Answer:
Hypotahlamus
Explanation:
Hypothalamus has a very critical role in regulating and maintaining the homeostasis of the body and all its cell. It controls the autonomic nervous system, endocrine system and sleep wake cycle of the body. It responds to variety of signals ranging from the emotions, body temperature, and sensations of hunger and thirst to blood pressure and stress through secretion of hormones itself or by stimulating pituitary gland or pineal gland.
Given: The systolic arterial blood pressure observed for 20 dogs is normally distributed with a mean of 152 mm of mercury (Hg) and a standard deviation of 18 mm of Hg.
To find: P(100 < 152)
Method: Calculation of Z-Score followed by the probability or area of the bell curve at X = 100.
Solution:
Mean u = 152, std s = 18
Z score =
The value of P(100<152) is calculated by looking at the value of Z in the Z score for the standard normal distribution given in the image.
P(Z=-2.89) = 0.0019
The P(Z = -2.89) corresponds to the area in the left tail of the bell curve.
Thus the probability of 100 mm Hg blood pressure is 0.0019.
The eggs will have 5 chromosomes and the sperm would have 5 chromosomes because when they combine, they equal to a total of 10 chromosomes.
Answer: unlike modern-day evolutionary geneticists, Darwin did not have the knowledge of modern-day genetics or the ability to sequence the genome. So, Darwin couldn’t have determined that the trait of flightless wings was likely caused by a genetic mutation.
Explanation:
The statement that correctly pairs biotic factors with an effect on the biosphere is that biotic factors would decrease the oxygen in the soil.
<h3>What are biotic factors?</h3>
Biotic factors of an ecosystem refers to the living components of that ecosystem. Biotic factors include the following:
Biotic factors make use of oxygen in the atmosphere to perform the process of respiration, hence, their presence will cause a decrease in the oxygen content.
Therefore, the statement that correctly pairs biotic factors with an effect on the biosphere is that biotic factors would decrease the oxygen in the soil.
