which best describes the big bang theory
Answer:
The expansion and cooling of the universe from an originally hot and dense state.
Answer: D. The universe formed during a single event in which all matter and energy suddenly expanded from an extremely small, dense, and hot point of pure energy called a singularity.

what three animals are closley related to a tiger
Answer:
The tiger's closest living relatives were previously thought to be the Panthera species lion, leopard, and jaguar.
Explanation:
Results of genetic analysis indicate that about 2.88 million years ago, the tiger and the snow leopard lineages diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar. The geographic origin of the Panthera is most likely northern Central Asia or the Holarctic region. The tiger–snow leopard lineage dispersed in Southeast Asia during the Miocene.
Panthera zdanskyi is considered to be a sister taxon of the modern tiger. It lived at the beginning of the Pleistocene about two million years ago, its fossil remains were excavated in Gansu province of northwestern China. It was smaller and more "primitive", but functionally and ecologically similar to the modern tiger. It is disputed as to whether it had the striping pattern. Northwestern China is thought to be the origin of the tiger lineage. Tigers grew in size, possibly in response to adaptive radiations of prey species like deer and bovids, which may have occurred in Southeast Asia during the Early Pleistocene.
Matthias Schleiden proposed that a plant grows by the division of cells and is composed entirely of cells. Which component of the cell theory is supported by Schleiden’s contribution?
The activity of an organism depends on the energy it consumes.
The activity of an organism depends on the energy it consumes.
All living organisms are made up of one or many cells.
All living organisms are made up of one or many cells.
All cells are physically and chemically similar.
All cells are physically and chemically similar.
Energy flow occurs within cells.
Answer: All living organisms are made up of one or many cells.
Explanation:
In 1830s, botanist Matthias Schleiden studied the tissues individually and proposed the cell theory for the first time. According to him all the living beings are made up of cells and cell is the basic unit of life.
As according to him in the cell division he was able to observe that the plants are made up of cells. This observation is indicating towards the fact that all living organisms are made up of one or many cells.
true or false? diffusion involves the movement of gases and solutes
Answer:
true
Explanation:
1)What is a trophic level?
2) explain how energy travels through food web ? your response must include the following terms:
Decomposer,producer, primary, consumer , 10%.
3)why is energy reduced at successive trophic levels?
1. The trophic level is something's position in the food chain/food web.
2. Energy travels through out the food chain because all the animals eat each other and take each other's energy. The decomposers are eaten, the producers are eaten, but the primary consumers get all the energy.
3. The energy decreases because each animal decomposes the energy a little, before getting eaten. By the time the food reaches the top of the web, the energy is barely left.

How are photosynethis and cellular respiration similar? And how are they different ?
Answer:
Photosynthesis, carried out by sunlight-reliant producers, requires carbon dioxide and releases oxygen and glucose, while cellular respiration (carried out by animals) requires oxygen and releases carbon dioxide and ATP. However, they both are biological processes that supply the organism in question with energy.
Explanation:
Answer:
The answer will be listed below.
Explanation:
The two processes, photosythesis and cellular respiration, are similar in that they both produce energy. These are ways for organisms to produce their food. Although, these two processes are completely different from each other. Cellular respiation occurs in all living organisms while photosythesis occurs only in phototrophs. Photosythesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into ATP, and then release waste products.

A mineral forms in water heated by magma inside Earth. Which statement best describes this mineral? The mineral formed through evaporation. The mineral crystallized from molten material. The mineral formed when a hot water solution cooled. The mineral likely has all the same properties as the surrounding rock.
Answer:
The mineral formed when a hot water solution cooled.
Explanation:
The mineral is formed from hot water solution heated by magma in the Earth when the water is cooled because when hot water solution is heated by magma in the Earth, it begin to cool underground, then the elements and compounds present there move out of the water solution , after these, these elements and compounds then undergo crystallisation and form minerals . Pure metals that crysralise from hot water solution is called Veins.
A mineral forms in water heated by magma inside Earth, when the hot water solution cooled.
Minerals formed from heated water by magmaA mineral is formed from hot water solution heated by magma in the Earth when the water is cooled.
When hot water solution is heated by magma in the Earth, afterwards it begins to cool underground, then the elements and compounds present in the solution move out of the water solution.
After this process, the separarted elements and compounds undergo crystallisation and form minerals. The minerals formed in this process are called veins.

What happens to the matter and energy in fruits as they decompose.
Please help! I really need help in science and no one in my family can help me! I will ask more science questions after this just in case you can help with those too
Answer:
During the process of decomposition, the decomposers provide food for themselves by extracting chemicals from the dead bodies or organic wastes; using these to produce energy. The decomposers will then produce waste of their own. In turn, this will also decompose, eventually returning nutrients to the soil.

(Environmental) Southern England What are the major concerns about soil erosion on arable land in Britain?
Answer:
Soil nutrient loss
Algae blooms
Pollution of water ways
Explanation:
Soil nutrient loss - a major concern as when soil erodes, this results in nutrient run off. Heavy rains can "wash away" essential nutrients within the soil therefore reducing the fertility of the land.
Algae blooms - when nutrients run off soil as a result of soil erosion they can leech into nearby fresh stream and even into salt water marine environments. This large increase of nutrients results in algae thriving and forming a layer across the top of the water. This reduces the oxygen and sunlight available to other marine plants and essentially suffocates plant and animal species.
Pollution of water ways - The sediment of soil that is eroded makes its way into fresh water ways can not only "bury" plant species and reduce biodiversity but it also reduces the water quality. It can introduce pathogens to the water from liverstock farming as well as introducing pesticides that may be harmful to wildlife.
It is difficult to make conclusions about scientific data collected from fossilized remains because the data
Answer: Fossils are rare because most remains are consumed or destroyed soon after death. Even if bones are buried, they then must remain buried and be replaced with minerals. If an animal is frozen like the baby mammoth mentioned above, again the animal must remain undisturbed for many years before found.
