Answer:
Neil Shubin bases his argument that the anatomy of Tiktaalik is relevant to that of humans by discussing specific features of the anatomy of Tiktaalik that vary from typical fish anatomy and correspond to features of the human body. For example, he points out that Tiktaalik has a neck that is able to bend independently of the rest of the body, unlike fish, and like all terrestrial vertebrates, including humans. Therefore, the evolutionary history of humans can be traced to an organism similar to Tiktaalik, resulting in the concept of the "inner fish."

What happens to a species when the environment undergoes a radical change (e.g. due to climate, food source) and the organisms do not adapt? Explain your answer in not less than 3 sentences. May cite a hypothetical; situation to explain the answer.
Answer:
If an environment rapidly changes and an organism cannot adapt it will mostly die out. For example, some birds have long, thin beaks that let them reach insects inside trees. If these insects were to disappear for some reason and seeds became the main food source then the birds with long, thin beaks would not be able to eat. Other birds with different adaptations, like short, strong beaks, would be properly adapted to this new environment. So, this second species would replace the first species.

d. Freezes and then vaporizes
We can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.
Why did the water vaporize and then condense?As the water was heated by the electric heater, its internal temperature increased. Once this temperature reached the boiling point of water, the water vaporized or evaporated into a gas. This gas then reached the mirror, where it collected and cooled down, condensing back into a liquid in the form of water droplets.
Therefore, we can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.

A vaccine is a substance that contains all or part of a noninfectious version of a disease-causing organism. When the vaccine is administered to a person, the person's immune system attacks the noninfectious version of the organism and learns to recognize its surface proteins. The next time the immune system comes in contact with the same surface proteins, it has a defense already prepared in order to respond quickly to the invading organism. In this way, a vaccine gives people immunity to the disease-causing organism.
Vaccines can be life-saving, but there have been a few cases of people catching a disease from the administered vaccine.
How might genetically engineered organisms solve this problem?

how does the enzyme present in the globular myosin head play its role during muscle contraction
In addition to binding actin, the myosin heads bind and hydrolyze ATP, which provides the energy to drive filament sliding. This translation of chemical energy to movement is mediated by changes in the shape of myosin resulting from ATP binding.
A student conducted a controlled experiment to test the affects of tea tree oil on the growth of Trichophyton rubrum, the primary cause of athlete's foot. He inoculated 10 test tubes of broth with the fungus and then added 1 mL of a tea tree oil solution to each.

A.
results that are similar but with slightly different data.
B.
entirely different results with no obvious pattern.
C.
the exact same data in every circumstance.
D.
entirely different results with the opposite pattern to the first.
If the results from the controlled experiment to test the effects of tea tree oil on the growth of Trichophyton rubrum are valid, a similar experiment should produce results that are similar but slightly different data.
What is reproducibility?In science, valid results from experiments must be reproducible.
In other words, the same experiment carried out by different researchers must produce similar results with very little to no variation.
If results from an experiment are not reproducible, such results cannot be valid as far as science is concerned.

Off the Monterey Bay coast in California there is a kelp forest. The kelp grows talls and sways in a sea full of sunshine. It
provides a protective habitat for many maturing species. The kelp is consumed by sea urchins which are consumed by sea otters. Over fishing in the ocean reduced the food for killer whales so they came close to the coast to prey on the sea otters. The drop in sea otters caused a rise in sea urchins which greatly reduced the kelp.
In this ecosystem, the _______

is a keystone species.

What property of water describes the molecule as acting like a tiny magnet?
Answer:
Intermolecular forces
Water is a dipole and acts like a magnet, with the oxygen end having a negative charge and the hydrogen end has a positive charge. These charged ends can attract other water molecules.
The entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom. Thus a polarity develops in each O−H bond, and therefore, the water molecules are polar in nature and act like little magnets.
