Answer:
Australia
Explanation:
it is 2.968 million square miles, therefore making it the largest country in Oceania.
Answer:
Explanation:
Each of these types of scientists focus on different research studies and therefore needs different tools. Field Scientists' studies mainly revolve around observations which they, therefore, need only a pen and paper, this may sometimes change when they need bigger machinery to make a certain event occur, but this machinery is dependent on the type of research. On the other hand laboratory, scientists work with different specimens within the lab and tend to use tools such as Bunsen burner, beakers, reagent bottles, petri dishes, and microscopes.
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.
Gastric inhibitory peptide (GIP) a digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine.
- A member of the secretin family of hormones, glucose-dependent insulinotropic polypeptide is an inhibitory hormone.
- It is sometimes referred to as gastric inhibitory polypeptide or stomach inhibitory peptide.
- The enteroendocrine K-cells, which are widespread in the small intestine secrete GIP.
- The hormone gastric inhibitory polypeptide, which is released by intestinal mucosal cells, prevents the stomach from producing hydrochloric acid.
- Additionally, it improves the islets of Langerhans' beta cells' ability to secrete insulin, which results in a considerable increase in blood insulin concentrations following oral glucose delivery.
