In addition to mutations, genetic variation can also arise during the formation of gametes during meiosis. During meiosis I, homologous chromosomes can randomly exchange segments, in a process called crossing-over. This trading changes the order of the genes in the DNA and on the chromosomes. Exchange material is integrated into the rest of the chromosomes DNA. Each chromosome loses some DNA and gains some DNA. As a result, there are more genotypes in the offspring. 2. What function does recombination by crossing-over have in genetic variation

Answers

Answer 1

Answer:

Crossing over ensures that organisms of the same parents have differences in genetic content making them unique in one way or the other.

Explanation:

This question is describing the process of crossing over, which occurs only during prophase I of meiosis. During the process of crossing over, alleles of a gene are exchanged between non-sister chromatids of homologous chromosomes (mother and father chromosomes).

Hence, a unique GAMETE that has been genetically recombined will be formed. When these gametes are fertilized (egg) or fertilizes (sperm), organisms that are genetically different from their parents are produced. This ensures genetic variation, which is a difference in the genetic content of organisms.

Explain how carbon cycles through the ecosystem in which you live.

PLEAASE HELP :((

Answers

Answer:Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

Refers to the broader range of changes such as the changes in average weather patterns in an area overtime

Answers

Answer:

Climate.

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time.

The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

On the other hand, climate can be defined as the change in the atmospheric conditions and manifestation of weather in a particular area over a long period of time usually 30 years.

Hence, climate refers to the broader range of changes such as the changes in average weather patterns in an area overtime.

For this assignment, you will develop a scientific model on a poster that illustrates the role of
photosynthesis and cellular respiration in the carbon cycle. Your model should also show how carbon
cycles the Earth’s four spheres. Once you have completed your model, you will write a paper with several
paragraphs describing the content of your model in more detail.

Answers

Answer:

The model has carbon in lithosphere, hydrosphere, biosphere, and atmosphere in different forms.

Explanation:

In the model, carbon is present in the atmosphere in the form of carbondioxide gas. This carbon is absorbed by the plants in the process of photosynthesis in order to produce food for itself and other organisms while on the other hand, plants, animals and humans give this carbondioxide to the atmosphere through the process of respiration. Carbon is present in earth spheres such as lithosphere, hydrosphere, biosphere, and atmosphere. Carbon is present in the land in the form of coal, oil, and natural gas, oil shale, and limestone. It is also present in water in dissolve form. It is present in the body of plants and animals in the form of proteins, fats and carbohydrates. It is present in the atmosphere in the form of carbondioxide gas.

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).

Answers

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.

The answer is I believe is c

The statement 'natural selection is one mechanism of evolution' is CORRECT (Option C).

Evolution refers to the modification of inherited phenotypic traits in successive generations as a consequence of the adaptation to specific environmental conditions.

Natural selection is considered the main force driving evolution.

This mechanism (natural selection) increases the frequency of adaptive genes and/or alleles across generations by differential survival and reproduction of organisms better adapted to the environments in which they live.

In conclusion, the statement 'natural selection is one mechanism of evolution' is CORRECT (Option C).
