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.

Answers

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.

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.
