The combined genetic information of a population forms a.

Answers

Answer 1

The combined genetic information of a population forms a gene pool. What is a gene pool The entire genetic  or the genetic makeup present within a population is known as a gene pool. This gene pool consists of all the genes and their different alleles present within a population

 The gene pool can also be defined as the sum total of all the genes and alleles present in a particular population or a community to the given question is, "gene pool. This pool of genes is what enables evolution. This is because in evolution, genetic variation is the primary raw material that acts as a driving force. Genetic variation can either be caused by mutations or by genetic recombination. Gene pool acts as a reservoir for all the different genetic traits that can either be dominant, recessive or have intermediate expression.

In addition to The gene pool provides genetic diversity that enables the population to adapt to changes in the environment, or to colonize new habitats with different selective pressures. The gene pool is important because it determines the ability of a population to adapt and evolve to changing environmental conditions.Thus, the gene pool is the source of genetic variation that is essential for the evolutionary process. Without genetic variation, there would be no way for populations to adapt and evolve in response to changes in the environment.

B. a state’s decision that states could ignore laws not in the Constitution
C. the tariff of 1832 that reduced tariff rates to 35%
D. the belief that the tariff system would bring poverty to the North
E. a biased system that favored the agricultural states

Answers

Answer:

A. South Carolina’s refusal to pay taxes on goods it did not produce

B. a state’s decision that states could ignore laws not in the Constitution

Explanation:

A state's decision which states could ignore laws not in the Constitution caused the Nullification Crisis in 1832. Therefore, the correct option is B.

South Carolina's assertion of state power to overturn federal law was deemed unconstitutional, leading to the Nullification Crisis of 1832. South Carolina particularly opposed the tariffs of 1828 and 1832 because they were considered harmful to its economy.

They claimed that if the states felt that federal laws were illegal, they had the right to nullify them within their own borders. The concept of "disempowerment" raised questions about the legitimacy of the federal government and how the states and the federal government should interact.

Therefore, the correct option is B.

Answers

Individual a has the higher fitness because more of its offspring survived compared to the original amount of offspring

In natural selection when more offspring is survived is a sign of higher fitness of the particular population, hence given statement is true.

What is natural selection?

Most qualities are inherited, there are more children generated than can survive, and offspring with more advantageous features will survive and have more offspring than those with less advantageous traits leading to the inevitable process of natural selection.

Since there are only so many resources available, more creatures are born than can live those who are better at obtaining food.

Mating or evading predators will have a higher chance of thriving, procreating, and passing on their DNA.

a study that looked at the addition of nitrogen, in the form of nitrates and ammonium, to terrestrial north american communities found that all sites increased in primary productivity yet some sites saw a decline in species diversity. what is the most likely explanation of why this decline in species diversity was observed?

Answers

The most likely explanation for the decline in species diversity observed in the study is that the addition of nitrogen, in the form of nitrates and ammonium, led to increased primary productivity, favoring certain plant species that can efficiently utilize the added nutrients.

The most likely explanation for the decline in species diversity observed in some sites after the addition of nitrogen (nitrates and ammonium) could be attributed to increased competition among species. Nitrogen fertilization can enhance primary productivity, leading to resource availability and favoring certain fast-growing species over others. This competitive advantage may result in the exclusion or reduced abundance of less competitive species, thereby reducing overall species diversity in those particular sites.

Answers

A unicellular organism is a living organism that consists of a single cell. This means that all of the functions necessary for life, including reproduction, metabolism, and responding to the environment, are carried out by a single cell.

Two examples of unicellular organisms are:

1. Bacteria - these are single-celled organisms that are found in many different environments, including soil, water, and the human body. Some bacteria are beneficial, while others can cause disease.

2. Protozoa - these are single-celled organisms that are typically found in aquatic environments. Some protozoa are parasites and can cause diseases like malaria.

In contrast, a multicellular organism is a living organism that is made up of multiple cells that work together to carry out the functions necessary for life. This allows for greater complexity and specialization in different parts of the organism.

Two examples of multicellular organisms are:

1. Humans - humans are complex organisms made up of many different types of cells, including muscle cells, nerve cells, and blood cells. Each type of cell has a specialized function that contributes to the overall functioning of the organism.

2. Trees - trees are also multicellular organisms that are made up of many different types of cells, including those that make up the trunk, branches, and leaves. Each type of cell has a specialized function that helps the tree grow, produce fruit, and carry out other important activities.

Answer:

Explanation:

how many different kinds of genotypes are possible among offspring produced by the following two parents? assume complete dominance and independent assortment. ffgghh x ffgghh

Answers

The offspring produced by the two parents with genotypes ffgghh and ffgghh can have a total of 64 different genotypes.

To determine the number of different genotypes, we need to consider the independent assortment of alleles and the concept of complete dominance.

The parents have genotypes ffgghh and ffgghh. Each letter represents an allele at a specific gene locus, and lowercase letters indicate that they are recessive alleles. The uppercase letters represent dominant alleles.

For each parent, there are three gene loci with two alleles each, resulting in 2^3 = 8 possible genotypes. When we cross the two parents, we can consider each gene locus independently.

At each gene locus, the dominant allele will be expressed, and the recessive allele will be masked. Since both parents have the same genotype at each locus, all offspring will have the same dominant alleles.

Therefore, we don't need to consider the dominant alleles while calculating the number of genotypes.

For each gene locus, the offspring can inherit either the recessive allele from the first parent or the recessive allele from the second parent. With three independent gene loci, we have 2^3 = 8 possible combinations for the recessive alleles.

By multiplying the number of possible recessive allele combinations for each gene locus, we get the total number of different genotypes: 2^3 * 2^3 * 2^3 = 8 * 8 * 8 = 64.

Therefore, the offspring produced by the two parents can have a total of 64 different genotypes.

How do scientists plan to use copy number variants and identical twins to determine the roots of diseases? In your response, use the words: gene

Answers

Identical genes have the same genetic material and the same genes. So if they both have a disease it's likely that it's genetic.

Scientists plan to use copy number variants (CNVs) and identical twins to determine the genetic differences between them and the cause of genetic disease as CNVs are variations in the copies of a gene in an individual's genome.

What is the significance of copy number variants?

Scientists use copy number variants (CNVs) to study the genetic diseases in twins and CNVs are variations in the copies of a gene in an individual's genome, but in identical twins, they have the same genetic makeup. By analyzing the CNVs in twins, scientists can identify the genes that may be involved in the disease and how they contribute to its development.

The Devil facial tumor disease (DFTD) is an infectious,  cell-cycle disease

Diseases are abnormal conditions that negatively affects the structure and function of all or parts of a living organism and which is not usually caused by an immediate injury.

Diseases can be infectious or non-infectious based on their mode of transmission.

Infectious diseases can be transmitted from one infected organism to another whereas, non-infectious diseases are not transmitted from one infected organism to another.

Disease can also be chronic or acute based on the nature and duration.

Acute diseases occur suddenly and produce rapidly developing symptoms which do not last for long

Chronic diseases on the other hand takes a longer time to develop and its symptoms worsen with time.

Cell-cycle diseases are diseases caused by unregulated cycles of cells involving cell growth and cell death. Cancer is the most common disease caused by unregulated cell growth.

The Devil facial tumor disease (DFTD) is an infectious disease since it passes from one animal to another through bites and is caused by parasites.
