Explanation:

Answer 2

The second student set up solutions that were in equilibrium.

On which principle Dialysis is based?

Dialysis is based on the principles of osmosis, meaning the net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration. If the solute concentrations are the same on each side of the membrane, this spontaneous movement will not occur.

In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing  molecules of water to diffuse across the membrane along the concentration gradient.

Therefore, the second student set up solutions that were in equilibrium.

Answers

Answer:

In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The process begins when the enzyme RNA polymerase binds to a region called the promoter.

Explanation:

I took the test lol

Transcription is a particularly important stage in gene expression, since it is the main method by which the cell regulates which proteins are to be created and at what rate.

What is the role of enzyme in the transcription process?

RNA polymerase, which creates a complementary strand of RNA using a single-stranded DNA template, is the primary enzyme involved in transcription.

Each new nucleotide is added to the 3' end of the strand as RNA polymerase constructs an RNA strand in the 5' to 3' orientation.

The first step in unlocking a cell's genetic code is transcription. Enzymes known as RNA polymerases construct complementary RNA molecules to a section of one strand of the DNA double helix during transcription.

Therefore, In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The RNA polymerase enzyme binds to a region known as the promoter to start the process.

Answer:

Hi There!

Explanation:

1 to 8 km/sec

S-waves are transverse waves. Even though they are slower than P-waves, the S-waves move quickly. Typical S-wave propagation speeds are on the order of 1 to 8 km/sec. The lower value corresponds to the wave speed in loose, unconsolidated sediment, the higher value is near the base of Earth's mantle.

Rico and Bree are camping and have potatoes wrapped in foil to eat. Bree put her potato in the campfire for a while, but Rico did not. Now Bree's potato has a high temperature. What is the difference between the molecules of the two potatoes? *

Answers

There is no difference because both potatoes are made of the same type of molecules.

What is Molecules?

Molecule is a group of two or more atoms that are bound together with the help of some attractive forces. These attractive forces are known as chemical bonds. It is the smallest particle of a substance that has all the physical and chemical properties of that substance.

Atoms have a single nucleus with a positive charge protons surrounded by a cloud of negatively charged electrons. When these come close to each other, the electrons interact with each other and with the nucleus, lowering the total energy of the system, then the atoms bond together to form a molecule.

There are three types of molecules:

1. Molecule of an atom

2. Molecule of an element

3. Molecule of a compound

Thus, there is no difference because both potatoes are made of the same type of molecules.

Answers

Answer:

Antecubital

Explanation:

In technical anatomical terms, antecubital refers to the area anterior to the elbow—meaning the opposite side. In the human body, the antecubital area is where the humerus (upper arm bone) connects to the radius and ulna bones of the forearm.

The term used to describe the front of the elbow is:  Antecubital  fossa

Antecubital fossa is the term used to describe the front surface of the elbow. this area is important in the human arm because it is the area where the upper arm bone connects with the bones of the forearm ( ulna and radius ).

The name Antecubital fossa is derived from the Latin name Cubitus

 

During the insertion of IV into the human body or during blood donation, the Antecubital area is very vital because veins can be easily located around the area than any other part of the body.  

Hence in conclusion the term used to describe the front of the elbow is Antecubital.

Question # 9
Multiple Choice
Which of the following best characterizes the global role of photosynthesis in relation to global warming?


reproduction

circulation

respiration

digestion

Answers

Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.

Poison dart frogs live in the rainforest. They produce a poison by eating toxic fire ants. The only known predator is a snake, Liophis epinephelus. Which is most likely a density-independent factor that affects the poison dart population in the rainforest? clear cutting the rainforest limited food source susceptibility to disease increase in population of Liophis epinephelus

Answers

Answer:

Clear-cutting the rainforest

Explanation:

Density-independent factors of a population are factors that limit the size of a population irrespective of the density of the population.

A limited food source can only be defined by the size of a population, diseases will spread faster in high-density populations, and an increase in the population of a predator will cause a decrease in the population size of the predator's prey.

Clear-cutting of the rainforest means automatic destruction of the habitat of the poison dart frog's population, no matter the population size. Hence, clear-cutting of the rainforest is considered as the density-independent factor in this case.

A.) clear cutting the rainforest
