In a particular human family, John and his mother both have brachydactyly (a rare autosomal dominant allele causing short finger

Answer:

TRUE

Explanation:

Green plants possess chlorophyll, a green pigment in their leaves. Chlorophyll can absorb the sunlight required for photosynthesis to occur. Photosynthesis refers to the process by which green plants produce food in the presence of light, water (H₂O), and carbon dioxide (CO₂), resulting in the release of glucose and oxygen (O₂) needed for the survival of all living beings.

The reaction that occurs during photosynthesis is illustrated below-

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

This method converts light energy into chemical energy, which is stored in glucose molecules.

Consequently, the statement is TRUE.

Response:

W - Aids in air movement through expansion and contraction, X - Catches dust and assists in filtering inhaled air, Y - Ensures the windpipe remains open, Z - Facilitates gas exchange.

Clarification:

The diaphragm, separating the thoracic cavity from the abdomen, serves as the primary respiratory muscle. When contracted, it expands the lungs during inhalation, allowing air intake. The nasal cavity’s role is to warm, moisten, and filter the incoming air before it reaches the lungs. Hairs and mucus in the nasal cavity trap dust, mold, pollen, and other environmental pollutants before they can infiltrate the body's inner sections. The trachea, a 5-inch tube constructed of C-shaped hyaline cartilage rings lined with pseudostratified ciliated columnar epithelium, connects the larynx to the bronchi and permits air passage through the neck into the thoracic area. The cartilage rings maintain the trachea's openness for airflow consistently. The gas exchange of oxygen and carbon dioxide occurs within the alveoli; oxygen from inhaled air diffuses through the alveoli walls and adjacent capillaries into red blood cells, which then transport the oxygen to body tissues.

Answer:

36

Explanation:

A two-point test cross involves mating an individual with a double heterozygote genotype against a homozygous recessive one to ascertain the recombination frequency between two linked genes. In genetic terms, one map unit (m.u.) is indicative of the genetic distance separating genes for which one (1) of a hundred (100) meiotic products is recombinant. Here, 36 of the progeny exhibited the recombinant phenotype, while the other 64 did not, indicating that the two genes are spaced by 36 mu (64 + 36 = 100 >> 36 mu).
