Answer:

Phosphate group

Explanation:

Each nucleotide consists of a heterocyclic base linked via a five-carbon sugar (deoxyribose or ribose) to a phosphate group. DNA and RNA each contain four different bases. The purines adenine (A) and guanine (G) and the pyrimidine cytosine (C) are present in both DNA and RNA. So both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine). One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach.

<h2>Adenosine triphosphate</h2>

Explanation:

ATP, or adenosine triphosphate, is synthetic vitality the cell can utilize.
The particle gives vitality to your cells to perform work, for example, moving your muscles as you stroll down the street.When ATP is separated into ADP (adenosine diphosphate) and inorganic phosphate, vitality is discharged.
ATP is converted into ADP which can be recycled back into ATP Is Converted into A waste product that The cell excretes ATP Is broken down into its individual parts and would need to be re-made Through metabolism to be used again.
At the point when one phosphate bunch is expelled by breaking a phosphoanhydride bond in a procedure called hydrolysis, vitality is discharged, and ATP is changed over to adenosine diphosphate (ADP).
ATP works as the vitality cash for cells. It permits the cell to store vitality quickly and transport it inside the cell to help endergonic concoction reactions.
As ATP is utilized for vitality, a phosphate gathering or two are withdrawn, and either ADP or AMP is created.

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.

How does the type of rock in Earth's crust affect the distribution of groundwater

Ilia_Sergeevich [38]

Answer:

Obviously, such rocks transmit only small quantities of water and are poor aquifers. By comparison, rocks such as fractured sandstones and cavernous limestone have large connected openings that permit water to move more freely; such rocks transmit larger quantities of water and are good aquifers.
