Answer:
The cork cambium is a natural insulator that protects woody plants from an hostile environment.
Explanation:
The cork Cambium is a tissue that belongs to the epidermis, it is responsible for the secundary growth in the plant and replaces the epidermis in roots and stems. The cork cambium also protects the plant from overhydration, it is waterproof and has really selective ways to let the water into the plant (apoplastic and symplastic pathway).
There is some special plants in the coast of the tropical area called mangrooves, these plants has really specialized cork cambium that controls not only the water levels but also the salt levels into the plant.
The cork cambium is really important because protects and regulates the plant and its environment.
Answer:
Mafic -- the formation of the minerals begins anew upon melting.
Explanation:
Mafic minerals set at increased temperatures, which is there in Bowen's Reaction Series. Therefore, rocks collected of mafic minerals are designed at increased temperatures. They are originated in sites deep within the earth and also in tectonic dispersal environments, like the seafloor. Mafic magmas are generally formed at dispersal centers, and signify material which is recently distinguished from the greater mantle. Mutual mafic rocks comprise basalt and gabbro. Mafic rock, in geology, igneous rock that is subjugated by the silicates pyroxene, amphibole, olivine, and mica. These minerals are high in magnesium and ferric oxides, and their presence gives mafic rock its characteristic dark colour.
ANSWER: B: ONE OF THE SPIRAL ARMS OF THE MILKY WAY
Explanation: There are many arms to every galaxy, in our case, the Milky Way. To each spiral arm is one solar system, which is also why it so difficult to explore space.
Answer:
False
Explanation:
The sequence of amino acids in a protein is determined by the DNA and the structure of protein thus formed is a linear sequence. These linear structures undergo structural changes due to the formation of bonds between the constituent molecules.
When bonds are formed by the interactions between the CO group of one chain and the -H group which forms the backbone is known as the secondary structures. Two types of arrangements arise of this that is the helical and pleated sheet.
When the bonds are formed between the side groups or the R group of the amino acid therefore the amino acid structure formed is known as the tertiary structure.
Thus, false is the correct answer.
