Two examples of related organisms are dinosaurs/chickens, and the megalodon/the great white shark.
<h3>How have organisms evolved?</h3>
Life emerged on our planet 3.7 billion years ago, and since then organisms have evolved or changed over time this includes:
- The appearance of more complex organisms, which is the result of natural selection.
- The diversification of organisms.
- The extinction or disappearance of species.
This has caused all organisms that exist today to be related to other organisms of the past. Let's examine two examples.
<h3>Dinosaurs and chickens: </h3>
According to scientific research, birds evolved from dinosaurs. Indeed, it has been determined birds started with theropods, which were a specific group of dinosaurs.
This means modern birds including chickens are related to this group of dinosaurs, even if overtime birds have evolved a lot and they might not seem to be very similar to dinosaurs.
<h3>The megalodon and the great white shark:</h3>
These two species of shark likely share a common ancestor and due to this, both species have many similarities such as the shape of their teeth. However, megalodons are extinct, while great white sharks still exist today.

Answer:
Alfred Hershey and Martha Chase
Explanation:
In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.
Answer:Margulis
She is the one who discovered it
Answer:
Cellular structures means the organelles of the cell. Organelles are the parts of the cell which are responsible for their specific functions. Each organelle do some work for the cell. Some organelle produces proteins and energy i. e. ribosome and mitochondria respectively. Some are responsible for the removal of waste products such as lysosomes and vacuole. The function of cell is to produce energy from the food for the body.
The organelle in the table that correctly matches its function is the ribosome because it produces proteins.
<h3>What is a ribosome?</h3>
A ribosome is an organelle that functions as a protein factory in the cell, whereas vacuoles contain dissolved materials and store water.
Mitochondria are energy producers by the process of cellular respiration, and lysosomes contain hydrolytic enzymes.
In conclusion, the organelle is a ribosome that produces proteins.
