Answer:

Methanotrophs.

Explanation:

Methanotrophs are those microbes (bacteria) which feeds on methane or used methane as energy source for their survival. These type of microbes survive by using single carbon compound as a source of energy. So we can say that due to the presence of Methanotrophs, the level of methane decreases while there is no change occurs in oxygen saturation level.

Why are matter cycles important in an ecosystem??ASAP!!!
Neko [114]

Answer:

Because the element carbon forms the backbone of the molecules that make up cells, one of the most important biogeochemical cycles to life on Earth is the carbon cycle. ... Carbon moves from living things back to the environment as all types of organisms use some of their food molecules as a source of energy.

Two organisms have analogous structures. A student concluded that these organisms must have a common ancestor is the student cor
arsen [322]

Answer:

The student is wrong, just because the analogous structures of any two organism may have the same structure or even have the some relation between there way of operation or functions.

Explanation:

  • <u>Analogous Structures:</u>

As the similarity between two or more different organisms structure or any organ does not means that they have same ancestors or have the common origin from which the evolve into two different species. Now analogous structures are very much similar in there structure physically, but two different organisms may use them for the same function, which is astonishing to see or observe in way different species.

  • <u>For example:</u>

As the structure of the flipper of a Dolphin has similarity with the phalanges of a human being and with the wings of the bat. As all of them functions for the basic need of movement or locomotion from one point to another. While, all the three species are very much different in there features and are not the same obviously.

Lynna [10]

Answer: 2.81 x 10∧14 baterias after 16 hours.

Explanation:

Hi, first we have to find how many 20 minute intervals are in 16 hours.

If 1 hour = 60 min, 16hours = 960 minutes (16 h x 60 min / 1 h)

If we divide the 960 minutes (16 hours) by 20 minutes we obtain 48. (960/48)

There are 48 twenty minutes intervals in 16 hours.

Now we have to apply the exponential growth formula:

P (t) = Po (1 +r) ∧t

Where:  

P (t) = population at time t  

P (0) = initial population (1)

r = growth rate (1)

t = time (48)

Replacing with the values given:

P (t) = 1 (1 + 1) ∧48= 2.81 x 10∧14

2.81 x 10∧14 baterias after 16 hours.
