(1) 9*4 - 4c = x
(2) 9*2 +2c = x

∴ 36 - 4c = 18 + 2c
18 - 4c = 2c
9 - 2c = c
9 = 3c
c = 3 mph

1. A psychologist conducted a study at her home during an annual activity of children wearing masks and
Musya8 [376]

Answer:

a) The dependent variable is defined as the variable that is being tested. The dependent variable here is the percentage of children who collected extra candy.

b) The data does not support the hypothesis 1 of the psychologist which states that the children would take more candy when they were alone. In the graph, percentage of children that took extra candy was higher when they were in group than when they were alone.

The data supports the hypothesis 2, which states that the children would take more candy when they were masked. From the graph, the percentage of children who took extra candy was higher when they were masked than when when they were unmasked.

c) The psychologist cannot generalize her findings to all children because she didn't use a random sampling procedure and she used children only from her neighborhood which doesn't represent the general population of children.

d) This study is not a naturalistic behaviour because the psychologist is dealing with subjects. She may also choose to manipulate the variables. Therefore we cannot call this study a naturalistic behaviour.

e) Modeling: This may play a role in the children's behaviour because the children may try to imitate what others did. The children may take extra candy because they saw others collecting extra candy.

Deindividuation: Here, the children's behaviour may be influenced by a feeling of anonymity. The children may take extra candy because they feel anonymous. Deinvuduated children feel anonymous due a feeling of loss of identity.

This explains why the percentage of chidren who took extra candy when in group was higher than that of the children who were alone.

Jonah and Jaycee are partners. Which of the following illustrates the concept of mutual agency?
vampirchik [111]

The option that illustrates the concept of mutual agency is D. Jonah signs a purchase agreement with a supplier while Jaycee agrees to hire a marketing firm to drum up business.

  • A Mutual agency simply means a legally binding relationship that is undertaken by business partners whereby each person can make a decision on behalf of the other person.

  • In such a case, whenever there's a decision to be taken maybe the purchase of goods or payment, a partner can make the decision without having to inform the other person.

  • Based on the illustrations above, since Jonah and Jaycee are partners, they can take decisions on behalf of each other.

In conclusion, Jonah can sign a purchase agreement with a supplier while Jaycee agrees to hire a marketing firm to drum up business.

Explain why the average cell size is similar in blue whale and in an earthworm.<br> Worth 20 points
Levart [38]

Answer: Limited Surface area - Volume ratio

Explanation:

Cells in various organisms usually have the same size be it a blue whale or an earthworm, a Human or a mouse or an Elephant and a squirrel. This is down to the way the cell is structure.

The Cell needs to absorb nutrients to survive while getting rid of waste material. For that to happen it needs an adequate surface area. The problem is that as the cell absorbs more nutrients thereby increasing in volume, this rise in volume occurs at a faster rate than the cell can increase its surface area so the surface area will keep shrinking.

Therefore, in order to have enough surface area to keep up the process of absorption and excrement, the cell will stop growing at the certain point and this process is similar in most if not all organisms.
