Answer:
four trophic levels
Explanation:
All food chains and webs have at least two or three tropic levels. Generally, there are a maximum of four tropic levels. Many consumers feed at more than one tropic level.
Answer:
Anabolic reactions use ATP and small substrates as building blocks to synthesize larger molecules.
Explanation:
Anabolic reactions are part of metabolic pathways that occur inside the living cells. Anabolic reactions always form complex molecules from simpler substances. The formation of glucose from relatively simpler CO2 and H2O during the Calvin cycle is an example of the anabolic pathway. During anabolic pathways, the metabolic energy of ATP hydrolysis drives the endergonic reactions. Therefore, anabolic reactions consume ATP. Calvin cycle uses the ATP produced during light reactions of photosynthesis.
Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
In most cases, one uses tests whose size is equal to the significance level.

The answer to this question would be: Inhibited grief.
Inhibited grief happens when someone <span>does not display any sign of mourning. This kind of grief can cause a health problem like a stomach ache or a headache. It is important to resolve the grief when losing someone important so that grief doesn't come back as an unexplained medical problem.</span>
