Put the following layers of the digestive tract wall in order from the lumen to the deepest layer: 1. lamina propria 4. digestive (mucous) epithelium 2. muscularis externa 5. serosa 3. submucosa 6. muscularis mucosae
Answer:
4. digestive (mucous) epithelium
1. lamina propria
6. muscularis mucosae
3. submucosa
2. muscularis externa
5. serosa
Explanation:
The first layer of the digestive tract, starting from the lumen, is the epithelium. This has different characteristics depending on the digestive tract section. Then there is a loose connective tissue called lamina propria. Next, there is a layer of muscle called muscularis mucosae. It is only present in the digestive mucosae. The next layer is the submucosa, which has dense connective tissue and the submucosal plexus. Then it follows the muscular externa, which has muscle, and it is in all the digestive tract except for the esophagus and stomach. Lastly, we have the serosa layer.

Discuss 3 different types of mutations that can happen
Answer:
Explanation:
Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.

What does every living thing have to have? *
Chloroplast
Nucleus
DNA
Answer:
DNA
Explanation:
Answer:
Explanation:
Los cloroplastos son los orgánulos celulares que en los organismos eucariotas fotosintetizadores se van ocupando de la fotosíntesis. Están limitados por una envoltura formada por las dos membranas concéntricas y contienen muchas vesículas, los tilacoides, donde se encuentran organizados los pigmentos y demás moléculas que convierten la energía lumínica en energía química, como la clorofila.
El término cloroplastos sirve alternativamente para designar a cualquier plasto dedicado a la fotosíntesis, o específicamente a los plastos verdes propios de las algas verdes y las plantas. Aunque el reciente descubrimiento adiciona a más individuos en la lista, como lo es en el caso de Elysia chlorotica, que al digerir al alga Vaucheria litorea, adquiere los cloroplastos a sus tejidos, y gracias a esto, puede realizar la fotosíntesis.
¿De qué maneras son los espermatozoides diferentes a todas las otras células del cuerpo masculino?
Answer:
Los gametocitos masculinos, o espermatozoides, difieren de las células del cuerpo porque pueden entrar en meiosis y crear espermatozoides. En el ciclo de meiosis I, un espermatocito primario diploide ubicado en los túbulos seminiferosos de los testículos se divide en dos espermatocitos secundarios haploides. Las dos células se convierten en cuatro espermatozoides a través de la meiosis II.

3. What is the definition of recessive and dominant?
4. What is the difference between genotype and phenotype? Write a 5 sentence
paragraph describing the difference between the two.
Answer:
Recessive: relating to or denoting heritable characteristics controlled by genes which are expressed in offspring only when inherited from both parents.
Dominant: Refers to a trait that appears more frequently than another trait, resulting from interactions between gene alleles.
Explanation:
Genotype and phenotype differences
Genotype Phenotype
The hereditary information of the organism in the form of gene in the DNA and remains the same throughout the life. The characters of an organism which are visible are known as phenotypes.
Same genotype produces same phenotype. Same phenotype may or may not belong to same genotype.
Present inside the body as genetic material. Expression of genes as the external appearence.
The genotype is inherited from the parent to the offspring. The phenotype is not inherited from the parent.
It can be determined by scientific methods such as the polymerase chain reaction. It can be determined by observing the organism.
It is affected by genes. It is affected by genotype and environmental conditions.
For eg., Blood group, eye colour, height, genetic diseases. For eg., Weight, physique, beak of birds
