Answer:
Pneumotaxic centre in the pons region of the brain can moderate functions of the respiratory rhythm centre. Neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. A chemosensltive area is situated adjacent to the rhythm centre to make necessary adjustments in the respiratory process. Receptors associated with aortic arch and carotid artery also can recognise changes in CO
2
and H+ concentration and send necessary signals to the rhythm centre for remedial actions. The role of oxygen in the regulation of respiratory rhythm is quite insignificant.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
Explanation:
Answer:
this means that the oxygen is maintained by the respiratory rhythm.

Sigmoidal plots of activity versus substrate concentration are exhibited by a. holoenzymes. b. Michaelis-Menten enzymes. c. allosteric enzymes. d. monomeric enzymes. e. isozymes.
Answer:
The correct answer is C
Explanation:
Allosteric enzyme is an enzyme that has more than one active site on the surface of the enzyme. Generally, the binding to one of these active sites affects the affinity of the other active sites on the enzyme; this causes the enzyme not to follow the Michaelis-Menten's enzyme kinetics. Thus, when the activity versus substrate is plotted on a graph, a sigmoidal curve shown instead of an hyperbolic curve (like other enzymes).
Which statement explains why athletes experience a burning sensation in
their muscles after vigorous exercise?
A. Their muscles have taken in too much oxygen.
B. The conditions in their muscles have become anaerobic.
C. The temperature in their muscles has become too high.
D. Their muscles have become flooded with glucose.
Answer:
B. The conditions in their muscles have become anaerobic.
Explanation:
In humans, cellular respiration occurs naturally in an aerobic condition (presence of oxygen) but anaerobic respiration can be adopted in specific or extreme cases. One of those cases is after or during a VIGOROUS EXERCISE.
What happens is that, after a vigorous exercise by an athlete, oxygen becomes insufficient in their muscle cells due to high consumption. Hence, their muscle cells switch to anaerobic respiration (lactic acid fermentation), which causes the build up of lactate in the muscle tissues. This lactate build up cause athletes to experience a painful and burning sensation in their muscles.
Hence, it all begins when "conditions in their muscles become anaerobic after an exercise".

undesirable side effects that may occur when taking this pill. (2 pts) 5. American soldiers who liberated the Nazi concentration camps at the end of World War II were so moved by the inmates' emaciation that they offered them candy bars and other rich foods. In spite of the inmates' extreme starvation, these foods had to be taken away from them. Explain why. Be specific as
possible. (2 pts)
Answer:
The digestive system can't digest the food properly.
Explanation:
The inmates' extreme starvation, these foods had to be taken away from them because their digestive system can't digest the food properly. When a person experience long duration of starvation, the body can't digest that rich foods properly and has difficulty to digest it so that's why these foods had to be taken away from them and provide those foods which are easily be digested.
Please help me with question 7 ASAP
Answer:
B is the correct answer.
Explanation:
A is incorrect because diffusion does not depend on living system. It can occur in non-living systems as well. C is incorrect because when all transport proteins are used, the transported molecules are carried by the maximal number of transporters. Thus, the transport rate of substance is maximal.
D is false because translocation is primarily related to phloem.

Most carbohydrates manufactured in leaves and other photosynthetic parts are transported through the phloem to the rest of the plant by the process of translocation. osmosis. transpiration. receptor-mediated transport. turgor pressure.
Answer:
Translocation
Explanation:
Translocation is the movement of sugar that is produced by the source( i.e the part of plants where sugar is produced for other plant parts which could be leaves) to the sinks( i.e the active growing parts of plants where sugar is been deposited for use) where it is used up.
Translocation is done through the phloem tissue to sinks. Sinks could include leaves, fruits, shoots, young developing seeds, tubers and stems.
Translocation is done through the pressure flow model where concentration of sugar that is high at the source creates a low solute potential which helps water movement into the phloem from the adjacent xylem. This movement creates a high pressure potential in the phloem that produce the movement of phloem sap by bulk flow from source to sink.

The layers are formed due to difference of density of solutions.
The main cause of the order of the layers is the difference of weight and density of different liquids in the container. The liquids that has more weight means higher density will sink below the liquids that has less weight means lower density so due to difference in their density corn syrup is located at the bottom due to higher density and rubbing alcohol is present at the top of the container due to lower density.
https://brainly.com/question/24277427
What caused the order of the layers can be attributed to the densities of the liquids.
The density of a substance is an indication of how heavy the substance is in relation to its volume. Mathematically, it is given as mass/volume.Hence, a liquid with a higher density will always be at the bottom of a liquid with a lower density provided that both of them are of the same volume.In order words, immiscible liquids poured together in the same container will separate out according to their densities - starting with the highest density liquid occupying the bottom with the lowest density liquid staying topmost.

The space shuttle Endeavor is launched to altitude of 500,000 m above the surface of the earth. The shuttle travels at an average rate of 700 m/s. How long will it take for Endeavor to reach its orbit?
Answer:
Time taken by space shuttle = 714.28 m/s
Explanation:
Given:
Distance cover by space shuttle = 500,000 meter
Speed of space shuttle = 700 m/s
Find:
Time taken by space shuttle
Computation:
Time taken = Distance / Speed
Time taken by space shuttle = Distance cover by space shuttle / Speed of space shuttle
Time taken by space shuttle = 500,000 / 700
Time taken by space shuttle = 714.28 m/s

1.Explain the energetic constraints that prohibit prokaryotes from getting larger than they are. Be sure to explain the implications of the energy canyon for the evolution of eukaryotes.
Answer:
Space constraints.
Explanation:
Space constraints are the energetic constraints that prevent prokaryotes from getting larger than their limit. Space constraints control the sizes of both the largest and smallest bacteria. Bacteria can't shrink more than they have already because there is not enough space left for DNA and necessary proteins. In the same way, the prokaryotes can't increase in size beyond their limit due to space constraints.
What is the most likely explanation for the results in the graph?

need.
B. The apple orchard releases toxic chemicals into the water of the
bay.
C. The nitrogen from the fertilizer makes it impossible for plants to
grow
D. The fish have migrated away from the bay to find warmer water,
SUBMIT
Answer:
B. The apple orchard releases toxic chemicals into the water of the bay.
Explanation:
Option B is the correct answer. It is the most likely explanation for the results in the graph.
From the graph, we can see that the population of the fishes sharply dropped. Since the fertilizer is applied to the apple orchard and the orchard was planted beside the bay, during the rain it is possible that the water has washed some of the fertilizers into the bay. The chemicals used in making fertilizer are harmful and toxic.
This reveals that the toxic chemicals released from the apple orchard are responsible for the decline in the population of the fish.
