Melting of glaciers and ice caps.

Explanation:

Global warming increases greenhouse gasses increasing heat, obvi. So that will cause the glaciers to melt. and with out glaciers there is no cold water without could water there is no convection current without convection current there are isnoway to move nutrients.

One of the possible consequences of decreasing air quality resulting from global warming is melting of glaciers and polar ice caps.

representative democracy

Explanation:

Democracy can be defined as a government of the people, by the people and for the people.

There are two (2) main types of democracy and these include;

I. Representative democracy: it's also known as indirect democracy and can be defined as a form of government which typically involves the process of having the citizens of a particular country vote to elect representatives (political leaders) to enact laws, create policies and make decisions on their behalf.

Hence, representative democracy is a type of democracy where citizens elect leaders to represent them in government.

II. Direct democracy: it can be defined as a process which typically involves the candidates voting for their preferred choice. Thus, their choices are reflected directly on the subject matter.

Generally, the type of government in which legislators such as senators or house of representative members are found is known as a democracy and they are saddled with the responsibility of enacting or making laws.

A snake moves from a sunny area to a shady area to cool down.

Homeostasis is a process to regulate and maintain the temperature and internal body environment. A snake moving from a sunny to a shady region to cool down is behavioral homeostasis. Thus, option C is correct.

Homeostasis has been defined as the process that maintains the relative equilibrium temperature of an internal environment so as to regulate physiological processes.  They are essential for maintaining optimal functioning.

A snake shows behavioral homeostasis when it moves from a sunny area to a shade region so as to cool its body temperature. The mode of temperature regulation is behavioral homeostasis which regulates the body temperature.

There is less need for canines and incisors in herbivorous animals as it is mainly used to tear the flesh. Herbivorous animals mainly have developed premolars and molars to grind the grass properly. Horse has small incisors and canines but wide premolars and molars.

Teeth are usually covered with a hard substance called enamel which helps them to be strong. Its color is slightly yellow.

Teeth are of four types. Namely:

Canines are well developed in carnivorous animals as they need to tear the flesh. But in the case of herbivores, these are comparatively smaller.

Thus, an animal jaw that has small incisors and canines but wide premolars and molars may belong to a horse.

Explanation:

cellular functions depend on numerous protien-coding RNAs and the RNA -binding proteins associated.

Answer:

C it is used to transfer info to the ribosome

Explanation:

The ribosome is responsible for the production of proteins, so when mRNA enters a cell, the code is sent to the ribosome so that it can begin constructing the proteins.

The reason of differences in the amino acids sequences with respect to the  proteins in different organisms should be because of the sequence.

The protein should be comprise of the polypeptide backbone along with the chains that are attached.

Each and every type of the protein should differed in the form of sequence and the no of amino acids.

Also, it does have the sequence of the chemically distinct side chains.

Therefore, in this way it have the difference.

Answer:

The Earth can be divided into 5 main layers according to their physical properties: the lithosphere (most superficial layer of the Earth: rigid and cold), the asthenosphere (Second most superficial layer of the Earth: soft and ductile), the mesosphere or lower mantle ( Middle layer of the Earth: rigid and hot, able to flow gradually), the outer core (Second innermost layer of the Earth: liquid) and the inner core (innermost layer of the Earth: solid). The flow of heat inside the Earth will depend on the temperature and the characteristics of the material. The crust behaves like a solid and has relatively low temperatures. The mantle behaves like a fluid and since convection is much more efficient in this case, that is the main means of transport, even though the relatively high temperatures make it possible for energy to also be transported by means of radiation.

Explanation:

As you descend into the Earth's interior, the temperature, pressure, and density of the rocks gradually increase. The Earth can be divided into five main regions based on its physical properties (temperature and pressure) and according to its mechanical resistance: lithosphere the chemical composition of this layer is notably different, it also acts as a unit that shows a rigid behavior (not can be bent), mainly because it is cold and consequently resistant, asthenosphere located in the upper mantle (at a depth of about 660 km), there is a comparatively plastic soft layer, mesosphere (lower mantle) more rigid layer and it is because as the pressure increases, it counteracts the effects of the higher temperature and the resistance of the rocks increases gradually with depth. Despite their resistance, the rocks of the mesosphere are still very hot and are able to flow in a very gradual way, the outer core is a 2270 km thick liquid layer. The convective currents of iron in this area are those that generate the Earth's magnetic field and the inner core of the material is more resistant than the outer core (due to the enormous pressure to which it is subjected) and behaves like a solid. When penetrating the crust of the Earth a change in temperature is observed, in general it increases; this variation in temperature with depth is called a geothermal gradient. The heat flux on the Earth's surface is calculated as the product of the geothermal gradient and the thermal conductivity of the rocks, these two parameters being directly determined. The Earth is basically made up of three concentric layers: the innermost core has a composition of cast iron at a temperature of over 4,000 ºC; the mantle that is the intermediate layer formed by iron and magnesium silicates and its temperature varies from 4,000 ºC in its contact with the core to 800-1000 ºC of its outer surface that contacts the crust that is the most superficial layer and visible by man. This crust has a variable thickness of 5 to 35 km and is made up of aluminum and magnesium silicates, its temperature varying between 800-1000 ºC of contact with the mantle and 15-20 ºC of the surface that we know.

C. They have a continental rise.

Explanation:

A passive continental margin has a continental rise.

A passive margin is a transition between the continental and oceanic lithosphere that was originally generated by rifting. It is not associated with a plate boundary.

Sedimentation generates a passive edge over an ancient rift, which is now characterized by transitional lithosphere. New ocean basins are formed as a result of continental rifting.
