You didnt post a picture of the organism you cant get a answer without it
Answer:
Genetic variation among plant populations often occurs along different climatic gradients, such as temperature and precipitation gradients.
Environmental factors are often responsible for the patterns of genetic structure observed at small spatial scales (Sacks, Brown, & Ernest, 2004).
Answer: determining the structure of sediments and basement rock
Seismic profiling is the process of analyses of surface and subsurface characteristics of earth with respect to the seismic activities like volcanic eruption, earthquakes. These seismic activities can be measurement depending upon the type of sediments and rocks deposits at the base of the earth. It can also include striagraphy which gives idea about different layers of rocks deposition with seismic activity.
The information given about taste and the tongue is explained below.
<h3>
How to explain the tongue?</h3>
The food enters the mouth passing the <u>TOT (tip) </u>of the tongue. It is moved around by the motion of the tongue and teeth as the food is chewed. Its movement is facilitated by the<u> taste buds</u> on the tongue which are jagged, aiding in their ability to move food.
<u>Fungiform papillae </u>on the <u>side</u> of the tongue and<u> filiform papillae</u> located on the dorsal surface of the tongue come in contact with the <u>tastant</u>.
Both types of papillae have<u> taste buds</u> that have receptors for individual tastes -sweet, sour, salty umami (savory), and bitter. Once a tastant is bound to the receptor it creates a signal that travels through one of the three carnival nerves depending on the location of the taste buds. For taste buds located on the front of the tongue, the signal travels through the <u>facial nerve</u>.
For taste buds located in the middle of the back of the tongue, signals travel through the <u>glossopharyngeal nerve</u>. The signals travel to the nucleus of the solitary tract of the brainstem, where they are relayed to the thalamus for higher processing.

Answer:
Evolution - It occurs due to the continuous variations and diversifications coming from the past generations
Natural Selection - In this process, the individuals are naturally selected by the environment that fits in perfectly!
Evolution - Driven by natural selection
Natural Selection- Driven by new characters that are the results of mutations
Evolution - Duration of Action Acquires millions of years
Natural Selection - Can be done in a short duration
Evolution - Example ;- Darwin’s finches, bright-colored peacocks, Mexican cavefish, etc.
Natural Selection -Example ;- Tree-frogs are mostly eaten by snakes, giraffes with short and long necks, etc.
