Answer:
Contracting muscle fibers do not always shorten.
Explanation:
Skeletal muscle fibers may be defined as the fiber that contain the single muscle cell that is cylindrical in nature. The connective tissue present in muscle is epimysium.
The contraction of the skeletal muscle fiber helps in the movement of the body. The contraction of the muscle fiber do not means that the muscle fiber gets shorten. The thick and thin filaments remains in their original length and the sarcomere shortens only.
Thus, the correct answer is option (C).
Answer:
The best answer to this question, given the research found from a study done by the University of Queensland, on 2014, and which expanded along 40 years of collected data on ectotherms, would be: Ectotherms will have to expend more energy to cool their body temperatures.
Explanation:
Ectotherms is the term used to describe animals whose regulation of body temperature depends mostly on the external environment and the conditions of it. This group represents around 90% of animals and their development and wellbeing depends on the climate, especially temperature, conditions, on an environment. One positive side to ectotherms is that they have an easy adaptation rate to changing climate. However, according to the study carried out by the University of Queensland, ans which was published in 2014, ectotherms are finding it a challenge to cope with the rate of change in climate temperatures duw to global warming. This rise in temperatures is leading animals to have to expend much more energy with the rise of temperatures and thus, there has been a drop in animal reproduction and generation of new species.
Answer:
The term 'colo' means large intestine and the term 'scopy' means observing things with an instrument. Hence, the term coloscopy would mean the endoscopic observation of the large intestine. An CCD camera or a fibre-optic camera are the instruments that are used for this procedure. Coloscopy is generally termed as colonoscopy.
The method of colonoscopy is effective to diagnose a wide number of toxic diseases of the large intestine. Colon cancer can also be screened through this technique.
