The correct answer is option C, that is, physical weathering.
The weathering resulting due to the influences of changing temperatures on a rock, making the rock to split apart is known as physical weathering. There are two main kinds of physical weathering, that is, exfoliation and freeze-thaw.
Physical weathering takes place mainly in the locations, where few plants grow and little formation of soil occurs, like hot deserts and mountain regions. It takes place either via repeated freezing and melting of water or via contraction and expansion of the rocks surface layer, which is baked by the sun.
Answer:
- Autotrophs are usually defined as those that can prepare their own food by carrying out the process of photosynthesis, but heterotrophs cannot prepare their own food and are directly dependent on the autotrophs for food. Examples of autotrophs are plants and trees, and examples of heterotrophs are animals and human beings.
- Autotrophs are the lowest organisms in the trophic level, where they produce the food for the consumers (heterotrophs). On the other hand, the heterotrophs lie above the autotrophs and when they consume their food, they obtain only 10% of the energy, and the remaining energy is released into the environment.
- Autotrophs can make organic substances by the use of inorganic molecules, but heterotrophs cannot make these substances. They are only dependent on the molecules prepared by these autotrophs.
Thus, these are three of the facts regarding autotrophs and heterotrophs existing on earth that are true.
The answer is the last one
- carrying genetic material
Answer:
c. it leads to a redistribution of alleles
Explanation:
The gene flow can be defined as the movement of genetic material from one population to another within the same species. This movement may be associated 1-with the migration of individuals and subsequent reproduction of these organisms in the new population or 2-with the movement of gametes (eg., pollen dispersal) among populations. In both cases, gene flow is known to alter the frequency of particular alleles between populations and consequently also modify the evolutionary patterns of these populations.
Answer: The name means many sugars, so polysaccharide meaning many sugars works for it.
