Basalt, formed from magma, contains iron-rich minerals. Why is basalt important?A. Iron is magnetic and it triggers the reversal of Earth's magnetic field.
B. Iron is rich in nutrients and makes the soil easily identifiable.
C. Iron is magnetic and records the orientation and direction of Earth's magnetic field.

Answers

Answer 1

Answer: I think the correct answer from the choices listed above is option C. Basalt is important since it contains iron-rich minerals that are magnetic and used to record the orientation and direction of Earth's magnetic field. Hope this answers the question. Have a nice day.

Answer 2

Answer:

Iron is magnetic and records the orientation and direction of Earth's magnetic field.

Mitosis results in the formation of how many cells; meiosis results in the formation of how many cells? see concept 13.3 (page 262)

Answers

Mitosis results in the formation of two diploid cells while Meiosis results to the formation of four haploid cells. Mitosis is a process that takes place in the somatic cells; a cell that has doubled its genetic material divides to produce two diploid daughter cells while meiosis is a process that take place in the gamete cells where a doubled cell undergoes two rounds of division producing four haploid cells.

When a muscle is unable to respond to stimuli temporarily, it is in which of the following periods? When a muscle is unable to respond to stimuli temporarily, it is in which of the following periods? latent period fatigue period relaxation period refractory period

Answers

Answer:

Refractory period

Explanation:

When two stimuli are applied one after another intermediately, muscles contract in response to the first stimuli. Once a muscle fiber receives stimulation to contract, it loses its excitability temporarily and cannot respond for a time. This period when the muscle loses its excitability is called refractory period.

Different types of muscle fibers have different duration of refractory period. The refractory period of skeletal muscle is shorter than that of cardiac muscle. During an absolute refractory period, the activation gates of voltage-gated Na+ channels are open and the channels are inactivating while the voltage-gated K+ channels are open.
