Answer:
Blood-brain barrier.
Explanation:
Blood brain barrier may be defined as the barrier between the blood capillaries and the component of the brain tissue. This blood brain barrier provide protection against the pathogens present in the blood.
The blood-brain barrier uses tight junctions that prevent the entry of microbes in the underlying tissue. The tight junctions allows only the entry of some selected particles and prevent the entry of other particles.
Thus, the correct option is (3).
Answer:
1.A tissue is a collection of similar cells that work together to perform a specific job.
An organ is a collection of different tissues that work together to perform a specific job. The function of a part of an organism is what it actually does (it's job)
2.The structure of the alveoli as a web of blood vessels surrounding an air sac allows blood cells take in oxygen and bring it into the lungs (organ)
Answer:
(1) roots, (2) stems, (3) leaves, and (4) flowers
Explanation:
Answer:
Decellularization is the process used in biomedical engineering to isolate the extracellular matrix (ECM) of a tissue from its inhabiting cells, leaving an ECM scaffold of the original tissue, which can be used in artificial organ and tissue regeneration. Organ and tissue transplantation treat a variety of medical problems, ranging from end organ failure to cosmetic surgery. One of the greatest limitations to organ transplantation derives from organ rejection caused by antibodies of the transplant recipient reacting to donor antigens on cell surfaces within the donor organ. Because of unfavorable immune responses, transplant patients suffer a lifetime taking immunosuppressing medication.
The process of apoptosis, I believe, is when the tadpole's tail is reduced in size during metamorphosis.
In most animal phyla, metamorphosis actually takes place in conjunction with morphological, ecological, and physiological changes.
Marine invertebrates' larva behaves as a drifting tiny creature in the ocean, expanding its habitat distribution to find the best location for its survival.
When muscle cells undergo apoptosis, which is the final stage of their metamorphosis, they are split into membrane-bound muscle fragments and consumed by macrophages.
As a tadpole becomes a frog, apoptosis occurs. The cells in its tail are induced and it will be lost.
