Rotifer’s cilia draw a vortex of water into its mouth and the rotifer then sifts the food
Answer: D - all of the above
Explanation:
Cytosine (C) is paired with Guanine (G) according to the base pair rule just as Adenine (A) is paired with Thymine (T).
The sugar in DNA is deoxyribose which is a modified form of ribose(also sugar). It simply is a ribose sugar which has lost an oxygen atom hence “deoxyribose”. Deoxyribose is one of the components that make up the DNA backbone.
Hydrogen bonds exist between bases. The importance of these hydrogen bonds is to hold the complementary strands of DNA together.
Answer:
Organnelle
Ribosomes
Nucleus
Archaeabacteria
Phospholipid bilayer
Lipases
Explanation:
1. Organnelles are specialized structures in a cell designed to perform a particular function that will make the cell normal e.g. ribosome, Chloroplast, mitochondrion are examples of organnelles.
2. The Rough Endoplasmic Reticulum (RER) is one of the two endomembranous systems in the cell. It is characterized by its rough appearance which occurs as a result of ribosomes attached to its surface. This attachment of ribosomes makes its function related to protein synthesis.
3. Nucleus is a membrane bound organnelle found only in EUKARYOTIC cells. It houses the genetic material (DNA) of a cell and acts as the brain by directing all of the cellular activity of that cell.
4. Archaeabacteria is one of the six kingdoms in the hierarchical classification of living organisms. They contain unicellular and prokaryotic organisms that are uniquely characterized by their ability to survive extreme conditions e.g high temperature.
5. The plasma membrane is an outer covering that bounds the cells of both Prokaryotic and eukaryotic organisms. According to the fluid mosaic model that describes the structure of the cell membrane, it contains a phospholipid layer that confines its selective permeability upon it i.e. ability to control what goes in and out of the cell. This is due to the amphipathic nature of the phospholipid i.e. contains an hydrophobic and hydrophilic region.
6. Lipases are enzymes that are involved specifically in the breakdown of lipids and fat molecules into fatty acids and glycerol.
Essentially, when you breathe in the lung take in oxygen and pass it along to the bloodstream, which brings it to your bodies cells. In return it picks up carbon dioxide, which the lungs dispose of. Every time you breathe this process is happening. That is why it's crucial to keep your lungs healthy.
