an average adult cheetah has a metabolic mass of 44,010 grams and a resting metabolic rate of 61.77 joules per second. is this information to add a data point for the cheetah to figure 2. based on the data, would u characterize the cheetah as an ectotherm or endotherm? support ur answer with evidence from the graph.

Answers

you should plot the point slightly above those of the chimpanzee and dog, where the blue star is in the graph to the right. They should conclude that a cheetah is an endotherm because its placement on the graph is in trend with the endotherms, not the ectotherms

Nitrogen fixing bacteria play an important part in getting nitrogen
into the soil so that it can be used by plants.
True
False

Answers

True.
Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle.

The Centers for Disease Control (CDC) collect vast amounts of data. For this activity, we want you to use their Natality Information database to test various hypotheses about birth. For the following five issues, please create a hypothesis and then use the database to collect information about the issue. Once you the data is displayed, record it and indicate whether your hypothesis was supported by data.

The database functions in this manner:

Upon going to this website, you will need to comply with the CDC requirements for using the database. Because this is a school activity, you will be fine. Click I Agree.
The top section (Section 1) of the query engine will allow you to determine how your data sets will be displayed. You will want to Group Results by State for the queries you will perform.
Be sure to select the correct measure for your question/hypothesis. Select only one measure for each query.
Section 2 allows to select individual states or multiple states for comparison. If you have selected states in Section 1, you can run multiple data sets here and see them displayed by state. If you did not, the only way to see individual state data is to run the query one state at a time.
The remaining sections include the conditions you can use for comparison. You will need to find the appropriate section for the condition you are testing for. Once you have found it, go ahead and run your query by clicking Send.
Let me talk you through the process. Seriously, watch this video explanation of what you're doing.

Here's an example. Which state, Utah or New York, has the highest average age for mothers giving birth?

Hypothesis: New York has the highest average age for mothers giving birth.
Data (based on the following settings)
Section 1: Group Results by State; Measure: Average Age of Mother (years)
Section 2: Select Utah and New York

Run the report (click Send) and the data says that New York's average age of mothers is 30.26 and Utah's is 28.59
Supported hypothesis: Yes
Data Questions
Now run the data queries for the following questions and record your hypothesis, data, and whether your hypothesis was supported.

What characteristic of water causes it to display adhesion cohesion high specific heat capillary action

Answers

I think the answer should be the fact that water is a polar molecule.

This means it will attract other molecules which are polar (adhesion), including itself (cohesion).

I'm not sure about the last part of the question (high specific heat capillary action, the wording is a little confusing), but I think the reason why water has a high specific heat is the hydrogen bonds. Hydrogen bonding is the strongest kind of bond you can have in a molecule, so it would be harder to break those bonds, even with high heat.

Answer:

The polarity of water
