Scientists build models based on what they know from previous research to derive testable hypotheses.Independently, both Watson and Crick and their competitor Linus Pauling constructed an incorrect triple-helix model with the nitrogenous bases arranged so they were on the exterior of the molecule and the phosphate groups on the interior. What evidence caused Watson and Crick to revise their model (CHOOSE 2)
Answer:
Hello. You didn't show the answer options, but we can consider that Watson and Crick revised the DNA model after seeing DNA images taken through Franklin's x-ray and by observing the pairing of the nitrogenous bases.
Explanation:
For a long time it was believed that the DNA molecule had 3 strands, instead of two, however this information was inaccurate and although defended by some scholars it was somewhat controversial and showed the need for further investigation. With that in mind, Watson and Crick decided that it was necessary to evaluate DNA in a three-dimensional way and therefore, they obtained x-ray images of DNA molecules, taken by Franklin. In these images, it was possible to notice that the DNA had two strands, instead of three. To prove this discovery, Watson and Crick analyzed the nitrogenous bases discovered by Chargaff and the way they were paired, coming to the conclusion that the DNA had two strands.

1. Syntrophs
2. Autotrophs
3. Chemolithotrophs
4. Mixotrophs
5. Heterotrophs
6. Phototrophs
7. Chemotrophs
Answer:
a. mixotrophs
b. autotrophs
c. syntrophs
d. phototrophs
e. heterotrophs
f. chemolithotrophs
g. chemotrophs
Explanation:
Autotrophs are organisms that can synthesize their own food using carbon dioxide (CO2) and water (e.g., algae, cyanobacteria, plants, etc). Syntrophs are organisms that utilize products from other organisms (e.g., mites that consume human dead-skin). Phototrophs are organisms that synthesize their own food by using the energy provided by sunlight (e.g., green plants). Heterotrophs are organisms that cannot synthesize their own food, obtaining energy and nutrients by consuming other organisms (e.g., animals). Mixotrophs are flexible organisms that obtain their food by using a mix of different sources of energy and carbon. Protists that combine autotrophy and heterotrophy are considered mixotrophs. Chemotrophs are organisms that obtain energy by the oxidation of electron donors from the environment, by using both organic sources (chemoorganotrophs) and inorganic sources (chemolithotrophs). Examples of chemolithotrophs include sulfur/iron-oxidizing bacteria, while chemoorganotrophs include the most known bacteria and archaea.

What is the difference between learned behavior and an inherited behavior?
Answer:
Learned behavior is a trait that something learned to do, like how to read or ride a bike. Inherited behavior is instictual and naturally comes to an organism at birth, like sleeping or eating.
types of adaptation and explain
Answer:
The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations. Most organisms have combinations of all these types.
Explanation:
Living things are adapted to the habitat they live in. This is because they have special features that help them to survive. The development of these special features is the result of evolution due to gene mutation. These mutations aid in the survival and reproduction and passes on from one generation to the other.
Answer:
Behavioural-Physiological-Structural
Explanation:
Behavioural - responses made by an organism that help it to survive/reproduce.
Physiological - a body process that helps an organism to survive/reproduce.
Structural - a feature of an organism's body that helps it to survive/reproduce.

If Earthquake X measured 1 and Earthquake Y measured 3 on the Richter scale, then
A. Earthquake Y had three times the ground motion of Earthquake X.
B. Earthquake Y had ten times the ground motion of Earthquake X.
C. Earthquake Y had 100 times the ground motion of Earthquake X.
D. None of the above
Answer: C. Earthquake Y had 100 times the ground motion of Earthquake X.
Explanation:
The Richter Scale is used to measure the intensity of earthquakes by comparing them to each other. There are 10 levels to the Richter Scale and each level is 10 times more intense than the last level.
If earthquake X measured 1 on the scale and earthquake Y measured 3, then Y was (10 * 10) times the intensity of X thereby placing Y at 100 times the intensity and ground motion of earthquake X.

6.) State the principle of dominance? I
Answer:
Please find the answer below
Explanation:
According to the convener, Gregor Mendel, the law of dominance states that one allele of a gene called DOMINANT ALLELE possess the ability to mask the phenotypic expression of another allele called RECESSIVE allele.
This law explains that in a heterozygous state of a gene, the dominant allele will always be expressed over the other. For example, in the trait of height, if T is tall and dominant, it will mask the allele of the other phenotype.

compare and contrast prophase of mitosis and prophase of meiosis1?
Answer:
The homologous chromosomes pair together in prophase 1 of meiosis, but they do not during prophase 1 of mitosis. This is achieved by a process known as synapsis, where the similar chromosomes pair according to sequence similarity. The homologous chromosomes are held together by a protein structure known as the synaptonemal complex in a chromosome body known as a tetrad (because it contains 4 replicated chromosomes known as chromatids) or bivalent (if the organism is diploid). This pairing during prophase 1 of meiosis allows recombination to take place between the homologous chromosomes. This occurs early during prophase but the manifestation of recombination only becomes visible during the later stages of prophase 1 and in metaphase 1. Because the chromosomes adopt different structures during prophase 1 of meiosis, this stage is sub-divided into 5 stages: leptotene, zygotene, packytene, diplotene and diakinesis. It is during diplotene and diakinesis that the physical manifestation of recombination can be seen. This is the presence of chiasmata (chiasma, singular). These are the sites where recombination, or exchanges between homologous chromosomes, has taken place. By the end of prophase 1, it is only the chiasmata that holds the homologous chromosomes together. This constriction make the tetrads adopt a variety of structures, the shape of which depends upon the number of chiasmata formed. The tetrads stay in this conformation until metaphase 1. Synapsis, the formation of the synaptonemal complex, the formation of chiasmata does not take place during prophase 1 of mitosis and these processes represent the major differences between prophase of the two nuclear divisions.
