All living things grow and develop as they progress through their life cycle. Evidence includes measuring physical changes, observing physical appearance, monitoring behavioral changes, and studying gene expression.
All living things grow and develop as they progress through their life cycle. This can be observed through physical changes and increased complexity in structure and function as organisms mature. For example, a seedling grows into a fully grown plant, a tadpole develops into a frog, and a fertilized egg grows into a baby and eventually an adult.
Evidence to show growth and development in living things includes:

Answer:
The main function of the palisade tissues of the leaf is to absorb light to perform photosynthesis! They contain lots of chlorophyll, which is the main organelle used for turning sunlight into glucose (the plant's "food")
They are tucked right underneath the epidermal layer, which is transparent so it allows sunlight to come through.
Answer:
that means they are not a prey to any animal
Answer:
It starts in the mouth Enzymes break down food
Explanation:
Mechanical digestion is a type of digestion which is done by breaking of food materials into small pieces through physical means such as cutting and crushing by teeth and muscular contraction of stomach while the break down of food molecules by the action of enzyme such as saliva etc is chemical digestion. Chemical digestion helps in speeding up the process of digestion.
Answer:
D. Enzymes break down food.
Explanation:
Mechanical digestion is the physical breaking down of food that starts in the mouth by chewing. Enzymes would be part of the chemical digestion.
The animal burrows in Diagram B are an example of mechanicalweathering, and weathering is of many types, such as physical, chemical, and mechanicalweathering.
Weathering is a process in which the chemical composition of the matter may or may not change, the size of the matter may or may not change, etc. There are different types of weathering, such as physical weathering, chemical weathering, and mechanical weathering.
Mechanical weathering is a type of weathering in which changes can be seen, such as roots growing in rocks, whereas chemical weathering changes the chemical composition. The chemical weathering changes the composition so that the original and the new composition change in seen in the case of the rocks, the soil, etc., and in the physical weathering the size changes, such as from the large rock to the smaller form.
Hence, the animal burrows in Diagram B are an example of mechanicalweathering.
