The helper T cell is active when....
It has engulfed a pathogen
It has learned the shape of the antigen
It has made the MHC protein
T cells undergo a clonal expansion and differentiation followed by a contraction phase, once the pathogen has been cleared.
How does the T cell respond to a pathogen?Recent in vitro and in vivo evidence supports an antigen-pre-senting role for T cells. Human T cells exhibit major histocompatibility complex (MHC) class II antigens and adhesion molecules that are typical of antigen-presenting cells (APCs).
Controlling the populations of effector, memory, and naive T lymphocytes depends on cell survival and death. The presence of MHC proteins in the antigen-presenting cell is necessary for the identification process because they bind to these fragments, transport them to the cell surface, and present them to the T cells there together with a co-stimulatory signal.
Due to their dual specificity, T cells can distinguish between peptide antigens presented by self-MHC I or MHC II molecules and those presented by other MHC molecules.

A. Specific heat values for solids will never vary for different ranges of temperature.
B. The specific heat of a gas can be measured at constant pressure.
C. Specific heat values for liquids will never vary for different ranges of temperature.
D. The specific heat of a gas can be measured at constant volume only.
When talking about specific heat, it is correct to say that a gas's specific heat may be determined at constant pressure. The correct option is B.
The amount of heat needed to increase a substance's temperature by 1 degree Celsius or Kelvin is known as its specific heat. The specific heat of a gas can be measured at constant pressure.
The specific heat for gases can be calculated at either constant volume or constant pressure. The heat capacity at constant pressure (Cp) and heat capacity at constant volume (Cv) are the terms used to describe the specific heat when measured at constant pressure and constant volume, respectively. For the majority of gases, Cp has a larger value than Cv.

With the use of site-directed mutagenesis, hemoglobin has been prepared in which the proximal histidine residues in both alpha and the beta subunits have been replaced by glycine. The imidazole ring from the histidine residue can be replaced by adding free imidazole in solution. Would you expect this modified Hb with free imidazole to exhibit oxygen binding? Why or why not?
Answer:
The modified hemoglobin with free imidazole cannot be expected to show cooperativity in oxygen binding. The movement of iron ion takes place up in the plane of heme when binding of one subunit of hemoglobin takes place with oxygen. One of the iron's and oxygen's axial ligands comprise the proximal histidine's imidazole ring.
With the movement of iron into the hemoglobin ring, the pulling of proximal histidine takes place along with it. Therefore, when binding of oxygen takes place with one subunit, a modification also takes place in the intersubunit associations, this also comprises displacement of the alpha helix. This phenomenon plays an essential role in modifying the hemoglobin's tensed state to the relaxed state. The withdrawal or mutation of the imidazole ring from the histidine residue does not further permit the cooperative binding as it is not associated physically with the alpha-helix.

What is the difference between blue green and fungi?
Blue-green algae are photosynthetic prokaryotes, while fungi are eukaryotes that obtain nutrition through absorption.
Blue-green algae and fungi are both organisms, but they belong to different domains and have distinct characteristics. Blue-green algae, also known as cyanobacteria, are classified under the domain Bacteria, while fungi belong to the domain Eukarya.
Blue-green algae are prokaryotic organisms, lacking a true nucleus and membrane-bound organelles. They obtain energy through photosynthesis and are capable of converting sunlight into chemical energy. They typically inhabit aquatic environments, such as lakes, ponds, and oceans, and some species can fix atmospheric nitrogen.
On the other hand, fungi are eukaryotic organisms with a distinct nucleus and membrane-bound organelles. They obtain nutrition by absorbing organic matter from their surroundings. Fungi play crucial roles in decomposition and nutrient cycling in ecosystems. They can be found in various habitats, including soil, plants, and even as symbiotic partners with other organisms, such as in mycorrhizal associations.
In summary, the primary differences between blue-green algae and fungi lie in their cellular structure, mode of nutrition, and classification. While blue-green algae are photosynthetic prokaryotes, fungi are eukaryotes that obtain nutrition through absorption. Understanding these distinctions helps in appreciating the diversity and ecological significance of these two groups of organisms.
