Explanation:
Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

An atom is the smallest particle of a substance that has all the properties of the substance.
Every atom is composed of a nucleus and one or more electrons which are bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons as well. Only the most common variety of hydrogen has no neutrons in it.
The electrons of an atom are attracted to the protons in an atomic nucleus through the electromagnetic force. The protons and neutrons in the nucleus are attracted to each other with the help of nuclear force. This force is usually stronger than the electromagnetic force which repels the positively charged protons from one another in the nucleus. Under certain circumstances, the repelling electromagnetic force between protons become stronger than the nuclear force. In this case, the nucleus splits and leaves behind different elements. This is a type of nuclear decay.

A snake eating a mouse is an example of predation in biology.
A snake that eats a mouse is an example of predation in biology. Predation is the act of one organism (the predator) killing and consuming another organism (the prey). Snakes are carnivorous and rely on predation to obtain their food. This relationship is a fundamental aspect of the natural world and plays an important role in ecological dynamics.
Thus, it is an interaction in which one organism, known as the predator, hunts, captures, and consumes another organism, called the prey. It is a crucial ecological process that regulates populations, influences species dynamics, and contributes to biodiversity. Predation shapes ecosystems by controlling herbivore populations and affecting prey behavior and adaptations.

Answer:
Crossing over
Explanation:
for variations which is one of the most important characteristic for Meosis
b_All the atoms lie in a line.
c_The bonds orient in a tetrahedral fashion.
d_All the atoms lie in a plane.
e_The groups rotate around the C=C bond.
Two C atoms form a double bond. Each C is bound to two H atoms. All the atoms lie in a plane. Thus option D is true.
The atom is the basic unit of a matter, it consist of three sub atomic components such as proton, neutron and electron, where proton and neutron present at the central nucleus of atom and electron surround the nucleus.
Proton is positively charged, neutron is neutral and electron is negatively charged; the total number of protons in an atom called as proton number or atomic number which is denoted by the capital letter Z
This number is always a whole numbers range from 1 to 118 according to periodic table element and in an electrically neutral atom the number of electrons is equal to the atomic number.
Thus option D is true.

Answer:
All the atoms lie in a plane
- the double bond limits all the atoms to a plane
