This question lacks options, the options are:
A). Roots would grow up out of the pot and then down towards the light.
B). The plant stem would grow up and roots would grow down.
C). The plant would start to bend over and grow downwards toward the light.
D). The plant would wilt and die.
The answer is C
Explanation:
This question is describing an experiment conducted to test the effect of LIGHT on plants movement, a phenomenon called PHOTOTROPISM. Phototropism is the response of a plant towards a light source.
According to this experiment, a light source is placed below a plant and observed over a three-week time period. At the end of three weeks, the experimenter will observe that "the plant would start to bend over and grow downwards toward the light" because the plants strictly require light to photosynthesize and grow, hence, it will respond by moving in the direction of the available light source.
The growth and the development of the plant parts towards the stimuli source are called tropism. The plant will bend downwards towards the light source.
What is phototropism?Phototropism is the phenomenon in which the parts of the organisms turns and starts growing in the direction of light sources like the sun or artificial light that acts as the external stimuli.
In the experiment, the light source acts as stimuli for the plant and the plant growth is the response. In the experiment the light source is kept down and acts as a stimulus for the plant, in return, the plant bends over and grows in the downwards direction.
Therefore, option C. plant will bend over and grow downwards.

How the
immune system works, explain why injecting an
antigen from a pathogen would help our immune
system create "memory" of the infection but not
cause the disease.
Answer:
Our immune system produces antibodies against that antigen of pathogen.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.

-self-concept
-self motivation
-volunteer
-self-image
-Adolescents
Answer:
Self-concept is the set of ideas that make up the image that each person has about himself, that is, it is the opinion that an individual forges about himself. That sentence carries a certain value judgment. Self-concept: set of elements that a person uses to describe himself. Self-motivation is giving the reasons, the drive, the enthusiasm and the interest that provoke a specific action or a certain behavior. Volunteer is the person who, by his own choice, dedicates part of a part of his time to solidary, altruistic action, without receiving remuneration in return. The stage that comes after childhood and that ranges from puberty to the full development of the body is known as adolescence. Self-image is the value we have in relation to ourselves.
Explanation:
Self-concept: set of elements that a person uses to describe himself. The ability to motivate yourself is what is known as self-motivation. This is an important skill, as it encourages people to continue progressing even in the face of setbacks, to seize opportunities and to show commitment to what they want to achieve. Volunteer is that person who joins an organization in a free way to help altruistically in various social activities.

All of the following can take material into cells except
O active transport
O exocytosis
O endocytosis
O passive transport
Answer:
The correct answer is - exocytosis.
Explanation:
All of the given options of the transport mechanism are the transport of the substances either into the cell or out of the cell or both. Active transport is the transport mechanism that involves the transports of substances from the lower concentration region to the higher concentration region and utilize energy.
Endocytosis and exocytosis are the forms of active transport, however, endocytosis involves taking material into the cell and exocytosis out of the cell. Exocytosis is the form of active transport as it requires energy to moving materials from within a cell to the exterior of the cell.
How does population growth differ between developing countries and developed countries? What might account for these differences?

Use the following terms: Natural Selection, Variation, Mutation, Adaptation, Overproduction, Descent with Modification, Evolution, Population, Species, Heritability, and Fitness and show the relationship between them that lead to the result, Evolution.
Answer:
Variations in species led to evolution. Some species have desirable traits that are beneficial to their survival. Some species have undesirable traits that are not beneficial to their survival. E.g. peppered moths are not easily seen by predators because they camouflage with the bark, black moths are easily seen by predators so they are eaten. In the example mentioned, the peppered moths have a beneficial trait, this is also known as fitness, because the organism is fit for survival, unlike the black moths. Overtime the population of black moths decreases because they are not fit for survival, therefore the black moths cannot reproduce offspring that also have black wings. However, the population of peppered moths increases, because the peppered moths are able to reproduce offspring. Those offspring inherit their parents' traits, which make them have peppered wings too.
