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.
The answer is B. (an increase in inbreeding) hope this helped !!
Answer:
evacuate all wildlife from the bay
Explanation:
Algal bloom is a term used to describe the excessive growth of algae species in a water body. This excessive growth or proliferation is as a result of the exposure to nutrient in form of pollutants, a process called Eutrophication.
However, the presence of an algal bloom indicates the pollution of that water body, which will result in the degradation of the pollutants by bacteria. As bacteria acts on the pollutants in the water body, they excessively use the dissolved oxygen of the water body, hence, drastically reducing the oxygen levels of the water. This possess a great threat to aerobic wildlife in the water, which could die as a result of suffocation or anorexia.
Hence, the most important thing to do in a case of noticing an algal bloom in a bay is to evacuate all wildlife from the bay in order to prevent mass death.
Answer:
aluminum: bauxite and corundum
Copper: chalcopyrite
Tin: Cassiterite

Answer:
B. Two functions of carbohydrates are structural support and transferring genetic information
Explanation:
Carbohydrates are synthesized in green plants, thanks to photosynthesis, in which carbon dioxide (CO2) and water are converted into glycides, with energy provided by light. The energy stored in the glucose molecule during photosynthesis is released in the degradation (catabolism) of glucose, producing water and CO2.
From the point of view of metabolism, the main function of carbohydrates in plant organisms is to provide energy and provide structural support. This can be seen in the question above, because we can see that in spring, when stem growth is at its fastest pace, cellulose production rates increase in some plants, while in months with less sunlight, the level of starch decreases in some plants.
