Answer: the answer is The height of the cliff is 15m

Explanation:

Potential gravitational energy is computed with the formula:

PEgrav=Mgh

Where:

PEgrav = Potential gravitation energy (J)

m = mass (kg)

h = height (m)

g = acceleration due to gravity (9.8m/s^2)

Take note that acceleration due to gravity is a constant.

All you need to do is put in what you know and solve for what you don't know. So your given is the following:

PEgrav = 3,528J

m = 24 kg

g = 9.8 m/s^2

Put that into your formula:

3,528J=(24kg)(9.8m/s^2)(h)

3,528J= (235.2kg*m/s^2)(h)

3,528/235.2= 15

The height of the cliff is 15m.

In 1576, there was an outbreak that followed a drought that stretched from Venezuela to Canada. The association between the drought and outbreak, according to proponents of the viral theory of Cocoliztli, may be explained by a rise in the population of vesper mice, which are carriers of viral haemorrhagic fever, during the rains that followed the drought.

The cocoliztli epidemics in 1545 and 1576 seem to have been hemorrhagic fevers exacerbated by peculiar climatic conditions and brought on by a local viral pathogen. The 20th century saw the Mexican population reach pre-Hispanic levels.

The primary functions of whales include feeding, reproduction, communication, and migration.

Whales are primarily filter feeders or predators, depending on the species.

Filter-feeding whales, such as baleen whales, have baleen plates in their mouths that allow them to filter out small prey, such as krill or small fish, from large volumes of water.

Predatory whales, such as toothed whales, hunt and feed on various marine organisms, including fish, squid, and marine mammals.

Reproduction is another important function for whales. Most whale species have a gestation period of several months, with females giving birth to a single calf.

The calves are nursed with milk from their mothers and rely on their care for a period of time until they become independent.

Communication is vital for whales, as they rely on vocalizations to communicate with other members of their pod.

Whales produce a variety of sounds, including songs, clicks, and whistles, which serve purposes such as mating, social interactions, and navigation.

Migration is a common behavior observed in many whale species. Whales undertake long-distance migrations, often covering thousands of kilometers, to reach feeding grounds in nutrient-rich waters or to reproduce in specific breeding areas.

These migrations are driven by seasonal changes in food availability and environmental conditions.

In summary, the primary functions of whales encompass feeding, reproduction, communication, and migration, all of which are essential for their survival and successful adaptation to their marine environments.

Answer:

Explanation:

Small structural units that contains bundles of axons at intervals nervous  tissue are referred to as tracts within the central system nervous.

They could be a band of nerve connecting the hemispheres of brain and therefore the 2 sides of medulla spinal is.Funiculus could be a tiny bundle of axons surrounded by perinuerium.Canal could be a hollow passage shaped by foramne of vertebrae through that the medulla spinalis passes.

Neurons feature many long, slender projections termed axons, along which electrochemical nerve impulses are transmitted. In the central nervous system (CNS) bundles of these axons are called tracts, whereas in the peripheral nervous system (PNS) they are called nerves.Each nerve is covered externally by a dense sheath of connective tissue, the epineurium. Underlying this layer of flat cells, the perineurium, forms a complete sleeve around a bundle of axons called fascicles.

Surrounding each axon is the endoneurium. The endoneurium consists of an inner sleeve of material called the glycocalyx and an outer delicate meshwork of collagen fibers. Within the endoneurium, the individual nerve axons are surrounded by a protein liquid called endoneurial fluid. The endoneurium has properties analogous to the blood-brain barrier, in that it prevents certain molecules from crossing from the blood into the endoneurial fluid.

Axon length and diameter can vary greatly from between 1 m to 1 mm in length and 1 µm to 20 µm in diameter. The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. Axons in the central nervous system typically show complex trees with many branch points allowing for the simultaneous transmission of messages to a large number of target neurons.

Scanning electron microscope (SEM) can be used to study the details of protein molecules present on the surface of a cell. These give a three-dimensional structure of the molecules. Thus, the correct option is A.

Scanning electron microscope (SEM) is a type of electron microscope, designed to directly study the surfaces of solid objects, that utilizes a beam of focused electrons of relatively low energy is scanned in a regular manner over the specimen to be observed.

Scanning electron microscopes use an electron beam to study samples with a resolution. The electrons are emitted from a filament and collect into a beam in the electron source. The beam is focused on the sample by a set of lenses in the column.

Molecular homology includes amino acids and DNA sequencing, while anatomical homology includes features that are similar in their anatomy. Homology refers to the characteristic of having a common ancestry or evolutionary origin.

This characteristic can be found both at the anatomical and molecular levels. Homology is the phenomenon where different living organisms have a similar anatomical structure or molecular sequences due to their descent from a common ancestor. Homology is one of the fundamental concepts in evolutionary biology, and it's crucial to understand the evolutionary relationships between different organisms. Anatomical homology refers to the structural similarity between different species, which indicates that they share a common ancestor. Examples of anatomical homologies include the similar bone structure of the limbs in different species, such as human arms, bat wings, and whale fins.

Explanation:

As the fishermen catch fish, they use their muscular force to free themselves.

A force exerted by the muscles of animals is known as muscular force.

The mantis shrimp club is a highly specialized appendage found in mantis shrimp, a group of marine crustaceans known for their powerful strikes.

The club is made up of three main regions: the striking region, the coupling region, and the handle region. The striking region is the distal portion of the club and is responsible for delivering the strike. It is made up of a series of mineralized layers arranged in a helical pattern, which allows the club to withstand the forces generated during a strike.

The coupling region is a softer, more elastic region that connects the striking region to the handle region. It helps to transfer the force of the strike and prevents damage to the animal's body. The handle region is the proximal portion of the club and is used to control the movement and orientation of the club.

Mantis shrimp are known for their extremely fast strikes, which can reach velocities of up to 23 meters per second (75 feet per second). This striking velocity is one of the highest recorded in the animal kingdom and is due to the unique structure and composition of the club, as well as the highly specialized musculature used to power the strike.

Answer: Photosynthesis.

Explanation: Plants are considered autotrophs, this means that they can convert inorganic compounds or substances into organic substances. This includes carbon dioxide. When a plant is conducting photosynthesis, they "steal" carbon dioxide (and water) from soil and air and transform that, along with sunlight, into sugar and oxygen. The plant proceeds to utilize the sugar and oxygen as energy.

gravitational force of attraction is stronger on more massive planets such as Jupiter

Gravitational force is stronger on more massive planets, the claim that the gravitational force between objects depends on mass, hence option D is correct.

The force that pulls things toward the center of a planet or other body is called gravity. All the planets are kept in orbit around the solar by gravity.

Earth is subject to the same gravity pull that you are. But your force doesn't really affect our globe because Earth is so much larger than you are.

In our world, gravity the moon is maintained in its circle around Earth by gravity, as are the planets in their orbits around the sun. The gravitational force is equivalent to your weight when you are at rest on or near the Earth's surface.
