6 0

Answer:

C. Systemic arterioles respond to a decrease in PO₂ by dilating, but pulmonary arterioles constrict in response to decreased PO₂.

Explanation:

In the arterioles, vasoconstriction is a response to high oxygen while vasodilation is a response to carbon dioxide and low pH. However, in the pulmonary arterioles, vasoconstriction occurs as a response to low oxygen and this mechanism is called hypoxic pulmonary vasoconstriction (HPV).

Naddik [55]

Answer:

The Monterey pine and the Bishop's pine inhabit some of the same areas of central California. The Monterey pine releases pollen in February, while the Bishop's pine does so in April. This is an example of <u>temporal</u> isolation.

<u>For example:</u> Northern america leapord frog mates in April and North America Bullfrog mates in july.

As in the given scenario, reproductive isolation is occuring in which two species (Monterey pine and Bishop's pine) are reproducing (producing pollens) at two separate times(February and April). Hence it is an example of temporal isolation.

Kruka [31]

The items needed to complete a circuit include the following:

  • Wire
  • Battery
  • Load
  • Switch

<h3>Functions of the parts of a Circuit.</h3>

The wire helps in the distribution of the electric current from the power

source in order to ensure it gets to the load.

The battery contains compounds which is responsible for providing the

energy required to power up the load.

The load could be a bulb, fan etc and is the final destination of the electric

current. The electric current powers up the load and makes it functional.

The switch helps to regulate the flow of electric current and has an 'on and

off button' to prevent energy wastage when not in use.
