Answer:
c. The dependent variable is the plant heights; the independent variable is the room temperature
Explanation:
Here, the effect of room temperature on the height of plants is being studied. The amount of light the plants get is equal the only differentiating factor is the room temperature.
In an experiment to determine the inter relationship between two variables on variable is changed and the variable which changes with respect to the first variable is studied.
The variable which is changed inpendently i.e., it does not change with respect to another variable is called the independent variable.
The variable which changes with respect to the independent variable is called the dependent variable.
Hence, the plant height is the dependent variable and the room temperature is the independent variable.
Answer:
a new dimension of an existing behavior
Explanation:
behavior is simply any activity of an organism, individuals that can usually be observed or measured. Humans behaves in different ways and sometimes has a new way, style rather dimensions to their behavior that is already inherent in them.
Shaping behavior involvessystematically and differentially reinforcing successive process of approximations to an inherent behavior.
Behavioral shaping by skillful practitioner can shape known forms of behavior from responses that previouslybear little identity to the final product.

<span>To combat the threat of tropical diseases such as malaria
and yellow fever, the United States decided to use new measures to eradicate
the disease before the construction of the Panama Canal. Under the leadership of Colonel William
Crawford Gorgas, many changes were made.
When it was discovered that mosquitoes were the source of the disease,
Gorgas who was appointed as the head of hospital and sanitation, he made sure
that containers with stagnant water were removed because mosquitoes lay their
eggs there. He also built domestic water
systems to eliminate the need to collect rain water. Prophylactic Quinine was supplied to the
people in the area and fumigation and oiling of streams were launched. Those who were sick were quarantined and workers
would sleep in screened structures so that mosquitoes would not be able to bite
them. These programs resulted in the
successful elimination of tropical diseases in the area and the health of
workers improved.</span>
Answer: "Long-term potentiation, or LTP, is a process where communication across the synapse __between neurons strengthens___ the connection, which makes further communication __easier___."
Explanation: Long term potentiation is described as process whereby communication across the synapse between neurons strengthens the connection, making further communication easier. This is based on recent patterns of synaptic activity that produces long-lasting increase in signal transmission between two neurons. The LTP in the hippocampus is regulated by the activity of the neurotransmitter: glutamate at NMDA receptors, a necessary component for memory formation.
