The correct answer is: C) secreting releasing and inhibiting factors into a tiny portal system.
Hypothalamus is part of the brain that consists of many nuclei and has the function to connect the nervous system to the endocrine system via the pituitary gland. Hypothalamus is linked with the anterior pituitary via hypothalamic–adenohypophyseal axis. Releasing hormones or factors produced in hypothalamic nuclei are first released from the prolongation of the hypothalamus and then into a tiny portal system called hypophyseal portal system. This system of blood vessels transports hormones to the anterior pituitary where they act on the secretion of adenohypophyseal hormones.
Answer:
Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.
Explanation:
Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.
D can be eliminated because the temperatures where changed in 3 ways, not two.
A is true, but doesn't apply to the actual experiment "design"
B we don't know for sure, it just looks like a cup/glass.
Best answer for you: C
C is true- it was tested with a single independent variable (one that does not change) on multiple trials (the different temperatures)
d.a population at carrying capacity
i hope this helps u i m not sure about the answer though
