When you move your fingers to type a text message, you are using motor neurons of the Central Nervous System, which is in charge of most voluntary movements in the body.
Answer:
The correct answer is option B) "Species trees should be constructed using multiple loci (both nuclear and mtDNA)".
Explanation:
Gene genealogy is defined as the inference of relationships between individuals by using DNA testing in combination with the analysis of traditional genealogical and historical records. Gene genealogies could not be established using an unique genetic loci, since not always the same loci vary among individuals. Therefore, species trees should be constructed using multiple loci (both nuclear and mtDNA), to avoid erroneous inferences obtained by analyzing loci that do not vary among individuals.
Answer:
The correct answer is Adrenocorticotropic hormone
Explanation:
Adrenocorticotropic hormone is a hormone from the anterior pituitary whose function is to stimulate the adrenal cortex (fasciculate and reticular areas); In other words, its biological function is to stimulate the secretion of cortisol. The ACTH test is used as an indicator of pituitary function and is useful in the differential diagnosis of: Addison's disease,Congenital adrenal hyperplasia,Cushing's syndrome.ACTH secretion is pulsatile and shows a diurnal variation in plasma concentrations, being maximum at approximately 8:00 am and minimum at midnight. ACTH secretion increases with stress.
Answer:
This question is incomplete as it does not contain the representation of the experiment, however, based on general understanding, the answer is:
Carbon dioxide (CO2)
Explanation:
Yeasts, as stated in this question, are living unicellular organisms that belong to the KINGDOM FUNGI. They employ both the aerobic (with oxygen) and anaerobic respiration (without oxygen) in breaking down sugars. However, both methods of cellular respiration gives off CARBON DIOXIDE (CO2) as a byproduct.
Therefore, when a yeast is placed in a balloon in accordance to this experiment and is allowed to perform respiration either aerobically or anaerobically, it gives off CO2 gas, which causes the balloon to expand.
