Answer:
metamorphic rock
Explanation:
metamorphic rock simply means that the rocks have been geophysically altered. heat is always a primary source for alteratino of rock so the heat ofmolten rock generated by hot spots can easily cause an abundance of metamorphic rocks within the system
The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.
Explanation:
Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".

Answer:
A. Transport of materials in xylem
Xylem tissue helps in the transport of water and minerals
Water is transported upwards from roots to aerial parts of plants
Transport in xylem requires physical forces such as transpiration pull.
B. Transport of materials in phloem
Phloem tissue helps in the transport of food.
Transport of food in phloem requires energy in the form of ATP.
Food is transported in both upward and downward directions.
Depending on whether the animals are in nature or in a home environment, the factors that contribute to animals being exposed to toxins are man-made. Factories contaminate air and water. Combustion from engines pollutes the air. Garbage that is disposed contaminates the air, water and land. Often times, the lure of food for any animal, is what brings the animal into closer human contact, thus increasing the exposure to toxins. For a pet, the home environment and the decisions the pet owner takes to have chemicals like cleaners, fertilizers or pesticides and like motor oil increase exposure to toxins.
Individuals can prevent exposure for themselves and their pets by decreasing the use of motor vehicles, reducing the amount of garbage and trash produced, being a informed consumer who attempts to purchase more organic, Earth and animal friendly goods and services. Boycott corporations which contribute to the decline of the environment and increase exposure to these toxins. Other simpler ways, in environments with smog or other industrial pollutants, wearing clothing that covers most of the body, including breathing masks, gloves and glasses or goggles.
