The correct answer is A. Plastic trash in the neighborhood park.
Explanation
The tragedy of the commons was a term used by Garrett Hardin to describe a situation in which several individuals motivated by personal interests destroy or undermine a common good even though none of them is convenient for this. Outcome. According to the above, the correct answer is A. "Plastic trash in the neighborhood park", because this describes the result of an individual action of several people, which is to throw garbage in the park and that as a result causes general damage in the community.

Answer:
Here's a better answer.There are multiple lines of evidence that provide support for common ancestry and evolution; this would be homologous features of anatomy and embryology and fossil records.
In comparative anatomy, there are many similarities between species because all life is related. Homology is similarities seen because of the ancestry of features or genes in an organism. Similarities can show descent from common ancestors and similarities can be seen in body structures, development, and DNA. Homologous structures are similar traits found in two different species that are the result of having a common ancestor. These structures are similar but may have different functions. An example of this might be the homologous structures in the limbs of humans, cats, whales, and birds. And then there are analogous structures, which similarly is that the structure of different species are similar because the trait is advantageous, not because they are related. An example of this is sharks and dolphins having similar fins. Along with anatomy is Embryology. Different species can have similar embryos because they come from a common ancestor. They may start with the same developmental plan but change drastically as they grow up. An example of this is seen in the early stages of development between fish and chicken embryos.
Next up, the fossil record provides evidence that supports common ancestry and evolution. The fossil record provides us with visual evidence for evolution. The fossil record directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today. The fossil record depicts evolutionary change over the past four billion years, which can be seen through transitional forms, increasing complexity of life, and geographical distribution. Transitional forms are fossils that show intermediate states between an ancestral species and its evolutionary descendants. Increasing complexity is seen as life on earth becomes more complex. That and geographic distribution which has been studied closely and found that the continents have moved over time and that the fossil record reflects this movement. Fossils of different animals can be found on different continents around the world due to continental drift.
Explanation:
The various pieces of evidence that support common ancestry are homologous organs, fossil records and embryological studies.
What is common ancestry?The phrase "common descent" in evolutionary biology refers to a particular group of species' shared ancestry. The creation of new species from an original population is a component of common descent. Two creatures are considered to be closely related if they have a recent common ancestor.
In contrast, molecular genetic techniques can also be used to establish shared ancestry from a single universal ancestor of all living things. Natural selection and other factors, such geographic isolation, are considered to have contributed to many speciation episodes during this development from a universal common ancestor.
According to the common ancestry idea, every living thing descended from a single progenitor. Hence, the Theory of Common Descent contributes to our understanding of why traits in species living in different geographic regions vary, why some traits are highly conserved across broad animal classifications (such as vertebrates or tetrapods), why seemingly unrelated species (such as birds and reptiles) share hereditary physical and genetic traits, and why successfully adapted organisms typically have more offspring.
Therefore, embryological studies, fossil studies and homologous organs can help in the study of common ancestry.

Skin color in a certain species of fish is inherited via a gene with four different alleles. Each allele confers a unit of color darkness such that having allele S1 confers one unit of color, S2 has two units, S3 has three units, and S4 confers four units. A fish of this type has the genotype S1, S3, and its mate has the genotype S2S4. What proportion of their offspring would be expected to have five units of color
Answers
Answer:
25% of the progeny with genotype S3S4 is expected to express 5 units of color
Explanation:
Available data:
Skin color in a certain species of fish is inherited via a gene with four different allelesallele S1 confers one unit of color, S2 has two units, S3 has three units, and S4 confers four units.Cross:
Parentals) S1 S3 x S2S4
Gametes) S1 S3 S2 S4
Punnett square) S1 S3
S2 S1S2 S2S3
S4 S1S4 S3S4
F1) 1/4 = 25% of the progeny is expected to be S1S2, expressing 3 units of color ⇒ allele S1 provides one unit, allele S2 provides two units of color
1/4 = 25% of the progeny is expected to be S2S3, expressing 5 units of color ⇒ allele S2 provides two units, allele S3 provides three units of color
1/4 = 25% of the progeny is expected to be S1S4, expressing 5 units of color ⇒ allele S1 provides one unit, allele S4 provides four units of color
1/4 = 25% of the progeny is expected to be S3S4, expressing 7 units of color ⇒ allele S3 provides three units, allele S4 provides four units of color
25% of the progeny with genotype S3S4 is expected to express 5 units of color

A. So each generation of DNA would have a different weight to distinguish them by.
B. To determine how the bacteria functioned with a heavier element.
C. To see how the heavy nitrogen affected their DNA.
D. So each generation of protein would have a different weight to distinguish them by.
Answers
Answer:
D. So each generation of DNA would have a different weight to distinguish them by.
I took the test
Meselson and Stahl performed an experiment to find out the semiconservative property of DNA and to differentiate the DNA weight of alternative generation both scientists used heavy nitrogen. Thus option A is correct.
What is the semiconservative property of DNA?When a double-stranded DNA undergoes replication, it results in the formation of 2 double-stranded DNAs and each newly formed DNA has one parental DNA strand and one new DNA strand and this is the semiconservative property of DNA.
Heavy nitrogen of media will appear in the newly synthesized DNA strand so each generation of DNA would have a different weight . So option A is correct.

Whiteflies are common pest insects found on cotton, tomato, poinsettia, and many other plants. Nymphs are translucent and mostly sessile, feeding on their host plant's phloem (sap) from the undersides of leaves. They undergo incomplete metamorphosis into winged adults. Because whitefly nymphs cannot escape predation by moving, you hypothesize that their translucent bodies make them hard to spot by predators. How could you directly test this hypothesis?
Answers
Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.
Explanation:
A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.

Answer:
a way to inform conservation efforts based on genetic information from species
Explanation:
Genetic studies in wildlife and captivity species provide significant information to understand aspects regarding the biology and ecology of species, especially endangered species. Many discoveries have been useful to solve several taxonomic issues, determine the risk of diseases, and explain reproductive problems, among other problems. What is even more important is that genetic knowledge helps to plan management programs and conservation. Together with other areas related to behavior and conservation, genetic knowledge provides the basis to carry out successful conservation strategies.

All organisms can use sunlight to make food. (False). Plants cannot make their own food. (False). How do plants prepare their own food?Plants prepare their own food with the process of photosynthesis which utilizes carbon dioxide and water and synthesizes glucose in the presence of sunlight.
Plants, some photosynthetic algae, and some bacteria prepare their own food with the help of sunlight. They have a photosystem that captures the energy of sunlight in the food production mechanism.
