Explain how a rollercoaster converts potential energy to kinetic energy

Answers

Answer 1
When the coaster ascends one of the smaller hills that follows the initial lift hill, its kinetic energy changes back to potential energy. In this way, the course of the track is constantly converting energy from kinetic to potential and back again.

What does this pyramid tell us about the population?

Answers

The answer is A. The population is growing.

The pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.

What is population?

Population is defined as the quantity or population of people living somewhere who are a particular social, cultural, economical, ethnic, or racial category. Making decisions can be aided by knowledge of how population parameters, such as size, regional distribution, age structure, or birth and death rates, vary over time.

The pyramid is used to show the growth in population of a country or population of the city. In the pyramid the growth of population is equal in both male and female population. The pyramid shows that the population of older generation is less than the population of younger generation peoples.

Thus, the pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.

what surfaces or objects on earth would reflect infrared light well?

Answers

Answer:

Infrared, sometimes called infrared light, is electromagnetic radiation with wavelengths longer than those of visible light. It is therefore invisible to the human eye.

Aside from water vapor, bodies of water on the surface of the Earth also absorb IR wavelengths well. Glass, wood, brick, stone, asphalt and paper all absorb IR radiation. While regular silver-backed mirrors reflect visible light waves, allowing you to see your reflection, they absorb infrared radiation.

PLEASE HELP!!!!! Describe in detail the process of dna replication

Answers

Answer:

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea

Answers

Answer: He performed dihybrid crosses

Explanation:

Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.

Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.

Does the difference in structure for arteries and veins make sense given then functions? Explain.

Answers

The walls of veins have the same three layers as the arteries. Although all the layers are present, there is less smooth muscle and connective tissue. This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the veins has less pressure than in the arteries. Hope this helps. Have a nice day.

Many scientists were skeptical of the endosymbiotic hypothesis because it didn't seem to fit into the theory of evolution as it was understood then. Between 1900 and 1950, biologists made many key discoveries in the field of genetics by focusing on small, random changes in DNA — mutations — that occur when a cell reproduces.

Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.
