Answer the following question given this paragraph: Solubility There is usually a limit to how much solute will dissolve in a given amount of solvent. This limit is called the solubility of the solute. Some solutes have a very small solubility, while other solutes are soluble in all proportions. Table 9.2 "Solubilities of Various Solutes in Water at 25C (Except as Noted)" lists the solubilities of various solutes in water. Solubilities vary with temperature, so Table 9.2 "Solubilities of Various Solutes in Water at 25C (Except as Noted)" includes the temperature at which the solubility was determined. Table 9.2 Solubilities of Various Solutes in Water at 25C (Except as Noted). Q: The limit to how much solute will dissolve in a given amount of solvent is called what? Choices: - density - potency - strength - solubility A:
solubility

Answer the following question given this paragraph: Q: Where does much of the blood that enters the atria flow? Choices: - arteries - muscles - lungs - ventricles A:
(Answer)
ventricles
Ques: Answer the following question given this paragraph: Seeds and Pollen as an Evolutionary Adaptation to Dry Land Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes), seeds contain a diploid embryo that will germinate into a sporophyte. Storage tissue to sustain growth and a protective coat give seeds their superior evolutionary advantage. Several layers of hardened tissue prevent desiccation, and free reproduction from the need for a constant supply of water. Furthermore, seeds remain in a state of dormancyinduced by desiccation and the hormone abscisic aciduntil conditions for growth become favorable. Whether blown by the. Q: Unlike bryophyte and fern spores (which are haploid cells dependent on moisture for rapid development of gametophytes), seeds contain a diploid embryo that will germinate into what? Choices: - sperm - gametophyte - ovary - sporophyte A:
Ans: sporophyte
(Q).
Answer the following question given this paragraph: The showy petals of flowers evolved to help attract pollinators. Wind-blown pollen might land just anywhere and be wasted. A pollinator is an animal that picks up pollen on its body and carries it directly to another flower of the same species. This helps ensure that pollination occurs. Pollinators are usually small animals such as bees, butterflies, and bats. You can see an example in Figure below . Q: What is an animal that picks up pollen on its body and carries it to another flower called? Choices: - fungi - lizard - rodent - pollinator A:
(A).
pollinator
Ques:Answer the following question given this paragraph: Very small numbers can also be expressed using scientific notation. The mass of an electron in decimal notation is 0.000000000000000000000000000911 grams. In scientific notation, the mass is expressed as 9.11 10 -28 g. Notice that the value of the exponent is chosen so that the coefficient is between 1 and 10. Q: What system can be used by scientists to express very small numbers? Choices: - similar notation - scientific diffusion - certain diffusion - scientific notation A:

Ans:scientific notation
Ques:Answer the following question given this paragraph: Gram-negative bacteria have a cell wall made of peptidoglycan, whereas Gram-positive bacteria have a cell wall made of lipoteichoic acid. Figure 22.19 Which of the following statements about the nitrogen cycle is false? a. Nitrogen fixing bacteria exist on the root nodules of legumes and in the soil. Denitrifying bacteria convert nitrates (NO3-) into nitrogen gas (N2). Ammonification is the process by which ammonium ion (NH4+) is released from decomposing organic compounds. Nitrification is the process by which nitrites (NO2-) are converted to ammonium ion (NH4+). Q: Gram-negative bacteria have a cell wall made of peptidoglycan, whereas gram-positive bacteria have a cell wall made of what? Choices: - choanocyte acid - solmization acid - hydrolic acid - lipoteichoic acid A:

Ans:
lipoteichoic acid
