Answer:
The correct answer is e. Golgi apparatus
Explanation:
Golgi apparatus are also known as Golgi bodies and it bound by only a single membrane. It is present near the endoplasmic reticulum in the cell. Golgi apparatus is composed of 5-8 membrane-bound sac-like structures called cisternae.
The Golgi apparatus plays important role in the modification of molecules like proteins and lipids. The unprocessed proteins that are released from the endoplasmic reticulum enter the Golgi apparatus and in the Golgi apparatus its modification like glycosylation and phosphorylation occurs.
Then these processed proteins are released outside from the Golgi in vesicle forms which have a signal molecule that guides it to various locations in the cell or towards the plasma membrane from where it can move out of the cell.
Therefore the correct answer is e. Golgi apparatus.
<u>Answer:</u>
<em>There are innermost serious membranes that cover the heart is Parietal Pericardium.</em>
<u>Explanation:</u>
Heart is <em>covered by pericardium</em> in two sides, inner and outer sides. The inner membrane is parietal pericardium and the outer one is visceral pericardium. Pericardium is made up of <em>fiber tissues</em> that strongly protect the heart from all around.
The<em> main function of pericardium</em> is to protect the heart from any injuries and prevent the infections. The serious pericardium helps in<em> lubricating the heart. </em>
A waterborne pollutant can have different effects on aquatic life depending on the nature of the pollutant. A pollutant at lower levels can have minimal or no effect on aquatic life. However, when the concentrations of the pollutant are high, the population of aquatic organisms can be greatly reduced. There are also times when pollutants at lower concentrations cause significant damage. An organism can consume another organism that has absorbed small amounts of the pollutant. As the consumer takes in more of the contaminated organism, the pollutant is magnified in the body of the consumer resulting in lethal concentrations. This is called biomagnification.
The population of frogs would exhibit competition due to the limited resources in the lake. Competition can be defined as the interaction among the species of organisms when resources are limited in an ecosystem. The type of competition observed in the above example of the lake with limited resources is called intraspecific competition as it is between the members of the same species competiting for the same resources. The species that do not compete will eventually die or get eliminated. This results in the change of population of frogs over time. Thus, competition is one among the forces that is responsible for natural selection.
Answer:
All the different plant populations make up the plant<u><em> community</em></u> in this swamp. The plants are part of the bigger <u><em>ecosystem</em></u>, that contains many biotic and abiotic factors.
Explanation:
In ecological studies a community can be described as a different population of species that live in an area at a specific time. For example, different kinds of plants and animals living in an area at a particular time.
In ecological studies, an ecosystem can be described as a community possessing both its biotic and abiotic factors. For example, all the animals, plants, decomposers of a community along with abiotic factors like water, soil sunlight etc.
