The definition of a scientific fact is some how different from the definition of fact, as it implies knowledge. A scientific fact is the outcome of a repeating careful observation or measurement by experimentation or other means which is also known as empirical evidence. These are the parts or steps to create a scientific theories. Various forms of observation and measurement progressed to fundamental questions about the scientific method, and the scope and validity of scientific reasoning.
2- Observation
Observation is the active form of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the scientific and recording of data via the use of scientific instruments.
3- Interference
Interference is what happens when two or more waves meet each other and it is totally Depend on the alignment of peaks and troughs of the overlapping waves, they might add up, or they can partially or entirely cancel each other.

What are reactants in a chemical reaction?(1 point)
substances that are formed by reactions
outputs
inputs
substances that speed up reactions
Answer
D
Explanation:
inputs are the substances put in to make a chemical reaction.
The reactants are the inputs that are combined to form a product. The correct option is C.
What is a chemical reaction?A chemical reaction is a process that converts one or more substances, known as reactants, to one or more different substances, known as products. Chemical elements or compounds are examples of substances.
The most important types of events in the universe are chemical reactions. Plants grow, produce fruit, and decompose to become compost for new plants through chemical reactions.
Humans (and all other animals) reproduce, digest, grow, heal, and think as a result of chemical reactions.
Nuclear reactions are processes that involve the atomic nucleus. Reactants are the input substances that take part in a chemical reaction.
Products are the substances that are formed. The properties of the products differ from those of the reactants.
Thus, the correct option is C.

what is cell cycle? in detail
Answer:
A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

7. Explain why there is a difference in the amount of oxygen taken in at rest and during the vigorous activity, (2
Answer:
Physical exercise leads to an increase in the arteriovenous oxygen difference in all individuals. As exercise intensities increase, the muscles increase the amount of oxygen they extract from the blood, and this therefore results in further increases in a-vO2 diff.
Explanation:
There is a difference in the amount of oxygen intake during rest and vigorous activity due to the higher amount of energy required during vigorous activity.
What is aerobic respiration?The breakdown of glucose in the presence of oxygen to generate carbon dioxide water and energy in the form of ATP and heat energy is called aerobic respiration.
Aerobic respiration is a characteristic of higher animals because of a higher level of energy required by them. The process of aerobic respiration produces higher levels of energy compared to the process of anaerobic respiration which is a characteristic of lower organisms.
When a person is performing a vigorous activity, the energy requirement increases. This increases the process of cellular respiration which requires oxygen.
Therefore, when a person is performing vigorous activity their oxygen intake is higher compared to when they are at rest.

an organism that invades a region can have negative consequences and not region what kinds of shifts can take place?
Invasive species provoke significant damages in the structure of native ecosystems. They also cause economical and socio-cultural problems.
------------------------------------
When talking about dispersion we refer to the change in a species´ range or distribution area.
When a species move and establish in a new area out of their original distribution range, they might be considered exotic or invasive, according to their
reproductive rate, population growth, and interaction with native species.The introduction of invasive species has ecological, economic, socio-cultural consequences. Once an invasive species has been established, it overgrows. In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment. They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-. They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species. They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
As they expand, they can also affect human in an economical manner and has socio-cultural effects. Many invasive species might cause crops loss by eating cultures. They attack farm animals. They affect buildings and other structures or ships by eating wood. They might even attack humans and cause health problems.

A football player gets tackled during the game, which of the following body systems is responsible for protecting their organs?
circulatory system
reproductive system
skeletal system
nervous system
Answer:
Skeletal system
Explanation:
the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
Answer:
I believe your best choice from the given choices above would be C) skeletal system. The bone structure within the human body, such as the rib cage for instance, provides protection for our organs and takes more impact rather than any of our organs. Without our skeletal system, we would have zero protection for our organs, increasing the chance of more internal body damage.

any of various organic compounds that are insoluble in water
Answer:
Explanation:
Here is a website that has a list of organic compounds that are not soluable in water, but the common examples are
https://www.chemistryscl.com/advancedlevel/organic/water-soluble-organic-compounds/main.html
"Alkane, alkene and alkyne belong to the hydrocarbon type. In hydrocarbons, there are only carbon - hydrogen bonds in the organic compound. So polarization is weak to make strong intermolecular forces between water molecules. Therefore, alkane , alkene and alkyne are not soluble in water."
"Benzene is not soluble in water because benzene cannot make strong intermolecular forces such as hydrogen bonds or dipole dipole interactions. "

what is inertia ? write down the relation between mass and inertia?
Answer:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
