1. Answers are:
1. World is located, on boilerplate, almost 150 million kilometers from the Sunday. If a planet is too close to the Sun, it may be too hot to back up life. If a planet is too far from the Lord's day, it may exist likewise common cold. The Sun's proximity to World makes Globe a practiced candidate for supporting life.
2. H2o is essential to life as we know it and Earth has lots of h2o.
3. Globe'due south atmosphere is 21% oxygen, a gas nigh organisms demand to survive.
2. (1) H2o is a expert solvent. (2)Water exists as a liquid at a broad range of temperatures; (3)Water helps stabilize temperatures since information technology has a high specific rut value.
3. A solution is water with dissolved substances (called solutes). Many process important for sustaining life occur in solutions.
4. The pond water, the claret of the human and dog, the sap inside of the copse.
5. Gravity is the force that holds Globe's atmosphere in identify.
6. Earth'southward atmosphere has a lot more oxygen and a lot less carbon dioxide than the atmospheres of Mars and Venus.
7. World has living organisms that apply carbon dioxide for photosynthesis, and to build their shells out of calcium carbonate. This removes carbon dioxide from the air.

1. Organisms in the domain Eukarya take true nuclei in their cells.
2. Animalia, Plantae, Fungi, Protista
3. A = order teuthida; B = class gastropoda; C = grade bivalvia; D = social club octopoda; Due east = phylum annelida
4. Internal or external shell present; no internal or external vanquish nowadays
5. The organism belongs to either the domain Archaea or domain Bacteria because it doesn't take a nucleus. It would accept further testing to place the verbal domain to which it belongs.

Connexion

1. Earth's atmosphere keeps global temperatures within a narrow range, shields us from harmful radiations, provides oxygen, and provides the pressure our bodies need to function properly.
2. This garment has a force per unit area bladder and restraint layer, covered by a nylon liner. Together, these layers keep the astronaut's torso from swelling.
3. Astronauts may encounter micrometeroids. The EMU contains a layer to protect them from this hazard. In add-on, carbon dioxide could build up inside of the surroundings. The EMU contains a ventilation system to get rid of excess carbon dioxide.

Concepts

Reading ii.one

1. Examine if information technology responds to stimulus in its environment. Search out others of its kind for evidence of reproducing. Determine if it uses free energy and performs respiration, and acquit further tests to see if it is made of cells.
2. b. growth and evolution
3. A person who increases his heart rate from biking is a response to a stimulus. The stimulus is the free energy exerted from pedaling the bicycle, and the response is increased heart rate and breathing.
4. Because zeedonks cannot reproduce more of their ain kind, they would eventually die off if their population was isolated on an island. Reproduction is an important characteristic of life considering it keeps a species alive.
5. a is an instance of chemical free energy.
6. Humans are made of cells. Different types of cells form tissues. Different tissues grade organs. The center, lungs, and brain are examples of important organs. An organ system is formed when a group of organs work together. The circulatory organization relies on the center, blood vessels, and claret to ship gases and nutrients around the body to different tissues and cells. Each organ arrangement has a set up of functions. Organs inside each organisation take their own function. Together, all organs and organ systems piece of work together to keep the organism alive.
7. c. an organ
8. a. the organism maintaining homeostasis.

Reading ii.2

9. Earth is merely the correct distance from the Sun to support life.
10. Earth's atmosphere provides oxygen and the correct pressure to sustain life. The two most abundant gases are nitrogen and oxygen.
11. World has plenty mass to create a potent enough gravitational field to hold the temper in identify.
12. Photosynthesis is the process that uses carbon dioxide in the temper to create oxygen and food. This keeps the carbon dioxide levels low and adds oxygen to the atmosphere.
13. Three means the Earth stores carbon are: (1)Plants shop it in the form of carbon molecules; (2)marine organisms apply carbon to make their shells out of calcium carbonate. When they dice, their shells sink to the lesser of the ocean, storing the carbon; (iii)Fossil fuels shop carbon from decaying found textile.

Reading 2.3

14. d
15. c
16. a
17. nucleus or no nucleus? consumer or producer? single-celled or multicellular?
18. Scientific names are of import because at that place are many unlike common names for organisms. Scientific names are assigned to each species and also help classify them into the correct levels. Also, considering in that location are many dissimilar languages, scientific names ensure that there is a standard name for all known organisms.
19. Eukaryotes have a true nucleus while prokaryotes exercise not have a true nucleus. Prokaryotes can be divided into two domains: Archaea and Bacteria. All eukaryotes belong to the domain Eukarya.
20. A dichotomous key contains pairs of contrasting statements that assist people place an organism or group of organisms.
21. A = form mammalia; B = class aves; C = phylum echinodermata; D = class amphibia; E = phylum arthropoda

Math and Writing Skills

1. A cloud may qualify as a living thing considering it moves equally a response from the winds and it grows as moisture collects inside the cloud. Ways clouds are not like living things include non existence fabricated of cells, not reproducing themselves, and non requiring energy to survive.
2. As students write a story nigh homeostasis, they should emphasize the ability to maintain stability or equilibrium in the system. It might be helpful to have students listing activities they do during a typical 24-hour interval earlier they begin the assignment. They tin use their list to decide activities they do that influence homeostasis. Fifty-fifty every bit they sleep, their body systems perform functions that encourage internal remainder, such as maintaining a constant body temperature.

3. Sample respond: The air is 78% nitrogen. Organisms in the soil "fix" nitrogen so it can then be taken up by plants. Plants use the nitrogen to build their tissues. When animals consume plants, they utilise the nitrogen in plant tissues to build proteins that make upwards their bodies. When humans eat animals and plants, they also use the nitrogen to build the proteins that brand upward their bodies.
4. The cytoplasm of cells is a good instance of a solution in a living system. Cytoplasm contains a solution of h2o with dissolved substances.

5. Student answers will vary. Students should describe how they employ the classification arrangement in the store to find their items. For example, the CD would be found in the music department, whereas the shampoo would be found in the personal hygiene section. Socks would be found near the shoe department.
6. See graph below:

7. For this question, students will pretend that they are scientists who found the creature shown. They should analyze characteristics of the creature to determine what kingdom it would fit into. Every bit students observe characteristics of the beast, they demand to determine a scientific name and write about how the creature lives. They should include specific facts about the organism, such as its food, habitat, and other organisms with which it interacts. Students should exist artistic and apply their cognition of the characteristics of living things to their story.
8. For question b, answers may vary. Ane scenario:
1. Object has 3 sides ...................................... go to question 2.
