Beekeeping (or apiculture, from Latin apis, bee) is the maintenance of honey bee colonies, commonly in hives, by humans. A beekeeper (or apiarist) keeps bees in order to collect honey and other products of the hive (including beeswax, propolis, pollen, and royal jelly), to pollinate crops, or to produce bees for sale to other beekeepers.

Explanation:
The branch of biology that studies the different structures and functions of the cell is called Cell Biology or Cytology.

Cell biology (formerly called Cytology), is a Greek word: kytos, “vessel” is a branch of biology that studies the different structures and functions of the cell and focuses mainly on the idea of the cell as the basic unit of life.

The cell (from Latin cella, meaning “small room”) is the basic

Structural,
Functional (and)
Biological unit of all known living organisms.

A cell is the smallest unit of life that can replicate independently, and cells are often called the “building blocks of life”.

The rib cage surrounds the lungs and the heart, serving as an important means of bony protection for these vital organs. In total, the rib cage consists of the 12 thoracic vertebrae and the 24 ribs, in addition to the sternum.

The term ‘ozone hole’ refers to the depletion of the protective ozone layer in the upper atmosphere (stratosphere) over Earth’s polar regions. Stratospheric ozone is constantly produced by the action of the sun’s ultraviolet radiation on oxygen molecules (known as photochemical reactions).

Plants receive their nutrients mainly from soil.

There are total 24 ribs (12 pairs), out of which 14 (7 pairs) are true ribs

In Maize and Sugarcane, roots arise from the first few nodes of the stem and penetrate obliquely down in to the soil and give support to the plant. They are called Stilt roots.

Sodium bicarbonate is baking soda.

Notes:
Plasmodium, a tiny protozoan is responsible for malarial disease. Different species of Plasmodium (P. vivax, P. malaria and P. falciparum) are responsible for different types of malaria. Of these, malignant malaria caused by Plasmodium falciparum is the most serious one and can even be fatal.

Spontaneous emission of radiation, either directly from unstable atomic nuclei or as a consequence of a nuclear reaction. The radiation, including alpha particles, nucleons, electrons, and gamma rays, emitted by a radioactive substance.

Xylem and Phloem tissues are present throughout the plant. They begin at the root and then move up to the stem, branches, and leaves. The xylem tissue transports water and minerals from the roots to the leaves whereas the phloem tissue transports food from the leaves to the other parts of the plant.

The  correct answer is Sodium

Sodium, chloride, and potassium ions are essential for the transmission of nerve impulses.

Lion fish are noted for their venomous fin spines, which are capable of producing painful, though rarely fatal, puncture wounds.

 Enzymes are proteins that act as catalysts within the living cells. They are composed of one or more long chains of interconnected amino acids. They accelerate chemical reactions. All chemical reactions that occur in living organism are dependent on catalytic actions of enzymes and therefore, known as Bio transformation. Life would not exist without the presence of enzymes.

Cerebellum consists of large mass having ridges and furrows, situated above and behind the medulla and attached to cerebrum. It regulates muscular movement for locomotion. It is a part of brain.

Digestion of food starts as soon as we put food in our mouth. The mouth cavity contains teeth, tongue and salivary glands. The teeth cut the food into small pieces, chew and grind it. The teeth help in physical digestion. The salivary glands help in chemical digestion by secreting enzymes.

Charles Robert Darwin gave the theory of evolution in his book “The Origin of Species”. The theory proposed by him is known as “The Theory of Natural Selection”.

Plants are autotrophs as they prepare their own food with the help of photosynthesis and also green in colour due to the pigment chlorophyll present in the leaves. With the help of questions we have understood the necessity of it and also the process involved in the preparation of food and releasing oxygen in the environment.

omnivore an animal that eats both plants and meat. An animal that only eats plants is called a herbivore and an animal that only eats meat is called a carnivore.

The process of removal of toxic wastes from the body of an organism is called excretion.
