¿En que proceso de reproducción bacteriana no se produce la recombinación?
Answer:
Puesto que las bacterias "hijas" son geneticamente idénticas a la célula madre, la fisión binaria no da oportunidad a la recombinación o diversidad genética (más allá de la mutación aleatoria ocasional). Esto contrasta con la reproducción sexual.

The models below represent nuclear reactions. The atoms on the left of the equal sign are present before the reaction, and the atoms on the right of the equal sign are produced after the reaction. Model 1: Atom 1 + Atom 2 = Atom 3 + energy Model 2: Atom 4 = Atom 5 + Atom 6 + energy Which of these statements is most likely correct about the two models? Both models show reactions which produce energy in the sun. Both models show reactions which use up energy in the sun. Model 1 shows reactions in the nuclear power plants and Model 2 shows reactions in the sun. Model 1 shows reactions in the sun and Model 2 shows reactions in a nuclear power plant.
Answer:There are two kind of nuclear ractions: fusion and fission reactions.
Both release a huge amount of energy in different ways.
Fusion reactions are nuclear reations in which two smaller (lighter) atoms combine into a larger (heavier) atom, with the respective release of energy.
That is what model 1 shows:
Model 1: Atom 1 + Atom 2 = Atom 3 + energy
That is the process that happens and is responsible for the huge amount of heat produced in and released by the Sun.
In the Sun two atoms of hydrogen fuse into a larger atom of helium.
That is represented by the nuclear reaction:

O Cells in mitosis and meiosis go through the PMAT stages once to produce diploid cells.
Answer: Cells in mitosis go through the PMAT stages once to produce diploid cells while cells in meiosis go through PMAT stages twice to produce haploid cells. (3rd option)
Explanation:
Cells in mitosis go through the PMAT stages once to produce diploid cells while cells in meiosis go through PMAT stages twice to produce haploid cells.
Mitosis is a process by which a single cell divides to produce two daughter cells. In diploid (2n) organisms, somatic cells contain two copies of each homologous chromosome, thereby mitosis will produce two identical diploid cells. Mitosis consists of four phases: Prophase, Metaphase, Anaphase and Telophase.Meiosis is a process by which a single cell divides twice in order to produce four cells with half the original amount of chromosomes, it is for that reason that meiosis is recognized as a reductional division. Meiosis is divided into meiosis I and meiosis II. The phases of meiosis I include Interphase I, Prophase I, Metaphase I, Anaphase I, Telophase I, and cytokinesis; whereas the phases of meiosis II include Interphase II, Prophase II, Metaphase II, and Telophase II, and cytokinesis.During meiosis I, the chromosome or chromosomes duplicate their genetic information (S phase of the interphase I) and subsequently homologous chromosomes exchange genetic material during prophase I. In diploid organisms, these two daughter cells generated by meiosis I divide again in meiosis II in order to form haploid (n) gametes.Learn more in:

D. Oxygen
Answer:
A.) Carbon Dioxide
Explanation:
The main purpose of cellular respiration is to produce ATP. However, one of the byproducts is carbon dioxide. We use the process of cellular respiration when we take in oxygen (so oxygen isn't the answer) and breathe out CO2. Cellular respiration takes place in the mitochondria, but that's not what's released.

What would happen to the owl population if the population of bats decreased?
Answer:
In an ecosystem if one thing goes wrong then all organisms will fall apart , so if the whole race of owls were to die then the food chain and life cycle wouldn't be able to work properly
hope it helped!
If the population of bats decreased, it could potentially have a negative impact on the owl population as owls rely on bats as a significant food source.
Owls are known to be efficient nocturnal predators, and their diet often consists of small mammals, including bats. Bats serve as a primary food source for many owl species, especially those that are specialized in hunting at night. Therefore, a decrease in the population of bats could have consequences for the owl population.
If the bat population decreased, it would likely result in a reduced availability of bats as prey for owls. This could lead to a decline in the food supply for owls, potentially resulting in reduced reproductive success, decreased survival rates, and overall population decline.
Owls have evolved to be specialized predators, and their diet may be heavily dependent on certain prey species, such as bats. The removal or reduction of a significant food source can disrupt the balance of their ecosystem and have cascading effects on the owl population.
However, it's important to note that the impact on the owl population may also depend on various factors, including the availability of alternative prey species and the adaptability of owls to find alternative food sources. Some owl species have more flexible diets and can switch to other prey items if their primary food source becomes scarce. Additionally, the overall ecological context and interactions with other species would also play a role in determining the exact outcome for the owl population.
In summary, a decrease in the bat population could potentially have negative consequences for the owl population as it would likely result in a reduced food supply. However, the exact impact would depend on various ecological factors and the ability of owls to adapt to changes in their prey availability.

Que semejanzas y diferencias tiene el microscopio y el de Robert hooke
Answer:
- Microscopio de Robert Hooke: Aumento de 30X; monocular; con soporte rudimentario; enfoque de objetos transparentes y opacos
- Microscopio óptico actual: más sofisticado, binocular; compuesto por tres sistemas: sistema mecánico, sistema óptico (hasta 1.500 aumentos 1500 X), y sistema de iluminación.
Explanation:
El microscopio óptico fue el primer microscopio y marcó una nueva era en la biología y la medicina, siendo fundamental para la observación de estructuras celulares y subcelulares, lo cual permitió el desarrollo de diversas teorías tales como, por ejemplo, la teoría celular. La característica más importante compartida por los microscopios ópticos es el uso de la luz visible para visualizar las muestras. Los microscopios ópticos rudimentarios fueron popularizados en el siglo XVII, a partir del uso de Galileo Galilei. Posteriormente, en 1665, el científico inglés Robert Hooke usó su microscopio mejorado para observar muestras biológicas. El microscopio de Hooke era monocular y aumentaba la imagen 30 veces (30X), tenía un mejor soporte que los microscopios anteriores más rudimentarios, y podía enfocar tanto objetos transparentes como opacos. Actualmente, los microscopios ópticos están compuestos por tres sistemas: 1-sistema mecánico compuesto por piezas (es decir, una base, platina y brazo) donde están insertadas las lentes, un 2-sistema óptico compuesto por diferentes lentes conocidas como lentes oculares (microscopios binoculares) y lentes objetivos, las cuales permiten el aumento de las imágenes hasta 1.500 (1500X, con uso de aceite de inmersión), y 3-un sistema de iluminación para reflejar, transmitir y regular la intensidad de la luz.

Explanation:
Non-native species like kudzu, zebra mussels, and nutria experience _____ outside their native area due to a lack of natural predators and their ability to compete more successfully than native species for resources.
Answer:
exponential growth
Explanation:
The organisms that are not native of a particular environment but are exposed to live in that particular environment are invasive species. Usually invasive species do not prove useful to the new area and prove harmful to the environment as well. There are some species of organisms that have been accidently introduced to new environment and have been accidently proven to be beneficial. Zebra mussels, being the native to Black Sea when arrived to North America flourished there.
