Choose the true statement about sources of air pollution in the United States.
a. Natural sources contribute over half of air pollution emissions.
b. Mobile sources are non-point sources of air pollution.
c. Air pollution levels remain fairly consistent across the country.
d. Lead in the atmosphere is the result of refrigeration and using aerosol sprays.
The true statement about sources of air pollution in the United States is that mobile sources are non-point sources of air pollution.
Answer choice b is correct. Mobile sources, such as cars, trucks, and other forms of transportation, are considered non-point sources of air pollution. Non-point sources refer to dispersed and widespread sources that contribute to pollution over a large area. Mobile sources emit pollutants such as nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter (PM), which contribute to air pollution.
Answer choices a, c, and d are incorrect. Natural sources do contribute to air pollution, but they do not account for over half of the emissions. Air pollution levels vary across the country depending on various factors such as industrial activities, population density, and geographical conditions. Lead in the atmosphere is primarily the result of past emissions from activities like leaded gasoline combustion and industrial processes, rather than refrigeration or aerosol sprays.
In summary, mobile sources are non-point sources of air pollution in the United States, emitting pollutants that contribute to the overall air pollution levels in the country.

Los insectos polinizadores son especies clave en muchas comunidades que interacción interespecífica se da entre estos insectos??
Answer:
Competencia interespecífica
Explanation:
Los polinizadores son organismos esenciales para el equilibrio de las comunidades silvestres y el mantenimiento de la biodiversidad existente en el planeta. Los insectos (especialmente las abejas) representan el grupo de polinizadores más importantes, estos organismos consumen el néctar como alimento y simultáneamente son utilizados por plantas para reproducirse mediante el trasporte del polen de una flor a otra. Los insectos polinizadores usualmente visitan muchos diferentes tipos de plantas y, a su vez, estas plantas son polinizadas por diferentes grupos de insectos polinizadores. Como consecuencia de esto último, entre polinizadores se establece una competencia interespecífica por un recurso (es decir, el polen) el cual a priori podría considerarse limitado. Sin embargo, ha sido demostrado que las redes e interacciones entre plantas y polinizadores están organizadas de tal modo que la competencia interespecífica entre polinizadores se encuentra reducida drásticamente, siendo incluso beneficiosas para las especies que la componen. Estos resultados se encuentran soportados por el análisis de información a campo la cual demuestra como redes entre polinizadores y plantas son similares en diferentes ecosistemas/continentes y también porque cuando tales conexiones gozan de buena salud se observa un aumento de la biodiversidad en las comunidades ecológicas.
which of the following is needed for cytokinesis in plant cells but not animal cells? (select all that apply!)
a.Actin b.Microtubules c.Kinesin d.Dynein e.Myosin
Actin and Myosin are needed for cytokinesis in plant cells but not animal cells, options a and e are correct.
Cytokinesis, the division of the cytoplasm following nuclear division, differs between plant and animal cells. While animal cells rely on a contractile ring composed of actin and myosin filaments to pinch the cell membrane inward, plant cells have a distinct process due to the presence of a rigid cell wall. In plant cells, cytokinesis involves the formation of a cell plate, which eventually develops into a new cell wall that separates the daughter cells.
This process requires actin filaments for guidance and deposition of materials, as well as myosin to assist in the movement and organization of vesicles involved in cell plate formation. Microtubules, kinesin, and dynein are involved in various cellular processes but are not specifically required for cytokinesis in plant cells, options a and e are correct.

Antibody-mediated immunity works mainly against --EXTRACELLULAR** pathogens, which include any bacteria, fungi or viruses that are in the extracellular fluids of the body. B cells respond to unprocessed antigens, but their response is more intense if they process the antigen and receive costimulation by --helper-- T cells. Once activated, B cells produce clones of --plasma-- cells and memory cells which reside in lymphatic tissues (such as MALT, lymph nodes and spleen). Plasma cells produce --antibodies--, which leave the lymphatic tissue and circulate in body fluids. Antibodies can be grouped into --five-- classes each with specific biological roles. Actions of antibodies include neutralization, immobilization, agglutination and precipitation of antigen. In addition, antibodies can activate --complement-- and enhance phagocytosis.
Antibody-mediated immunity targets extracellular pathogens through the production of specific antibodies that neutralize, eliminate, and enhance immune responses, providing defense against bacteria, fungi, and viruses in the body.

Plasma cells produce antibodies, which leave the lymphatic tissue and circulate in body fluids. Antibodies can be grouped into five classes, each with specific biological roles.
The five classes of antibodies, also known as immunoglobulins (Ig), are IgM, IgG, IgA, IgE, and IgD. IgM is the first antibody produced during an immune response and is effective in activating complement and agglutination. IgG is the most abundant antibody and provides long-term immunity by neutralizing toxins and promoting opsonization for phagocytosis. IgA is found in bodily secretions like saliva, tears, and breast milk, providing localized defense on mucosal surfaces. IgE is involved in allergic reactions and defends against parasites. IgD's function is not fully understood but it is believed to play a role in B cell activation.
Actions of antibodies include neutralization, where they bind to and block the activity of pathogens, immobilization by preventing pathogen movement, agglutination by clumping pathogens together for easier elimination, and precipitation of antigens out of solution. In addition, antibodies can activate complement, a group of proteins that help destroy pathogens, and enhance phagocytosis by marking pathogens for engulfment by immune cells.

Which of the following support the theory of evolution? Pick three out of the four.
Group of answer choices
Fossils
Faunal Succession
Biogeography
Young Earth
Three out of the four that support the theory of evolution are Fossils, Biogeography, and Faunal Succession. Options B, D, and C are the correct answers.
The theory of evolution is a scientific theory that explains how organisms change or evolve, over time. In this theory, organisms produce more offspring than can survive in their environment. Organisms in the past are not the same as those found today and the solid evidence is provided by Fossils and they show a progression of evolution.
The evolution is reflected by the unique features of island species and geological change and the global distribution of organisms is studied in Biogeography. The principle which states that flora and fauna are preset in sedimentary rock strata in the form of fossils and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances is known as Faunal Succession.

what is the effect of the abnormal protein on tissue function in duchenne muscular dystrophy and skeletal muscle tissue?
Answer:
Lack of the dystrophin protein in muscle cells causes them to be fragile and easily damaged. DMD carriers are females who have a normal dystrophin gene on one X chromosome and an abnormal dystrophin gene on the other X chromosome. Most carriers of DMD do not themselves have signs and symptoms of the disease, but a minority do. Symptoms can range from mild skeletal muscle weakness or cardiac involvement to severe weakness or cardiac effects and can begin in childhood or adulthood.
Explanation:
suppose two parents, a father with the genotype aabbccddee and a mother with the genotype aabbccddee, want to have children. assume each locus follows mendelian inheritance patterns for dominance.
When considering the genotype of the parents aabbccddee and aabbccddee, it can be concluded that all their offspring would be of the same genotype aabbccddee.
Same genotype is because the parents are homozygous, meaning they carry two copies of the recessive allele at each locus that has two alternative alleles.Based on the information given, all of the children will inherit two recessive alleles at each locus because the parents have only recessive alleles.
Mendelian inheritance states that traits are inherited from parents in a predictable manner.
The father's aabbccddee genotype means that he is homozygous recessive for every locus. The mother's aabbccddee genotype also means that she is homozygous recessive for every locus.The Punnett square, on the other hand, is used to determine the potential genotypes of the children.When two parents are homozygous for the recessive allele, their offspring is also homozygous for the recessive allele. In this case, it means that all of their children will inherit two copies of the recessive allele at each locus.
Therefore, all of their children will have aabbccddee genotype.

A scientist studying the effects of radiation on DNA performs an experiment in which she exposes a sequence of nitrogen bases found in DNA to radiation. The DNA before and after the radiation is shown below.
Use the evidence to determine whether a mutation has occurred, and if so, interpret that mutation in the answer sheet provided
Before Exposure: ATCGTCA; After Exposure: ATTCGTCA
A. No mutation has occurred to the DNA sequence.
B. A nitrogen base has been deleted from the DNA molecule.
C. A nitrogen base has replaced another nitrogen base in the DNA molecule.
D. A nitrogen base has been added to the DNA molecule.
Answer:
D. A nitrogen base has been added to the DNA molecule.
Explanation:
You can see that the sequence for the nitrogen bases are in the exact same order after the exposure, this rules out A. You can count how many bases there are, 7 before and 8 after so it cannot be B. Lastly, given that they are in the same order as were before and that a base has been added, you can see that no bases were replaced (so not C) and that D is your answer.
