Answer:
<u> Neuromuscular Junction -</u> It is a chemical synapse formed by the contact between a motor neuron and a muscle fiber.
<u>Function- </u>As the motor neuron are <em>able to transmit the required signals</em> to the muscle fiber, which causes the muscle contraction.
Explanation:
<u>Steps in neuromuscular transmission:</u>
- calcium entry into the presynaptic terminus.
- diffusion of Ach across cleft.
- combination of Ach with post-synaptic receptors and Ach breakdown via esterase.
- opening of Na + /K + channels (cation channels).
- postsynaptic membrane depolarization (EPP).
I believe, from a population that is uniformly distributed through its habitat a biologist can infer that it has reached it's carrying capacity. Population distribution describes how the individuals are distributed, or spread through out their habitat. Population size and population measure are important measures of the population. When the population is uniformly distributed, it means that they are evenly spaced over the area they occupy, thus the individuals compete for a scarce environmental resources, such as water in a desert.
Answer:
The results indicate that two independently assorting genes are involved (modified 9:3:3:1 ratio), with white blocking the expression of color by the other gene. The ratio of white : color pups is 3:1, indicating that the F.1 is heterogeneous (W/w). Among colored dogs, the ratio is 3 black : 1 brown, indicating that black is dominant to brown, and the F.1 is heterogeneous (B/b). The original brown dog is w/w ; b/b, and the original white dog is W/W ; B/B. The F.1 progeny are W/w ; B/b, and the F.2 progeny are: 12: 3: 1.

The Coriolis Effect works at right angles to the direction of the air flow.
To make sure I double checked every other option.
