Diploid organisms is used to describe an organism that has two identical alleles for a trait both alleles either upper case or lower case .

Each chromosome in diploid cells has two identical copies, typically one from the mother and one from the father. Mammals are nearly all diploid organisms. The only known exceptions are the presumed tetraploid (having four chromosomal sets) plains viscacha rat and golden viscacha rat (as of 2004).

The huge genome sizes of these two rodents are best explained by the amplification and dispersion of repetitive sequences, according to some genetic studies, which reject any possibility of polyploidy in mammals as implausible. A small percentage of the cells in all healthy diploid individuals show polyploidy. 46 chromosomes can be found in human diploid cells.

Answer:

The metabolic pathway you described involves a series of chemical reactions that convert one substrate into the next substrate until the final product is formed. If the enzyme that acts on substrate 2 is not produced within the cell, the reaction that converts substrate 1 into substrate 2 would not occur. This would cause a block in the pathway, as substrate 2 would not be available for the enzyme that converts substrate 2 into substrate 3.

Explanation:

The metabolic pathway you described involves a series of chemical reactions that convert one substrate into the next substrate until the final product is formed. If the enzyme that acts on substrate 2 is not produced within the cell, the reaction that converts substrate 1 into substrate 2 would not occur. This would cause a block in the pathway, as substrate 2 would not be available for the enzyme that converts substrate 2 into substrate 3.

As a result, the amount of product produced would be severely decreased. Because of the missing enzyme, substrate 2 would not be converted into substrate 3, and subsequently, substrate 3 would not be converted into the final product. If this key enzyme is not present, the entire metabolic pathway would be halted at the step involving substrate 2, causing the cells to be unable to produce the final product and creating a bottleneck in the metabolic pathway.

It's important to remember that enzymes are catalysts, they speed up the reactions of the metabolic pathway and ensure the reactions occur at appropriate rates to support life, even a small change in the enzyme activity can affect the entire pathway and alter the final product quantity and quality.

Relationships among organisms play a vital role in maintaining the balance and stability of ecosystems. These relationships can be categorized into three main types: mutualism, commensalism, and competition.

In mutualism, both species involved in the relationship benefit. For example, many plants have mutualistic relationships with pollinators, such as bees. The plants provide nectar as a food source for the bees, while the bees help to pollinate the plants, allowing them to reproduce.

In commensalism, one species benefits from the relationship while the other is neither helped nor harmed. The relationship between cattle and cattle egrets is an example of commensalism. The egrets feed on insects stirred up by the cattle as they graze, while the cattle are not affected by the presence of the egrets.

In competition, two or more species compete for the same limited resource. This can lead to the evolution of unique adaptations that allow a species to better exploit a particular resource, which in turn can lead to greater biodiversity in an ecosystem.

Predator-prey relationships also play an important role in ecosystems by controlling population sizes and helping to maintain balance within the ecosystem. In addition, decomposers break down dead organic matter and recycle nutrients, making them available for other organisms to use.

In summary, relationships among organisms in an ecosystem are vital for maintaining balance and stability, and ultimately ensuring the survival of the ecosystem.

A snake has scaly skin to keep from drying out in the desert. A cactus has sharp spines and a thick stem that keep water in .Adaptations term describes such traits that help organisms survive.

In biology, there are three related definitions of adaptation. First, natural selection, a dynamic evolutionary process, adapts organisms to their environments, improving their evolutionary fitness. Second, it is a state that the populace has attained along that process. Thirdly, it is a phenotypic characteristic or adaptive trait that has been preserved and has evolved via natural selection and has a functional purpose in each individual organism.

History has recorded descriptions of adaptation going back to the time of the ancient Greek philosophers Empedocles and Aristotle. Natural theology of the 18th and 19th centuries saw adaptation as proof of the presence of a deity. Charles Darwin suggested that natural selection should be used as the explanation instead.

The critical value the scientist should use for the chi-square analysis of the data is b. 3.84.

The chi-square test is a statistical test used to determine whether there is a significant difference between the observed and expected frequencies in a contingency table. In this case, the scientist is investigating whether two traits in a plant, long stems and white flowers, are determined by genes that are on the same chromosome. The scientist has conducted a genetic cross between plants that are homozygous dominant and homozygous recessive for both traits, and has obtained a sample of 100 plants in the F2 generation. The scientist has then tabulated the observed and expected frequencies of the four possible phenotypes (long stems, white flowers; short stems, red flowers; long stems, red flowers; short stems, white flowers) in the F2 generation.

The chi-square test is used to determine whether there is a significant difference between the observed and expected frequencies in the table. The calculated chi-square value is compared to a critical value from a chi-square distribution table with 3 degrees of freedom and a significance level of 0.05. The degrees of freedom for a chi-square test are equal to the number of categories in the table minus 1. In this case, there are 4 categories (phenotypes) in the table, so the degrees of freedom are 3.

The critical value for this test is 3.84. If the calculated chi-square value is less than 3.84, the scientist would conclude that there is no significant difference between the observed and expected frequencies and thus the genes independently assort, meaning that the genes are located on different chromosomes. On the other hand, if the calculated chi-square value is greater than 3.84, the scientist would conclude that there is a significant difference between the observed and expected frequencies and thus the genes are located on the same chromosome.

The surface area to volume ratio (SA:V) is a mathematical formula used to measure the relative size of a cell. It is the ratio of the surface area of a cell to its volume. Cells need to maintain a high SA:V in order to survive and function properly.

First, a high surface area to volume ratio is needed in order for the cell to take in essential nutrients and expel waste. All cells must take in oxygen, glucose, and other nutrients from the environment in order to survive, and they must also get rid of waste products such as carbon dioxide and other toxins. The surface area of a cell provides an area for the cell to access these materials, and the volume of the cell determines how much material can be moved in and out of the cell. A higher SA:V means that more of the cell's surface area is available to take in materials, and more of the cell's volume is available to expel waste.

Second, a high surface area to volume ratio is also necessary for the cell to carry out its metabolic processes. The metabolic processes of a cell require energy, which comes from the breakdown of glucose and other molecules. A higher SA:V allows for more of the cell's surface area to be used for enzyme-catalyzed reactions, and more of the cell's volume to be used for the storage and transport of molecules to and from the cell.
