Answer:

The pygmy shrew

Explanation:

The pygmy shrew, which weighs in at less than an ounce, has the fastest heartbeat of any mammal at 1,200 beats per minute, according to the National Wildlife Federation.

I believe that would be the Hummingbird. Their hearts can be as fast as 1260 beats per minute. This is typically attained while they are hovering.

When they are just flying, their heart beats approximately 800 beats per minute.

When they are perched on a branch, it drops to around 400 beats per minute.

A lot of people wonder how a Hummingbird can make it through the night without eating, and that's a very good question. They normally have to eat every 15 minutes during the day, and they use their vision to find food including bugs that they snatch right out of the air.

Each night they go into a type of semi-hibernation called Torpor. Their energy consumption drops almost 90%, and their heart beats as low as 40 beats per minute. While they are in this state they are very vulnerable to predators such as tree snakes or anything else that can get to them. It takes them about 30 minutes to reverse this process so they can fly off in the morning and start the eating process all over.

How does an indicator differentiate between an acid and base?
Svet_ta [14]

Answer:

that is all I know sorry hope that may help you :)

Explanation:

Indicator is a substance which shows different colors in acidic and basic medium. Indicators can be natural (derived from natural sources) or artificial ( man-made) for example :

*Litmus is an indicator. Acid turns blue litmus into red while base turns red litmus into blue

* Turmeric solution does not show change in color (remains yellow) in acidic solution and turns red in basic solution.

Consider a 100-gram sample of radioactive cobalt-60.
svetlana [45]

It will take 5.2 years to decay.

The half life of cobalt-60 is 5.2 years. The half life is the time taken for the mass of the substance to decrease by a half.

here, the amount of remaining substance is 50%,

so, (\frac{1}{2} )^{n} = 0.5

n. log (0.5) = log (0.5)

n = 1

So it would take 1 half lives to decay this much, which is 1 x 5.2 which is 5.2 years.

what do you mean by radioactive decay ?

The process through which an unstable atomic nucleus loses energy via radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A material that has unstable nuclei is considered as radioactive.
