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. Loss of Habitat
Explanation:
All other answers would encourage them to populate.
Answer: Plant vegetation so that their roots hold the soil firmly.
Build walls around the farm area.
Add natural fertilizers to the soil.
Soil erosion is a process of removal of top layer of soil which get sediment at some other place due to the affect of agents like wind and water. The superficial upper layers of soil are rich source of nutrients and organic matter and active region for germination of seeds and plant growth. Soil erosion removes these superficial layers making soil less fertile or not fertile and less useful for plant growth.
Plants growing in a vegetation have roots which can hold the soil and will prevent soil erosion from wind and water or any other agent. Building of walls around the farm area will prevent flood water to get inside the farm area and hence, prevents soil erosion by water. Addition of natural fertilizers to the soil adds up nutrients to the soil which facilitate plant growth and plant roots hold the soil therefore, prevents soil erosion.
