Answer:
In summer season, sun would not set at latitude 66.5 N and above. In summer season for southern hemisphere, sun would not set for latitude 66.5 S and above.
Explanation:
Season on Earth occurs due to the inclination of the axis about which it rotates. Due to this, there is different length of day and night in different hemispheres at a time.
Sun is highest in the sky in northern hemisphere in summers. So the places at 66.5 N and higher latitude experience 24 hours sun light.
Similarly, in northern hemisphere summers, places at 66.5 S and higher latitude experience 24 hours sun light.
The sun not set in the summer and greater than 66 N

Digestive system includes the esophagus, pancreas, and large intestine. Correct option is A.
The organs mentioned, namely the esophagus, pancreas, and large intestine, are all part of the digestive system. The digestive system is responsible for processing food, breaking it down into nutrients, absorbing those nutrients, and eliminating waste products from the body. Here's a brief description of the mentioned organs' roles in the digestive system:
Esophagus: The esophagus is a muscular tube that connects the mouth to the stomach. Its primary function is to transport food from the mouth to the stomach through a process called peristalsis, which involves rhythmic muscle contractions.
Pancreas: The pancreas is both an endocrine and exocrine gland. As part of the digestive system, it plays a crucial role in producing digestive enzymes and releasing them into the small intestine. These enzymes aid in the breakdown of carbohydrates, proteins, and fats, enabling their absorption.
Large Intestine: The large intestine, also known as the colon, is the final part of the digestive system. It is responsible for absorbing water and electrolytes from undigested food, forming feces, and eliminating waste from the body through the rectum and anus.
Together, these organs work harmoniously within the digestive system to ensure the proper digestion and absorption of nutrients, as well as the elimination of waste materials.

The formation of rust or the iron oxide, is by the chemical reaction between iron and atmospheric oxygen. Hence, it is a chemical change involving the formation of new product.
A chemical change is accompanied by the making or breaking or chemical bonds and the formation of new products. Whereas, a physical change does not involve the change in chemical bond. Phase transitions, change in size,shape etc. are physical changes.
The rust formed in the iron material is iron oxide or Fe₂O₃. This process of forming rust by the action of air or water is called corrosion. Iron reacts with atmospheric oxygen or oxygen from water forms the rust.
The formation of rust makes the material destroy and to prevent this process some anticorrosive materials have to be applied. Hence, formation of rust is a chemical change.
