Answer/Explanation:
Mycoplasma pneumoniae is a gram negative bacteria, meaning it cannot be visualized through gram staining.
However, they can be visualized via a simple DNA stain, such as DAPI or Hoescht.
Answer:
B) slow- twitch, intermediate- twitch, fast-twitch
Explanation:
The three types of muscle fibers are:
- <u>Slow-twitch: </u>they are also called Red Fibers because of their color or type I. These type of fibers are resistant to fatigue, that means that they can contract for long periods, but its contraction is not very strong. Muscles that maintain our posture, such as our back muscles, have a predominancy of these types of fibers.
- <u>Fast-twitch fibers</u>: they are also called type II, or White Fibers because of their color due to the low supply of blood. They are fibers that contract very fast and are not resistant to fatigue. These types of fibers can generate higher amounts of force in a short period, but their contraction is for a short period. They are present in our eye's muscles.
- <u>Intermediate twitch fibers:</u> they characteristics are between the two types of fibers mentioned above. That is to say, that they do not contract as fast as fast-twitch fibers do but not as slow as slow fibers either, also, they fatigue quickly but nos as quicky as fast-twitch fibers or as slow as slow-twitch. They are in the majority of our muscles.
Answer:
As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.
Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.
Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.
Answer:
<em>The correct option is A) swamp sediments</em>
Explanation:
Swamp sediment can be described as a wetland which is located near to a forest. The sediment soil will have adequate amounts of minerals and nutrients in it to support the growth of plants. There will be more chemical compounds present in such type of soil. Hence, option A is correct.
Other options, like option D, is not correct because a desert will have soil which will have very little chemical compounds in it. The soil present in deserts will not be rich in chemical compounds. Usually, the soil in a desert is just sand.
In cellular respiration, oxygen is combined with products fromglycolysis to release energy for the the re-attachment of a phosphate of ATP from ADP and P. Glycolysis provides only enough energy to reattach 2 molecules of ATP where aerobiccellular respiration provides enough energy to reattach 36 molecules.
