Answer:
Virus.
Explanation:
Viruses can't reproduce without invading the cell of another living being.
They are also describe as a plant with naked seeds because during pollination ovule is not enclosed by the carpel except some kind of scales during development .....In contrast the angiosperm have evolved flower hence they are also called flowering plants
Muzzle velocity is a vector quantity which means it has direction and magnitude. Generally speaking, any velocity is classified as a vector quantity, a value with direction and magnitude. Velocity is the rate of change of the location of the object moving and is specified by its direction and speed. Since muzzle velocity is a velocity then it would surely be a vector quantity. Muzzle velocity is the speed of a bullet as it is leaving a muzzle of a gun in a the direction where the gun is pointed. It would have a value ranging from about 120 m/s to 370 m/s in muskets to 1200 m/s for modern rifles.
I believe the correct answer among the choices presented above is the last option. It is in the Sahara desert that most-likely there is physical water scarcity. This is because it is a desert and it is a characteristic of a desert to have very small or no amount of water. Also, the climate their is very hot.
Answer:
Lysozyme in the body fluid protects us from bacterial infection by damaging the cell wall of bacteria which ultimately kills the bacteria.
The bacterial cell wall is made up of NAG and NAM units which is joined by β (1-4) glycosidic bond. Lysozyme attacks on this bond and breaks it causing the damage in the cell wall of bacteria which leads to the death of bacteria.
Archaeal cell wall do not contain β (1-4) glycosidic linkage, it contains β(1-3) glycosidic linkage in its cell wall between NAT and NAG unit and lysozyme do not able to break β(1-3) glycosidic linkage between them so lysozyme do not cause any harm to the archaeal invaders.
