Answer:
35. A. homologous structure
36. B. analogous structure
37. B. analogous structure
38. C. vestigial structure
39. B. analogous structure
Explanation:
A homologous structure is a similar structure/trait found in different species because they diverged (evolved) from a common ancestor, i.e., these species share a common ancestor that had the homologous structure/trait. A homologous structure may have the same or different functions in the descendants. Conversely, an analogous structure is a similar structure/trait that evolved independently (i.e., by convergent evolution) in different species to have the same function, thereby these species don't share a common ancestor with the trait. Finally, a vestigial structure is a rudimentary biological structure found in an organism that has lost its original/ancestral function (e.g., the appendix in humans or the hindlimbs of the snake). Vestigial structures provide strong evidence for evolution by use/disuse of body parts.
Homologous and Analogous structures differentiate in origin and function. Vestigial structures have lost their function. A) Homologous, B) analogous, C) analogous, D) vestigial, E) analogous.
What is an homologous structure?Homologous characters are the structures of different organisms that,
are composed of the same basic elements. share the same position in the body and the same relationship with adjacent structures.share the same embryological development.These structures might express some variations between the organisms that might be related to their function and to the environment. Their function is not necessarily the same in all the organisms involved.
These homologous characters are present in organisms related that share a common ancestor.
What is an analogous structure?Analogous structures are those body parts of different organisms that accomplish the same function, but they are originated from different areas. These structures do not share the same origin.
What is a vestigial structure?Vestigial structures are those body parts, genetically determined, that have been retained during the evolution of the taxonomic group but have lost or reduced their original function.
Such vestigial structures were plenty functional in the ancestors of new species, but now are typically degenerate, stunted, or rudimentary, and tend to be much more variable than homologous non-vestigial parts.

↬Define a Cell in Biology.
The cell is the basic structural, functional, and biological unit of all living organisms.
The structural and essential component of life is the cell. Cell biology is the study of cells, including their fundamental makeup and the purposes of each of their organelles.
The first biologist to discover cells was Robert Hooke. Cells make up every living thing. They could consist of several cells (multicellular) or just one cell (unicellular) (multicellular).
The tiniest cells known to science are mycoplasmas. All living things are constructed from cells. They give the body structure and turn the nutrients from the diet into energy.
Complex cells conduct a variety of tasks for an organism's parts. They resemble masonry bricks in that they come in a variety of sizes and forms.

Innate immunity ________. is found only in vertebrates is the first, and most general, mechanism of protection against pathogens depends on an infected animal's previous exposure to a pathogen is based on recognition of antigens that are specific to a pathogen
Answer:
is the first, and most general, mechanism of protection against pathogens
Explanation:
Innate or natural immunity is one of the two types of immunity an organism can possess (the other being; acquired immunity). Innate immunity is the FIRST defensive response of an organism against pathogenic attacks. The acquired immune system is only activated when the innate immune system has been penetrated or surmounted.
For example, the skin, mucus secretion, inflammation etc. are all natural or innate defenses against foreign invaders. Therefore, according to this question, innate immunity the first, and most general i.e. commonly used, mechanism of protection against pathogens.
Organ transplantation, stem cell research, and cloning, are all examples of biotechnology.

Answer:
I don't know your reasons on how you would feel about becoming an astrobiologist but this is what I found and my feelings.
Explanation:
The Perseverance twin is called Optimism. This has all of the same electronics as Perseverance and it’s important to have a twin so that they can test things before they operate Perseverance. When they do land on Mars they need the twin to test out all of the sequences and plan that they have for the rover before they send them up to Perseverance on the surface of Mars. Also, if they have a problem with Perseverance it gives them a place to practice how they recover from that problem.
Personally, for me, I would not like to become an astrobiologist. I like science but not that much. I like the simple questions of why and how does it work. I’m not entirely sure that we as humans are meant to be on any other planet except earth. Earth has been here for many many years and seems to reset itself. I don’t care why and will never know why in my lifetime. I’s just not something that I like to considerate doing as a career.
NASA is targeting no earlier than April 8 for the Ingenuity Mars Helicopter to make the first attempt at powered, controlled flight of an aircraft on another planet. Before the 4-pound (1.8-kilogram) rotorcraft can attempt its first flight, however, both it and its team must meet a series of daunting milestones.
Ingenuity remains attached to the belly of NASA’s Perseverance rover, which touched down on Mars Feb. 18. On March 21, the rover deployed the guitar case-shaped graphite composite debris shield that protected Ingenuity during landing. Ingenuity is battery powered and completely sef recharging from the solar panel on the top. The rover currently is in transit to the “airfield” where Ingenuity will attempt to fly. Once deployed, Ingenuity will have 30 Martian days, or sols, (31 Earth days) to conduct its test flight campaign. All data and pictures will be transmitted to Perseverance and then uploaded for all to see.

PLEASE HELP!!!! You are a scientist tasked with writing a journal article on the evolution of alligators. In 3–5 sentences, describe the different forms of evidence you might use to analyze the evolution of alligators.
Answer:
The first alligator ancestors evolved about 245 million years ago.
Explanation:
The first alligator ancestors evolved about 245 million years ago due to change in the environmental condition. crocodilians appeared about 80 million years ago during the Cretaceous period. Modern alligators has experience less changes which is closely related to their ancient ancestors and look much like to their relatives that exists about 80 million years ago. The main reason for the change in the body structure of alligator is due to change in environmental condition.
The evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.
What is evolution?Evolution means descendence with some class of modification in offspring (phenotypic, genetic, etc).
Evolution can be analyzed by sequencing and comparing the linear order of nucleotide sequences between different species.In conclusion, the evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.
