To further scientific knowledge, what four steps should scientists take after they analyze their results?
stepan [7]

Answer:

A: Draw conclusions about their data.

Explanation:

A important step in the scientific methodology, once the results are analyzed is to draw reasonable conclusions about the whole experiment. For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic. This is an important step in the scientific methods which concludes our work and makes it more impact for the upcoming scientists interested to work on problems of similar nature.

Hope it helps!

If a researcher is interested in measuring both the structure and function of the brain, which technique might one recommend
Anettt [7]
The best method for studying both the structure and the function of the brain would be the functional magnetic resonance imaging (fMRI).
This technique measures the blood flow to different brain regions in order to determine which areas are active in certain brain processes. An increase in the blood flow increases the amount the oxygen the area is receiving that is needed for the functioning of the nerve cells.

In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan—a spotted, red and white
8_murik_8 [283]

Answer:

25% red

50% roan

25% white

Explanation:

When RR (red) is crossed with WW (white), it results in roan color.

       RR (red)   x    WW (white)

              RW (roan)

Two roan individuals are then mated.

          RW    x    RW

       RR    RW    RW    WW

Offspring

1/4 RR - Red

1/2 RW - Roan

1/4 WW - White

<u>Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.</u>

Dale’s _____ carry instructions from his central nervous system to his muscles.
Sliva [168]

Dale’s motor neurons carry instructions from his central nervous system to his muscles.

Motor neurons are special brain nerve cells that transmit impulses from the brain or spinal cord to a muscle or gland. The motor neurons functions with a network of other neurons, situated within the spinal cord and the brain. The two main subtypes of the motor neurons are; the upper motor neurons (which comes from the brain and connects with the lower motor neurons), and the lower motor neurons (which localize in the brainstem and the spinal cord).
