I want to know full answer about ecoregion vs. ecosystem.
Answer:
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point).

Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Secondly, ecoregion boundaries rarely form abrupt edges; rather, ecotones and mosaic habitats bound them. Thirdly, most ecoregions contain habitats that differ from their assigned biome. Biogeographic provinces may originate due to various barriers, including physical (plate tectonics, topographic highs), climatic (latitudinal variation, seasonal range) and ocean chemical related (salinity, oxygen levels).

Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA
Answer:
Total ATP molecules produced = 94 molecules of ATP
Explanation:
Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.
Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and FADH₂ and NADH molecules.
The overall yield of ATP from the various enzymatic steps is shown below:
Acyl-CoA dehydrodenase = 6 FADH₂
β-Hydroxyacyl-CoA dehydrogenase = 6 NADH
Isocitrate dehydrogenase = 7 NADH
α-Ketoglutarate dehydrogenase = 7 NADH
Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)
Succinate dehydrogenase = 7 FADH₂
Malate dehydrogenase = 7 NADH
Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,
Total ATP from FADH₂ molecules = 13 * 1.5 = 19.5
Total NADH molecules = 27 * 2.5 = 67.5
Total ATP molecules produced = 19.5 + 67.5 + 7 = 94
Total ATP molecules produced = 94 molecules of ATP

Following antigenic stimulation, phosphorylation of _________ relieves inhibition of the transcription factor
Answer: zap70, ITAM.
Explanation:
An antigen is any substance that is capable of stimulating an immune response by activating lymphocytes, which are the body’s infection-fighting white blood cells. Examples of antigens could be proteins that are part of bacteria or viruses or components of serum and red blood cells from other individuals, all of them are foreign antigens originated outside the body. However, there can also be autoantigens (which are self-antigens), originated within the body. In normal conditions, the body is able to distinguish self from nonself. And the antigens that represent a danger induces an immune response by stimulating the lymphocytes to produce antibody or to attack the antigen directly. This is called an antigenic stimulation of the immune system.
ZAP-70 (Zeta-chain-associated protein kinase 70) is a protein that is part of the T cell receptor, thereby it plays a critical role in T-cell signaling. When the TCR (receptor of T cells) is activated by the presentation of the specific antigen through the MHC, a protein called Lck acts to phosphorylate the intracellular CD3 chains and the ζ chains of the TCR complex, allowing the binding of the cytoplasmic tyrosine kinase, ZAP-70. Lck then phosphorylates and activates ZAP-70, which in turn phosphorylates another molecule in the signaling cascade called LAT (short for Linker of Activated T cells), a transmembrane protein that serves as an anchor site for several other proteins. The tyrosine phosphorylation cascade initiated by the Lck culminates in the intracellular mobilization of calcium ion (Ca2+) and the activation of important signaling cascades within the lymphocytes. These include the Ras-MEK-ERK pathway, which is based on activating certain transcription factors such as NFAT, NFκB and AP-1. These transcription factors regulate the production of of certain gene products, most notably cytokines such as interleukin-2 that promote the long-term proliferation and differentiation of activated lymphocytes.
The ITAM motifs (immunoreceptor tyrosine-based activation motif) are sequences of four amino acids present in the intracellular tails of certain proteins that serve as receptors within the immune system. Thus, some receptors such as the TCR have ITAM sequences that, when activated, trigger an intracellular reaction based on consecutive phosphorylations. Kinases are recruited for this purpose.
So, ZAP-70 is a protein tyrosine kinase with a role in T-cell receptor signal transduction. During T-cell activation, ZAP-70 binds to ITAM and becomes tyrosine phosphorylated. The binding of ZAP-70 to the phosphorylated ITAM is able to activate its kinase activity, and relieves the inhibition of the transcription factor which regulates genes that are involved in the immune reaction.

Explanation: Cytoskeleton is a microfilaments, intermediate filaments, and microtubules that provide support and movement for eukaryotic cytoplasm.
1. Prokaryotic cytoplasm lacks certain features of eukaryotic cytoplasm, such as cytoskeleton and cytoplasmic streaming.
2. The cytoskeleton provides support and shape to cell.
3. It help in transporting substances through cell.
4. It help in phagocytosis.
5. It help in cytoplasmic streaming that is movement of eukaryotic cytoplasm from one part of cell to another which help distribute nutrients and move the cell over the surface.
6. The study of the numerous interaction between microbes and host cell cytoskeleton is a very intense area of investigation on virulence mechanism.
All answers are correct. Therefore, option (E) is correct.
What is cytoskeleton?The cytoskeleton is a complex network of protein filaments that extends throughout the cytoplasm of eukaryotic cells. It plays a number of important roles in the cell, including providing structural support, helping cells maintain their shape, and assisting in the movement of organelles and other cellular components. The cytoskeleton is also involved in the process of cell division, or mitosis, which is the process by which a single cell divides into two daughter cells.
The cytoskeleton is composed of three types of protein filaments: microtubules, microfilaments, and intermediate filaments. Microtubules are long, thin protein fibers that form a kind of scaffolding within the cell. Microfilaments, which are made of actin proteins, are thinner than microtubules and are involved in muscle contraction and cell movement. Intermediate filaments are thicker than microfilaments and provide structural support to the cell. Together, these three types of protein filaments form a system of tracks that can be used for transport within the cell.

You will be the expert: Imagine you are teaching a class on controlling microbial growth in the environment. To test your students, you will present them with a scenario including a site and some probably microbes present. They must design a strategy to eliminate harmful microbes from the area.
1A. Come up with a scenario/situation including a site and some probable microbes present.
1B. Come up with possible solution/analysis to that scenario/situation in order to eleminate harmful microbes.
Answer:
A possible scenario would be many rusty pipes with abundant soil in an abandoned area or house.
The probable microorganism would be clostritium tetani, which causes tetanus disease.
This clostridium is eliminated once the oxidized surfaces are exterilized, eliminated and cleaned with disinfectants.
In addition, it could be sprayed with disinfectant on the ground to kill the presence of possible spores of this bacterium.
Explanation:
Clostridium tetani is a bacterium that affects the central and peripheral nervous systems of humans.
Today there is a vaccine for this bacterium, which is called tetanus and is administered against a possible accident, surgical act or risk of having been inoculated with the bacteria.
The current tetanus vaccine has a longevity of 10 years in the human organism, once this period has passed, the booster should be given.
This bacterium coexists with other microorganisms in this environment with accumulations of soil and rust, which the most dangerous would be fungi (they trigger deep mycosis). An example of these fungi is: histoplasma capsulatum, responsible for generating histoplasmosis.
The scenario or situation including a site and some probable microbes present would be a controlled Laboratory.
The possible solution or analysis to that scenario in order to eliminate harmful microbes is fumigation.
Identification of microbes is critical in determining which microbial removal strategies will be used in a site.
The scenario or situation including a site and some probable microbes present would be a controlled Laboratory where microbes are isolated from the site via cultured methods. When carrying out microbial culture, the culture plates usually support the growth of a wide range of microorganisms. As a result, biochemical approaches may be used to distinguish one microbial population species from another. They may exist in various species of fungi, viruses, bacteria, protozoa, etc.
The elimination of microbes is dependant on the size of the area being analyzed. This is done by the application of formaldehyde to the area. Other methods include alcohol sterilization and heat sterilization for cleaning and sanitizing surfaces of the laboratory and equipment respectively.

d. Decrease salt intake
e. Decrease blood volume
f. Vasoconstriction
g. Increase peripheral resistance
h. Increase salt intake
i. Increase blood volume
j. Increase water reabsorption
Answer:
a. Decrease water reabsorption : decrease blood pressure.
b. Decrease peripheral resistance : decrease blood pressure
c. Vasodilation : decrease blood pressure
d. Decrease salt intake : decrease blood pressure
e. Decrease blood volume : decrease blood pressure
f. Vasoconstriction : increase blood pressure
g. Increase peripheral resistance: increase blood pressure
h. Increase salt intake: increase blood pressure
i. Increase blood volume : increase blood pressure
j. Increase water reabsorption: increase blood pressure
Explanation:
Total peripheral resistance: This term refers to the resistance offered by the vascular system to the blood flow. This resistance is a result of the friction between the blood and the vessel's walls. In other words, it is the opposition of the vessels to blood flow. The total peripheral resistance is the summary of all the bloody circuit resistances in the body. Those mechanisms that induce vasoconstriction conduce to an increase in total peripheral resistance, while mechanisms that induce vasodilation provoke a decrease in total peripheral resistance. Blood pressure: This term refers to the strength applied by the blood against the vessel walls as it flows. This pressure is determined by the bombed blood strength and the volume as well as by the vessel size and flexibility. Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others. Salt ingestion causes an increase in plasmatic osmolarity, stimulates thirst, and hence, water ingestion. Sodium retains water, expanding the blood volume and causing an increase in vessel pressure. The antidiuretic hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. By these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism´s needs. Kidneys control blood pressure in many ways. If the pressure is elevated, kidneys produce the loss of salt and water, normalizing arterial pressure. But if pressure is low, kidneys conserve water.Which of the following statements is true of soluble fibers? a. They are not viscous. b. They retain their tough texture after being cooked. c.
