Answer:
Depolarization.
Explanation:
The electric membrane potential or cell potential may be defined as the difference in electric potential inside and outside of the cell. The membrane potential is important for the generation of action potential.
The opening of sodium channels in the membrane neuron causes the influx of sodium ions in the cells. This changes the membrane potential towards more positive and the cells depolarize.
Thus, the correct answer is option (A).
A reddish tinge in the cerebrospinal fluid indicates that there is internal bleeding, or hemorrhaging, or is a sign of spinal cord obstruction.
The cerebrospinal fluid (CSF) is a clear, colorless fluid found in the brain and spinal cord. The main function of this fluid is to cushion the brain and spine from impacts and blows and protect these vital components of the body.
Producers bring energy into the ecosystem by making organic molecules from sunlight or chemical compounds. Producers bring new energy into an ecosystem by breaking down inorganic materials and making new ones.
Answer:
15/16 or 93.75%
Explanation:
<em>The proportion of the offspring of the cross expected to be red would be 15/16 or an equivalence of 93.75%.</em>
Red fruit color is conditioned by the presence of A_, B_ or A_B_ alleles. In the absence of both dominant alleles, the condition is white. AaBb was crossed with AaBb.
AaBb x AaBb
Progeny' Genotype Phenotype
1 AABB red
2 AABb red
2 AaBB red
4 AaBb red
1 AAbb red
2 Aabb red
1 aaBB red
2 aaBb red
1 aabb white
Hence, the proportion of the offspring that are expected to be red is 15/16 or 93.75%.

Answer:
Law of original lateral continuity
Explanation:
The law of original lateral continuity basically explains that sediments spread out laterally and continuously until the sediments run out or depending on the limits of the basin (in other words, what catches it). As it extends outwards the layer starts to thin out. This was proposed by Nicolas Steno, who also proposed the law of superposition and original horizontally.
