Answer:
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons.
Explanation:
It releases bound oxygen into your body's tissues.
The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
Answer:
You need to know how the structures of plant tissues and organs are directly related to their roles in physiological processes.
Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.
Physiological processes are limited to photosynthesis, cellular respiration, transpiration, and reproduction.
Plant tissues are limited to meristematic, ground, dermal and vascular tissues.
Plant structures are limited to cambium, guard cells, phloem, seed, stomata and xylem.
