Answer:
They interact by the upper mantle transferring energy by conduction to the core assisting in the softening of the rock layer which leads to radiation.
Explanation:
Convection currents coming from the core and mantel are believed to the main cause of the interaction. As these currents travel up and down the curst and mantle boundary and this creates the plates to move freely forming a conveyor belt. The core of the earth creates this convective current to rise up due to the heat and pressure. The hot molten rocks in the mantle eventually cool and the cycle of rising and sinking takes place.In an ecosystem, a wide range of organisms coexist. In a pond ecosystem, one can find amoebae, bacteria, green algae, and fish. Which of the
following is the best conclusion one can make regarding the genetic diversity of these organisms?
Green algae will have the greatest genetic diversity because they are photosynthetic and do not depend on other organisms to survive.
Fish will have the greatest genetic diversity because they receive genetic material from a male and female source.
Bacteria will have the greatest genetic diversity because their high reproductive rate ensures that some will survive.
Amoebae will have the greatest genetic diversity because their genetic makeup allows them to survive in many environments.

Explanation:
Answer:
The correct answer would be "Fish will have the greatest genetic diversity because they receive genetic material from a male and female source".
Genetic diversity is defined as the variation in the total amount of genetic information among the individual of the population.
In sexually reproducing population, genetic diversity is present in high amount as compared to asexually reproducing population.
It is because of two reasons:
The genetic make of an individual is determined by 2 parents (father and mother).
The event of crossing over takes place during formation of gametes.
Together, they lead to the development of new combinations of alleles in an offspring which is different from both the parents.
Thus, fish would have the highest genetic diversity in their population.

which term names part of the peripheral nerves system A spinal cord B brain C sensors
Answer:
[tex]\boxed {\boxed {\sf C. \ Sensors}}[/tex]
Explanation:
There are two divisions of the nervous system: the central and peripheral.
The central nervous system (CNS) is made up of the brain and spinal cord. This section processes information gathered from the sensory organs.
The peripheral nervous system (PNS) is divided into the autonomic and somatic, with different functions. Regardless of the subdivision, the PNS is made up of all the nerves and sensory receptors. The nerves are connected to the brain and spinal cord, which allows them to pass information from the PNS (where it is gathered ) to the CNS (where it is processed).
So, the spinal cord (choice A) and brain (choice B) are parts of the central nervous system, not peripheral. The correct answer must be C. sensors

O D. (a cosc, b sinC)
Answer:c
Explanation:because cosin of b is c
(a cosc, b sinC) pairs represents the vertex A in this diagram. Hence option D is correct.
What is Vertex ?In geometry, a vertex (in plural form: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.
The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight sides meeting at one place.
In a polygon, a vertex is called "convex" if the internal angle of the polygon is less than π radians otherwise, it is called concave.
Hence option D is correct.

n the northern United States where snow and ice create dangerous road conditions in the winter, the Department of Public Transportation often salt roads, which encourages melting. How could salting the roads have and impact on the plant life that live on the edge of the road?
Plant cells will lose water due to osmosis.
Plant cells will gain water due to osmosis.
Plant cells will use the salt to grow taller.
There would be no impact.
Answer:
Plant cells will lose water due to osmosis
Explanation:
Osmosis uses a concentration gradient. Water travels from areas of high concentration to low concentration. The salted road has low water concentration while the plants near the edge have a higher water concentration. The water will leave the plants and go to the salted road. Using common sense, if you sprinkle salt on a snail, it dehydrates and dies. Same thing happens here. The salt sucks the water out.

What is the direct cause of most earthquakes?
O Gravitational pull on bedrock by the moon
O deposition of sediment in lakes and oceans
O movement of bedrock along a fault line
O heat exchange betwęen the crust and the atmosphere
Answer:
Pretty sure it's C or B? Most likely C.
The direct cause of most earthquakes is the movement of bedrock along a fault line. Earthquakes occur when energy stored in the Earth's crust is released suddenly, causing the ground to shake. Hence option D is correct.
What is an earthquake?An earthquake is a sudden and rapid shaking of the Earth's crust caused by the breaking and shifting of rock beneath the Earth's surface. The Earth's crust is made up of tectonic plates that constantly move and interact with each other.
When these plates move against each other, they create pressure that builds up over time until the rock breaks, causing an earthquake.
This energy is released when two blocks of rock, called tectonic plates, move relative to each other along a fault.
The blocks may become stuck, and as the pressure builds up, they may suddenly slip, releasing energy in the form of seismic waves that cause the ground to shake.
The intensity and magnitude of an earthquake depend on the amount of energy released and the distance from the epicenter.
While other factors such as volcanic activity, landslides, or human activities can also cause earthquakes, movement along a fault line remains the primary cause.
Hence option D is correct.

how does mangrove planting reduces impact of climate change
Answer:
By slowing down the movement of water and catching sediment, mangroves help reduce the impacts of storm waves and flooding. mangroves also prevent greenhouse gasses which helps climate change.
Explanation:
Answer:
Besides protecting shorelines from extreme weather and providing fish a safe place to breed, mangroves could play a big role in trapping climate-changing carbon emissions, something that has so far been largely overlooked, they said. As mangroves are cleared at a rate three to five times faster than other forests, according to UNEP estimates, those losses are particularly felt in developing countries where most mangroves are located, including Bangladesh, India, Pakistan, Sri Lanka, Kenya, Senegal, West Bengal, Vietnam and Sumatra. Like other plants, mangroves take carbon dioxide from the air as they photosynthesize. They use this carbon dioxide to produce more leaves. As a result, this carbon gets locked in the leaves instead of the air. This is why plant communities like forests and grasslands are called “carbon sinks". As leaves fall from trees, they decompose and the trapped carbon slowly drains back into the atmosphere. Mangrove leaves drop into the water. Lower oxygen levels in that water means that leaves decay more slowly than they would in air. The leaves also serve as a primary food source for a variety of animals like worms, shrimp, fish and crabs. These animals transport that carbon to deeper water. Deeper still if they are eaten by larger animals. When they die, they sink to the bottom where their carbon remains trapped indefinitely.
