Think of a behavior that you have that you would like to change. How could you use behavior modification, specifically positive reinforcement, to change your behavior? What is your positive reinforcer?

Answers

Thus, positive reinforcement occurs when a behavior is encouraged by rewards. If a child enjoys candy and cleaning the room is the desired behavior, the candy is a positive reinforcer (reward) because it is something that is given or added when the behavior occurs. This makes the behavior more likely to recur.

True or False? When there is a solar eclipse, everyone in the world can see it
happening.





Answers

Answer:

i think it is true

Explanation:

Everyone in the contiguous United States, in fact, everyone in North America plus parts of South America, Africa, and Europe will see at least a partial solar eclipse, while the thin path of totality will pass through portions of 14 states.

Answer:

I belive it's false.

Explanation:

Acording to NASA's spaceplace website, Getting a chance to see a total solar eclipse is rare. The Moon's shadow on Earth isn't very big, so only a small portion of places on Earth will see it. ( which includes everyone in North America plus parts of South America, Africa, and Europe will see at least a partial solar eclipse, while the thin path of totality will pass through portions of 14 states)

Also Fun Fact:A total eclipse occurs when the dark silhouette of the Moon completely obscures the intensely bright light of the Sun, allowing the much fainter solar corona to be visible. During any one eclipse, totality occurs at best only in a narrow track on the surface of Earth. This narrow track is called the path of totality. (Credit: NASA )

Cedar waxwings are one species of bird that is adapted to
withstand our cold winters. Bird watchers in Barrie provide
cedar waxwings with seeds at birdfeeders during winter
months. wum
(a) Would the seeds alter the carrying capacity of the
ecosystem? Explain.
(b) Provide a hypothesis that explains why bird watchers have
noted an increase in the falcon population in recent years.

Answers

The process of adding or removing the food supply (seeds) in an ecosystem would alter its carrying capacity.

What do you mean by Carrying capacity?

Carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat to live. Every habitat has a fixed carrying capacity.

When the winter period comes, it decreases the number of seeds of cedar waxwings. At this time seeds undergo to dormant stage due to the freezing temperature of the winter, hence they can not be reproduced at this point.

In spite of this, offering seeds to the bird feeders during winter can be adequate for the reduction in the food supply of these birds.

It can assist them with sufficient food resources which allows them to get through the winter season. Hence, increasing the carrying capacity for the cedar waxwings in the ecosystem.

Therefore, it is well described above.
