an example of...

A)growth and response

B)genotype mutation

C)phenotypic plasticity

D)inclusive fitness

Answers

Answer:

C) phenotypic plasticity

Explanation:

The ability of an organism to change phenotypically according to environmental conditions is known as Phenotypic plasticity.

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.

Sulfur-reduction bacteria are obligated anaerobic microorganisms, that are metabolically versatile. They might grow either as heterotrophs using organic molecules or as autotrophs using hydrogen and carbon dioxide.    

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.

 

is chemical reaction between limestone and acid in groundwater responsible for its formation

Answers

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.

Explanation:

that is an example of a point mutation. A point mutation is a mutation  that causes only one nucleotide to change and in the example adenine changes to thymine

hope this helps (:

The mutation shown here is point mutation.

What is mutation?"A changes/alteration in nitrogenous bases sequence of DNA that can results in changes in the genotype and phenotype of an organism is known as mutation."It occurs due to: deletion, insertion, translocation and inversion.During insertion, an extra nitrogenous bases are added to the DNA sequence.During deletion, a nitrogenous bases are removed from the DNA sequence.During inversion, the sequence of nitrogenous bases gets inverted in a DNA strand.In translocation, a sequence of one DNA strand breaks off and attaches to another DNA strand.What is point mutation?"A point mutation occurs in a genome when a single base pair is added, deleted or changed."

Here, the sequence of original strand is A T A C A C and the sequence of mutant one's is T T A C A C. The base A is changed into base T.

Hence, the correct option is: D. Point mutation.

5 facts about the L.A. flood of 1938
I will give you all my points!

Answers

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

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.

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.

A car turns left while maintaining a speed of 20 m/s. Does the car’s velocity change? Explain your reasoning!

Answers

Answer:

Yes

Explanation:

Speed is a scalar quantity (only has a magnitude). It signifies the rate of change of an object's movement.

Velocity is a vector quantity that signifies the rate of change of movement but also the direction of an object's movement.

Since the car turns, its direction changes, so the velocity changes.

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".

If Individual 3 has children with a woman that is heterozygous for the genetic disorder, what is the probability they will have an affected child?

Answers

Well let’s draw a punnet square. So first make your four boxes. Now, heterozygous means having two different alleles of a particular gene. We’re going to use the letter ‘A’, but you can use any letter. In your first box there will be the dominant alleles. This can be identified as ‘AA’. A dominant allele is capitalized (A). A recessive allele is lower case (a). So in the first box it will be AA. Move over to the box on the right it will be Aa. Move down one box (on the right side) that will be aa. Now still on the bottom box, move over one to the left. That will be Aa. Since hetero means different, the heterozygous alleles would be Aa which means you have 2/4 probability of the child being affected. So 1/2.

If Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

What is the genetic disorder?

A recessive genetic disorder, such as cystic fibrosis, and an autosomal dominant disorder, such as Huntington's disease, are examples of genetic disorders caused by a gene that can express itself in either a dominant or recessive manner. For example, the disease is represented by the aa. If the male is heterozygous for diseases such as "Aa," then he will produce 25% "aa" type offspring when he crosses with the heterozygous female. When a man is purebred AA and crosses with a heterozygous female, then no offspring will be genetically infected.

Hence, if Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

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


A.

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.
