Answer:
The warmer water will mix with the cold water because it will migrate to the surface.
Explanation:
If hot water and cold water are poured in the same place, it means that they will occupy the same space. However, hot water has a lower density than cold water, which means that hot water molecules are lighter and will tend to rise towards the surface.
However, when migrating to the surface, the hot water molecules will pass between the cold water molecules, causing the two waters to mix. In this process, the hot water will transfer heat to the cold water and cool until the two waters have the same temperature.
What characteristic of double-stranded DNA determines the ability of one strand to make an exact copy of the other strand?
O complementary pairing of bases
O hydrogen bonding between strands
O ability of bases to be connected in any order
O location of the base pairs in the center of helix
Answer:
The correct answer is ''complementary pairing of bases''
Explanation:
The double-stranded DNA with the complementary nitrogenous bases that are located inwards and establish non-covalent bonds (or attractive forces) to each other that maintain the structure of the molecule. Deoxyriboses (sugars) and phosphate groups constitute the columns of the molecule. When the cell divides, each new cell that is formed must carry all the genetic information that determines its characteristics and functions. For that, before dividing, DNA must replicate, that is, generate a copy of itself. During replication, the DNA molecule unwinds, separating its chains. Each of these will serve as a template for the synthesis of new DNA strands. The double-stranded DNA structure proposed by Watson and Crick (1953) suggested several important properties of the hereditary material: Complementarity rules of the nitrogenous bases A-T and G-C suggest a simple way of replication of the hereditary material. This simple form of replication is called a semi-conservative method. When DNA replicates, its two helices separate and each one of them serves as a template to synthesize a new helix following the pairing rules of nitrogenous bases.

You will need to create a blueprint to design your own Rube Goldberg device. Then, you will need to BUILD IT and complete each of the sections of the lab report (provided later). Your Rube Goldberg device design must include:
A task you are looking to accomplish at the end (ex: turning on a light, opening the fridge, etc)
at least 6 stages
at least four energy transformations to perform a simple task (ex: kinetic, potential, chemical energy, radiant energy, sound energy, electrical energy, thermal energy, magnetic, etc)
Part One: Draw It
If you draw your device, you will need to turn in your device design along with a written description of how each step works. You may choose to draw it freehand and scan or photograph the drawing, or you may use a computer program to digitally create your device. You can either write a description down in a box at each stage on the drawing OR submit the written descriptions separately. Insert below, if possible.

Layers of shells from once-living organisms and sediment are cemented together and turn to rock, storing the carbon in stone called limestone. This process moves carbon atoms from the biosphere to the geosphere (lithosphere).
Answer:
Sedimentation.
Explanation:
The process that is responsible for the movement of carbon atoms from the biosphere to the geosphere is called sedimentation. Carbon enters the geosphere or lithosphere through the biosphere when dead organic matter becomes incorporated into the soil that turns the shells of calcium carbonate to become limestone through the process which is called sedimentation. This sedimentation process is very necessary for the formation of different types of minerals such as limestone, fossil fuels etc.

In today's world, a phone call to 911 is designed to ensure that emergency services, including fire, law enforcement, and emergency medical care is accessible to all individuals who find themselves in an emergency. Traffic laws establish that drivers are to move their vehicles to the right of the road and come to a stop in order to allow an emergency vehicle to pass. Emergency medical care is recognized as vital to helping to keep people safe and healthy. Yet, emergency medical services (EMS), as we know them today were only formally established in United States the 1970s. How did the country survive for so long without these services? What did citizens do if they had an emergency? What changes took place that made EMS a part of the emergency care provided for citizens? In this chapter, you will learn about the history and development of EMS in the United States.

Read the following passage from the Biology Department at University of California, Berkeley.
Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
Which of the following best describes how the population has evolved?
The population has not evolved because there was no change in allele frequencies.
The population has not evolved because it has grown.
The population has evolved because it has grown.
The population has evolved because there was a change in allele frequencies.
Answer:
the last one sorry if i'm wrong
Explanation:
According to the passage from the Biology Department at University of California, Berkeley.Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.
The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
What is population?The term population reffered to the total number of people living in a particular given area.The population of an organism can't survive if it exceeds it's carrying capacity.
The causes that affect population growth animals that if there are more plants than usual in area, populations of animals that eat that plant may increase.
If animal population increases the population that eat that animal might also increase.
The effects of animals population can be dangerous and when population exceed the carrying capacity of their environment, animal suffer of malnutrition and disease.
When predictors became scarce due to over population, the weekar species of animal start or die in other ways .
The accurate description of the growth of a natural animal population is limited by environmental factors.
Therefore,The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
