Answer:
un sapo puede cambiar su sexo a hembra para que puedan reproducirse incluso si no hay ninguna hembra.
Explanation:
Answer:
C. Sex cells
Explanation:
The process shown in the figures is Mitosis, which is the division of cells that end in 2 identical daughter cells. Sex cells, however, do not go through mitosis as their offspring are genetically different; they go through a process called meiosis. The other cells listed are all somatic and therefore go through mitosis, so C must be correct.
Physical Structures - They have small gils to breathe under water.
Coloring - Dark and Light Brown Spots with Tan body
Habitat - cold streams, lakes, pond, under rocks, and logs.
Scientific Name - <span>Dicamptodon aterrimus</span>
Answer: mechanical weathering
Explanation:
Weathering is the breaking down of rocks into small fragments or pieces by agent such as animals,water, wind. Erosion helps in the transport of this materials from its region to another.
Mechanical weathering is also known as physical weathering, it causes rocks to crumble as a results of disaggregation of rocks which could results from cracks, freeze thawing.
Water is an important agent of mechanical weathering, in either liquid or solid form.
Liquid water can seep into cracks and crevices in rock as in the case of Lurray Caverns in Virginia,and rock fragments will be eroded this materials accumulation of this leads to a new formation of calcite. If temperatures drop low enough, the water will freeze creating an expansion in the rock that could results in a crack or fragments of rocks falling off.
The process by which two species evolve in response to changes in each other over time is called C. coevolution.
