The unemployment rate went as high as 24.9% during the great depression.
The researchers present unshelled northern and southern periwinkles to northern and southern crabs in the second experiment to test if either population of periwinkles was unpalatable to either population of crabs.
Answer: Option D
<u>Explanation:</u>
The researchers picked up crabs and periwinkles from the northern and the southern location of Gulf of Maine. Then an individual crab was inserted into hutch companied with 8 size variable periwinkles. Following four set-ups were organized, where crabs involved were of both gender but not size variable and these set-ups were analyzed 12-14 times:
- Northern crab and periwinkles
- Southern crab and periwinkles
- Northern crab and southern periwinkles
- Southern crab and northern periwinkles
After three days of experiment conclusion drawn was: southern crab killed more number of northern periwinkles when compared with rest three set-ups. While second is northern crab and northern periwinkles, third is southern crab and periwinkles and fourth is northern crab and southern periwinkles.
Now, same set-ups as above was organized but with unshelled northern and southern periwinkles and conclusion researchers found that crabs catered themselves with all unshelled periwinkles within 1 hour to test if either periwinkles population was unpalatable to either crabs population.
East African countries are very close to the equator, but do not have a tropical forest climate due to the fact that there has been significant deforestation in the region, due to population growth, logging and agriculture.
<h3 /><h3>What is the importance of environmental preservation?</h3>
Sustainability allows for the conscious use of scarce natural resources, increasing the quality of life for current and future generations, in addition to protecting rivers, forests and seas. Environmental degradation generates irreversible problems that impact the lives and health of individuals as a whole.
Therefore, it is essential that sustainability is promoted in society, through organizational practices of CSR, public policies and public awareness of the need to protect environmental resources.

Answer:
Receiver.
Explanation:
The communication process is a two-way process where a message is transmitted from one subject to another one or to a group of people.
It consists of several components:
- The sender is the one who sends the message and that needs to encode the message from her thoughts or ideas to be transformed into something that can be sent and received, for example, words.
- A channel of communication, it has to be selected and it’s how the message is sent. Some of the channel of communications are speaking, writing, videos, audios and even body language.
- The receiver, is the person who the message is meant to be transmitted to, the receiver needs to decode the message, which means he/she needs to process the message and understand it. This is why the message needs to be clear and in a way that both parts (the sender and receiver understand), the message can fail if for example, the two parts speak different languages.
- There is a last component that may or may not happen, that happens when the receiver becomes the sender and gives a feedback, and the roles of both change, the receiver becomes the sender and the sender becomes the receiver.
