input: OPTIONS:
- proteins
- vitamins
- carbohydrates
- enzymes Now, answer this question: Answer the following question given this paragraph: Enzymes are critical to the body's healthy functioning. They assist, for example, with the breakdown of food and its conversion to energy. In fact, most of the chemical reactions in the body are facilitated by enzymes. Q: Most of the chemical reactions in the body are facilitated by what? A:
A:
output: enzymes

Answer: heat

Problem: OPTIONS:
- diverse factors
- nucleic factors
- Dead factors
- abiotic factors
Q: Answer the following question given this paragraph: Abiotic factors are the nonliving parts of ecosystems. They include air, sunlight, soil, water, and minerals. These are all things that are needed for life. They determine which living things and how many of them an ecosystem can support. Figure below shows an ecosystem and its abiotic factors. Q: What is the name for the nonliving parts of ecosystems? A:
Answer: abiotic factors

Problem:OPTIONS:
- thermometer
- scale
- ruler
- barometer

Answer the following question given this paragraph: Atmospheric pressure can be measured with a barometer. Q: Atmospheric pressure can be measured with what tool? A:
****
A: barometer

Answer the following question given this paragraph: Comparing Meiosis and Mitosis Mitosis and meiosis are both forms of division of the nucleus in eukaryotic cells. They share some similarities, but also exhibit distinct differences that lead to very different outcomes (Figure 11.7). Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new cells. The nuclei resulting from a mitotic division are genetically identical to the original nucleus. They have the same number of sets of chromosomes, one set in the case of haploid cells and two sets in the case of diploid cells. In most plants and all animal species, it is typically diploid cells that undergo mitosis to form new diploid cells. In contrast, meiosis consists of two nuclear divisions resulting in four nuclei that are usually partitioned into four new cells. The nuclei resulting from meiosis are not genetically identical and they contain one chromosome set only. This is half the number of chromosome sets in the original cell, which is diploid. Q: Mitosis and meiosis are both forms of division of the nucleus in these? A:
OPTIONS:
- converts cells
- endogenous cells
- reproduction cells
- eukaryotic cells
eukaryotic cells

Answer the following question given this paragraph: Introduction Coral reefs are home to about 25% of all marine species. They are being threatened by climate change, oceanic acidification, and water pollution, all of which change the composition of the solution we know as seawater. Dissolved oxygen in seawater is critical for sea creatures, but as the oceans warm, oxygen becomes less soluble. As the concentration of carbon dioxide in the atmosphere increases, the concentration of carbon dioxide in the oceans increases, contributing to oceanic acidification. Coral reefs are particularly sensitive to the acidification of the ocean, since the exoskeletons of the coral polyps are soluble in acidic solutions. Humans contribute to the changing of seawater composition by allowing agricultural runoff and other forms of pollution to affect our oceans. Solutions are crucial to the processes that sustain life and to many other processes involving chemical reactions. In this chapter, we will consider the nature of solutions, and examine factors that determine whether a solution will form and what properties it may have. In addition, we will discuss colloidssystems that resemble solutions but consist of dispersions of particles somewhat larger than ordinary molecules or ions. Q: Dissolved oxygen in seawater is critical for sea creatures, but as the oceans warm, oxygen becomes less what? A:
OPTIONS:
- insoluble
- abundant
- saturated
- soluble

Answer:
soluble
