There are several mechanisms through which reproductive isolation occurs. Which situation is an example of behavioral isolation?


A.

Mules, the offspring of a male donkey and a female horse, are unable to reproduce because they are sterile.

B.

Males of different, closely related species of fireflies signal for mates by flashing different light sequences.

C.

The reproductive organs of snails only properly align when the male and female belong to the same species.

D.

Red and purple sea urchins cannot reproduce with one another because the sperm and egg cannot fuse.

Answer:

D.  decomposers

Explanation:

primary, secondary consumers and producers all eventually die.  Decomposers break the  dead organisms down to nitrogen, carbon and other basic elements that can then be used as nutrients for the new plants.

Answer:

1. The Los Angeles flood of 1938 was one of the largest floods in the history of Los Angeles, Orange, and Riverside Counties in southern California.

2. The flood was caused by two Pacific storms that swept across the Los Angeles Basin in February-March 1938 and generated almost one year's worth of precipitation in just a few days.

3. The Los Angeles, San Gabriel, and Santa Ana Rivers burst their banks, inundating much of the coastal plain, the San Fernando and San Gabriel Valleys, and the Inland Empire.

4. Flood control structures spared parts of Los Angeles County from destruction, while Orange and Riverside Counties experienced more damage.

5. It caused $78 million of damage ($1.42 billion in 2019 dollars),[2] making it one of the costliest natural disasters in Los Angeles' history.[3] In response to the floods, the U.S. Army Corps of Engineers and other agencies began to channelize local streams in concrete, and built many new flood control dams and debris basins

nuevas tecnologías y desarrollos científicos muchas veces conllevan un potencial para generar daños irreversibles sobre las poblaciones humanas y el medio ambiente

Explanation:

Los avances científicos y tecnológicos conllevan grandes ventajas para la humanidad y simultáneamente también riegos que pueden producir daños irreparables en las sociedades y el medio que las rodea. Por ejemplo, el dominio de la tecnología basada en el uso de la fisión nuclear ha sido beneficioso para obtener grandes cantidades de energía, pero también este desarrollo conlleva la producción de armamento nuclear que pone en riesgo a las sociedades y al medio ambiente. Otro ejemplo puede estar representado por el uso de la tecnología de edición genómica CRISPR-Cas, la cual ha sido recientemente desarrollada. Esta tecnología ha llevado esperanza para el tratamiento de enfermedades genéticas hereditarias a través de la restauración de la función génica. Sin embargo, la técnica CRISPR-Cas de edición genómica ha sido recientemente utilizada para desarrollar bebés editados genéticamente, aún cuando los efectos secundarios que dicha tecnología no han sido completamente resueltos (efectos de edición genómica en regiones genómicas no deseadas), con lo cual llevando un serio riesgo para los bebés que han sido modificados genéticamente. De este modo, cada avance científico tecnológico debe estar apropiadamente regulado por las sociedades a fin de evitar los potenciales efectos dañinos de dichos avances.

Answer: Geysers are water that comes out of the ground spurting into the air, wetlands are self-explanatory, while volcanoes are full of magma, not of acid and limestone.The upper layers of soil above the groundwater contains carbon and limestone. The water being combined with carbon becomes acidic which erodes limestone this results in formation of sinkholes and caves.

Answer:

Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Explanation:

Please mark me as brainlist

Photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.

Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.

It can also be defined as a method used by plants and other living things to change light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.

Through photosynthesis, plants transport carbon from the atmosphere into the biosphere and up the food chain. They use solar energy to chemically combine carbon dioxide, oxygen, and hydrogen from water to create sugar molecules.

Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time.

Thus, photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.

C) phenotypic plasticity

Explanation:

Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.

Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.

These bacteria are notoriously adaptable and might be found in many different environments (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.  

They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine.

Answer:

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Explanation: (credit to Chris Hall in Quora)

On the geological scale, the equation for photosynthesis would be the opposite of combustion/respiration: carbon dioxide and water molecules converted into oxygen and carbohydrate (or hydrocarbon) molecules (one unit of -CH2O- per CO2).

However, such a simplistic formula is extremely misleading, especially when talking about individual plants and algae instead of macro-geo-chemistry. The oxidation of water to oxygen (aka the light reactions) is a separate (but concurrent) process from the reduction of carbon dioxide to carbohydrate or hydrocarbon (aka the dark reactions). See my answer to a similar question here: Chris Hall's answer to Where is the most detailed chemical structure breakdown of all steps of photosynthesis that is reliable?

Some bacteria, algae, and plant cells only perform one half of the typical photosynthetic pathway, either to produce energy without making sugar/hydrocarbon or to assimilate carbon dioxide using stored chemical energy rather than using light directly (similar to chemosynthesis). And some bacteria do photosynthesis without making oxygen at all, using sulfur in the place of oxygen.

In short, photosynthesis should be thought-of as a series of sequential processes and not as a single chemical reaction.

Answer: D) North Korea

==============================================================

Explanation:

The United States, the United Kingdom, and France are all countries that have capitalistic economies. This means that (for the most part) private industry and the market determines what products are produced and who gets those products. I said "for the most part" because these countries don't follow a purely capitalistic structure. There are some elements of government regulation to ensure that no breakdowns occur. The regulations are also to ensure some level of fairness as well, in addition to preventing things like fraud.

On the other hand, countries like North Korea are known as command economies because the government determines what products are to be made and they determine who gets the products. This means that they set the prices as well to whatever they feel is correct (even if the market may disagree otherwise). The term "communism" is often strongly connected to the term "command economy".
