Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
The movement of molecules, specifically water and any solutes, is vital to understand in light of plant processes. This will be more or less a quick review of several guiding principles of water motion in reference to plants.
The orientation of a plant or other organism in response to light, either toward the source of light >positive phototropism<span> or away from it ></span>negative phototropism
Answer:
The correct answer is - strata spinosum and strata basale.
Explanation:
The two strata of epidermis that are prone to the cancer are stratum basale and stratum spinosum. The stratum basale is the major stratum layer as it is only layer that can divide and mitotically active.
The other major layer that is succeptible to cancer is spinosum as it allows the maturation of the keratinocytes. The major culprit is UV light, however other causes such as radiation and arsenic can also cause cancer.
Thus, the correct answer is - strata spinosum and strata basale.
The nutrients from the soil is taken up by the roots
to be distributed to the entire plant. The plant absorbs the nutrients into its
cells and utilized by the leaves, stem, trunk. They are also used to grow
flowers and to bare fruits.
Moreover, the nutrients are divided into two groups;
first the macronutrients which is needed by the plants in large amount such as
nitrogen, phosphorus, potassium, calcium, magnesium and sulfur. Second group is
the micronutrients, needed in tiny amounts that include zinc, copper,
manganese, boron, iron, sodium and cobalt. These two groups are essential for
normal plant growth and development.
