Answer:

Cleavage of a mineral is defined as the direction along which the mineral breaks over the flat mineral surface. It is directly dependent on the mineral's crystallographic structure.

Slaty cleavage refers to the cleavage that is commonly found in the low grade metamorphic rock slate. Here, the fine grained minerals are so closely spaced and the lines of weakness are all parallel to each other, that allows the minerals to break in fine and thin layers. During the time of formation of slate, the smaller fractures are formed due to the increasing pressure. When groundwater moves through these fractures it forms a weak zone due to which these slaty cleavage forms.

When the rocks undergoes deformation and changes in the pressure and temperature condition then the cleavages are formed on the mineral's surface. The calcite contains rhombohedral cleavage are considered to be the perfect cleavage. Whereas the cleavage in amphibole is uneven and comprised of two directions that intersect each other at 56° and 124°.

<h3>What is adaptations?</h3>

Adaptation can be described in different wats, one of it is the dynamic evolutionary process of natural selection which make the organisms to be able to live and carry out the life activities in their environment, which aid their evolutionary fitness.

In the case, above , it should be noted that , adaptations would help the grass be a successful pioneer species when major forest fire kills all of the plants in an area, the first plants to grow in the burned area are often types of grass is B.rapid reproduction and the ability to grow in sunny places.

Therefore option B is correct.

The options for the question are:

A.slow reproduction and the ability to grow in sunny places

B.rapid reproduction and the ability to grow in sunny places

C.slow reproduction and the ability to grow in shady places

D.rapid reproduction and the ability to grow in shady places

The Phoenician culture was different from most other ancient civilizations because their economy relied more heavily on trade than on agriculture.

<h3>How did the Phoenicians differ from other cultures?</h3>

The Phoenicians were different from other cultures because they were primarily interested in trade. As a result, they were able to establish a massive trading empire all around the Mediterranean that was integral to trade among the various ancient civilizations.

This was quite different from other ancient cultures because most of them preferred to focus on agriculture. For instance, the ancient Egyptians focused on farming along the Nile and the Mesopotamians focused on farming thanks to the Tigris and Euphrates.

The Phoenicians would then trade these agricultural goods for the other civilizations which is why they were so important.

In conclusion, the Phoenician culture was different from other ancient civilizations because their economy relied more heavily on trade than on agriculture.
