Explanation
In the modern periodic table, there are 7 periods (horizontal rows) and 18 groups (vertical columns).

Explanation
A reaction in which heat is absorbed is called an endothermic reaction. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect.

Explanation
The modern periodic table is arranged by increasing atomic number (number of protons). This arrangement resolves inconsistencies in earlier tables and groups elements with similar properties together.

Explanation
The hertz is the unit of frequency  of one cycle per second.   symbol: hertz (Hz) Hertz in honor of the German physicist Heinrich Hertz hertz in the International System of Units (SI) frequency i s defined as one cycle per second ***

Explanation
The Mole (mol) is the SI unit of amount of substance, representing 6.022 x 10^23 particles. It is used to measure the amount of a substance in a sample.

Explanation
The mass of Earth is approximately 6.0 x 10^24 kilograms ( 5.98 x 10^24 kg ). This is a widely accepted scientific value , based on various measurements and calculations, including: Gravity measurements Satellite orbits Seismological data Planetary formation models

Explanation
The s tratospheric ozone layer  is Earth's “ sunscreen ”  protecting living things from too much  ultraviolet  radiation from the sun. Oxygen layer in the  atmosphere Ozone   protects  us from the harmful ultraviolet radiation of the sun. Ozone  formula : O3 The ozone layer lies approximately  15-40 kilometers  (10-25 miles) above the Earth's surface, in the stratosphere. The ozone layer is  depleting : Air pollution

Explanation
Vitamin D deficiency can cause Rickets , a disease characterized by: Soft and weak bones Skeletal deformities Stunted growth Increased risk of fractures

Explanation
Omnivores are animals that eat both plants and animals . They have adaptations that allow them to digest and extract nutrients from a wide variety of food sources, including fruits, leaves, insects, small animals, and even carrion. Examples of omnivores include humans, bears, pigs, chimpanzees, and raccoons . Only plants : Herbivores (e.g., cows). Only animals : Carnivores (e.g., lions).

Explanation
Ecology is the study of interrelationships between organisms and with their environment. It is also known as environmental science. It's a branch of biology that examines how living things interact with their physical surroundings.
