3 0

Answer:

The derived unit of pressure is newton per metre square (Pa). It is a derived unit because it's obtained by adding two or base quantities.

The symbol is Pa and the expression in terms of SI base units is m-¹kgs-²

Climate is primarily determined by the interaction of the air and _____. oceans winds lithosphere plants
Mariulka [41]

Answer: Oceans

Explanation:

Climate is primarily determined by the interaction between air and ocean. The warm wind circulate and makes the temperature feasible for life.

Oceans heat the air above it and it circulates from the equator region to the polar region to make the temperature optimum. The circulation of air due to ocean leads to climate change.

hence, these two factors are responsible for the climate of a region.

During depolarization, which of the following statements about voltage-gated ion channels is TRUE
Wewaii [24]

Answer:

In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.

Explanation:

Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.

  • Na⁺  is a predominantly extracellular cation.
  • K⁺ has a high intracellular concentration.

This distribution occurs when the membrane potential is at rest, with a negative intracellular value.

Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.

While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.

Describe the main difference between primary and secondary succession.
frosja888 [35]

Answer:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lack soil.

Secondary succession is one of the two types of ecological succession of a plant's life. It is the process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.

Explanation:

Primary succession takes time for completion around 1000 years, whereas secondary succession area takes 200 years for completion. In primary succession, there is a lack of soil and humus for the sustaining of life whereas, in secondary succession, soil and humus are present with some organisms.

A Secondary succession can take a few hundred years.
