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.

Which of the following examples is NOT classified as composite volcano?

Answers

Answer:

C. Mt. Maton

Explanation:

not sure but hope it helps

Mt. Mayon examples is NOT classified as composite volcano.

What is Composite volcano?

Cone-shaped composite volcanoes, also known as stratovolcanoes, are formed from numerous layers of lava, pumice, ash, and tephra. Composite volcanoes typically generate tall peaks rather than rounded cones because they are composed of layers of viscous material rather than fluid lava.

Calderas are occasionally created when the peak crater collapses. The most destructive volcanic eruptions in recorded history have been caused by composite volcanoes.

Apart from Earth, Mars is the only known location in the solar system with stratovolcanoes.

Therefore, Mt. Mayon examples is NOT classified as composite volcano.

The principal enzyme involved in DNA replication is called _____________. The enzyme joins ________________ to synthesize a new _______________ strand of DNA. DNA replication is called ______________ because each new DNA molecule is made up of one original and one new strand.



complementary

DNA polymerase

nucleotides

semiconservative

Answers

Answer:

The principal enzyme involved in DNA replication is called _DNA polymerase_. The enzyme joins _nucleotides_ to synthesize a new __complementary_ strand of DNA. DNA replication is called __semiconservative__ because each new DNA molecule is made up of one original and one new strand.

Explanation:

DNA replication is the process through which DNI molecule duplicates. This event takes place during the S stage of the interphase. So when the cell divides during mitosis or meiosis, each cell will get a complete set of chromosomes.

DNI replication is semi-conservative because each new molecule carries an original DNI strand and a new one. The fact that the new molecule is composed of an original strand makes it semi-conservative. The old existing strands are used to synthesize the new complementary strand.

The origin of the replication requires helicase enzymes to break hydrogen bonds and separate the two original strands. The topoisomerase enzyme is necessary to release tension. Other proteins are also needed to join the strains and keep them separated. Once the molecule is opened, there is a region named replication forks. DNA polymerase makes the new nucleotides enter into the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs timine, and cytosine pairs guanine.

DNA strands are antiparallel, and replication occurs only in 5´-3´direction. So one of the strands will replicate continuously, while the other strain will be formed by short fragments known as Okazaki fragments.

Primers are needed to make the DNA polymerase work. Primers are small units of RNA and are placed at the beginning of each new fragment.

Possible variations of a gene that controls a specific trait

A) Heredity

B) Phenotype

C) Gene

D) Allele

Answers

Answer:

D

Explanation:

Alleles are the different possibilities for the trait (brown, blue, green.)

Possible variations of a gene that controls a specific trait are referred to as alleles. Therefore, the correct option is D.

Alleles are different types or forms of a gene that reside at the same locus on a certain chromosome. They contribute to the wide variety of traits seen within populations and can exist in several forms, such as dominant or recessive.

For example, there may be alleles for blue eyes, brown eyes, or green eyes, for a gene that affects eye color. Different alleles play a role in the variety of phenotypes (observable characteristics) that people can display.

Therefore, the correct option is D.

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.

What is an adaptation? Give an example of one.

Answers

Answer:

Adaptations are special skills that help animals survive in their environments. For example, in order for pelicans to catch their prey, they use their pouch-like beaks to scoop up fish. This is an example of physical adaptation; the animal is using its body parts to help it survive.

Explanation:

My answer is self-explanatory; this is not plagiarized.

It is the action of adapting to something. For example, if a wild fire wides out 40 acres of forest then all the animals that lived there would have to find somewhere else to live and adapt to their new environment.
