Answer:

primary; counter; Gram-positive; Gram-negative

Explanation:

The illustration is about the <u>Gram-staining procedure.</u>

<em>The procedure is used to distinguish between the bacteria that have a thick cell wall capable of retaining the color of a dye (Gram-positive) or otherwise (Gram-negative). </em>

A smear of the bacterium to be tested is heat-fixed to a clean glass slide after which a suitable primary stain is added, allowed to stay for a few seconds, and rinsed. A mordant is then added, rinsed before a counter-stain is added, and also rinsed. The slide is then allowed to drain off water and then viewed under the microscope using the oil immersion. Gram-positive bacteria will appear blue or purple, taking up the color of the stain while Gram-negative bacteria will appear red under the microscope.

What membrane activities requires energy from atp hydrolysis?
NikAS [45]

Answer:

active transport, like Na + ions leaving the cell

Explanation:

The active transport requires an energy expenditure to transport the molecule from one side of the membrane to the other, but the active transport is the only one that can transport molecules against a concentration gradient, just as the diffusion facilitated the active transport is limited by the number of transport proteins present.

Two major categories of active, primary and secondary transport are of interest. The primary active transport uses energy (generally obtained from ATP hydrolysis), at the level of the same membrane protein producing a conformational change that results in the transport of a molecule through the protein.

The best known example is the Na + / K + pump. The Na + / K + pump performs a countertransport ("antyport") transports K + into the cell and Na + outside it, at the same time, spending on the ATP process.

The secondary active transport uses energy to establish a gradient across the cell membrane, and then uses that gradient to transport a molecule of interest against its concentration gradient.

What are the phases of mitosis and meiosis and what do they do?
ehidna [41]
Prophase
Metaphase
Anaphase
Telophase

Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>

azamat

Answer:

See below

Explanation:

1. Yes, the MNI ought to be changed in light of the revised inventory. Since 4 of the 6 femora are right sided, they would belong to different individuals, so the MNI would now be stated as 4.

2. The sheriff would be told that the possibility of suspecting 22 individuals is very narrow, though not impossible. It is also unlikely that the victims are numbered less than 4 in accordance to the bones found.
