Answer:
The correct answer is A.respiration
Explanation:
Cellular respiration is a process which produces ATP (adenosine triphosphate) and methabolites. ATP is an "energy coin" which provides energy for biochemical processes in all cells. The other options are not correct: meiosis is the division process of sexual cells, mitosis is the division process of somatic cells and photosynthesis ocurrs in plant cells to obtain energy (not in animal cells of muscle tissue).

Answer:
its d
Explanation:
B. the transmission of heat across matter
C. the electromagnetic radiation from the surface of an object which is due to the object's temperature
D. the transmission of heat across empty space
Answer: A. the transfer of heat by currents
Explanation: There are three modes of heat transfer:
1) Conduction: This type of heat transfer happens when there is direct contact between the two object. Example: heating a pan on stove.
2) Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) due to the movement of hot layers to the top and cold layers to the bottom which leads to convection currents. Example: Heating of swimming pool.
3) Radiation: This type of heat transfer happens when there is direct transfer of energy through space. Example: Heating of earth's surface.
B. The transmission of heat across matter is conduction.
C. The electromagnetic radiation from the surface of an object which is due to the object's temperature is radiation.
D. The transmission of heat across empty space is radiation.
Answer:
A: The transfer of heat by currents.
Explanation:
Convection is the transfer of heat by currents, typically within a liquid or a gas. When heat is transferred by convection, matter flows.
Lewis base is a substance that dissolved in water increases hydrogen ion concentration.
This is a chemical substance which is slippery to touch and reacts with acids to form salt.
A lewis base is capable of donating its lone pair of electrons thereby resulting in its ability to increases hydrogen ion concentration when in water.

A Lewis base is a substance that donates electrons to form a covalent bond. Therefore, option B is correct.
A Lewis base is a type of molecule or ion that has a pair of electrons. It can donate electrons to another atom or molecule to form a chemical bond. The concept of Lewis bases was introduced by the American chemist Gilbert N. Lewis in 1923, as part of his theory of chemical bonding.
In a Lewis acid-base reaction, the Lewis base (electron-pair donor) reacts with a Lewis acid (electron-pair acceptor) to form a new compound. Lewis bases are important in many chemical reactions, including acid-base reactions, coordination complexes, and redox reactions. Examples of Lewis bases include ammonia (NH3), water (H2O), and chloride ions (Cl-). Therefore, option B is correct.

B. Density
C. Melting point
D. Color
Answer : The properties which would be the same among isotopes of the same element are Flammability and Color
Explanation :
Isotopes are the elements that have same number of electrons and protons but they differ in number of neutrons.
The chemical properties of an element are determined by its valence electrons and since isotope have same number of electrons, they have similar chemical properties.
But isotopes have different number of neutrons. Neutrons are the subatomic particles which are present in the nucleus. They are charge less particles and they have mass. Therefore when the elements have different number of neutrons, their atomic masses differ.
As a result, isotopes have different mass related physical properties.
Let us discuss the given properties now
1) Flammability : Flammability in simple words means the ability of the substance to catch fire or the ability to burn. This is mainly dependent on the reactivity which is in turn dependent on the number of electrons.
Since the isotopes have same number of electrons, they show similar flammability.
2) Density : Density is defined as mass per unit volume. This property involves mass and we know that isotopes have different masses. Therefore they have different densities too.
3) Melting point : Melting point is a physical property which is mainly dependent on the molecular weight of the substance. Since isotopes have different masses, they tend to show different melting points.
4) Color : The color of the element is mainly dependent on the arrangement of electrons around the nucleus. Isotopes have same number of electrons which means the arrangement would also be the same. Therefore the isotopes of the same element do not show different colors.
The properties which would be same among isotopes of the same element are
1) Flammability
4) Color
