The cause of the phases of the moon is a cycle that is close to how long

Biology

AnnZ [28]3 years ago
7 0

Answer:

The lunar phases gradually change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around Earth and of Earth around the Sun shift. The Moon's rotation is tidally locked by Earth's gravity; therefore, most of the same lunar side always faces Earth.

Allushta [10]

False, I'd say. Mammals usually adapt based on environment. Now, I know predators are "apart" of the environment, but I don't think that'd be it. I'd bet more money on saying mammals evolve based on environment adaptation. Sorry if I didn't answer your question or if I didn't get my point across well.

emmasim [6.3K]
I can’t see your answer choices, but igneous rocks are made from cooled lava or magma. This is why these rocks are so brittle and grainy. I’ve attached a helpful image to better explain! Good luck!!!

The use of electronic instruments or other techniques to monitor and change subconscious activities, many of which are regulated
Wewaii [24]

The use of electronic instruments or other techniques to monitor and change subconscious activities, many of which are regulated by the autonomic nervous system, is called biofeedback.

<h3>What is biofeedback?</h3>

A mind-body approach known as biofeedback employs a variety of monitoring tools to give the body's physical functions, which are typically controlled by the body's automatic systems, conscious control. There are several kinds of biofeedback instruments that can be used to track the development of the activity and show the efficacy of the therapy as it is being administered.

The equipment that measures the following uses biofeedback the most frequently:

  • brain activity
  • respiration rate
  • blood pressure
  • heartbeat frequency and heartbeat variability
  • tension in muscles
  • electrification of the skin
  • skin temperature

Devices used to measure body change are:

  1. Electromyogram (EMG): To measure muscular tension, use this.
  2. Electrodermal activity (EDA): This measures variations in perspiration rate.
  3. Measures of finger pulses: These evaluate heart rate and blood pressure.
  4. Electroencephalogram (EEG): This is used to assess brain electrical activity.

How can this PLR (pupillary light reflex) help you determine whether the lesion is in the eye itself or elsewhere?
Contact [7]

Answer:

Pupillary light reflex refers to the contraction that the pupils present when they light up. In cases of injury to the optic nerve, when the eye where the injured optic nerve is illuminated, since it cannot conduct the stimulus to the brain, neither pupil closes.

Explanation:

Pupillary light reflex refers to the reaction that causes the pupil to close with light thanks to the contraction of the sphincter of the pupil and to open in the dark thanks to the relaxation of that muscle by not receiving any stimulus. A light stimulus reaches the eye and in the retina it is transformed, through a chemical reaction, into an electrical stimulus that will be transmitted through the optic nerve and the visual pathways to the brain. The visual cells of the retina, rods and cones, also act as light receptors that control the pupil's motor activity. Thus, pupil-motor thresholds to light follow the same spectral sensitivity deviations as visual thresholds, which are a function of the state of light adaptation of the retina.
