Answer:

75% would have the dominant traits for coat length, 25% would have recessive trait for coat length.

Explanation:

After completing a punnet square, we could find that our genotypes are 25% LL, 50% Ll, and 25% ll.

If these genotypes were to be physically expressed, LL and Ll would both be expressed as showing the dominant trait.

This means that 75% would have the dominant traits for coat length and 25% would have recessive trait for coat length.

I hope this was helpful! Let me know if you need any clarity.

Final answer:

When determining the offspring phenotypes of two heterozygous dogs (Ll x Ll) for coat length, a Punnett square reveals a 3:1 phenotypic ratio, resulting in three-quarters of the progeny having long fur (dominant) and one-quarter having short fur (recessive).

Explanation:

Understanding Offspring Phenotypes from a Genotype Cross

In genetics, when determining the proportion of offspring phenotypes, specifically with coat color and texture traits, a Punnett square is used commonly. This allows us to visually see the potential genotypes and phenotypes of the progeny when the parents have known genotypes. When two dogs that are heterozygous for a trait mate, each parent has one dominant and one recessive allele for the trait in question. To determine the proportion of phenotypes, you need to establish the alleles for each trait. For example, if we denote 'L' as the dominant allele for long fur and 'l' as the recessive allele for short fur, two heterozygous dogs would have the genotype Ll.

Setting up a Punnett square for Ll x Ll:

The first row and column will have the alleles from each parent (L and l).

By filling out the squares, we predict the potential genotypes of the offspring.

The resulting genotype ratio for Ll x Ll is: 1 LL (homozygous dominant), 2 Ll (heterozygous), and 1 ll (homozygous recessive).

The phenotypic ratio would be:

3 long fur (1 LL and 2 Ll, since L is dominant)

1 short fur (1 ll, as both alleles are recessive)

This gives us a phenotypic ratio of 3:1, where three-quarters of the offspring will have long fur, and one-quarter will have short fur, assuming that long fur is the dominant phenotype associated with the L allele.

Answer:

No, it is a cycle, so it repeats cyclic.

Explanation:

The cell cycle is divided into two main phases: interphase and mitotic phase.

Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division, formation of two daughter cells (mitotic phase).

Mitotic phase is subdivided into four phases:

The cell cycle is a regulated process with checkpoints, maintaining accurate progression through phases like interphase, mitosis, and cytokinesis to avoid issues like uncontrolled cell division.

The cell cycle consists of an orderly sequence of events, starting from interphase to cell division, encompassing phases like G₁, S, G₂, and mitosis.

Internal controls called checkpoints monitor each step of the cell cycle to ensure proper progression, with three major checkpoints in G₁, G₂/M transition, and metaphase.

Precise regulation by chemical messengers inside and outside the cell ensures accurate movement from one cell cycle phase to the next, crucial in preventing uncontrollable cell division, such as in cancer.

Answer:

Deforestation negatively impacts the carbon cycle as trees play an important role in balancing the amount of carbon in the atmosphere.

Explanation:

Deforestation is one of the most damaging activities to the environment due to different reasons but mainly because it releases important amounts of carbon dioxide to the atmosphere due to the logging and burning of forests and also leads to the reduction of fauna populations because of habitat destruction.

In this case, cutting white and red pines and then setting a pine acreage on fire disrupts the carbon cycle because:

a) [As stated above] Trees play an important role in balancing the amount of carbon dioxide (CO2) in the atmosphere as there is less photosynthesis carried out by plants - important part of the carbon cycle.

b) When trees (wood) are burned, the carbon that was formerly stored is released into the atmosphere as CO2, leading to another disruption in the carbon cycle.

While the pile of ashes and log have similar colors, the change in size, odor, and hardness, and the difference in combustibility indicate that a chemical change has resulted in a substance with a different identity. Furthermore, the ashes cannot be converted back into a log.

Answer:

Because haploid organisms have only one set of chromosomes

Explanation:

Haploid organisms, unlike diploid that contain two sets of chromosomes (2n), have only one set of chromosomes (n). This means that they only have one gene copy and one allele (variant) for that gene. So, there is no recessive or dominant relationship.

Humans are diploid organisms, meaning that their cells have 2n chromosomes with the exception of gametes. Gametes are formed during the reduction division (meiosis) in which chromosome number is reduced to half.

So, when to gametes fuse, during the fertilization, formed new organism contain two sets of chromosomes (one from father and one from mother).

The concepts of 'dominant' or 'recessive' alleles apply only to diploid organisms that have two copies of each gene. In haploid organisms, which only have one copy of each gene these concepts don't hold, as there's no 'other' allele present for expressing dominance or recessiveness.

In biology the concept of alleles being dominant or recessive only applies to diploid organisms, which carry two copies of each gene. However, haploid organisms, like some fungi, algae, and many microorganisms, only have one set of genetic information, or genome. Therefore, they contain only one version of each gene which eliminates dominant or recessive traits.

Consider Mendel's pea plants. Here the two versions of each gene (alleles) interact to produce physical traits or phenotypes. For instance, taking a gene dealing with seed color the yellow-seed allele is dominant and the green-seed allele is recessive. In a cross between a homozygous yellow-seed plant (YY) and green-seed plant (yy), we would find that all the F1 hybrid offspring possess yellow seeds because yellow trait (Y) is dominant.

However, in haploid organisms, a gene directly expresses itself without any suppression or dominance. As there is only a single copy of each gene present, there's no 'other' allele to be dominant or recessive over. Hence, alleles in haploid organisms cannot be referred to as dominant or recessive.

They’re genetically different because they only possess half the genes from each parent, so they’re not indentical

Genetic recombination during meiosis makes erotically reproduced offspring genetically different from their parents.

Reproduction may be defined as a biological process through which living organisms give rise to offspring which are fertile in nature.

Due to the fusion of two gametes that are coming from two different parents causes segregation and genes from both the parents are intermingled to develop an offspring. As a result of this, variations may occur in the resultant offspring.

Therefore, genetic recombination during meiosis make erotically reproduced offspring genetically different from their parents.

Hey there! Thanks for posting your question to Brainly®! Here's my full explanation and answer for you. Hope it helps you out!

Answers:

Explanation:

- According to National Geographic, 80% of the world’s plants and animals live in forests, and many cannot live elsewhere. With so many of the world’s plants and animals live in forests, that a significant reduction in that habitat, whether tropical rainforest or northern evergreen forest has an impact on biodiversity. Worse, many endangered plants and animals live only in a certain kind of forest habitat. Those species can be lost entirely or can become extinct in the wild very easily.

Climate change

- Cutting down the trees also removes a mechanism to regulate the temperature in forested areas. Hotter days and cooler nights put additional strain on the remaining plants and animals. Growing trees trap a good deal of carbon dioxide. That function cannot be fully replaced by planting single crops, like soy or hemp. The plants are good at holding moisture, trees in particular. Without forest cover, deserts can advance and push out remaining plants and animals.

Loss of soil fertility

-Forested land can be attractive for agriculture because it seems so fertile. In fact, this often isn’t so. The seeming fertility of a rainforest depends on the complex relationships between a variety of plant species. Clearing an area to plant soy or hemp just exposes soil that is high in nutrients at first.  After a few growing seasons, the soil is exhausted and the farmers move on.  The trees and brush in a forest help prevent soil from running off into lakes and rivers and polluting them.

Flooding

- Forests absorb heavy rains that otherwise could run directly into rivers and streams. After a storm, or after several rainy days, a local river can rise to flood stage, even with forests taking up much of the water. Without greatly reduced forest cover comes greatly increased runoff and flooding. Because so much of the world’s population lives along rivers, indiscriminate cutting and burning of forests can be a real threat to lives and property downstream.

Final answer:

Calcium and potassium are two important minerals for the nervous system, vital for nerve function and muscle contraction. A balanced diet that includes these minerals, along with vitamins, healthy fats, and sufficient hydration, is essential for maintaining a healthy nervous system.

Explanation:

Two important minerals for the nervous system are calcium and potassium. These minerals play a crucial role in nerve transmission and muscle function. Calcium is essential not only for maintaining strong bones and teeth but also for muscle contraction, nerve function, and blood clotting. Potassium, on the other hand, is a major cation inside cells and is vital for the proper functioning of the heart, muscles, kidneys, and nerves. Both minerals are involved in cellular processes that include muscle contraction and nerve conduction, making them indispensable for a healthy nervous system.

In addition to these minerals, maintaining overall nervous system health also requires adequate intake of vitamins, healthy fats, and hydration. For instance, vitamins B₁ and B₁₂ are critical for nervous system health, while healthy fats, such as those found in nuts and fish, help insulate the axons of neurons and may enhance memory and learning. Drinking plenty of water helps prevent dehydration, which can negatively impact cognitive function.

Explanation:

The worm that the scientist is least likely to be observing, given that it has a smooth and soft outer body and was found inside a host, is a tapeworm. This is because tapeworms are flat-bodied worms that are segmented, and known scientifically as cestodes, unlike roundworms which are non-segmented and have a round body. The other options listed, such as earthworms, pinworms, and hookworms, are all types of roundworms or nematodes, which generally have round, non-segmented bodies and would fit the description of a worm with a smooth and soft outer body.

Answer D: Offshore wind turbines have more consistent wind power and speed compared to on land wind turbines.  

Explanation:  

Offshore wind turbines do not need land space. There are no trees that would interfere with the wind power and speed. Offshore wind turbines do not use water.

Offshore wind turbines are more advantageous because they have access to more consistent and stronger winds, potentially generating more energy. Hence, option D is correct.

Offshore turbines can utilize the steadier and stronger winds found over bodies of water, and because they are usually located far from shore, they are less likely to conflict with land-based uses and aesthetic concerns. Moreover, they have the potential to generate more energy due to these stronger and more consistent winds.

Answer:

Find Net Primary Production of tundra plants

Explanation:

Gross primary production (GPP) is the total amount of energy traped from the sunlight. It is a chemical energy that plants (primary producers) create as a biomass. One part of this energy is used for the process of cellular respiration, while the rest is known as net primary production (NPP). NPP is the measure of energy gain in plants or the rate at which the plants produce useful energy. It can be calculated:

NPP = GPP - cellular respiration

Simply saying, NPP is the difference between total trapped carbon (from the photosynthesis) and carbon that is lost (through the cellular respiration).

The two main factors causing global climate change are human activities, specifically the emission of greenhouse gases, and natural causes including variations in solar intensity and volcanic eruptions. These contribute to global warming and other climatic changes.

The two significant factors causing global climate change are human activities and natural causes. Human activities, such as the burning of fossil fuels, lead to the release of high amounts of greenhouse gases like carbon dioxide and methane into the atmosphere, thus causing global warming and subsequent climate changes. This is known as the greenhouse effect.

On the other hand, natural causes such as variations in solar intensity and volcanic eruptions also contribute to climate change. Variations in solar intensity directly affect the earth's temperature, while volcanic eruptions release gases and solids that can have a cooling effect on the global climate.

Understanding these causes can help address problems like more intense storms, changes in precipitation affecting agriculture, the reduction in rainforest biodiversity, and rising sea levels which are all potential consequences of global climate change.

•B. a form of energy is required to be input so it can become orderly again

Explanation:

Order can be restored from a disordered system by inputing energy. The energy helps restore back the orderliness in a system.

We know that entropy is the state of randomness or disorderliness of the particles of a system. Entropy increases with rise in temperature. When the heat energy that causes temperature rise is removed from a system, the kinetic energy require for molecules to move is reduced and orderliness can gradually be approached.

For example, heating of water causes agitation of its molecules. The randomness of it particles increases. This is seen in the phase change from liquid to gases. As temperature is lowered, the water cools and orderliness is approached again. We can approach more orderliness by putting the water in a refrigerator.

In some systems, we can bring gases into a more ordered state by compression. The pressure applied to compress gases is a form of energy because work is done to bring the molecules into close contact as seen in a gas cylinder.

The main factors that led to a boom in human population size in the last 300 years include advancements in medical technology, increased agricultural productivity, industrialization, and improved standards of living. Population A would increase by more people in one year due to its higher growth rate. The relationship between population density and population distribution is that population density is a measure of the number of people living per unit area, while distribution refers to the pattern of where people live. Urbanization relieves some pressure on ecosystems as it concentrates human impact into smaller areas, allowing the regeneration of ecosystems in non-urbanized regions.

Historically, the human population grew at a slow rate until the onset of the Industrial Revolution, which led to improved medicine, sanitation, and food production, promoting a rapid increase in population. Population A's annual growth rate of 3.3 percent would result in a larger absolute increase in numbers compared to Population B with an annual growth rate of 1.8 percent, despite the initial population size difference. The concept of population density is distinct from distribution; densely populated areas might be unevenly distributed if large regions are sparsely inhabited. Urbanization can reduce pressure on ecosystems located away from cities because it centralizes resource consumption and waste production, allowing undisturbed regions to maintain or recover their natural ecological functions.

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway.

Examine the accompanying wind rose diagram. Based on the information shown, determine the correct answers to the following questions.

Drag the appropriate labels to their respective targets. Note that there are twice as many blanks as answer choices. In other words, only half of the targets need to receive a label. Pay attention to the color coding and think carefully about the best position for each label when multiple locations seem possible.

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway. This relationship explains why planes circle above an airport so they can land in the correct orientation, and why they reorient themselves after taking off in a direction other than the direction they wish to fly. In our example, the longest spoke in the wind rose diagram indicates prevailing winds are coming from the NE and blowing toward the SW. Therefore, the correct orientation for the runway is along this path, with planes taking off in the SW to NE direction. This wind pattern can be found where NE trade winds are located.
