Answer:
Cells are placed in a solution that causes them to absorb liquid until they burst. When more water is removed from the solution, newly added cells do not burst. The original solutions was hypertonic solution , while the second was hypotonic solution to the cells.
Explanation:
Answer:
Generally, K+ ions ensures re-polarization of the membrane potential. It always ensures that the neuron returns its resting state, protecting the neurons and ensuring episode of rest before the next action potential.
K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.
Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.
Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.

Answer:
<em>Staphylococcus aureus</em>
Explanation:
According to the rule of binomial nomenclature, the name of the organism is written in two parts that are-
1. Generic name- The first name which signifies the genus of the organism, the word represents the noun of the organism, the first letter of the word is always uppercase that is like in the "Staphylococcus"
2. The specific epithet-the second name of the organism represents the species which is usually a noun, and the first letter of species is always written in lowercase like in the aureus.
The scientific name should be written either in the italicised form or if not possible to write in the italicised form than underline the name.
Thus, <em>Staphylococcus aureus </em>is correct.
Answer:
Option A is the correct answer. To conduct a controlled experiment would be the best choice for Maria to test her prediction.
Explanation:
A controlled experiment can be described as an test in which one of the test models is kept constant for a variable, while in other experimental models, a change is made for testing the variable.
It would be best for Maria to conduct a controlled experiment. In the control model, Maria should keep light as constant whereas in other experimental models she should increase and decrease the quality of light to test her prediction. She should then compare her experimental results with the control model to deduce the results.
<span>Plants without vascular system are non-vascular plants. Non-vascular plants have no xylem and no phloem.
Non-vascular plants include algae, bryophytes, moss grass, liverworts and hornworts.
The answer to this item is moss. Moss is a non-vascular plant which has no seeds and no flowers. It uses spores in reproduction.</span>
