Prokaryotic bacteria are surrounded by a cell membrane that contains the transport proteins to regulate the entry and exit of materials through the cell, the cell wall to help maintain cell shape and structure, and the capsule, which aids against drying out and protects bacteria from a host's immune system.
<h3><u>Explanation:</u></h3>
Bacteria are the prokaryotic organisms that are found in every part of Earth. These organisms do have an interesting ultrastructure. The coverings of the bacteria are three in layer. They are
A. The outer capsule.
B. The middle cell wall.
C. The inner cell membrane.
The capsule is the outermost covering of bacteria that is formed of different slimy materials. These materials contains hygroscopic substances which can absorb water from the surroundings even when the water concentration in outside is very very low. This layer of protection outside bacteria help them to protect themselves against drying out at dry conditions.
The middle cell wall is formed of polymers of N acetyl glucosamine and N acetyl muramic acid. This layer is chitin in nature and is strong enough to maintain the shape and size of bacteria irrespective of outer conditions.
The innermost layer of bacteria is cell membrane which is formed of proteins and lipids bilayer and this cell membrane contains different transport for proteins which help in transport of different substances like water and nutrients inside the cell by means of active transport or passive diffusion.
Answer:
B
Explanation:
Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is thought to be the most common type of ecological interaction, and it is often dominant in most communities worldwide.
Point suspension occurs when one receives too many points against driving record within a given period of time, therefore one will end up loosing his/her driving licence through an accumulation of excess points. This happens such that each time one is convicted of a driving violation the court notifies the DMV (division of motor vehicles) electronically thus keeping truck on the number of times one has made such violations. Therefore, it is true that rough estimates that point suspension of the driver's license can average between $3,000+ to $11,000+.
It’s ADH
Antidiuretic hormone (ADH) is a chemical produced in the brain that causes the kidneys to release less water, decreasing the amount of urine produced.
