Q: Answer the following question given this paragraph: In plants and algae, photosynthesis takes place in chloroplasts. (Photosynthetic bacteria have other structures for this purpose. ) A chloroplast is a type of plastid, or plant organelle. It contains the green pigment known as chlorophyll . The presence of chloroplasts in plant cells is one of the major ways they differ from animal cells. You can see chloroplasts in plant cells Figure below . Q: In plants and algae where does photosynthesis takes place in? A:

OPTIONS:
- cell wall
- nucleus
- cytoplasm
- chloroplasts

A: chloroplasts

input: OPTIONS:
- lock
- handle
- pivot
- lever Now, answer this question: Answer the following question given this paragraph: The canoe paddles, nutcracker, and hammer that you read about in this lesson have something in common. All three are examples of a type of simple machine called a lever. Q: Canoe paddles, nutcracker, and hammer are examples of what type of simple machine? A:
A:
output: lever

Answer the following question given this paragraph: Water as a Component of Liquid Mixtures A mixture is a combination of two or more substances, each of which maintains its own chemical identity. In other words, the constituent substances are not chemically bonded into a new, larger chemical compound. The concept is easy to imagine if you think of powdery substances such as flour and sugar; when you stir them together in a bowl, they obviously do not bond to form a new compound. The room air you breathe is a gaseous mixture, containing three discrete elementsnitrogen, oxygen, and argonand one compound, carbon dioxide. There are three types of liquid mixtures, all of which contain water as a key component. These are solutions, colloids, and suspensions. Q: What describes a combination of two or more substances, each of which maintains its own chemical identity? A:

OPTIONS:
- bond
- structure
- solute
- mixture

Answer: mixture

Problem: OPTIONS:
- fungi
- sponge
- spores
- algae
Q: Answer the following question given this paragraph: Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. Q: What are plant-like protists called? A:
Answer: algae

Problem:OPTIONS:
- autolysis
- endocytosis
- expulsion
- exocytosis

Answer the following question given this paragraph: Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell, as shown in Figure below . Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin. Newly made membrane proteins and membrane lipids are moved to the plasma membrane by exocytosis. Q: What describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell? A:
****
A: exocytosis

Problem:OPTIONS:
- lizard
- cold-blooded (ectotherm)
- amphibian
- warm-blooded (endotherm)

Answer the following question given this paragraph: Animal Bioenergetics All animals must obtain their energy from food they ingest or absorb. These nutrients are converted to adenosine triphosphate (ATP) for short-term storage and use by all cells. Some animals store energy for slightly longer times as glycogen, and others store energy for much longer times in the form of triglycerides housed in specialized adipose tissues. No energy system is one hundred percent efficient, and an animal's metabolism produces waste energy in the form of heat. If an animal can conserve that heat and maintain a relatively constant body temperature, it is classified as a warm-blooded animal and called an endotherm. The insulation used to conserve the body heat comes in the forms of fur, fat, or feathers. The absence of insulation in ectothermic animals increases their dependence on the environment for body heat. The amount of energy expended by an animal over a specific time is called its metabolic rate. The rate is measured variously in joules, calories, or kilocalories (1000 calories). Carbohydrates and proteins contain about 4.5 to 5 kcal/g, and fat contains about 9 kcal/g. Metabolic rate is estimated as the basal metabolic rate (BMR) in endothermic animals at rest and as the standard metabolic rate (SMR) in ectotherms. Human males have a BMR of 1600 to 1800 kcal/day, and human females have a BMR of 1300 to 1500 kcal/day. Even with insulation, endothermal animals require extensive amounts of energy to maintain a constant body temperature. An ectotherm such as an alligator has an SMR of 60 kcal/day. Energy Requirements Related to Body Size Smaller endothermic animals have a greater surface area for their mass than larger ones (Figure 33.4). Therefore, smaller animals lose heat at a faster rate than larger animals and require more energy to maintain a constant internal temperature. This results in a smaller endothermic animal having a higher BMR, per body weight, than a larger endothermic animal. Q: Metabolism produces waste energy in the form of heat, which helps what type of animal conserve and maintain heat at a relatively constant body temperature? A:
****
A:
warm-blooded (endotherm)
