Answer: The infrared radiations can detect the coolest and dimmest space objects.
In general, the coolest and darkest regions of space emit radiations of longer wavelengths. The Infrared telescope is used to find the cool, dim stars by slicing the interstellar dust bands and also measure the temperature of the planet of the solar system. The coldest stars do not emit light so they can be seen with the infrared telescopes only. In the visible region, blue stars are hottest and red are the coolest. The wavelength is inversely proportional to the energy emitted so the hottest stars are in the region of low wavelength in visible region.
The alveolus (singular form) or alveoli (plural
form) are tiny sacs of organs that are attached to the ends of the alveolar
duct. These tiny sacs of air are clumped together that form interconnected
caves, working together as a unit. They are found inside the lungs and they
make the exchange of air easy and possible. Alveoli units are responsible for
putting oxygen into the air that we breathe in. Blood that passes through the
heart and into the lungs are converted into oxygen which will be then
transported by the blood all over the body systems.

The walls of the alveoli are extremely thin to
enable the quick exchange of gases Aside from this, the linings of alveoli
units are fluid in nature enabling gases to dissolve. </span>
I have not learned that yet i wish i could help so sorry though good luck
Answer:
it helps in maintaining the redox balance in cells and also supports plant immune defences.
Answer:
A sensory neuron.
Explanation:
The nervous system can be divided in two systems: the central nervous system and the peripheral nervous system. The central nervous system (CNS) is composed by the brain and the spinal cord. The peripheral nervous system (PNS) consists of the nerves and ganglia. Neurons are specialized cells that form the basic functional unit of the nervous system. There are three types of neurons: sensory, motor and interneurons. The sensory neurons are in charge of bringing signals into the CNS, and the motor neurons are in charge of carrying signals out of the CNS. The interneurons act as intermediaries, passing information between two neurons.
As the name implies, sensory neurons are activated by the senses, for example: sound, visible light, physical contact (heat and cold), chemical signals (smell and taste). The loss of sensation in one hand would be the result of a damaged sensory neuron.
