Answer:

b. cladophora

Explanation:

The cladophora algae is a type of green algae that grows attached to rocks or wood that are underwater. It forms short, rigid green filaments that branch, it's smell is similar to mushrooms. The cladophora is introduced in aquariums via contaminated plants or equipment, therefore to prevent it's formation it is necessary to clean everything before intoruducing it to the aquearium. This algae is so resistant once installed that usually the tank has to be re-started.

1.) You are studying P120, a protein of 120 KDa that is continuously synthesized in eukaryotic cells. Its cellular concentration
irina1246 [14]

Answer:

1. P120 is degraded in the 26S proteasome

2. The 26S proteasome has a major role in protein degradation and is critical for protein homeostasis

3. Cell cycle and DNA replication are cellular processes regulated by the Ras and NFkB pathways

Explanation:

The proliferation-associated nucleolar protein (p120) is a protein known to be expressed during the interphase of the cell cycle, specifically in G1 and early S phase, where any problem with DNA replication trigger a checkpoint, i.e., a molecular cascade of signaling events that suspend DNA replication until the problem is resolved. In mammalian cells, the 26S proteasome is responsible for catalyzing protein degradation of about 80% (or even more) of their proteins. The 26S proteasome acts to degrade rapidly misfolded and regulatory proteins involved in the cell cycle, thereby having a major role in protein homeostasis and in the control of cellular processes. It is for that reason that inhibitors that block 26S proteasome function have shown to be useful as therapeutic agents in diseases associated with the failure of protein degradation mechanisms (e.g., multiple myeloma). The NF-κB are highly conserved transcription factors capable of regulating different cellular processes including, among others, cellular growth, inflammatory responses and apoptosis. Moreover, the MAPK/ERK pathway is able to transduce different signals received on the cell surface to the nucleus. The MAPK/ERK pathway is activated when a singling molecule binds to a cell receptor which triggers a signaling cascade that ends when a transcription factor induces the expression of target genes, ultimately producing a response in the cell (for example, the progression through the cell cycle).

after the brain receives information from the body's sensory receptors, what is the next step in responding to this information?
Bumek [7]

The sensory receptors refer to the portions of the nervous system, which sense variations in the external or internal surroundings. The sensory input can be in various forms, comprising taste, pressure, light, sound, pH of blood, or levels of hormones, which are transformed into a signal and are transmitted to the brain or spinal cord.  

In the sensory centers of the brain, the barrage of information is integrated and a response is produced. The response, that is, a motor output refers to a signal conducted towards organs via motor neurons, which then transforms the signal into some kind of action, like changes in heart rate, movement, discharge of hormones, and others.
