Which of the following is not a function of the skeletal system?
A.
provides a framework for the body
B.
provides protection for internal organs
C.
movement of bones
D.
production of new blood cells
Answer:
C
Explanation:
The skeleton relies upon the contraction and relaxation of muscles which are attached to bone in order to move. The muscular system is made up of three types of muscle, one of which is responsible for the movement of bone. To add to the confusion, the relationship between both muscles and bones is often lumped together as the musculoskeletal system, but to be sure, they are unique in their own ways.
In summary, bones can't move on their own, and therefore movement cannot be the skeletal system's function.

Is the ocean a carbon sink or a carbon source
Answer:
Explanation:
The Carbon CycleChanges to The Carbon CycleThe Ocean and CarbonBiological Pump
The ocean plays an important part in the carbon cycle. Overall, the ocean is called a carbon ‘sink’ because it takes up more carbon from the atmosphere than it gives up.Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the carbon dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter
the ocean is a carbon sink

1. Choose the items that are Inferential Statistics. (Check all that apply)
Give the likelihood of data occurring by chance
Include the mean
Summarize the data
Tell you whether to call your mother about your results
Give a measure of statistical significance
Answer:
A, D, and E is correct
Explanation: I took the test and got this one correct.
The items that are inferential statistics among the options would be:
Give the likelihood of data occurring by chanceTell you whether to call your mother about your resultsGive a measure of statistical significanceThis is largely due to the fact that inferential statistics refer to the branch of statistics that draws conclusions from a set of data. It is as opposed to descriptive statistics which focus on summarizing, describing, arranging, and or categorizing data in such a way that trends are shown at a glance.
Statistical parameters such as mean, mode, and median only measures attributes of data relating to the measure of central tendencies. Data summary is purely descriptiveHence, the items selected are those that are conclusive and not descriptive.

A reaction that absorbs energy from the environment a reaction that requires an activation energy a reaction that releases energy into the environment a reaction that does not involve a change in energy
Answer:
Endothermic reaction
Explanation:
An endothermic reaction is a chemical reaction that takes energy from the atmosphere. It requires activation energy. An exothermic reaction is the reverse of an endothermic reaction. Reversible reactions are where the compounds will react to the initial reagents.

frank has type A blood (AA or AO) and margarita has type B (BB or BO) blood. They have a new baby. Vinnie, with type O blood. Is this possible or should frank accuse margarita of cheating?
Answer:
It is technically possible, if and only if, both parents have AO and BO blood.
Explanation:
the only way (most of the time) a child can get O blood is if both genes accepted by the parents are O. That would mean both parents would have to have O recessive genes.
21.As mentioned in the video, the environment can also affect an organism's traits. The example of nourishment was used in the case for Spike, as this could affect his growth and size. This can also occur in humans. UV light was not mentioned in the video. How could UV light potentially affect an organism's trait? Provide one example.
Answer:
UV light can modify the DNA of a human being, provoking mutations that affect the traits. For example, exposure to the sun's UV rays affects the DNA of the skin cells, causing mutations that can lead to cancer.
Explanation:
An environmental factor that can affect humans traits is the exposure to UV light that the sun radiates. The DNA in our skin cells absorbs the UV rays. As a result, the DNA can suffer modifications that result in skin cancer. Also, the absorption of UV rays causes wrinkles since cell components are affected due to the accumulation of UV light.

How could flying squirrel adapt further to allow it to be more successful?
Answer:
The structural adaptations of the flying squirrel has developed a good sense of balance, sail-like fur skin membrane that extends from the wrists to ankles, delicate wrist bones that control this membrane, allowing the squirrel to steer, and a fluffy tail that balances out and stabilizes the flight.
When an instruction for a variation of a trait is not shown in by the organism, but the organism carrys it and can pass it on to the next generations, these organisms are called _______.
a
dominant
b
carriers
c
recessive
d
holders
Answer:
b. carriers
Explanation:
Recessive alleles do not create a phenotype if a dominant allele is present BUT the organism itself is called a carrier because it carries the recessive trait.

Francis grew some plants for a science experiment. The sketch of his experiment after several days is shown. Which tropism is Francis most likely investigating?
The correct answer to this open question is the following.
Unfortunately, you did not provide the sketch or the photo that shows what Francis is doing. So we do not know what you are talking about.
However, trying to help you, we did some deep research and can comment on the following.
If the photo shows a plan under the light of a lamp, moving towards the lamp direction, then tropism is Francis most likely investigating is phototropism.
To better understand the concept, Tropism is the movement of a plant towards the direction of an influence exerted on it. This means that an external factor is introduced in order to make the plant grow through an external influence.
So when we use the term phototropism, this means that the plant responds to the direction of the source of light and grows in that direction. That is what Francis is using in his science experiment.
Answer:
phototropism

How does the process of DNA replication impact mutations in an individual?
a All DNA replication stops when there is a mutation so the mutation wont hurt the individual
b Replication only produces new DNA strands so the old stand with the mutation is destroyed
c Since replication keeps the old strands as templates mutations maybe earned into future stands
d Mutations are often lost since the cell will die doring the replication process if the DNA is mutatie.
Answer: A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
