5 0

Answer:

Rugae

Explanation:

These are the inner folds of the stomach. The folds are pronounced in an empty stomach that is not yet distended by food. They also increase the surface area in which the food is in contact with digestive enzymes produced by the stomach walls.

What are some outcomes of nuclear fusion?
Svetlanka [38]

Answer:

A. produce larger materials from the collision of smaller materials

Explanation:

The outcome of nuclear fusion reaction is that it produces larger materials from the collision of smaller materials.

  • Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
  • The energy released provides the needed temperature for another set  of atoms to fuse.
  • This process in turn yields a bulkier material accompanied with the release of a lot of energy.

What genes direct the
Valentin [98]

Answer:

a. hox genes.

Explanation:

HOX genes have the following functions:

  • HOX genes are the homeobox subset.
  • They specify the areas of the embryo's body plan along the animal head-tail axis.
  • They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.
  • They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.

The vertebrates are highly preserved.

The clusters and other genes occur uninterrupted.

Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.

The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.

Answer:

Letter a) Protists would have less permeable membranes than those in hypotonic or Isotonic environments, wlowing less water to enter the coll. Also, they could possibly develop higher salt concentration within the cell to retain water.

why is important to use an organism with a recessive phenotype in a cross with an organism of unknown Genotype
bogdanovich [222]

Answer:

One of the central conclusions Mendel reached after studying and breeding multiple generations of pea plants was the idea that "[you cannot] draw from the external resemblances [any] conclusions as to [the plants'] internal nature." Today, scientists use the word "phenotype" to refer to what Mendel termed an organism's "external resemblance," and the word "genotype" to refer to what Mendel termed an organism's "internal nature." Thus, to restate Mendel's conclusion in modern terms, an organism's genotype cannot be inferred by simply observing its phenotype. Indeed, Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations. Mendel thus wondered how organisms preserved the "elementen" (or hereditary material) associated with these traits in the intervening generation, when the traits were hidden from view.
