Step-by-step solution for: Modern Biology Study Guide: Sections 1-1 to 1-3 Review | PDF
It looks like you've uploaded a biology review worksheet titled "The World of Biology" from a Modern Biology study guide. Since I can't view images directly, I'll help you solve the problems based on the text you've provided.
Here's the worksheet content and its solutions with explanations:
---
Define the following terms:
1. development
*Answer:* The process by which an organism grows and changes from a simple form (like a fertilized egg) to a more complex adult form. It includes cell division, differentiation, and morphogenesis.
2. reproduction
*Answer:* The biological process by which new individual organisms are produced from their parents. It ensures the continuation of species.
3. organ
*Answer:* A structure made up of two or more types of tissues that work together to perform a specific function in an organism (e.g., heart, liver).
4. tissue
*Answer:* A group of similar cells that work together to perform a specific function (e.g., muscle tissue, nervous tissue).

Write the correct letter in the blank.
1. Biology is the study of
a. animals
b. plants and animals
c. all living things ✔
d. energy transfer
*Explanation:* Biology is the scientific study of all living organisms, including animals, plants, fungi, bacteria, and more. So, "all living things" is the most comprehensive and accurate answer.
2. A short segment of DNA that contains instructions for the development of a single trait of an organism is known as a
a. DNA loop
b. gene ✔
c. library
d. membrane
*Explanation:* A gene is a segment of DNA that codes for a specific protein or RNA molecule and determines a particular trait (like eye color). This is the definition of a gene.
3. An ova cell in a multicellular organism multiply; they become specialized for different functions in a process called
a. sexual reproduction
b. direct with modification
c. photosynthesis
d. cell differentiation ✔
*Explanation:* After fertilization, the zygote divides and the cells become specialized into different types (e.g., nerve cells, muscle cells). This process is called cell differentiation.
4. Homeostasis refers to the
a. organization of cellular structures
b. stable level of internal conditions in organisms ✔
c. organized structure of crystals
d. destruction of tropical rain forests
*Explanation:* Homeostasis is the ability of an organism to maintain a stable internal environment despite external changes (e.g., body temperature, pH balance).
5. Photosynthesis is part of a plant’s
a. metabolism ✔
b. development
c. homeostasis
d. response to stimuli
*Explanation:* Photosynthesis is a metabolic process where plants convert light energy into chemical energy (glucose). Metabolism includes all chemical reactions in an organism, so photosynthesis is part of it.

Vocabulary Review:
1. Development – Growth and change from simple to complex form.
2. Reproduction – Production of new individuals.
3. Organ – Structure made of tissues performing a function.
4. Tissue – Group of similar cells working together.
Multiple Choice:
1. c
2. b
3. d
4. b
5. a
