Which describes the geocentric model of the solar system?
Earth is at the center. The sun and all other planets orbit Earth.
Within the geocentric system, the Earth is taken into consideration to be the middle of the sun device. The Moon, the planets, the solar, and the celebs all rotate across the Earth with uniform round motion. They compose the heavens, which are taken into consideration to be airy and unchanging.
Geocentric model, any concept of the shape of the sun device or the universe in which Earth is assumed to be in the middle of it all. The most especially evolved geocentric version turned into that of Ptolemy of Alexandria 2d century CE. An astronomer named Eudoxus created the primary model of a geocentric universe around 380 B.C. Eudoxus designed his model of the universe as a chain of cosmic spheres containing the stars, the solar, and the moon all built around the Earth at its center.

Protein is the correct answer
A biologist discovers a new signal transduction pathway in fruit flies that involves a protein kinase cascade. As part of a grant proposal he writes to obtain funding for further work on this pathway, the biologist proposes research to look for phosphatase enzymes. Why?.
Phosphatases are regulators of signal transduction pathways.
The biologist must find the enzymes that control the signaling cascade by removing phosphate groups from molecules. Protein phosphatases can act as both immediate and delayed signal transduction regulators, attenuating or boosting signaling.
Protein kinases and phosphatases are enzymes that catalyze the transfer of phosphate from one substrate to another. A protein kinase catalyzes the -phosphate transfer from ATP (or GTP) to its protein substrates, whereas a protein phosphatase catalyzes the phosphate transfer from a phosphoprotein to a water molecule. Despite the fact that both families of enzymes are phosphotransferases, they catalyze opposite processes to modify the structures and activities of numerous prokaryotic cellular proteins and eukaryotic cells.

What is semi-permeable membrane?
Only some molecules can flow across a semipermeable membrane, which prevents the passage of other molecules. In essence, a semipermeable barrier serves as a filter. Different kinds of semipermeable membranes can filter out molecules of different sizes. A biological or synthetic material can be used to create a semipermeable membrane.
Diffusion is the overall transfer of anything (such as atoms, ions, molecules, or energy) from a region of higher concentration to one of lower concentration. Diffusion is fueled by a gradient in the chemical potential or Gibbs free energy. It is possible for molecules to diffuse "uphill" from a region of lower concentration to one of higher concentration, similar to spinodal breakdown.

how is the energy stored in polysaccharides mobilised?
Plants store carbohydrates in long polysaccharides chains called starch, while animals store carbohydrates as the molecule glycogen. These large polysaccharides contain many chemical bonds and therefore store a lot of chemical energy.
Since these large polysaccharides have many chemical bonds, they can store a lot of chemical energy. Whenever these compounds are decomposed all through metabolic activities, the energy in the chemical bonds is released and can be used by cells.
What is a polysaccharide?Polysaccharides are important types of biomolecules. They are long chains of carbohydrate molecules made up of many smaller monosaccharides.
Many polysaccharides are used by organisms to store energy. While energy-producing enzymes only work on monosaccharides stored in polysaccharides, polysaccharides generally fold together and they may contain many monosaccharides in a dense area.
The high energy carbon-hydrogen covalent bonds between the monomers in a polysaccharide store the energy.
The breaking of these bonds is what causes the energy used to generate ATP to be released. The higher the energy content of the polysaccharide, the more of these bonds there are.
Thus, this way, the energy stored in polysaccharides is mobilized.

Asking questions to check your perception is called d. direct perception.
According to the direct perception theory, the information that is required for perception is external to the observer, which means that one can directly sense an object established on the properties of the distal stimulation alone, unassisted by inference, recollections, the building of illustrations, or the effect of other cognitive operations.
For example, when an ape watches other apes advancing into a tree, grasping something, and then placing it into its mouth, this should be instantly sensed as feeding without the necessity for thought. The Intelligibility of this conduct is not only defined by species-specific biology but instead allowed by the attributes of the circumstances.
