An inherited behavior that helps an animal meet its needs
Answers
Answer:
the answer is adaptations
Explanation:
A body part or behavior that helps an animal meet its need in its environment is called an adaptation. All adaptions are inherited traits. Camouflage is an animal's color or pattern that help it blend in with its surroundings.

Answer: To find Dave's speed, you can use the formula for speed, which is:
Speed = Distance / Time
In this case, Dave ran 2000 meters in 25 minutes. First, you'll need to convert the time to hours, as speed is typically measured in meters per second or meters per hour. There are 60 minutes in an hour, so:
25 minutes = 25 / 60 = 5/12 hours
Now, you can calculate Dave's speed:
Speed = 2000 meters / (5/12) hours
To divide by a fraction, you can multiply by its reciprocal (flip it):
Speed = 2000 meters / (5/12 hours) = 2000 meters * (12/5) hours
Now, calculate the speed:
Speed = 4800 meters per hour
So, Dave's speed is 4800 meters per hour.

Elements in the same groups shows similar chemical and physical properties. The elements having similar chemical properties are Be and Mg.
What are groups?
A group in periodic table is a column with elements of similar physical and chemical properties.
Both beryllium (Be) and magnesium are in group two with two valence electrons and both are metals. They have similar chemical and physical properties.
Cl is in 17th group and Ar is a 18th group element. They do not show any similarity in chemical properties. One is halogen which is unstable and the second one is noble gas which is stable. Thus no similarity.
Ca is a 2nd group element and Br is 17th group and they are different in chemical properties. One is metal and the second one is halogen with higher electronegativity.
Similarly, Na is in first group and P is 15th group element in periodic table in periodic table and does not show chemical similarities.
Therefore, the elements showing similar chemical properties are Be, Mg thus, option 1 is correct.

atoms are made of 3 types of sub atomic particles- protons, neutrons and electrons
from these 3 particles, electrons are responsible for participating in chemical bonds. therefore chemical properties of elements are based on the number of electrons present.
valence electrons are the number of electrons in the outermost energy shell that are involved in chemical bonds.
atoms with same number of valence electrons are grouped in to columns called groups.
therefore elements of the same group have same number of valence electrons, hence similar chemical properties.
from the options given
only Be and Mg belong to the same group they both belong to group 2 with 2 valence electrons
therefore Be and Mg have similar chemical properties
answer is
1) Be and Mg

Final answer:
A solution can exist in three phases: solid, liquid and gas, depending on the temperature and pressure. The pH of the solution can also change based on the nature of ions present in it. Understanding the nature and properties of solutions is crucial for many chemical reaction processes.
Explanation:
A solution can exist in three phases depending on the temperature and pressure, which are: gas, liquid, and solid. These are depicted in a phase diagram (an illustrative depiction that shows the states of a substance under different conditions of temperature and pressure).Consider the phase diagrams for a pure solvent and a solution. When a nonvolatile solute is dissolved in a solvent, a solution is formed. These states coexist and are in a state of thermal equilibrium at specific combinations of pressures and temperatures.
In addition to the physical phase, the pH of the solution can also be considered as a 'phase.' The pH can decrease, increase, or even show a pattern of increase and then decrease depending on the nature of ions present in the solution.
Solutions are crucial to life-sustaining processes as well as other chemical reaction processes. It's important to know the nature of solutions and factors determining its formation and properties for understanding various biological, geological and industrial processes.

(2) Magnesium conducts electricity.
(3) Magnesium reacts with an acid.
(4) Magnesium has a high boiling point.
Answers
Justification:
1) Malleability, conduction of electricity, and boiling point are physical properties.
2) Maleability is the ability to be transformed into foil. It is just a change in form. So, it is a physical property.
3) The metals conduct electricity in virtue of the array of the atoms, which permtis the flow of the electrons, but it does not involve a chemical change, so it remains being a physical proerty.
4) Boling point is the temperature at which a substance passes from liquid state to gas state, which are just different forms of the same substance. So, it is other physical property.
5) Reaction with an acid is indeed a chemical transformation: the metal (magnessium) will form a chemical bond with some spieces of the acid to form a new compound. This is a chemical reaction in virtue of the chemcial properties of the substance (its ability to react with acids)
Magnesium reacts with an acid.
