Answer:
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.
Write down the word and chemical equition of photosynthesis process
Answers
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.

Which nation would be CLOSEST to the command side on this economic
continuum?
O the United States
O the United Kingdom
O France
O North Korea
Answers
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".

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.
Answers
Answer: B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.
Reproductive isolation refers to the inability of the members of a species to breed with members of other species. Behavioral isolation is a type of reproductive isolation, in which mating between the members of the species is facilitated by their behavior. It helps members of the same species to identity their mates. It prevents mating between population of distinct species.
Males of different, closely related species of fireflies signal for mates by flashing different light sequences is an example of behavioral isolation because flashing of light by fireflies is the behavioral characteristic which shows their desire for mating. The mates identify the light signals flashed by their partner belonging to the same species.
Answer:
B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.

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.

What best describes the role of photosynthesis and respiration in the carbon cycle?
Answers
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.
What is photosynthesis?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.

A kid on a trampoline has 1,000 J of potential energy when they are at the top of a jump. How much kinetic energy will the kid have when they come halfway down?
A. 100 J
B. 250 J
C. 500 J
D. 1000 J
Answers
Answer:
C. 500 J
Explanation:
Given;
potential energy of the kids at the top of the trampoline, P.E = 1,000 J
⇒At the top of the trampoline, the kids have only potential energy.
⇒On half way down, the kids have both kinetic energy and potential energy.
⇒At the bottom of the trampoline, the kids have only kinetic energy.
Based on the statements above, the kinetic energy of the kids half way down is calculate as;
P.E + K.E = 1000 J
Base on law of conservation of energy, P.E = K.E
2 K.E = 1000 J
K.E = ¹/₂ x 1000 J
K.E = 500 J.

Measuring Cellular Respiration
A student wanted to compare germinating pea seeds (growing) and nongerminating pea seeds
(not growing). She wanted to test two variables: germinating vs nongerminating peas at two
different temperatures: 10° C and 25° C.
The student proceeded to set up two electronic water baths: a warm water bath (25° C) and a
cold water bath (10°C). She also set up four respirometers: two containing germinating peas
and two containing non-germinating peas. Where would she need to place the respirometers in
terms of water baths to ensure that she was setting up a controlled experiment?

Answers
Answer:
Follows are the solution the given choices:
Explanation:
The four approaches represent are arranged as follows:
Two approaches represent must be positioned in the [tex]10^0 \ C[/tex] water bath. Another respirometer to pea seeds so one respirometer to pea seeds without germinating.
She must put 2 breath meters at the [tex]25^0 \ C[/tex] water bath. Yet another respirometer to pea seeds or one respirometer to pea seeds without germinating.
The regulation would be carried out after germinating as well as nongerminating pea seed to bathometer in [tex]10^0 \ C[/tex] water bath.
