making hypotheses
for each question below, write a hypothesis (or guess to the answer of the question) as an “if i.... then...” statement.

1. how does water affect the growth of a plant?

if i __ then __

1. how does the amount of sunlight affect the growth of a plant?

if i __ then __

characteristics of life

1. how many characteristics of living things do you need to be considered alive? ____
2. what are the eight characteristics of living things?

• cells
• adapt to environment
• respond to changes in environment
• dna
• reproduce
• use energy
• grow and develop
• stable internal environment

Explanation:

1. A hypothesis is an educated - guess in science. For the plant - water question, we consider the relationship between water quantity and plant growth. For the sunlight - plant question, we think about how sunlight amount impacts growth. For the oxygen - cell energy question, we consider the connection between oxygen availability and cell energy production. Regarding the characteristics of life, all eight characteristics are generally considered necessary to be truly alive.
2. The eight characteristics of life are fundamental in defining living things. Cells are the basic unit, adaptation helps in survival, responding to environmental changes is crucial for well - being, DNA contains genetic information, reproduction ensures the species' continuation, using energy is needed for all life processes, growth and development mark the life cycle, and maintaining a stable internal environment is vital for homeostasis.

Answer:

1. Hypothesis
2. If I give a plant more water, then the plant will grow taller.
3. If I provide a plant with more sunlight, then the plant will grow faster.
4. If I increase the amount of oxygen available to my cells, then my cells will make more energy.
5. All eight characteristics are typically needed to be considered alive.
6. Cells, Adapt to environment, Respond to changes in environment, DNA, Reproduce, Use energy, Grow and develop, Stable internal environment
