<u>Antibiotics:</u>
"Medicines used against bacteria are called antibiotics."
<u>Example:</u>
Rifampin, isoniazid.
Mycobacterium Tuberculosis is a bacteria.
However, some of its strains are resistant to antibiotics and thus is classified as multidrug resistant (MDR resistant)

<h3>~AH1807</h3>
Answer:
Explanation:
the two populations will become different species over time due to accumulated mutations occuring in both populations
Calcium levels in the body are maintained by hormones. If the blood calcium level rises above a set point, calcitonin is secreted by the thyroid gland and sets into motion responses to lower the blood calcium back to the set point. If the blood calcium level falls below a set point, the parathyroid gland secretes parathyroid hormone that sets into motion responses to raise the blood calcium. These homeostatic responses are examples of:
a. positive feedback
b. effectors
c. sensors
d. negative feedback
Answer:
d. negative feedback
Explanation:
Negative feedback responses are the ones that counteract the change. Any alterations in the internal body conditions such as blood calcium levels are sensed by receptors. The information is sent to the brain which in turn commands the effectors such as endocrine glands to secrete the required hormones to restore the normal conditions. Here, changes in the calcium levels are counteracted by the secretion of calcitonin and parathyroid hormones and the calcium is maintained within a narrow range. This represents negative feedback.
The only mutations that matter to large-scale evolution are those that can be passed on to offspring. These occur in reproductive cells like eggs and sperm and are called germ line mutations. Effects of germ line mutations. A single germ line mutation can have a range of effects: No change occurs in phenotype.
