Ground-penetrating radar is used by paleoanthropologists to discover new fossil sites or localities.

Paleoanthropologists rely on ground-penetrating radar to uncover and identify potential fossil sites or localities. Ground-penetrating radar (GPR) is a geophysical technique that uses radar pulses to create images of the subsurface.

It allows scientists to "see" beneath the ground without the need for excavation.

By sending into the ground and measuring the reflections that bounce back, GPR can detect variations in the subsurface composition. This includes identifying changes in soil density, the presence of sediment layers, and the possible presence of fossils or other artifacts.

By analyzing the data collected through GPR, paleoanthropologists can pinpoint potential locations where fossils may be buried.

GPR is a non-destructive and non-invasive method, making it particularly valuable in paleoanthropology, where the preservation of delicate fossil remains is crucial. It allows researchers to survey large areas quickly and efficiently, reducing the need for extensive excavations.

By using GPR, paleoanthropologists can prioritize excavation efforts and focus on areas with the highest potential for fossil discoveries.

Answer: The term EVOLUTION in the study of plants is referred to as the adaptive changes that have taken place which may lead to the development of new species that exists and survive in different ways from the species which they evolved.

Explanation:

In the evolution pattern of plants, it has been an increase in the size of plants and a decreasing dependence on water for reproduction These changes can be identified in the life history of bryophytes and the angiosperms both of which belongs to the plant kingdom.

BRYOPHYTES do not have any System for conducting food and water from one part of the plant to another. This restricts their size. Examples of bryophytes include: liverworts and mosses. Also, bryophytes show a distinct alterations of generation, which means there are presence of sexual( gametophyte) and asexual stage( sporophyte) that are often morphologically, and sometimes chromosomally, distinct. The sporophyte is always attached and dependent on the gametophyte which produces motile male gametes known as spermatozoa and non-motile female gametes known as ova. Water is essential for fertilization.

ANGIOSPERMS are the flowering plants. They form the largest group in the plant kingdom. There are thousands of species which differ greatly in size and form. They have adapted to almost every kind of habitat. They are seed producing vascular plants. They have well developed roots, stems and leaves. The efficient seed dispersal of seed plants account for their continued existence and widespread occurrence. Fertilization is brought about by pollination, therefore they do not depend on water for reproduction.

From the above description of bryophytes and angiosperms, the ANGIOSPERMS are more EVOLVED than the BRYOPHYTES because they possess water conducting vessels with unrestricted sizes and do not depend on water for reproduction while bryophytes are restricted in size and depends on water for reproduction.

Answer:

Protists decompose dead materials, returning nutrients to the soil.

Explanation:

The role of protists that has the most positive effect on maintaining the plant population in an ecosystem is that they are primary producers.

A protist is a single-celled organism that exists within various environments, such as water, soil, and animal hosts. They may also be either heterotrophs or autotrophs, based on their feeding habits.

Protists that are heterotrophic consume other organisms or dead organic material to obtain the nutrients they need to survive, while those that are autotrophic are primary producers that use energy from the sun to convert carbon dioxide into organic compounds, which then make up the foundation of many food chains.

Proteins that are primary producers have the most positive effect on preserving plant populations in an ecosystem. They play an essential role in maintaining the plant population in an ecosystem by serving as the main source of food for herbivores.

The food chain in any ecosystem begins with primary producers, such as protists, which transform energy from the sun into organic matter, making them an essential component of the ecosystem.

The enzymes from Claire's small intestine broke down the carbohydrates at a high rate. When Claire's small intestine released enzymes, they broke down the carbohydrates at a high rate.

Claire's small intestine can break down lipids, carbohydrates, and proteins, but the speed at which they do so differs. The enzymes in the small intestine are used to break down the foods that we eat into smaller, more easily digestible pieces.

The small intestine is where most of the digestion of carbohydrates, proteins, and fats occurs, and the digestive system is responsible for breaking down these macronutrients. Claire's small intestine breaks down carbohydrates at a high rate.

It's worth noting that the digestive enzymes in the small intestine are responsible for breaking down food, with carbohydrates and lipids being broken down the fastest.  In contrast, proteins are broken down more slowly compared to carbohydrates and lipids. Therefore, enzymes from Claire's small intestine broke down the carbohydrates at a high rate.

To overcome the limitation of unpredictability in studying tsunamis, the marine scientist can employ the following research methods:

By constructing a scaled-down model of a beach and subjecting it to controlled wave simulations, the scientist can observe and measure the impact of tsunamis on beach erosion. This allows for repeated experiments under controlled conditions, providing valuable insights into the behavior of tsunamis and their effects on coastal areas.

Since tsunamis are challenging to predict, the scientist can shift their focus to studying the effects of typhoons on beach erosion. Typhoons, or tropical cyclones, can generate powerful waves and storm surges that impact coastal regions. By investigating the relationship between typhoons and beach erosion, the scientist can gather relevant data and draw conclusions about the general processes and mechanisms involved in coastal erosion caused by extreme weather events.

Answer:

0.1% of energy

Explanation:

Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers absorb only 0.1 or 1%.

From the input of solar energy begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is dissipated in the environment.  

At each trophic level occurs an energy transfer to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

If wheat transferred 10% of the energy to mice, and of that 10% mice transferred 10% of the energy to hawk, then the percentage of energy transferred from the first trophic level to the third equals 0.1%.

10% (1st TL-2nd TL) / 10% (2nd TL - 3rd TL) = 0.1% (1stTL - 3rd TL)

TL = Trophic level

Lytic

Explanation:

Brainly deleted my answer? The correct answer is Lytic. The type of replication life cycle is Lytic.

Through internal metabolic heat production, heterotherms maintain high body temperatures.

Heterotherms are organisms with a body temperature control range that lies between that an ectotherm and an endotherm. Some endothermic ('warm-blooded') small mammals and birds may lower their metabolic rate during a particular season or even time of day, causing their body temperature to drop and enter a condition of torpor. This saves small animals, like hummingbirds and some rodents, the relatively expensive expense of keeping a steady body temperature when there is a lack of food or other unfavorable circumstances. Partial endothermy is another name for this tactic. On the other end of the spectrum, certain creatures that are typically thought of as ectothermic (or "cold-blooded") have the capacity to generate heat internally for brief durations, momentarily boosting their body temperature to enable activity when the surrounding environment is chilly. Many insects, including bumblebees, have been shown to shiver in cold weather in order to raise their body temperature enough to fly. We can refer to this as facultative endothermy.

The expected number of points scored is 2.6.

To find the expected number of points scored, we need to consider the probabilities of each scoring range and multiply them by the respective points. Since the distance is uniformly distributed between 0 and 10 inches, we can calculate the probabilities of each scoring range.

For 10 points (within 1 inch): The range is 0 to 1 inch, so the probability is 1/10 or 0.1.

For 5 points (between 1 and 3 inches): The range is 1 to 3 inches, so the probability is (3-1)/10 or 0.2.

For 3 points (between 3 and 5 inches): The range is 3 to 5 inches, so the probability is (5-3)/10 or 0.2.

The remaining probability (no points) is 0.5, as the shot is between 5 and 10 inches from the target.

Now, we can calculate the expected number of points:

Expected points = (10 points × 0.1) + (5 points × 0.2) + (3 points × 0.2)
Expected points = 1 + 1 + 0.6
Expected points = 2.6

Therefore, the expected number of points scored is 2.6.
