The correct answer for the given statement above would be option D. The statement that correctly answers whether the question of alien life on the moon is scientific is, the question is scientific because it is testable and verifiable. Testable and verifiable in a way that it is possible to conduct tests or experiments to prove whether the given claim is true or not. A scientific statement is based on objectivity. As long as it is not based on personal interests, values, community bias or personal perspectives, it is considered as a scientific statement.
The correct answer is C. Hornworts
Explanation:
The stomate refers to a type of small pores in some plants that allow carbon dioxide and oxygen to enter to the plant and therefore support the exchange of gases in the plant which is necessary for different vital processes. This pores create a complex structure and have specialized cells that support its function. Additionally, this structure can be found in the sporophyte phase of pants which is a stage in the life of some plants including hornworts that have long horn-like structures that contain the stomate. But this cannot be found in other plants such as liverworts or Charales. Considering this, it can be concluded the group of plants in which stomata appear is hornworts.
Answer:
Explanation:
Muscle contraction is stimulated by the movement of an action potential moving along a nerve fiber to the muscles. This event follow some series of process before being stimulated.
1. The impulse arrives at the synapse and travels through the transverse tubules.
2. The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.
3. Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.
4. Tropomyosin molecules bind to exposed active sites, linking actin and myosin.
5. Thin filaments are pulled over the thick filaments.
6. The muscle fiber shortens and contracts.
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.
Mitosis occurs in every cell of the body except in germ cells which are produced from meiotic cell division.
