3 examples from finding nemo of organisms that use camouflage as an adaptation to survive

Answers

The Flounder (Mr. Johansen in Finding Nemo), uses coloration technique as camouflage by imitating or blending in the colors and textures of the ocean floors. The Puffer Fish (Bloat). Aside from being able to make itself appear big to drive away the predators, it can also blend in the ocean floors and rocks similar of its color. Regal Tang (Dory) uses camouflage as well. This kind of fish is known for its bright and vivid colors, but when it senses harm, it can make itself somewhat see-through and easily blends with the colors of its surroundings. 

Three adaptations of Nemo fish include:

  • coloration
  • rounded caudal fins
  • high velocity when swimming

What is an adaptation?

Adaptation is a phenotypic and/or physical feature that confers an evolutionary advantage to the individual.

  • An adaptation may confer a different evolutionary fitness according to the environment.

In conclusion, three adaptations of Nemo fish include coloration, rounded caudal fins and high velocity when swimming.

a human skin cell contains 46 chromosomes. A frog sprem cell conrains 12 chromosomes. which paie of number of a normal gamete from each of these species

Answers

Human 23, frog 12
Because gametes contain half the number of usual chromosomes, so a human gamete would have 46/2 or 23 chromosomes. A frog sperm cell is a gamete so it would have 12 chromosomes anyway.

The __________ molecule is known as the universal energy source of the cell.

Answers

The comment is correct, it is ATP, Adenosine Triphosphate which in turn breaks down into ADP or Adenosine Diphosphate. They recur in a cycle of forming one or the other, when ATP breaks down into ADP, energy is released. 

Why are individual chromosomes more difficult to see during interphase than during mitosis?

Answers

In the interphase, they are really thin, just one strand which is only a few atoms wide (very challenging for an optical microscope and not too easy for the electronic one)

Answer:

This

Explanation:

Individual chromosomes are more difficult to see during interphase because they are not tightly coiled and condensed. During mitosis they are tightly coiled, making them easier to see. ... In anaphase I of mitosis, sister chromatids separate.

Which of the following statement is true of a semi-conservative model of replication?1) Each newly synthesized double helix of DNA contains one new strand and one old strand.

2)DNA synthesis involves conserving only part of each of the original strands in a DNA molecule.

3)The original DNA molecule is stored in the cell nucleus and serves as a template for creating copies containing two new strands.

4)DNA synthesis involves conserving one strand of a double helix of DNA and discarding the other.

Answers

Answer - A
Semi-conservative model of replication involves the replication of DNA in all the familiar cells in such a way that each newly synthesized daughter cell contains a double helix with one new strand and one old strand.

The statement that is true of a semi-conservative model of replication is "each newly synthesized double helix of DNA contains one new strand and one old strand. The correct statement is A. 

How is the DNA code itself a homology?

Answers

Answer:

Explanation:

These fundamental similarities are most easily explained by evolutionary theory: life shares a common ancestor. ... In fact, the DNA code itself is a homology that links all life on Earth to a common ancestor. DNA and RNA possess a simple four-base code that provides the recipe for all living things.

Answer:

the DNA code itself is a homology that links all life on Earth to a common ancestor. DNA and RNA possess a simple four-base code that provides the recipe for all living things.
