Select ALL of the abiotic factors
nataly862011 [7]

Answer:

light

Explanation:

An abiotic factor is a non-living component in the environment. This can be either a chemical or physical presence. Abiotic factors fall into three basic categories: climatic, edaphic and social. Climatic factors include humidity, sunlight and factors involving the climate. Edaphic refers to soil conditions, so edaphic abiotic factors include soil and geography of the land. Social factors include how the land is being used and water resources in the area. Five common abiotic factors are atmosphere, chemical elements, sunlight/temperature, wind and water.

Temperature and Light



•••

Temperature of the air and water affect animals, plants and humans in ecosystems. A rise in temperature has the potential to change the way a living thing develops, because it changes the metabolic rate of the organism. All living organisms have a tolerance level for temperature range. For example, a human being would die if he stood out in minus 50 degree temperatures for any length of time. Light exposure often affects the temperature. Areas with direct sunlight are warmer

Choose the FALSE statement about nerves. a) Nerve axons are surrounded by a loose connective tissue layer called the endoneurium
Zinaida [17]

Answer: The answer is C: Axons make up a majority of the matter in a nerve.

Explanation:

Nerves are cells of the brain and nervous system called Neurons. They make up the neurons and transmit messages from one part of the body to another.

Axons are long projections of a neuron which conduct electrical impulses known as action potential away from the nerve cell body.

Axons do not make up majority of the matter in a nerve because the length of axon branches are different from one neuron to another. They differ in length from about 0.1 micrometers to 2meters and many neurons do not have axons.
