An Asian clam, a fresh water creature, is usually less than 50 millimeters.

It tends to be small and light-colored, with a shell ornamented by distinct, concentric sulcations, anterior and posterior lateral teeth with numerous fine serrations. It resides in brackish to freshwater rivers, lakes, streams, canals and reservoirs. This creature lies on or is slightly buried in materials such as sand, silt, or gravel-bottomed places. It usually prefers running water with high oxygen levels and has no tolerance for polluted or near-freezing water.

For some Gram-negative bacterial infections, antibiotic treatment can cause a more severe reaction than that caused by the base
Anni [7]

Answer:

Polymyxin because, it inserts into the cell membrane and disrupts homeostasis.

Explanation:

Antimicrobial effect reacts with the cell membrane of the gram negative bacteria and causes disruption in their cell membrane by creating pores.

The cell membrane of bacteria release endotoxin for creating defense mechanism.

But the effect of certain antimicrobial peptide disrupt the effect of membrane by releasing electrostatic interaction and creates membrane pores.

The interaction between the microbial peptide and the cell membrane causes disruption of the cell.

Thus polymyxin is used to treat against the gram negative bacteria as they breaks the cell membrane of the bacteria.

Answer:

Figure 3

Explanation:

A mixture is a substance made up of two or more different kind of atoms arranged in such a way that they are not chemically linked or joined. This accounts for the reason a mixture can be separated easily. In the figures attached as an image in this question:

- Figure 1 represents an element because it is made up of only hydrogen atoms chemically bonded together to form a molecule.

- Figure 2 represents a compound because it contains hydrogen and carbon atoms chemically joined together.

- Figure 3 represents a MIXTURE because it contains the oxygen and carbon atoms, which are not chemically joined to one another. As seen in the image, the oxygen atoms are not joined to the carbon atoms.

- Figure 4 represents a compound because it contains oxygen and hydrogen atoms chemically bonded together.

Retrieve your plant specimens. If you have an Edmentum lab kit, your specimens are a cork section, Zea
Tcecarenko [31]

In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.

<h3>How does mitosis occur in plant cells?</h3>

In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.

With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.
