetland is a waterbody which is supplied with water from all the nearby streams and rivers. Freshwater wetlands are the ecosystems which are affected by the permanent or temporary inundation.
A lake is a naturally occurring, relatively very large body of water which is localized in a basin that is surrounded by land, with much slower-moving flow than that of any inflow or outflow streams that serve to feed or drain the lake. Lakes lie completely on the lands and are separate from that of the ocean, however like the much larger oceans, they also form a part of the Earth's water cycle by serving as many large standing water reservoirs as possible. Most of the lakes are freshwater, however some are salt lakes with salinities even higher than that of the seawater.
Therefore, the correct option is B.

The prefix cyto- means “cell.” The suffix -logy means “study.” How does knowledge of these word parts help define cytology?
Cytology is the study of cells, and understanding the terminology's components aids in its definition. The Greek word "kytos" which meaning "cell" is whence the prefix "cyto" gets its name.
What is the meaning of the word ?The Greek word "logia" (which meaning "study") is where the suffix "-ology" comes from. So, "cytology" can be defined as "the study of cells" when used collectively. The study of cell structure, function, and pathology is the focus of the biological field known as cytology.
Cells must be examined under a microscope and subjected to a variety of analyses to determine their structure and function. As a tool for identifying cancer cells, diagnosing diseases, and researching the impact of medications on cells, cytology is a crucial area of science.
Additionally, it is employed to research how cells form and behave intracellular communication in a living organism.

Which of these zones of the ocean is most hospitable to life?
O A. Epipelagic
O B. Abyssopelagic
O C. Hadalpelagic
O D. Bathypelagic
Answer:
A.
Explanation:
The zones of the ocean which is most hospitable to life is the epipelagic zone. Thus, the correct option will be A.
What is the epipelagic zone?The Epipelagic zone can be referred to as the uppermost layer of the ocean. Epipelagic zone is located between the surface and the 600 feet in depth of the ocean. The Epipelagic Zone is also known as the Sunlight Zone. It is the region of the ocean which sits on the continental shelf in the oceans.
Epipelagic zone is in this thin layer which the process of photosynthesis takes place. The epipelagic zone of the ocean only represents about 2 to 3% of the entire ocean zone, beyond this zone, light is too dim for the process of photosynthesis to occur. This is the reason why, the epipelagic zone is the most hospitable zone of the life in oceans.
Therefore, the correct option will be A.
