What is the most noticeable differences between the Hadeon period of
Earth with any other period of Earth?
Answer:
Hadean ("Hades-like") Era. This era began with the formation of the earth from dust and gas orbiting the Sun about 4.6 billion years ago. During this era the surface of the Earth was like popular visions about Hades: oceans of liquid rock, boiling sulfur, and impact craters everywhere, meanwhile, during, for example, the Cretaceous period, Earth's land assembled essentially into two continents, Laurasia in the north and Gondwana in the south. These were almost completely separated by the equatorial Tethys seaway, and the various segments of Laurasia and Gondwana had already started to rift apart, and there were oceans of seawater, teeming with life such as Mosasaurs and Ammonites. During the Cretaceous period, the land was hospitable and warm enough to support large numbers of lifeforms, including the dinosaurs.

Cohesion and adhesion are responsible for which of the following concepts?
Dehydration synthesis
Capillary action
Dry-ice
Polarity
Answer:
K I'm not sure about this one, but it should be capillary action
Explanation:
This is because cohesion and adhesion have to do with water stick to surfaces. Capillary action occurs because of how the water sticks and bonds to certain surfaces. Cohesion is how water molecules stay together, while adhesion is how water molecules are attracted to other molecules.
Which of the following is true of the structures labeled C in the cell membrane?
Choose 1 answer:

Answer:
There's not really an age to RNA. It depends on how old the human/animal is.
Why is it Important that cell membrane contain openings into cell ?
Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.

Ribosomes produce proteins in cells; however, the type of protein that ribosomes produce depends greatly on where they can be found in the cell. Ribosomes found in the cytoplasm produce proteins that aid in chemical reactions. The other type of ribosomes are found in the _____________________ and produce proteins that ______________________.
A. Golgi Apparatus; repair broken organelles
B. Endoplasmic Reticulum; repair broken organelles
C. Endoplasmic Reticulum; store and transport nutrients
D. Golgi Apparatus; store and transport nutrients
The other type of ribosomes are found in the endoplasmic reticulum and produce proteins that store and transport nutrients.
What is an endoplasmic reticulum?
An endoplasmic reticulum is an membrane bound cell organelle found in the cell cytoplasm.
Its one end is connected to the nucleus and other end is connected to the golgi body.
Endoplasmic reticulum is a membranous structure. The membranes are flat and form a network (cisternae).
Endoplasmic reticulum is present in all the cells in the body except RBCs and spermatozoa.
Endoplasmic reticulum consists of two subunits:
Rough endoplasmic reticulum (RER) - ribosomes are present on the surface.Smooth endoplasmic reticulum (SER) - ribosomes are absent.Endoplasmic reticulum is important for protein synthesis and protein folding.
Endoplasmic reticulum is important in the storage of calcium.
It also helps in the detoxification of drugs and lipid metabolism.
Therefore, endoplasmic reticulum is crucial for the manufacturing, storage and transport of proteins.

Which will increase the rate of a chemical reaction?
adding a catalyst
decreasing the pressure
decreasing the temperature
removing a catalyst
Answer:
Addition of a catalyst
Explanation:
A catalyst tends to alter the rate of a chemical reaction thereby increasing the rate of the reaction
Adding a catalyst will increase the rate of a chemical reaction. Therefore, option (A) is correct.
What are the functions of catalyst?A substance known as a catalyst is one that, without being consumed during the reaction, accelerates or reduces the temperature or pressure required to initiate a chemical reaction.
A substance which when utilized in limited quantity in responses changes the pace of a reaction without being consumed in the actual response is known as an impetus and this peculiarity is known as Catalysis.
Without actually participating in the reaction, catalyst is used to speed it up. The reaction rate is sped up by catalyst, but the equilibrium constant remains unchanged.

___________ helps scientists understand processes in the natural world by providing simpler representations of those processes.
Answer:
models
Explanation:
Scientific models help scientists understand the processes in the natural world by providing simpler representations of those processes.
What are scientific models?A physical, mathematical, or conceptual representation of facts, data, processes, etc to be used as an aid for understanding the said facts, methods, or data are called scientific models.
These scientific models are used by scientists to comprehend or recognize various processes in our world by referencing their scientific knowledge which helps them to better understand and then explain any observable pattern.
Scientific models need to be consistent with the existing explanations or observations. Scientific models are based on facts but they cannot be considered ultimate facts themselves.
Scientific models can be consensus models, mental models, or expressed models based on their representation.
Therefore, the aid used by scientists to properly understand the natural world by providing simpler representations of those processes is called scientific models.
