Answer:
maintain homeostasis
Explanation:
Lizards are poikilothermic organisms, it means that their body temperature varies over the course of the day. There are poikilothermic organisms including lizards that bask in the sun during the morning and evening hours, and thus they can increase the body temperature
The islets of Langerhans are microorgans located in the pancreas.
<h3>The islets of Langerhans </h3>
The islets are formed by polygonal or rounded cells, arranged in cords, around which there is an abundant network of blood capillaries with fenestrated endothelial cells.
<h3>Types of islets of Langerhans</h3>
- Alpha (A) cells: secrete glucagon. In humans, these cells have regular-shaped granules containing a dense center surrounded by a clear region under the membrane.
- Beta (B) cells: secrete insulin and amylin. B cells have irregular granules with a center formed of irregular crystals of insulin complexed with zinc.
- Delta cells (D): synthesize somatostatin.
- PP (F) cells: contain a pancreatic polypeptide.
With this information, we can conclude that the islets of Langerhans are microorgans that constitute a large production of products for the maintenance of life.

Answer:
Most of the metabolic activities occur in the cytoplasm of the cell.
Cytoplasm is a gel-like fluid present within the cell. It consists of all the contents enclosed within a cell membrane excluding the nucleus.
It is mainly composed of water but also contains salts, enzymes, organelles, and organic molecules.
It is the main site for most of the cellular processes such as glycolysis (first stage of cellular respiration), protein synthesis, mitosis and meiosis etc.
You need energy to create a chemical bond. The quick moving atoms will create the energy needed for then to occur a chemical reaction.
The answer is : The rock cycle is driven by energy from the Sun as well as from the interior of Earth. The sun provides energy for surface processes such as weathering, erosion, and transport. This is the one of the major source of energy for the rock cycle. Weathering happens when there is a interaction with the air, water and organism which cause the rock to break down, and the pieces of rock are carried away by wind, moving water, etc. through erosion.
