Answer:

t describes Linus Pauling's contribution to the understanding of DNA structure?

Having first discovered the spiral shape of proteins, Linus Pauling used x-ray technology to hypothesize that the DNA molecule consisted of two consistently spaced strands that formed a spiral shape.

Linus Pauling studied DNA base pairing.

Having originally studied proteins, Pauling proposed that DNA was a three-chained helix with a sugar-phosphate backbone at the center and bases sticking out from the backbone.

Linus Pauling conducted experiments to prove that DNA carried genetic information.

Explain the relationship among
Iteru [2.4K]

Answer:

There is an important relationship among  homeostasis, defective mitochondria, and the  symptoms caused by LHON.

Explanation:

There is a great relationship among  homeostasis, defective mitochondria and the  symptoms caused by LHON because defective mitochondria disturbs the homeostasis in the body. If mitochondria works properly, homeostasis will be maintained whereas if there is any defect occurs in the mitochondria then the whole homeostasis will be adversely affected because mitochondria is the powerhouse of the cell responsible for the production of energy for the cell. Symptoms occurs due to Leber's hereditary optic neuropathy (LHON) also effected the state of equilibrium in the body.

Assignment: 01.03 Transformation of Energy
trasher [3.6K]

The energy transformations that occur in the given devices are as follows:

  • Windmill - mechanical energy to electrical energy
  • Flashlight - electrical energy to light energy
  • Microwave - electrical energy to heat energy
  • Firecracker - chemical energy to heat, light, and sound energy
  • Bicycle - Chemical energy to mechanical energy
  • Battery - chemical energy to electrical energy

<h3>What is energy transformation?</h3>

Energy transformation refers to the processes by which one form of energy is transformed into another form.

The law of conservation of energy guides the various energy transformations that occur in the universe.

The law of conservation of energy states that energy is neither created nor destroyed but can be transformed from one form to another.

The energy transformations that occur in the given device are as follows:

  • Windmill - mechanical energy to electrical energy
  • Flashlight - electrical energy to light energy
  • Microwave - electrical energy to heat energy
  • Firecracker - chemical energy to heat, light, and sound energy
  • Bicycle - Chemical energy to mechanical energy
  • Battery - chemical energy to electrical energy

In conclusion, energy transformations occur according to the law of conservation of energy.

Flatworms use a system of canals and tubes with the ______ as their excretory organ.
Kazeer [188]
<span>Flatworms use a system of canals and tubes with the mouth as their excretory organ. They belong to the Phylum Platyheminthes. </span><span>Flatworms can be cut in half creating two individuals by binary fission. Binary fission is a type of asexual reproduction in which the offspring has the same features and characteristics of the parent. During binary fission, the DNA replicates into two and goes at the end of each membrane. And then the cell membrane divides into two daughter cells. Then cytokinesis follow.</span>

The data indicate the populations of mammals in the Florida Everglades in different years over the past two decades. The Burmese
Oduvanchick [21]

Answer:

The correct hypothesis would be - C) Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.

Explanation:

Burmese pythons are the invasive species in this new region as they originally found in South Africa, and also one of the largest snakes so they lack natural predators in this new setting or region.

These snakes depend on both types of food which means they are omnivorous and eat both herbivore and carnivores prey.

Thus, the correct answer is - Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.
