Answer:
Angiosperm
Explanation:
The mitochondria of flowering Angiosperm plant are the largest. The size of these mitochondria varies from 1.86 million bp to 2.4 million bp. It is also the most complex one as it carries large number of repeating units which allows multiple permutations for recombination. This allows generation of mitochondria of varying sizes with in the same species.
It is least gene dense as the inter regions are highly expanded. One of the most distinguishing feature of these mitochondria's are that they contain polypeptides. These polypeptides are basically non functional but have potential to evolve into functional one.
Tetanus
Tetanus is an acute bacterial
infection caused by the Clostridium tetani bacterium. It is
characterized by muscle spasms. The bacteria enter the body through a deep cut
or wound. The early symptoms of this infection include diarrhea, fever, and
headache. Other symptoms include sweating and rapid heartbeat.
Answer:
Innate immune response.
Explanation:
TLR also called toll-like receptors play crucial role in innate immune response. They are single spanning proteins and are present on dendritic cells and macrophages.
The pathogen when enters the body via skin or epithelial of mucosal membrane, they are recognized by TLR that further activates the immune response.
TRUE. The resource is always able to be reproduced- A tree can grow even after another tree is cut down.
