Ecdysis
Ecdysis is the name of the process in which an arthropod sheds its exoskeleton and forms a new one.
Ecdysis is the process in which an arthropod or an insect shed its outer cuticle (exoskeleton), and forms a new one. Ecdysis is an essential process in the growth and development of organisms. In arthropds, this process takes place after various steps that are caused by a hormone (ecdysone) that is secreted from glands behind the brain. Organisms utilize high amount of energy while forming a new cuticle, and the old cuticle that is shed in this process is known as exuviae.

number two is F, nucleous
<span>A preload (stretching) is greater in cardiac muscle fibers before contraction increases its contraction force. This preload is compared to the stretching of an elastic band because the more stretched that band, the more strongly it will return to its resting length. Within certain limits, the more the heart fills with blood during diastole, the greater the contraction force it will exert during diastole. The preload is proportional to the end-diastolic volume. Normally, the higher the end-diastolic volume, the greater the force that the heart will develop in the next contraction.</span>
