Answer:

Option B, Observation 2

Explanation:

The four main observation of Darwin’s areas follows –  

Observation 1 – Variation occurs in the species with time leading to evolution. Offspring of two parents vary distinctly in traits such as height, color, weight etc. These variations are also affected by the surrounding environment

Observation 2-  

Based on observation 1, Darwin concluded that offspring inherit traits from their parents. These traits improve the odds of survival and only genetic traits will be passed. Traits developed in an individual due to environment will not be passed on.

Observation 3 –  

Offspring compete among themselves to survive.

Observation 4

The fittest among the competing species for survival will survive and pass on its traits to the next generation.

Since here the Pigeon breeders want to exemplify the looks (a genetic trait) of  parents to their offspring, observation 2 applies here

Hence, observation b is correct

Compare and contrast the two types of bonds
stepan [7]

Answer:

An ionic bond is formed between a metal and a non-metal. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.

Explanation:

There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.

Describe the movement of water particles in a wave
Elza [17]

Answer: Water waves are surface waters. Waved are created by energy that is passing through water particles. As the wave crest move, it causes water particles to move in a circular motion. Water don't travel in waves, waves energy trigger water movement which is driven by wind, this create friction between the wind and the water. The waves passes through the water but water particles remain in their formal position.

Explanation:

Water waves are surface waves in that they travel in circular direction due to energy created by the wave.
