What property of water created the evolutionary pressure allowing it to glide seamlessly through the water?

Viscocity

200

Where is the oldest University in Europe?

A. London

B. France 

C. Italy

C. Italy

The University of Bologna, founded in 1088 in Italy, is considered the oldest university in Europe and the world. It was the first institution to use the term "universitas" for the corporations of students and masters, marking the birth of the modern university system. It remains an important academic institution and continues to operate today.

A man cuts a hole in the ice and begins fishing through the hole. If the air temperature is below freezing, which property of water allows its temperature to remain stable. 

Specific Heat Capacity

A scuba diver spends 8 hours in the ocean and later gets sick, begins shivering, and suffers from hypothermia. This is due to what physical property of water

Thermal conductivity - water is very good at transferring heat from your body to the water.

Below is the quaternary stucture of a low density lipoprotein. A lipoprotein carries cholesterol in the body. Please explain the aspects of a lipoprotein that allow it to carry cholesterol (fat) in the blood which is water. Talk nerdy

Remember the M&M model

Hydrophilic outer protein coating

Squishy hydrophobic fatty center.

Describe a drop of water going from the soil to a leaf, hundreds of feet up in the air. Be as specific as possible. Use correct terminology. Talk nerdy

Stomata opens.

Water transpires 

Hydrogen bonding creates cohesion pulling water up through the Xylem.

Cohesion is aided by they hydrogen bonding of water molecules to the side of the xylem.

Transcription occurs at the Nucleus with mRNA copying complementary codes

300

What type of reaction builds nucleotides (Anabolism)? What type breaks it down (Catabolism)?

Building = Condensation 

Breaking = Hydrolysis

400

Pepsinogen is a protein enzyme produced by the stomach to break down or HYDROLYZE proteins. It consists of 386 amino acids. How many nitrogenous bases in your DNA are needed to code for this enzyme?

1 Amino Acid (tRNA codon) = 3 nitrogenous bases

386 X 3 = 1158 nitrogenous bases

Based on what you know, explain how the covid vaccine worked. SPECIFICALLY, what was injected into us. 

Here’s a brief overview of how mRNA vaccines work:

• mRNA (messenger RNA): These vaccines use a small piece of mRNA to instruct cells in the body to produce a protein that triggers an immune response. In the case of COVID-19 vaccines, the mRNA encodes a blueprint for the spike protein found on the surface of the SARS-CoV-2 virus, which causes COVID-19.

• Immune Response: Once the protein is produced by the cells, the immune system recognizes it as foreign and mounts an immune response. This includes producing antibodies and training T-cells to recognize and attack the virus if the person is exposed to it in the future.
