Darwin's experiments are just one way to study phototropism. A student wants to investigate the effects of phototropism in bean plants. She places a light source directly above one plant, at a forty‐five degree angle to another, and at a ninety‐degree angle from the third.
What is her independent variable?
What is a hypothesis she might write for her experiment?
Answers
Answer:
Her independent variable is the light source and her hypothesis is what YOU think might happen
Answer:
The independent variable is what is being changed or altered in the experiment (light position), the dependant variable is what is altered or changed by the independent variable (plant).
Explanation:
Consider what is being changed in this experiment to investigate the effects? The plant itself is not changed by the experiment but the positioning of the light source is. That is your independent variable. The plant may change as a result of the independent variable but isn't being altered or changed as part of the method (dependent).
What is a hypothesis she might write?
Consider a hypothesis as a prediction. Researchers come up with their hypothesis based on the information they already know. So to write your hypothesis think about what you already know about phototropism. What do you think will happen to the plant in relation to the positioning of the lamp? Will the plant not move? Will it bend or move to face the lamp?
Hope this helps.
Is better for an ecosystem to have high or low species abundance?
Answers
Answer:
There should equilibrium state in the ecosystem in case of number of species, if there will be high species abundance there would be higher rate of competition in between the species also the predation can be easily seen in such ecosystem. On the other hand if the species abundance is low then the competition between the species and predation can not be seen.Which statement best describes the function of nucleic acids?
A. Stores genetic information and helps to make proteins
B. Increases the rate of chemical reactions
C. Stimulates metabolism in all body cells
D
Activates secretion of the body's hormones
Answers
Answer:
A. stores genetic info and helps make proteins.
Explanation:
Nucleic acids are DNA and RNA.
The statement that best describes the function of nucleic acid is stored genetic information and helps to make proteins. The correct option is A.
What is nucleic acid?Nucleic acid is a macromolecule. Nucleic acid is made up of nucleotides. The composition of nucleotides is a 5-carbon sugar, a phosphate group, and a nitrogenous base.
Nucleic acid is the main component of the genetic material of the living organism. They are DNA and RNA. DNA is the main genetic material of animals and plants, and RNA is found in some bacteria and some plants.
DNA and RNA store the genetic information of the organism. As this, nucleic acid also contains genetic material. This genetic information is used in synthesizing proteins.
Thus, the correct option is A. Stores genetic information and helps to make proteins.

All eukaryotic cells contain at least one Golgi complex, typically located in the cytoplasm and near the endoplasmic reticulum.
Which of the following best describes a process that occurs within the Golgi complex?
Answers
Answer: Enzymatic modification of newly synthesized integral membrane proteins
Explanation: got it right for AP Bio.
The correct answer that describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.
Once protein is synthesized, they undergo folding and repackaging within the endoplasmic reticulum before they are transported to the Golgi apparatus/complex.
Within the Golgi complex, the protein is modified enzymatically and encased in vesicles. It is then transported to the cell membrane where they are utilized as integral protein.
So, basically, the statement that best describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.

Facilitated diffusion is a type of passive transport
Hope this helps!!!!
Classifying each type of cell transport :
Diffusion : Passive transport Endocytosis : Active transportExocytosis : Active transportFacilitated diffusion : Passive transport Osmosis : Passive transportA passive transport system is the movement of solute in solution across regions of different electrochemical potentials on either side of a cell membrane ( i.e. from higher concentration to lower concentration) examples include : diffusion, osmosis and facilitated diffusion. while
Active transport system is the movement of molecules across a cell membrane by the application of cellular energy and not the difference in electrochemical potential. examples include Endocytosis and exocytosis
Hence we can conclude that Classifying each type of cell transport :Diffusion ; Passive transport. Endocytosis : Active transport. Exocytosis : Active transport. Facilitated diffusion : Passive transport. Osmosis : Passive transport .

Answers
Answer:
The correct answer is - contact metamorphism.
Explanation:
Contact metamorphism is one of the two metamorphism processes which takes place when the pre-existing rock is introduced to a great amount of heat which affects it by an intrusion of magma. It is known as a low pressurized, high-temperature type of metamorphism.
An example of this type of metamorphism which experiences recrystallization in the rock and forms a metamorphic marble that is formed by the recrystallization and mineral reaction of the limestone.
