Answer:
11 males, 25%
Explanation:
Eleven of the 44 males in this study are taller than 175 centimetres, which makes it one fourth of the total that is 25%. See below:
simplify the fraction
= now multiply it by 100 to convert to a percentage value.
= 25%
Answer:
The correct answer is 10 and this is 50%
Explanation:
A large region of interconnected ecosystems.
A large region of interconnected communities.
A large region of interconnected biospheres.
Answer: A large region of interconnected ecosystems.
Explanation:
Biome is an ecological community that is located in a geographic area which exhibit the habitat for a specific species. A biome can be composed of many ecosystems. For example, aquatic biome may contain distinct ecosystems such as kelp forests and coral reefs.
On the basis of the above description, A large region of interconnected ecosystems.
Answer:
In the presence of lidocaine, the action potential was NOT affected at R1 because lidocaine was applied downstream of R1
Explanation:
Lidocaine is an anesthetic that has the power to neutralize neuromal membranes. This anesthetic power allows the ionic fluxes capable of stimulating impulses to be diffused and this allows a dormancy to be achieved. However, when lidocaine is applied downstream to a molecule or structure, the action potential of that structure or molecule is not affected and it may continue to receive impulses.
Lidocaine does not affect the generation of action potentials because it blocks voltage-gated sodium channels.
In the context of neural signaling, lidocaine often functions as a local anesthetic by inhibiting voltage-gated sodium channels, which are necessary for the propagation of action potentials. If the action potential at R1 was not affected in the presence of lidocaine, it could be due to several reasons. One possibility is that lidocaine was applied upstream or downstream of R1, which would not directly impact the action potential at R1. Another possibility is that there are no voltage-gated sodium channels at R1 to be affected by lidocaine.

Answer:
Guard
Explanation:
The opening between guard (pores) cells is known as stomata. The stomata helps in diffusion of atmospheric CO2 into leaf's interior and also involved in loss of water by plant leaves through transpiration. The opening and closing of stomata is controlled by guard cells.
Guard cells control the opening and closing of stomata by becoming turgid or flaccid because of potassium ions. The water potential decreases by increasing the solute concentration and water always flow from higher potential to lower potential. Remember maximum water potential is zero.
When potassium ions concentration increases inside the guard cells, water follow the potassium ions and guard cells become turgid which cause the opening of stomata. On the other side when the potassium ions concentration decreases inside the guard cells the water leaves the guard cells and guard cells become flaccid causing closing of stomata.
Answer:
Water molecules are joined together by weak Hydrogen bonds.
