In which phase do sister chromatids line up in the middle of the cell, (in 'single-file', without a homologous partner)? Group o
ipn [44]

Answer:

The correct answer is ''METAPHASE I.''      

Explanation:

Metaphase I is the stage in which chromosomal studies are generally performed, because its morphology is very clear. The chromosomes, moved by the mitotic spindle, are placed in the center, between the two asters and form the so-called metaphase plate, in which the chromosomes are positioned in such a way that the kinetochore of each sister chromatid are oriented towards the opposite poles. Keeping chromosomes on the cell equator implies a balance between the forces of the microtubules that tend to move the kinetochores toward opposite poles, so positioning them in the center involves a great deal of energy.In each kinetochore, between 20-30 microtubules can be anchored, which exert traction force towards the pole from which they come, so the metaphase plate is maintained by the balance between the opposite forces of the poles on the chromosomes, which hold their sister chromatids by centromeric cohesin.

Maintenance of normal intracellular fluid volume depends largely on the intracellular concentration of _____ ions.
kogti [31]

The answer is D. Extracellular, the main ions involve in osmoregulation in a cell are sodium and chloride. Intra-and extracellular distribution of K+ is influenced, for example, by Na+/K+-ATPase function, pH, Cellular catabolism and anabolism, Insulin and glucose. Parathormone and calcitriol are important in the homeostatic regulation of phosphates.

What should you do if you need to leave the laboratory temporarily in the middle of your work?
kondor19780726 [428]

While leaving the laboratory temporarily in the middle of your work remove your lab coat and gloves.

<h3>Laboratory safety:</h3>

Washing your hands is the final thing you should do before leaving the lab after an experiment. Since most chemicals are somewhat harmful, wash your hands before you leave. After taking the necessary measures, inform the teacher.

With its risky processes, hazardous chemicals, and fire threats, the science laboratory is inherently unsafe. Avoid coming into contact with chemicals directly. Never taste, smell, or inhale lab chemicals. After taking off your gloves and before leaving the work area, wash your hands and arms thoroughly with soap and water. In a laboratory, never consume food or liquids, chew gum or tobacco, light up, or use cosmetics. These fundamental safety offer guidance on conduct, cleanliness, and safety to prevent laboratory mishaps.

With reference to the induced fit model, describe how the tertiary structure of a named enzyme facilitates its function as a bio
Olenka [21]

The induced-fit model includes the change in the conformational site of the substrate and enzyme. It is done till the enzyme completely binds the substrate. This will then activates the enzyme to perform its work.

<h3>What is induced fit theory?</h3>

Induced fit theory or model suggest that the activation site of enzymes and the binding site of substrates undergo some conformational changes to fit into each other.

This binding results in activation of the enzyme and as the enzyme has a three-dimensional tertiary structure, this would help it to get fitted into the substrate.

Thus, with reference to the induced fit model tertiary structure of enzyme facilitates its function as a biological catalyst.
