Answer:
Option A is the correct answer. To conduct a controlled experiment would be the best choice for Maria to test her prediction.
Explanation:
A controlled experiment can be described as an test in which one of the test models is kept constant for a variable, while in other experimental models, a change is made for testing the variable.
It would be best for Maria to conduct a controlled experiment. In the control model, Maria should keep light as constant whereas in other experimental models she should increase and decrease the quality of light to test her prediction. She should then compare her experimental results with the control model to deduce the results.
Other biological molecules that contain the element of N would be nucleic acids such as DNA and or RNA. There are found in the nucleotides that constitute or make up these nucleic acids.
Answer:
barbiturate/sedatives
Explanation:
Lateralization is a process of studying the split functions of the brain hemispheres. The most common test used for testing lateralization is obtained from sodium amytal studies. In this study a barbiturate or a sedative is injected into the carotid artery either left or the right artery. So, till the time the barbiturate hampers the functioning of any hemisphere, the functions associated with that hemisphere also gets hampered or are sustained for a while. This technique is of invasive nature
Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.
The risk of schizophrenia among biological relatives is greatest for identical twins. This is a true statement.
<h3>What is schizophrenia?</h3>
Schizophrenia is a neurological disorder that causes an affected individual to lose touch of reality.
Schizophrenia can be caused by the following:
- Genetics: Gene defects caused by mutation such as deletions or duplications of genetic material increases risk of schizophrenia.
- Environment: Urbanicity, migration, cannabis, childhood traumas, infectious agents, obstetrical complications and psychosocial factors
- Brain chemistry and circuit
- Brain abnormalities: Impaired communication between brain regions leads to the associated symptoms and cognitive changes.
According to research, the risk of schizophrenia among biological relatives is greatest for identical twins because they are genetically identical.
