Why is a strong sense of taste so important for open ocean predators like oceanic whitetip sharks ?

2 answers:

Well, for one thing, to differentiate from plastic bags and garbage. This is especially true near the Great Pacific Garbage Patch.

Two, to track prey. Sharks can taste blood (or is it smell?) from far-off.

Answer:

The predators and prey both evolve simultaneously, maintaining a relationship with one another. Predators will die if they do not get food, so they are directly dependent on the preys. These prey also evolves over a due course of time in order to avoid being consumed by predators. The predators that exist in the ocean bodies being the topmost dominating organisms are considered as the open ocean predators. Some of its examples are Great White Shark, Orca, and oceanic whitetip sharks.

These organisms have the ability to smell thousands of times far better than humans. They can sense and detect objects that are located in distant places within the water body. These strong senses of taste are important for them in order to survive and consume their food.

Describe the genetic makeup of the offsprings of asexual reproduction.

WARRIOR [948]

Answer:

They are genetically identical to the parents and only differ if a genetic mutation occurs.

Sexual reproduction involves two parents and produces offspring that are genetically unique.

The greater the genetic variation, the better change that an individual in the population have a favorable gene that can help survival. Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.

All the cells in your body need ___________ to survive

Lesechka [4]

Answer:

Oxygen or Minerals or Sugars (Oxygen is the most relevant one)

Explanation:

To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.

How would being able to bring water into the gills when the mouth is closed benefit a bottom-dwelling shark or ray?

trapecia [35]

Answer:

The ability to bring water into the gills when the mouth is closed would benefit a bottom dwelling shark or ray, because it would allow them to be more discreet when in the process of catching prey and they would be able to stop swimming. Most sharks have to continuously swim or else they would sink, while being able to bring water into the gills when the mouth is closed would highly benefit them and allow them to stop swimming for a moment.

Explanation:

I am not 100% sure this is the correct answer, but I am currently doing a lab on this, so I am using the knowledge I previously had and online resources. I am pretty confident though.

In a sample of cells, the DNA content immediately following mitosis is measured and is equal to 10 picograms of DNA per nucleus.

Rasek [7]

Answer:

1. At the end of S phase- 20 pg DNA

2. At the end of G2 phase- 20 Pg DNA

Explanation:

The cell before undergoing M phase undergoes the steps of interphase that is G₁, S and G₂ phase.

During S phase, the process of cell replication takes place which replicates the DNA as a result of which the amount of DNA doubles. This DNA amount is reduced to half during the anaphase stage of M phase.

In the question since the amount of DNA is 10pg therefore the amount will be double during S phase and becomes 20 pg and will remain 20 pg until the DNA is distributed therefore at the end of G₂ phase Will remain the 20 pg.
