b. having an exoskeleton
c. building a cocoon
d. providing for themselves
Answer:
a
Explanation:
a. Supply oxygen to cells for cellular respiration
b. Circulate blood through the blood vessels
c. Rid the blood of water and metabolic wastes
d. Decrease moisture stored in the blood and lungs
The respiratory system's primary job is to provide cells with oxygen so they may respire. This procedure entails absorbing oxygen from the atmosphere, delivering it to the body's cells, and exhaling carbon dioxide as waste.
The cells utilise the oxygen to produce ATP (adenosine triphosphate), which is a kind of energy. The cells then use this energy to perform a variety of tasks. The body's blood circulation is aided by the respiratory system.
It achieves this by assisting in the pumping of oxygen-rich blood to the rest of the body through the diaphragm. By doing this, it is possible to guarantee that the body's cells get enough oxygen. Finally, the respiratory system helps rid the metabolic wastes and a body of water.
Carbon dioxide, a waste product of cellular respiration, is exhaled to accomplish this. This enables the body to operate effectively by preserving thae right balance of water and metabolic wastes. In conclusion, the respiratory system's primary job is to provide cells with oxygen so they may respire.
Additionally, it aids in blood circulation throughout the body and removes water and metabolic wastes.

Explanation:
took the test
b. more air to push through the rima glottidis
c. more taut vestibular folds
d. longer and thicker vocal folds e) wider arytenoid cartilages
Answer:
The most likely genotypes for the two blue budgies would be yyBb
Explanation:
There are three options to cross two blue parakeets:
yyBB x yyBB
yyBB x yyBb
yyBb x yyBb
of the first option, the F1 genotypes will be 100% yyBB (blue)
In the second option, the F1 budgies will be yyBB or yyBb (blue in both cases). In contrast, in the third option, the F1 genotypes will be yyBB, yyBb (blue in both cases) and yybb (white).
The process of converting the genetic message from DNA into RNA is called transcription.
Transcription is the phase of gene expression in which a certain part of DNA is copied into RNA. Transcription is carried out by the enzyme RNA polymerase which joins nucleotides to produce an RNA strand and uses a DNA strand as a template. The three stages involved in transcription are initiation, elongation, and termination.
For reactants to form bonds, there must be an initial energy input to drive the collision of atoms, ions, and molecules. This collision enables the breaking and formation of bonds. Both synthesis and exchange reactions demonstrate this process.
In order for reactants to form bonds during a chemical reaction, a few conditions must be met. Firstly, an initial investment of energy is required. This energy, often in the form of heat, provides the kinetic energy necessary to fuel the collisions of atoms, ions, and molecules. This collision must occur in an orientation that allows contact between the atoms that will become bonded together in the product. Secondly, the particles of reactant must come into contact with each other before they can react. This could be a direct collision or through another medium that facilitates the interaction.
Once the reactants collide, bonds are broken in the initial molecules, and new bonds are formed to create the product. Energy is required for breaking old bonds and is released when new ones are formed. This process can be seen in both synthesis reactions (two components bond to form a larger molecule) and exchange reactions (bonds are both formed and broken as components of the reactants are rearranged).
