Answer:
- Cell mediated immunity uses what type of WBC to attack and kill the infected cell? <u>T-cells</u>
- <u> Helper T </u>or <u>Killer T cells</u> are released that cause the cell to lyse or <u>undergo apoptosis.</u>
Explanation:
White blood cells or leukocytes are integral to cell-mediated immune function in the human body. T cells are produced in bone marrow, and mature in the thymus. They recognize antigens on virus-infected cells and target them for attack; antigens and receptors fit together to allow for identification.
- Helper T cells aid in activating other immune cells, along with eliminating cells infected by pathogens; they release cytokines
- Killer T cells produce special toxins (perforins and then cytotoxins) that lead to cell lysis and programmed cell death or apoptosis.
Photosynthesis process corresponding with flow of matter and energy within ecosystem is given below.
Explanation:
- Nothing matters without energy. Certain living bodies convert solar energy from the sun into synthetic energy by the process of Photosynthesis which is used to produce carbohydrate molecules.
- The energy collected in the bonds is used to hold these molecules and it is released when the organism breaks down food particles.
- This energy is then utilized to perform physical activities.
- Energy is not reclaimed in an ecosystem instead it is converted from one state of energy to the other.
