Answer:
Explanation:
REFRACTION is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows
REFLECTION is when light bounces off an object. ... For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection

Write a list of the words that directly intervene in the water cycle, that is, that are part of the different states that present the water cycle.
Answers
Answer:
Evaporation, transpiration, condensation, precipitation, and runoff.
Explanation:
Evaporation, transpiration, condensation, precipitation, and runoff are the words that directly intervene in the water cycle. The evaporation occurs in the water bodies when the water is heated with the help of solar radiation whereas transpiration occurs from the plant body. When this water vapors goes in the atmosphere, they form clouds by condensation of water molecules and as a result precipitation occurs. Some rain water is absorbed by the soil while the remaining run-off on the surface in the form of streams, lakes and rivers etc.
Which organism is most likely to be found in a deepsea trench?Immersive Reader (1 Point) a. Archaebacteria b. Eubacteria c. Protist d. Fungus
Answers
The organism that is most likely to be found in a deep sea trench is Archaebacteria. The correct option is a.
What is Archaebacteria?The domain of single-celled organisms is called Archaea. These microbes are prokaryotes because they lack cell nuclei.
The term "archaebacteria," which was used to describe archaea when they were first categorized as bacteria, is no longer in common usage.
The group of microorganisms known as archaebacteria is frequently referred to as a kingdom. They are thought to be an ancient form of life that originated independently from bacteria and blue-green algae.
Archaea are well known for their preference for living in harsh conditions.
There is likely life there, and that life is likely an archaeal species whether it is extremely hot (hotter than 100° Celsius), freezing, acidic, alkaline, salty, deep in the ocean, or even assaulted by gamma or UV radiation.
Thus, the correct option is a.

Explain the process of evaporation.
Answers
Answer:
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. ... Heat from the sun, or solar energy, powers the evaporation process.
The sun heats the ocean's surface and the air during the day, causing water molecules to evaporate.
A liquid turning into a gas is evaporation. It is how water gets from the surface of the Earth to the atmosphere.
Latent heat is a form of energy held in the evaporated water when it evaporates and cools.
Evaporation plays a significant role in the energy exchange that results in atmospheric motion, affecting weather and climate in the Earth-atmosphere system.
The particles with the highest kinetic energy are the first to evaporate from a liquid.
Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

The proteins that comprise the thick and thin filaments are contractile proteins that generate the contractile force of the muscle. What are the other 2 groups of proteins found in muscle and what are their functions?
Answers
Answer:
The other 2 groups of proteins found in muscle are: soluble or sarcoplasmic proteins, extractable with water or diluted saline solutions and are: myoglobin, enzymes and insoluble or connective tissue and organelle proteins.
Explanation:
The primary components of skeletal muscle fibrils are myosin and actin, as well as tropomyosin and troponin associated with actin. Other muscle proteins are essential for regulating the precise spacing, attachment and alignment of myofilaments. Proteins of the muscle are divided into three groups: contractile apparatus or myofibrillar proteins, extractable in its majority with concentrated saline solutions and are: myosin, actin , tropomyosin, troponin, soluble or sarcoplasmic proteins and insoluble or connective tissue and organelle proteins. Soluble proteins make up 25-30% of the total protein in muscle tissue. It consists of about 50 components, essentially enzymes and myoglobin. The high viscosity of the sarcoplasm is due to the high concentration of dissolved proteins, which reaches 20-30%. Myoglobin traps oxygen inside muscle cells so that they produce enough energy for contraction. Sarcoplasm primarily contains the enzymes necessary for glycolysis and the pentose-phosphate cycle. Insoluble proteins make up most of the protein material insoluble both in water and in saline solutions that is a constituent of connective tissue. To it must be added the membrane component and the insoluble portion of the contractile apparatus. Connective tissue contains various types of cells. Also characteristic of this tissue is the large amount of intercellular substance, produced by those same cells, composed of amorphous material (carbohydrates, lipids, proteins) and collagen fibers included in it. Collagen helps give elasticity and strength to muscles.
Involuntary muscle includes _________.
A) skeletal muscle only
B) smooth muscle only
C) smooth muscle and cardiac muscle only
D) smooth muscle, cardiac muscle, and some skeletal muscle
Answers
Answer:
answer part d
Explanation:
smooth muscle, cardiac muscle, and some skeletal muscle
Involuntary muscle includes smooth muscle and cardiac muscle only.
What is meant by involuntary muscle?
Muscles that contract or move voluntarily are known as involuntary muscles. Involuntary muscle action is controlled by the autonomic nervous system. The internal organs or viscera that exhibit consistent, gradual contractions and involuntary motions are typically connected with these muscles. The heart is one such uncontrollable muscle.The autonomic nervous system, hormones, and local variables can cause the involuntary activity of the majority of involuntary muscles by neural stimulation. But in other muscles, such as the walls of visceral organs, extending the muscle can cause an involuntary muscle contraction.
Therefore, option (C) is correct.
