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.

Answer:
Your answer is cytokinins.
Explanation:
Hydrogen atoms in compounds such as h2 and H2o are joined to the molecules with covalent bonds. This is where electrons are shared between the atoms in order to fill there valence shells.
As we mentioned before, hydrogen can only form one covalent bond because its 1s electron orbital holds a maximum of two electrons. Hydrogen can form either a polar covalent bond or a non polar covalent ( cause there is no electronegativity difference between the two molecules).
Water contain polar covalent bonds because the oxygen has a grater electronegativity than the hydrogen atom.
Answer;
-Citrus trees are angiosperms and dicots. Citrus tress have herbaceous or woody stems.
Explanation;
-Angiosperms are vascular flowering plants. They are divided into two classes: the monocotyledonous (monocots) and the dicotyledonous (dicots). This distinction is based on the number of cotyledons, the food storage structures in their seeds. Monocots have one cotyledon while the dicots have two.
-Citrus tree is an example of Angiosperm, dicotyledonous plant. Additionally citrus tree have herbaceous or woody stems.
