Heparin, a highly negatively charged glycosaminoglycan, is used clinically as an anticoagulant. It acts by binding several plasma proteins, including antithrombin III, an inhibitor of blood clotting. The 1:1 binding of heparin to antithrombin III seems to cause a conformational change in the protein that greatly increases its ability to inhibit clotting. What amino acid residues of antithrombin III are likely to interact with heparin
Answers
Answer:
Positively charged amino acids
Explanation:
Heparin is an acid polysaccharide that has a strong negative charge due to the sulfate groups on its glucosamine residues. This negative charge confers to heparin anticoagulant activity. The negatively charged groups in the heparin molecule can interact with positively charged (basic) residues, such as arginine (Arg) and lysine (Lys) of plasma proteins. For example, it has been shown that lysine amino acid residues of antithrombin III may be involved in the binding with heparin.

What is NOT a function of the reticular formation?
a. sleep b. breathing c. memory d. pain transmission
Answers
Answer:
c. memory
Explanation:
Memory is not a function of the reticular formation. Sleeping, breathing, and pain transmission all are the functions of reticular formation. Thus, the correct option is C.
What is reticular formation?
Reticular formation is a part of the pons region of brain which controls the sleep-wake cycle and also filters stimuli to separate out relevant background stimuli from irrelevant ones.
Reticular formation is one of the phylogenetically earliest parts of the brain and it is crucial for controlling some fundamental processes such as sleeping, breathing, and pain transmission.
The reticular formation is an essential process for the numerous activities of the brainstem. It is located strategically amid the significant nuclei in the brain cells and the nerve fibers that traverse it. The reticular formation looks like an intricate web network.
Therefore, the correct option is C.

Phage are viruses that must infect bacteria to reproduce. Viral genomes do not contain all the genes needed to produce all proteins necessary for DNA replication, RNA transcription, and protein translation; instead the viruses force bacterial proteins and enzymes to express phage genes instead of bacterial genes.
Phage are very adaptable, and their behavior depends on whether conditions are favorable or unfavorable for making more phage.
When bacteria are plentiful (favorable conditions), viral DNA within the bacteria remains separate from the bacterial chromosome, and the virus forces the bacteria to make more virus. When the amount of virus becomes too much for the cell to hold, the membrane ruptures, and viruses are released to infect surrounding bacteria. This is known as the lytic cycle.
When bacteria are scarce (unfavorable conditions), the viral DNA within the bacteria becomes integrated into the bacterial chromosome. The bacteria survive and are still able to reproduce; viral DNA is transmitted to daughter cells when the bacteria reproduces. This is known as the lysogenic cycle.
As you just read, phage depend on bacteria to reproduce. Phage can be maintained by infecting a culture of bacteria with a strain of phage, and then plating the bacteria on an agar plate to grow.
Suppose that you isolate two mutant strains of phage - one strain cannot enter the lytic cycle and the other strain cannot enter the lysogenic cycle. You also grow wild-type phage as a control. You see three different phenotypes:
A plate with no missing bacteria- the lawn of bacteria is intact
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles.
Based on what you know about what happens in each cycle, match the plating results with the identity of the strain.
Drag each plate into the correct category.
Answers
Answer:
A plate with no missing bacteria- the lawn of bacteria is intact----strain with lysogenic cycle.
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles---- lytic cycle
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles----- wild type phage.
Explanation:
The strain which cannot enter the lytic cycle having no missing bacteria on the plate because the virus remains inside the bacterial cell while on the other hand, the other strain that cannot enter the lysogenic cycle having no bacteria on the circle due to infection of virus spreads throughout the cells and no bacterial cell remains uninfected. One plate having some bacteria and some space having no bacteria due to virus of wild type that shows both cycles.

A prokaryotic organism is an organism that does not possess a membrane-bound nucleus that houses its genetic material. Organisms grouped under this domain are bacteria, archaebacteia etc.
According to this question, Fernanda goes for a blood sample because she felt sick. The result of the blood sampling shows that the cells of Fernanda contain a pathogen that seems to be made of small cells with no nucleus. This property describes a prokaryotic pathogen. Hence, the infection is most likely to be that of a BACTERIAL INFECTION.
Note that, a fungus is eukaryotic while a virus is considered non-living because it can only replicate in a living host.
Which of the following is a source of energy made from plant and animal remains?
Answers
In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
These are sometimes known instead as mineral fuels.
The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.
A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.

Two receptors bind to a same chemical messenger, but the concentration of this chemical messenger required to reach a certain number of bound messengers for one receptor is twice as great as the concentration for the other receptor. Thus, these two receptors have same ________, but different ________, to this chemical messenger
Answers
Answer:
binding specificity; affinity
Explanation:
Receptor binding specificity can be defined as the selectivity of a receptor to bind with a particular chemical messenger. Binding specificity is determined by the interaction between the chemical messenger and its specific receptor, as well as the binding site three-dimensional (3D) structure of both. This concept is contrary to receptor promiscuity, where a receptor can bind to many different chemical messengers. On the other hand, binding affinity can be defined as the overall affinity or avidity of binding. The binding affinity is determined by the accumulated strength of individual attractive forces between a chemical messenger (ligand) and its receptor.
