Option c is Correct. When suspicious cells are found in the blood stream, phagocyte immune cells are the first to become active.
The innate immune system's neutrophils are regarded as the initial defense. The blood is carried by neutrophils and macrophages, which remain in tissues and keep an eye out for any concerns. Both cells have the ability to "eat" bacteria and, in the event of a problem, to interact with other immune cells.
Due to IgM's ability to be expressed without isotype switching, it is always the first antibody to be produced in a humoral immune response. Neutrophils play a crucial role in the initial response to injury because they act as the body's initial line of defense against microbes within 10 minutes of the injury. These early IgM antibodies are created before somatic hypermutation of B cells, which is why they tend.

Now write four additional questions about HIV/AIDS that could help strengthen your argument in the presentation
HIV/AIDS is an infectious disease caused by the Human Immunodeficiency Virus which causes severe damage to the immune system.
1. How is HIV transmitted?
HIV is most often spread through unprotected sexual intercourse, as well as through blood transfusions and sharing of needles or syringes contaminated with HIV-infected blood.
It is also possible for a mother to pass HIV to her child during pregnancy, childbirth, or breastfeeding. However, activities such as hugging, shaking hands, or using the same toilet are not known to transmit HIV. HIV can be easily spread through contact with infected bodily fluids such as semen, vaginal fluids, or blood.
2. What are the signs and symptoms of HIV?
At the initial stages of HIV infection, one may experience flu-like symptoms such as fever, headache, swollen lymph nodes, joint and muscle pains, rash, and sore throat. As the virus progresses, more advanced signs may arise, such as extreme fatigue, sudden weight loss, yeast infections, shingles, and fever lasting more than 10 days.
3. What is the distinction between HIV and AIDS?
HIV is a virus that can weaken the immune system over time, and if left untreated can lead to AIDS. AIDS is the most advanced stage of HIV infection and is characterized by the presence of certain illnesses and a weakened immune system. HIV itself does not cause any symptoms, but can eventually cause a person's immune system to weaken to the point that they develop AIDS.
4. What medications are used to treat HIV?
Antiretroviral therapy (ART) is the main form of treatment used to manage HIV. This treatment uses a combination of medications that work to reduce the amount of virus in the body to an undetectable level, stopping it from replicating and spreading. By achieving this undetectable level, the risk of transmitting HIV to others is greatly reduced.

genes that are likely inherited together due to their physical proximity
The versions (alleles) of those gene that are on the same chromosome will typically be inherited as a pair most of the time.
This is because genes that are sufficiently close to one another on a chromosome would tend to "stay together." The term genetic linkage refers to this phenomena.
The likelihood of two genes inheriting together increased depending on how close they were to each other on a chromosome. On the other hand, genes on the very same chromosome that were more apart from one another were much more likely to be split apart during recombination. the propensity for genes or DNA segments that are tightly spaced across a chromosome to separate and, as a result, inherit together during meiosis.

how can having a large population keep the population in hardy weinberg equilibrium
The Hardy-Weinberg equilibrium is a theoretical model that describes genetic makeup of a population in equilibrium. Equilibrium is maintained by the balance of five factors: mutation, selection, migration, genetic drift, and random mating.
How can having large population keep the population in Hardy Weinberg equilibrium?One of the factors that can prevent the population from deviating from Hardy-Weinberg equilibrium is large population size. This is because in large population, effects of genetic drift are greatly reduced. Genetic drift is the random fluctuation of allele frequencies that occur in small populations and can lead to a deviation from Hardy-Weinberg equilibrium.
In a large population, any random fluctuations in allele frequencies are likely to be small and quickly counterbalanced by large number of individuals carrying different alleles. So, large population reduces the chance of genetic drift and thus maintain the equilibrium.

The majority of land animals were dinosaurs. much of the Cretaceous period saw higher sea levels than at any other time.
The final stage dinosaur extinction was caused by an asteroid collision rather than volcanism. As a result of an accelerated plate collision that occurred during the Cretaceous, mountains grew along North America's western border. The Gulf coast basin began to recede as these mountains rose, and seawater started to move northward into the increasing western interior. The Arctic region also started to flood with marine water. In average, the climate during the Paleolithic Era was substantially warmer than it is today—possibly the warmest globally during the whole Phanerozoic Eon.

If an average lake trout weighs 4,500 g, what is the total mass of PCBs in a trout in the Great Lakes?
The amount of PCBs in a trout in the Great Lakes can vary drastically based on the specific lake and the age and health of the fish. Generally, PCB levels are much higher in the older, larger fish, and as such, the total mass of PCBs in a 4,500 g lake trout in the Great Lakes can range from 1-7 mg. However, due to the large size of the trout, the total mass of PCBs can be as much as 7 mg, which is enough to negatively affect its health.
PCBs (polychlorinated biphenyls) are a man-made chemical compound found in many environments, including the Great Lakes. PCBs have been linked to a variety of health concerns, including cancer and reproductive problems. As such, they are of great concern in the Great Lakes, where they are known to bioaccumulate in fish.
To calculate the total mass of PCBs in a lake trout in the Great Lakes, one must first determine the average concentration of PCBs in lake trout in the Great Lakes. The United States Environmental Protection Agency (EPA) has established an acceptable concentration of PCBs in the Great Lakes of 0.09 parts per million (ppm). Therefore, an average lake trout in the Great Lakes contains 0.09 ppm of PCBs.
The total mass of PCBs in a lake trout in the Great Lakes can then be calculated using the following equation:
Total mass of PCBs (in grams) = (Average lake trout weight) x (Average PCB concentration in the Great Lakes)
Therefore, for an average lake trout weighing 4,500 g, the total mass of PCBs in the Great Lakes would be 4,500 x 0.09 = 405 g.

Exocrine secretion is the type of secretion that has an extracellular effect, such as the digestion of food.
Exocrine glands secrete their products into ducts, which then transport the secretions to the site of action. Examples of exocrine glands include the salivary glands, the pancreas, and the glands that secrete digestive enzymes into the small intestine. These secretions act outside of the cell and have a direct effect on the external environment.
Digestion is a good example of an exocrine function, where enzymes are secreted by glands such as the pancreas and salivary glands into the small intestine to break down food molecules. The enzymes secreted by these glands are not only specific to certain types of molecules but also specific to certain regions of the gut, thus ensuring an optimal digestion.
On the other hand, endocrine glands secrete hormones that act on target cells through the bloodstream, which have a more systemic effect.

What is the big thing that waste water consumes when it is broken down in a river? answer choices. Nitrogen. Oxygen. Kinetic energy. carbon dioxide
Oxygen s the big thing that waste water consumes when it is broken down in a river.
When sewage or agricultural runoff is discharged into a river, it contains a range of contaminants, including organic materials. Aerobic respiration is the process by which microorganisms like bacteria and fungus break down this organic material. As the microbes break down the organic materials into carbon dioxide, water, and other byproducts, oxygen is needed for this process. As a result, the river's oxygen levels may decrease, which would reduce the variety and number of aquatic life, including fish and other organisms that require oxygen to exist.
The process of decomposition of waste water also requires the use of kinetic energy and nitrogen. Oxygen is thus acting as a oxidative agent in case of decomposition of materials as well.

When waste water breaks down in a river, it consumes a lot of oxygen.
When sewage or agricultural runoff enters a river, it carries a variety of contaminants, including organic materials. Aerobic respiration is the process by which microorganisms such as bacteria and fungi degrade organic matter. The microbes require oxygen to break down organic materials into carbon dioxide, water, and other byproducts.
As a result, the oxygen levels in the river may decrease, reducing the variety and number of aquatic life, including fish and other organisms that require oxygen to survive. The decomposition of waste water necessitates the use of kinetic energy and nitrogen. In the case of material decomposition, oxygen also acts as an oxidative agent.

if you wanted to grow up a large quantity of streptomycin resistant e. coli, what would you do next?
Select a colony of bacteria and grow it on a plate that has been exposed to streptomycin.
Inoculate an E. coli sample onto a plate that has tested positive for streptomycin to expose it to the antibiotic. Any colonies that expand will have a resistance mutation. Through nitrate respiration, streptomycin therapy promotes the development of E. coli.
We used the commensal E. coli to test the theory that a streptomycin-induced rise in Nos2 mRNA levels fuels the growth of E. coli in the mouse large intestine by nitrate respiration. Single nucleotide polymorphisms (SNPs) in the rpsL gene are most frequently associated with streptomycin resistance mutations in E. coli strains. The ribosomal protein S12, which is a component of the small (30S) subunit, is encoded by this gene.

In general , we Inoculate an E. coli sample on a plate that has tested positive for streptomycin to expose it to the antibiotic. For the colonies that expand will have a resistance mutation. Nitrate respiration, helps streptomycin therapy to promotes the development of E. coli.
Escherichia coli K-12 is known to carry the R-factor R1 or R6K which is resistant to streptomycin. This resistance is due to factor known as R-factor-coded enzymes that helps metabolizing the drug. Streptomycin also gets deactivated in two ways, that is adenylation or by phosphorylation and both reactions require adenosine 5′-triphosphate.
