Oxygen rich blood returns from the lungs to the heart. Which 2 systems are most directly involved in this process.
Respiratory and circulatory
Excretory and digestive
Circulatory and excretory
Digestive and respiratory
Answer:
Respiratory and circulatory
Explanation:
The Circulatory System Works in Tandem with the Respiratory System. The circulatory and respiratory systems work together to sustain the body with oxygen and to remove carbon dioxide. Pulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs.
The two systems which are most directly involved in this process are respiratory and circulatory systems.
What do you mean by oxygen-rich blood?In the lungs, oxygen is put into the blood, and carbon dioxide is taken out of the blood during the process of breathing. After the blood gets oxygen in the lungs, it is called oxygen-rich blood.
During the whole process of breathing, the respiratory and circulatory systems play a major role in the separation of oxygen-rich and oxygen-poor blood.
Therefore, the two systems which are most directly involved in this process are the the respiratory and the circulatory systems.

Goiters may occur due to iodine insufficiency, but other causes are possible. Which of the following would NOT tend to result in increased size of the thyroid gland?
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.
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

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.
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 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.
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.

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.
