If reproduction didn't exist, all species would eventually go extinct.
Answer:A. club
Explanation:
Fungi are eukaryotic organisms .they are feed on dead, decaying matter because they lack chloroplast. Most fungi are parasitic or symbiotic.
Fungi lacks root, stem and leaves. They however posses threadlike filaments called hyphae, which forms a larger mass called mycellium. Fungi reproduce asexually by spores. The classification of fungi are;
#zygomycetes, also called conjugation fungi .eg bread mold
#ascomycetes, also called sac fungi eg baker's yeast
#deuteromycota, also called imperfect fungi eg penicillium
#basidiomycetes .they are the commonly known mushrooms. They grow on wood and trees. Most of their species are edible. They are also called club fungi
Insects, and some other invertebrates, exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae. Tracheae open to the outside through small holes called spiracles.
Answer:
if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)
Explanation:
The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.
Litostatic pressure originates from the weight of materials in the interior of the crust.
Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.
There are different types of metamorphism.
Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.
Classification of the metamorphic rocks according to their structure:
- Granulation
- Recrystallization
- Metasomatism
- Massive
- Foliation
Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.
<em>According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation. </em>
