The validity of the hypothesis cannot be confirmed or refuted from only one experiment. By using a series of experiments, the human error or measurement error is reduced to a minimum. Furthermore, more than one factor can be used to determine the validity of the hypothesis.
I will respond to this student that the experiment needs to be repeated multiple times before a conclusion can be drawn! Also, the data will refute or confirm the validity of the hypothesis and not the researcher's own opinion/rational.
Mosses, ferns, and lichens are bryophytes. They are non-vascular and non-flowering plant and have a thallus-like body. They reproduce by production f spores, inside the sporangia, and connceted to a base called as sporangiophore, which attaches it to the thallus.
As a leaf cell is a plant cell contains chloroplasts for photosynthesis which the root hair cell does not have, leaf cell also contains larger vacuoles and the presence of a cell wall.
Answer:
A protein that is destined to be secreted from the cell:
- is targeted to the RER as a soluble protein.
Explanation:
The main function of the RER is the synthesis and transport of secretion or membrane proteins.
If you are looking for the RER you could fount it on eukaryotic cells, side by side of the nucleus, and cover in ribosomes.
Answer:
Option (C).
Explanation:
The dilation of feeder arterioles carry blood directly into the blood vessels. The pre capillary sphincter in the systemic capillary beds can open due to the different factors.
The local release of histamines do not cause the dilation of feeder arterioles and does not cause the opening of systemic capillary beds. Histamine chemical is involved in the immune response of the body.
Thus, the correct answer is option (C).
