A BISC 220 student went swimming at the Uytengsu Aquatics Center. Having missed an important lecture on the respiratory system, he thought it would be a good idea to hyperventilate for a minute before diving into the pool and swimming vigorously underwater. Shortly after he began swimming, he lost consciousness and would have drowned if not for the quick action of the lifeguard. Which one of the following best describes what happened?
A. Hyperventilation increased the Poz in his blood, which inhibited the brainstem respiratory center.
B. Hyperventilation decreased blood Pco2, which reduced respiratory drive at the same time that exercise increased the demand for O2
C. Skeletal muscle activity caused an increase in blood pH, which suppressed brain function and made him faint.
D. Hyperventilation increased the saturation of hemoglobin with O2, but vigorous exercise caused the bound O2 to be replaced by CO2
Answers
Answer:
B. Hyperventilation decreased blood Pco2, which reduced respiratory drive at the same time that exercise increased the demand for O2.
Explanation:
Hyperventilation is a breathing at an abnormal rate. There is an increased rate of loss of carbon dioxide which causes an increased demand for the oxygen. The respiration process is affected due to hyperventilation.

plz can i get brainliest:)
Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.
What is corrosion?
The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.
The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.
Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.
Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.
Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.

Briefly explain the nature of scientific inquiry. Include discussion of the role that evidence and falsifiability play in the process. Is this a strength or a weakness of the scientific mode of
thinking?
Answers
Answer:
Science is a process that involves proof and error. Scientific hypotheses are used to find evidence supporting scientific statements, but new evidence can be used to reject previously accepted ones in order to get closer to the truth.
Explanation:
Scientific inquiries refer to the processes by which scientists study phenomena of the natural world and propose alternative explanations (hypotheses) useful for understanding such mechanisms. When hypotheses are supported by many evidence and studies from different sources, scientific theories associated with these hypotheses become accepted by the scientific community. In science, a scientific statement may become falsifiable when it is contradicted by new lines of evidence and/or new observations.

In the late 1980s and early 1990s, the percentage of Icelandic children whose bacterial infections were caused by bacteria resistant to penicillin rose at an alarming rate. After public health officials initiated a campaign to reduce the use of penicillin, resistance dropped off. This observation is consistent with the hypothesis that ________.
Answers
Answer:
The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".
Explanation:
The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.
In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.

What do you mean by cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body. There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation.
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

In plant and animal adaptations, form follows function. True or false?
Answers
Answer:
FALSE
Explanation:
In plant and animal adaptations, form follows function. it is true because all forms of organisms give adaptive advantages.
AdaptationLiving beings tend to have adaptations according to the environment in which they live. Plants in hot and dry climates generally have their leaves reduced, or even modified into thorns, as a way of reducing the contact surface and thus avoiding transpiration.
Whit this information, we can conclude that in plant and animal adaptations, form follows function. it is true because all forms of organisms give adaptive advantages.

the blood speed in a normal segment of a horizontal artery is 0.15 m/s. An abnormal segment of the artery is narrowed by an arteriosclerotic plaque down to one fifth its normal cross sectional area. What is the difference in blood preassures between the normal and constricted segments of the artery. The density of the blood is 1060
Answers
Answer:
286.2 pa
Explanation:
Blood speed in a normal segment of a horizontal artery ( v2 ) = 0.15 m/s
Density of blood = 1060 kg/m^3
Normal sectional area = A2
constricted sectional area ( A1 )= 1/5 A2
Determine the difference in blood pressures between the normal and constricted segments
we will apply Equation of continuity Av = constant
Δ p = 12 PV^2
= 12 * 1060 * ( 0.15 )^2
= 12720 * 0.0225 = 286.2 pa
