How much more kinetic energy does your car have when it changes its speed from 16 km per hour to 80 km per hour

Answers

Answer 1

Answer:

The correct answer would be - 25 times more.

Explanation:

The kinetic energy of a moving object increases with the increase in the speed of the object. It is evident that the kinetic energy of a moving object increases as the square of its velocity or speed. It means if a car moves with the speed of 32 km/hr has four times as much kinetic energy as the car moving with 16 km/hr.

Similarly, if a car changes its speed from 16 to 80 km/hr the kinetic energy will be -

= (80/16)^2

= (5)^2

= 25 times more.

Thus, the correct answer would be - 25 times.

Answer 2

1. According to Model 1, in what type of organs are the cells that enter meiosis I found? 2. Considering what you already know about mitosis in cells, what event must take place during interphase before a cell proceeds to division? 3. What two structures make up a single replicated chromosome? 4. In Model 1, how many replicated chromosomes does the cell contain during prophase? 5. At which stage in meiosis I do the pairs of homologous chromosomes come together? 6. Once the chromosomes have formed a pair, what are they called?​

Answers

Answer:

1.) Sex organs

2.) DNA replication

3.) Sister chromatids

4.) Two identical daughter cells

5.) Late prophase 1

6.) Tetrads

Explanation:

Meiosis is a type of cell division that occurs in living organisms which involves the division of a single cell to produce four cells containing half the original amount of the parent genetic information. An example of organs that enter meiosis is the SEX CELLS.

Mitosis is another type of cell division that leads to the production of two daughter cells which are genetically identical to the parent cell. During interphase before a cell proceeds to division, DNA replication must occur. This is a process DNA uses to make a copy of itself during cell division.

Chromosomes are genetic material which occurs in pairs known as the SISTER CHROMATIDS

PROPHASE in the stage the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells

During late prophase 1 the pairs of homologous chromosomes come together to form two chromosomes and four chromatids, with one chromosome originating from each parent.

Once the chromosomes have formed a pair they are called TETRADS

many of the deeper layers there are
consistently large animal skulls but
there is a sudden shift in the skull size in

suggest?

Answers

This suggests that sudden change that occur to the environment cause a different size animal to become the main species of that area.

Why the fossils of small skull organisms were found?

This is because at that particular environment the small skull organisms can survive at that time as compared to big skull animals. The presence of a specific type of fossil in the soil layer shows that the fossil organism live at that time on this area due to the presence of good environmental conditions so we can conclude that environment was good for the small skull organisms at that time.

Explain how the fossil described above supports the idea of plate tectonics?

Answers

Answer:

Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together.

This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.

Fossils tell us when and where plants and animals once existed. Some life "rode" on diverging plates, became isolated, and evolved into new species. Other life dispersed to new areas as continents reconnected, oceans narrowed, or chains of volcanic islands formed. Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.

Describe one density dependent factor and how it affects a population

Answers

Let's start off with an example. Imagine a population of organisms—let's say, deer—with access to a fixed, constant amount of food. When the population is small, the limited amount of food will be plenty for everyone. But, when the population gets large enough, the limited amount of food may no longer be sufficient, leading to competition among the deer. Because of the competition, some deer may die of starvation or fail to have offspring, decreasing the per capita—per individual—growth rate and causing population size to plateau or shrink.
In this scenario, competition for food is a density-dependent limiting factor. In general, we define density-dependent limiting factors as factors that affect the per capita growth rate of a population differently depending on how dense the population already is. Most density-dependent factors make the per capita growth rate go down as the population increases. This is an example of negative feedback that limits population growth.
