I disagree with the above answer. The answer should be D as the different nucleotide sequences would result in different proteins formed and synthesized that would eventually perform different functions and account the for the structural differences between the two species. While amount of DNA differ, it does not account for the vast differences observed.

How do eukaryotic plant and animal cells differ from one another?
Ber [7]

Answer:

The eukaryotic plant animal cells are differ having some cell organelles in it.

Explanation:

The first difference is the cell wall, which is present in all eukaryotic plants. It gives shape and rigidity to the plants. But all the animal cell the outer covering is cell membrane. They lack cell wall.

All the plant cell have chlorophyll pigment. It helps them to photosynthesis. In animal cell, chlorophyll molecule are absent. So they depend on plants for their food.

The eukaryotic plant cell more space is occupied by the vacuoles. It stores food and water for the plants. However, animal cells have no vacuole or if present, it is very small in size.

All animal cells have lysosomes, which help in digestion of various materials in the cell. Plants does not contain lysosomes.

Besides this organelles all other structure of plant and animals are similar. They both have nucleus, DNA, cytoplasm, mitochondria, etc.

1. <span>what is the amount of the bolus dose, in both milligrams and milliliters, that you will administer in the first minute? 
</span>The doses is 0.9 mg/kg and the weight of the patient is 143 pounds. So, the total doses of drug needed will be: 
Total doses= 0.9 mg/kg * 143 pounds * 0.453592 kg/pound= 58.37 mg.

10% of the doses will be given bolus for 1 min, so the amount would be:
Bolus doses= 10%*58.37 mg= 5.837 mg.
In mililiters, it would be: 5.837 mg * 1ml/mg= 5.837 ml.

<span>2. what is the amount of the remaining dose that you will need to administer?
The remaining dose would be 90% of the total dose. You can either calculate it directly or subtract the bolus doses from the total doses.
Remaining doses= total doses- bolus doses= </span>58.37 mg- 5.837 mg= <span>52.533mg</span>

Sound waves travel through gas liquid and solids A) True B) False
Novay_Z [31]

Answer:

True.

Explanation:

  • Sound is a form of Energy that produces a sensation of hearing in our ears.
  • Sound is produced as a result of vibration produced in a body.
  • Sound energy is transmitted from one place o other place by wave motion.
  • When a body vibrates, the particles of medium surrounding it starts vibrating about their mean position.
  • During vibration, they collide with the surrounding particle and transfer some energy to them.
  • They then start vibrating faster and transferring  energy to the next surrounding particle. This process continues till the vibration reaches a person ear.
  • Thus, particles are an important factor in propagation of sound.
  • Sound cannot travel in vacuum.
  • It requires a medium to travel from one point to another.
  • A sound can travel in all medium, solids, liquids and gases as all of these have particles.
  • The speed of sound is highest in solids and lowest in gases as the inter molecular space is largest in gases and smallest  in solids.
