describe some home or business technologies that use spectrometric equipment to analyze the atmosphere or temperature.

Answers

Some home/business technologies that use spectrometric equipment are ;

Home security systems like fire alarms and Air conditioning system

The fire alarms and air conditioners found in our homes are triggered when the temperature of the atmosphere changes from been too cold to been too hot or vice versa.

Home technologies that respond to changes in the environment or atmosphere are equipped with some level of communication technology which enables them to respond to changes in the environment via automation. The communication technology found in these home appliances makes use of spectrometric equipment ( measures changes of light wavelength across the electromagnetic spectrum )

Hence we can conclude that Some home/business technologies that use spectrometric equipment are ; Home security systems like fire alarms and Air conditioning system

In which situation would osmosis most likely occur

Answers

Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane. A selectively permiable membrane is one that allows unrestricted passage of water, but not solute molecules or ions.

The case in which osmosis occurs is that when there is a selective permeable membrane is present and it allows only selective substances to pass through the channel.

What is osmosis?

Osmosis is the process in which molecules of the solvent pass via a semipermeable membrane from a lower concentrations to higher concentration or from less concentrated solution to high concentrated solution. In the process of osmosis movement of water takes place.

There are mainly three types of osmosis and these are hypertonic, hypotonic, and isotonic. The process of osmosis is passive transport as water moves from low solute concentration to high solute concentration.

Osmosis is also known as diffusion of water or solvent via a membrane which allows only selective substance to go across the channel. The process of osmosis does not require ATP because it is a passive process.

Therefore,The case in which osmosis occurs is that when there is a selective permeable membrane is present and it allows only selective substances to pass through the channel.

9. What does a pyramid of energy show about the amount of energy available at different trophic levels of a food chain?



10. Why do different trophic levels have different amounts of energy?

Answers

Answer:

A food web can be formed by more than one food chain, since the webs includes all possible interactions that can occur between individuals of different trophic levels.

Explanation:

Based on the scheme shown in the image

1. How many food chains make up the food web?

This food network is made up of three food chains

Plant → Bird → SnakePlant → Insect  → Bird → SnakePlant → insect → Frog → Snake

Food webs often include several food chains, since they are due to the interaction between organisms at different trophic levels, which actually happens within an ecosystem.

2. Which organism is an herbivore?

In this case, both the insect and the bird are herbivorous organisms, since they feed of the producer, which is the plant.

3. Which organism is an autotroph?

The only autotrophic organism is the plant, since it is capable of manufacturing its nutrients from sunlight and inorganic matter.

4. Which organism is a third-order heterotroph? To what trophic level does that organism belong?

The third order heterotroph is the snake, since it feeds on other animals.  The snake is a carnivore and can be a secondary or more commonly tertiary consumer, so it can be placed in the 3rd or 4th trophic level.

5. Which organism is an omnivore?

According to the scheme proposed, the bird is omnivorous, since it feeds on both plants and insects.

6. Which organisms belong to more than one food chain?

In this case, the plant, the insect, the bird and the snake are part of more than one food chain.

Plant → Bird → SnakePlant → Insect  → Bird → SnakePlant → insect → Frog → Snake 7. Which organism belongs to more than one trophic level?

The bird can be located in both the second and third trophic level, being a primary consumer —when it feeds on plants— or secondary, when it feeds on insects.

8. What are decomposers? From which trophic levels are the organisms that decomposers feed on?

Decomposers are generally bacteria and fungi, organisms capable of degrading organic matter, thus enriching the soil. Decomposers can feed on any trophic level.

9. What does a pyramid of energy show about the amount of energy available at different trophic levels of a food chain?

As the ascent of the pyramid occurs —or at the upper trophic level— the amount of energy available decreases. This is because from one trophic level to another only 10% of the energy can be used. If a plant has 5000 Kcal available, the herbivore that consumes it can only use 500 Kcal.

10. Why do different trophic levels have different amounts of energy?

The main reason for the difference in energy in each trophic level is that energy is lost in each one of them, which the organisms use in their metabolism. A consequence of the metabolism is the loss of energy as heat, which is acquired by the environment.

14. f. diffusion

15. a. excreting waste

16. b. exocytosis

17. a, endocytosis

Explanation:

14. The movement of molecules from a high concentration to a low concentration is diffusion. Active transport uses energy to move molecules against their concentration gradient (from low to high). Osmosis specifically refers to water molecules. Endocytosis is the movement of molecules inside the cells via the cell membrane engulfing it.

15. The membrane controls the substances that enter and exit the cell, therefore it is involved in excreting waste products from inside the cell.

16/17 Endocytosis is engulfing substances to bring them inside the cell. Exocytosis is the reverse process, where substances exit the cell by fusing with the cell membrane. The movement of molecules from a high concentration to a low concentration is diffusion.  Osmosis specifically refers to water molecules.

c.The cells of water lily plants get less oxygen from the seawater
d.The cells of water lily plants lose all important nutrients to the seawater


IN A TEST RN!!!!

Answers

answer: a

explanation: osmosis is a process where water moves from a less concentrated solution to a more concentrated one. seawater has more salt than the water inside the lily plant, so this causes the water from inside the plant to move out. without much water inside, the plant begins to wilt.
