liquid
gas
plasma
Answer: Liquid
Explanation:
Liquid and gases are fluids as they can flow. Convection takes place when the the particles having more energy is replaced with the particles having less energy.
The hotter particles moves and takes place of the colder particles when a liquid is heated. The liquid that lies in the hotter region is less dense than the colder regions. So, less dense particles move to replace the more dense particles.
Hence, the correct answer is Option B
Answer:
Hypothalamus
Explanation:
The prefrontal cortex, hippocampus and the cerebellum are involved in memory formation.
The prefrontal cortex is involved in making decisions,forming goals and planning , it's also based on past memories.
The hippocampus is involved in forming long term memories and also in spatial navigation
The hypothalamus is the part of the brain responsible for the body's ability of homeostasis.it is also involved with endocrine control and works closely with the pitutary gland.
b. carcinogens.
c. pathogens.
d. antibodies.
Microscopic organisms that cause diseases are known as pathogens. They include bacteria, viruses, fungi, and parasites that invade and interfere with the host's functions, leading to diseases and infections.
The correct answer to the question, "Microscopic organisms that are disease-causing agents are called," is c. Pathogens. A pathogen is any organism that causes disease in its host. This includes a variety of organisms, such as bacteria, viruses, fungi, and parasites. They invade the host's body and interfere with its functions, leading to various diseases and infections. In comparison, toxins are the harmful substances produced by organisms, carcinogens are substances that can lead to cancer, and antibodies are proteins produced by the immune system to combat pathogens and toxins.

answer is d) structural
Explanation:
Answer:
Green house gases are the type of gases present in the air which have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are found naturally and are known to play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.
These green house gases absorb the emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.
But now a days due to increased in the concentration of green house gases like carbon dioxide and methane due to pollution and deforestation causing a great problem called as green house effect which lead to global warming and it a great concern for all the people now a days.
Greenhouse gases refer to the gases, which are crucial to maintaining a suitable temperature for life on Earth. Examples are methane, carbon dioxide, and nitrous oxide.
Greenhouse gases such as water vapor, methane, fluorinated gases, and carbon dioxide trap the sunlight and raise the temperature of the Earth keeping it warm.
The gases are a concern for the environment and life on earth as in the absence of these gases, the Earth's climate will be extremely cold and chilly.
These gases act as a protective blanket, saving them from infrared rays and other harmful rays. Also, the increased emission of these gases is leading to global warming, which is one of the major threats to life on Earth.
Thus, greenhouse gases are essential but their increased emission is a major concern for the planet.
