when is glycogen , which is stored in the liver , converted into glucose and released into the blood ?
Answer:
This stored form of glucose is made up of many connected glucose molecules and is called glycogen. When the body needs a quick boost of energy or when the body isn't getting glucose from food, glycogen is broken down to release glucose into the bloodstream to be used as fuel for the cells.

https://brainly.com/question/13979184
Answer:
Ecosystem Services refer to the benefits that humans receive from the natural environment. They are the various processes and functions that ecosystems provide, such as the purification of air and water, nutrient cycling, and the provision of food, fuel, and fiber. Ecosystem Services are crucial for human survival and well-being, and they are essential for maintaining the balance of the planet's natural systems. One example of an ecosystem service is the pollination of crops by bees and other insects. Pollinators are responsible for fertilizing flowers, which allows plants to produce fruits, vegetables, and seeds. Without pollinators, many crops would not be able to produce a yield, resulting in a significant reduction in food production. Additionally, pollinators are essential for maintaining the diversity of plant species, which is essential for the health of ecosystems. The economic value of pollination services has been estimated to be worth billions of dollars annually. Another example of an ecosystem service is the role of wetlands in mitigating flooding and reducing erosion. Wetlands act as natural sponges, absorbing and storing water during heavy rainfall and releasing it slowly over time. This helps to reduce the risk of flooding downstream and prevents soil erosion. Wetlands also provide important habitats for a diverse range of plant and animal species, which supports the overall health and resilience of ecosystems. The economic value of wetlands in terms of flood control and erosion prevention has been estimated to be worth billions of dollars. In conclusion, ecosystem services are essential for human well-being and the health of the planet's natural systems. They provide a wide range of benefits, including food production, water purification, flood control, and erosion prevention. The examples of pollination and wetlands demonstrate how ecosystem services benefit people by supporting food production and reducing the risk of natural disasters. It is important to recognize the value of ecosystem services and to take steps to protect and conserve them for future generations.

compare and contrast the five types of evidence that support the theory of evolution
There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology. The basic idea of natural selection is that a population of organisms can change over the generations if individual having certain heritable traits leave more offspring than other individuals. The result of natural selection is evolutionary adaptation, a population’s increase in the frequency of traits that are suited to the environment. In modern terms, we would say that the genetic makeup of the population has changed over time, and that is one way to define evolution. Evolution leaves observable signs. There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.

list 3 differences between sun leaves and shade leaves
Answer:
Partial sun is between four and six hours of sun a day. Partial shade is two to four hours of sun per day. Shade, in gardening terms, means less than two hours of sunlight a day. Leaves which grow in the shade ('shade leaves') are generally larger in area but thinner than leaves which grow in full sunlight ('sun leaves'). Sun leaves become thicker than shade leaves because they have a thicker cuticle and longer palisade cells, and sometimes several layers of palisade cells.
