Value of pi = 3.14
Radius of the semicircle = 6 cm
Diameter of the semicircle = 6 * 2 cm
= 12 cm
Perimeter of a semicircle = pi * Diameter *(1/2)
= 3.14 * 12 * 1/2
= 3.14 * 6
= 18.84 cm
From the above deduction, we can conclude that the perimeter of the semicircle in question is 18.84 cm. I hope that this is the answer that has come to your desired help.
Answer:
this is how proteins are bound, through a series of amino acids combined in a chain
Explanation:
The statement is true, the competitive exclusion principle states that two organisms cannot fill similar niches.
Amoeba are the consumers that surround, engulf, and ingest their food.
<h3><u>Explanation</u>:</h3>
Amoeba is a unicellular organism that belongs to the kingdom Protista. This organism are having eukaryotic cells without any cell walls. These organisms have each and every cellular organelle that are needed to perform metabolism.
Amoeba are consumer in mode of nutrition. Whenever they senses some food, they push a part of their cytoplasm packed in cell membrane towards the food to cover it. This process is called pseupodia.
This pseupodia engulfs the food and performs phagocytosis or pinocytosis. This food is covered in a cell membrane inside the cytoplasm which is called the food vacoule or endosome. This then fuses with a lysosome to digest and then the excretory product is let off by the secondary vacoule.
Lipids are stored as triacylglycerols and waxes on both animals and plants
<h3>What is lipids ?</h3>
Lipid can be described as an organic compound that is not soluble in water. lipid is an essential component that is needed for proper functionality in both plants and animals.
In plants, lipids help provide lots of energy that is needed for different metabolic processes that goes on in the plant. Lipids also help fight off pathogens in plants
In animals, lipids also serve as an energy source and they help in the regulation of the different hormones present in the body. Lipid also help signal important molecules when they are required in the body and they also help in the proper digestion of food molecules.
