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

Explanation:

During the New Moon the far side of the Moon is illuminated by the Sun, while the side that faces the Earth lies in darkness so the Moon is invisible. As the Moon follows its path from the New Moon position more and more of the Earth-facing side becomes illuminated resulting in the “waxing” phases.

Answer:

The purpose of natural selection is not a conscious or intentional one, as it is not driven by a specific goal or purpose. Instead, natural selection is a fundamental process in biology that acts on heritable traits within populations over generations. It is a key mechanism of evolution.

Explanation:

The primary outcome of natural selection is the adaptation of organisms to their environment. Individuals with traits that are advantageous in a particular environment are more likely to survive, reproduce, and pass on those beneficial traits to their offspring. Conversely, individuals with traits that are disadvantageous are less likely to survive and reproduce, leading to a reduction in the frequency of those traits in the population over time.

Natural selection, therefore, acts as a filter that shapes the characteristics of populations, favoring traits that enhance an organism's survival and reproductive success in a given environment. Over many generations, this process can lead to the development of new species or the modification of existing ones, as populations accumulate adaptations that allow them to thrive in different ecological niches.

It's important to note that natural selection does not have an end goal in mind, nor does it necessarily lead to the "best" or most advanced organisms. Instead, it is a consequence of the interactions between organisms and their environment, constantly shaping and refining the traits of living beings based on their ability to survive and reproduce.

The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.

By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.

In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.

The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.

The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.

Contaminated water is a type of water that is harmful to human beings due to the presence of harmful substances, pollutants, or impurities that make the water unsafe for drinking or other household uses. The characteristics of contaminated water can be identified through various indicators, which can either be physical, biological or chemical.

Physical indicators are visible and may include color, taste, and odor, while biological indicators are not visible and may include bacteria, viruses, and protozoa. Chemical indicators may include heavy metals, pesticides, and organic compounds, among others.

Physical Characteristics: Physical characteristics of contaminated water include cloudy or turbid appearance, unusual taste or odor, or discoloration of the water. The color may range from yellow to brown, blue to green, or even black.

Biological Characteristics: Biological characteristics of contaminated water include the presence of bacteria, viruses, or protozoa. These microorganisms can cause diseases such as diarrhea, typhoid, cholera, and dysentery.

Chemical Characteristics: Chemical characteristics of contaminated water include the presence of heavy metals such as lead, arsenic, or cadmium. Pesticides and fertilizers can also contaminate water and affect human health. Organic compounds like benzene and toluene can also be present in contaminated water, which can lead to health problems such as cancer and nerve damage.

Therefore, it is important to test water sources regularly to identify and monitor any contaminants that may be present. This can help prevent health problems associated with the use of contaminated water.

D: Golgi complex

Answer:

Do Eukaryotic Cells have Mitochondria?

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.

What is a  Eukaryotic cell?

A eukaryotic cell is one of two different types of cells. Organisms that are based on the eukaryotic cell are called “eukaryotes” and include plants, animals, fungi, and protists.

What is Mitochondria?

The mitochondrion (plural mitochondria) is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is the power house of the cell; it is responsible for cellular respiration and production of (most) ATP in the cell. Each cell can have from one to thousands of mitochondria. Mitochondria also contain extranuclear DNA that encodes a number of rRNAs, tRNAs, and proteins.

Explanation:

The plant evolved to take advantage of the elephant's consumption of the seed and evolved in a way so that germination is only possible when it was digested and pooped out. This is a method called seed dispersal and can be seen all across the world, like with birds. The mutual benefits of animals/plants with other animals/plants in the animal kingdom are called mutualism.

Explanation:

A bat just picks up on the sound waves but does actualy hear stuff

D. A bat would be least affected by sound frequencies of 25,000 to 100,000 cycles per second. Bats use ultrasonic frequencies in their echolocation calls to navigate and locate prey, they have specialized ears and auditory systems that allow them to hear and process these high frequency sounds. While other animals like human, cheetah, porpoise and house cat would not be able to hear these ultrasonic frequencies and would not be affected by them.

The correct statements that accurately summarize why cold weather events are not considered evidence refuting climate change are A, D, and E.

Firstly, weather refers to short-term conditions while climate refers to long-term conditions. Therefore, a single cold weather event or even a few cannot be used to argue against the long-term trend of climate change. Secondly, climate change does not mean that all places change in the same way at the same time. This means that while some areas may experience extreme heat, others may experience cold temperatures. Lastly, abnormally cold weather conditions can actually be caused by warming at the poles. As the poles warm, the jet stream can weaken and move south, allowing colder air to move into regions that are not typically cold. Therefore, cold weather events are not a refutation of climate change, but rather a potential consequence of it. It is essential to focus on long-term trends in global temperatures and carbon dioxide levels to understand the impacts of climate change accurately.
