Kingdom Protists is the kingdom that is composed if eukaryotes which are mostly unicellular and that can be heterotrophic and or autotrophic.
Answer:
W - Facilitates movement of air by expansion and contraction, X - Traps dust and helps to filter inhaled air, Y - Prevents the wind pipe from collapsing, Z - Help in exchange of gases.
Explanation:
Diaphragm is the muscle that separates the thoracic cavity from the abdomen. The diaphragm is the main muscle of respiration. Contraction of the diaphragm muscle expands the lungs during inspiration when breathing air in. The function of the nasal cavity is to warm, moisturize, and filter air entering the body before it reaches the lungs. Hairs and mucus lining the nasal cavity help to trap dust, mold, pollen and other environmental contaminants before they can reach the inner portions of the body. The trachea, or windpipe, is a 5-inch long tube made of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium. The trachea connects the larynx to the bronchi and allows air to pass through the neck and into the thorax. The rings of cartilage making up the trachea allow it to remain open to air at all times. Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues.
Drawing a punnet square on a seperate peice of paper (which I did) we have the traits as follows:
YY
Yy
Yy
yy
So as seeing 1 of 4 is defenitly a Red (yy) 2 of the flowers are 50/50 being red or yellow. I'm not really sure which answer is correct but I would choose answer 3 as there are 3 flowers with the chance of being red.
HOPE THIS HELPED!!

Hi! :)
If a scientist collects evidence that questions the basics of a scientific theory, this means the theory is
going to be refined by further investigation !
