The southern oscillation refers to the difference in surface air pressure between _________

To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.

One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.

So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.

The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.

How is the process of photosynthesis taking place thru Calvin Cycle?

Juli2301 [7.4K]

This is the ideal question! Thanks for asking!

Before we start, let's go through a mini-review.

Photosynthesis:

The complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.

Calvin Cycle:

A series of biochemical reactions that take place in the stroma of chloroplast in photosynthetic organisms.

Now that we have gone through what these two terms are and their definitions, let's head onto the actual questions.

So the question asks, how is the process of photosynthesis taking place through Calvin Cycle?

In plants, carbon dioxide (CO2 $CO2$ CO2C, O, start subscript, 2, end subscript) enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions, where sugar is synthesized. Because they are not primarily fueled by light, these reactions are often known as the "light-independent reactions."

Carbon atoms from CO2 $CO2$ CO2 C, O, start subscript, 2, and end subscript are fixed (incorporated into organic molecules) and utilized to create three-carbon sugars in the Calvin cycle. ATP and NADPH produced by the light reactions are used to power and support this activity. Calvin cycle reactions occur in the stroma, as opposed to light reactions, which occur in the thylakoid membrane (the inner space of chloroplasts).

That's about it! If you'd like, check out the attachment for a visual!

Thank you,

The _______________ community has low diversity with microorganisms primarily in the Leptospirillum groups II and III and from t

ExtremeBDS [4]

Answer:

The <u>Acidophilic Microbial</u> Community has low diversity with microorganisms primarily in Leptospirillum groups II and III and from Ferroplasma types I and II.

Explanation:

An acidophilic microorganism or plant is one which grows best in acidic conditions.

They are also referred to as microorganisms which occur in acidic natural (solfataric fields, sulphuric pools) and man-made (eg. Acid mine drainage) environments.

Acidophilic Microbes otherwise known as Acidophiles are an ecologically and economically important group.

They possess networked cellular adaptations for regulating intracellular pH. Several extracellular enzymes from acidophilic microbes are known to be functional at much lower pH than that inside the cells.

Acid stable enzymes have applications in several industries such as starch, baking, fruit juice processing, animal feed and pharmaceuticals, and some of them have already been commercialized. Acidophiles are widely used in bio-leaching of metals from low grade ores

Recent studies show that acidophiles are currently being considered to be utilized in bio-conversion and bio-remediation, as well as in microbial fuel cells to generate electricity.

Acidophilic microbes of similar characteristics are classifed in groups for ease of study and identification.

Leptospirillum Group II and II as well as Ferroplasma types I and II are groups of acidophilic microorganisms within the Acidophillic Microbial community.

Cheers!
