Show the importance of the inheritance of how steps in meiosis change chromosomes through one of these processes.
Background: Meiosis is the process used by sexually reproducing organisms and is made up of eight sub-steps or phases. During meiosis, chromosomes can be changed through crossing over and nondisjunction leading to changes in the inherited traits of offspring.
Meiosis is the process that occurs in sexually reproducing organisms in the sex cells of male and female organisms.
Variation occurs in an organism due to the process of crossing over which only occurs in meiosis in which the chromosomes between non-sister chromatids exchanged. Meiosis also causes genetic variation due to the process of recombination so in inheritance, meiosis has great importance and impact on the shape and structure of organism.

In CaF2, the oxidation number of Ca is , and that of F is . In H2SO4, the oxidation number of H is , that of S is , and that of O is . In CaSO4, the oxidation number of Ca is , that of S is , and that of O is . In HF, the oxidation number of H is , and that of F is
Answer:
1. The oxidation number of Ca is 2, F is -1 in CaF₂
2. The oxidation number of H is 2, S is 6, O is -8 in H₂SO₄
3. The oxidation number of Ca is 2, S is 6, O is -8 in CaSO₄
4. The oxidation number of H is 1, F is -1 in HF
Explanation:
To get the oxidation number, we need to take the oxidation number of the whole compound 0. Then we need to know the oxidation number of the other elements and we need to take 'x' as the oxidation number of the unknown element.
Example:
In case of CaSO₄,
We can write an equation as-
CaSO₄ = 0
If we need to know the oxidation number of S
We can write the equation like this-
→2+ x+ (-2*4) = 0 (as we know the oxidation number of Ca is 2 as it has two electrons in its last shell which it gives to other elements to form bonds and the oxidation number of O is -2 as it takes 2 electrons to complete its outer shell)
→2+ x+ (-8) = 0
→2+ x- 8 = 0
→x- 6 = 0
→x = 6; which is the oxidation number of S
The following are the oxidation numbers:
In CaF2, the oxidation number of Ca is +2, and that of F is -1.
In H2SO4, the oxidation number of H is +1, that of S is +6, and that of O is -2.
In CaSO4, the oxidation number of Ca is +2, that of S is +6, and that of O is -2.
In HF, the oxidation number of H is +1, and that of F is -1.
What is oxidation number?Oxidation numbers are a way of representing the degree of oxidation (loss of electrons) or reduction (gain of electrons) of an element in a chemical compound. The oxidation number of an element is calculated based on the number of valence electrons (electrons in the outermost energy level of an atom) and the rules for assigning oxidation numbers.
In general, the oxidation number of an element is equal to the charge it would have if all the bonds in the compound were ionic (made up of positive and negative ions). This allows chemists to predict the behavior of elements in a compound and to balance chemical equations.

Significant amounts of phosphorus are found in all locations on Earth except the..
Answer:
Atmosphere
Explanation:
Phosphorus cycle in nature is a unique cycle compared to the other natural biological and chemical cycles such as the carbon, nitrogen, sulfur and water cycles, as there is no gaseous phase in the phosphorous cycle. Due to the prevailing atmospheric temperature and pressure which are not appropriate for the formation of gases associated with phosphorus, the compounds in nature where phosphorus can be found are not gases. Phosphorus can therefore be found majorly in sedimentary rocks.
The atmospheric temperature and pressure are incapable of forming phosphorus compounds, Phosphorus has not been found in the atmosphere.
Phosphorus has been the recycled in the atmosphere within the biosphere, lithosphere, and hydrosphere. In the nature, the phosphorus has been present in the sedimentary rocks, with the absorption by plants and animals.
The phosphorus cycle has been consisted of the weathering, absorption by plants and animals and return to the lithosphere with the decomposition. Since the atmospheric temperature and pressure are incapable of forming phosphorus compounds, Phosphorus has not been found in the atmosphere.

In the past few decades, the number of polar bears in the Arctic region has dropped considerably. How might humans help to save these species?
Answer:
c.
Explanation:
Breed Polar bears in captivity , and then release them in the colder areas.
The colder the area the less of a chance there would be for the ice to melt fast enough sweeping away the bears shelter.
Climate change is the long-term alteration in weather patterns. It impacts the polar bears of the arctic region that can be saved by breeding them in captivity and then releasing them into their natural habitat.
What is the impact of climate change?Climate change is the pattern of the disturbance in the weather and the temperature condition of the earth and its various places. It is a result of increased global warming caused by pollution.
Climate change affects the oceans and sea by raising their temperature leading to the melting of the ice caps and glaciers. This results in habitat destruction and decreases the population of arctic animals like polar bears.
To increase the population of polar bears, humans can breed them in an artificial environment and then can release them into their natural habitat like the colder places.
Therefore, the population can be increased by breeding.

If everyone on the planet used the same amount of resources as an average American, what percent of the Earth would
need to be used to support everyone?
A. 75%
B. 50%
C. 150%
D. 200%
Answer:
D. 200%
Explanation:
While Americans constitute the 5% of the world population, they use around the 24% of the world's energy.
Then, if the 100% of the population were like the Americans, we have:
5%*x = 100%
x = 100%/5% = 20
the whole population is 20 times the population of the US, then the total energy used is 20 times the energy used in the US.
Then the energy that the 100% of the population would use is equal to:
20*24% = 480%
So we actually would need like 5 Earths.
The option is 200%

In the autumn, many birds will collect seeds and then hide them in various caches throughout their habitat. The birds will guard their caches from other birds, and move the caches if they start to dry out. These caches provide a food source for the birds during the winter. What is an abiotic factor that contributed to the evolution of this set of behaviors? A. being preyed upon by larger birds B. competition with other birds for space C. limited food availability D. cold winter climate
Answer:cold winter climate
Explanation:During winter specially in the eastern and western part of the world....snows bury grounds and food that enables this organisms live....and cold can also affect them
Answer:
Answer: c. limited food availability
Explanation:
Both biotic and abiotic factors are responsible for shaping the evolutionary framework of the population. Resource availability can be one of the important abiotic factor in determining the evolutionary dynamics of the population or species. Limitations in resource can result in increase in competition. According to population exclusion principle when two species compete for the same limiting resource this results in co-evolution of both the species. But the extent of evolution may vary among the species. The one which undergoes more favorable evolution will be stronger competitor and drive more resources and will be fit for survival in adverse limiting conditions.
A student places a healthy potted plant and a plastic straw in a closet for two weeks. After two weeks, the student observes that the plant is wilted and brown, while the plastic straw remains the same. The student classifies the plant as living and the plastic straw as nonliving.
What criteria does the student use to classify the plant as living rather than nonliving?
Answer:
Plants need water and sun to create their food source, glucose. When the plant was left in the closet it didn't have access to the sun. One of the requirements of life is that all living things need energy/have a metabolism. Without food the plant eventually died.

Algae in the genus Caulerpa typically grow to a length of over half a meter and have structures similar to stems,leaves,and roots.Reproduction occurs when adults produce sperm and eggs that fuse to form offspring.Each adult Caulerpa consists of just a single cell,however.Which of the following statements is true?
A) Caulerpa violate the pattern component of the cell theory that all organisms consist of cells.
B) Caulerpa violate the process component of the cell theory that all cells come from preexisting cells.
C) Caulerpa violate both the pattern and process components of the cell theory.
D) The existence of Caulerpa is consistent with the cell theory.
Answer:
D) The existence of Caulerpa is consistent with the cell theory.
Explanation:
This question describes species of algae in the genus, Caulerpa, which is a unicellular organism that possesses structures similar to leaves, stems and roots in plants. It also grows to a length of about 0.5metres. it reproduces sexually by fertilization of gametes (sperm and egg).
According to all these described characteristics of Caulerpa, it's existence is in conformity or accordance with the unified cell theory, which was proposed by three scientists namely: Matthias Scleiden, Theodor Schwann, and Rudolf Virchow in the 1830's. The three components of the cell theory states that:
1. Cell is the fundamental and basic unit of life existence.
2. All living organisms are composed of one (unicellular) or more cells (multicellular).
3. All cells come from already preexisting cells.
Hence, based on the components of the cell theory and the life pattern of Caulerpa i.e. Caulerpa is made up of one cell, it is made from the fusion of preexisting parental cells etc. It is consistent with the cell theory.

What is chromosomes?Write in brief about the structure of a chromosome.must include all points with explanations
Answer:
Please find the detailed explanation below
Explanation:
A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.
Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.
What process is similar in function to genetic engineering but different in the mechanism it uses? A. Replication in a bioreactor B. Cellular Respiration C. Breeding for specific traits D. Genetic Calculus
Option C. Breeding for specific traits is a similar process in function to genetic engineering but different in the mechanism it uses.
Genetic engineering refers to the process of using recombinant DNA methodologies to alter the genome of a particular organism and thus obtain the desired characteristics/traits in organisms derived from them. An example of genetic engineering is the use of recombinant DNA methodologies to develop Escherichia coli strains that generate human insulin.Moreover, selective breeding refers to the process aimed at developing organisms with desirable characteristics by choosing parents with these traits in order to cross them and produce offspring with these phenotypic traits.For example, wheat plants with better yields can be obtained by crossing between wheat varieties that exhibit desired phenotypic traits.In conclusion, Option C. Breeding for specific traits has a similar objective that genetic engineering but the mechanism to reach this objective is different.Learn more in:

Answer:
solid
Explanation:
The two models explained are most closely representing the "solid" state.
As in both the models the techniques used are to separate particles through shaking technique and shaking is efficient gravity separation method which helps in separating solid particles such as while dealing with tungsten and tin.
Hence, the correct answer is "Solid".
Answer:
When the container was half full, the particles had more freedom to move around than they did when the container was full. A half-full container represents a liquid. When the container had only a few particles, they had lot more freedom to move about. So, this model represented a gas.
