Answer: Ptolemaic system, also called geocentric system or geocentric model, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about 150 CE and recorded by him in his Almagest and Planetary Hypotheses. The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that Earth is stationary and at the centre of the universe. The “natural” expectation for ancient societies was that the heavenly bodies (Sun, Moon, planets, and stars) must travel in uniform motion along the most “perfect” path possible, a circle. However, the paths of the Sun, Moon, and planets as observed from Earth are not circular. Ptolemy’s model explained this “imperfection” by postulating that the apparently irregular movements were a combination of several regular circular motions seen in perspective from a stationary Earth.

Which organelle is found in both eukaryotic cells and prokaryotic cells:
Ludmilka [50]

Answer:

c. Ribosomes

Explanation:

Ribosomes can be found in eukaryotic and prokaryotic cells.  In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm.  In both cells, ribosomes intertwine into an RNA molecule and form polysomes.

Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.

Should the FDA should give Aquabounty permission to grow and sell transgenic salmon? Why or why not?
True [87]

Answer:

Yes it should be approved

Explanation:

The FDA should give Aquabounty permission to grow and sell transgenic salmon because studies have shown that transgenic salmons which are genetically modified are harmless. This finding has allayed the fears of the people. Permission to grow and sell this type of salmons will make it easier for transportation to other parts of the country because it doesn’t necessarily have to come from the sea. It also ensures there is increased availability of the products all over the country.

What is the most important factor that determines the rate of diffusion in biological systems?
miv72 [106K]
The factors that determines the rate of diffusion in the biological system include: temperature, size of the particles, diffusion distance and concentration gradients. Of all these factors, the most important  one is the TEMPERATURE.
The relationship between temperature and the rate of diffusion is a direct one, that is, the higher the temperature the higher the rate of diffusion and vice versa. At high temperature the molecules in the particles move faster because they have higher amount of energy.
