Why does the moon appear to change its shape as seen from earth?
Answers
Different parts of the sun lit moon become visible as the moon revolves around earth
This happens because as the moon orbits earth the sun will project light towards it and the reason it seems to glow is because of the reflected light since the moon is white it reflects more light. Think of it as a day and night cycle except it’s on the moon when it becomes night on earth the part of earth facing towards the sun will be lit aka day/morning/afternoon etc
The part of the earth facing away will be dark aka night/midnight/etc.

Put the following in order to show the path that sound travels through the ear.
mechanical energy is changed to electrochemical energy
sound strikes the eardrum
impulse is sent to by the auditory nerve to the brain
vibrations travel through the malleus, incus, and stapes
sound waves get to oval window
outer ear funnels and focuses sound
hair cells in the organ of Corti detect the wave
Answers
Answer:
Explanation:To show the path that sound travels through the ear, the following steps can be arranged in order:
1. Outer ear funnels and focuses sound: Sound waves enter the ear through the outer ear, which includes the pinna and ear canal. The shape of the outer ear helps to gather and direct sound waves towards the middle ear.
2. Sound strikes the eardrum: Sound waves reach the eardrum, also known as the tympanic membrane, and cause it to vibrate. The eardrum separates the outer ear from the middle ear.
3. Vibrations travel through the malleus, incus, and stapes: The vibrating eardrum transfers its energy to three small bones in the middle ear called the ossicles. These bones, known as the malleus, incus, and stapes, amplify and transmit the vibrations to the inner ear.
4. Sound waves get to oval window: The stapes bone in the middle ear transmits the vibrations to the oval window, which is a flexible membrane located in the inner ear. The oval window acts as the entrance to the fluid-filled cochlea.
5. Hair cells in the organ of Corti detect the wave: Within the cochlea, the vibrations of the fluid cause the movement of specialized cells called hair cells in the organ of Corti. These hair cells convert the mechanical energy of the sound waves into electrochemical signals.
6. Mechanical energy is changed to electrochemical energy: As the hair cells in the organ of Corti are stimulated, they generate electrochemical signals in response to the sound vibrations. These signals represent the sound information and are sent to the auditory nerve.
7. Impulse is sent by the auditory nerve to the brain: The electrochemical signals from the hair cells are transmitted to the brain via the auditory nerve. The brain then processes and interprets these signals as sound, allowing us to perceive and understand the sound we heard.
By following these steps in order, we can understand the path that sound takes through the ear, from the outer ear to the inner ear and ultimately to the brain for perception.
Explain the following functions of a Lily Flower:
-Chloroplast
-Photosynthisis
-Seeds
-Roots
(Please only answer if you know what it is.)
I will give brainlest to the correct answer!
Answers
Answer:
Chloroplast.
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids, ...
Phtosynyhsis.
The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process
Seeds.
Seeds serve several functions for the plants that produce them. Key among these functions are nourishment of the embryo, dispersal to a new location, and dormancy during unfavorable conditions.
Roots.
Root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

Vitamins and minerals are essential for healthy growth and development in children. A variety of foods from each of the five food groups can provide vitamins and minerals to children.
In contrast to other dietary components known as macronutrients (such as fats, carbohydrates, and proteins), which are the compounds utilized in the reactions regulated by the vitamins, the vitamins regulate reactions that occur in metabolism.

Answer: both are changes of state and both are changes of state
Explanation:
.
The two changes like the Saliva breaking down a piece of bread and a penny tarnishing involves chemical change. Thus, the correct option for this question is B.
What do you mean by Chemical change?A Chemical change may be defined as a type of change that significantly involves the production of new substances from old ones by combining each other with different properties.
The action of saliva is stimulated by the action of the enzyme salivary amylase which hydrolyzed the starch into maltose, a disaccharide. A penny tarnishing involves the dissolution of copper oxide in a mixture of weak acid and table salt.
Therefore, the given two changes have in common that both are chemical changes. Thus, the correct option for this question is B.
