Solar energy would have the greatest impact on the primary productivity.
Explanation:
The autotrophs are the primary producers which create organic compound by photosynthesis in the presence of sunlight.
The energy flow is initiated by autotrophs alone and energy flow in ecosystem is by the photosynthesis.
So the primary productivity depends upon the solar energy to perform photosynthesis and flow of energy in trophic level is maintained.
The organic compound as glucose is the source of energy for all consumers.
it is known that if primary productivity is imbalanced the whole food chain, trophic levels and ecosystem will be disturbed.
Answer:
This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.
Explanation:
During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.

Explanation:
Protein G belongs to a class of proteins involved in the transduction of cellular signals. It is an important mediator of metabolic pathways in the form of heterotrimer, with α, β and γ subunits, which, in the plasma membrane, is associated with GPCR receptors. When an extracellular signal binds to a GPCR (G protein-associated receptor) present on the plasma membrane of cells, G protein undergoes a conformational change capable of activating one of its subunits that is GTP-bound, making it able to alternate between one binding state with an inactive guanosine diphosphate (GDP), the other with an active guanosine triphosphate (GTP). This leads to a cascade of signaling events that result in the regulation of subsequent cell processes such as the release of second messengers such as cyclic AMP. Protein G, along with its receptor, transmits signals from hormones and neurotransmitters, controlling the metabolism of cellular machinery, such as contraction, transcription and secretion.
The hand and foot spa machines must be flushed with a solution of about 5% bleach and circulate the liquid through the system for at least 10 minutes. f. Leave the solution in the hand and foot spa machines overnight or at least 5-10 hours before draining the machines so that they are thoroughly sanitized . And make sure where u are keepin it should b very airy and dust free so that it doesn’t give the guess infections
