The pharynx would need to come first in order for C to be correct.
B is also incorrect. Air flows through the bronchioles, then the
alveoli, and finally into or out of the capillaries where gas exchange
can occur with cells.
A is the only option that correctly describes the path of air through the respiratory system in the correct sequence.
The complete flow of air would be:
Nose>pharynx>trachea>bronchi>bronchioles>alveoli>gas
exchange with cells and then back out.
Answer:
The correct answer is explained below:
Explanation:
- According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
- It produces the following gametes: TA, Ta, tA, ta.
- The heterozygous tall, terminal plant has the following genotype: Ttaa
- It produces the following gametes: Ta, ta.
- Crossing them,
TA Ta tA ta
Ta TTAa TTaa TtAa Ttaa
(Tall, Axillary) (Tall, Terminal) (Tall, Axillary) (Tall, Terminal)
ta TtAa Ttaa ttAa ttaa
(Tall, Axillary) (Tall, Terminal) (Short, Axillary) (Short, Terminal)
- The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
- The phenotypes obtained are:
- Tall, Axillary = 3.
- Tall, Terminal = 3.
- Short, Axillary = 1.
- Short, Terminal = 1.
The phosphorous cycle is referred to as a local cycle because it involves an element with no mechanism for long distance transfer.
Phosphorous cannot be found in the air in the gaseous state because it is usually a liquid at standard temperature and pressure and is thus limited in being recycled through water, soil and sediments. However very small particles in the air may contain phosphorous or its compounds.
The phosphorous cycle is the slowest one of the sedimentary cycles.
Answer: adenosine triphosphate (ATP) - the high energy chemical compound with three phosphate groups that provides energy for all other cell activities
endocytosis - when cells engulf or ingest substances
cellular respiration - chemical reactions in plants and animals that break down food molecules into energy (ATP)
movement of particles or molecules from higher concentration to lower concentration - diffusion
when cells expel or get rid of substances from within- exocytosis
a solution that has a higher salt concentration than the salt - hypertonic
the relatively constant state in the internal environment of an organism - homeostasis
Explanation:
Adenosine triphosphate or ATP is the energy currency that is required for providing energy for metabolic functions and activities in the body.
Endocytosis can be defined as the process through which a cell engulfs another cell or substances to get rid of them.
Cellular respiration can be defined as the process through which the food in the organisms is oxidized and broken into parts to release energy.
Diffusion involves the movement or transfer of gas, liquid, and solid particles from a region of higher to lower concentration without the requirement of semi-permeable membrane.
Exocytosis is a process in which the cell releases those substances that are required by the cell.
Hypertonic is a solution that has more solute concentration than solvent concentration.
Homeostasis is a tendency to maintain constancy in the internal environment of body in relation to changes occurring in the surrounding.
