The big band theory is a guess about how the universe came into existence. It started with an infinitely hot and dense single point. Later on got inflated and stretched at an unimaginable speed.
The shifting of the starts and cooling down is not one of the pieces of evidence that are offered by the big band theory.Hence the option C is correct.

Did
you have any leftover atoms after creating the
oxygen and the glucose?
After creating the oxygen and the glucose in the process of photosynthesis, there are no atoms left, and the products of the photosynthesis are used for different purposes, such as cellular metabolism and respiration.
What is the importance of the product of photosynthesis?Photosynthesis is a process in which the product is glucose, which is made up of carbon, hydrogen, and the oxygen atom, and the oxygen gas that is released to the environment. Water, which is composed of hydrogen and oxygen, and carbon dioxide, which is composed of carbon and oxygen, are the reactants in this process and make the glucose in the presence of sunlight; further, these are used by animals and plants.
Hence, after creating the oxygen and the glucose in the process of photosynthesis, there are no atoms left, and the products of the photosynthesis are used for different purposes, such as cellular metabolism and respiration.

How does a rock change into a metamorphic rock?
A. evaporation
B. cementation and compaction
C. heat and pressure
D. cooling of magma
Answer: C
Explanation:
Any rock (igneous, sedimentary, or metamorphic) can become a metamorphic rock. If rocks are buried deep in the Earth at high temperatures and pressures, they form new minerals and textures all without melting. If melting occurs, magma is formed, starting the rock cycle all over again.
Answer:
C
Explanation: The heat and pressure changes the rock into a different type of rock such as igneaous, metamorphic, and sedimentary.
Plants are autotrophs, organisms that produce their own food through the process of photosynthesis. The chemical reaction that describes photosynthesis is shown below. How does reducing the amount of light energy affect the products of photosynthesis?
Answer:
Reducing the amount of light energy also reduces the rate at which products are formed.
Explanation:
According to this question, plants due to their ability to capture light energy using their chlorophyll pigment are said to be autotrophs i.e. perform photosynthesis to obtain their food. Photosynthesis is a process that requires light energy from the sun, and it can be measured by the amount of O2 and glucose produced as PRODUCTS.
However, in a case where the amount of light energy is reduced, this means that the amount that will be captured by chlorophyll will be low, hence, reducing efficiency. This means that reducing the amount of light energy also reduces the rate at which products are formed.
The negative impacts of nonnative species generally outweigh the positive impacts. Please select the best answer from the choices provided О T O F
Answer:
true
Explanation
The negative impacts of nonnative species generally outweigh the positive impacts. Thus, the given statement is true.
What are non-native species?An alien or non-native species is the species which has been intentionally or accidentally transported and released into an environment which is outside of its historic or resident geographical range or habitat. The species is introduced into a new habitat. Such species are known as invasive species, if they are ecologically and economically harmful to the environment.
It has been found that the negative impacts of non-native species generally outweighs the positive impacts. This is because, these species disturb the ecosystem of the new environment in which it is introduced. Disturbance in the ecosystem is caused due to disturbance in the food chain.

Which cell structure would you find in a bacteria?
A
nucleus
B
mitochondria
C
ribosome
D
chloroplast
Answer:
nucleus
Explanation: Every single sell must have a nucleus so nucleus is the correct answer.
Ribosome is the cell structure would you find in a bacteria.
Ribosomes are the cellular structures where proteins are synthesized and found in the bacterial cytoplasm.
The cytoplasm is the part of the cell that is within the cytoplasmic membrane and is composed of nutrients, waste, and gases and contains cellular structures such as ribosomes, chromosomes and plasmids.
Bacterial ribosomes consist of two subunits with sedimentation constants of 30 S and 50 S respectively.
The ribosome is active when its two subunits are associated, and the concentration of Mg ++ is of great importance in their association and dissociation process.
In the bacterial cytoplasm there is a clear spatial and functional separation between the central zone.
The nucleoid is located and in which transcription occurs, with respect to the peripheral zone rich in ribosomes, in which protein synthesis occurs.
Therefore, we can conclude that ribosome is the cell structure would you find in a bacteria.

Explain a time you would need to evaluate something in science.
Answer:
To study if the reuse of industrial treated wastewater may adversely affect life in a river basin system
Explanation:
The process of evaluation in science enables us to understand a given phenomenon from the natural world. Scientists have a standardized-objective method to investigate how the natural world works. This scientific method consists of the following steps: 1- to observe a given phenomenon form the real world, 2- to ask one or more questions about this phenomenon, 3- to raise a working hypothesis in order to explain these questions, 4-to test the hypothesis by experimental and/or observational procedures, 5- to obtain the results and conclusions. In this case, the scientific method can help to understand the effects of the industrial treated water in the life of the river system, and these results could be used as a starting point to predict its effects on other aquatic ecosystems.

Explain how a nuclear power plant uses the process of nuclear fission to produce electricity.
Answer: In nuclear power plants, neutrons collide with uranium atoms, splitting them. In the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity.
A nuclear power plant uses a nuclear fuel which undergoes bombardment by neutrons to produce energy.
Nuclear fission involves the bombardment of a fissile nucleus such as U-235 with a neutron. This results in the initiation of a chain reaction in which daughter nuclei are produced and tremendous energy is released,
The energy released in the process is used to heat water to produce steam. The steam thus produced turns a large turbine to generate electricity.

Which of the following is an example of a pioneer species?
a. fungus
b. trees
c. shrubs
d. grass
Answer:
fungi
Explanation:
The grass is an example of pioneer species. Therefore, the correct statement is option D.
What is pioneer species?
Pioneer species involve the organisms that are first to colonize a newly formed or well-disturbed ecosystem. These species can grow in harsh environments, such as abandoned fields, or rocks.
Grasses are the pioneer species that can easily grow in harsh environments and establish and grow themselves in soils that contain poor nutrients. However, the growth of grasses in the soil enriches the soil with organic matter and makes the soil nutrient rich making it a suitable environment for other plants to grow.
When the grasses growing in the area makes the soil nutrient-rich, other plants such as shrubs and trees also begin to grow in that area, and with time, they replace the grasses as the dominant plant species.
Therefore, the grass is an example of a pioneer species.

Explanation:
Which of the following explains why polar latitudes have a solar radiation deficit?
Answer:
The correct answer is - True.
The polar latitudes have a solar radiation deficit, and that is because of the shape of the Earth, and because of the way the Earth rotates and revolves.
The shape of the Earth, which is ecliptic, doesn't allow the solar radiation to have the same impact on every place on the planet. On the polar latitudes, the problem with the deficiency of solar radiation is because the sun rays fall at a very sharp angle, which means that the same rays are dispersed over a much larger territory, thus the heat is not concentrated, and these parts warm up much less.
The rotation and revolving of the Earth, also goes into the favor of the Equator, but not in the favor of the poles, as the Earth is rotating in an west-east manner, and while rotating it remains its track in a way in which the Equator is the most exposed to the solar radiation, but not the poles
