The absolute threshold for human vision is the ability to see a candle from 30 miles away on a dark night
Explanation:
An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem.
These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions.
Oxygen is an inorganic gas that makes up the atmosphere, thus it is abiotic
; it is utilized by animals which undergo cellular respiration to produce energy for life processes. A field mouse may continue to reproduce, increasing the population, and feed on other biotic factors, and aid in nutrient cycling.

As prey increase predatory increase and as prey decrease due to the increase of predators. The number of predators will decrease due to the lack of foods.
Answer:
38. Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
39. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas
40. Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
41. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer:
true
Explanation:
Similarly, expression of a human gene in yeast and bacteria allows pharmaceutical companies to produce insulin to treat diabetic patients. In 2020, scientists had their first successful human trial with CRISPR (a genetic engineering technique), to correct a mutant gene that causes sickle cell anemia, a painful and sometimes deadly blood disease.
