Answer:
These include the carbon oxides, hydrocarbons, and halocarbons (molecules with carbon bonded to F, Cl, Br, or I).
Explanation:
Answer:
1. T cells
2. B cells
Explanation:
With increased age, people become more prone to all infections and produce fewer responses for vaccines. This is due to the lowered levels of function of immune systems against the infections.
With increased age, thymus atrophy and/or hyposecretion of hormones from thymus gland result in reduced activity of T cells against infections. Less number of T cells respond to infections.
The reduced T cell production also makes the B cells less responsive. Reduced responses of B cells towards infection results in slower immune response as antibody levels do not rise quickly.
For this item, we assume that the gas behaves ideally such that it follows the ideal gas law and the ideal gas equation is applicable.
PV = nRT
where P is pressure, V is volume, n is number of moles, R is universal gas constant, and T is temperature. When the right-hand side of the equation is constant, there exist a relationship that,
P₁V₁ = P₂V₂
Substituting the given,
(0.410 atm)(32 L) = (P₂)(28 L)
The value of P₂ is equal to 0.4686 atm.
Answer:
d. Ribosome
f. Cell wall
Explanation:
In humans 80s type of ribosome is present and in bacteria 70s type of ribosome is present. Human cells do not have cell wall while bacterial cells have peptidoglycan cell wall. These differences can be targeted by the potential antibacterial agents.
For example, tetracycline antibiotic inhibits the binding of important molecules to bacterial ribosome which ultimately inhibits the protein synthesis in bacteria. Vancomycin antibiotic on other hand inhibits the cell wall formation in bacteria by inhibiting peptidoglycan synthesis.
Answer:
Glucose and glycogen are both stored in the liver, but glucose is used first for energy, then glycogen.
