<h3>Economic importance of microbes</h3>
Microbes can be beneficial as well as harmful.
Some of the beneficial importance of microbes include:
- Production of medicine or medicinal products. E.g penicillin
- Conversion of atmospheric nitrogen to usable nitrogen forms to plants, otherwise known as nitrogen fixation.
- Food production. E.g yeast in the production of bread and Lactobacillus in the production of yogurts.
- Bioremediation of pollutants.

#SPJ3
The correct answer is A. Between the visceral and parietal layers of serous membranes
Explanation:
Serous fluid is a type of pale yellow fluid similar to mucus that is secreted by certain membranes to reduce friction in body cavities. This can be found on different organs in the body including the digestive system, for example in the peritoneum that encloses multiple organs in the abdomen. Additionally, serious fluid develops between two main layers: the visceral layer that covers the organs and the parietal layer that follows the visceral layer. According to this, serous fluid reduces friction "between the visceral and parietal layers of serous membranes".
Answer:
Myosin
Explanation:
Two of the important proteins are myosin, which forms the thick filament, and actin, which forms the thin filament. Myosin has a long, fibrous tail and a globular head, which binds to actin. The myosin head also binds to ATP, which is the source of energy for muscle movement
Answer:
I. The nuclear membrane breaks up.
II. Sister chromatids condense.
III. Sister chromatids align on the metaphase plate.
IV. The cleavage furrow forms.
V. Sister chromatids separate.
Explanation:
Mitosis is divided into 5 stages:
- Prophase
- Metaphase
- Anaphase
- Telophase
- Cytokinesis
The prophase stage is marked by two main events
- <em>Dissolution or breakage of nuclear membrane</em>
- <em>Condensation of genetic materials</em>
Metaphase is marked by
- <em>Alignment of chromosomes (made up of two sister chromatids) on the metaphase plate</em>
- <em>Attachment of spindles to aligned chromosomes at the centromere</em>
Anaphase is marked by
- <em>Initiation of cleavage furrow formation</em>
- <em>Shortening of spindle fibers results in the separation of sister chromatids</em>
- <em>Sister chromatids begin migrating to opposite poles</em>
Telophase
- <em>Chromatids completes their migration to the poles</em>
Cytokinesis
- <em>Nuclear membrane reforms</em>
- <em>Sister chromatids decondense</em>
- <em>Cytoplasm divides</em>
Explanation:
<u>-how long it takes for the voltage-gatedNa+ channels to close at the end of an action potential</u>
Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient.
The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential.
