Answer:
The (Receptive) segment includes both dendrites and the cell body, which are the regions of the neuron that receive stimuli to excite the neuron. Channels in this region are (Gated chemically) ; no significant numbers of (Voltage gated) channels are present.
• The (Initial) segment is composed of the axon hillock. This segment contains voltage-gated channels.
• The (Conductive) segment is equivalent to the length of the axon. It contains voltage-gated channels.
• The (Transmission) segment includes the synaptic knob and contains voltage-gated channels and (Pumps) .
The answer is D. Global warming causes the ocean temperatures to rise and also its pH to decrease due to increased dissolved carbon dioxide in the waters. Due to the unfavorable temperatures and pH, the algae dissociate from the symbiotic relationship with coral polyps (as a survival mechanism) hence leaving the coral white (coral bleaching). The symbiotic relationship is key for the survival of the coral polyps hence most die following the dissociation. This upsets the reef ecosystem and affects all aquatic organisms that depend on the reef.
Answer:
5: The phenotype for both parents is being tall.
6: 25%
7: 50%
8: 25%
Explanation:
5: We are shown that tall plants are dominant over short plants, and the genotypes of both parents are Tt (tall, short). This means that both parents will be tall.
6: The Punnet Square shows us that 1 out of 4 offspring are TT, 1/4 is 25%
7: The Punnet Square shows us that 2 out of 4 offspring are Tt, 2/4 is 50%
8: The Punnet Square shows us that 1 out of 4 offspring are tt, 1/4 is 25%
The key difference between age polyethism and reproductive division of labor in honey bees is their age and functions, younger bees work inside the honeycomb, they have several duties, such as feeding the larvae, cleaning, thermoregulate the inside and receiving the nectar from the older bees, through trophalaxy (mouth contact), those bees are in charge of the guard an cleaning of the outside, besides helping with the honeycomb ventilation.
One of the functions of the gallbladder is to store bile. The bile in the gallbladder tends to be excess from the liver, and is used throughout the digestion process.
Fun Fact: While the gallbladder aids in digestion, it is not required, and humans can survive without it!
