Answer:
Their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.
Explanation:
Otters are extremely important organisms, also known as "<em>keystone</em>" species. They keep aquatic ecosystems healthy because they control other populations such as sea urchin populations that consume kelp, sometimes in excess.
For this reason, otters prefer inhabiting near the kelp, which generally grows in clear waters near shores. They also prey on crabs, marine snails, squid, etc. as they possess the ability to dive as deep as 250 feet.
Therefore, their survival is correlated to water clarity because kelp, the main food of otters' prey (sea urchins), needs clear water to thrive.
Answer:
D
Explanation:
We can’t use nitrogen from the air and that’s why we have to use bacteria to into something that we can use
Energy is the ability to do work which is stored in the body inform of ATP (adenosine triphosphate). ATP is comprised of a base Adenine, a ribose sugar (5 carbon sugar) and three phosphate groups. when a bond is broken energy is released and when a bond is formed energy is stored. ATP is used by cells as a source of energy such that ATP can easily release or store energy by breaking the chemical bonds and reforming the bonds between its phosphate group. The correct answer is c, phosphate- phosphate bond
Answer:
Random variation in the population led to a population with a favorable adaptation
Explanation:
Insecticide resistance can be defined as an evolutionary process that causes a decreased susceptibility of an insect population to a particular insecticide. The evolution of the insecticide resistance occurs by the mechanism of natural selection, where most resistant insects survive and thus pass on their acquired heritable resistance to their offspring. Moreover, the evolutionary origins of the resistance trait may be associated with different processes: 1-<em>de novo</em> mutations (i.e., the emergence of beneficial genetic changes in the population), 2-standing variation in the original population which is selected under the selective agent (in this case, the pesticide), 3-migration of resistant specimens originally resistant to the pesticide, and 4-even interspecific transfer (i.e., horizontal transfer between different species).
