Why does sound bounce off of walls?
Answer:
Original sound waves are distorted by strong later-arriving reflections. Also, sound wave energy is really fast, about 1130 feet per second. A sound wave will bounce back and forth between these two walls about 60 times in one second. Sound travels so fast, it fills a room almost instantly.

How does earth's position in space affect water on earth?
Answer:
The Earth's position affects the water because the sunlight from the sun can impact the temperature of the water. It heats the water ethics and the land around it. When the Earth is facing the moon (nighttime), it cools the ocean creating a soft reaction.
Explanation:
While Earth orbits the sun, the planet is simultaneously spinning on an imaginary line called an axis that runs from the North Pole to the South Pole. It takes Earth 23.934 hours to complete a rotation on its axis and 365.26 days to complete an orbit around the sun.

Photosynthesis and cellular respiration form a cycle. A cycle is a sequence of events that repeats itself over and over again.
In your own words, explain how photosynthesis and cellular respiration form a cycle. Include details about the organisms that perform photosynthesis and cellular respiration, and the materials involved.
Your response should be at least 3 sentences long.
Answer:
Photosynthesis changes over carbon dioxide and water into oxygen and glucose. Glucose is utilized as food by the plant and oxygen is a result. Cell breath changes over oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are side-effects and ATP is energy that is changed from the cycle.

What are rotating air currents circulating around a vertical axis inside a supercell?
Answer:
Supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes. They are most common during the spring across the central United States when moderate-to-strong atmospheric wind fields, vertical wind shear (change in wind direction and/or speed with height), and instability are present. The degree and vertical distribution of moisture, instability, lift, and wind fields have a profound influence on convective storm type, including supercells, multicells (including squall lines and bow echoes), ordinary/pulse storms, or a combination of storm types. Once thunderstorms form, small/convective-scale interactions also influence storm type and evolution. There are variations of supercells, including "classic," "miniature," "high precipitation (HP)," and "low precipitation (LP)" storms. In general, however, the supercell class of storms is defined by a persistent rotating updraft (i.e., mesocyclone) which promotes storm organization, maintenance, and severity. More information concerning environmental conditions and the structure of classic and HP supercells is given below. WSR-88D Doppler radar imagery showing the evolution of some supercell events across Kentucky and south-central Indiana are available.

Does asexual reproduction involve the formation of gametes? Explain your answer
Asexual reproduction, the simplest and most primitive method of reproduction, involves a single parent and produces a clone, an organism that is genetically identical to the parent. Haploid gametes are not involved in asexual reproduction. A parent passes all of its genetic material to the next generation.
Answer:
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction, either from from a single cell or from a multicellular organism, inherit the genes of their single parent.

Answer:
An amoeba splits during binary fission into two separate cells.
Explanation:
The amoeba have identical offspring while all others have genetic variences
The scenarios of reproduction which is most likely to form uniform offspring is an amoeba splits during binary fission into two separate cells. Thus, the correct option is D.
What is Reproduction?Reproduction is the process of formation of new organisms which are similar to the parent organism or parent cell. Reproduction is the process which generally occurs through different methods in a living cell or an organism.
Reproduction is mainly of two types, which include Asexual and Sexual mode of reproduction. Asexual reproduction is the reproduction where only one organism is involved in the process and it does not need the formation of gametes or the sex cells and sexual reproduction results into the formation of organisms through the fusion of gametes from two different organisms.
An example of asexual reproduction is an amoeba which splits through the binary fission into two separate new daughter cells.
Therefore, the correct option is D.
