The blod of human spread whole over the cell before it entering two times on the heart
Answer:
1} Double circulation is a process during which blood passes twice through the heart during one complete cycle.
2}The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
3}
{a} An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
{b} Secondary Consumer Definition. Secondary consumers are organisms that eat primary consumers for energy. Primary consumers are always herbivores, or organisms that only eat autotrophic plants. However, secondary consumers can either be carnivores or omnivores.
4}Abiotic Components of Ecosystems. An abiotic factor is any non-living factor that is used or present in an ecosystem. Common abiotic factors include sunlight, oxygen, nitrogen, climate, temperature, pH levels, and water.
Examples of abiotic parts of the ecosystem are:
Water.
Climate.
Sunlight.
Minerals.
Available space.
Temperature.
