A liquid thermometer and an electronic thermometer are both properly placed in the same liquid. The liquid thermometer shows 53.4 degrees Celsius and the electronic thermometer shows 58.2 degrees Celsius. Which could best explain why they show different readings?
Answer:
The correct answer would be - electronic thermometer was not calibrated correctly
Explanation:
Every electronic equipment or instrument like an electronic thermometer, that measures something needs to be calibrated with a standard measurement or reference value to a new measuring device to establish a relationship.
Liquid thermometer measures based on the liquid's actual physical properties, that are present inside it so, calibration is not required.
Thus, the electronic thermometer was not calibrated correctly.

Even though a population in true hardy-weinberg equilibrium cannot exist, how can using the equation be useful?.
The Hardy-Weinberg equilibrium can be useful to discover the presence of evolutionary forces acting on a given population. It is used in population genetics.
What is the Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium is a theory stat states that genotypic and allele frequencies will remain constant in a population in absence of different evolutionary forces.
These evolutionary forces include mutation, natural selection, migration and sample size.
The Hardy-Weinberg equilibrium may result useful for finding the causes that originated a change in allele and genotypic frequencies in a given population.

Describe one method for reducing nitrogen oxide emissions into the atmosphere from anthropogenic sources.
Answer:
One way of controlling NOx emissions is to use low-nitrogen fuels. Another is to modify combustion conditions to generate less NOx. Flue gas treatment techniques, such as selective cata- lytic reduction (SCR) processes, can remove NOx.
Explanation:
One method of keeping NOx emissions is to use low-nitrogen fuels. Another is to change combustion requirements to generate less NOx. Flue gas treatment techniques, such as selective catalytic reduction processes, can remove NOx.
How can we reduce the emission of nitrogen oxides into the atmosphere?
Nitrogen emissions can be decreased by making procedure changes (such as modifications to the combustion process) or by installing air pollution control equipment (such as selective non-catalytic reduction (SNCR) or selective catalytic reduction (SCR)).
Thus, selective catalytic reduction processes can remove NOx.

List the three processes involved in the formation of urine in order. 1. tubular secretion 2. tubular reabsorption 3. glomerular filtration
In this question, We list the three processes involved in the formation of urine in order. 1. glomerular filtration 2. tubular reabsorption 3. tubular secretion
Steps of urine production
Inside the renal capsule, the blood undergoes strong pressure, which causes the output of the so-called glomerular filtrate (or initial urine), a liquid similar in composition to blood plasma. This process is called filtration. The filtrate is mainly made up of water, urea, glucose, salts and amino acids. It is important to remember that blood cells and some larger proteins do not pass into the capsule.
After leaving the renal capsule, the filtrate passes through the length of the nephric tubule and water and useful substances are reabsorbed into the body. These substances go back into the bloodstream. Most of the reabsorption occurs in the proximal tubule region.
In the tubules, the process of secretion also takes place, in which some metabolites and drugs are carried from the blood vessels into the tube.
After passing through the entire nephric tubule, we have the filtrate transformed into urine.
With the information obtained, we list the three processes involved in the formation of urine in order. 1. glomerular filtration 2. tubular reabsorption 3. tubular secretion

supposed the primary producers in the energy pyramid shown contain 76500 kj of energy. how much would be available for the organisms on the tertiary level ?
Answer:
76.5Kj
Explanation:
A food chain consists of different trophic levels of organisms ranging from the PRODUCERS to the TERTIARY CONSUMERS. According to the pyramid of energy, only about 10% of energy is available for use for the next trophic level as majority of the energy (about 90%) is lost as heat.
Hence, if the primary producers in the energy pyramid contains 76500kJ of energy, the following energy would be available for each trophic level.
Primary producers: 76500kJ
- 10% of energy will be available to the primary consumer = 10/100 × 76500 = 7650kJ
- 10% of energy (7650kJ) will be available to the secondary consumer = 10/100 × 7650 = 765kJ
- 10% of energy (765kJ) will be available to the tertiary consumer = 10/100 × 765 = 76.5kJ
Hence, 76.5kJ of energy will be available for organisms at the tertiary level.

differentiate nebular hypothesis and solor nebula theory
Explanation:
The Nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests that the Solar System formed from gas and dust orbiting the Sun. The theory was developed by Immanuel Kant and published in his Allgemeine Naturgeschichte und Theorie des Himmels ("Universal Natural History and Theory of the Heavens"), published in 1755 and then modified in 1796 by Pierre Laplace.
The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas. It is believed that the sun, planets, moons, and asteroids were formed around the same time around 4.5 billion years ago from a nebula.

A. Passive transport
B. Endocytosis
C. Exocytosis
D. Active Transport
Answer:
Explanation:
Endocytosis
The process shown in the image is of Endocytosis. It is a type of cellular transport through which different substances enters the cell. Thus, the correct option is B.
What is Endocytosis?
Endocytosis is a process during which substances are brought inside the cell. The materials which are to be internalized are first surrounded by the plasma membrane. The plasma membrane in-folds across the substances to form a vesicle.
The vesicle formed by the in-folding of the plasma membrane then fuses with the membrane and buds off into the cell. Thus, the substance are delivered inside the cell.
Endocytosis is of two types- pinocytosis (cell drinking) and phagocytosis (cell eating). Examples of endocytosis includes uptake of cholesterol-bound low density lipoproteins, and recycling of iron-bound transferrin, etc.
Therefore, the correct option is B.
