The space shuttle is the transportation device used to travel from earth to space.It is used to transport people to orbiting spacecraft. 3×10⁸ is the mass of the space shuttle.

<h3>What is space shuttle?</h3>

The space shuttle is the transportation device used to travel from earth to space. it is a type partially reusable rocket-launched vehicle to go into orbit around Earth.

It is used to transport people to orbiting spacecraft.

As we know the mass of the Earth is 5.972 × 1021 kg so that the earth's mass and the mass of the shuttle must be more than the figure .The total must be more than the mass of the earth.

But the total value is less. Hence the given mass is the mass of space shuttle.

To learn more about the space shuttle refer to the link;

Evolution creates not the best solution but the most available. Building on your answer to the previous question what does this
Greeley [361]

This statement means that evolution has happened by getting the genes of the  right trait expressed at the right time to help adaptability.

Explanation:

Evolution is a result of natural selection which emphasize on the survival of the fittest. But the occurrence of this trait has been possible with genetic variation. It means that if the genes for the particular feature is not present in the genome how would it occur and adapt to the environment. Thus, evolution promotes the most available option for the adaptation and hence for natural selection.

We can conclude that all features are not adaptable some are the results of genetic drift or mutations.

In case of cheetah,  the faster running genes would have been there they got expressed over the period of time for better adaptability.

Ipatiy [6.2K]

Answer:

I haven't really learned about cell types but I did find this information

Explanation:

How can epinephrine have different effects on different cells? Different cells have different receptors that bind epinephrine. Different cells activate different enzymes as a result of epinephrine binding.

epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction. Other significant effects include increased heart rate, myocardial contractility, and renin release

Hope it at least helps a little :)

In winter, although many parts of Europe have heavy snow falls, the sea ports remain ice-free and ships come and go. What could
son4ous [18]

The answer is (A. A warm current flows along the coast.) Currents carry cold and warm water from place to place. It's an amazing phenomenon that scientists are still trying to fully figure out.  Some think it's caused by wind, others think it's caused by the shifting of the tectonic plates, but one thing's for sure, currents are VITAL for this planets life.
