A. Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.
Answer:
This question is incomplete, the complete part is: What is the independent variable in this experiment? A) The plant species B) The amount of water that each plant gets C) The amount of time D) The different types of light the plants were put under.
The answer is D
Explanation:
In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.
In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light. Hence, the INDEPENDENT VARIABLE is the DIFFERENT TYPES OF LIGHT THE PLANT WERE PUT UNDER.

restriction enzymes cut DNA at totally random places. true of false?
Answer:
False
Explanation:
Restriction enzymes, also called restriction endonucleases, are enzymes found in bacteria that cut DNA. They recognise target sequences and cut DNA at or near these sequences. These sequences are called restriction sites.
They act as a defense mechanism against invading pathogens. However, they are routinely used in molecular biology labs to perform DNA technologies such as genetic engineering.

which type of succession occurs more rapidly what kind of disturbances could lead to this process
Answer:
Secondary Succession
Explanation:
Secondary Succession is faster than primary succession because soil is already there, and the soil usually contains many nutrients.
Examples: Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.
how are two processes from photorespiration related?
Answer:
Several physiological processes may be responsible for linking photorespiration and nitrogen assimilation. Photorespiration increases availability of NADH, which is required for the conversion of nitrate to nitrite.
Answer:
Two molecules are produced: a three-carbon compound, 3-PGA, and a two-carbon compound, phosphoglycolate. ... Photorespiration results in a loss of 3 fixed carbon atoms under these conditions, while the Calvin cycle results in a gain of 6 fixed carbon atoms.

What are the Layers of the Earth?
The Earth is made up of three different layers:
1.The Crust
2.The Mantle
3. The Core
1. The Crust
It is the outer layer of the earth which is mainly composed of solid rock of basalt and granite. There are two types of crust which are oceanic and continental.
2. The Mantle
The mantle lies beneath the crust and is up to 2900 km thick and consists of hot, dense, solid rock containing iron and magnesium. The crust and the upper part of the mantle divide the lithosphere into both major and minor plates.
3. The Core
The core is the center of the Earth made up of two parts: the liquid outer core and the solid inner core. The outer core is made of nickel, iron and molten rock.
Thus, the inner core is hotter than the surface of the sun. So, the correct option is (C).

What differentiates passive transport from active transport?
Answer:
Active Transport: Active transport pumps molecules through the cell membrane against the concentration gradient.
Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration.

WILL GIVE BRAINLIEST ANSWER. Which statement describes the relationship between breathing and cellular respiration in animals?
A. Carbon dioxide is inhaled and is a product of cellular respiration
B. Carbon dioxide is exhaled and is a product of cellular respiration
С. Carbon dioxide is exhaled and is a reactant of cellular respiration.
D. Cellular respiration and breathing are the same processes.
Answer:
B
Explanation:
The statement that describes the relationship between breathing and cellular respiration in animals is carbon dioxide is exhaled and is a product of cellular respiration. The correct option is B.
What is cellular respiration?Cellular respiration is a process of breakdown of food material and releasing energy into the blood. Oxygen is mixed with the food material and carbon dioxide is released out of the body.
Breathing is a process of taking in oxygen and taking out carbon dioxide from the body. Breathing is the first step of respiration, as oxygen is needed for the respiration process, which is done by breathing.
Carbon dioxide is a product of cellular respiration, and it is taken out of the body by breathing.
Thus, the correct option is B. Carbon dioxide is exhaled and is a product of cellular respiration.

Describe the famous experiment related to gravity that Galileo may have preformed. Include the results. Also, state whether the results support the law of gravity. Explain your answer.
Please help me please and thank you Id appreciate it very much.
Answer:
Galileo threw two balls from a tower's summit. They were both the same size and shape, yet one weighed 50 grams and the other weighed 500 grams. As a result, the two balls collided at precisely the same time. This finding backs up Newton's law of gravitation, which states that things with more mass will be subjected to a larger gravitational force. Because the 500-g ball has higher inertia, it takes more force to accelerate it. That force is provided by the stronger gravitational pull, and the two balls descend at the same rate.
Explanation:
One of the famous experiments often associated with Galileo Galilei is the experiment involving objects of different masses dropped from the Leaning Tower of Pisa. While there is some debate regarding whether Galileo actually conducted this specific experiment, it is often attributed to him for its conceptual importance.
According to the account, Galileo dropped two objects of different masses, such as a heavy cannonball and a lighter musket ball, from the top of the Leaning Tower of Pisa. The experiment aimed to determine whether objects of different masses would fall at different rates, as was commonly believed at the time. The expected result, based on the Aristotelian view prevailing during Galileo's time, would have been that the heavier object (the cannonball) would have fallen faster than the lighter one (the musket ball).

True or false: Euglena are examples of protists that can feed like an animal or use the energy of the sun to make food like a plant.
Answer:False
Explanation:
There are no man-eating plants or leaf-growing animals. The idea of an organism both photosynthesizing and hunting for food might seem strange, but this isn't science fiction. These organisms, examples of Euglena, are protists that can feed like an animal or use the energy of the sun to make food like a plant.
This statement is false. Euglena are not the examples of protists that can feed like an animal or use the energy of the sun to make food like a plant.
What are protists?A protist is any eukaryotic organism that is not an animal, plant, or fungus. While it is likely that protists share a common ancestor, the exclusion of other eukaryotes means that protists do not form a natural group, or clade.
Moreover, protists are any member of a group of diverse eukaryotic, predominantly unicellular microscopic organisms. They may share certain morphological and physiological characteristics with animals or plants or both.
Therefore, characteristics of protists: they are eukaryotic, which means they have a nucleus. Most have mitochondria. They can be parasites. They all prefer aquatic or moist environments.
