How does genetic variation create diversity?

Answers

Answer 1
Variation allows some individuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation.

Discuss which type of reproduction is the "best" strategy for continuing a species through time in a changing environment and justify your answer.

Answers

Answer:

Any sort of sexural reproduction.

Explanation:

Unlike asexual reproduction, sexual reproduction allows the species being produced to adapt the the changing environment around it to increase the chances of survival. For asexual reproduction, clones are made of the parent and, therefore, cannot withstand any extreme conditions that the parent species couldn't. For a changing environment, sexual is the best to allow the specimen and its offspring to change positively along with the environment.

The diagram shows a model of a section of double-stranded DNA. The straight lines and dotted lines represent chemical bonds between the
components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.

Answers

During DNA replication, the hydrogen bonds must be broken between the complementary nitrogenous bases in the DNA double helix. Hope this helps! Maybe mark me the brainliest??

The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

What role does DNA replication play?

DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.

Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

In osmosis molecules move through a semi-permeable membrane from a high concentration to a low concentration. True or False​

Osmosis is the movement of water molecules through a selectively permeable membrane from high to low concentrations.  

Diffusion is the process in which molecules move from an area of high concentration to low concentration.

What needs to happen for natural selection to occur? Highlight all that apply.
A. Some of the traits will provide individuals an advantage over others.
B. Some variation occurs in the inherited traits.
C. A natural disaster.
D. Individuals with certain traits are more likely to have an increased number of offspring

Answers

Answer:

A

Explanation:

Natural selection occurs because those with more favorable traits survive while the others don't. If there are no favorable traits in a community then there is no natural selection.

Some organisms, such as fish and mosquitoes, produce very large numbers of offspring. Why is producing a large number of offspring important for natural selection?

10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.

Answers

6. Is false because the factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy.

7. Is true because Solar energy is created when it is used in the process of photosynthesis in a plant. Then chemical energy is used when the plants create glucose.

8. Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory. Arrow F shows respiration and carbon being released.

9. The cycle would be made by process C and E. The process E happen when the organism dies and become a fossil. The organism could be a cow that eats grass(plants) that takes carbon from the atmosphere by doing photosynthesis.
The process in C happens when the factory (nonliving) using fossil fuel and produce carbon. The factory takes the fossil, use it as fuel, and return the carbon to the atmosphere.

10. The process of photosynthesis and cellular respiration can represent the law of conservation of mass and energy. In photosynthesis, you need sunlight(arrow A), carbon dioxide(arrow B) and water. The process will produce glucose which can be used in cellular respiration.
In cellular respiration, the glucose will produce energy which was made from sunlight. It will also produce water and carbon dioxide that will be released back into the atmosphere (arrow F)

Answers

Scale can be extremely important to consider when applying the conclusions of an investigation to a larger group.

Scale is defined as a series of measurements in a given ratio, in order to compare two objects or groups. Some examples include:

Scale modelsScale populations

In the case of scale models, one example may be creating a 1:100 scale model of a building. What this means is that the model created will be one hundred times smaller than the original.

The idea of scale is very important to consider when performing experiments. For example, if we were to take a sample of 10 people and test for a specific bacteria, which gives us a result of 1 in 10 (or 10%) of the people that test positive for the bacteria, it would seem as though it is a very small number of people. However, if we take scale into consideration we can apply this 10% to the global population, which will result in hundreds of millions of people who will test positive for the bacteria.

Scale is important to consider when performing any experiment or drawing conclusions because it offers a method to calculate and make an educated assumption as to the impact of the results on a population that would otherwise be impossible to test.

Soil has vital nutrients for plants. As a result, it is used in agriculture to nourish plants. The roots of a plant receive nutrients from the soil to help it grow. The North Carolina Department of Agriculture and Consumer Services notes that 13 essential plant nutrients come from the soil.

Building

Soil is an important part of the building process. Soil compaction, which increases the density of the soil, is done as part of the building process. The purpose of the compaction is to improve the load support. If not done, structural failure can result. Soil can also be used as building materials such as adobe and red bricks.

Answers

Answer:

d. Views could be used to make topographic maps of the area.

Explanation:

Satellite views helps the planners in choosing  a location for the airport because it provides topographic maps of the area which contains all information about natural features of that area such as roads, railways, power transmission lines, contours, elevations, rivers and lakes. So the satellite images provides a great help to the planners to find out suitable place for the airport.
