Answer:
The environment usually refers to all the biotic and the abiotic components that are surrounding us. This environment undergoes changes depending upon various factors which can be natural and/or due to the anthropogenic activities.
When there occur rapid environmental changes, then it directly affects the lives of species, in different ways, such as-
- Those species that are comparatively weaker in adapting according to the environmental changes that occur, will not be able to cope up with the new environment. They may become extinct.
- Some variety of species will be able to adapt to the new environment because of their easily adapting capabilities.
- The traits that will be developed within the species in the new environment will be more successful in terms of reproduction.
- The previously existed traits may have a harmful impact in the newly formed environment.
Answer:
1. Chloroplast
2. cellular respiration
3. ATP
4. C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy
Explanation:
This question is describing the processes of photosynthesis and cellular respiration. Photosynthesis occurs in the CHLOROPLAST, which is responsible for the conversion of solar energy (from sun) into chemical energy (in glucose). The general photosynthetic reaction is:
6CO2(g) + 6H2O(l) + energy → C6H12O6(s) + O2(g)
Contrarily, the process of cellular respiration occurs in the MITOCHONDRIA. Cellular respiration involves the breaking down of food molecules to synthesize ATP (energy) for use during biochemical reactions. The general chemical reaction is as follows:
C6H1206(s) + 02(g) → CO2(g) + 6H20(I) + energy
Answer:
C. Disruptive Selection
Explanation:
Disruptive selection occurs when two extremes of continuous variation are favored more than intermediate traits.
The extremes of continuous variation exhibited in this species of snail is the color of their shell which allows them to blend with the background of their habitat.
The shady forest of the habitat makes the dark-shelled individuals to be better hidden from bird predators, while the light-shelled individuals are better hidden in well-lit brushy edge areas. This disruptive coloration exhibited by both individuals makes both individuals of this species of snail less vulnerable to predation.
Both individuals of this species both extremities would naturally survive in this habitat as snails with intermediate extremities would be highly preyed on since there is no area of intermediate brightness in the habitat to make them invisible to predators
The correct option is A.
The DNA from one specie differ from the DNA of another specie on the basis of their base ratio. The base ratio refers to the percentage of purine to pyrimidine in a DNA molecule. The base ratio is the one that is responsible for the variability that is observed in chromosomes from different species.
Answer:
trophic level
Explanation:
Each step of the food chain in the energy pyramid is called a trophic level.
