In a lysogenic infection, the viral dna that is embbeded in a host cell's dna is called a(n)

Answers

Answer 1

Answer: The correct answer is prophage. In a lysogenic infection, the viral DNA that is embedded in a host cell's DNA is called a prophage. Prophage is actually a bacteriophage genome that is being inserted into the circular bacterial DNA chromosome.

What structures are lacking in the annelid's mouth that more advanced animals have?

Answers

Structures in the mouth region of the Annelids vary in a wider range. There are some annelids evolve jaws , which can be used in seizing their victims and preys, biting pieces of vegetation, or grasping decomposing matter. Even though some have evolved their jaws, majority of them are filter feeders. What lacks them that most advanced animals have? they dont have teeth.

Determine the amount of potential energy of a 5.0Kg book that is moved to three shelves on a bookcase. The height of each shelf is 1.0 meters, 1.5 meters, and 2.0 meters.

Answers

Answer:

The potential energy is 50 joules, 75 joules and 100 joules

Explanation:

Potential energy is the energy stored in an object by virtue of its position relative to others objects. For example a heavy ball placed at an elevated position.

The potential energy is given as:

$E_(p)=mgh$

Where $E_(p)$ is the potential energy of the object, m is the mass of the object, h is the height in which the object is placed and g is the acceleration due to gravity.

For 1.0 meters:

m = 5.0 kg g = 10 m/s² h = 1 meters

$E_(p)=mgh= 5.0*10*1=50$

The potential energy is 50 joules

For 1.5 meters:

m = 5.0 kg g = 10 m/s² h = 1.5 meters

$E_(p)=mgh= 5.0*10*1.5=75$

The potential energy is 75 joules

For 2.0 meters:

m = 5.0 kg g = 10 m/s² h = 2 meters

$E_(p)=mgh= 5.0*10*2=100$

The potential energy is 100 joules

What is the hydrologic cycle

Answers

The hydrologic cycle is the flow of water from the Earth's surface via evapotranspiration to the atmosphere, where it condenses, and back to Earth in the form of precipitation. This cycle is important to the circle of life.

The water cycle or hydrologic is a continuous cyclewhere water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. This repeats again and again in a never-ending cycle.

Which macromolecule forms a double layer as the primary structure of cell membranes?fatsoilsphospholipidssteroids

Answers

The correct answer is:

phospholipids

Phospholipids - they are made up of hydrophobic tails (inside the double layer) and hydrophilic heads (on the outside of the membrane).

Explanation:

Cell membranes comprise lipids (phospholipids and cholesterol), proteins and carbohydrates assemblies that are connected to some of the lipids and proteins.

Phospholipids are composed of a polar head and non-polar (hydrophobic) tail. They line up such that the heads and the tail groups are side by side to form a single layer due to the information between the head groups and the tail groups. Two of these layers line up with the hydrophobic tail groups facing each other to prevent the hydrophobic groups away from the polar cover collections of other phospholipids and from the water in the adjoining environment.
