Vestigial structures are often homologous to structures that are functioning normally in other species. Therefore, vestigial structures can be considered the evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time.
Answer:
The correct answer will be - Primary structure
Explanation:
Proteins are one of the biomolecules formed by the process of translation.
Depending on the function they attain many structures like primary, secondary, tertiary and Quaternary structure.
The primary structure is the simplest structure formed by binding the amino acids via peptide bonds in linear order. This simplest structure is formed by the process of translation in which tRNA brings specific amino acids to the nascent peptide.
Thus, Primary structure is the correct answer.
Answer:
A) The radial orientation of cellulose microfibrils in the cell walls of guard cells causes them to bow outward and open when the stomatal pore when turgid.
Explanation:
Stomata are pores on the surface of leaves that work as valves controlling the gas exchange in plants; they are bordered by a pair of curved guarded cells in charge of opening and closing by increasing or decreasing the stomatal pore area.
Guard cells walls structure consist of a combination of stiff cellulose microfibrils oriented along the circumference of the cells and a softer matrix material which makes it possible for stomata pore to open by increasing water pressure (turgor).
Option B states that when guard cells become turgid, they close the stomata. This is a false statement as we explained before.
Option C states that light (known stimulant for opening stomata) causes guard cells to become flaccid which is also false. Guard cells become turgid in order to open the stomatal pore.
Option A is correct.
Answer:
Due to the fact that starchy foods are broken down into glucose(which is the body's main fuel) it provides energy for our brain and muscles
Density is important because it affects whether objects will float or sink. it is an important property to consider when building things like ships or a hot air ballon.
