Energy in biology falls into two categories. Kinetic energy (aka cellular work) includes solute
transport, motion, and endergonic chemical reactions. Potential energy is the energy of position and
is an important tool to store energy in biology. Potential energy in biology includes covalent bonds
and chemical gradients. Which of the following is evidence of the potential energy of covalent
chemical bonds?
a
Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
All of the other choices are evidence of the potential energy of covalent bonds.
O Light and heat are released when cellulose (wood) is burned.
Exergonic hydrolysis of ATP powers motor proteins.
Answer:
A. Triglycerides (CiaH36O2l3 store about twice as much energy as polysaccharides (CH2O)
Explanation:
Energy, as stated in this question, can be of two types namely: kinetic energy and potential energy. Kinetic energy is the energy due to motion i.e the energy used to transport solute etc.
On the other hand, potential energy is the energy due to position like the energy stored in the covalent bonds of a molecule. Based on this question, the fact that triglycerides (a type of lipid) store about twice as much energy as polysaccharides (carbohydrate) is evidence that POTENTIAL ENERGY is stored in covalent bonds.

A ______________ stain uses only one dye to enable the viewer to observe the size, shape, or arrangement of cells A ______________ stain uses only one dye to enable the viewer to observe the size, shape, or arrangement of cells Gram stain Simple stain Endospore stain Capsule stain
Answer:
Simple.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell staining can be defined as a method used by scientists to view the cells of living organisms and its cellular components with the aid of microscope.
A simple stain uses only one dye to enable the viewer to observe the size, shape, or arrangement of cells. It typically involves the process of soaking a smear (thin film of living microorganisms) in dye and then rinsing it afterwards in order to visualize size, shape or arrangement of cells and other cell organelles such as mitochondria, cytoplasm, nucleus, golgi apparatus etc.

Complete question:
A population of bats feeds on flying insects. Some of these bats have a gene that results in much stronger flight muscles than those of the other bats in the area. Explain how this variation could lead to evolutionary change within this species of bat. In your answer, be sure to include an explanation of
Competition within the bat populationSurvival of various individuals within the bat populationHow the frequency of the trait for stronger flight muscles would be expected to change within the bat population over time.Answer:
Animals with the gene of stronger muscles are better competitors, which means more chances to survive and to reproduce. When they reproduce they pass the gene to the progeny, increasing the allele frequency in the population, probably until fixating it.
Explanation:
Within a population occurs competition among individuals for different resources such a food, territory, refuge, access to females, among others. Feeding habits result in a very important factor that models the species structures, and that might even result in the differentiation of the species into subspecies. Competition for food acts as pressure for animals leading them to develop new strategies for food access. In the exposed example, one of these new strategies is related to a better flight, which is possible due to the gene that results in much stronger flight muscles. Individuals that develop stronger flight muscles are more competitive and probably improve their social status, not only because they can get access to more and better food, but also because this means a better genetic charge which makes them better for mating. These animals have more chances to survive and reproduce: they are stronger and they feed better than the other individuals. The stronger flight muscles are not only useful for feeding, but also for avoiding predators, and for competition. Animals with this gene probably live longer.
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. The mutation in the gene of muscle development turns to be beneficial for the species. Animals that carry the gene have more chances to mate and reproduce, and hence to pass the gene to the progeny. In this way, the allelic frequency will increase within the bat population over time.
The study of an environment is called ecology.
The difference in the genes in the given population is called variation and this variation leads to the formation of a new character that has a higher chance of surviving in nature.
These variants have the tendency to choose naturally for the environmental condition.
According to the question, if the bats have the stronger muscle to fly they will reach the prey easily and eat them, before the slow-flying.
This leads to increase competition and the inferior species will extinct due to the higher rate of competition.
Hence, the fast-flying bats are selected naturally and inferior species will extinct.

When reproducing, Robins (a species of bird) typically lay four eggs. Laying more eggs might result in malnourished chicks and laying fewer eggs might result in no viable offspring. This is an example of
Answer:
stabilizing selection
Explanation:
The illustration is an example of stabilizing selection.
Stabilizing selection is an evolutionary mechanism in which the extremes of traits are selected against, leading to an increase in the frequency of such traits in the population.
Laying too many eggs would lead to reduced fitness of the population of the bird as a result of malnutrition while laying too few eggs would lead to a reduction in the population. Reproduction needs to be optimized for maximum fitness.
There are different types of natural selection. One of them is stabilizing selection that favors the intermediate phenotype. The exposed scenario is an example of stabilizing selection.
Balancing selection, also called Stabilizing selection, decreases the frequency of individuals with extreme traits, and favors individual that exhibit medium-range characteristics, that gets to survive. Selective pressure is against h0m0zyg0tes, promoting genetic diversity. Genes expressing extreme characteristics in a h0m0zyg0sis are kept in a heter0zyg0us state, as a favorable adaptation to environmental conditions. In a graph, you will see that
→ The curve gets higher and thinner in the middle of the horizontal axe, indicating an increase in the heter0zyg0us genotype frequency.
→ The tails of the curve that coincides with h0m0zyg0us dominant and recessive genotypes frequencies will be near zero.
In the exposed example,
laying more than four eggs and less than four eggs are extreme phenotypes. laying four eggs is an intermediate favored phenotype.
The intermediate phenotype results in the species' fitness increase, so it is favored by natural selection.
Laying four eggs leads to well-nourished chicks, and all of them get to survive. Parents ensure their reproductive success.

What would happen if we did not have Start Codons?
A. Polypeptide chains would continue to grow
B. Protein synthesis wouldn't occur
C. Amino acids would bind to tRNA
D. mRNA would form a double strand
Answer:b
Explanation:
Without the presence of start codons, Protein synthesis would not occur. Option B is correct.
In the synthesis of proteins, codons are referred to as the genetic codes that represent each of the amino acids that form the protein. These codes are in groups of three base nucleotides. The mRNA or messenger is the carrier of the code that will be responsible for the production of a certain protein.
A start codon is a three-base pair of nucleotides that holds the code needed to initiate the protein synthesis. The most common start codon in humans is AUG. Without the start codons, mRNA would still be taken to the ribosomes for protein synthesis but the process would not be able to begin.

Answer:
its the the first option
Explanation:
This is because plants fix carbon dioxide from the atmosphere through photosynthesis. They produce sugar for food from the CO2.
Answer:It would be A i believe
Explanation: The enzyme RuBisCO is an organic compound that incorporates carbon dioxide. The organic molecule is reduced in stage 2. RuBP, the enzyme that begins the cycle, is regenerated in stage 3 so that it can begin the cycle. In short, fixing six carbon atoms from CO2 requires six turns of the Calvin cycle.
2. Interpret Graphs As you move up the y-axis, is the rate of photosynthesis
increasing or decreasing? As you move along the x-axis to the right, is the light
intensity increasing or decreasing?
Answer:
It depends on the graph movement.
Explanation:
If the light intensity is present on the x-axis and the rate of photosynthesis is located on the y-axis, then both the rate of photosynthesis and intensity of light are increasing because the graph moves upward which means the rate of photosynthesis increases with the increasing of light intensity. So if you moves from upward to downward, the rate of photosynthesis decreases with the increasing of light intensity.
