Answer:
C. Maximum power point tracking.
Explanation:
A. Direct current: It is also called DC in which electric current flows consistently in one direction.It is used in batteries and cells.It is not used in solar system .Therefore, it is false.
B. Alternating current : It is also called AC . The AC is used in domestic electricity.The current in which direction of electron is reversed after at regular intervals .It is not used for solar cells.Hence, it is false.
C. Maximum power point tracking:It is also called power point tracking. It is used in charge control in solar cells.it is a technique which is used to extracting maximum available power from PV ( photovoltaic cells) solar system.It is a technique that is used to adjust load connected to solar cells and increase their energy output.Therefore, it is true.
D. Electromagnetic induction:It is a process for producing EMF due to change in magnetic field. It is not used in solar system. Therefore, it is false.
Answer:C. Maximum power point tracking.
Answer:
B It occurs in animal cells, but not in plant cells. this is the answer
hope it helps :)
Answer:
- A Tongue-shaped structure called radula for grasping food --> Mollusca
- Fleshy lobe-like structure called parapodia --> Annelida
- Spongin fibers or spicules for support ---> Porifera
Explanation:
Radula: This is an organ used in feeding by mollusks. It constitutes a highly developed feeding organ. The radula has is conformed of small teeth-like structures located in rows. Lateral teeth vary in shape and size. The movements of the radula during feeding are complexes acting as a scratcher on the surface to get the food.
Parapodia: These are characteristic lateral appendixes that emerge and extend from each of the body segments of invertebrates such as polychaetes. The typical parapodium is a fleshy prolongation more or less laterally comprised and is composed of a superior branch (notopodium) and an inferior branch (parapodium).
Spicules: Sponges (Poriferous) skeleton is composed of calcium carbonate and siliceous micro-structures called spicules. Their morphology is so varied that it is used in taxonomy for identification and classification.
There are different kinds of spicules:
- Monoaxonic spicule: needle-shaped, straights or curves
- Tetraxonic spicules: they have four prolongations
- Triaxonic or Hexaxonic spicules
- Poliaxonic spicules
Two terms can be applied to any of these spicules kinds:
- Megaspicules: They are elongated and compose the main architecture of the sponge skeleton
- Microspicules: Variable in shape and size, with ancillary functions
Sponges have few predators because of the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.
Answer:
breathing, sweating, and digestion(look at explanation)
Explanation:
Your body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it's important to rehydrate by drinking fluids and eating foods that contain water.
