Answer:
Carbon dioxide controls the amount of water vapor in the atmosphere and thus the size of the greenhouse effect. ... This means that Earth's temperature will increase at least another 0.6 degrees Celsius (1 degree Fahrenheit) because of carbon dioxide already in the atmosphere.
Answer:
There are several factors that affects the population of a species in an area such as environmental conditions, number of predators and availability of food.
When first species of arrives in the city, city has adequate food and no predators, then the population of birds has increased for few years before arrival of the second flock of birds.n But after the arrival of second flock of birds after many years (might be 10 to 20 years) the population of first species of birds will decrease because now competition for food has increased and both the species will compete for same food present in the city. Extra birds arrival in the city will increase the competition among both species birds for food and the fittest bird will be able to survive.
Hence, the population size of birds (first flock) will decrease in the 10 to 20 years after the extra birds arrive.
Its the fourth one hope i helped

If a given hormone stimulates another endocrine gland to secrete the original hormone is called Neuroendocrine.
Certain cells are said to as neuroendocrine because they release hormones into the blood in response to nervous system activation. Neuroendocrine tumors are slow-growing when compared to more prevalent malignant tumors, but they can create amino acids that have serious side effects.
To minimize the severity of symptoms or to avoid potential liver damage, aggressive therapy is advised. Nerve and hormone-producing cells share characteristics with neuroendocrine cells. Neuroendocrine tumors can develop anywhere in the body and are uncommon. Most neuroendocrine tumors develop in the pancreas, rectum, appendix, small intestine, and lungs.
