There are two alleles in a population that influence a specific attribute. Using the letters "A" for the dominant allele and "a" for the recessive allele. A allele frequency is 0.7, whereas frequency of allele is 0.09.

The frequency of the A allele is 0.7, or 70%, since homozygous dominant (AA) genotypes account for 70% of the population. Similarly, since homozygous recessive (aa) alleles make up 9% of the population, we can infer that the frequency of the recessive allele, a, is 0.09, or 9%.

The formula 2pq = frequency of heterozygotes, where p is the frequency of the A allele and q is the frequency of the an allele, can be used to determine the frequency of the heterozygous genotype (Aa).

We know that the frequency of heterozygotes is 0.21, or 21%.

Plugging in the known values:

2 * 0.7 * q = 0.21

Solving for q:

q = 0.15

So, the frequency of the A allele is 0.7, and the frequency of the a allele is 0.09.

The third organism is a Shredder, which consumes algae on rocks.

The fourth organism is an Invertebrate Predator, which preys on small invertebrates.

The fifth organism is a Vertebrate Predator, which preys on vertebrates and invertebrates.

In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.

The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.

The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.

As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.

Answer:

A.) I

Explanation:

The first one is the most likely to be solid at room temperature because it is the only structure depicting a saturated fat.

Saturated fats have no double bonds between the carbons in the parent chain. This allows the molecules to assume very compact positions, causing it to be solid at room temperature.

Unsaturated fats have these double bonds which bend the structure. These "kinks" in the molecule are what make unsaturated fats liquid at room temperature.

Explanation:

Hope it helps.

DNA replication is the process by which a cell makes an exact copy of its DNA.

It is a fundamental process in all living organisms that allows for the accurate transmission of genetic information from one generation to the next. During DNA replication, the double-stranded DNA molecule unwinds and separates into two individual strands.

Each of the original strands serves as a template for the synthesis of new DNA occurs. This replication process follows a semi-conservative mechanism.

The phenomenon where a non-native species invades an ecosystem and outcompetes the native species causing the native species to decline potentially to extinction is called "invasive species.

It occurs when non-native species, also known as invasive species, establish themselves and thrive in an ecosystem, causing harm to the native species. Invasive species possess traits that give them a competitive advantage over the native species, such as rapid reproduction, efficient resource utilization, and resistance to local predators or diseases.

The consequences of biological invasions can be severe. The invasive species can outcompete native species for resources like food, habitat, and water, leading to a decline in native populations.

They may also directly predate upon or introduce diseases to native species, further exacerbating their decline. In some cases, the native species are pushed to the brink of extinction or even driven to extinction.

Biological invasions are a significant global concern due to their ecological, economic, and social impacts. They can disrupt ecosystem functioning, alter natural habitats, reduce biodiversity, and cause economic losses in industries like agriculture, forestry, and fisheries.

Efforts are made to prevent and control invasive species through monitoring, early detection, and management strategies such as eradication, containment, and control programs to mitigate their negative effects and protect native species and ecosystems.

Populations in an ecosystem can be affected by a variety of things, including habitat change, resource availability, predation, competition, disease, or human activities.

If a change occurs that adversely affects the ability to tolerate or reproduce, the amount of green leaf population may decrease. For example, if habitat is lost due to deforestation, populations of green leafhoppers may lose their preferred food supplies or nesting sites, leading to a decline in population numbers. Similarly, if predation pressure increases, a population may experience increased mortality and poor reproductive success, resulting in a decline in numbers.

A recessive gene  often does not show its trait.

option A.

A recessive gene often does not show its trait when paired with a dominant gene.

In order for a recessive trait to be expressed, an individual must inherit two copies of the recessive allele - one from each parent. If an individual only inherits one copy of the recessive allele, the dominant allele will mask the recessive trait, and the individual will not display the trait.

Option B, "overpowers all others," is incorrect, as this describes a dominant gene, not a recessive gene.

Option C, "always displays its trait," is incorrect, as recessive genes can only display their trait when paired with another recessive gene.
