Kinetic energy = 1/2 * mass * velocity^2 so Ke = 1/2*(155*10^3 g)*18^2 which is 25,110,000 joules.

Answer:

31,000 J

Explanation:

using KE = 1/2mv^2 (m stands for mass, v stands for velocity) we can do the math and the answer is 31,000J because the mass in the question listed is 155 kg and the velocity (aka speed) is 18 m/s.

kinetic energy (aka KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared.

(1/2 * 155 kg) * 18 m/s^2 =  31,000J

Limited sunlight is a key resource likely to be limited for smaller trees, due to overshadowing by larger trees. While water and nutrients may also be restricted, sunlight is crucial for photosynthesis and growth.

The most likely limited resource for smaller trees is access to sunlight. This is because trees, particularly smaller ones in densely forested areas, compete for sunlight to perform photosynthesis, which is critical for their growth and energy production. Larger trees often overshadow smaller ones, limiting their sunlight exposure. Water availability could also be a limiting factor; however, smaller trees have less extensive root systems and therefore require less water than mature trees. Additionally, nutrients in the soil are essential for tree growth, and smaller trees might struggle if they are in competition with larger trees with more established root systems. In contrast, reproduction, shelter, and defense against herbivory are unlikely to be as influential since these factors do not directly affect the immediate growth and survival of smaller trees in the same way that access to sunlight and other resources do.

Answer:

The answer would be B) A person vomits after eating spoiled food

Explanation: Since the question is talking about internal stimulus think about what happens inside someone, the other options are examples of External stimulus which happens outside someone like using your external senses (hearing, sight and touch)

Hope this helps

The correct response to an internal stimulus is B: A person vomits after eating spoiled food. The vomiting reflex is triggered internally by the body in response to toxins, making it a reaction to an internal stimulus.

The question is asking for an example of a response to an internal stimulus. An internal stimulus comes from inside an organism and causes a response that is internally regulated. In this case, the correct answer is B: A person vomits after eating spoiled food. This is a defensive response triggered by the body's internal detection of toxins in the spoiled food. Vomiting is a mechanism that the body uses to expel these toxins and protect itself.

Other options mentioned in the question, such as an animal responding to a ringing bell (Pavlov's experiment) or a person pulling their hand away from a hot surface, are responses to external stimuli. These are reactions prompted by environmental factors outside the body. The distinction between internal and external stimuli is crucial for understanding how organisms, including humans, respond to changes in their environments.

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.

The major boundaries of the Earth's interior were discovered by seismologists. In 1909, Andrija Mohorovičić, a Croatian seismologist, discovered the boundary between the crust and the mantle by observing the sudden increase of seismic waves as they passed from the crust to the mantle.

Seismologists discovered that most of the mantle is solid by evidence from seismic waves, heat flow, and meteorites.

A mantle is a layer within a planet that is bordered below by the core and above by the crust. Mantles are composed of rock or ice and are the largest and most massive layer of a planet. The top and lower mantles differ little, but the lower mantle is more substantial than the higher.

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.

C6H12O6 (glucose) + O2 (oxygen) -> CO2 (carbon dioxide) + H2O (water) + sunlight energy (ATP). The reaction is called cellular respiration and it is used in plants and animals to break down sugars into usable energy to complete bodily functions.

Explanation:

A chemical reaction is defined as the process in which one or more substances reacts to form one or more products which are chemically transformed means the constituent atoms of the reactants are rearranged unlike physical reactions. No new atoms are  created or destroyed, bonds between the atoms in the reactants are broken and the atoms rearrange themselves and form new bonds to make the product.  For example iron and oxygen combine to form rust, sodium acetate is formed by the combination of vinegar and baking soda etc.

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.

Final answer:

A gene is a section of a chromosome that codes for a specific trait, with alleles being different versions of these genes, leading to variation in the traits exhibited.

Explanation:

A section of a chromosome that contains genetic information for one trait is known as a gene. Genes are specific nucleotide segments located on chromosomes that code for proteins, which in turn determine our traits, such as hair color or blood type. Homologous chromosomes are pairs of chromosomes in a diploid organism that are the same length and have genes at the same locations or loci. However, different versions of a gene, called alleles, can exist and contribute to the variations observed in traits. For example, the gene for blood type has three different alleles: A, B, and O, and the combination of alleles inherited from our parents determines our blood type.

Explanation:

All ecosystems are capable to support a certain number of organisms, beyond which the rate of consumption of their resources (by the increased population) will be  much  faster than the rate at which they are replenished and hence the ecosystem will destabilize.

This population which an ecosystem can sustain without any pressure on its resources thereby preserving them for future generations is called  the carrying capacity of an ecosystem.

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.

Displacement behavior usually occurs when an animal is torn between two conflicting drives, such as fear and aggression. Displacement activities often consist of comfort movements, such as grooming, scratching, drinking, or eating. It has been scientifically proven that the honey does a waggle dance during behavioral transitions when they are foraging.

A) the waggle dance of the honey bee is the answer.

Final answer:

Displacement in the animal kingdom is exemplified by the waggle dance of the honey bee, through which worker bees can signal the location of distant food sources to their hive.

Explanation:

One of the few examples of displacement in the animal kingdom is the waggle dance of the honey bee. This innate behavior allows worker honey bees to communicate the existence and location of a food source that is situated some distance away from their hive.

The waggle dance involves a figure-eight motion, which conveys both the distance and direction to the nectar. Moreover, bees take into consideration the movement of the sun as they perform their dance. However, it is important to note that a honey bee must have seen the nectar first in order to conduct this dance. In contrast to human language, animals typically do not communicate about things they have never seen before.
