Answer:
The answer is B- no muscle tension could be generated
Explanation:
During contraction cross bridges are formed by the myosin thick filaments grabbing on to the actin thin filaments. . The overlap of the thick and thin filaments allows myosin to bind to actin. As more bridges are formed, more myosin will pull on actin and more tension will be produced. Muscle tension is a condition in which the body remains semi-contracted for a longer time, it is caused when muscles contracts and do not release.
However, if the muscles are stretched to a point where the thick and thin filaments no longer overlap there will be no muscle tension generated.
Foxes eat a variety of animals, which includes caterpillars. On the contrary, most caterpillars eat only plants. In any ecosystem, you always have a larger number of plants than the number of animals which eat plants, and you have an even smaller number of animals which eat other animals. That is related to the flow of energy in the ecosystem:
1) The sun provides solar energy and plants use part of it for photosyntesis. Later, that energy will be stored by the plant as chemical energy.
2) Herbivore animals eat some of the plants, in order to use their chemical energy. Animals can never eat all plants because that would lead to extinction. Besides, part of the chemical energy of the plants they have eaten is wasted because it converts into heat energy.
3) Carnivore animals eat herbivore animals. Same conclusion, they can never eat all herbivore animals and they cannot use all their energy. If they are ominvore, they are sort of sharing the plants with herbivores, so herbivores can eat less plants.
Malnutrition reduces the population, so less food leads to smaller population.
Answer:
c
are animals typically characterized by their anus forming before their mouth during embryonic development.
Answer:
Mutation that reduces the affinity of the lactose repressor for lactose.
Explanation:
The operon model is operated in prokaryotes for the regulation of gene expression. The lac operon is active for the metabolism of the lactose and the genes that are associated with the metabolism.
The repressor molecule regulates the expression of the Lac operon. This repressor molecule binds with the DNA sequence tightly and blocks the transcription. The mutation that results in the decrease ability or affinity for the lactose might results in the continuous expression of the gene.
Thus, the correct answer is option (d).
