Why are scientific observations important?Scientific observations are used by scientists to collect and record data, which allows them to put forth and test certain hypotheses and theories.
Scientific observations are done in many ways – by human senses or with machines and tools like microscopes, digital scanners or amplifiers to enhance their vision or hearing.
Observations make what scientists call data and they inspire, support or deny a scientific theory or hypothesis.
Hence, Scientific observations are important as all scientific experiments begin with observations hence option 2 is the correct option.

The correct way to calculate population density is by dividing the total population by the land area.
A. True
B. False
Answer: True
Explanation:
To calculate the population density, you will divide the population by the size of the area.
Formula=Population Density = Number of People/Land Area.
The number of inhabitants, or the population divided by the area's size, determines the population density. Many creatures' distribution, growth, and migration can all be described using population density.
What is the population density?Population density is the number of individuals of a species in a specific geographic area.
It is computed by dividing the population, or the total number of people in a population, by the total amount of space, in this example, the land area.
Demographic data can be quantified and examined in relation to infrastructure, ecosystems, and human health using population density data.
High population densities are typically found in lowland plains, flat river basins and deltas, and volcanic regions with good soil.
Low population densities are typically seen in mountainous regions with steep slopes and poor soil.
Therefore, it is true to calculate population density is by dividing the total population by the land area.

Blood Blood has four main components:Plasma is a straw-colored fluid. It is about 90 percent water and 10 percent dissolved gases, salts, nutrients, enzymes, hormones, waste products, plasma proteins, cholesterol, and other important compounds. Parts of plasma help control body temperature, transport substances, and fight infection. Plasma proteins are involved in blood clotting.Red blood cells transport oxygen. Blood gets its red color from the iron in hemoglobin, a protein that binds oxygen in the lungs and releases it in the capillaries.White blood cells guard against infection, fight parasites, and attack bacteria.Platelets are cell fragments involved in blood clotting.

Ohm’s law describes the relationship between which quantities?
voltage, resistance, and ohms
resistance, current, and amperes
current, voltage, and resistance
amperes, ohms, and current
Answer:
voltage, current, and resistance
Explanation:
Ohm's law states the relationship between voltage, current and resistance. As per this law, the voltage in a circuit is the product of current and resistance.
What is Ohm's law ?Ohm's Law is a fundamental principle in electrical engineering and physics that describes the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit.
The law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. In mathematical terms, Ohm's Law can be written as:
V = I * R
where V is the voltage across the circuit, I is the current flowing through the circuit, and R is the resistance of the circuit. This law applies to all electrical circuits, including both DC (direct current) and AC (alternating current) circuits. Ohm's Law is a crucial concept in electrical engineering and is used to design and analyze electrical circuits.
