Well, if anthropods could tell the difference between relatively weak clams and tougher weak clams, they could better seek out the weaker clams. That way the anthropods would have a higher rate/chance of survival, because they would be able to locate food easier. There would be less anthropod deaths, which is why they would choose the weaker clams. In the end, anthropods would demonstrate excellent fitness in their environment and most likely thrive because of their ability to distinguish weaker clams from tougher ones.
I hope this helped you :)
Answer:
Salmonella are made of Flagella which prevent it from being phagocytosed.
Flagella is a long filamentous organelle responsible for bacterial motility. falgella are present exteranlly in all three dimensionally in salmonella and it helps salmonella to swim in liquid conditions and rotates the flagella on firm surfaces.
Flagella is known as PAMPs (pathogenic molecular patterns) in salmonella which is used by the host to identify bacteria and activate the immune system of the bacteria.
Hence, rotating or motility and immune function of flagella in salmonella prevent it from being phagocytosed.
<span>During the ALARM STAGE of the general adaptation syndrome, catecholamines are released by the adrenal medulla, intense arousal occurs, and the body mobilizes internal physical resources to meet the demands of the stress-producing event.
This gives the body a burst of energy to flee from the scene that causes the stress to prevent the further damage that might happen to the body. Kind of similar when you accidentally touch the flame on a candle, your body automatically undergoes alarm stage and signals your brain to move your hand away from the heat that caused you pain.</span>
Answer:
(a) (Glu)zo or(Phe-Met)3 at pH 7.0
O (Glu)zo ✔
O (Phe-Met)s ❌
(b) (Gly) zo or (Lys-Ala)3 at pH 7.0:
O (Gly12) ❌
O (Lys-Ala)✔
(c) (Ala-Asp-Gly)s or (Asn-Ser-His)s at pH 3.0:
O (Asn-Ser-His)s ✔
O (Ala-Asp-Gly)s ❌
(d) (Ala-Ser-Gly)s or (Asn-Ser-His)s at pH 6.0:
O(Ala-Ser-Gly)s ❌
O (Asn-Ser-Hish)s ✔
Explanation:
Polypeptides that has polar or charged side chains are more soluble than polypeptides with nonpolar side chains.
(a) At ph 7.0
(Glu)20 is negatively charged at pH 7 and more soluble
(Phe-Met)3 is observed to be less polar and less soluble
(b)At ph 7.0
(Lys-Ala)3 is positively charged (polar) and more soluble
(Gly)20 is uncharged as only the amino- and carboxyl-terminal groups are charged as its less polar and less soluble too.
(c) At pH 6.0
(Asn-Ser-His)5 has polar Asn side chains and partially protonated His side chains and it's more soluble unlike the (Ala-Asp-Gly)s at that pH.
(d) At pH 3.0
(Asn-Ser-His)s as partially protonated carboxylate groups of Asp residues and it is also neutral but the imidazole groups of His residues are fully protonated and positively charged. Hence it's more soluble than the (Ala-Ser-Gly)s at that particular pH.
