The property of carbon is that it has six protons in its nucleus distinguishes it from all other elements. Hence. option A is correct.
What are the properties of carbon?The chemical element carbon has the atomic number six and the letter C assigned to it. It has a tetravalent atom, which means that four of its electrons can be used to create covalent chemical bonds. It is nonmetallic. The periodic table's group 14 includes it. The crust of the Earth contains 0.025 percent carbon.
When carbon atoms join together to form lengthy chains, this element can form. When carbon burns, it combines with oxygen to form CO2 (and sometimes carbon monoxide). The incomplete combustion of wood during the creation of charcoal results in a high-carbon product that can burn longer.
Different elements have different numbers of protons in their nucleus. Therefore, option A is correct.

A 20 N unbalanced force cause an object to accelerate at 1.5 m/s. What is the mass of the object?
Answer:
I believe it’s 13.33 m
Explanation:
Because a = Fnet / m
So if you plug the numbers in it’s : 1.5 m/s = 20n / m
Then you’ll want to cross multiply which it’ll be : 20n = 1.5m
Then you want to get m alone so you’ll divide 1.5 to both sides and that’ll leave you to
13.33 = m

What did you have to do to turn an atom that is labeled “+ion or -ion” into a “Neutral Atom”?
To make any neutral atom, it should balance an equal number of electrons and protons, with +ion having more protons, and -ion having more number of electrons.
What is a neutral atom?A neutral atom defines as an equal balance of electrons and protons, to make any atom into ions, it has to gain protons or electrons to make “+ion or -ion”.
All atoms are made of electron and proton in which their nucleus contains protons, a positive entity, and electrons, which surrounds the nucleus having a negative entity.
Ions are also a type of atom but have gain or loss of any number of electrons or protons. If any ion denotes +2 it shows having an extra number of protons.
Therefore, turning an atom that is labeled “+ion or -ion” into a “Neutral Atom” is done by adding or deleting the electrons.

Name the four ways muscle strength can be measured and briefly describe each, In this ansignment, you will expand your knowledge of muncle structure and numction by exploring muscle strength and contraction. Then you will no what you learn to answer some follow up questions Read the article and use the information to anwer the following questions
Hii!! (: The correct answers are:
Absolute strength measures maximum force.
Dynamic strength measures repeated motions.
Elastic strength measures exertion of force rapidly.
Strength endurance measures fatigue resistance.
Muscle strength can be measured in four different ways: manual muscle testing, isokinetic testing, isometric testing, and dynamometry. Manual muscle testing involves the use of a hand-held dynamometer to measure the amount of force generated by a muscle contraction.
What is the use of this test ?This type of test is often used to assess the strength of a person’s muscles in order to diagnose any physical impairments or evaluate the effectiveness of a rehabilitation program.
Isokinetic testing is a type of testing that measures the amount of force generated by a muscle contraction at a constant speed. This type of test is often used to evaluate the strength of a muscle group or to measure the effects of a rehabilitation program.
Isometric testing is a type of testing that measures the amount of force generated by a muscle contraction when the muscle is held in a static position.
This type of test is often used to evaluate the strength of a muscle group or to measure the effects of a rehabilitation program. Finally, dynamometry is a type of testing that measures the amount of force generated by a muscle contraction when the muscle is actively contracting.
This type of test is often used to evaluate the strength of a muscle group or to measure the effects of a rehabilitation program. These four different methods of measuring muscle strength can provide valuable insight into the strength and function of a person’s muscles.
Hence, Manual muscle testing is the most commonly used method, as it is the most cost-effective and can provide quick results. Isokinetic, isometric, and dynamometry testing are more expensive and time consuming, but provide more detailed information about the strength and function of a person’s muscles.

list and describe three factors that affect how quickly enzymes can work to catalyze reactions
Answer:
The correct answer is - temperature, pH, substrate concentration.
Explanation:
Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.
Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.
pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.
Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.
Where does most of the oxygen produced in photosynthesis
go?
Answer:
THE ATMOSPHERE
Explanation:
Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules

Why does the organism engage in dormancy, hibernation, or migration?
Answer For,
Why does the organism engage in dormancy, hibernation, or migration?
Explanation:
Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy.
Hibernation is an adaptation that helps many animals conserve energy by remaining inactive, greatly slowing their metabolism and reducing their body temperature for days, weeks or even months at a time. Typically, animals hibernate in order to survive long periods when food is scarce.
Some animals travel relatively short distances to find food or more favorable living or breeding conditions. Most animals that migrate do so to find food or more livable conditions. Some animals migrate to breed. The Atlantic Salmon begins its life in a river and migrates downstream to the ocean.
