Option b is correct..
Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
charcoal or water. water would considered an organic fuel because for one its organic and for two it is used to hydrate and to replenish life. if water was not here, everything would die.
15×3=45 because p=m.v so simply finish this question.
Answer:
B. preservation of advantageous genetic mutations
Explanation:
The process of natural selection involves the preservation of advantageous genetic mutation in a given population.
Natural selection is one of the key factors that ensures the evolution of organisms.
- Desired traits that are able to survive adverse conditions like disease, food shortage, natural disasters are favored by the process of natural selection.
- Traits that also undergo advantageous genetic mutation in order to get a competitive advantage is also accrued to natural selection.
<h3><u>Answer;</u></h3>
D) frequently, and sometimes rapidly
<h3><u>Explanation;</u></h3>
- The hypothesis that the Grants have been testing was about the natural selection shaping the beaks of different bird populations.
- <em><u>The Grants documented that natural selection takes place in the wild finch population frequently, and sometimes rapidly.
</u></em>
- The Grants' work showed that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
