Scientists believe that over 99 percent (D answer option) of species that once existed on Earth are now extinct. This can be known by archeologist research, which allows us to know what species lived in the past by studying the soil, its different layers, and the found fossils, dating with high precision how many years ago those organisms inhabited our planet. With these research tools, we have known that there were at least five massive extinctions on the Earth, where aquatic and terrestrial species perished, and they are the Ordovician-Silurian (around 440 mya), Devonian, the Permian-Triassic, the Triassic-Jurassic, and the Cretaceous-tertiary (65 mya) extinctions.

In the given equation, Ek represents the kinetic energy of an object.

Kinetic energy (Ek) is a form of energy associated with the motion of an object. It is dependent on both the mass (m) and the velocity (v) of the object.

The equation Ek = (1/2)m\(v^2\) represents the formula to calculate the kinetic energy of an object.

The symbol "Ek" is commonly used to represent kinetic energy in scientific calculations and equations. By plugging in the values of mass and velocity into the equation, one can calculate the amount of kinetic energy possessed by the object.

The kinetic energy of an object increases with both its mass and velocity. As the mass increases, the object has more particles in motion, contributing to higher kinetic energy.

Similarly, as the velocity increases, the speed at which the object moves also increases, resulting in greater kinetic energy.

Therefore, understanding and calculating kinetic energy is important in various scientific and engineering applications, such as studying the movement of objects, analyzing collisions, or designing efficient systems.

Ecological succession and evolution are both processes that affect the population of red foxes in different ways. Ecological succession involves the gradual and predictable changes that occur in a community of organisms over time while evolution refers to the changes in the genetic makeup of a population over time.

Ecological succession involves the gradual and predictable changes that occur in a community of organisms over time. It is driven by both biotic and abiotic factors and is classified into two main types: primary and secondary succession. During primary succession, organisms colonize a newly formed area that lacks soil and organic matter.

Over time, these pioneer organisms create soil and organic matter, which allows for the growth of more complex plants and animals. Secondary succession occurs after a disturbance such as a fire or flood has occurred, and it involves the gradual return of a community to its original state. Ecological succession can affect the population of red foxes in several ways.

For example, as vegetation grows and changes, the availability of food and shelter for red foxes can also change. This can either increase or decrease the population of red foxes depending on the availability of food and other resources. Furthermore, as other animal populations change due to succession, this can also impact the population of red foxes through predation or competition.

Evolution, on the other hand, refers to the changes in the genetic makeup of a population over time. This occurs as a result of several mechanisms, including natural selection, genetic drift, and gene flow. Over time, these changes can lead to the formation of new species and the extinction of others.

Evolution can affect the population of red foxes in several ways. For example, if a population of red foxes undergoes genetic changes that allow them to better adapt to their environment, this can increase their survival and reproduction. Conversely, if changes in the environment reduce the survival and reproduction of red foxes, this can decrease their population.

Overall, ecological succession and evolution can both affect the population of red foxes, but in different ways. Ecological succession involves changes in the availability of food and other resources, while evolution involves changes in the genetic makeup of a population over time.

A biophilia ecosystem service is the sensation of being among a forest of trees, some of the largest and oldest organisms to have ever existed on Earth. Edward O. Wilson, a biologist and naturalist, invented the word "biophilia" to explain how people are inherently drawn to the natural world.

The advantages individuals experience from being in a natural setting include bettering their physical and mental health, increasing their creativity and productivity, and feeling more content.

These advantages are referred to as "biophilia ecosystem services." In this aspect, trees are especially crucial since they offer a range of ecosystem services including clean air, water filtration, and wildlife habitat.

Answer:

The gravitational acceleration in the surface of the moon is 1.63 m/s^2

Explanation:

The gravitational acceleration at a distance R of an object of mass M, is given by:

g = G*M/R^2

Where:

G is the gravitational constant.

G = 6.67*10^(-11) m^3/(kg*s^2)

We could think that all the mass of the moon is at its center, then at the surface of the moon, the distance will be equal to the radius of the moon, thus:

R = 1740km

But we want to work with meters, so remember that:

1km = 1000m

then:

1740km = (1740)*1000m = 1740000m

R =  1740000m

And the mass is just:

M = 7.4x10^22 kg

If we input all that in the gravitational acceleration equation, we get:

g = (6.67*10^(-11) m^3/(kg*s^2))*(7.4x10^22 kg)/( 1740000m)^2

g = 1.63 m/s^2

The gravitational acceleration in the surface of the moon is 1.63 m/s^2

When you eat, food enters your alimentary canal. The alimentary canal is a series of organs that form a pathway from your mouth to your anus.

As food moves down this pathway, it's processed and changed to waste. After food is modified to waste, it's pushed out of your body in a bowel movement.

The stomach breaks down food into a liquid mixture. The small intestine absorbs nutrients from the liquid mixture. What remains is a liquid waste. The large intestine (colon) absorbs water from the liquid waste, converting it into solid waste (stool).

Nerves throughout your alimentary canal tell your muscles how fast to contract. Muscles within the intestines contract to move food and waste through the digestive tract. The rectum stores stool until a movement occurs. The anus is the opening where stool leaves the body.

When an engineer at a transmission station reports receiving noise, it means that they have detected unwanted and disruptive signals or interference in the transmission system. This noise can manifest as electrical disturbances, random signals, or other forms of electromagnetic interference that disrupt the quality and clarity of the transmitted information or data.

Receiving noise in a transmission system can have various causes, including environmental factors, electrical equipment malfunctions, electromagnetic interference from nearby sources, or signal degradation during transmission. It is essential for the engineer to identify and address the source of the noise to ensure the integrity and reliability of the transmitted signals. This may involve troubleshooting the equipment, adjusting signal filters, implementing shielding measures, or improving the overall transmission system design to minimize noise and maintain signal quality.

Vector-borne diseases are human illnesses caused by parasites, viruses and bacteria that are transmitted by vectors.

Infections known as vector-borne illnesses are those that are spread by the bite of an infected species of arthropod, including mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Being cold-blooded (ectothermic), arthropod vectors are particularly susceptible to climate influences. Mosquitoes can transmit the Zika virus, West Nile virus, Chikungunya virus, dengue, and malaria to humans. Direct touch, droplets, a vector like a mosquito, a vehicle like food, or the airborne route are all possible modes of transmission.The tick is the most prevalent vector. Mosquitoes are the most prevalent and are the primary carriers of many dangerous illnesses.

In September the earth will be experiencing  an equinox

Equinoxes occur between March and September. When the Sun's rays strike the equator at midday and at a 90° angle, it is considered an equinox.  It stands for the idea that day and night have equivalent lengths. The sunset and dawn are separated by 12 hours everywhere on Earth. One may observe how quickly the sunset and dawn hours shift throughout the day the farther one goes from the equator.

Whereas, solstices occur in June and December. The contrary is visible close to the solstices. For a few days, both the sunset and sunrise appear to be constant. Over the course of the year, the time of day when the sun is directly overhead where one lives also gradually changes.

Explanation:

photosynthesis the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

6CO2 + 12H2O + → C6H12O6 + 6O2 + 6H2O

Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of breathable oxygen and water.

Answer:

The process of photosynthesis is commonly written as:

6CO2 + 6H2O → C6H12O6 + 6O2.

This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
