Answer: The correct answer is- Muscular foot and unsegmented soft body.

Mollusk is the second most diversified phylum ( the first being arthropoda) of animals. Organisms under this phylum are predominantly found in the marine habitats.

The name “mollusca” corresponds to the soft body of the organism ( as the earlieast mollusk is cuttlefish, which is an unshelled organism).

Muscular foot is the locomotory organ of this phylum, which can be contracted and retracted whenever required.

Organisms belonging to this phylum share certain characteristics, including a muscular foot, a visceral mass having internal organs, and a mantle, which may or may not secrete calcareous shell ( that is made up of calcium carbonate).

Major organs involved in the digestive system include the mouth, stomach, small intestine, large ... When it reaches your stomach, a sphincter opens and dumps the food in. ... To move into the small intestine, chyme must pass through the pyloric sphincter. From here it enters the duodenum, the first part of the small intestine.

The inner mitochondrial membrane contains numerous inward folds called cristae, which greatly increase the surface area of this
erastova [34]

Answer:the villi of the intestine

Explanation:like the cristae of the mitochondria which increase the surface area for the production of ATP,the villi of the intestine acts similarly.

In animals, digested food pass from the stomach to the intestine. In the intestine , enzymes acts on the food. Absorption of food takes place there and there are some structures that facilitates it. The walls of the intestine have numerous foldings , alongside the presence of finger like projection called villi. Microvilli are also presence from the cell walls of the intestine . These projections increase the surface area for the absorbing of food .they brush against food in the intestine and promotes absorption of nutrients.

If you count 52 purple rough corn kernels and 50 yellow smooth corn kernels how many people smooth corn kernels should you expec
Vitek1552 [10]

Answer:

17

Explanation:

In corn,

Smooth kernel (S) is dominant to rough kernel (s)

Purple kernel (P) is dominant to yellow kernel (p)

Since no information has been given about the cross here let us assume it to be a standard dihybrid cross.

The phenotypic ratio of dihybrid cross is 9:3:3:1. 9/16 will show dominant phenotype for both traits, 3/16 will show dominant phenotype for one trait, other 3/16 will show dominant phenotype for the second trait, 1/16 will have recessive phenotype for both the traits.

Here,

Purple rough (P_ss) = 52

Yellow smooth (ppS_) = 50

Both of them show dominant phenotype for one trait so they each form 3/16 of the progeny.

If the total progeny was z, 3/16*z = 50

z = (50*16)/3 = 267

Total progeny = 267 kernels

Yellow rough kernels (ppss) = (1/16*267) = 17

So approximately 17 corn kernels will be yellow and rough.
