<h2>Answer:</h2>

The statement given in option C is not the function of stomach.

<h2>The stomach has 3 primary functions: </h2>

Transitory holding for nourishment, which goes from the throat to the stomach where it is held for 2 hours or more.
Blending and breakdown of nourishment by compression and unwinding of the muscle layers in the stomach.
Absorption of nourishment

The mucosa contains specific cells and organs that produce hydrochloric acid and stomach related chemicals to help digest nourishment. The mucosa in the cardiovascular and pyloric layer of the stomach discharge bodily fluid that shields the coating of the stomach from the acid delivered for processing.

Answer:

Explanation:

Before food gets to the stomach, it is first masticated in the mouth then after swallowing, pass through the esophagus before entering the stomach. The stomach then physical churns foods that help in digestion and also produces digestive enzymes like pepsin. Stomach has folds called ruggae that increase surface area for which food is broken down by enzymes. In addition the stomach lining producs HCl that creates an acidic environment to kill bacteria. Food stays in the stomach for about 4 hours before moving on to the ileum.

These changes are likely genetic mutations

<h2>Further Explanation </h2>

Evolution is the process of change in all life forms from one generation to the next, and evolutionary biology studies how this evolution takes place. Every generation of organisms inherits traits owned by their parents through genes. <u><em>Changes (called mutations)</em></u> in this gene will produce new traits in the offspring of an organism. In an organism's population, some traits will become more common, while others will disappear. traits that help the survival and reproduction of organisms will be more likely to accumulate in a population than unfavorable traits. This process is called natural selection. The income of more offspring than the number of parents along with the inheritance of these traits is an additional fact about life that supports the scientific basis of natural selection. In a long time, this isolated population will become a new species.

_____________________, commonly known as sea squirts, have a larval stage that resembles a chordate.

Urochordates, commonly known as sea squirts have a larval stage that resembles a chordate.

What are Urochordates? Give the characteristics of it.

Ascidians (sea squirts) are a common term for the Urochordata, also known as the Tunicata. The body of an adult tunicate is fairly simple. While possessing all the characteristics of a chordate, including a notochord, a dorsal nerve cord, pharyngeal slits, and the larva of many tunicates swims freely and lacks only these characteristics. Ascidia, Salpa, and Doliolum, for instance.

Characteristics features of Urochordata:

1. The grownups are anchored to the foundation.

2. It is also known as "Tunicate" because an adult's body is covered by a tunic formed of tunicin, a cellulose-like substance.

3. The notochord only appears in the larval stage and vanishes in the adult.

4. In adults, a dorsal ganglion takes the role of the nerve cord that is present in the larva.

5. The larva can migrate and changes into a different animal.

Identify the phase of mitosis for each plant cell diagram shown below.

madreJ [45]

Answer:

1. Metaphase

2. Prophase

3. Telophase

4, 5, 6, 8. Interphase

7. Anaphase

Explanation:

Mitosis is a cell division involving the formation of two genetically daughter cells. The process of mitosis involves stages including: interphase, prophase, metaphase, anaphase and telophase.

Interphase is the resting stage of the cell. It is th stage where the cell prepares for the division. Numbers 4, 5, 6, and 8 in the image are stages of interphase.

Prophase is the stage where the chromosomes become visible and arrange in pairs. Number 2 in the image depicts a plant cell in prophase stage.

Metaphase is the stage where the chromosomes align at the equator/middle of the cell. This alignment orients the chromosomes for separation. Image 1 depicts this metaphase stage.

Anaphase stage is the stage where the chromosomes separate into opposite poles of the cell. Image 7 depicts the anaphase stage of this plant cell.

In the Telophase stage, the cell plate forms to divide the plant cell into two. This is shown in image 3.
