Answer:
The correct option is d. Metabolic specificity
.
Explanation:
The specificity principle says that we must train the physical qualities (physiological elements involved) in the concrete conditions that the competition demands. Accordingly, the impact on muscles and metabolic pathways not used directly during exercise is very small. Metabolic specificity is a principle of adaptation and it applies to the energy systems mobilized during the exercise. The muscle mass involved and the overall intensity of the exercise will dictate whether the responses to training will be limited to adaptations at the muscular level or if adaptations will occur at the cardiovascular level. Continuous aerobic training of submaximal intensity is reflected in the increase in the activity of oxidative metabolism enzymes. The running speed of a marathon is regulated by aerobic metabolism in the recruited muscle fibers and by the economic conversion of this energy into speed. Increasing the distance and time of her races progressively allows the endurance athlete to exercise at a high intensity for significantly longer periods of time.
The pen would contain Insulin as people with diabetic problems do not have enough insulin in their body to help them break down the sugar
Answer:
The dry-out material contains spores of anthrax-causing bacteria
Explanation:
<em>Anthrax is a disease caused by a bacteria known as Bacillus anthracis. Susceptible animals get infected by anthrax when the spore of the bacteria gets into their bodies, become activated, multiply and produce toxins.</em>
The spore serves primarily as a propagating structure and also as an agent for transmitting infections. It can be transmitted by air, water, food or any other means. Bacterial spores usually have the capability to tolerate harsh environmental conditions and only become inactivated when conditions are favourable.
The dry granular powdery material constituent of the letters received by the U.S. senators must have been spores of <em>Bacillus anthrasis</em>
Answer:
B. Organisms in each ecological system have evolved in that system and have adaptations suited for that environment.
Explanation:
According to natural selection theory, organisms need to continuously adapt and evolve within an environment or risk being wiped away from that environment.
Organisms that are not able to adapt to an environment are gradually replaced by those that have the capability to adapt and survive in that environment.
Those that are able to survive go ahead to reproduce and give rise to offspring with inherent ability to survive while those that cannot survive die off.
The correct option is B.
