Answer:
scavengers
Explanation:
these are the animals that feed on carrion, dead plants,or refuse.
Answer:
Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;
Presence of Exoskeleton.
The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.
Varied habitats.
Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.
Bilateral Symmetry.
Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.
Jointed Legs.
Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.
Short generation time.
Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.
Reproduction strategy.
Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.
Segmented body.
Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.
The tetanic contraction of muscles help to lift objects heavier than our body weight by generating force, overcoming resistance.
<h3>What is muscle?</h3>
Muscle is defined as group of tissue combined together in order to form muscles and muscles are the structure maker of the body it means it provide proper structure to the body.
Muscle contraction has been defined as an action potential that travels along with the nerves to the muscle. The beginning of the muscle contraction occurs with signal generated from the nervous system.There are mainly two types of muscle contraction and the situation occur when a muscle contracts and the change in size takes place.
Therefore, The tetanic contraction of muscles help to lift objects heavier than our body weight by generating force, overcoming resistance.

Answer: B. reproducing
Explanation:
Reproducing is the characteristic which contributes to the production and generation of new cells in the body from the pre-existing cells through cell division and cell differentiation. This process helps in replacement of old and damaged cells of the body.
According to the given situation, the human skin heals as the skin cells performs the process of reproduction in which the new cells are formed from the pre-existing cells to replace the dead and damaged cells of the region of cut.
