Answer: True, both of the given statements are true.
Explanation:
1. Nearly all the environment contains microorganism whether it is soil, air, water or any other surface. They have the ability of live in the extreme conditions.
There are different forms of bacteria found at different places. Some of them are thermophiles that at found in extremely hot conditions such as thermal vents.
The organism like Psychrophiles are the microorganisms that have the ability to survive at lower temperatures. Example: bacteria found in polar regions.
2. A culture can be defined as a pure culture if it has an unadulterated species of bacteria. It has no contamination and if a small inoculum from the pure sample is streaked on a plate then a pure culture of the sample is obtained.
This should be done in an aseptic condition so that the bacterial species should be free from contamination.
Answer:
The correct answer is both pumps use proteins to transport substances across the cell membrane.
Explanation:
Sodium potassium pump helps in the active transport or uphill transport of both sodium and potassium across the cell membrane against their concentration gradient.
Whereas Ca2+ATPase or calcium pump itself is a trans membrane or membrane spanning protein which helps in the transport of Ca2+ outside the cell to maintain electrochemical potential of Ca2+ ions.
The dermal blood arteries work in dermal papillae to hydrate the epidermal cells.
<h3>What are dermal papillae used for?</h3>
The term "dermal papilla" can also be (DP). It is described as the hair follicle of an epithelial progenitor cell's chemical and physical niche. The dermal papilla's main job is to produce the hair shaft and rejuvenate the cycling section of the hair follicle. Dermal papillae are important because they reinforce the bond between the dermis and epidermis and reduce friction-related damage in places that are often used. Moreover, The dermis has a rough appearance thanks to the papillae, which interlocks with the epidermis above it to reinforce the bond between the two layers of skin. The papillae produce epidermal ridges on the palms and soles. These epidermal ridges give rise to fingerprints.

Answer:
Yes
Explanation:
I say yes because with the Earth's "sunscreen" layer waring down, the heat of the sun; even if the hole was in the north pole, could overheat the earth causing a change in all environments including the desert.
Explanation:
Significance. The cycle's importance is based on the prevention of lactic acidosis in the muscle under anaerobic conditions. However, normally, before this happens, the lactic acid is moved out of the muscles and into the liver. The cycle is also important in producing ATP, an energy source, during muscle activity.
