Assuming these are carbon dioxide molecules, which way do you think the molecules will move and why?

A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)

B. Into the cell. They want to move from low to high concentration (UP the concentration gradient).

Answers

Answer:

A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)

Explanation:

Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata (Figure 3b).

A. Out of the cell. They want to move from high to low concentration (DOWN the concentration gradient)

Using a specific example, predict and explain how the release of non-native organisms can affect local, national, and even global ecosystems.

Answers

A nonnative species may not have any natural predators when being introduced subsequently it won’t have any competition with the other organisms living in the same ecosystem. This will make the other organisms struggle for food and other resources and could potentially make them go extinct. They can also have drastic effects to the local biodiversity (for the previous reason). Also, due to the competition or newly introduced predator (assuming they’re a predator) the preexisting organisms of the ecosystem may start to relocate and start a new ecosystem or if there are neighbouring towns/cities may have to forage for food there - which would obviously be dangerous for both them and us. Hope these few examples help.

What type of mutation occurs when a nucleotide is added to the DNA?

Answers

Answer:

A frameshift mutation.

Explanation:

A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.

In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.

Julio is studying the evolutionary history of desert cottontail rabbits, sea otters, and grizzly bears. All three species share some body structures, but all three also have some differences in their body structures. Below is a table that includes some of the body structures Julio is studying. How could Julio explain why all three species share some body structures and have some differences? Why do only grizzly bears and sea otters have canine teeth?

Answers

Answer:

Explanation:

One way that Julio can explain such differences is that their environments are very similar and therefore the traits that were best suited for their survival were passed on from generation to generation. The traits that each species developed differently would have been due to their diet. Each species has a different diet and certain traits allow them to more easily hunt/gather the food that they need to survive. For example, grizzly bears and sea otters both eat fish as their main diet and therefore have both developed canine teeth, while rabbit teeth are different due to them only eating vegetation.

Which technological tool helps earth scientists gain new knowledge about earth’s subsurface?
Group of answer choices.

B. Digital balance

C. Ground penetrating radar

G. Hydrometer

Answers

Answer:

ground penetrating radar

Ground penetrating radar technological tool helps earth scientists gain new knowledge about earth’s subsurface. Thus the correct option is C.

What is Ground penetrating radar?

Ground penetrating radar detects non-metal and metal objects, as well as voids and underground irregularities. It makes possible to measure the depth, dimensions, thickness of targets. It provides data quickly and can cover a large site area.

Ground penetrating radar can go deep up to 100 feet (30 meters) in low conductivity materials such as dry sand or granite. Moist shale, clays, and other high conductivity materials, may attenuate or absorb GPR signals, greatly decreasing the depth of penetration to 3 feet (1 meter) or less.

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.
