It gets blurry and further away because it is not changing
The incorrect among the choices is "<span>direct signaling involves the activation of g proteins"
This is incorrect because direct signaling does not involve the activation of g proteins rather it involves the activation of ion channels resulting to either an excitation reaction (depolarization of the membrane) or an inhibition reaction (hyperpolarization of the membrane); and this will ultimately affect the action of the organ the nerve is innervating.</span>
Answer: Can not get carbohydrates and will die from the lack of energy!
Explanation: The plant will be unable to produce carbohydrates and will die quickly from the lack of energy and because green light is not absorbed by the photosynthetic pigments.
The answer is right below.
The bulk of this species’ diet consists of fish in the teleost infraclass, including dragonfish, rattails, anglerfish, and more. They are also known to feed on crustaceans and cephalopods like squid.
These sharks will prey on fish found both on the sea floor and in the water column. Because they are so slow moving, scientists believe these sharks are ambush predators. Their pinkish-red skin actually blends in when in the deep sea.
Answer:
True
Explanation:
Some deviations from normal homeostasis activate the positive feedback loops to control the conditions which are otherwise regulated by negative feedback mechanisms.
For example, the blood levels of respiratory gases and H+ ions are regulated by a negative feedback system via chemoreceptors. The increased partial pressure of carbon dioxide gas and lowered pH or lowered partial pressure of oxygen in the blood are sense by central and peripheral chemoreceptors which in turn activate the neurons of the dorsal respiratory group (DRG).
The activated DRG triggers an increased in the rate and depth of the breathing to facilitate the inhalation of more oxygen and exhalation of CO2 to restore the normal levels.
However, hypocapnia inactivates the chemoreceptors and does not allow negative feedback to restore the normal CO2 levels in the blood.
Under such conditions, the positive feedback loop stimulates the DRG neurons more strongly in response to the increased partial pressure of CO2 above the normal levels than when the partial pressure of oxygen falls below the normal level. These dangerously lowered oxygen levels may also cause fainting.
