Answer:
False
Explanation:
The function of ACTH (adrenocorticotropic hormone) is to regulate levels of the steroid hormone <em>cortisol</em>, which released from the adrenal gland. It is a <em>tropic</em><em> </em><em>hormone</em><em>,</em><em> </em>so it causes no direct effects
Answer:
Darwin's research on Galapagos Island put forward his theory of natural selection.
Explanation:
1. Charles Darwin studied the similarities of the finches between the various islands of Galapagos. His study noted that the finches were similar from island to island making him to wonder about the origin of this species as these perfectly adapted to their environment. His compilation of observation about the finches, the fastest evolving vertebrates, described its behavior and appearances which changed according to the changing environment., thus making them to adapt quickly. These were further converted for his book 'The Origin of Species' that changed the concept of evolution.
2. Grants research on Galapagos Islands were conducted by Peter Raymond Grant and Barbara Rosemary Grant, both evolutionary biologists. Their work focussed on the Darwin's finches through processing of collecting blood samples and tagging them. They were able to indicate that changes within the species is evident within a single lifetime. Their study indicted that changes in populations takes place quickly and need not wait for long time as indicated in Darwin's theory.
3. The Galapagos Island is a ground to more species that have risen due to adaptation. Due to its remote location, it was possible for the scientists to conduct study about natural selection on biodiversity. THere are 18 species that have evolved from Darwin's finches. The diversification observed in the finches were the shape and size of beaks.
The Darwin's finches developed over time with strong crushing and probing beaks adapted to catch insects or crack nuts. Even some have sharp long beaks to drink blood.
Another species observed is the marine Iguana with adapted short blunt stout, and long tail to swim deep into sea.
The flightless cormorant found in this island, were adapted to survive as there was no necessity to fly. Instead their dense bodies, small feet, and powerful legs makes them to be good divers to hunt fish, eels, and small octopus.
Answer:
The correct option will be option C.
Explanation:
2,4-Dinitrophenol or DNP is a protonophore molecule which can leak the protons and leads to affect the production of ATP in the mitochondria.
DNP is the best agent known for uncoupling the oxidative phosphorylation as it uncouples the phosphorylation of adenosine diphosphate (ADP) from ATP synthase. It leads to the low production of the ATP during oxidative phosphorylation and most of the energy is converted to heat. It does not effect the electron transport chain, it continues.
Thus, option C is the correct answer.
Answer:
4) d
Explanation:
In the given figure, <u>A is a wavelength</u> which is the distance between two crests of a wave. <u>B is a crest</u> which is the highest point located on a wave at maximum distance upward from the middle of the wave. C is a trough which is an opposite of crest meaning that it is the lowest point on a wave from the middle.
Lastly, <u>equilibrium</u> is a point located in the middle of wave. In other words, it is the average of crests and troughs located on a wavelength.
Biological measurements are the parameters associated with biological systems. An incorrect diagnosis and medical interventions are some measurements due to poor classification.
<h3>What are risk factors?</h3>
Risk factors are the biological, psychological, or social influences that affect the result or the outcome that can be positive or negative. The biological measurement risk factors might include the organism's system.
The poor classification of the biological risk factor can lead to an incorrect diagnosis of the condition followed by medical treatment and procedures that might have side effects.
Therefore, the medical diagnosis and intervention can be some risk factors.
