D. logos and cosmos because it was cut off in the pic NEED ANSWER HURRY
Answers
The correct answer is A. Ethos and Logos
Explanation:
The purpose of rhetoric is to use strategies to convince the audience. In the case of ethos, this relies on the reputation or prestige of individuals as this makes ideas to be credible. This technique is used in "a board-certified cardiologist with own twenty-five years of experience" because by mentioning the experience and profession of Dr. William Leu the author refers to his prestige and this would make the audience believe the findings of this doctor.
On the other hand, the use of logos implies the author uses logic or facts to explain an idea. This can be seen in "patients who eat whole foods and a diet low in sodium are 75 percent less likely" because the author uses percentages, which are derived from the use of logic and mathematics, and refers to proven facts.

What is reproductive isolation?Why is it necessary for speciation to occur? Explain one way reproductive isolation might occur.
Answers
Reproductive isolation is a process in which individuals in a population are prevented from reproducing. This isolation can occur in several ways, such as a physical barrier that separated these species into two groups that will reproduce with each other and generate a new species.
Why is it necessary for speciation to occur?Speciation is an essential evolutionary process for the creation of new species. It is worth remembering that from reproductive isolation, the individuals of a population have been differentiating and evolving and in the end, there will be a different species from the initial one. Therefore, speciation is necessary for the emergence of new species.
Explain one way reproductive isolation might occur.Reproductive isolation may occur due to a geographic barrier. In this case, a population is separated by a geographic barrier such as a river, a canyon, or a mountain, thus generating subpopulations that will begin to evolve and adapt in different ways. In the end, we will have different subpopulations, but in the beginning, they were part of the same population.

What are transcription and tranlastion?
Transcription and translation are two processes involved in protein synthesis.
Transcription occurs first in the nucleus. During this event, mRNA is synthesized by copying a segment of the DNA molecule. The template DNA strand is used to pair its nucleotides and grow the new mRNA strand.
Translation occurs in the cytoplasm. During this event, the protein is grown by reading the mRNA codon sequence. tRNA, associated with rRNA, recognizes the codons and adds the correct amino acid to the new growing polypeptide.

well-differentiated csccs show horn pearls and single cell keratinization while poorly differentiated csccs have a lack of keratinization
Answers
Well-differentiated csccs (cutaneous squamous cell carcinomas) show horn pearls and single cell keratinization, while poorly differentiated csccs have a lack of keratinization.
Here's a step-by-step explanation:
1. Well-differentiated csccs: These are characterized by the presence of horn pearls and single cell keratinization.
- Horn pearls: These are small, round, keratin-filled structures that can be seen under a microscope. They are formed by the accumulation of keratinocytes, a type of skin cell.
- Single cell keratinization: This refers to the process in which individual keratinocytes in the tumor undergo keratinization, forming keratin-filled cells.
2. Poorly differentiated csccs: In contrast, these types of csccs lack keratinization.
- Lack of keratinization: This means that the tumor cells do not undergo the normal process of keratinization, resulting in a lack of keratin-filled cells.
In summary, well-differentiated csccs exhibit features such as horn pearls and single cell keratinization, while poorly differentiated csccs do not show keratinization.

unlike seedless vascular plants, seed plant reproduction does not require water and can happen in dry environments. the seed plant structure that allows for fertilization without water is
Answers
vascular plants, seed plant reproduction does not require water because, The seed plant structure that allows for fertilization without water is pollen.
The statement that best describes seed plant reproduction is that it does not require water and can occur in arid environments. This ability allows seed plants to colonize more areas than seedless vascular plants. Seed plants depend on pollinators such as insects, birds, and mammals to transfer pollen from the male reproductive organ to the female reproductive organ.
Pollen, which is carried by the wind, insects, and animals, fertilizes the female gamete and forms a zygote that develops into an embryo. The structure that allows for fertilization without water is the pollen. In seed plants, pollen grains are male gametophytes that have two sperm nuclei.
The pollen grain's tough outer covering enables it to resist desiccation and protects the sperm cells. The pollen grain is carried by the wind, insects, or other animals to the female reproductive organ's stigma, where it attaches and germinates.
The pollen tube grows from the pollen grain's tip, growing down through the style and into the ovule, where it releases the sperm nucleus, which then fertilizes the female gamete. Thus, pollen is a structure that enables seed plants to reproduce without requiring water.

Is overfishing density dependent or density independent?
Answers
Answer: Overfishing is density dependent.
Overfishing is density dependent because as the number of fish decreases, the negative effects of overfishing become stronger. When there are a lot of fish, they can reproduce and replenish their population. However, if too many fish are caught and the population becomes small, it becomes difficult for them to reproduce enough to sustain their numbers. This makes the impact of overfishing even more harmful and harder for the fish population to recover.
