This is an example of evolution through natural selection. The peppered moths started off with a light color scheme when the industrial revolution started, and they had this to blend into the trees. The better the moths could blend in, the less likely they were to be preyed upon. Once the trees changed colors, the light moths were vulnerable. The months that thrived in this change were the darkly colored moths. These moths then bred and spread their dark color pattern to best fit into the new environment.
Answer:
Both photosynthesis and cellular respiration occur in plants. However, the rate of photosynthesis exceeds that of cellular respiration during the day when there is sunlight. The Chlorophyll pigment picks up energy from the photons and uses it to reduce carbon dioxide into carbohydrates. During the night, when there is little sunlight, the rate of photosynthesis drops down below that of cellular respiration, that breaks down these energy molecules made in photosynthesis to supply the plant’s cellular processes with energy.
Answer:
Glaciers picking up boulders is not a type of erosion
Explanation:
The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks. Attrition is the collision between sediment particles that break into smaller and more rounded pebbles. Hydraulic action is the force of water against the banks compressing air pockets into cracks, which expand and fracture the rock over time. Solution is the process of acidic water dissolving soluble sediment.
The question is incomplete as it is incomplete therefore a picture of the complete question has been attached.
Answer:
To be used by the cells for energy
Explanation:
The digestive process of humans digest or breakdown or oxidise the organic molecules present in the food to simple compounds which could be easily utilised by the human body.
The human body composed of tissue and cell requires energy to perform metabolic reactions in the form of ATP which are provided by the digestion of the complex food material.
The macronutrients present in the food thus are digested and absorbed by the cells to perform reactions which could provide energy therefore the selected option is the correct answer.
C. Oxygen and nutrients taken in by the respiratory system are transported to the circulatory system for transport around the entire body.
Also, B and D cannot be correct, as carbon dioxide is not wanted in the body (it's a waste product of respiration of the body cells)
