Biologist is a scientist and should follow the scientific method - to investigate, report and analyse what he finds.  So the correct ans is A.

The most sensible answer is to:
A) Report his findings.

As a scientist it is his job to conduct experiments based on hypothesis or theories and from this experiments, give a detailed description, explanation, and conclusion about the experiment. This is the reason scientists and doctors write articles about their research, to make the public aware of such discoveries so that future researchers don't have to spend time valuable time and further studies can be based on such experimental report.

D) Would also be correct 'If' the scientist didn't find the expected answer to his hypothesis. This would cause the scientist to perform further experiments to find a reasonable justification and give a conclusion about it. If by the end of his studies, the research concludes that his hypothesis is incorrect, he must change his hypothesis based on scientific truth.

Both B) and C) are the least likely answers because:

B) is an immature action to take, showing the scientists lack of control. Throwing away experiment notes is not the wisest move to take as these notes not only provide valuable information about the experiment but can actually prove to be important data, that if analysed well it could show the scientist his mistake/error, a new unobseved pattern or give him a new hypothesis or idea. Thus proving to be very valuable.

C) As a scientist, it is his right to be a very genuine about his work as he is given a credibility by science. Lie is one of the greatest sin to a scientist as it causes his credibility to collapse and even lose his title as a scientist.

Explain two ways in which the sale of local souvenirs promotes the culture of the destination
Salsk061 [2.6K]

The correct answer to this open question is the following.

Although you did not specify what destination you are referring to, and there are no options attached, trying to help we can say the following.

The two ways in which the sale of local souvenirs promotes the culture of any destination are the following.

Souvenirs and merchandise are an excellent way to promote a country, a city, or a tourist place. Visitors can buy souvenirs that are homemade by local people, helping to maintain an economic activity to generate income and pay taxes that benefit the community.

When tourists wear clothes, shirts, sweatshirts, hats, with the name of the place, they are promoting that tourist destination. When they buy commemorative plates, cups, mugs, glasses, posters, and exhibit them in their homes or offices as a decorative item, they are also promoting the touristic destination.

The girl in the picture is at the highest point in swinging and starts to come down. Which statement best describes the changes
SpyIntel [72]

When she descends the potential energy will decrease at the same rate that the kinetic energy increases.

<h3></h3><h3>How to describe changes in energy?</h3>

We know that we can write the total energy of a moving object as:

E = U + K

Where U is the potential energy and K is the kinetic energy.

In the given case, U will only depend on the height of the girl and it will be maximized when the height is maximum.

K = (1/2)*m*v^2

where m is the mass and v is the velocity.

When the girl is at the highest point, the velocity becomes equal to zero. This happens because at that point she stops going up and starts going down, so the velocity must be zero at that moment.

Then we have K = 0.

E = U.

As she starts going down, the velocity starts increasing and the height decreases, thus, the kinetic energy increases and the potential energy decreases. This relates to the conservation of energy. E will always be the same value, but K and U will depend on the position of the girl.

This means that if the potential energy decreases a quantity e', then the kinetic energy must be increased by that same amount.

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti
nadya68 [22]

No product results in -1, hence δlmn is NOT a right triangle showing that  lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn  is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1

For the slope of ln:

m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\

For the slope of mn:

m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\

  • If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

  • To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2

Since no product results in -1, hence δlmn is NOT a right triangle showing that  Lydia's assertion is incorrect
