Answer:
As we move to higher Trophic levels, we will, generally speaking, see larger animals. And yet, moving to higher trophic levels, these larger animals need to live on smaller energy production from the next trophic level down. As a result, there will usually be fewer animals at higher trophic levels.

Water bends light. This type of bending is called refraction. The drawing tool shows a penny submerged in water, but only part of the path of the light ray is shown. How could the light ray bend as it enters and leaves the water so that you can see the penny at position B? Draw the missing parts of the light ray so the penny is visible at position B.
Water makes the penny visible by bending the light rays towards the normal.
What is refraction of light?Refraction is the bending of light rays as it crosses the boundary of media of different densities.
The ability of water to to bend light is employed in making a penny visible when water is added to container container a penny which was not visible initially.
Therefore, water makes the penny visible by bending the light rays towards the normal.

Which function involves the circulatory system working with the respiratory system?
A. Lowering body temperature
B. Enabling cellular respiration
C. Stopping bacterial infection
D. Maintaining liver function
The function involves the circulatory system working with the respiratory system is Enabling cellular respiration. Thus, option "B" is correct.
What are circulatory and Respiratory system?Respiratory system is a set of organs which help in the exchange of gases in the body. They bring oxygen from outside into the body and release carbon dioxide from inside the body to the outside world. The exchange of the gases takes place at the alveolar site (or gills in aquatic animals).
The circulatory system then carries this oxygen (mixed in blood) from gas exchange site to all the cells of the body. In addition, it also brings carbon dioxide (waste product of cellular respiration) from all the cells to the gas exchange site (respiratory system).
Thus, option "B" is correct.

How would our interaction with the suns energy differ if our magnetosphere disappeared?
Answer:
Enveloping our planet and protecting us from the fury of the Sun is a giant bubble of magnetism called the magnetosphere. It deflects most of the solar material sweeping towards us from our star at 1 million miles per hour or more. Without the magnetosphere, the relentless action of these solar particles could strip the Earth of its protective layers, which shield us from the Sun’s ultraviolet radiation. It’s clear that this magnetic bubble was key to helping Earth develop into a habitable planet.

Answer:

Explanation:
. Conduction of heat takes place only in .......
a Solids
b) Liquids
c) Gaseous
d) air
Answer:
Option A: Solids
Explanation:
Due to the fact that heat is transported from a hotter body to a cooler body when two objects are kept in thermal contact, conduction only occurs in solids and not in liquids or gases. Conduction is the term for this mechanism, which uses the same body temperature. When two bodies remain together during conduction to transfer heat In order to transmit heat energy quickly and more efficiently, the molecules of both entities vibrate and collide with one another. Since solids have compactly packed molecules, this allows the molecules to vibrate more and transfer heat more effectively than liquids and gases. When molecules in close proximity to one another clash, energy is transferred. Due to the molecules' near closeness and, in the case of crystals, their clearly defined structure, this occurs very readily in a solid. A few things alter when heat transport in liquids and gases is taken into account. The molecules are not as close together, and gravity has a particular, confusing influence. Heat is transferred through collisions of nearby particles in a process known as convection. The metal surface particles are transmitting heat to the liquid through conduction at the metal-water interface if convection is occurring between a solid that is hotter than the liquid adjacent to it, such as a pan on the stove. But when that occurs, the water's density begins to alter. The water molecules at the surface move faster, contain more energy, and occupy more space per mass (they are less dense). Because water molecules may pass one another and gravity makes this easier, the less dense water near the metal surface is replaced by the more dense water above it. Natural convection is the mechanism through which a liquid or gas moves in this manner as a result of variations in density. Conduction is no longer possible unless you can prevent the effect of fluid density on the flow of gases or liquids. Fundamentally, in both liquids and gases as well as solids, molecules continue to exchange energy through collisions. Conduction, however, performs this considerably more effectively in liquids at the metal-liquid contact and less so as you travel away from the interface and upward through the liquid. Convection is the movement of particles to transfer heat.
Bottom Line: Conduction may occur in gases and liquids, but you must be able to reduce the impact of gravity. These are known as "stagnant fluids." Convection is the term used to describe fluid movement caused by density variations when they are not prevented.

two different groups of scientists predicted regional climate changes for California and came up with contradictory (different and opposing) results. Explain how this could happen...
Two different groups of scientists came up with contradictory regional climate changes as there are many climate zones in California based on latitude, altitude, and distance from the coast.
What climate zones are in California?Depending on latitude, height, and distance from the coast, the climate in California varies greatly, ranging from sweltering desert to alpine tundra. The coastal areas of California, the foothills of the Sierra Nevada, and a large portion of the Central Valley have a Mediterranean climate, which features warmer, drier summers and cooler, wetter winters. In coastal places, the influence of the ocean often moderates temperature extremes, resulting in milder winters and noticeably cooler summers.
The reason for this is the geographic location of the state, which stretches roughly between 32° and 42° north latitude.
Unique topographical features as well as a variety of bedrock and soil types have been produced as a result of glaciation, sedimentary and volcanic deposits, movement along fault zones, the uplift of subsurface rock and sediment layers, and progressive erosion. The topography and geography of the state have produced several local climates.
