Answer:
The given statement is true.
Explanation:
The oxygen that is present in the atmosphere has two main sources:
Terrestrial Plants: As we know that the plants make use of sunlight, water, carbon dioxide and chlorophyll in a process termed as photosynthesis and make glucose and releasing oxygen into the atmosphere which is then used by animals for respiration. This is one of the major source of oxygen in the atmosphere.
Oxygen released from Oceans: In the oceans of the earth, water bodies ,seas tiny plants termed as Phytoplankton are present that are present near the surface of the water bodied that also release oxygen by photosynthesis and account for about 50% of the world's oxygen supply.
First, we want to know the average length of each cell. If you have 100 cells in a 1 millimeter space, we would do 1 ÷ 100. 1 ÷ 100 = 0.01 millimeters. Hope this helped!
Answer:
Newton's law of Universal Gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Explanation:
The force of gravity is an attractive force between two objects with mass. The force of gravity is directly proportional to both objects masses, and has an inverse square relationship with the distance between the objects' centers.
Answer:
Domains
Explanation:
Living organisms are divided into three domains:
Archaea
Eubacteria
Eukarya
Organisms are divided into these three domains based on genetic similarities or closeness. Archaea and Eubacteria are domains that consist of prokaryotes or prokaryotic cells.
Prokaryotes in the domain Archaea differ from those in Eubacteria because of certain characteristics like their ability to live in extreme environments and the absence of the peptiglycan in their cell walls.
Prokaryotes in the Eubacteria domain have peptidoglycan walls and RNA unique to them.
Organisms uner Eukarya, as the name suggests, have eukaryotic cells meaning the have an enclosed or membrane-bound nucleus.
They hypothalamus is responsible for the regulation of certain metabolic processes and other activities of the autonomic nervous system. It controls body temperature, hunger, thirst, fatigue, sleep etc. It is located in the brain below the thalamus.
