Explain why parallax was a problem in proving the heliocentric model of the solar system.
Copernicus himself asserted that the absence of parallax meant that the stars were far beyond the planets. The failure of heliocentrists to detect it proved nothing, whereas a successful detection would be strong evidence for heliocentrism.
What is heliocentric model?The astronomical model in which the Earth as well as planets revolve around the Sun at the center of the universe is known as heliocentrism. Historically, heliocentrism was opposition to geocentrism, which centered on the Earth.
Galileo wanted to believe that his new invention, the astronomical telescope, could assist him in proving that the Sun was the center of our solar system and that Earth was only one of many planets orbiting our star.
Copernicus himself claimed that the lack of parallax indicated that the stars were far beyond the planets.
Failure to detect it by heliocentrists proved nothing, whereas successful detection would be strong evidence for heliocentrism.
Thus, parallax was a problem in proving the heliocentric model of the solar system.

Differentiate between the three dose-response curves, and explain why these curves do not apply to individuals.
Answer:
LD-50: lethal dose 50%, dosage that causes death to 50% of the exposed population
ED-50: effective dose 50%, dosage that causes an effect in 50% of the observed subjects
TD-50: toxic dose 50%, dosage that is toxic to 50% of the observed subjects
These curves do not apply to individuals because it is hard to predict the dosage that will cause a response in an individual, and more practical to predict what percentage of a population will be affected by a certain dosage of a chemical.

Help me on this please
Explanation:
A.
The transpiration stream that passes through a plant may follow an apoplastic route, with low resistance to flow, or a cell-to-cell route, in which cellular membranes impede water flow. However, passage of water through membranes can be facilitated by aquaporins thereby decreasing resistance. We investigated the relationship between transpiration, which can be down-regulated by abscisic acid (ABA) or by high humidity, and the osmotic water permeability (Pos) of protoplasts. By using leaf protoplasts of wild-type (wt) Arabidopsis thaliana plants and of mutants that are low in ABA (aba1) or insensitive to ABA (abi1 and abi2), we found that protoplasts from aba1 and abi mutants have very low Pos values compared with those from wt plants when the plants are grown at 45% relative humidity. High values of Pos were found 3 h after the addition of ABA to the culture medium of aba1 plants; addition of ABA to abi plants did not restore the Pos to wt levels. There was no such increase in Pos when excised leaves of aba1 plants were treated with ABA. When the transpiration stream was attenuated by growing the plants at 85% relative humidity, the Pos of protoplasts from all plants (wt and mutants) was higher. We suggest that attenuation of the transpiration stream in whole plants is required for the up-regulation of the Pos of the membranes, and that this up-regulation, which does not require ABA, is mediated by the activation of aquaporins in the plasma membrane.
B.
The influence of abscisic acid (ABA) on carbon metabolism, rate of photorespiration, and the activity of the photorespiratory enzymes ribulose bisphosphate oxygenase and glycolate oxidase in 7-day-old barley seedlings (Hordeum vulgare L. var. Alfa) was investigated. Plants treated with ABA had enhanced incorporation of labeled carbon from 14CO2 into glycolic acid, glycine, and serine, while 14C incorporation into 3-phosphoglyceric acid and sugarphosphate esters was depressed. Parallel with this effect, treated plants showed a rise in activity of RuBP oxygenase and glycolic acid oxidase. The rate of photorespiration was increased twofold by ABA treatment at molar while the CO2-compensation point increased 46% and stomatal resistance increased more than twofold over control plants.

The correct pairing of DNA bases is C with G, and A with T. Therefore option D is correct.
DNA (deoxyribonucleic acid) is composed of nucleotides, which are made up of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
In DNA, the bases always pair up in a specific way known as complementary base pairing. The bases adenine (A) and thymine (T) form a pair, and cytosine (C) and guanine (G) form a pair.
This pairing is based on the specific hydrogen bonding interactions between the bases:
Adenine (A) always pairs with thymine (T) through two hydrogen bonds.
Cytosine (C) always pairs with guanine (G) through three hydrogen bonds.
This specific pairing of bases is crucial for DNA replication and the accurate transmission of genetic information during cell division and protein synthesis.
The pairing of DNA bases: (D) C with G, and A with T. This pairing reflects the complementary base pairing rules observed in DNA.

Answer:
I would prefer to have city water because you don't have to worry about it getting polluted unlike well water. The city water is maintained by the city while with the well water, you maintain it yourself. Even though it can be pricey, most people live in the city anyway, so there is easier access to it.
Explanation:
Answer:
Well Water
Explanation:
I would prefer well water, because city water had a lot of chemicals, and city water filters out minerals that are good for the body. Also, well water tastes ten times fresher than city water. Also, well water is easy to obtain if you already have a well, all you have to do is wither pump it up, or use a basket to scoop some out.
