Answer:

The suitable words for fill in the blanks will be -

  1. embryo
  2. flippers
  3. disappear
  4. off
  5. genetic

Explanation:

Examining a dolphin embryo highlights its evolutionary history. Early in dolphin development, both fore and hind limb buds form. While the forelimb buds continue to develop into flippers, the hind limb buds disappear. The genes that are normally active in the hind limb buds of four-limbed animals are turned off. A genetic change leading to the silencing of a trait during development may have been an important milestone in cetacean evolution.

Which type of cell contains DNA enclosed in a nucleus?
goblinko [34]

The answer is  :

B. A eukaryotic cell's nucleus contains the DNA or the genetic material of the cell.

The DNA  has the necessary information for the cell's construction and the control of the synthesis tasks done by the cell. The nucleus is protected by the nuclear membrane. It surrounds the nucleus with a membrane with many pores.

Explanation:

The nucleus is a membrane-enclosed organelle located in most eukaryotic cells. The nucleus is the largest organelle in the cell and includes most of the cell's genetic information (mitochondria also contain DNA, called mitochondrial DNA, but it proceeds up just a small portion of the cell's overall DNA content. Inside its fully enclosed nuclear membrane, it contains the preponderance of the cell's hereditary material. This material is designed as DNA molecules, along with a family of proteins, to form chromosomes.

What proteins are crucial for creating and maintaining dna replication forks?
Lubov Fominskaja [6]
Proteins (Polypeptides with a unique amino acid sequence) are required to guarantee that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction Helicases unwind the two strands of parental DNA and creates the replication fork; single strands binding proteins keep the single strands from reuniting

Why is frog egg laid in long gelatin fluid
Naya [18.7K]
Although amphibious frogs live on land and in water, they must lay their eggs in water or the eggs will dry up, effectively killing the offspring inside. Frog eggs are covered with a glycoprotein, which helps keep the eggs moist. This glycoprotein has to keep in contact with a source of moisture, such as water.
