The distance traveled by an object divided by the time it takes to travel that distance is called
a. average velocity.
c. average acceleration.
b. average speed.
d. activity.

Answers

For the first question it would be (B), enhanced physical ability, because this is just a myth
and the second question would be (B) for average speed. d/t=average speed, think of it like 2m/s it's meters per second, distance over time

Exons of a gene are defined as (A) the untranslated regions of the corresponding mRNA
(B) regions in the corresponding mRNA that are involved in initiation of transcription
(C) regions that are not transcribed by RNA polymerase
(D) regions that are excised from the corresponding protein after it is synthesized
(E) regions that remain in the corresponding mRNA after splicing

Answers

E) because the exons remain present within the final mature RNA product of that gene after introns have been removed by RNA splicing.

The science of grouping and naming organisms is called what.

Answers

taxonomy is the science of naming organisms
Taxonomy is the science of grouping and naming organisms.

Cells in organisms need food, air, and waste removal. how are these needs met? organs and tissues perform these functions for the cells. each cell must specialize in all of these functions. cells get their food from the air and sunlight around them. cells share their waste with other cells.

Answers

I believe the correct answer from the choices listed above is the first option. Cells in organisms are able to met the said needs since they have organs and tissues that perform these functions for the cells. 
Hope this answers the question. Have a nice day.

Answer:

The correct answer would be organs and tissues perform these functions for the cells.

In multi-cellular organisms, similar cells work in integrity to form tissues which in turn form organs.

The organs together form an organ system.

The organ system performs specific functions with the help of specific organs and tissues.

In addition, the organs and tissues help all the associated to get food, air, and remove waste.

For example, blood vessels supply blood to each and every organ and tissue which then ensure that each cell gets food and oxygen.

Anthony is studying how quickly children tire based on the amount of sugar they ingest. He splits a group of 20 children into 2 groups. One group is given sugar and the other is not. Anthony asks the children to start playing at a playground at the same time, and to stop when they tire, measuring the time each child stops playing. He finds that the children who did not ingest sugar played 2 minutes longer than those who did ingest sugar. Anthony rerandomizes the data, calculates the difference between the means, and creates the dot plot shown below. Based on the data, can Anthony conclude the difference is significant?A: Yes Anthony can conclude the difference is significant because a 2-minute difference is not likely to happen by chance B: No, Anthony cannot conclude the difference is significant because a 2-minute difference is likely to happen by chance. C: Yes, Anthony can conclude the difference is significant because 0.25 is the difference in means that occurs most often. D: No, Anthony cannot conclude the difference is significant because 0.25 is the difference in means that occurs most often.
