1 answer:

4 0

I. Cerebrum - has many functions including speech, personality, memory
ii. Cerebellum - coordinates movement
iii. Hypothalamus - homeostasis (regulates hunger, thirst, sleep-wake cycle, temperature, blood pressure, heart rate, stomach/intestine activates), produce hormones (oxytocin, antidiuretic hormone), autonomic nervous system control center
iv. Medulla oblongata- controls vital reflexes: heart rate, respiratory rate, blood pressure. non-vital reflexes: sneezing, coughing, vomiting
v. Spinal cord - carry information from the pns to the brain, carry information from brain to PNS vice versa, spinal reflexes

Andy is studying the effect of sunlight on the growth of plants. He selected three identical plants with a height of 15 cm for t

Serggg [28]

Answer:

Analyze the data

Explanation:

A hypothesis is first coined before the experiment is conducted. Usually is a null hypothesis of no change. In this case it would most probably be ‘The is no relationship between the amount of sunlight that a plant receives and it's growth’

After the experiment, the observed data is collected and analyzed using statistical methods. The result of the data will determine where the null hypothesis will be adopted or rejected.

Research is done way before the experiment is conducted to provide headway.

Mars2501 [29]

Answer:

This question is incomplete

Explanation:

This question is incomplete because of the absence of options but the complete question is in the attached picture below.

The human genome is the basic genetic code, or blueprint, for the transfer of traits from parents to offspring through -hereditary transmission- . Studying this code -has revealed- ways to partially correct genetic defects after birth. It is already clear that behavior is rarely controlled by -a single gene- . Rather, almost all behavior involves -multiple genes- , and often specific -environmental- factors influence how genes are expressed.

It would be noted that some of the options were not chosen at all, this is because this question focuses on genes and it's expression. "Nurture and education" and "psychological" are not factors that actually affect gene expression. Also, studying genetic codes has already revealed partial ways to correct genetic defects and hence it would be wrong to choose "may in time reveal". For instance, there are procedures used to identify genetic defects in the spermatozoa of a male which can be screened out and the "good" sperm used to fertilize an egg in-vitro.
