B) Presence of a tidal range i believe.
Correction there are six and here they are:
species, biosphere, population, ecosystem, biome and community
Hope this helps
<span>Breakwaters, seawalls, and groins are all examples of shoreline structures.
</span>
Shoreline structures are built with the purpose to change ocean waves, sand movements and currents. Breakwaters are built to minimise the intensity of wave action reducing erosion in the coast or and creating a safe harbourage for ports. A seawall is a defence wall constructed to protect human habitation, or other areas of human interest, from the action of tides or waves maintaining the coastal area where the wall is unchanged. <span>A </span>groin structure<span> built from an ocean shore perpendicular to the shoreline</span><span> that stops the water flow and limits </span>sediment's movement<span>. It is constructed to prevent great movement of sediments and erosion.</span>
Answer:
Hello! Here are the answers:
- Chromosomes are a highly condensed form of a combination of DNA and protein called chromatin. DNA strands (negatively charged) are tightly wound around these proteins called histones (positively charged) to form chromosomes.
- Mechanism genes code for for proteins that govern life processes. These genes or portions of DNA are called exons. DNA segments between these exons are called introns that strictly code for regulatory proteins and also contain genetic regulatory elements (DNA sequences that control gene expression).
- Gene expression is the process of translation of DNA sequences into proteins. The genetic code is the nucleotide sequence in the DNA itself that codes for different amino acids that combine together to form a functional protein.
Explanation:
* 2. The intronic regions are misleadingly referred to as "junk DNA" but introns code for crucial regulatory elements that control gene expression.
* 3. The genetic code determines the sequence of amino acids in various proteins.
