Answer: located behing the trachea in the neck.

Explanation:

After chewing, the food bolus passes through the pharynx and is directed to the esophagus. There, peristaltic movements allow the cake to be directed to the stomach. The esophagus is a tube about 25cm long. Because of the friction of the bolus on its surface, it is lined with stratified epithelium. To lessen this friction, the epithelium is lubricated by mucus produced by the submucosa esophageal glands. Between the esophagus and the stomach is the gastroesophageal sphincter that prevents the reflux of gastric contents into the esophagus.

In plants tall (T) is dominant to short (t) and round seed is dominant to wrinkled seeds (r). If a parent is short and wrinkled

Nuetrik [128]

Answer:

Parent cross= ttrr (short, wrinkled) × TtRr (hybrid)

POSSIBLE GAMETES BY EACH PARENT:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

Explanation:

This question involves two genes in a certain plant. One gene is coding for height while the other is coding for seed shape. The alleles for tallness (T) and round seeds (R) is dominant over the alleles for shortness (t) and wrinkled seeds (r).

According to this question, a parent that is short and wrinkled (ttrr) is crossed with another parent that is hybrid (TtRr) for both traits. This means that the parent cross is as follows: ttrr × TtRr

The possible combination of gametes that will be produced by each parent is as follows:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

See attached image for the punnet square using these gametes.

How the cell cycle is abnormal in cancer?

Aleks [24]

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
