The coastal environment, or littoral zone, is considered to extend seaward as far as _______. the coastal environment, or littor
SIZIF [17.4K]
The correct choice is that it extends until depths of around 60 m where sediments cannot move anymore. The important thing is that it certainly is not just the contact point of water and land; it goes into the sea until this point, where also enough light reaches the bottom for plants to do photosynthesis. D is wrong because breakers do not play a role in this definition, although it can vary from context to context (sea, lakes etc.).

A team of astronomers discovers a new planet with water. They notice that there is water in lakes rivers, and oceans, but no clo
SVETLANKA909090 [29]

Which statement best explains the state of the water cycle on this newly discovered planet?

A. The water is gathered in lakes or oceans or frozen in snow and ice.

B. The water is trapped as water vapor in the atmosphere and clouds.

C. There is constant rain or snow falling on the planet's surface.

D. Water is frozen underground instead of flowing on the surface.

Complete answer:

Water is frozen underground instead of flowing on the surface. Thus, the correct option is D.

The water cycle can be broken down into three parts, as follows:

  1. Evaporation
  2. Condensation
  3. Precipitation

Evaporation: When the sun's heat drives water from oceans, lakes, streams, ice, and soils to rise into the air and transform into water vapour, this is known as evaporation (gas). Clouds form when water vapour droplets combine.

According to the first statement, water may be collected in lakes or oceans, or frozen in snow and ice. Evaporation occurs when water is collected in lakes or seas and exposed to high enough surface temperatures. Also, if water is frozen or in snow, the rate of evaporation will be significantly reduced, although it may still occur provided individual molecules carry sufficient heat. This statement provides some explanations for why we may not see evaporation, but it is not the best available to describe the water cycle on this planet.

Because of the available answers, this one best explains the state of the water cycle on this planet because it provides the most likely scenario for which astronomers would not be able to observe evaporation, given that it would occur on a small scale due to the extremely low temperatures and would take place underground, it would appear that evaporation is not working.

Which of the following is not a function of astrocytes?
VLD [36.1K]

The correct answer is: E) provide the defense for the CNS

Astrocytes are star-shaped cells found in central nervous system (brain and spinal cord) .Some of their functions include:

• Support of neurons by supporting endothelilal cell of blood–brain barrier,

• Provide nutrients to neurons

• Maintain ion balance and thus controlchemical environment around neurons

• Repair of injuries in the brain

• the secretion or absorption of neural transmitters…

The cells that provide the defense for the CNS are called microglia. Those cells are also glial cells, derived from macrophages and thus, part of active immune defense.
