I really need help on thisDiscussion TopicEach substance has a unique set of properties that depends on the kinds of atoms it has and how the atoms are connected, or bonded. Bonding is related to the electrons in an atom, and there are different kinds of bonds. As a result, some substances can have the same atoms but different bonds. Substances that are different but have the same atoms are called allotropes. Allotropes have very different properties.Diamond and graphite are well-known allotropes. Graphite is used in pencils for writing and is sometimes called lead. Diamond is colorless and transparent, and is one of the hardest substances known. Graphite is dark gray and soft. When we write, layers of graphite easily transfer from the pencil to the paper. Although they’re different, diamond and graphite each only contain one kind of atom—carbon.How do you think the bonds between carbon atoms might be different in diamond and graphite? Use household materials to build physical models to help you develop your ideas. Describe what you learned from your models. What other kinds of allotropes are there? What kinds of properties and atomic bonds do they have? |

Answer» Answer: Diamond and GRAPHITE are well-known that all TAPS as used is peanut as of transpert DIFFERENT DIAMONDS etc.. |

The process of respiration is?a) oxidation & enothermic d) decomposition & enothermic c) combination & exothermic d) oxidation and exothermic |
|
Answer» Explanation: Respiration: The PROCESS of releasing energy by the oxidation of food is known as respiration. The process of respiration involves intake of oxygenated air into the cells for breaking the food and releasing energy. Mechanism of respiration: i. Air is drawn into the body through the nostrils. ii. The air from the nasal cavity passes to the pharynx, which leads to the trachea, through a slit called glottis. iii. The trachea runs down the neck and divides into two bronchi, which lead into the lungs and further divide into smaller bronchioles. The smallest bronchioles TERMINATE into alveoli. iv. The walls of the alveoli are thin and covered by blood capillaries to FACILITATE the exchange of gases in the lungs. v. In the alveoli, the exchange of gases takes place, CO 2
from the blood is replaced with O 2
and CO 2
is removed out of the body. vi. In humans, for the process of respiration, air is drawn into the lungs by the process of breathing. When an individual inhales, the diaphragm moves down, and the chest cavity expands and the oxygen rich air is drawn into the lungs. When the individual exhales, the diaphragm relaxes and the chest cavity moves BACK to its relaxed position and the carbon DIOXIDE rich air is expelled out of the body. |

Diffedifferentiate between weather and climate why do tropical rainforests have large population of animals |
|
Answer» Answer: The main difference between these two terms is the DURATION, where the WEATHER is the day-to-day or SHORT term condition of the changes in the atmosphere, and climate is the averaged weather condition of a particular place over a long time, about 30 years. Like for instance, we talk about the weather in terms of “hot it will be today?” “Will it RAIN or not”? Or “What about the snowstorm this WEEK”?. On the other hand, climate changes are observed in term of years, decades and centuries and include statistical weather information, that provides us with the regular weather report. |

E. Answer the following questions.1. Name the organ that helps the fish to swim?2. How do the insects fly?3. Give two examples of reptiles.4. How do the mammals move?5. How does the antennae help the insect?6. How do the amphibians lay their eggs nBrain Sharpening Questions |
|
Answer» Answer1:Most fish have an organ called the SWIM bladder. It is a flexible, gas-filled sac located in the dorsal or top portion of the body cavity and helps to control the fish's buoyancy. Answer2:Many insects can hover, or stay in one spot in the air, doing so by beating their wings rapidly. ... As the wings push down on the surrounding air, the result reaction force of the air on the wings force the insect up. The wings of most insects are evolved so that, during the upward stroke, the force on the wing is small. Answer3:The major groups of living reptiles—the turtles (order Testudines), tuatara (order Rhynchocephalia [Sphenodontida]), lizards and SNAKES (order Squamata), and crocodiles (order Crocodylia, or Crocodilia)—account for over 8,700 species. Answer4:They live on land, in the open ocean, and underground. With more than 5,400 species, MAMMALS move in all kinds of ways. They walk, hop, gallop, and swing from trees. They swim, dive, glide, and even fly! Answer5:Antennae (singular: antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. ... Antennae can also locate other group members if the insect LIVES in a group, like the ant. Answer6:Most amphibians live part of their lives underwater and part on land. Amphibians reproduce by laying eggs that do not have a soft skin, not a hard shell. Most females lay eggs in the water and the BABIES, called larvae or tadpoles, live in the water, using gills to breathe and finding food as fish do.

Answer the following questions in brief.1. Why are viruses considered as being at the 'borderline' between livingnon-living things?What is fermentation? How is this process useful in the food and bever |
|
Answer» Explanation: Viruses are considered at the borderline of living and non-living because they SHOW both the characteristics of a living and a non-living. As they react like non-living in the free atmosphere but when they enter the body of a living ORGANISM then they show the features of a living organism and start reproduction. Fermentation in food processing is the process of converting CARBOHYDRATES to alcohol or organic ACIDS using microorganisms—yeasts or bacteria—under ANAEROBIC conditions. Fermentation usually implies that the action of microorganisms is desired. ... Other widely consumed fermented foods include vinegar, olives, and cheese. |
