Answer:
A was the answer to mine but u didn't post your diagram so I don't know
Explanation:
Answer:
The cranial nerves are the set of 12 pairs of nerves which are originated from the brain. As they are responsible for some of the essential functions , such as vision, smell, and balance of the human body structure.
<u>The 12 pairs of the cranial nerves are as as under:</u>
- The olfactory nerve
- The optic nerve
- The oculomotor nerve
- The trochlear nerve
- The trigeminal nerve
- The abducens nerve
- The facial nerve
- The vestibulocochlear nerve
- The glossopharyngeal nerve
- The vagus nerve
- The spinal accessory
- The hypoglossal nerve,
- It is very hard for the students to remember all the names of the cranial nerves as we can just recall them by memorizing the device-<em>Old Opie Occasionally Tries Trigonometry And Feels Very Gloomy, Vague And Hypoactive.</em>
Explanation:
The optic chasma originates as one of the cranial nerves, as it serves for the function of vision sense in human body. The nerves are responsible for carrying the set of information and data from the retina of the eye to the brain. As the communication between the two regions or part of the body, as they hold the capacity to carry the charges or information from the retina of the eye towards the brain.
energy enters an ecosystem through photosynthesis. By feeding on plants and on one another, animals play an important role in the movement of the matter/energy though. they also influence the quantity of plant and biomass present. so the anwser is D, secondary consumers to tertiary consumers
Directional selection favors one of the extreme phenotypes. Option B). Fewer plants with thin seed coats will be able to germinate, leading to a higher proportion of plants that produce seeds with thick seed coats.
<h3>What is directional selection?</h3>
Directional selection increases in the proportion of individuals with an extreme phenotypic trait.
There must be a selective pressure or environmental pressure acting on populations to lead the species to increase the number of individuals expressing that extreme phenotype.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example the environmental pressure is drought during several years.
Drought periods decreases the fitness of plants that produce thin seed coats because they dehydrate before germinating.
Originally the population expressed both types of seeds. But after the drought pressure, only plants that produce seeds with thicker coats got to survive and reproduce.
The correct option is B). Fewer plants with thin seed coats will be able to germinate, leading to a higher proportion of plants that produce seeds with thick seed coats.
