Answer:
In addition to vocalization, a mother sea lion locate her pup using a variety of behavioral signals such as moving inside their colony, returning to a familiar location within the colony where she frequented to feed her pup, visual cues and olfactory cues like smelling the approaching pups.
Explanation:
Sea Lions belong to the scientific order Pinnipedia and the family Otariidae. They can walk on all fours on land by rotating their pelvic girdle under their body and also use their front flippers to move in the water. During their breeding and pupping (birthing) time, they gather in groups called rookeries. They can communicate through vocalizations (barks, growls, and grunts) both on land and in water.
After the return of mother sea lions to the rookery from their searching for food (foraging), the mother-pup pairs identify and locate each other through the exchange of vocalizations. In addition to vocalization, the mothers often return to a home spot (familiar location within their colony where a female frequented to feed her pup), move inside the colony and also use visual and olfactory cues like smelling the approaching pups to correctly identify their pup. Also, the return of the mother to a familiar home spot provides the pup with spatial and geographical memory cues.
Answer:
d) The conversion of genetic information from the language of nucleic acids to the language of proteins
Explanation:
1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=<span>149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's
The correct answer would be D, because the ending result for mitosis is 2 diploid cells, meaning the number chromosomes are the same. While in meiosis, the ending result is 4 haploid cells. Because the cell was divided twice, this means that each daughter cell has half of the number of chromosomes.
Cyanobacteria, also known as blue-green algae, are found in vast quantities in fresh and salt water. Cyanobacteria are able to conduct photosynthesis. By utilising energy from the sun, they produce carbohydrates from water and carbon dioxide. As a byproduct, they produce oxygen. So cyanobacteria provided oxygen to the atmosphere that allowed other lifeforms to develop.
