Many researchers assumed that protein was the genetic material because at the time, proteins were known to have greater structural complexity and variability than nucleic acids.
Proteins were thought to have more functional diversity and were thought to be better suited for carrying and transmitting genetic information. However, further research revealed that nucleic acids, specifically DNA, were the true carriers of genetic information. This was demonstrated through experiments such as the Hershey-Chase experiment, which showed that DNA, not protein, was responsible for transmitting genetic information in viruses.
Many researchers assumed that protein was the genetic material for several reasons:
1. Complexity: Proteins are composed of 20 different amino acids, while DNA is composed of only 4 nucleotide bases. Due to this higher complexity, researchers believed proteins could store more genetic information than DNA.
2. Structural variety: Proteins have diverse structures and functions, making them appear as suitable candidates for carrying genetic information. DNA, on the other hand, has a more uniform structure.
3. Early discoveries: Initial research on cellular components focused on proteins and their importance in cell function, leading scientists to believe that proteins were the genetic material.
In summary, researchers assumed that proteins were the genetic material due to their complexity, structural variety, and prominence in early scientific discoveries. However, further research, including experiments by Avery, MacLeod, and McCarty, as well as the Hershey-Chase experiment, eventually proved that DNA is the genetic material responsible for inheritance and the transmission of genetic information.

Compare the palisade layer and the spongy layer of the mesophyll. Of the two layer, which layer has more cells?
Answer:
Palisade cells are packed tightly together, and most of the plant's photosynthesis is carried out in this sub-tissue. Moreover, cells in palisade mesophyll have a characteristic cylindrical shape and many chloroplasts. In spongy mesophyll cells, there are many air spaces, and the cells have slightly thinner cell walls.

What evidence from the study supports the hypothesis that dogs might use a magnetic sense to navigate?
Answer:
Yes.
Explanation:
Yes, a new research indicates that dogs might use a magnetic sense to navigate. Dogs has world class nose which helps them to navigate to their destination but it also has a magnetic compass that helps them in navigation. The dogs use magnetic field of the earth to find out shortcut ways in the unknown land or terrain so the hypothesis is right that dogs used magnetic sense for navigation.

Explain the 5 ways to reach Hardy-Weinberg equilibrium, does this mean evolution is occurring?
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).
What can you conclude about the effect of exercise on breath rate? Why is this so?
Explanation:
With exercise, cells need more oxygen, so the breath rate increases to provide the oxygen needed
Name one adaptation that allows desert plants to survive with little water?
Answer:
stomata
Explanation:
This adaptation helps cacti reduce water loss by keeping the hot, dry wind from blowing directly across the stomata. The leaves and stems of many desert plants have a thick, waxy covering.
Write a small paragraph explaining how metamorphic rocks form and what they are like.
Include the following words in your paragraph:
Heat
Pressure
Context and regional metamorphism
Foliated
Non foliated
Answer:
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Bacteria perform nitrogen fixation
More bacteria perform nitrification,
Nitrogen, in usable form, is taken up by plants,
and assimilated into their proteins (becoming

Explanation:
The appendix, an extension of the large intestine appears, although this is debated, to have little
function in humans. What is the appendix an example of in terms of evidence for evolution?
Answer: Vestigial organ
Explanation:
Vestigial organs are those organs which were functional in ancestral organisms belonging to the same species but due to the course of evolution of body forms they become non-functional. They can be found in the body either in the same form as used to appear in the ancestors or in rudimentary or degenerated forms.
The human appendix is one of the examples of vestigial organs. It looks like a narrow tube which forms a link with a colon of the large intestine. It was functional in human herbivorous ancestors as it used to help in digestion of variety of vegetables and other plant products. The change of diet along with due course of evolution caused the appendix to become useless. But the appendix physical form remained the same in humans.

respiration is a ____________ reaction on which sugar is oxidized to produce energy
Answer:
chemical
Explanation:
Respiration is a redox reaction on which sugar is oxidized to produce energy .
What is respiration?Cellular respiration is a sequence of chemical events that break down glucose to produce ATP, which can then be utilized as energy to power a variety of reactions throughout the body. Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.
Animals and humans use breathing to get the oxygen they need for cellular respiration. In order to create ATP, the nutrients you absorb through food must be broken down by the oxygen you breathe, while carbon dioxide and water are generated as waste products.
