As winter approaches some animals such as the ruby throated hummingbird respond with other animals such as chipmunks respond with
Answer: instinct, stimulus
Explanation: Im just that smart
Hummingbird responds to winter with migration, whereas Chipmunks responds to winter with hibernation.
What causes animals to hibernate or migrate?Hibernation is the state that occurs in animals in which they enter a deep sleep in order to endure the freezing winter months and the lack of food. For example, Polar beer loses its activity throughout the cold months. The movement of birds from one location to another, either in search of food or as a response to changes in the weather, is referred to as migration.
When an animal is unable to migrate, it will either hibernate or employ some other method in order to secure food and shelter for itself. The state of hibernation is analogous to that of an extremely deep slumber. The animal's body temperature will begin to drop, and it will also experience a slowdown in both its heart rate and its breathing rate. This assists the animal in conserving its energy so that it can endure the winter.

How do mountains affect the climate of a region?
(giving brainlist)
Answer:
As context, there are two sides of a mountain range:
A) The windward side
B) The leeward side
As mountains are tall, they block clouds which are in the troposphere. All the moisture thus falls onto the windward side, while almost none of the moisture from the rain gets to the leeward side.
In a nutshell, mountain ranges create barriers for precipitation which blocks off moisture to the leeward side, creating deserts.
This is why you see mountain ranges near deserts.

Answer:
A frameshift mutation is a genetic mutation caused by a deletion or insertion in a DNA sequence that shifts the way the sequence is read. ... For instance, if just one nucleotide is deleted from the sequence, then all of the codons including and after the mutation will have a disrupted reading frame.
Answer:
