The electron transport chain depends on the Krebs cycle to produce NADH and FADH2. These are the starting materials for the chain to be able to make ATP. No the first aerobic part of cellular respiration is the electron transport chain.
Answer: Stratum Corneum
Epidermis. The epidermis is the thin outer layer of the skin. It consists of 3 types of cells: Squamous cells. The outermost layer is continuously shed is called the stratum corneum
Explanation:
stratum corneum
The epidermis has no blood supply and depends on diffusion from the dermal cells for its metabolic needs. The dead-cell layer of the stratum corneum provides the protection from water loss that allows vertebrates to dwell on land

Sympathetic nervous system
The neuron, a cell that composes the nervous system. For example a brain, an organ composed of thousands of neural fibers and glial cells that performs many important organismic functions. </span>
<span>Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions.<span>

Answer:
The statement is true
Explanation:
Hematopoietic stem cells give rise to myeloid progenitor and lymphoid progenitor and these two progenitors give rise to many immune cells. Dendritic cells are produced by both the progenitors and macrophages are produced by myeloid progenitor.
Both macrophages and dendritic cells are phagocytes. In phagocytosis, the foreing particles are injected by these phagocytes and they are destryoyed by the action of digestive enzymes present in these phagocytic cells.
Macrophages are present in tissue and if they are present in blood they are called monocytes. Therefore the statement is true.
He took swabs of one pea plant and put it on others to help them reproduce.
