Estuaries can experience fairly extreme changes in abiotic conditions. For example, estuaries can at different times be dominated by the ocean when freshwater input from upstream is minimal, or it can be freshwater dominated when there is a lot of flow coming into the estuary from upstream. This means that organisms that exist within estuaries must be able to tolerate a wide range of salinities. These are called euryhaline organisms. Estuary ecosystems also receive biotic inputs from both the ocean and from the upstream river. There are therefore a lot of scavengers that thrive within estuaries, such as crabs, mud prawns and clams. One primary producer group that is important for estuaries are mangroves, but they are not found in all estuaries. Estuaries act as important nursery areas for ocean fish, who come into the estuary to spawn.
Answer:
The oligosaccharide is assembled on the lipid carrier at the membrane of the ER
Explanation:
N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.
Answer: B) Light to Mechanical Energy
Explanation:
The correct alignment for a solar eclipse is <span>sun - moon - Earth. It is letter A.
>Solar Eclipse--only occurs when </span><span>Moon passes between Earth and Sun
>Its shadow has</span> two parts namely:
<span>1. Penumbra--<span>The Moon's faint outer shadow.
</span>2. Umbra---<span>The Moon's dark inner shadow.</span></span>
The presence of over 700 genes involved in height determination is an example of a polygenic trait.
<h3>What is a polygenic trait?</h3>
A polygenic trait refers to a trait that is determined by multiple genes rather than by only one gene. This is opposite to a monogenic trait that is determined by only one gene.
<h3>What are some examples of polygenic traits?</h3>
In humans, some examples of traits that are determined by multiple genes are:
- Height
- Hair color
- Skin color
Based on this, heigh is a polygenic trait.
