I'm so confused help!!! (Will give brainliest)
A population is composed of bacteria that are very sensitive to light. They live in a lake that is in a cave so they flourish. Slowly, however, a hole begins to erode in the cave's roof. As the days pass, light begins to fliter in and the cave starts to be dimly lit. The bacteria begin to die. While the erosion is taking place, however two individual bacteria in the soil above ground fall into the lake. These bacteria cannot survive in the dimness of the poorly-lit cave, so they die immediately. Days later, the hole has opened up so that light floods the cavern. Nevertheless, the bacteria that were once dying are flourishing, with a population larger than they had before the erosion. Explain how this could have happend. There are 2 successive things that must have happened to cause this. What were they.

c. sound scientific ideas are frequently altered.
d. nature is a constantly changing wonder, difficult to understand.

Answers

Answer:

Explanation:

Scientists must be aware of this that science cannot offer solutions to every issue, hence option A is correct.

What is a scientific hypothesis?

A hypothesis is a potential solution to a problem in science, but it isn't just any solution. A hypothesis needs to be rational and supported by scientific information.

Falsifiable claims must be made in science, this implies that they might be tested, and there must be some conceivable observation that may disprove them.

Therefore, a hypothesis or theory seeks to explain or interpret facts, but a scientific fact is, in its most fundamental definition, an objective and verifiable observation, hence option A is correct.

according to the data in model 1, how many males are 181 cm or above in height

Answers

Answer:

9 male individuals are 181 cm or above in height.

Explanation:

You will find model 1 in the attached file.

In the model, you can see a pie chart, a bar graph, and a line graph.

The pie graph shows an approximate proportion of males and females with different highs. What is wrong about this chart is that it does not show the percentages of males and females by heigh. Anyway, we can not answer the question with the given information. The bar graph expresses a comparison between males´ and females´ average height, hand length, and knuckles values. According to this graph, we can not know how many males were 181 cm or taller.The line graph shows the distribution of height in bales and females. Females are represented by a continous line, while males are represented by a pointed-line. So we need to focus on this line to answer the question. The Y-axes shows the number of individuals, and the X-axes shows the heights intervals in centimeters. According to the question, we need to look for the interval that belongs to 181 cm and above. So, the interval between 181-185 cm height corresponds to 6 male individuals. But after that interval, we also have 3 more male individuals that are between a height of 186-190 cm. So, in total, we have 9 male individuals that are 181 cm or above in height.

Explanation:

Mercury has greater cohesion than adhesion.

What is adhesion?

The attraction between two distinct phases is known as adhesion. Adhesion cannot be explained by a single theory, however it is frequently split into two categories: mechanical interlocking and physical and chemical bonding. Adhesion often results from a mixture of the several mechanisms described below.

When two dissimilar phases only attach to one another mechanically, mechanical interlocking occurs. Typically, for the other material to penetrate, the surface needs to be a little bit rough. adhesion processes

For instance, a low viscosity glue that easily penetrates surface pores and fissures. After the adhesive has dried, this causes mechanical anchoring between the two components.

Therefore, Mercury has greater cohesion than adhesion.
