Answer:
- Water entered the potato strips because the potato cells contained higher concentration of solutes than its external environment.
- The solutions are hypotonic to the solution in the potato cells.
Explanation:
According to osmosis, water will move from a region where it is high in concentration to that region where it is low in concentration. However, a region with high solute concentration contains a low water concentration and vice versa.
Hence, according to this question, water is said to move into potato strips from solutions of molar concentrations like 0.0M, 0.2M etc. Water moved into the potato strips because potato cells contained higher concentration of solutes than its external environment. This means that the external solutions are HYPERTONIC i.e. low in solute concentration to the solution in the potato strips.
The flow of energy in an ecosystem is best described as energy moving in one direction from the sun to the producers then to the consumers.
Explanation;
Energy flow is the amount of energy that moves through successive trophic levels of a food chain in an ecosystem. Ecosystem maintain themselves by cycling energy and nutrients.
The energy from sunlight is taken up by producers which use it to produce organic compounds through photosynthesis. The energy is then passed successively to the trophic levels, that is from the producers to the consumers ( primary, secondary, tertiary and quotienary consumers). During this transfer some energy is lost at each trophic level in form of heat.
Answer:
A
Explanation:
The correct formula for cellular respiration is:
Glucose (sugar) + Oxygen → Carbon dioxide + Water + Energy (as ATP).
<h3><u>Answer;</u></h3>
produce a layer of enzyme laden mucus that captures dirt and destroys inhaled bacteria
<h3><u>Explanation;</u></h3>
- Secretions from the highlighted glands <em><u>produce a layer of enzyme laden mucus that captures dirt and destroys inhaled bacteria </u></em>
- <em><u>During inhalation airt that contains dust particles or bacteria or other microorganisms may enter the air ways. </u></em>
- <em><u>The layer of the airway covering the airways, is rich in antimicrobial compounds and mucins that are responsible for removal bacteria and other microorganisms from the airway .</u></em>
- <em><u>This layer consist of mucus that traps, kills, and also inactivates the bacteria. </u></em><em><u>It also contains periciliary fluid which keeps mucus at optimum distance from the underlying epithelia, to enhance bacteria clearance and the motility of cilia.</u></em>
Many metabolic prpcesses depend on water such as electron transport chain and glycolysis
