Answer:
Diet includes three materials such as lipids, protein and carbohydrates. Lipids are chemically digested by bile.
Proteins are chemically digested by duodenum.
Carbohydrates are chemically digested by Amylase in the mouth.
Lipids are converted into fatty acid, proteins are converted into amino acid and carbohydrates are converted into glucose.
Vitamins absorption of digestion food across villi and micro villi takes place.
Answer:
The correct answer is option C) "Remora fish stick to large sharks, receiving a free ride and scraps of food the shark does not eat. The shark is neither helped nor harmed".
Explanation:
Commensalism is defined as a type of interspecies relationship at which one individual gets benefited and the other is neither benefited or harmed. An example of commensalism is the one between remora fish and large sharks. In this case, remora fish gets attached to the large sharks by an organ that acts suction cup. The remora fish gets benefited by receiving transportation, a food source and protection from predators, while the large sharks are neither helped nor harmed.
<h3><u>Answer;</u></h3>
The above statement is <u>False </u>
<h3><u>Explanation;</u></h3>
- Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
- <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
- In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.
Answer:
All of their functions are performed by a single cell.
Explanation:
Unicellular are those organisms whose body is madeup of one cell. In Unicellular organisms one cell perform all the functions and activities of the cell such as respiration, digestion, excretion and reproduction. Unicellular organisms reproduce asexually such as binary fission, budding and fragmentation etc. In Unicellular organisms, a single cell is divided into two equal parts and each part becomes a new organism.
