If there are 14 chromosomes in pea plant cells, there are 7 chromosomes present in a gamete cell of a pea plant.
Chromosomes are thread like structure which are present in pair.
The chromosomes contain re genes and characters of the person.
The process of meiosis, result in half of chromosome in the daughter cells.
Thus, there would be 7 chromosomes present.

Layer F is the youngest rock layer on Earth.
Layer F is the oldest rock layer on Earth.
Layer F contains index fossils.
Answer:
The answer is D (contains index fossils)
Explanation:
As the astronaut moved away from Earth, the gravitational force between Earth and the astronaut will decrease.
The gravitational force can be described as a force that attracts any two objects having mass. The gravitational force is an attractive force because it always tries to pull masses together, it never pushes objects apart.
In the universe, each object with mass attracts every other object with a certain force, and that attraction force is directly proportional to the product of the masses of those objects.
The objects that are far apart from each other, don't pull on each other but the force is there and we can calculate it from the Gravitational Force Formula,
F = Gm₁m₂/r²
Where F is the gravitational force between two objects, m₁ is the mass of the first object, m₂ is the mass of the second object and 'r' is the distance between the centers of two objects.
The earth pulls everything towards itself because of the gravitational force. As the astronaut moved away from the earth the influence gravitational force of the earth or gravity will decrease.

A flashlight battery is an example of a chemical battery, specifically a type of electrochemical cell. It converts chemical energy into electrical energy through a chemical reaction.
Inside the battery, there are two electrodes, typically made of different metals or metal compounds, and an electrolyte solution. When the battery is connected to a circuit, a chemical reaction occurs at the electrodes, resulting in the flow of electrons from one electrode to the other.
This flow of electrons generates an electric current that powers the flashlight or any other device connected to the battery.
The chemical reaction within the battery is reversible, meaning it can be recharged by applying an external electrical current to reverse the reaction and restore the chemical energy within the battery.
In summary, a flashlight battery is an example of a chemical battery because it utilizes a chemical reaction to convert chemical energy into electrical energy for powering electrical devices.
