the respiration rate will increase as temperature increases. An increase in temperature will minimize the amount of dissolved oxygen in the water and increase the metabolic rate of the goldfish, thus causing the goldfish's respiration rate to increase (“Hot waters make it hard for fish to breathe”).
Answer: Birds pick up oil on their beaks, by rubbing against the uropygial or preen gland near the tail, and then rub it over their feathers. This makes the water unable to break through the oil.

<span>Metamorphic rocks form by existing rocks join together under high heat and pressure. Examples of metamorphic rocks are marble, schist, slate, and quartzite. Metamorphic rocks formed when the minerals are chemically changed due to heat and pressure. They are often seen near magma but they do not melt like igneous rock.</span>
Answer:
Option B
Explanation:
ALL options are as follows -
a. teosinte and maize can produce fertile hybrids.
b. teosinte and maize have similar chromosomes.
c. Both Teosinte and maize have naked, soft kernel.
d. Teosinte and maize can produce fertile hybrids
Solution
Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.
During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.
He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.
Option B is correct
All are aspects of antibiotics resistance in bacteria.
• overuse of antibiotics in humans
• bacteria can reproduce so quickly
• any use of antibiotics will select for resistant bacteria
• overuse of antibiotics in livestock
