In pea plants, green pod color (G) is dominant to yellow pod color (g). A cross was done between a plant with green pods and a plant with yellow pods. Of the resulting offspring, 50% had green pods and 50% had yellow pods. Which of the following were the genotypes of both parent plants?

The correct answer is D. Water's high specific heat capacity allows it to absorb and store large amounts of heat energy without a significant increase in temperature. Coastal areas, being near large bodies of water, experience less dramatic temperature changes because the water helps moderate temperature fluctuations by absorbing and releasing heat slowly.

The correct answer is B. Atoms become cations by losing electrons. Potassium has one electron in its outermost shell, and it is more likely to lose that electron to achieve a stable, cationic state. Fluorine, helium, and oxygen are more likely to gain electrons and form anions.

The correct answer is C. Psoriasis is a chronic autoimmune skin condition characterized by the rapid buildup of skin cells, and it is considered a noninfectious disease. Chikungunya, dengue, and brucellosis are infectious diseases caused by specific pathogens.

The correct answer is B. When a volcano erupts, it releases built-up pressure and gases, similar to the fizzing of a can of soda when opened. Both involve the release of pressure and trapped substances, leading to an outward expulsion of materials.

The correct answer is A. The endocardium is the innermost layer of tissue that lines the interior surfaces of the heart, providing a smooth surface for blood flow. The myocardium is the middle muscular layer, the pericardium is the outer protective sac, and the epicardium is the outermost layer covering the heart.

The correct answer is B. Uracil is a nitrogenous base found in RNA, replacing thymine which is found in DNA. Adenine, guanine, and cytosine are common to both RNA and DNA.

The pharynx is primarily composed of muscle tissue. It plays a role in swallowing and is part of both the respiratory and digestive systems, which requires coordinated muscular activity.

The correct answer is B. Parathyroid hormone (PTH) regulates blood calcium levels by stimulating the release of calcium from bones, reabsorption of calcium in the kidneys, and absorption of calcium in the intestines. Norepinephrine, growth hormone, and melatonin do not play a primary role in calcium regulation.

The correct answer is A. Chromatin is a complex of DNA and proteins, including histones, found in the nucleus of eukaryotic cells. It carries the hereditary information in the form of genes. ATP, plasmids, and histones are involved in cellular processes but do not carry hereditary information.

The correct answer is C. The digestive system is responsible for breaking down complex food molecules, including proteins, into simpler components such as amino acids that can be absorbed and utilized by the body.
