Question:
Chromosomes are distributed randomly during anaphase I. What are the possible chromosome combinations in the two daughter cells? (Use the following abbreviations for the chromosomes. Dark green -> DG; Light green -> LG; Dark purple-> DP, Light purple -> LP)
How does the random lining up of the homologous chromosome in Metaphase 1 contribute to Genetic Variation?
Answer:
Possible chromosome combinations:
LG,LP + DG,DP LG,DP + DG,LPThe random arrangement of tetrads is different in every cell going through the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is different and depends on the chromosomes that form that cell.
Explanation:
1) During meiosis, organisms can produce at least four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.
The possible chromosome combinations in the two daughter cells of the exposed example are
LG,LP + DG,DP LG,DP + DG,LP2) Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
Possible chromosome combinations:
LG,LP + DG,DP LG,DP + DG,LP
The random arrangement of tetrads is different in every cell browsing the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it.
Anaphase I
Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the amount of variations in each cell is different and depends on the chromosomes that form that cell.
During meiosis, organisms can produce a minimum of four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.
The possible chromosome combinations within the two daughter cells of the exposed example are-
LG,LP + DG,DP LG,DP + DG,LP
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
Metaphase I
During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles.
The random arrangement of tetrads is different in every cell browsing the meiosis process. There is no equal alinement between the two cells.
When tetrads aline within the equatorial plane, there's no predetermined order for every one of the homologous chromosomes of every tetrad to face one among the poles then migrate to it while separating.
Any chromosome of the homologous pair might face any of the poles then migrate thereto. Each of the chromosomes has two possibilities for orientation at the plane.
When the new haploid cells are formed, the amount of variations in each cell is additionally different and depends on the chromosomes that form that cell.
This random order within the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get an equivalent genetic charge.
Therefore,the combinations of two daughter cells LG,LP + DG,DP and LG,DP + DG,LP.

What is the greenhouse effect?
Explanation:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

Explanation:
Had the same question on a test. Hope this helps :)
DNA is a genetic material found in every living organism. DNA is made up of purines, pyrimidines, a pentose sugar, and phosphate backbone. DNA is a genetic material that carries information from parent to daughter cells.
The correct answer is:
Option A. Nucleotide bases in one strand can only be paired with specific bases in the other strand.
Characteristics of the DNA include:
1. DNA is a double-stranded genetic material, which is made up of four nitrogenous bases, adenine, cytosine, thymine, and guanine.
2. These nucleotides bind to specific nucleotide sequences present on the template strand of the DNA.
3. DNA consists of coded sequences known as genes, which are inherited from the parent to the daughter cells.
4. DNA undergoes a unique semi-conservative mode of replication.
Thus, the correct answer is the ability of the DNA nucleotides to bind to the specific bases in the other strand.

Think of another science topic you studied earlier. How might considering scale be useful when investigating that topic? How is that similar to and different from how the crosscutting concept of Scale is useful in this unit?
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 populationsIn 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.

What % of energy does plants receive from the sun
Answer:
Most solar energy occurs at wavelengths unsuitable for photosynthesis. Between 98 and 99 percent of solar energy reaching Earth is reflected from leaves and other surfaces and absorbed by other molecules, which convert it to heat. Thus, only 1 to 2 percent is available to be captured by plants.

Which example best represents the results of mitosis?

O
B. Four siblings' cells are identical to their parents' cells.
O
C. Four bacteria daughter cells are similar to their parent cell.
OD. Four bacteria daughter cells are identical to their parent cell.
Answer:
A. Four siblings' cells are similar to their parents' cells.
Explanation:
Genetics of offspring are based on the paten but it will never be identical to them. The reason why is when the male and female cells combine to form a child they mix and most of the time one will dominate the other. You can have cases where you have both alleles though. Sometimes they also mix to form a new one. But usually you'll get one from each parent.
