Answer:
The Cell Theory has greatly impacted later scientific discoveries, even the modern science. It proves that every living thing in the world is made up of one or more cells. It impacted scientific discoveries because now scientists can find out more about organisms that they couldn't have if they didn't know about cells. Because of this, scientists can now understand and identify various organisms.
Answer:
The correct answer is ''proteins.''
Explanation:
Transport phenomena are essential in living beings, either to carry a hydrophobic molecule through an aqueous medium (transport of oxygen or lipids through the blood) or to transport polar molecules through hydrophobic barriers (transport through the cell membrane). Biological transporters are always proteins. Proteins are capable of carrying out specific functions such as the selective transport of molecules, or certain enzymatic reactions, among others. Membrane proteins can be peripheral or partially or totally integrated into the membrane, being, generally, globular or fibrous. Its activity is essential for the maintenance of transmembrane gradients. Thanks to membrane proteins, the exchange of molecules such as nutrients or waste products takes place, as well as the reception of external signals. Among its functions are channel-forming: Integral proteins arranged in the membrane in such a way that they give rise to the formation of a pore or channel, usually hydrophilic. These pores or channels allow the entry and exit of certain substances from the cell.
Explanation:
Hey there!!
As we know that,
weight of a body = m.g
Where, "m" is mass of an object and "g" acceleration due to gravity.
which implies,
w is directly proportional to m and g.
As the mass remain constant it donot change but g always varies according to the places.
So, The weight of an object is affected by acceleration due to gravity as it varies from place to place.

Answer:
Net primary productivity = 24,500 kcal/m²
Explanation:
Given:
Gross primary productivity = 38,000 kcal/m²
Respiration amount = 13,500 kcal/m²
Find:
Net primary productivity
Computation:
Net primary productivity = Gross primary productivity - Respiration amount
Net primary productivity = 38,000 - 13,500
Net primary productivity = 24,500 kcal/m²
