describe how the results of the hershey-chase experiment would have been different if proteins were the genetic material

1 answer:

4 0

The results would have found that it was radioactive Sulfur that was passed from other generations in the infection rather than the radioactive phosphorous discovered in the DNA. But Hershey and Chase concluded that DNA, not protein, was the genetic material.

If we compare the genetic codes of the four organisms seen here, which statement is MOST accurate?

bezimeni [28]

<h3>Answer;</h3>

All four organisms have exactly the same components in their DNA, but it varies in number and sequence

<h3>Explanation;</h3>

DNA, known as deoxyribonucleic acid is a type of nucleic acid which is important to all living organisms as it helps store genetic information.
All living organisms store their genetic information using DNA molecules or RNA molecules. Most organisms contains DNA that have similar components, however their DNA will differ in number and also the sequences.
The similarity between the molecules of DNA indicates a common ancestry among organisms.

Adapt extinct mutation

lisabon 2012 [21]

That organism will survive in the future which adapt themselves according to the environment.

<h3>What is fitness?</h3>

Fittest is the term describes living things that are best suited to their environment.

Species that survive are the ones that adapt, make or meet changes.

Florida has a rich fossil record spanning from the Eocene to recent times. Florida fossils are often very well preserved.

Two examples of land animal fossils found in Florida are the giant sloth and the saber-tooth tiger.

Some animals unable to adapt to the changing environment became extinct .

Living things mutate over time to meet their changing environment.

This biologist, Darwin, studied evolution in the 1800s.

The glyptodont was a giant, armadillo-like animal with a spiked tail that once lived in Florida.

The Origin of Species is a book written in 1859 about natural selection.

Nature selects the fittest for survival because they have useful traits.

Changes may occur in animals due to changes in the sequence of base pairs in their DNA, and this is known as a mutation.

Oldfield mice show variation in the color of their fur.

The survival of the light-colored old field mice on Florida's Gulf Coast is an example of the process called adaptation.

Evolution is a controversial theory that has survived much criticism.

Which two natural resources will be most affected as people try to meet the growing demand for food

Fudgin [204]

Land and water are the two natural resources will be most affected as people try to meet the growing demand for food.

Meeting the growing demand for food will involve planting more food crops and this will requires more lands. The planted crops will also need water in order to grow very well. Thus, more land and water will be needed to produce more food.

The wood in a match is made of cellulose, a polymer of glucose molecules. when you light the match heat and light are given off,

slavikrds [6]

The wood in a matchstick is made of cellulose, a polymer of glucose molecules. When you light the matchstick, heat and light are given off, indicating that an exothermic reaction is occurring.

There are two types of reactions:

1. Exothermic reactions: In these reactions, the reactants combine to form product and heat is liberated. Example, burning of fuel.

2.Endothermic reactions: In these reactions, the reactants combine to form product and heat gets absorbed from the surroundings. Example, photosynthesis in plants where the energy of the Sun gets absorbed.

PLS HURRY What type of work uses ATP to pump substances across membranes?

lyudmila [28]

I would say the answer is transport work!

Substances can go through the cell membrane through active and passive transport! Active transport is powered by adenosine triphosphate, ATP!
