A scientific argument will be considered invalid if the evidence supporting the argument is based on independent data.
If you are only referring to a single scientist or a single study conducted on a certain topic, it means that it hasn't been researched enough for the argument to be reliable. Every scientist needs to refer to other studies and other scientists and their work if they want their arguments to be valid.
The answer is; When the planet is at A it is moving faster than at B.
This is because when the planet is closer to the sun at point A, it is experiencing a stronger gravitation, by the sun, pull than at point B. Therefore, its acceleration due to gravity at point A is higher than at point B.
The cytoplasm contains organelles. The organelles in this list surrounded by the cytoplasm would be the endoplasmic reticulum, lysosomes, and vacuoles. The cell wall and cell membrane are outside the cytoplasm. The nucleus would also be considered in the cytoplasm. If it's talking about a human cell, then chloroplasts would not be in the cytoplasm. Only in plant cells.
Answer: B/C/E/F and possible A if its talking about a <u>plant cell</u>
Answer:
how the narrator feels about the battle.
Explanation:
The first-person point of view is one of the methods used as a medium for telling the story. In this method, the story is told from the point of view of the person who is a character. All the other characters, events, and settings of the story are told from the narrator's point of view. The story is narrated by using the first person pronouns 'I' and 'we'.
In the given excerpt, the first point of view has been used for storytelling. The narrator tells about the experience he underwent on January 8, 1815. He tells about his feelings about the battle.
Answer:
The correct answers are:
A) Antigen-presenting Cell - both responses.
B) Plasma Cell - humoral immune response.
C) Memory Cells - both responses.
D) Antibodies - humoral response.
E) B Cells - humoral immune response.
F) Helper T Cells - both responses.
G) Cytotoxic T Cells - cell-mediated immune response.
Explanation:
Acquired immunity involves both a humoral immune response and cell-mediated immune response, since these two responses are not independent of each other, but instead "work together" in order to perform a better response.
Humoral immunity is mediated by macromolecules (like antibodies) found in extracellular fluids, and <u>is activated much more quickly than the cell-mediated one</u>, but it doesn't last as long. The Cellular immunity, on the other hands, <u>needs the prior activation of cells such as macrophages and lymphocytes</u>.
