Disturbances inside Earth’s core cause earthquakes. The starting point of the disturbance is called the epicenter. Why does the amplitude of a seismic wave usually decrease as the wave moves away from the epicenter?
Answer:
The energy released by the earthquake spreads throughout a larger volume of Earth.
Explanation:
At farther distances the amplitude of the seismic waves decreases as the energy released by the earthquake spreads throughout a larger volume of Earth. Also with increasing distance from the earthquake, the waves are separated apart in time and dispersed because P, S, and surface waves travel at different speeds.

how many base pairs would a DNA segment of length 1.36mm have?
Answer:
4.0 million
Explanation:
The average length of a base pair (bp) is 340 pm (340 × 10^-12 m)
Length of DNA = Number of bp × length of each bp
1.36 × 10^-3 m = bp × 340 × 10^-12 m
bp = (1.36 × 10^ -3)/(340 × 10^-12) = 4.0 × 10^6
The DNA segment would contain 4.0 million bp.

Poison dart frogs live in the rainforest. They produce a poison by eating toxic fire ants. The only known predator is a snake, Liophis epinephelus. Which of the following factors is most likely a density-independent regulator of population growth of poison dart frogs in the rainforest? clear cutting the rainforest limited food source susceptibility to disease increase in population of Liophis epinephelus
Answer:
The correct answer is CLEAR CUTTING THE RAIN FOREST
Explanation:
The factors that affect the survival of living organisms can be divided into two major groups, which are density dependent and density independent factors. Density dependent factors refers to those factors that their impacts depend on the size of the population. Example of such factors are food availability, predation, migration and diseases.
Density independent factors on the other hand refers to those factors that affect population size regardless of their sizes. Examples of such factors are temperature, natural disasters, human activities, etc.
In the question given here, the clear cutting of the rain forest is brought about by human activity and is an example of density independent factor.
The answer is A. Clear cutting the rain forest because it is a human activity and that does not depend on the population size of a place.
Which would be an adaptation in a rain forest, but not in a desert?
A. Ability to store water for a long time
B. Better eyes for hunting prey
C. Skin that blends in with green plants
D. Very small leaves to trap water
ANSWER:
The correct option is C: Skin that blends with green plants. Most animals in rain forests are green so that they can camouflage and appear like plants.
EXPLANATION:
Adaptation is the way in which animals survive in different climatic conditions and different regions. In rain forests, to protect themselves and to find food, most animals are green in colour. This prevents the animals from being spotted easily and therefore they are protected from hunters and other animals that eat them. This way, the animals can also find their prey and catch it easily.Answer: c <3

A skeletal muscle is a composition of several components bundled one into the other. At which structural level in the muscle does contraction occur
to bring about contraction in the whole muscle?
Answer:
The correct answer will be- myofilamants-actin and myosin.
Explanation:
The skeletal muscle is made up of the muscle fibers which are cylindrical cells enclosed by layers. The muscle cell is divided into smaller units, the smallest of which is myofilaments.
The myofilaments are composed of the thin filaments called actin and thick filaments called myosin which together forms the functional unit of a muscle known as the sarcomere. The muscle contraction takes place due to the sliding of these actin and myosin over each other as a result of the signals arrived from the CNS.
Thus, myofilaments-actin and myosin is the correct answer.

Which of the following best helps scientists determine the order in which a species evolved? (2 points)
Type of fossil
Geographic location of the fossil
Location of the fossil in Earth's layers
Species of the fossil
The location of the fossil in Earth's layers helps scientists determine the order in which a species evolved.
Explanation:The correct answer is Location of the fossil in Earth's layers. The study of fossils and their position in the rock layers, known as stratigraphy, can help scientists determine the relative age of different fossils and the order in which species evolved. By examining the layers of rock, scientists can identify the sequence of fossil species, with older fossils found in lower layers and more recent fossils found in higher layers.
The option that best helps scientists determine the order in which a species evolved is the location of the fossil in Earth's layers. This method is central to the field of stratigraphy, which studies the layers of sedimentary rock to establish a timeline for events. The principle of superposition is key in this field; it states that in undisturbed layers of rock, the oldest layers are at the bottom, and each subsequent layer is younger than the one beneath it. So, fossils found in deeper layers are typically older than those found in layers closer to the surface.

which of these practices does the most to decrease the amount of water needed to farm?
A-drip irrigation
B-crop rotation
C-cash crops
D-no-trill farming?
The practice that does the most to decrease the amount of water needed to farm is (A) drip irrigation.
What is Drip irrigation?Drip irrigation is a type of irrigation system that delivers water directly to the roots of plants, drop by drop, through a network of tubes and emitters.
This system uses water much more efficiently than traditional methods of irrigation, such as flood irrigation or sprinkler systems, because it delivers water precisely where it is needed and minimizes evaporation and runoff.
Crop rotation, cash crops, and no-till farming are also practices that can help to conserve water in agriculture, but they do not have as significant an impact on water use as drip irrigation.
Crop rotation involves planting different crops in a specific sequence to help maintain soil health and fertility, while cash crops are crops that are grown primarily for sale rather than for subsistence. No-till farming involves leaving the soil undisturbed between crops to help reduce erosion and conserve soil moisture.
Overall, while each of these practices can contribute to water conservation in agriculture, drip irrigation is the most effective in reducing the amount of water needed to farm.

Which best describes how an organism’s niche is determined
Answer:
The answer is....
Explanation:
An organism's habitat and ability to reproduce determine its niche.
An organism's niche is determined by several factors, primarily its competition for resources, the features of its physical and geographic environment, and its unique nutritional and reproductive strategies.
Explanation:An organism's niche in an ecosystem is determined by several factors tied to both its unique characteristics and the properties of the environment. These factors range from the resources it consumes, to its interactions with other species, to the physical features of its habitat.
Firstly, competition for resources such as food, water, sunlight, and mineral nutrients plays a significant role in determining an organism's niche, due to the restrictions imposed by the principle of Competitive Exclusion. This principle asserts that two species cannot occupy the same niche in a habitat, implying that they can't compete for all the same resources and still coexist in the same community.
Moreover, the components of an organism's physical and geographic environment, such as the habitat's climate, topography, and available species, are also essential determinants of its niche. This is because they significantly impact which organisms can exist within a specific area.
Lastly, an organism's nutritional and reproductive strategies add to the determination of its niche. These strategies depend upon the type of organism, its nutritional requirements, and the type of habitat it inhabits.
