Answer:

A limiting factor is a situation or condition that determines the speed or growth of a certain biological or social process, due to the fact that only a limited amount of it is available.

Therefore, a limiting factor is one that places a limit on the development of a certain characteristic within society. A clear example within biology is the lack of drinking water sources, which is a limiting factor for the development of population settlements, as occurs in the Sahara.

Thus, the existence of limiting factors puts a brake on the unrestricted development of human society, conditioning its development to the adaptation of individuals to the natural conditions of the environment.

Possible Answer:

Human society makes modifications to the environment to suit its needs. Humans can live in large numbers in harsh environments that do not necessarily support the population because of these modifications. Humans cannot, however, change the fact that they are affected by limiting factors. They can change the limiting factors in a specific area, but are still influenced by limiting factors in a larger area, either by region, or globally. Food, water, and energy supplies are limited and will only support a certain human population size. If the human population exceeds this size than disease, famine, and other limiting factors will naturally limit the population size.

The population's gene pool, the frequency of the B allele is 0.7 (or 70%) and the frequency of the b allele is 0.3 (or 30%).

To calculate the frequencies of the two alleles (B and b) in the population's gene pool, we can use the allele frequency formula. The allele frequency is the proportion of a specific allele within a population.

Given the genotypes BB = 30, Bb = 10, and bb = 10, we can determine the number of alleles in the population as follows:

Number of B alleles = 2 * (number of BB genotypes) + (number of Bb genotypes)

= 2 * 30 + 10

= 60 + 10

= 70

Number of b alleles = 2 * (number of bb genotypes) + (number of Bb genotypes)

= 2 * 10 + 10

= 20 + 10

= 30

Next, we can calculate the frequencies of the two alleles:

Frequency of B allele = (Number of B alleles) / (Total number of alleles)

= 70 / (70 + 30)

= 70 / 100

= 0.7

Frequency of b allele = (Number of b alleles) / (Total number of alleles)

= 30 / (70 + 30)

= 30 / 100

= 0.3

Meiosis I contributes in genetic variation due to the event of crossing over. On the other hand, Meiosis II results in the formation of four daughter cells that are genetically different.

Meiosis is the process of cell division that changes the ploidy of the parent into half in the daughter cells. It is accomplished in two phases: Meiosis I and Meiosis II. Meiosis I is the reductional division where the actual ploidy is changes whereas Meiosis II is the equational division that leads to the formation of four different daughter cells.

Crossing over is an event that occurs in Prophase I of Meiosis. It is the process of exchange of genetic material between the two homologous chromosomes, one from the father while another from the mother.

No, "Crick and Watson" is not a type of genetic test. Crick and Watson refer to James D. Watson and Francis Crick, who were scientists involved in the discovery of the structure of DNA. They proposed the double-helix structure of DNA in 1953, which provided the foundation for understanding genetic information and its role in heredity.

Genetic tests, on the other hand, are laboratory tests that analyze an individual's DNA or genes to provide information about their genetic makeup, potential genetic disorders, or predispositions to certain conditions.

These tests can be used for various purposes, such as diagnosing genetic disorders, predicting the risk of developing certain diseases, determining carrier status for genetic conditions, or providing ancestry and genealogical information.

While Crick and Watson made significant contributions to the field of genetics, they are not directly associated with genetic testing. Genetic tests are based on scientific advancements and technologies developed after their groundbreaking discovery of the DNA structure.

Answer:

SEXUAL REPRODUCTION:

-creates genetically unique offspring

-organism needs time to reach adulthood to reproduce

-requires the contribution of two parents

ASEXUAL REPRODUCTION:

-creates genetically identical offspring

-organism doesn’t have to waste energy to find a mate

-requires the contribution of a single parent

Explanation:

Living organisms employ two types of reproduction to produce their offsprings. They are sexual reproduction and asexual reproduction.

Sexual reproduction is that reproduction involving the fusion of two sex cells from opposite sex individuals i.e. male and female. Sexual reproduction forms offsprings with unique genetic contents, which is as result of the meiotic process that each individual organism undergoes to produce gametes or sex cells (sperm and eggs). Since there must be a fusion of gametic cells, sexual reproduction requires the contribution of two parents (a male and a female). Also, the parents only undergo meiosis to produce gametes at certain points in their life. Hence, they have to wait to reach adulthood to do that.

On the other hand, asexual reproduction involves only the contribution of one parent as the fusion of genetic material is not needed. Hence, the offsprings form by cellular division that makes it genetically identical to the parent cell. Energy is not needed to find a mate, the organism simply reproduces on its own by dividing into daughter cells.

The graph on the left demonstrates how environmental heavy metal content rises when both coal use and the human population rise. This is because burning coal releases pollutants, some of which contain heavy metals including lead, mercury, and arsenic.

These pollutants are discharged into the environment as the population rises and more coal is burned, which raises the levels of heavy metals in the environment.

The right-hand graph illustrates how biodiversity varies under the same circumstances. Biodiversity declines when the human population rises and coal use rises. This is due to the potential harmful effects of the pollutants emitted by burning coal on the ecosystem, which might result in a reduction in the number of species that can thrive in that habitat.

The Cellular Respiration worksheet is given in the image attached.

Cellular respiration is seen as a metabolic process that occurs in cells, where organic molecules are broken down to release energy in the form of ATP (adenosine triphosphate).

This process involves three main stages: glycolysis, the Krebs cycle, and oxidative phosphorylation. During glycolysis, glucose is broken down into pyruvate, which then enters the Krebs cycle, where it is further broken down to release energy-rich electrons.

Therefore, These electrons are then passed down a series of electron transport chains to produce ATP through oxidative phosphorylation. Cellular respiration is a vital process for all living organisms, as it provides the energy needed for various cellular processes and activities.

This type of learned response is called conditioning, the baby will expect

The offspring resulting from pollinating a flower of one plant with the scraped-off flower of another plant will be genetically distinct from their parent (option c) .

When a botanist scrapes off a flower from one plant, it collects the pollen from that flower.

The botanist then uses the collected pollen to pollinate the flower of another plant, transferring the genetic material from one plant to another.

Pollination is the process by which pollen grains are transferred from the male reproductive organ (stamen) to the female reproductive organ (pistil) of a flower.

During pollination, the pollen carries the genetic information (DNA) of the plant it came from.

When the pollen reaches the stigma of the second plant's flower, it fertilizes the ovules and initiates the formation of seeds.

The seeds that develop from this cross-pollination will contain a combination of genetic material from both parent plants.

Due to the mixing of genetic material, the offspring will be genetically distinct from either parent.

The specific characteristics of the offspring will depend on the traits inherited from each parent.

Genetic recombination and variation occur during sexual reproduction, resulting in offspring that exhibit a range of genetic traits.

Therefore, based on the process of sexual reproduction and genetic mixing through pollination, it can be concluded that the offspring will be genetically distinct from their parent.

This is an astronomically large number and suggests that it is highly unlikely for any two individuals to have the same DNA profile at these four loci.

DNA (Deoxyribonucleic acid) is a long, complex molecule that contains the genetic instructions used in the development and function of all known living organisms and many viruses. It is often described as the "blueprint" or "code" of life. DNA is composed of four types of nucleotides, which are the building blocks of the DNA molecule. Each nucleotide contains a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). The sequence of these bases along the DNA molecule determines the genetic information it carries.

Here,

To determine the number of individuals in the US population that have a specific DNA profile at these four loci, we need to multiply the percentage of individuals with each genotype at each loci. Let's start by finding the number of individuals in the US population who have 8 repeats at loci 1. We know that 10% of the US population has this genotype, so:

Number of individuals with 8 repeats at loci 1 = 10% of 300 million

= 0.1 x 300,000,000

= 30,000,000

Similarly, we can find the number of individuals with 12 repeats at loci 2:

Number of individuals with 12 repeats at loci 2 = 5% of 300 million

= 0.05 x 300,000,000

= 15,000,000

For loci 3:

Number of individuals with 7 repeats at loci 3 = 10% of 300 million

= 0.1 x 300,000,000

= 30,000,000

And finally, for loci 4:

Number of individuals with 5 repeats at loci 4 = 30% of 300 million

= 0.3 x 300,000,000

= 90,000,000

To find the number of individuals with all four of these genotypes, we need to multiply these four values:

Number of individuals with all four genotypes = 30,000,000 x 15,000,000 x 30,000,000 x 90,000,000

= 3.87 x 10²⁵

This is an astronomically large number and suggests that it is highly unlikely for any two individuals to have the same DNA profile at these four loci. In practice, forensic DNA profiling typically looks at many more loci to increase the uniqueness of the DNA profile.
