The event that was dated using the most valid and reliable source is millipede appears.
<h3>What is a reliable source?</h3>
In science, reliable sources include those that provide strong evidence to prove a hypothesis is false or true. The most common reliable sources in science are:
- Data that was collected from experiments using the scientific method.
- Observations that are consistent.
- Peer-reviewed articles about a phenomenon.
- Evidence such as specimens, fossils, rocks, etc.
Based on this, the event that was dated using the most valid and reliable resource is the millipede appearance because this event was dated using fossils, which are a type of reliable source in science. Moreover, other sources such as history books or green plants are not reliable.

Answer:
Polar; hydrophobic (Ans. B)
Explanation:
Glycerophospholipids are known as the class of lipids which are found extensively in the biological membrane. They are usually consisting two regions of lipids which provide structure to the lipid bilayer in which the hydrophilic heads (polar) attaching outside to the cell and the hydrophobic tails (non-polar) pointing insides to the cell membrane.
Glycerophospholipids helps to provide permeability and fluidity to the membrane and also helps in the programmed cell death, and modulation of actions of membrane-bound enzymes.

Explanation:
A carbohydrate composed of two covalently bonded simple sugars is called a <u>disaccharide</u>.
Carbohydrates or sugars are one of the four main categories of the macromolecules that make up living things (the other three being nucleic acids, proteins and lipids). It can either be a simple sugar (sugar monomer or monosaccharide) or a polymer of simple sugars.
Carbohydrates are composed entirely of carbon, oxygen and hydrogen atoms. Simple sugars or monosaccharides contain six carbon atoms, twelve hydrogen atoms and six oxygen atoms. When two monosaccharides bond covalently, they form a disaccharide.
Some examples of disaccharides include:
- Sucrose or table sugar - It is made up of one glucose molecule and one fructose molecule
- Lactose or milk sugar - It is made up of one glucose and one galactose molecule
- Maltose or malt sugar - It is made up of two glucose molecules.
