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.

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.

Which of the following is a correct statement about the relationship between natural selection and evolution?
(3 points)
A. Natural selection results from evolution.
B. Natural selection includes evolution as a part of it.
C. Natural selection is one mechanism of evolution.
D. Natural selection and evolution are the same thing.

Answers

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).

Why do you think Leeuwenhoek named the cells he observed "animalcules"

Answers

Answer:

Using single-lensed microscopes of his own design and make, Van Leeuwenhoek was the first to observe and to experiment with microbes, which he originally referred to as dierkens, diertgens or diertjes (Dutch for "small animals" [translated into English as animalcules, from Latin animalculum = "tiny animal"]).

Leeuwenhoek named the cells he observed originally as dierkens, which is the Dutch word for small animals, and translated to English as animalcules.

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.

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.
