Answer:
A control variable is the variable in the experiment that does not change.
Explanation:
If you are testing how seeds grow in different types of water, and you add 1tbps of salt to one pot of water with the plant, and then added 2tbps to another pot of water with the plant. The control variable in this experiment would be the water with no salt because it was not altered.
FYI I did not pull from google. Good luck!

Do different color leaves use white light differently for photosynthesis?
Answer:
Answer 4: Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red (therefore, blue and red are useful for photosynthesis, but green isn't).
Answer:
In the explanation. :)
Explanation:
Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red meaning therefore, blue and red are useful for photosynthesis, but green isn't.)

A volcano erupts, and lava flows down a mountainside. Which statement best describes this eruption?
This is a quiet eruption caused by low-viscosity magma.
This is an explosive eruption caused by high-viscosity magma.
This is a quiet eruption with lava spewing out violently.
O This is an explosive eruption during which gases bubble out gently.
Answer:
The Answer To This Question Is A. This is a quiet eruption caused by low-viscosity magma.
Explanation:
When A Volcano Erupts And Lava Is Dripping From The Side Of The Volcano It Means That It Is A Quiet Eruption Caused By Low Viscosity Magma, The Frequency Of Eruption Are Related To The Viscosity And Amount of Dissolved Gas In The Magma
Hope I Helped!

How does ultraviolet radiation harm living things?
Answer:
Ultraviolet (UV) photons harm the DNA molecules of living organisms in different ways. In one common damage event, adjacent bases bond with each other, instead of across the “ladder.” This makes a bulge, and the distorted DNA molecule does not function properly.
Explanation:
The deforestation of a wooded area increases erosion, resulting in increased sediment at the bottom of a nearby river. This leads to increased flooding in the area. Which of the following terms best defines this chain of events? A) uniformitarianism B) a positive feedback loop C) a negative feedback loop D) environmental unity
Answer:
D
Explanation:
Environmental unity means that everything is connected to each other and affects each other. Here, the wooded area affects the river, which affects the flooding.

How does the climate change affect human population
Answer:
Climate change effects such as hunger, poverty and diseases like diarrhea and malaria, disproportionately impact children; about 90 percent of malaria and diarrhea deaths are among young children. Children are also 14–44 percent more likely to die from environmental factors, again leaving them the most vulnerable.
what is kwaishokor and its causes?
Answer/Explanation:
Kwashiorkor is a severe form of malnutrition that is caused by an extreme protein deficiency. It is rare is developed countries, but more commnon in areas where food supply and hygeiene are issues. It is much more common in children than in adults.
It causes swelling under the skin due to the retention of fluids causing a prominent 'pot belly'. It also shows reduced muscle mass, skin problems, infections, brittle hair and nails. It can be fatal.
A sarcomere is...
A. an organ
B. a protein filament or fiber
C. the basic contractile unit of muscle contraction
D.an organelle
Answer:
C, basic contractile unit of muscle fiber.
Explanation:
If you read the definition of sarcomere, this is what it says: "A sarcomere (Greek σάρξ sarx "flesh", μέρος meros "part") is the complicated unit of striated muscle tissue. It is the repeating unit between two Z lines. Skeletal muscles are composed of tubular muscle cells (myocytes called muscle fibers or myofibers) which are formed in a process known as myogenesis."

Answer:
The theory of Continental Drift suggest that hundreds of years ago all the continents were one big continent called Pangea. Soon these contintents split up created the places that we live today. This theory was introduced by Alfred Wegener. His colleges thought he was crazy, but later studies proved his impossible theory to be true. By the process of "sea floor spreading" the continents were then ripped apart and drifted to where they are today.

Explanation:
Jorge is conducting an comparative experiment where he is comparing the heights of adults who grew up taking a certain vitamin and adults who did not. He finds that those who took vitamins are, on average, 2 cm taller. What is a major limitation of his experiment?
Answer:
Major limitation of Jorge's experiment are -:
Vast amounts of data can be obtained.He does not prove definitively that a person is taller because of vitamins. No association between vitamins and height can be seen.Explanation:
ABOUT VITAMINS -:
A vitamin is an organic molecule that is an important micronutrient that an organism requires in limited amounts for the proper functioning of its metabolism (or a chemically closely connected group of molecules, i.e. vitamins). In the body, basic nutrients can not be synthesized in adequate amounts, either at all or not, and must therefore be ingested via a diet.
Hence, the major limitations of the experiment are mentioned above.
Rocks, as they are compressed, begin forming mountains above the Earth's surface when two continental plates converge. The continental crust increases in depth as the mountains grow above. The Himalayan Mountains formed at a convergent plate boundary in this manner. The rocks are smashed together causing them to __________ due to the intense heat and pressure from the colliding plates and eventually forming _____________ rock.
Answer:
recrystallize
metamorphic
Explanation:
Rock can simply be defined as that which is formed from the remainis of plant and animals which has undergone decay. It is said to be nature solid mixture of one or more minerals or organic matter.
metamorphic rock is one of th types of rock. It occurs or forms from an other already existing rock that is acted upon and change occurs to it as a rest of heat, pressure, or chemical reaction.The Himalayan Mountains is located in the asian.

Answer:
prophase-during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears
Metaphase-during which the chromosomes become attached to the spindle fibers.
Anaphase-which the chromosomes move away from one another to opposite poles of the spindle.
Telophase-in which the chromatids or chromosomes move to opposite ends of the cell and two Identical nuclei are formed.
