Answer:
Lymph nodes swell to protect us from illness if they do not swell non fatal illnesses could spell out death
Explanation:
Explanation:
Receptors = Sensory neurons
Relay = Relay neurons
Effectors = Motor neurons
Cell bodies of sensory neurons are only found in the root ganglion. (F)
Cell bodies of relay neurons are only found is the grey matter of the spinal cord. (G)
Cell bodies of motor neurons are also found at G.
Hence the answer is Option D.
Answer:
The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.
Explanation:
In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied. This means making minimal adjustments in order to better observe the microscopic image.
After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.
The other options are not correct because:
<em> A. </em><em><u>Eyepiece</u></em><em> is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.</em>
<em> C. </em><em><u>Coarse Adjustment </u></em><em>is the rough magnification, used for the initial approximation of the image.</em>
<em> D. </em><em><u>Objective lens</u></em><em> enlarges and defines the image of the sample on the slide.</em>
The answer is mutation
of genes. The mutations were beneficial and gave the individuals of the population
advantage and hence increased their survival. The classic features of birds
evolved one by one and gave birds advantage over their dinosaurs counterparts, especially the feature of small size.
<h2>Answer:</h2>
The one condition that must be met for a population to be in genetic equilibrium:
A Large Breeding Population.
<h3>Explanation:</h3>
- A large breeding population helps to ensure that chance alone does not disrupt genetic equilibrium.
- In a small population, only a few copies of a certain allele may exist.
- If for some chance reason the organisms with that allele do not reproduce successfully, the allelic frequency will change.
