Darwin's "Origin of Species" and Lamark's "Theory of Inherited Characteristics"
The correct answer is Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.
At the time of hunger, the blood glucose level decreases, and glucagon at that time, that is, the hormone discharged by the islets of Langerhans increases the level of sugars in the body. The stored glucose in the liver gets discharged due to the presence of glucagon, which eventually elevates the level of glucose in the blood.
In the given case, when Kai ate the cookies, the level of glucose in the blood got increased and even elevated from the normal level in the blood. At that time, the insulin hormone is discharged from the islets of Langerhans, which helps the cells of the body to absorb the molecules of glucose and thus lowers the concentration of glucose in the blood. Therefore, both the hormones help in monitoring the levels of glucose in the body.
Answer: natrual selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce
Answer:
The correct answer is option (B) "In pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses".
Explanation:
One hypothesis suggest that the tiger beetles stop for a moment when they attack because it can't keep its pace and they have to rest, while the other hypothesis suggest that the tiger beetles could not process the rapidly changing visual information when running. The experiments results would support only the second hypothesis if they show that in pursuing a swerving insect, a beetle alters its course while running and its pauses become more frequent as the chase progresses. If a beetle altering its course have to stop more often than a beetle running straight, it would make sense that it has to stop because is unable to process the changing visual information rapidly enough.
There are nine separate layers of cartilages that protect and frame larynx. The nine layers of cartilages include laryngeal cartilage, cricoid cartilage, two arytenoid cartilages, two cuneiform cartilages, two corniculate cartilages and epiglottis. It is more pronounced in male than in female. all these structures function together to facilitate various process such as respiration vocalization, air protection and swallowing of substances from the mouth into esophagus.
