Answer:
b
Explanation:
Parathyroid glands release a hormone to regulate calcium levels in the bloodstream the regulation of calcium levels in the blood.
Explanations:
Endocrine glands are the gland that secret hormone directly into the blood for creating certain stimuli. Parathyroid glands produce parathyroid hormone, which plays a key role in the regulation of calcium levels in the blood. The parathyroid glands are two pairs of small, oval-shaped glands. They are located next to the two thyroid gland lobes in the neck. Each gland is usually about the size of a pea.
functions:
Release of calcium by bones into the bloodstreamAbsorption of calcium from food by the intestinesConservation of calcium by the kidneysStimulates cells in the kidney to transform weaker forms of vitamin D into the form that is strongest at absorbing calcium from the intestines

The nervous system and the muscle system respond to stimuli to produce motion. The movements of
muscles are mostly voluntary. Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the
.
The nervous system and muscular system respond to stimuli to produce movement.
What is nervous impulse?
The nerve impulse corresponds to an electrical current that propagates through neurons, thanks to a process of membrane depolarization. This depolarization process occurs through stimuli and its function is to transmit certain information to other cells (nervous, muscular or glandular).
With this information, we can conclude that the nervous system and muscular system respond to stimuli to produce movement.

The same number of water molecules inside and outside of the cell
No water inside or outside of the cell
A hypertonic solution has:
Fewer water molecules outside the cell than are inside the cell. Thus, option "A" is correct.
What is hypertonic solution?The cell is in a hypertonic solution because it lost water through osmosis and shrunk.A hypertonic solution contains more solute molecules compared to solvent molecules while the hypotonic solution has more solvent molecules than solute molecules.When a plant cell is placed in a hypertonic solution it loses water through osmosis and shrinks.An animal cell placed in a hypotonic solution absorbs water through osmosis, increases in size and then bursts. Plant cell, on the other hand, does not burst when placed in a hypotonic solution as it contains a cellulose cell wall.Thus, option "A" is correct.

How is sucrose moved in sink?
The sucrose moved in sink by active transport.
What is active transport?Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.
In this case, the sucrose moves from companion cells in sink elements by active transport. This reduces the water potential of the sink element by osmosis, which increases the hydrostatic pressure.

Transmit Absorb Frequency Light Energy Reflection Transparent
(image attached)
thank you!! WILL GIVE BRAINLIEST!!
Answer:
Transmit - cause (something) to pass on from one place or person to another.
Absorb - take in or soak up (energy or a liquid or other substance) by chemical or physical action.
Frequency - the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
Light Energy - Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes. Light is defined as a form of electromagnetic radiation emitted by hot objects like lasers, bulbs, and the sun.
Reflection - the throwing back by a body or surface of light, heat, or sound without absorbing it.
Transparent - (of a material or article) allowing light to pass through so that objects behind can be distinctly seen.
Answer:
In the photo to the left, we can see a red tomato. This tomato appears red because of how it is interacting with the light energy it is receiving. It is reflecting red, and absorbing all other colors: orange, yellow, green, blue, and violet. In this depiction, you can see an entire rainbow of colors going into the apple and only red coming/bouncing (reflecting) back off. You can also see the green of the stem, which is colored in the same way. It absorbs certain frequencies of light--all other colors of light than green--and reflects certain frequencies of light, green light.
In this image, we are able to see the apple and stem because the air/medium that we are seeing this image through is transparent. If the surroundings were opaque, we wouldn’t see red at all (all colors would be blocked if light is blocked).
Another transparent factor in this image are light waves. Actual lightwaves (unless they are being refracted in such a way that they are being spread out--like a laser beam hitting a spray of water mist) are transparent.
You wouldn’t be able to see the [red] lightwaves bouncing off, you would only see the red of the apple. When light is being refracted by a different translucent material--such as glass, plastic, and water--that material is also transmitting the light, it is passing on the light wave. This is when refraction/the bending of light due to a change in media occurs.
