Ch. 3.3 Both secual and asexual reproduction involve cell division.
Vocabulary: asexual reproduction, binary fission, regeneration
Review:
1. They are the same in prokaryotes.
2. A bud is a bump on the body of a parent that grows until it forms a new organism genetically identical to the parent. In some organisms buds can form anywhere, but in other organisms, buds form at specific places with specialized cells.
3. Asexual reproduction involves only one parent, has a rapid rate, and produces identical offspring. Sexual reproduction involves two parents and produces offspring that have genetic material from both parents.
4. No, because regeneration only happens in multicellular organisms, and prokaryotes are unicellular.
5. Eukaryotic organisms do not undergo binary fission.
6. The offspring would hve more genetic variation.

CH. 3.2 Celll division is part of the cell cycle.
Mitosis Silviasalas

Vocabulary: cell cycle, interphase, mitosis, cytokinesis
Review:
1. interphase and cell division
2. two complete sets of DNA, twice the size of when it was first formed
3. They are identical.
4. Chromosomes form (prophase), chromosomes line up (metaphase), chromosomes separate (anaphase), nuclei form (telophase).
5. In both plant and animal cells, cytokinesis is the division of the cytoplasm. In plant cells a cell plate forms and becomes a new cell wall and cell membrane. In animal cells, the cell membrane pulls inward and pinches into two new cells.
6. Yes, because cytokinesis is the division of the cytoplasm, and prokaryotes have cytoplasm to divide.
CH. 3.1 Cell diviion occurs in all organisms.
Vocabulary: DNA, chromosome
Review:
1. It leads to growth, development, and repair.
2. It condenses and forms chromosomes.
3. Cells divide to make more cells, which allow multicellular organisms to grow. As cells divide, they can specialize.
4. It wraps in coils around proteins, and then compacts further as it arranges into chromosomes.
5. Skin cells wear out quickly, so they duplicate frequently. Brain cells usually last a long time and do not replace themselves often. Skin heals faster because its cells are better equipped to replace themselves.

13.3 Birds meet their needs on land, in water, and in the air.
Vocabulary: endotherm, incubation
13.3 Review
1. Endotherms need to consume food to produce body heat.
2. Down feathers provide insulation. Contour feathers protect the body.
3. feathers; fused and hollow bones, air sacs, crop and gizzard, keen sight and hearing
4. Both birds and reptiles lay eggs with shells. Bird eggs have hard shells while the shells of reptiles´ eggs are flexible. Most reptiles do not incubate their eggs.
5. Flight requires a great deal of energy. If food was plentiful and there was little threat of predation, the birds may no need to fly.

13.2 Amphibians and reptiles are adapted for life on land.
Vocabulary: amphibian, reptile, ectotherm
13.2 Reveiw
1. limbs, lungs, sensory organs adapted for land
2. born with lungs, eggs have shells
3. Its body temperature should go down. The water will cool its body.
4. Diagrams should include adaptations, methods of reproduction, and how animals obtain oxygen.
5. Sample answer: a more streamlined body in sea turtle, webbing on feet of sea turtle, better underwater eyesight and other senses, and more lung capacity in sea turtle
6. Answers should include how environmental factors affect survival rates.

Vertebrates are animals with endoskeletons.
Vocabulary: vertebrates, endoskeleton
13.1 Review
1. because they have an endoskeleton that includes vertebrae, or a backbone
2. gills, a swim bladder, a lateral line, fins, streamlined body
3. Jawless: no jaw, tube-shaped body;
Cartilaginous: skeleton made of cartilage
Bony: skeleton made of bone, scales
4. Sample Answers: similar coloration, body shapes, and similarities in behavior
5. A fish tht retained the eggs inside its body would produce fewer eggs than one that laid its eggs in water. However, eggs protected inside the parent´s body would be less vulnerable to predators.
6. Sharks are very well adapted to their environment and have been able to meet their needs without changing.

Ch. 18.1 The Respiratory System
Lesson Vocabulary: respiratory system, cellular respiration
18.1 Review
1. in the respiration process, to release energy
2. Nose, throat, trachea, and bronchial tubes carry air in and out of the lungs, where gas exchange occurs. Diaphragm and ribs move to cause lungs to expand.
3. also filters air and aids in speaking, couphing, sneezing
4. Diaphragm relaxes up to its original position, pushing lungs upward. At the same time, ribs move inward, collapsing lungs inward. Air moves out of lungs through bronchial tubes into trachea, then into throat and out nose or mouth.
5. Air you inhale contains more O2 and less CO2 than air you exhale.
6. Energy is expended when you exercise; rapid breathing brings more O2 into the body, which can add more energy.
