Answer: The correct answer is-

Coccus bacteria.

Bacteria are unicellular, prokaryotic organisms that is they are made up of single cell and lack nucleus and membrane bound organelles.

Based on their structures, they exist in primarily three shapes that are-

1) Coccus ( cocci for plural)-The cocci are round/spherical or oval shaped bacteria.

Example- Streptococcus pyogenes, Staphylococcus aureus

2) Bacillus ( bacilli for plural)- They cylindrical/ rod shaped or capsule like bacteria.

Example- E.coli.

3) Spirullum ( spirulli for plural) - They are spiral shaped bacteria.

Example- Spirillum volutans.

What conditions cause cells to break down fat molecules?

chubhunter [2.5K]

Starvation. When the body enters starvation mode or fasting for long periods of time, the body will start to tap on the stored fatty acids to produce ketone bodies. These ketone bodies will build up in the bloodstream, and will also be available if the brain has used up the stored glucose.

_____ can be prescribed to therapeutically lower cholesterol levels.

maxonik [38]

Answer:

Niacin can be prescribed to therapeutically lower cholesterol levels.

Explanation:

Niacin, known as vitamin B3, is used to reduce the risk of heart attack or stroke in people with high cholesterol. Niacin has gained popularity in the last 50 years and is mainly used to raise the level of HDL (high density lipoprotein) cholesterol, also known as good cholesterol and lowering bad cholesterol levels.

However, niacin can cause health damage, so it should always be used with medical supervision.

Incomplete question. The remaining part of the question read;

Words in the left column:

Yes
No
Observational
Manipulative

1. A physiologist incubates eggs in the lab at a range of temperatures to see what temperatures produce males and what temperatures produce females.

2. A biologist predicts that shade might influence ground temperature, and therefore turtle sex ratios. He records the sex ratio of turtle hatchlings in shaded and unshaded regions

3. An ecologist predicts turtles grow larger when no predators are around. She places turtles in an experimental pond system where half the ponds have predators and half the ponds have had the predators removed.

4. A climatologist predicts that concentration of CO2 in a city will be negatively correlated with the amount of wind in that city. He collects data and looks at the amount of CO2 in a city as a function of the wind speed in the city.

5. A sociologist conducts a survey in Hawaii to describe people's attitudes about global climate change.

6. A scientist determines the average wind speed, and variation in the amount of wind, in a number of locations to see which locations would be most suitable for wind turbines

Answer/Explanation:

1. Hypothesis-driven? Yes!

Observational or Manipulative? Observational.

We can make this conclusion here that the physiologists' research is hypothesis-driven since we are told he wanted to "see what temperatures produce males and what temperatures produce females." In other words, he wanted to know whether the temperature used in incubators can influence the sex of an egg by means of observation.

2. Hypothesis-driven? Yes!

Observational or Manipulative? Observation.

3. Hypothesis-driven? Yes!

Observational or Manipulative? Manipulative.

We can make the conclusion that is the ecologist used the manipulative method in her research since she decided to place the turtles in two different types of ponds; one where half the ponds have predators while in the other the pond the predators have been removed. In other words, she manipulated the independent variables.

4. Hypothesis-driven? Yes!

Observational or Manipulative? Observational.

Note, the use of the word, "predicts" in most instances underscores the tone of hypothesis-driven research, hence we can say Yes! And remember, we are told the researcher "collects data", meaning he is merely observing differences that occur naturally.

5. Hypothesis-driven? No!

Observational or Manipulative? Observational.

6. Hypothesis-driven? No!

Observational or Manipulative? Observational.
