Answer:
<h2>
Endosymbiotic theory states that some organelles found in eukaryotic cells arises from prokaryotic cells.</h2>
Explanation:
The Endosymbiont theory proposed that mitochondria and chloroplasts evolved from some bacteria that were ingested by primitive nucleated cells. Chloroplast and mitochondria have characteristics similar to bacteria. They divide by binary fission as well as contain single circular DNA and 70s ribosomes found in prokaryotes. It was believed that mitochondria had evolved from some proteobacteria and chloroplast has evolved from cyanobacteria.
Answer: osmosis and cellular transport
Explanation: this is 100% just answerd it and got it right
Phytoplankton refers to the microscopic marine species that thrive at the bottom of the food chain. They obtain their energy from carbon dioxide via photosynthesis, like plants and thus are very essential in carbon cycling.
Phytoplankton forms the base of almost every ocean food web. Thus, it can be stated that they make the majority of other ocean life possible. They are the source of food for zooplankton and small fishes, as well as for larger animals like jellyfish and whales.
Thus, if the population of phytoplankton gets declined, it will indirectly affect other species in the aquatic ecosystem. It can also be said that with the decrease in the population of phytoplankton, the population of other major species in the ecosystem also gets a decline.
Answer:
The correct answer is option A. "Advantageous alleles do not arise on demand".
Explanation:
One of the most common misconceptions of how evolution occurs is that an organism is able to develop advantageous traits on demand. Believing that, for instance, a giraffe was able to develop a large neck because it wanted to reach large trees. This is wrong, evolution is the product of nature selecting random mutations that are advantageous to a species.
Answer:
a) Met - Ser - Asp - Trp - Tyr
b) Met - Ser - Asp - Trp
Neutral mutation (which is caused by a type of single gene mutation called a substitution mutation)
Explanation:
After the substitution of A to C, the amino acid codded for stays the same so this is known as a neutral mutation.
