The answer to this question would be: insulin
Insulin is a hormone that produced by the pancreas. Insulin makes sugar go inside cells. Sugar is the food for cells. Without insulin, the sugar can't enter the cell and the cell food is depleted. This will cause the body feel that the sugar is not enough and trying to increase the sugar concentration. This will result in the increases of blood sugar level.
The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.
Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.
The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.
Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.
Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.
Geothermal is a renewable energy, because it is from the heat produced by the earth. The earth gets heat from the sun, which will be there for the next million of years. Geothermal has benefits, because if we harness the use of it, instead of mining out all of our coal and oil, we can use this for a long run, and only leave non-renewable energy resources for backup. However, there are consequences to communities and surroundings. The geothermal only benefits when the earth is warm. When the earth becomes too warm, we wouldn't even need the energy anymore cuz everythings dead. So we can use this, but overall we must try to lower the amount of resources that produce this thing as possible.. ( use other renewable energy)
hope this helps
Climate change , global warming , and population growth are all threats to biodiversity.
Answer:
C or E
Explanation:
The answer is excretion only. Excretion is the expelling of waste products, water included. Transpiration is a form of water cycle, but it refers to the evaporation of water from aerial parts and its movement through plants. Respiration is the process of breathing which is mostly separate from the water cycle.
