Number 2 is B also because they both have nucleus in their cells.

Final answer:

Descending through the atmosphere causes an increase in outside pressure due to the increasing weight of the air above. Pressure in the atmosphere is related to the altitude, with higher pressure at lower altitudes. So the correct option is B.

Explanation:

As you descend through the atmosphere, the outside pressure is expected to increase. This is because pressure is a measure of the force exerted by the weight of air above you. At higher altitudes, there is less air above you, thus lower pressure. When you descend, more air is above you, and the weight and pressure increase accordingly.

For instance, when a scuba diver descends into the ocean, which is similar in principle to descending through the atmosphere, the water pressure increases significantly at greater depths due to the weight of the water above. In the context of the atmosphere, air molecules are pulled toward Earth by gravity, so the closer you are to the surface, the more compressed the air molecules are, leading to higher pressure. This concept is also explained by air pressure decreasing with altitude due to fewer air molecules being present.

Final answer:

Descending through the atmosphere results in an increase in the outside pressure due to the greater mass of air above you exerting pressure, following the principles of atmospheric pressure and gas behavior.

Explanation:

As you descend through the atmosphere, the outside pressure would be expected to increase. This is because as altitude decreases, the amount of air above you that is exerting pressure increases due to gravity, hence compressing the air molecules closer together. The relationship between altitude and atmospheric pressure is that pressure increases as you move from higher to lower altitudes.

The relevant concepts from the provided information that relate to gas pressure include understanding the behavior of a gas inside a hot air balloon. When the total pressure of an atmosphere increases, as in the case of descending towards the Earth's surface, the pressure on the gas inside the balloon would also increase. This follows the general gas laws where, in a closed system, a decrease in volume and an increase in atmospheric pressure would cause an increase in the gas's pressure.

The biological carbon cycle. Through photosynthesis, green plants use solar energy to turn atmospheric carbon dioxide into carbohydrates (sugars). Plants and animals use these carbohydrates (and other products derived from them) through a process called respiration, the reverse of photosynthesis.

The biological processes in the carbon cycle involve the intake of carbon dioxide by autotrophs to form organic compounds, consumption of autotrophs by heterotrophs which use the organic compounds for energy and exhale CO2, the biological carbon pump process, and the storage and release of carbon in and from various carbon reservoirs.

The biological processes in the carbon cycle primarily involve autotrophs (like plants and algae) and heterotrophs (like animals). The cycle begins with autotrophs, which take carbon dioxide (CO2) from the atmosphere or dissolved form in water bodies to form organic compounds like glucose. This process, known as photosynthesis, requires energy from the sun and results in the release of oxygen as a byproduct.

Next, heterotrophs ingest the autotrophs and break down the organic compounds for energy through the process of respiration, releasing carbon dioxide back into the atmosphere or water bodies. A process known as the biological carbon pump involves autotrophs fixing inorganic carbon which then fall to the sea floor as they die, preventing the consumption and return of their CO2 to the atmosphere by saprobes.

Another important process in the carbon cycle is the long-term, geological storage of carbon in carbon reservoirs, such as atmosphere, oceans, ocean sediment, soil, fossil fuels, and the Earth's interior. Over time, human activities like fossil fuel burning have accelerated the return of stored carbon to the atmosphere, leading to increased atmospheric CO2 levels and concerns about climate change.

A cobaia tem 100% de nascer com cabelo curto, sendo Hh

HH is dominant, so short hair would be answer.

Final answer:

Epistasis is a form of genetic interaction where one gene masks the expression of another gene, which differs from simple dominance which occurs when a dominant allele masks the expression of a recessive allele within the same gene. In the context of the shepherd's purse plant, epistasis results in triangular seeds unless both genes are homozygous recessive, leading to a 15:1 phenotypic ratio when two heterozygotes are crossed.

Explanation:

Epistasis is a genetic phenomenon where one gene interferes with or masks the expression of another gene. The term epistasis comes from Greek roots meaning "standing upon." An epistatic gene that does the masking is referred to as epistatic, while the gene whose expression is masked is called hypostatic. This relationship can profoundly affect the phenotypic ratios seen in genetic crosses, different from the simple dominant-recessive relationships seen in Mendelian inheritance. The biochemical basis for epistasis often involves gene pathways where one gene's function is necessary for another gene further down the pathway to be expressed.

Dominance vs. Epistasis

While dominance refers to the interaction between different alleles of the same gene, with the dominant allele masking the expression of a recessive allele, epistasis involves interactions between different genes. Epistasis can be complex, with multiple gene interactions leading to variations in phenotype that are not predictable by simple dominance. For instance, in shepherd's purse plants (Capsella bursa-pastoris), the presence of a dominant allele in any of two genes results in triangular seeds, overriding the seed shape that would be produced by the other gene. A phenotype of ovoid seeds only occurs when there are two homozygous recessive genes (aabb). Hence, crossing two heterozygotes for each gene (AaBb x AaBb) yields a phenotypic ratio of 15 triangular to 1 ovoid.

Final answer:

Epistasis is a genetic interaction where one gene's phenotype expression masks another gene's expression, differing from dominance that occurs between alleles of the same gene. Examples include the coat color of mice and seed shape in the shepherd's purse plant.

Explanation:

Epistasis is a genetic interaction where the phenotype effect of one gene (epistatic) masks or suppresses the expression of another gene (hypostatic). This is different from dominance, which refers to the interaction between alleles at the same gene locus, with dominant alleles expressing their effects over recessive ones. An example of epistasis is in the coat color of mice, where a mouse with a certain genotype (cc) will always be albino, regardless of the alleles at another locus related to fur color.

Physiological epistasis and statistical epistasis are two concepts related to these genetic interactions. Physiological epistasis involves the actual biological interaction between gene products, while statistical epistasis refers to the measured deviation from the expected genetic ratios in a population. In contrast, dominance only describes the relationship between alleles at a single locus, not interactions across different loci.

Understanding Epistasis through Examples

In the shepherd's purse plant, seed shape demonstrates dominant epistasis. When both genes A and B are present in dominant form with any combination other than homozygous recessive (aabb), the seeds will always be triangular. This genotypic relationship modifies the phenotypic ratio from the standard 9:3:3:1 of a dihybrid cross to 15 triangular:1 ovoid upon crossing heterozygotes for both genes (AaBb x AaBb).

The factor that causes cooler temperatures are being closer to the ocean and ocean current bringing cooler air.

What is temperature?

Temperature can be defined as a scalar quantity that shows the degree of hottest or coldness of a body. It is measured in C⁰ or F⁰.

In the physical environment, the degree of it's coolness depends on the surroundings.

When they moved from Tennessee to California it became cooler due to the environment being closer to the ocean and ocean current bringing cooler air

Cooler temperatures in California compared to Tennessee may be influenced by being closer to the ocean, ocean currents bringing cooler air, and mountain ranges.

The observed cooler temperatures in California, following a move from Tennessee, can be attributed to a combination of geographical and climatic factors. Firstly, being closer to the ocean tends to have a cooling effect on the climate. The proximity to large bodies of water, such as the Pacific Ocean in the case of California, moderates temperatures by preventing extreme heat in summers and maintaining milder conditions in winters.

Secondly, ocean currents play a crucial role. If ocean currents are bringing cooler air, it further contributes to the overall cooling of the coastal areas. The movement of air masses over the ocean can bring lower temperatures, influencing the climate of the adjacent land.

Lastly, the presence of mountain ranges, which is characteristic of California's topography, can also contribute to cooler temperatures. As air ascends the windward side of mountains, it cools and releases moisture, resulting in cooler and more moderate temperatures on the leeward side of the mountains.

In combination, these factors create a climate in California that is noticeably cooler than that of Tennessee, providing a diverse range of environmental conditions shaped by the state's geographical features and its proximity to the Pacific Ocean.

Acute causes of high blood pressure include stress, but it can happen on its own, or it can result from an underlying condition, such as kidney disease. Unmanaged hypertension can lead to a heart attack, stroke, and other problems. Lifestyle factors are the best way to address high blood pressure.

Blood pressure is caused by the force of blood against the walls of arteries.

Blood pressure is the measure of the force that blood exerts on the walls of arteries as it flows through them. It is essential for the circulation of blood throughout the body and for maintaining adequate blood flow to organs and tissues. Blood pressure is determined by two factors: cardiac output and peripheral vascular resistance. Cardiac output is the amount of blood the heart pumps per minute, while peripheral vascular resistance is the resistance to blood flow in the arteries. When either of these factors increases, blood pressure increases as well.

Factors that can contribute to high blood pressure include obesity, lack of physical activity, stress, smoking, excessive alcohol consumption, genetics, and certain medical conditions such as diabetes and kidney disease. Medication can help to lower blood pressure and reduce the risk of heart disease and other complications associated with high blood pressure.

the correct answer is B) its released by the parathyroid gland

After the plants became able to live on land, and the reason for that being the ability for higher glucose production, they managed to influence numerous things on the planet and change it drastically.

Some of the more marking things that happened because of the plants that started to live on land were the change in the composition of the gasses in the atmosphere, the formation of soils, and climate changes.

The plants perform a process called photosynthesis in order to make their own food. For this process they use carbon dioxide. The carbon is used, while the oxygen is a waste product that is released. Over time, through this process, the plants managed to significantly increase the oxygen levels on the Earth, making it suitable for the animals to move in as well on the land.

The increase of oxygen in the atmosphere resulted in climate changes, as the oxygen makes the climate cooler, thus in general the climate cooled off. Also, with their shade, the plants manage to reduce the temperature on the surface, the trees also being able to slow down and affect the low air movements...

The plants, as all organisms, eventually die. When they die, they decompose. In this manner they introduced the land with the first biomass, thus the rocks and the biomass started to mix. Over time this led to the formation of multiple types of different soils.

ice wedging, expands

Freeze-thaw weathering happens when water enters cracks in rocks and freezes, expanding and enlarging the cracks. The water expands because in its solid state (ice), the molecules are more spread apart than in liquid state. This spread-out molecular structure causes the ice to increase in volume and exert pressure on the rock.

In the process known as freeze-thaw weathering, water enters cracks in rocks and freezes. Water expands when it freezes, which makes the cracks in the rocks larger. Water's unusual behavior when it freezes is due to its molecular structure. As temperatures drop, there's less energy to break the hydrogen bonds between water molecules. These bonds stay intact and form a rigid, lattice-like structure known as ice. The ice is less dense than liquid water because the molecules are farther apart. This expansion puts pressure on the surrounding rock and can make the crack larger.
