A. uses two thermometers; a dry and wet bulb
B. points in the direction winds are coming from
C. uses frequency waves to track particle movement
D. used to help track air masses and fronts
E. carried with a weather balloon
Answer: The correct matching sequence is:
1 -D , 2-C, 3-E, 4-B , 5-A
Explanation:
Weather maps/satellite:These are the satellites used to monitor the climate on the Earth in day and night.Like moc=vment of clouds, El Nino. La Nina ertc
Doppler radar is a system used to track the velocity or motion of the rain , storm or precipitation.It emit microwave signals to check the change in frequency of the wave due to the motion of the particles.
Radiosonde is an instrument carried away by balloon or any other means into different layers of atmosphere and sends information via radio.
Wind vane is an instrument used to show the direction of the wind. P
Psychrometer is an instrument used to measure atmospheric humidity.It consist of two thermometer that is wet bulb thermometer and dry bulb thermometer.
Match each weather instrument with its description.
Warm water is less dense than cold water.
The density is the same for warm and cold water.
The density will sometimes be higher for warm water and other times higher for cold water.
B. 8
C. 3
D. 4
Red blood cells are primarily formed in the bone marrow, specifically the red bone marrow. The process of producing these cells, known as hematopoiesis, begins at the embryonic stage and continues throughout a person's life, with adult hematopoiesis being largely restricted to certain bones in the body. New red blood cells are continuously produced due to their relatively short lifespan.
Red blood cells are formed in the bone marrow, specifically in the red bone marrow which is a loose collection of cells where hematopoiesis or the production of blood cells occurs. This crucial process of forming blood cells, including red blood cells, is introduced in the embryonic stage in the yolk sac. However, as the embryo develops, this function is taken over by the spleen, liver, and lymph nodes, with the bone marrow eventually assuming most hematopoietic functions. The red blood cells, along with white blood cells and platelets, are all produced in the red bone marrow.
In children, this process can occur in the cavity of long bones, but in adults, it is largely restricted to certain bones such as the cranial and pelvic bones, the vertebrae, the sternum, and parts of the femur and humerus. The lifespan of these cells is relatively brief, so new ones must be continuously produced to maintain healthy bodily functions.

By utilizing stoichiometry, we can determine that the given volume and molarity of acetic acid (HC2H3O2) would produce approximately 3.65 grams of carbon dioxide (CO2). The calculation involves determining the moles of HC2H3O2 used, which equals the moles of CO2 produced, and converting that to grams using the molar mass of CO2.
The amount of carbon dioxide produced can be determined through stoichiometry, using the provided balanced chemical equation and molarity (M) of the acetic acid HC2H3O2. According to the balanced chemical equation, one mole of NaHCO3 reacts with one mole of HC2H3O2 to produce one mole of CO2. In other words, the moles of HC2H3O2 used equals the moles of CO2 produced.
First, calculate the moles of HC2H3O2 by multiplying the given volume (0.100 L) by its molarity (0.83 mol/L): 0.100L x 0.83 mol/L = 0.083 mol.
So, according to the stoichiometric ratio, 0.083 mol of HC2H3O2 would produce 0.083 mol of CO2. If you want your answer in grams, note that the molar mass of CO2 is approximately 44.01 g/mol. Multiply the moles of CO2 by its molar mass: 0.083 mol x 44.01 g/mol = 3.65g.
So, the amount of CO2 produced would be 3.65 grams.

C. variable
D. constant
Answer:
correct answer is option C (constant)
Explanation:
Radioactive decay of radioactive element occur at known rates, the unit of radioactive decay is called half-life. The amount of time a radioactive element takes for half of the parent atoms to decay is known as half-life of a radioactive element
During Radioactive decay radioactive elements emits a particle. It's impossible to predict exactly when a given atom of a substance will emit a particular particle, but the decay rate of a radioactive element over a long period of time is constant.
By radioactive decay scientist can determine the age of that particular element. If radioactive decay will vary than age cannot be determined from radioactive decay.
