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

Answers

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

Answers

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.

there are 3 types of mutations, base substitutions - single base mutations are called point mutations. Point mutations are the most common type of mutation and there are two other types. point mutations occur in DNA sequence seconding proteins are either silent, missense or nonsense. Deletions is the second type of mutation, this results when one or more base pairs are lost from the DNA. If one or two based are deleted the translation frame is altered resulting in a garbled message and nonfunctional product. A deletion of three or more bases leave the reading frame intact. A deletion of one or more corona result in a protein missing or more amino acids. this may be deletions or not. And lastly insertions this is when you have additional base pairs which may lead to frameshifts depending on whether or not multiples or three base pairs are inserted. combinations of insertions and deletions leading to a variety of outcomes are also possible.

4. What is the difference between genotype and phenotype? Write a 5 sentence
paragraph describing the difference between the two.

Answers

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
