<h2>Answer:</h2>

The right option is (D) Light has no effect on growth

<h2>Explanation:</h2>

The graph shows the relation between growth and time period of the seed in the presence of sunlight. As we can see that there is no significant change on the growth in the presence of sunlight. So we can say that light has no effect on the growth of this seed

How does phagocytosis occur in the lungs?

diamong [38]

Answer:

Phagocytic defense in the normal lung is shared principally by two kinds of cells - alveolar macrophages that reside on the air surface and roam the alveoli and PMNs that circulate in the intravascular space or are stored transiently in areas adjacent to the capillary-alveolar interface (marginated in capillaries)

juin [17]

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.

Explain why the greenhouse effect is necessary but how an enhanced greenhouse effect can harm the planet.

madam [21]

Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming

Earl Sutherland won the Nobel prize for discovering how epinephrine stimulates the breakdown of glycogen, a molecule that belong

Levart [38]

Answer:

There was no receptor for epinephrine to associate with and invigorate the sign transduction course that prompts the actuation of the compound

By and large, Earl Sutherland helped in translating and discovering the breakdown of the glycogen into glucose-1-phosphate in nearness of glycogen phosphorylase and this sign course pathway is activated by the epinephrine. The epinephrine doesn't have the correct receptor to discover and start the sign transduction process and thus glucose-1-phoshate isn't shaped. It requires CAMP which is again a second delivery person for starting the entire of the transduction procedure.
