Can you explain how more life forms were able to be created because of cyanobacteria

Biology

patriot [66]4 years ago
8 0

Cyanobacteria play an important role in the biosphere by converting atmospheric nitrogen into mineral nitrogen directly assimilated by other organisms. This capacity is of fundamental importance in coral reefs where nutrients are scarce.

Moreover, Cyanobacteria are the micro-organisms of choice for humans in various branches of biotechnology because of the many families of molecules that they produce and which have an interest in valorization.

Which of these processes as a cooling affect on earth? (APEX)
scoundrel [369]

Answer:

The answer is A. Evaporation of water due to warmer temperature causes low thick clouds.

Explanation:

Evaporation is the process in which liquid is changed into gas due to increases temperature or pressure. It is an important part of water recycling in nature. water from sea, rivers and streams evaporate and form clouds which brings water back to earth by raining. Evaporation also causes cooling effect as during evaporation heat is absorbed from the environment. On the other hand the cloud formation and rain also induce cooling by bringing down the temperature.

PLEASE HELP! ASAP! FIFTEEN POINTS!
oee [108]

Answer:

Anatomy supports the theory of evolution because some species share similar physical features that was present in a common ancestor.

An example of shared anatomy is sharks and dolphins. types of analogous structures, such as dolphins and sharks, do not prove species are related, but rather they support the Theory of Evolution by show how species do build up adaptations in order to fit into their environments

Molecular biology because DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

in recent research is has been shown that the myoglobin and hemoglobin sequences for dozens of mammals, birds, reptiles, amphibians, fish, worms, and molluscs were related.

Structural similarities is when different animals share the same structural similarities. For example the skeletons of turtles, horses, humans, birds, and bats are very similar, despite their t different ways of life and the diversity of their environments.

How is glucose different from glycogen?
Zigmanuir [339]

Glucose is different from glycogen as Glucose is used immediately for energy in the cell while glycogen is stored in the liver for later use as energy. Thus, the correct option is A.

<h3>What is Glycogen?</h3>

Glycogen may be defined as the reserved form of glucose that is constructed up of many interconnected glucose molecules.

When the cell needs immediate energy to accomplish metabolism, they directly use glucose for it, but while energy is not needed by the cell, then glucose is stored in the liver and muscles in the form of glycogen.

Therefore, Glucose is different from glycogen as Glucose is used immediately for energy in the cell while glycogen is stored in the liver for later use as energy. Thus, the correct option is A.

On a certain day, Donnie observes the wind is blowing at 2 miles per hour. A bird nesting near Donnie's house flies three quarte
kipiarov [429]

Answer:

Air speed of bird is 4.17 mph

Explanation:

let the speed of the bird in still air be "X"

Speed of the bird when it flies in the direction of flow of wind = X+2

Speed of the bird when it flies in the opposite direction of flow of wind = X-2

The total time taken is equal to 12 minutes

= \frac{12}{60} \\= \frac{1}{5} hours

The distance in miles is equal to \frac{3}{4} = 0.75 miles

  \frac{0.75}{X+2} + \frac{0.75}{X-2} = \frac{1}{5}

On solving the above equation, we get -

2 X = (X^2 -4)*\frac{1}{0.75 *5} \\X^2 -4 -0.75 X =0\\X = 4.17

Air speed of bird is 4.17 mph

the grand canyon was carved, separating what had once been a single population of squirrel into two seperate populations. what d
tatiyna

Answer:

They became different.

Explanation:

Since the populations were separated and were not able to interact, they could not reproduce. Eventually, mutations would work their ways into each of the separate populations of squirrels. Since the two populations can't mix their genes through breeding they will slowly start to get different. For example, one population could experience a mutation that changes the color of one animals in the one of the populations. This squirrel will spread its genes to its offspring and if it is a good trait then it will spread throughout the population. The other population will not experience a widespread invasion of this trait because the two populations can't breed.
