Which statements describe the effects of indoor pollution? Select two options.
Ultrafine particles cause poor health.
Nose hairs and mucus catch all the particles before they reach the lungs
Ultrafine particles are absorbed by the lungs when people breathe.
Ultrafine particles contribute to more than 20,000 deaths per year in the United States.
Most ultrafine particles can be seen with the unaided eye.
Answers
Answer:
A and C
Explanation:
The negative health impacts of indoor pollution are caused by ultrafine particles that are inhaled and absorbed by the lungs. So, the correct options are A and C.
What are Indoor pollution?Indoor air pollution, which can be as much as ten times worse than outside air pollution, is indeed the degradation in indoor air quality caused by hazardous chemicals and other elements. This is because enclosed rooms encourage the accumulation of possible contaminants more than do open ones.
The main contributors to indoor air pollution include: Bioaerosols, building materials, and combustion Although radon, asbestos, pesticides, toxic substances, organic volatile compounds, and environmental tobacco smoke are all regarded as serious indoor pollutants in industrialised countries, developing countries are primarily affected by the combustion byproducts of biomass fuels.
The negative health impacts of indoor pollution are caused by ultrafine particles that are inhaled and absorbed by the lungs.
Therefore, the correct options are A and C.

A. High levels of thyrotropin releasing hormone.
B. High levels of thyroid stimulating hormone.
C. High levels of thyroxin and triiodothyronine.
D. All of the above would tend to increase the size of the thyroid gland.
E. None of the above would tend to increase the size of the thyroid gland.
Answers
Answer:
Option A
Explanation:
Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is
a) over- or underproduction of thyroid hormones
b) Nodules in the glans
Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing the thyroid to swell
Thus, Option A is correct

ans:Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.
How could gravity affect the water cycle?
ans:It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

*Earth Science* Active continental margins where the plate boundary is ocean-continent convergent are characterized by accretionary wedges.
True or false?
Answers
The correct answer is True
Explanation
An accretion wedge is an area where deformed sediment accumulates that occurs at a convergent edge at the boundaries of subduction plates (ocean-continent). This process occurs when sediments from the oceanic crust accumulate to the block of continental crust produced. by the subduction movement of the oceanic crust. So, the correct answer is True.

Recall in class the example of incorporating heavy or light nitrogen labels into DNA to investigate how DNA is replicated. Imagine if, instead of labeling DNA, the experiment used heavy labeled RNA bases. What would be the outcome if you examined the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases?
Answers
Answer: You would not notice any difference or any labeled base, because RNA is not used to make DNA.
Explanation:
DNA is a molecule that contains the genetic information in all living things. The molecule consists of two strands that wind around each other to form a double helix structure where the strands are joined by hydrogen bonds. It is a nucleotide polymer where each nucleotide consists of a sugar called deoxyribose, a nitrogenous base (which can be adenine, thymine, cytosine or guanine) and a phosphate group (derived from phosphoric acid). What distinguishes one polynucleotide from another, is the nitrogenous base and thus the sequence of DNA is specified by naming only the sequence of its bases. The sequential arrangement of these four bases along the chain is what encodes the genetic information.
Consider that DNA replication is semi-conservative, which means that each strand of the DNA double helix functions as a template for the synthesis of a new complementary strand. This process leads from one starting molecule to two "daughter" molecules, in which each new double helix contains one new and one old strand. Then, if nitrogen tags are incorporated into the DNA, they will register on the old strand of the new DNA molecule.
On the other hand, RNA (ribonucleic acid) is a molecule similar to DNA but has only one strand and consists of a sugar (ribose) and alternating phosphate groups. Attached to each sugar is one of the four bases adenine, uracil, cytosine or guanine. The process of RNA synthesis, called transcription, consists of making a complementary copy of a piece of DNA. During this process, an enzyme called ARN polymerase, adds nucleotides that are complementary to the DNA strand. Then, this new RNA strand has new nucleotides. Thereby, if you examine the DNA strands after completion of DNA replication in the presence of heavy labeled RNA bases, you would not notice any difference or any labeled base, because RNA is not used to make DNA.

A scientist injects a drug called rifampicin, which inhibits RNA synthesis, into a bacterium. What is the most likely direct result of this alteration?
The bacterial DNA will stop replicating.
The bacterial DNA will replicate in an uncontrolled way.
The process of protein synthesis will stop in the bacterium.
Answers
The most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.
What is Rifampicin drug used for?The drug Rifampin is used to treat tuberculosis (TB) in many different parts of the body. It is also used by patients who have meningitis bacteria in their nose or throat who do not show symptoms of the infection to prevent the spread of the bacteria to other patients.
Rifampin specifically inhibits bacterial RNA polymerase. It is an enzyme that is responsible for DNA transcription, by forming a stable drug-enzyme complex with a binding constant of 10(-9) M at 37 C. The corresponding mammalian enzymes are not affected by rifampin.
Therefore, the most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.
