Explanation:

Conduction, convection and radiation are the modes of heat transfer:

Conduction:

Microscopic level of heat transfer

Also called as thermal diffusion(takes place due to atomic vibrations) and is highly invisible

Primarily occurs in solid-solid systems and stagnant liquids

Convection:

Macroscopic level of heat transfer

Primary occurs in fluids(involves bulk movement of fluids)

2 types of convection are possible — with external source of energy (forced convection) and without external source of energy (free convection)

Radiation:

Transfer occurs through electromagnetic waves

No medium is required unlike conduction and convection. Radiation can occur even in vacuum.

These are different processes of transferring energy from one place to another.

Radiation is the sunlight and (heat). It travels as electromagnetic wave and does not need matter to transfer energy. Hence radiation is the only mode of transferring energy in vaccuum, for example, light of visible and invisible wavelengths reaches from the sun and other stars as electromagnetic radiaton. Human body emits heat wave as radiation.

Convection and conduction refers to energy transfer through the motion of matter. The difference is how the molecules of matter move during the energy transfer.

Convection is that mode of energy transfer when matter also transfer from one place to another during energy transfer. Molecules of liquids and gases can move. So convection occurs in liquids and gases. It is visible when water is boiled on a gas burner.

Molecules of solids are too tightly bound to move. They vibrate about some average positions in space. Conduction is that mode of energy transfer when matter on average is not transferred from one place to another. Propagation of sound through solid wall is an example.

Answer:

Most people believe that drinking milk can soothe heartburn.

Explanation:

Pseudoscience refers to practices and beliefs that are believed to be scientific but in actuality, do not follow any known scientific method. Even after it has been logically proven that these practices have no scientific backing people continue to believe in them because through confirmation bias, they believe that they work.

True science is evidence and research-based. Pseudoscience as seen in the last option is just based on belief.

Answer:

Simply put, the property of electron affinity refers to the relative amount of love that a material has for electrons. If atoms of a material have a high electron affinity, then that material will have a relatively high love for electrons. This property of electron affinity will be of utmost importance as we explore one of the most common methods of charging - triboelectic charging, also known as charging by friction or rubbing.

Suppose that a rubber balloon is rubbed with a sample of animal fur. During the rubbing process, the atoms of the rubber are forced into close proximity with the atoms of the animal fur. The electron clouds of the two types of atoms are pressed together and are brought closer to the nuclei of the other atoms. The protons in the atoms of one material begin to interact with the electrons present on the other material

Answer:

Male reproductive organ is responsible for sexual function.

Explanation:

Male reproductive organ produces sperm which combines with eggs of female reproductive organ produces fertile offspring. The male reproductive system is mostly located outside of the body. The external organs include the penis, scrotum and testicles while on the other hand, internal organs include the vas deferens, prostate and urethra. The male reproductive system is responsible for sexual function, as well as removal of waste material from the body.

The destruction of tropical forests can affect the balance of gases in the Earth's atmosphere increasing carbon dioxide and decreasing oxygen.

Deforestation by fire contributes significantly to the increase in air pollution. The world today faces a series of environmental problems, the main ones being the deforestation of natural forests and air pollution, which causes the emission of CO2 (carbon dioxide) into the atmosphere.

With this information, we can conclude that the destruction of tropical forests can affect the balance of gases in the Earth's atmosphere increasing carbon dioxide and decreasing oxygen.

heterogeneous - possessing different alleles for a trait. homologous - possessing identical alleles for a trait.

Enzyme B stays effective at higher temperatures than enzyme A. Therefore, option (C) is correct.

From the graph, it can be observed that Enzyme B remains effective at higher temperatures, while Enzyme A is less effective at higher temperatures. As the temperature increases, Enzyme A's activity decreases and is less efficient in converting the substrate into product, while Enzyme B remains active at higher temperatures and converts more substrate into product.

Therefore, the conclusion that can be drawn from the graph is that Enzyme B stays effective at higher temperatures than Enzyme A.

Answer:

Golgi complex and Nucleus.

Explanation:

In the diagram, A part is refers to Golgi complex whereas B part is refers to nucleus. Nucleus controls different activities of the cell while on the other hand, Golgi complex produces proteins and lipid molecules that can be used for in other places inside and outside of the cell. The Golgi complex is a cell organelle which is also called Golgi apparatus and Golgi body.

Answer:

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

Answer:

a) Las raíces superficiales y extensas

c) El cuerpo carnoso de las plantas

d) Las hojas modificadas en forma de espina

Explanation:

En biología, una adaptación refiere al proceso de cambio evolutivo mediante el cual los organismos de una especie/taxón hacen frente a determinadas condiciones ambientales. Las plantas han desarrollado diferentes adaptaciones en ambientes desérticos a fin de evitar al máximo la pérdida de agua, el factor más limitante en este tipo de ambientes. Las plantas capaces de soportar largos periodos de sequías se denominan xerófitas. En primer lugar, además de servir como una buena defensa contra herbívoros, las hojas en forma de espina le permiten a una planta almacenar agua durante los períodos de precipitaciones. En segundo lugar, las raíces de plantas desérticas pueden disponerse superficialmente con el objetivo de absorber la mayor cantidad de agua posible. En tercer lugar, las plantas suculentas o crasas son aquellas que tienen tejidos carnosos los cuales pueden almacenar agua en sus hojas, tallos o raíces. Durante los periodos de lluvia leve, las suculentas almacenan grandes cantidades de agua para sobrevivir durante la temporada seca (incluso existen especies vegetales que sobreviven solamente durante la temporada húmeda y producen semillas que toleran la temporada seca).

Answer:

1- substitution.

2- neutral.

Explanation:

The change in the genetic sequence of the organisms known as mutation. Mutations might be sudden and heritable in nature. spontaneous mutation and induced mutation are types of mutation.

A change that causes a change in single base pair of a gene sequence is called substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. Thus T has been substituted by G.

Mutation can be beneficial, detrimental or neutral. The neutral mutation is that does not affect the physical change. Both GTT and GTG code for the same amino acid so it would be neutral.

During the winter, snowshoe hares are white, which helps them blend in with the snow. When the seasons change to spring and summer, snowshoe hares turn a reddish-brown.

Answer:

This event led to the breaking away of a part of earth and the part was held on by earth’s gravity and this part became the moon.

Explanation:

The formation of moon was after the formation of the earth. In the initial years of the formation of earth it was affected by several asteroid hits and comets. Small planets referred to as planetesimals  also kept continuously affecting the earth. Before 4.5 billion years ago a planetesimal which was about the size of Mars hit earth.

This hit led to the breaking away of a part of earth. The part which was sent to space by the hit was caught by the gravity of the earth and the part started orbiting around the earth. The similarity of the rocks in moon to that of earth is attributed to the fact that moon was actually formed from earth.

The moon and earth keeps influencing each other. The moon’s effect reduced the speed of earth’s rotation and the moon keeps moving away from the earth due to the influence of earth.

Answer:Molten rock broke off from Earth following the impact. The rock coalesced (gathered) into a ball, which formed the Moon.

Answer:

The correct answer is - reuptake of the neurotransmitter molecule into the axon through a membrane transporter.

Explanation:

The action of a neurotransmitter at the postsynaptic cell or postsynaptic potentials is terminated by any of these mechanisms that are enzymatic degradation, diffusion or reuptake into the presynaptic cell by specific transporters.

After the desired biological response by postsynaptic potentials, in order to avoid over stimulation or termination of the postsynaptic potentials the neurotransmitter is taken back into the axon through a membrane transporter. This mechanism is to maintain a balance.
