Answer:
The pericardium is the most outer layer of the heart. Main function to protect the heart from external forces/entry.
Entire muscles are encased in the epimysium. The perimysium, which is connected to the epimysium, separates groups of muscle fibres into fasciculi. Individual muscle fibres are encircled by a delicate network of connective tissue fibres, blood arteries, lymphatic vessels, and nerves called the endomysium.
The collagen fibres of tendons are made of endomysium, perimysium, and epimysium, and they serve as the tissue link between muscles and bones by indirect attachment. Intermittent perimysial junction plates serve as its connection to the perimysium.
The perimysium, which surrounds bundles of muscle fibres, the endomysium, which surrounds individual muscle fibres, and the epimysium, which surrounds the muscle, are the three scale levels at which connective tissue of the muscle may be identified.

Answer:
Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.
Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.
Fungi. Many skin diseases, such as ringworm and athlete's foot, are caused by fungi. Other types of fungi can infect your lungs or nervous system.
Parasites. Malaria is caused by a tiny parasite that is transmitted by a mosquito bite. Other parasites may be transmitted to humans from animal feces.
Explanation:
i write it with the explanation on when i answer it
When using the term 'life form' I assume you are speaking of animals, bacteria, etc. Scientists take years to find their desired conclusion because of how the environment tends to change quite frequently (Depending on where the creature lives). The earth is constantly revolving and rotating, which causes changes in the environment. These changes affect the animals behavior, eating habits, and overall chances of survival. A factor that must also be considered is that scientists have to examine these creatures in their natural habitat which can be an issue depending on where they live. For example, if I were to study the behavioral patterns of a Leopard, it would be extremely difficult to do so because the Leopards are specifically keen at camouflaging in their environment. That would make observing its behavioral patterns very frustrating and time consuming. In a way, mother nature is always against us.

Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP
