Beginning in the mid 1600's Earth entered into a mini-ice age. 1815 was known as the "year without a summer" and snow fell in many European countries during the summer months. The prolonged climate change is attributed to low sun spot activity, while the summer snow is believed to be the result of
A major volcanic eruption.
The changes that one can expect to observe as a plant tissue culture develops is the development of new shoots and root.
<h3>What is a Culture?</h3>
This refers to the process in which microorganisms, living matter etc are grown in a specially prepared nutrient medium which are made up of different types of compounds.
In the case of a plant tissue culture, there will be new shoot and root formation due to the presence of nutrients in which the plants are exposed to for its growth and survival.
This is therefore makes changes in the shoot and root be the most appropriate choice.

The purpose of the brain's gyri and sulci, or ridges and grooves, is to increase surface area.
<h3>What is the name for the raised ridges in the cerebrum?</h3>
The shallow grooves on the cerebral cortex's surface are referred to as sulci, while the higher tissue ridges are called gyri.
Signals are transferred between nerve cells in different regions of the brain and body through white nerve fibres that are below the skin. The neocortex, a six-layered structure present in animals, has a wrinkled surface that enhances its surface area.
The cerebellum has an odd surface appearance that hides the fact that the cerebellar cortex, a layer of grey matter, makes up the majority of the structure. This layer's ridges are collectively referred to as folium.
