Distance is a measure of how much ground has been covered by an object in motion. The object has been covered 70 km of distance in 4 hours. Option B is correct.
What is Distance?It is a measure of how much ground has been covered by an object in motion.Distance is directly proportional to the speed of the object.Displacement:It is a vector quantity that refers to the overall change in position of the object.It is defined as the straight line distance between the initial and final position of the object.Therefore, the object has been covered 70 km of distance in 4 hours.

what is causing global warming a an increase in plate tectonic movement be the reversal of Earth's magnetic poles see if influxes of cosmic radiation or changes in the composition of the atmosphere
Answer:
Changes in the composition of the atmosphere
Explanation:
Although this answer is very vague and generalized, it is the correct answer.
The increase in greenhouse gas emissions in the atmosphere from modern manufacturing and engineering has increase carbon dioxide and methane concentrations in the upper atmosphere. These gasses have a chemical composition that allows the absorption and release of longwave radiation back to the Earth's surface slowly increasing the global average temperature.
Scientist sometimes use DNA sequences such as these to determine the relatedness of different species. Which of the following is a necessary
on for scientists to use DNA sequences in this way?
Answer: A
Explanation: i took the test
The DNA of all organism contains the same bases. Thus, option A is correct.
What is the different features of DNA and RNA?DNA stands for deoxyribonucleic acid, while RNA stands for ribonucleic acid.
Both are nucleic acid is composed of three components such as nitrogenous base, sugar and phosphate molecule.
DNA has a long polymer of deoxyribose sugar and phosphate backbone having four distinct bases such as adenine, thymine, cytosine and guanine.
RNA has a polymer of a ribose sugar and phosphate backbone with four varying bases: uracil, cytosine, adenine and guanine.
DNA is present in the nucleus and mitochondria, while RNA is found in the cytoplasm, nucleus and in the ribosome.
DNA is stable under alkaline conditions, while RNA is not stable.
DNA self-replicating in nature while RNA does not replicate on its own.

A cell containing 10% salt is placed in a beaker of 30% salt. Is the solution is
the beaker hypertonic, hypotonic, or isotonic to the cell? *
Answer:
Hypertonic solution
Explanation:
Because a hypertonic solution occurs when more solutes are outside the cell than on the inside cell
A cell containing 10% salt is placed in a beaker of 30% salt. Is the solution is the beaker hypertonic to the cell.
What is in a hypertonic solution?Any external solution with a high solute content and a low water concentration in comparison to bodily fluids is referred to as a hypertonic solution. The net migration of water in a hypertonic solution will be from the body into the solution.
Hypertonic solutions include 10% salt content. A cell that is placed in a hypertonic environment experiences a net migration of water to the cell's exterior (from the higher water environment inside the cell). In reaction, the cell contracts.
A solution is said to be hypertonic if its salt concentration is higher than the salt concentration in the cells. The osmosis process allows water to pass through permeable cell membranes.

What does a vaccine do to help an immune system?
Answer:
A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
Explanation:
Basically it trains the body by giving it a little expirementation withthe sickness. After that, the body will learn how to properly fight or keep the sickness at bay.
Hope it helped!;)
A vaccine injects a little bit of whatever disease you want to protect yourself from. It's just enough that your immune system fights it off and becomes stronger against the disease.

What are our lungs made out of?
Answer:
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopies

why are some molecules polar and others non polar
Answer:
Polarity and Non-polarity of molecules depend upon the electronegativity. The theory of electronegativity lies in entire inorganic chemistry. The more electronegative an atom, the more it seeks electrons. If one atom is more electronegative than others, it can form an ionic bond or a polar covalent bond.
Explanation:
In the deep water where there is no sunlight, how do bacteria and plants create
their food?
Answer:
Bacteria and Plants use the process of chemosynthesis to create/make food using chemical reactions.
Explanation:
"Autotrophs that perform chemosynthesis do not use energy from the sun to produce food. Instead, they make food using energy from chemical reactions, often combining hydrogen sulfide or methane with oxygen. ... Bacteria that live in the deep ocean, near hydrothermal vents, also produce food through chemosynthesis."
