Con ayuda de un microscopio se observa una bacteria en el agua transcurridas (2) se miran muchas bacterias . Que ocurrio alli ,que tpo de reproducccion sucedio meiosis o mitosis
Answer:
Ninguna de las dos. No ocurre ni mitosis ni meiosis.
Probablemente haya ocurrido fisión binaria/bipartición.
Explanation:
En este caso estamos hablando de bacterias, organismos unicelulares procariotas. Estos tienen una forma de reproducción asexual denominado fisión binaria. Los eucariotas por su parte pasan por periodos de división celular implicada en el crecimiento denominado mitosis, y división celular implicada en reproducción sexual, denominada meiosis.
La fisión binaria, también conocida como bipartición, si bien muy parecida a la mitosis en algunos aspectos, es la forma de reproducción de las bacterias.
Ambas, mitosis y fisión binaria, implican un duplicado de material genético. El ADN se duplica y una copia va a cada célula hija. Lo mismo sucede con el resto del contenido celular. Finalmente ocurre citocinesis. Sin embargo, a diferencia de la bipartición, la mitosis requiere de mecanismos mucho mas complejos de duplicación celular e involucra también a la cariocinesis, ausente en bacterias.
La fisión binaria ocurre muy rápidamente, en un breve período de tiempo puede hallarse una diferencia considerable en la cantidad de células presentes en un sustrato, producto de esta división. Es por esto que el crecimiento que exhiben las bacterias como población, sigue un modelo exponencial.
Imagine a population of moths. White moths are easier for birds to see and eat. Black moths blend into their surroundings, so they are less visible to birds than white moths. As a result, black moths are more likely to survive and reproduce, enabling the gene for black coloration to be passed on to the next generation. This increases the frequency of genes for black coloration in the population. Which evolutionary process does this scenario describe
Answer:
The correct answer is - natural selection.
Explanation:
Natural selection is a process of adapting according to the environmental change in order to survive and reproduce and increase their number. It is represented by Darwin for the first time. Natural selection leads to evolution.
In this case, White moths adapt according to the environment by increasing the population of black moths in order to blend with the surrounding and as the result, black moths are more likely to produce and survive and passed this trait to the next generation.
El aparato digestivo de los cocodrilos, adaptado para ingerir una gran variedad de presas es una adaptación de tipo?
La respuesta correcta para esta pregunta abierta es la siguiente
A pesar de que no anexaste opciones o incisos para responder, podemos comentar lo siguiente.
El aparato digestivo de los cocodrilos, adaptado para ingerir una gran variedad de presas es una adaptación de tipo evolutivo morfológico.
Esto significa que a través de los años, la evolución de los cocodrilos los ha llevado a ajustar sus órganos, tal y como es el caso del aparato digestivo.
Esta capacidad de adaptación es una de las tantas maravillas de la naturaleza que permite la adaptación de los organismos de los animales a las necesidades que tienen y los hábitats donde viven, para que puedan sobrevivir cazando los tipos de animales que comen para poder sobrevivir en sus estados naturales.

Over the centuries cockroaches have become smaller and flatter, making it easier for them to hide and find their way into home cabinets and pantries. What does this demonstrate?
Geographic isolation plays a role in speciation
frem
The environment is important in selecting adaptations
Artificial selection can result in the development of resistant species
Selective breeding can result in passing favorable traits to the next generation
Answer:
adaptation
Explanation:
the roaches adapt to their small environment and get smaller due to evolution

Explain the role of aquaporins in the rapid movement of water through some cells
Answer:
In the early 1990s, aquaporins were discovered, and it was found that they can selectively control water movement into and out of cells. One of the critical functions of aquaporins is that while they allow the passage of water they prevent the passage of ions.

which of the following scientists can be identified as a taxonomist?
Answer: Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world. Using morphological, behavioral, genetic and biochemical observations, taxonomists identify, describe and arrange species into classifications, including those that are new to science.

What do you need to create a chemical bond?
Answer:
A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. The types of strong bond differ due to the difference in electronegativity of the constituent elements.

1.Consider the model above compare the DNA sequence of the model and abnormal CFTR gene explain the differences and similarities between the two.
2. Explain what caused the abnormal structure of CFTR protein.
3. Considering the structure of the mutant protein channel do you think it can perform the same function as a normal CFTR protein channel explain why or why not?
Answer:
1.Their similarities are that they both contain the codons for the following amino acids Isoleucine (ATC), glycine (GGT) and valine (GTT).
Their differences are:
a. Their codons for the second isoleucine molecule is different, ATC in the normalgene compared to ATTinnthe abnormal gene.
b. The codon for the amino acid phenylalanine is lacking in the abnormal gene.
2. The abnormal structure of the CFTR protein is because the amino acid phenylalanine is lacking in the polypeptide chain of the that region of the protein. This would result in an error in the secondary and tertiary structure of the protein.
3. The mutant protein would not be able to perform its function of channelling chloride ions across the membranes because the protein molecule is not properly folded for this function.
Explanation:
1. The DNA sequences of the normal CTFR gene and that of the abnormal CFTR gene shows some similarities as well as some differences.
Their similarities are that they both contain the codons for the following amino acids Isoleucine (ATC), glycine (GGT) and valine (GTT).
Their differences are:
a. Their codons for the second isoleucine molecule is different, ATC in the normalgene compared to ATTinnthe abnormal gene.
b. The codon for the amino acid phenylalanine is lacking in the abnormal gene.
2. The abnormal structure of the CFTR protein is because the amino acid phenylalanine is lacking in the polypeptide chain of the that region of the protein. This would result in an error in the secondary and tertiary structure of the protein.
3. The mutant protein would not be able to perform its function of channelling chloride ions across the membranes. This is because the protein molecule is not properly folded for this function. As illustrated by the model, while the normal protein can open for ions to move through, the mutant protein cannot.
4. Explain why the cave appears black.
Answer:
Caves normally apear black. Yes, this is because in a cave there are no natural sunlight or lights in a cave. For example, If your room was all dark it would look black...yes. Same with a cave! It will appear black as well. So, as you can see, Caves appear black because it is so very dark inside no lights nothing. So that is why it looks black.

Bacteria can reproduce by exchanging DNA. This exchange is called:
Binary Fission
Conjugation
Endospore production
Sexual reproduction
Answer:
conjugation
Explanation:
Bacteria reproduce by binary fission, resulting in two daughter cells identical to the parent cell. Bacteria can exchange DNA through the processes of conjugation, transformation, or transduction.
