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: It converts carbon to oxygen
Explanation: During photosynthesis, plants create glucose and oxygen molecules
It states that, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature, assuming in a closed system.
p1/t1=p2/t2
The answer is <span>2.4 weeks
</span>
<span>x - the time in weeks
y - the heights of the plants in inches
</span><span>When both plants to reach the same height, then yA = yB
</span><span>y = 1.8x + 3.1
</span><span>y = 2.3x + 1.9
</span>2.3x + 1.9 = 1.8x + 3.1
2.3x - 1.8x = 3.1 - 1.9
0.5x = 1.2
x = 1.2 : 0.5
x = 2.4
Answer:
The correct answer will be- the free energy change will be +13 kcal/mol.
Explanation:
The free energy change of a chemical reaction is the measure of the spontaneity of the reaction in which the negative value of free energy represents that reaction is exergonic while positive value represents that reaction is endergonic.
In the given question, if the free-energy change is 13 kcal/mol for the hydrolysis of ATP to ADP + Pi which releases energy used by the cells then reversal of the reaction that is the formation of ATP molecules from the ADP and Pi requires energy which will be the same energy required to break the ATP.
This shows that 13kcal/mol energy will be used but with a positive sign as the energy is needed or the reaction is endergonic.
