Since each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber.
Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens
Mechanism :
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers.

Which statement best explains why cooperation between countries is necessary to prevent a tragedy of the commons?
Since there are so many common areas, sharing between countries should be easier.
If one country overuses a common resource, it depletes the common resource for all.
Common areas are divided among only a few countries, and little access is given to the rest.
Too many countries have access to common areas, and this prevents them from sharing.
The statement which best explains why cooperation between countries is necessary to prevent a tragedy of the commons is that If one country overuses a common resource, it depletes the common resource for all and is denoted as option B.
What is Tragedy of the commons?This is referred to as a situation in which the resources are available to the people and they are overused due to the ease of access to them.
Cooperation between countries will help to curb a country overusing a common resource which will lead to the depletion of the common resource for all.

A car with a mass of 1,324 kilograms, traveling at a speed of 20 meters/second, crashes into a wall and stops. What is the kinetic energy after this perfectly inelastic collision?
The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
How to calculate kinetic energy?The kinetic energy of a moving car can be calculated using the following formula:
K.E = ½ × m × v²
Where;
K.E = kinetic energym = mass v = velocityK.E = ½ × 1324 × 20²
K.E = 264800J

write detail note on malaria 2 study
A detailed note on the malaria is discussed below:
What is malaria?A parasite that frequently infects a particular species of mosquito that feeds on people can result in the serious and occasionally fatal disease known as malaria. Malaria often causes severe disease, including high fevers, shivering chills, and flu-like symptoms. Humans can contract four different types of malaria parasites: Falciparum Plasmodium, P.
Female Anopheles mosquitoes carrying the Plasmodium parasite bite people to feed their own eggs, which is how the parasite is propagated. An infected mosquito injects sporozoites, or early stages of the parasite, into the host's bloodstream while it consumes its prey (often between twilight and sunrise). The sporozoites are transported by the blood to the liver, where they develop into schizonts, which are a type of parasite. Each schizont multiplies into thousands of merozoites throughout the course of the following one to two weeks. The merozoites escape the liver and re-enter the bloodstream where they assault red blood cells, continue to grow and divide, and eventually kill the blood cells.
