Hello.
Darwin concluded a couple things after finding fossails.
1. He claimed the ocean put animals on the mountions.
2. Sea rocks raised the mountions.
3. Sea levals were high and the animals that died are still on the mountion.
Have a nice day
<span>through the urethra to the postrate
Sperm at that point goes through the deferent channel through up the spermatic rope into the pelvic depression, over the urethra to the prostate . Here, the vas deferens joins with the fundamental vesicle to shape the ejaculatory channel, which goes through the prostate and exhausts into the urethra. At the point when discharge happens, muscle action impel the sperm forward.</span>
Answer:
C: Lipid A
Explanation:
Lipid A is a component of the endotoxin (also called the lipopolysaccharide) present in Gram-negative bacteria. The LPS has 3 component namely;
- the O-antigen: they are antigenic determinants and are the outer carbohydrate chains
- the core polysaccharide: forms the centre core of the LPS
- The Lipid A: forms the innermost part of the LPS and triggers acute inflammatory responses (e.g endotoxic shock) when released.
Upon detection of an endotoxin which forms the component of the outer membrane of a Gram negative organism (in exception to the Gram-positive bacteria called <em>Listeria monocytogenes</em>), the innate immune defense system (e.g macrophages and T-helper cells) are alerted to initiate elimination strategies towards the invading organism. Lipid A binds to the CD14/MD2 receptor on macrophages and monocytes which activates the nuclear factor kappa- light chain enhancer (NF-κβ). The activation of NF-κβ protein triggers the production of inflammatory cytokines which includes Interleukin-1 (IL-1), IL-12, IL-18 as well as the Tumor necrosis factor- alpha (TNF-α).
Inflammatory responses are as a result of the release of these cytokines which sometimes leads to shock and death of the host
I think it is Forrest fires. hope this helps <span />
Unlike a mixture, a compound has a chemical formula that is always same.
