Answer:
bilateral symmetry
Explanation:
The evolutionary trait that is found in the most classes of invertebrates is bilateral symmetry. Bilateral symmetry is present in all classes of invertebrates shown on the phylogenetic tree, including mollusks, annelids, and arthropods. Radial symmetry, on the other hand, is only found in the cnidarians, and true tissues are only found in the deuterostomes. Therefore, bilateral symmetry is the trait that is found in the most classes of invertebrates.

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply. (10 points)
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals. By adding genes to an animal's DNA, the animal can be made to produce milk or meat containing vital nutrients that would not be found naturally in those products. This provides a greater amount of nutrients per serving of milk or meat.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
In the future, doctors may be able to evaluate your DNA to check for genetic markers related to specific medical conditions or harmful reactions to medications. Your personalized genetic profile could be kept on record and referred to in order to develop personal medical treatment based on your unique DNA sequencing. Scientists have found that just small variations in a specific section of your DNA can help determine how well some medications can work for you or if they would be beneficial at all.
Would you want to have your DNA profile kept in your medical record as a reference for your doctors? Explain your answer. (2 points)

Describe how the availability of this technology might affect the frequency of genetic diseases in individuals and populations. (3 points)
Answers
Answer:
1. It should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. There are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but I can't think of an example where the fears didn't turn out to be baseless.
2. Yes. First, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. The pros involve better medical treatment. The cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. Looking at DNA markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. And OK, actually I suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency.

How does the sperm of an angiosperm reach the egg?
Select one:
A. usually via an insect, which places sperm in the ovary while probing for nectar
B. via the pollen tube that grows from the pollen grain through the carpel tissues to the ovule
C. by actively swimming down through the style to the egg
D. via the pollen tube that grows from the ovule to reach the pollen grain on the stigma
Answers
The sperm of an angiosperm reach the egg via the pollen tube that grows from the pollen grain through the carpel tissues to the ovule.
Hence, the correct answer is option B.
Pollen is a fine powder that seed plants produce. Pollen grains (extremely reduced microgametophytes), which create male gametes, make up this substance (sperm cells). In the process of moving from the stamens to the pistil of flowering plants or from the male cone to the female cone of gymnosperms, gametophytes in pollen grains are shielded by a tough coating comprised of sporopollenin.
When pollen touches a pistil or female cone that is compatible with it, it germinates and creates a pollen tube that carries the sperm to the ovule that houses the female gametophyte. Pollen grains are so tiny that they must be magnified to be seen in detail. Paleoecology, palaeontology, archaeology, and forensics all benefit greatly from the study of pollen, which is known as palynology.

Based on your understanding of nucleic acids, what type of bonds form between the CRISPR/guide RNA molecule and the target DNA
Answers
Answer:
The single guide RNA forms hydrogen bonds with DNA, while Cas9 hydrolyzes phosphodiester bonds
Explanation:
The base pairing between nucleic acid strands (either DNA or RNA) is through hydrogen bonds between nucleotide bases. In DNA, Adenine always forms two hydrogen bonds with Thymine, while Guanine always forms three hydrogen bonds only with Cytosine. Moreover, adjacent nucleotides in the same strand are covalently linked by phosphodiester bonds (i.e., covalent bonds between the 5' phosphate group of one nucleotide and the 3'-OH group of another). The CRISPR/Cas9 genome editing systems make use of single-guide RNAs (sgRNAs) that interact with DNA through hydrogen bonds. These sgRNAs have perfect complementarity to the target DNAs in order to bind them. On the other hand, Cas9 is an enzyme that hydrolyzes phosphodiester bonds in both DNA strands very precisely and accurately by using a sgRNA complementary to a specific DNA sequence.

Answers
Answer:
Amino acids and Proteins
Explanation:
Plants as well as other living organisms require certain nutrients for their growth and development. One major inorganic nutrient that is needed by plants is NITROGEN, obtained in its compound form called nitrates. Nitrogen is necessary component for building amino acids and proteins in the cell because nitrogen is an integral element in the structure of AMINO ACIDS. Nitrogen makes up the amine functional group of amino acids (NH2).
Hence, If there were no nitrogen compounds in the soil, the most immediate effect on plants growing in that soil would be difficulty in synthesizing AMINO ACIDS and subsequently PROTEINS.
