PLEASE I need help so badddd

Answer:

Explanation:

Only archaebacteria are capable of methanogenesis

Archaebacteria who use other forms of cellular respiration also exist, but methane-producing cells are not found in Bacteria or Eukarya.

Unique cell membrane chemistry. Archaebacteria have cell membranes made of ether-linked phospholipids,

Water flows toward the hightides, halfway between them causing lowtides. The correct option is A.

What is a high tide?

They are caused by the moon's and, to a lesser extent, the sun'sgravitationalforces on the earth.

A high tide occurs when the highestpoint of the wave, or the crest, reaches a coast. A low tide occurs when the lowest point, or the trough, reaches a coast.

Water flows toward the hightides halfway between the high tides, causing lowtides. The moon's gravity pulls slightly stronger on the water on the side of Earth closest to the moon than on the entire Earth.

This difference results in a bulge of water on the Earth's side closest to the moon.

Thus, the correct option is A.

Explanation:

The importance of mitosis in the root tip is that it helps the growth of the root; as a result, the root can grow more and absorb more nutrients from the soil, which helps the plant grow further.

What is the role of mitosis?

Mitosis is a process in which the cell divides equally and both the parent cell and the daughter cell look alike. In this process, the plant root grows during mitosis, the old cell is replaced by the new cell, the cut is filled, and so on.

The mitosis completes in five steps, such as the prophase, metaphase, anaphase, telophase, and cytokinesis, where the cell faces many changes, such as the nuclear envelope dissociating and the cytoplasm of the cell dividing. The mitosis is the result of the body size growth that is seen in the child, and this is the result of the mitogens.

Hence, the importance of mitosis in the root tip is that it helps the growth of the root; as a result, the root can grow more and absorb more nutrients from the soil.

Answer:

The serial dilution can be done by half- logarithmic dilution method.

Explanation:

• This is also called the Ten-fold dilution method.
• The process involves the following steps, and the volumes represented are arbitrary.

1. From the concentrated solution of the disinfectant take 1 ml of disinfectant in a falcon tube. 9 ml of water is added to that. Here we get a solution which is   diluted.
2. Take 1 ml of the above diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is   diluted.
3. Take 1 ml of the above diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is   diluted.
4. Take 1 ml of the above diluted solution in another falcon and add 9 ml of water to it. Here we will get a solution which is   diluted.

Final answer:

To prepare a serial dilution, you start with the stock solution and dilute it step-by-step. For a 1/20 dilution, take 1 part solution and add 19 parts solvent. For a 1/40 dilution, dilute the 1/20 solution further by taking 1 part of the 1/20 dilution and adding 1 part solvent. Similarly, for a 1/80 dilution, take 1 part of the 1/40 dilution and add 1 part solvent.

Explanation:

To prepare a serial dilution, you start out with a stock solution (in this case, the disinfectant) and dilute it step by step. To prepare the 1/20 dilution, you take 1 part stock solution and add 19 parts solvent. Then for a 1/40 dilution, you can dilute the 1/20 solution by a further factor of 2: take 1 part of the 1/20 dilution and add 1 part solvent. The same principle applies for the 1/80 dilution: take 1 part of the 1/40 dilution and add 1 part solvent, or you could take 1 part of the original stock solution to 79 parts of solvent.
