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.
A cell has 6 chromosomes. How many chromosomes will each daughter cell have if it undergoes mitosis
Answer:
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

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.

↬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.

Which of the following is NOT a
piece of evidence that Darwin
used to support his theory of
evolution?
A. fossil record
B. similarities among different species
C. the amount of shared DNA between species
Fossil record is not a piece of evidence that Darwin used to support his theory of evolution.
What is the theory of evolution?Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits.
Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor.
The current evolutionary theories can be categorized as Darwinism and Lamarckism. Charles Darwin theorized Darwinism. He explained his theory of natural selection in his book, On the Origin of Species.

Oxygen atoms are different from the atoms of every other elements (true or false)
false I think, but I don't know for sure
Answer:
True
am not sure but my explanation:
An oxygen atom possesses 8 protons, 8 massive, positively charged nuclear particles. There are also 8 massive, neutrally charged nuclear particles, 8 neutrons in the common isotope, 16O. And orbiting the nuclear core, there are 8 electrons, fundamental particles with negligible mass that each possess a formal negative charge.
Any atom with 8 protons is automatically an oxygen atom by defintion. 7 protons specifies a nitrogen atom; 9 protons specifies a fluorine atom. Of course, oxygen generally takes the form of the dioxygen molecule, O2. The number of protons gives Z, the atomic number, which is different for each element.
