Q: Which law states that a pair of alleles is separated, or segregated, during the formation of gametes? Read this paragraph and choose the correct option from the provided answers: Mendel summarized his findings in two laws: the Law of Segregation and the Law of Independent Assortment. The Law of Segregation is based on his findings from his first set of experiments. Mendel stated that heritable factors are segregated during gamete formation. More precisely, this law states that a pair of alleles is separated, or segregated, during the formation of gametes. During meiosis, homologous chromosomes are randomly separated. Each resulting gamete has an equal probability or chance of receiving either of the two alleles. In other words, each gamete has only one allele for each gene. Choices: - de facto segregation - law of equals - separation anxiety - law of segregation A:
law of segregation

Q: Intermediate filaments tend to give the structural stability to what? Read this paragraph and choose the correct option from the provided answers: 8.7.1 Intermediate Filaments These are rope like filaments, 8-10nm in diameter and tend to give the structural stability to cells. Examples inculude Vimentin, neurofilaments and keratin. It is keratin which priniciply makes up hair, nails and horns. Choices: - nerves - proteins - muscles - cells A:
cells

Q: Q: What two types of juices help digestion within the small intestine? Read this paragraph and choose the correct option from the provided answers: Chemical Digestion in the Small Intestine The digestion of proteins and carbohydrates, which partially occurs in the stomach, is completed in the small intestine with the aid of intestinal and pancreatic juices. Lipids arrive in the intestine largely undigested, so much of the focus here is on lipid digestion, which is facilitated by bile and the enzyme pancreatic lipase. Moreover, intestinal juice combines with pancreatic juice to provide a liquid medium that facilitates absorption. The intestine is also where most water is absorbed, via osmosis. The small intestine's absorptive cells also synthesize digestive enzymes and then place them in the plasma membranes of the microvilli. This distinguishes the small intestine from the stomach; that is, enzymatic digestion occurs not only in the lumen, but also on the luminal surfaces of the mucosal cells. For optimal chemical digestion, chyme must be delivered from the stomach slowly and in small amounts. This is because chyme from the stomach is typically hypertonic, and if large quantities were forced all at once into the small intestine, the resulting osmotic water loss from the blood into the intestinal lumen would result in potentially life-threatening low blood volume. In addition, continued digestion requires an upward adjustment of the low pH of stomach chyme, along with rigorous mixing of the chyme with bile and pancreatic juices. Both processes take time, so the pumping action of the pylorus must be carefully controlled to prevent the duodenum from being overwhelmed with chyme. Choices: - chyme and phloem - amniotic fluid, bile - bile and lymph - intestinal and pancreatic A:
A: intestinal and pancreatic

Question: Q: What process is magnesium important to? Read this paragraph and choose the correct option from the provided answers: Magnesium (Mg) and calcium (Ca) are also important macronutrients. The role of calcium is twofold: to regulate nutrient transport, and to support many enzyme functions. Magnesium is important to the photosynthetic process. These minerals, along with the micronutrients, which are described below, also contribute to the plant's ionic balance. In addition to macronutrients, organisms require various elements in small amounts. These micronutrients, or trace elements, are present in very small quantities. They include boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni), silicon (Si), and sodium (Na). Deficiencies in any of these nutrientsparticularly the macronutrientscan adversely affect plant growth (Figure 31.4. Depending on the specific nutrient, a lack can cause stunted growth, slow growth, or chlorosis (yellowing of the leaves). Extreme deficiencies may result in leaves showing signs of cell death. Choices: - dna replication - carbon cycle - absorption - photosynthetic A:
Answer: photosynthetic

(Q).
Q: What is the process of producing eggs in the ovary is called? Read this paragraph and choose the correct option from the provided answers: The process of producing eggs in the ovary is called oogenesis. Eggs, like sperm, are haploid cells, and their production occurs in several steps that involve different types of cells, as shown in Figure below . You can follow the process of oogenesis in the figure as you read about it below. Choices: - gametogenesis - meiosis - morphogenesis - oogenesis A:
(A).
oogenesis
