Assuming complete dominance for both genes, the parents genotypes are bbEe and Bbee. Among the offpring, the Expected genotypes are: 1/4 BbEe, 1/4 Bbee, 1/4 bbEe, 1/4 bbee. And the Expected phenotypes are: 1/4 brown eyes and normal vision, 1/4  brown eyes and express extremenearsightedness, 1/4 blue eyes and normal vision, 1/4 blue eyes and express extremenearsightedness.

Complete dominance is the inheritance pattern in which the dominant allele can hide the expression of the recessive allele when both of them are together in heterozygous individuals. In these cases, only the dominant phenotype can be expressed.

In the exposed example, we will assume complete dominance for both genes.

Gene for extremenearsightedness

Available data:

- blue eyed (bb)

- normal vision (E-)

- his mother was affected (ee)

The fact that his mother was affected suggests the man is heterozygous because he received one recessive allele from his mother. So he has normal vision but is heterozygous for the trait, Ee.

Homologous chromosomes are paired because they carry the same genes in the same order, although the alleles for each trait may differ.

During meiosis, the homologous chromosomes align during prophase I and exchange genetic material through a process called crossing over, which contributes to genetic diversity.In human beings, a pair of homologous chromosomes is present in every cell, one from each parent.

In females, the two X chromosomes are homologous pairs, while in males, the X and Y chromosomes are not homologous pairs since they carry different genes. During fertilization, the homologous chromosomes from the two parents pair up, and each gamete contains only one of each homologous chromosome.

The situation in question illustrates the competitive exclusion principle by demonstrating how the two species were forced to occupy different locations due to the fact that they share the same niche (meaning that they occupy the same role in an ecosystem).

The competitive exclusion principle states that two species that occupy the same niche cannot co-exist in the same ecosystem. At the very least, they cannot co-exist while maintaining a stable population value. What this means is that since the two species of barnacles have the same niche, which is to feed on plankton using the same methods, they cannot occupy the same location.

This principle is demonstrated by the question that was given because it shows that despite being in close proximity, the two species of barnacle, which share the same niche, have differentiated to occupy different locations in order to avoid competing for the food source present in one.

Current meat industry practices harm the environment in two principal ways: 1) deforestation and 2) green gas emissions. Farm animals, like cows, sheeps or pigs are not adapted to walk through forests. So, in order to engage in the meat business, farmers have to destroy the arboreal vegeation. Tree depletion per se releases a lot of CO2, which aggravates climate change. Besides, when trees are removed, soil loses many of its properties, which ultimately could lead it to desertification; the worst possible case, in which soil is no longer fertile. The second point, is related with the animals per se. Cows release methane as they digest grass, methane per cow is neglible. But when we sum up millions of cows, every day, every year, for decades, the result is different. One of the main sources of current green gas emissions are cows. This are the main points, but there are other issues relevant, like biodiversity loss that is closely associated with meat industry (related to point 1). Switching to veganism, could have an environmental basis, but it is important to cover one hole, without opening a new one. That is, vegetables must be produced in a sustainable manner, without pesticides, and strict policies that ensure harmony with the environment. Which is hard to find nowadays. Another option is to reduce meat consumption, so you can have a mix diet: you have yiour vegan days, then you return to meat. The point is slowing down meat consumption.

In a case whereby Emmings are small mammals that reproduce quickly. A lemming population often grows so quickly .This example best supports the ideas of option A Malthus Principle of Population.

The Malthusian principle of population, also known as the Malthusian theory of population, was proposed by Thomas Malthus in his 1798 book "An Essay on the Principle of Population."

According to Malthus, population growth is exponential, while the growth of resources is linear. Therefore, if left unchecked, the population will eventually outgrow the available resources, leading to widespread poverty, famine, disease, and ultimately, population decline.

Malthus argued that there are two types of checks that prevent population growth from exceeding available resources: preventive checks, which are actions that people can take to limit population growth, such as postponing marriage or practicing contraception, and positive checks, which are events that limit population growth, such as famine, disease, and war.

The correct hypothesis supported by the data is hypothesis B: Manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.

Based on the given information, neither hypothesis A nor hypothesis D is supported by the data. Hypothesis A suggests that manatees, an abiotic factor (which is incorrect, as manatees are living organisms), experienced a decline in their population due to propeller boats, a biotic factor.

Hypothesis D suggests the opposite, that manatees (an abiotic factor) experienced an increase in their population due to propeller boats (a biotic factor).

Hypothesis B, on the other hand, is supported by the data. It states that manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.

This hypothesis aligns with the information provided, as the graph for manatee population shows a decrease over the same 20-year period in which the number of propeller boats increased.

Therefore, the correct hypothesis supported by the data is hypothesis B: Manatees, a biotic factor, experienced a decline in their population due to propeller boats, an abiotic factor.

Fire can both benefit and threaten forest ecosystems depending on the frequency, intensity, and type of fire.

In some forest ecosystems, periodic fires are essential for the survival and growth of certain plant species. Fires can stimulate the germination of certain seeds, promote the growth of new vegetation, and clear out dead plant material that can hinder the growth of new plants.

However, when fires occur too frequently or are too intense, they can become a threat to forest ecosystems. Intense fires can cause significant damage to vegetation, soil, and wildlife habitats. They can also lead to erosion and soil degradation, which can make it difficult for vegetation to grow back.

Moreover, human-caused fires can pose a serious threat to forest ecosystems. In many cases, fires are started accidentally by people, or intentionally by individuals who want to clear land for agriculture or development. These fires can quickly spread out of control and cause significant damage to forest ecosystems.

Explanation:

Damage to the sun is not a negative way we use science because the sun is very far away from the Earth. The sun is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us. This means that The distance from the sun to the Earth is far and it's difficult for science to have negative effects on the sun. The sun is not easily accessible and sun damage is not easily affected compared to pollution, climate Change, overuse of resources which it's as a result of science negative effect.

The distribution of invertebrates among different colors suggests that the type of predator targeting them might have color preference or selectivity.

The fact that there are significantly more blue invertebrates (30) compared to black (25), brown (25), yellow (6), and orange (4) indicates that the predator might have a preference for blue-colored prey. This preference is evidenced by the higher number of blue invertebrates captured compared to other colors.

Additionally, the predator seems to show a relatively equal preference for black and brown invertebrates since their numbers are the same. However, it is important to note that the sample size of the invertebrates may affect the observed distribution, and further investigation would be required to draw definitive conclusions.

Understanding the predator's color preference can provide insights into its visual perception and hunting strategies. It could indicate that the predator has developed adaptations to target specific color morphs or that certain colors are more conspicuous or attractive to the predator's visual system.

Answer: c

Explanation:

Answer:

Three major types of insect development: a) Ametabolous development typified by the silverfish, b) Hemimetabolous development typified by the cockroach; in some hemimetabola such as termites and grasshoppers there may be more than one stage with wing pads that could be called nymphal; c) Holometabolous development 

The correct answer is option C) exploration of different niches, avoiding competition between life stages.

Each phase of development presents a different habitat and niche, which prevents competition between species, that is, intraspecific competition. In this way, the effectiveness of the animal within its environment is increased, as well as its adaptation to the environment.

The other alternatives highlight stages of development that exist, but are not related to the increase in the number of species or to the justification presented.

New technology is important to the development of theories because it provides a new way to acquire new information. With new technology, researchers can collect data in new and more precise ways, which can lead to new insights and discoveries. It can also allow for the testing of existing theories in new ways or under different conditions, leading to a better understanding of the phenomena being studied. However, the importance of technology in developing theories does not necessarily mean that it replaces old theories or allows for repeated experimentation on its own. Theories are typically developed through a combination of empirical evidence, experimentation, and theoretical modeling, and the role of technology is to provide new tools and methods for gathering and analyzing data.

Because roots get more water then the stem does, it absorbs at least 60% of the water, and if you use a nail that goes into water, it rusts, so that means that it's darker than others.

Explanation:

If you take a nail and place it under water, that means its getting 100% of the water, so it's the same thing with plants. Another reason that this is happening is that its a sign that a plant is unhealthy. So make sure to give it a lot of water( but not too much or it will drown) so it stays a healthy and happy plant.

Answer:

Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are the macromolecules that contain phosphorus. Phosphorus is an important component of the nucleotides that make up nucleic acids.

In DNA, the phosphate group is located on the 5' carbon of the sugar molecule, which is connected to the nucleotide base via a phosphodiester bond. The phosphate groups of adjacent nucleotides form the backbone of the DNA molecule.

In RNA, the phosphate group is similarly located on the 5' carbon of the sugar molecule, but RNA has a ribose sugar instead of a deoxyribose sugar. RNA also typically contains single-stranded nucleotides, rather than the double-stranded structure of DNA.

Overall, phosphorus plays a critical role in the structure and function of nucleic acids, which are responsible for storing and transmitting genetic information.

Answer:

it can't be used to make a protein in that cell.

Explanation:

If a gene is not transcribed in a cell, it can't be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.

The transcription is affected as when the gene has not been transcribed the protein will not make. When a gene is transcribed, protein synthesis can happen.

Gene expression begins with transcription. To create an RNA molecule, the DNA sequence of a gene must be copied. RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).

A gene cannot be used to produce a protein in a cell if it is not transcribed there. If a gene gets transcribed, it will probably be used to produce a protein (expressed). In general, more protein will be produced the more a gene is transcribed.

Therefore, the transcription is impacted since the protein cannot be produced if the gene is not transcribed. Protein synthesis can take place when a gene is transcribed.
