Answer:
Eventually, as stars age, they evolve away from the main sequence to become red giants or supergiants. The core of a red giant is contracting, but the outer layers are expanding as a result of hydrogen fusion in a shell outside the core. The star gets larger, redder, and more luminous as it expands and cools.

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.

The rainforest is hot, humid, and has frequent rainfall. In what way does the interaction between the atmosphere and the hydrosphere assist in maintaining this type of climate? (SC.6.E.7.2)
AO
The Sun's rays are trapped by the atmosphere, keeping temperatures high for most of the year.
BO
The rainforest is close to the oceans, allowing the hydrosphere to release frequent rainfall.
со
The hydrosphere sends water to the clouds through transpiration, keeping the humidity levels high for most of the year.
DO
The Sun supplies energy for the evaporation and transpiration of water, causing frequent rainfall and hot, humid temperatures.

What could happen if an organism could not maintain homeostasis
When an organism fails to maintain homeostasis, the organism typically becomes ill, and it will die.
what is homeostasis ?homeostasis a self-regulating process in which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival.
If homeostasis is successful, life continues; if unsuccessful, disaster or death ensues, stability attained is actually a dynamic equilibrium, in which continuous change occurs.
Any system in dynamic equilibrium tends to reach a steady state, a balance that resists outside forces of change.

Are covalent bonds responsible for cohesion?
Answer:
A covalent bond is a form of chemical bonding and is characterized by the contribution of one or more pairs of electrons between atoms, resulting in a side attraction that holds the resulting molecule together... Atoms tend to contribute or share their electrons in the way that their electronic shell is full. This bond is always stronger than the intermolecular forces like the hydrogen bond...

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.

___________ helps scientists understand processes in the natural world by providing simpler representations of those processes.
Answer:

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.

What is the most noticeable differences between the Hadeon period of

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.
