Answer:
Sea urchins use five-part jawlike structures to scrape algae from rocks. Sea lilies use tube feet along their arms to capture floating plankton. Sea cucumbers move like bulldozers across the ocean floor, taking in sand and detritus. Sea stars usually feed on mollusks such as clams and mussels.
Explanation:
How is Continental crust and Oceanic crust different in terms of rock composition?
Answer:Continental crust is broadly granitic in composition and, with a density of about 2.7 grams per cubic cm, is somewhat lighter than oceanic crust, which is basaltic (i.e., richer in iron and magnesium than granite) in composition and has a density of about 2.9 to 3 grams per cubic cm.

Answer:
A} the sun
Explanation:
The sun is the greatest and heavier then the other planet
Most of the mass in the solar system is contained in the Sun. Option A is correct.
The majority of the solar system’s mass lies between 99.8% and 99.9% in the Sun. The remainder is distributed among the planets, their satellites, comets, asteroids, and the surrounding interstellar dust and gas.
The solar system's gravitational field is dominated by the sun, which makes up 99.85%. The planets, condensed from the same disc of matter that created the sun, make up 0.135%.
The sun is located at the center of the solar system and is the largest object in the Solar System by far. It is 109 times the size of the Earth. About one million Earths would fit inside the sun.
Therefore, the correct option is option A.

The statement best summarizes the role of households in the flow of goods is households exchange money for products in resource markets. Thus, option C is correct.
Who are the consumers among households?The final consumers of the goods and services produced by the businesses are the households. According to their tastes and preferences, they create demand in the market. The businesses supplied and produced goods in response to customer demand. As a result, a nation's production line is determined by its households.
To run a business, workers are needed, and business owners, managers, and employees also have families. In return for labor, the business pays wages, which increase household income.
Therefore, A company's output may fall somewhere in the middle of these two ideas. A landscaping company, for instance, might offer a homeowner a service and sell them a tree as a product.

how does geographic isolation cause an increase in differences between two groups
Answer:
What was once a continuous population is divided into two or more smaller populations. This can occur when rivers change course, mountains rise, continents drift, or organisms migrate. The geographic barrier isn't necessarily a physical barrier that separates two or more groups of organisms. It might just be unfavorable habitat between the two populations that keeps them from mating with one another.

in the dihybrid cross for pea plants shown below, ris dominant for round peas, ris recessive for wrinkled peas, y is dominant for yellow peas, and y is recessive for green peas. a student could accurately make which statements about the offspring of this cross
A. There is a 50% chance of having round, yellow peas
B. There is no chance of having round, yellow peas
C. There is a 100% chance of having round, green peas
D. There is no chance of having any wrinkled, green peas
Answer:
D, there's no chance of having any wrinkled, green peas
In the given scenario, there is no chance of having any wrinkled, green peas. The correct option is D.
What is dominant and recessive characters?When a trait has two different forms at the gene level, dominant and recessive traits exist. The dominant trait is the trait that first appears or is visibly expressed in the organism.
The recessive trait is one that is present at the gene level but is masked and does not manifest itself in the organism.
A trait that is expressed only when the genotype is homozygous; a trait that is masked by other inherited traits but persists in a population among heterozygous genotypes.
Dominant inheritance refers to the inheritance of traits that are typically passed vertically from parent to child, with both the parent and the child affected by the trait or disorder associated with that gene.
In the given image, there is no recessive alleles, all are in combination with the dominant one, so it is not possible to have wrinkled, green peas.
Thus, the correct option is D.

What are convergent boundaries?
Answer:
Explanation:
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.
Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]
Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence

Jonas and his family are moving to another part of the city. As Jonas, his brother, and his Dad were driving one of the trucks filled with furniture to their new home, Jonas noticed that the truck seemed to take longer to stop now that it was heavier with the furniture. Which Newton's Law explains why this happens?
Answer:
Newton's 2nd Law of Motion
Explanation:
A force applied to an object at rest causes it to accelerate in the direction of the force. It is easier for the empty truck to stop than a full truck, because the full truck has more mass than the empty one.
This phenomenon is explained by the law of inertia i.e. the first law of Newton.
What is Newtons's first law?According to Newton's first law, unless pushed to alter its motion and direction by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line. It is also known as the law of inertia.
A body's inertia is a quality that makes it resist changes to its state. The amount of a body's inertia in translational motion is determined by its mass. A heavier body's consistent motion or state of rest is challenging to alter, and the opposite is true for lighter bodies. This is why the truck filled with furniture takes longer to stop.
Thus, when Jonas noticed that the truck seemed to take longer to stop now that it was heavier with the furniture. It is explained by the first law of motion (law of inertia).

Answer:
Water, up
Explanation:
In the process of movement water in the diffusion of water the net movement of water goes from higher concentration to the low concentration area. The movement of water move form one side to other side until it reaches an equilibrium and the level of water on the other side goes up.
Hence, the water molecule will move from from side B to side A until it reaches equilibrium and the water level on side A goes up.

How did Charles Darwin use the concept of density dependent factors in his Theory of Evolution
Answer:
Density-dependent factors are defined as the biological factors which are utilized by the population as a resource for example- food and shelter. Charles Darwin uses the concept of density-dependent factors in his Theory of Evolution to show how it affects population growth and mortality.
Charles Darwin used factors like competition, predation, and parasitism in his Theory of Evolution. He explained that habitats are limited by space and resource availability, and only the fittest organism will survive the competition.
Predator-prey relationships create density-dependent limiting factors and balance the ecosystem with limited organisms. If predators will increase in an ecosystem it will decrease the population of prey and after a certain time there will be a shortage of food as they are limited resources.
