Answer:
Explanation:
Bacteria capsule contain poly-γ-d-glutamic acid and also possesses antiphagocytic properties .
Gram positive cell wall peptidoglycan.
Fimbriae contain adhesin which make them to attach to a base and counter shear force and obtain food.
Pili contain oligomeric proteins which is hair like structure.
Endospores consists of DNA, ribosomes and dipicolinic acid.
RIBOSOMES consist of ribosomal RNA and proteins.
Plasmid consist of circular DNA.
Plasma membranes consist lipid bilayer.
The correct answer is: The speed of sound is faster in the water than in the air.
The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.
They are said to be “denser” than air. what happens is that light slows down when it passes from the less dense air into the denser glass of water. this slowing down the ray of light also causes the ray of light to change directions. it is the change in the speed of the light that causes refraction.
The answer is False. Stalagmite is a cone-shaped <span>deposit of calcite that builds up on the floor of a cave.
