Answer:
Density = Mass ÷ Volume (Displacement)
d = m/v
m = dv
v = m/d
So, the answer is density multiplied by volume.

Large deposits of Rock Gypsum and Rock salt have been found in Upstate NY. What does this tell you about the environment of Upstate NY in the past?
Answer: There must have been a body of water there previously, maybe prehistorically.
Explanation: Gypsum forms when the right materials in a body of water come together and water evaporates quickly.
Gypsum is an evaporite, which means its crystals form during the evaporation of water. Gypsum forms whenever evaporation crystallizes the necessary minerals. In the case of "desert roses" gypsum crystals found around the world in arid sites, formation occurs with evaporation as the level of the water table changes. Gypsum can also be formed diagenetically by oxidation. This chemical reaction occurs when oxidation of existing sediments causes gypsum to form and replace other minerals in the sediments.
Huge gypsum deposits called beds were formed when ancient tropic seas became concentrated through evaporation. Gypsum crystals formed in the mineral saturated sea brine and sank to the ocean bed.

Apply: Where in the Gizmo (and in real life) do the following energy conversions occur?
26.
Chemical to thermal to electrical current:
27
Gravitational potential to kinetic to electrical
current:
28.
Electrical to sound, radiant and thermal energy
29.
Nuclear to thermal to electrical current
Answer:
26. Coal is burned at a power plant
27. In dams.
28. Gas heater.
29. Nuclear power plant.
Explanation:
Coal is burned at a power plant where Chemical energy is converted into thermal and then into electrical current. In dams, water falls from higher altitude in which Gravitational potential is converted to kinetic energy by revolving of turbines which produces electrical current. in heater, electrical energy is converted into radiant and also heat or thermal energy while the nuclear thermal energy is converted into electrical energy and this happen in the nuclear power plant.
The energy conversion that occurs in the below-described processes are:
Coal that burnt in powerhouses.Water falling from dams. An electrical heaterNuclear power plant. What do you mean by Energy conversion?Energy conversion may be defined as a process by which one form of energy gets transformed into the other form and stored in it.
Coal that is burnt in powerhouses converts chemical energy to thermal energy and finally into electrical energy. Water that is falling from elevation undergoes gravitational potential to kinetic and when it is revolving the turbines to generate electricity, it may change from kinetic to electrical energy. An electric heater is an electrical appliance that converts electrical energy into heat. In nuclear power plants, Nuclear thermal energy gets converted into electrical energy.
Therefore, all the processes with respect to energy conversion are briefly described above.

What are Krebs cycle inputs and outputs?
Answer:
see below image:
Explanation:
inputs + their outputs listed in the image
The Krebs cycle continues when acetyl-CoA (2-carbon molecule) and oxaloacetate (4-carbon molecule) combine to form citrate (6-carbon molecule). Citrate is then converted into cis-aconitate, which is then converted into isocitrate. Following this step, one of the carbon atoms separates and is released as CO2.
What is Krebs cycle?The tricarboxylic acid (TCA) cycle, also known as the Krebs cycle or the citric acid cycle, is the primary source of energy for cells and an essential component of aerobic respiration.
The cycle converts acetyl coenzyme A (acetyl CoA available )'s chemical energy into the reducing power of nicotinamide adenine dinucleotide (NADH).
The Krebs cycle is powered by lipids (fats) and carbohydrates, both of which produce the molecule acetyl coenzyme-A. (acetyl-CoA).
This acetyl-CoA reaction is the first in an eight-step sequence of reactions known as the Krebs cycle, which takes place entirely within the mitochondria of eukaryotic cells.
The net energy output of glycolysis through the Krebs cycle for one glucose molecule is 4 ATP, 10 NADH + H+, and 2 FADH2.
Thus, these are the chief inputs and outputs of Krebs cycle.

Kaya had an organ transplant. She went to the doctor a week later, and the doctor did a blood test. Her lymphocyte count
had increased. She went to the doctor a month later for the same test, and her lymphocyte Count was higher. What is the
best explanation as to why her lymphocyte levels were increasing?
O Kaya was given antibiotics to prevent infections.
O Kaya's antigens were attacking the tissue.
O Kaya was not tissue typed prior to her surgery, and her body is mounting an immune response.
Kaya took her immunosuppressant drugs weekly, which increased her lymphocyte count?
The best explanation for why Kaya's lymphocyte levels were increasing is Kaya was not tissue-typed prior to her surgery, and her body is mounting an immune response. Therefore option 3 is correct.
Lymphocytes are a type of white blood cell that plays a crucial role in the immune response of the body. They are responsible for recognizing and targeting foreign substances, such as antigens, to protect the body against infections and diseases.
In Kaya's case, her lymphocyte levels increased both a week and a month after the transplant. This suggests that her immune system is responding to the presence of the transplanted organ.
The increased lymphocyte count indicates an ongoing immune reaction, which is typically characterized by the proliferation and activation of lymphocytes.

What is the purpose of DNA structure made of nucleotides
Answer:
DNA is made up of molecules called nucleotides.
Its unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA splits down the middle and becomes two single strands. These single strands serve as templates for building two new DNA molecules - each a replica of the original DNA molecule.
