These differences accumulate over generations, resulting in changes within the population. Over time, populations can split or branch off into new species. These processes, collectively known as evolution, are responsible for the many diverse life forms seen in the world.

Shell-builders use calcium carbonate molecules (CaCO3) to build their shells. Which of the choices above could be a source for t
Fudgin [204]

Answer:

The question is incomplete, the correct question is;

Shell-builders use calcium carbonate molecules (CaCO3) to build their shells. Which of the following choices could be a source for the carbon atoms in the calcium carbonate (CaCO3) molecules?

respiration by organisms such as plants, animals and microbes

burning coal

calcium ions

car exhaust

wildfires

Answer is all of the above options except calcium ions.

The source for the carbon atoms in the calcium carbonate (CaCO3) molecules include respiration by organisms such as plants, animals and microbes , burning coal , car exhaust  and wildfires.

Explanation:

Shell-builders (coral, oysters, lobsters, sea urchins, phytoplankton) utilize calcium carbonate molecules (CaCO3) to build their shells. The respiration process by organisms such as plants, animals and microbes, burning of fossil fuels, vehicle exhaust, wild fire etc produces carbon dioxide (CO2) and release it into the atmosphere. Oceans absorb carbon dioxide in the air by diffusing and dissolving it into the surface water. The amount of CO2 that dissolved in the water depends on concentrations of CO2, temperature of the water, wind, etc.

Phytoplanktons (microscopic, one-celled organisms) also bring carbon into the ocean from the air through photosynthesis, where they convert the carbon dioxide and water into glucose and other carbon compounds. These carbon compounds are consumed by the marine organisms and some carbon eventually ends up in deep seafloor sediments. The other processes which involved in the transfer of carbon from the air into deep seafloor sediments include photosynthesis , decomposition , waste products, etc.

The CO2 dissolved in the ocean combines with water molecules to produce carbonate (CO3-) ions, which then combine with calcium ions in the seawater to form calcium carbonate (CaCO3). This calcium carbonate is used by shell building organisms to build their shells, plates, inner skeletons etc.

In this course, you will learn about hormones and their effects on cells. Certain hormones bind to receptors at the plasma membr
vova2212 [387]

Cellular communication is the function of the plasma membrane that allows it to respond to certain stimuli from outside the cell and hormones to bind to receptors.

<h3>What is plasma membrane?</h3>

It is a double layer of lipids that covers and delimits the cells, serving as a border between the inside and the outside of the cell, and also allowing a physicochemical balance.

<h3>Characteristics of plasma membrane</h3>

Enables the development of compartments; allows or rejects the entry and/or exit of particles; acts as a mechanical defense; and reacts to external signals and stimuli.

It reacts and transmits information inside the cell, starting certain biochemical processes: cell division, cell movement or the segregation of biochemical substances.

Therefore, we can conclude that the main characteristic of the plasma membrane, that is, its ability to allow or reject the entry of certain molecules into the cell.
