how ribosomes help cell maintain homeostasis
Answer:
Ribosomes create the thermoreceptors of the body. Another example of a homeostatic condition maintained by proteins is blood-glucose levels. When our blood-sugar levels get too high, specialized cells in the body release a protein hormone called insulin.
Explanation:

~Zero~
Answer: Ribosomes play a key role in homeostasis. Without ribosomes, a cell would not make proteins. A cell with no ribosome would simply not function. With no protein reproduction to maintain the cell wall there would be no barrier to keep invasive bodies from damaging the inner workings of the cell, there would be no way to produce the needed proteins for rebuilding and maintaining the cell.

Record the elements present in each unknown astronomical object. Be sure to indicate “yes” or “no” for each element.
Hydrogen Helium Lithium Sodium Carbon Nitrogen
Moon One
Moon Two
Planet One
Planet Two
We record the elements present in each unknown astronomical object according to metallicity.
Moon one - HeliumMoon two - SodiumPlanet one - Hydrogen -Carbon Planet two - Lithium - Nitrogen
To understand these answers, we need to know what metallicity.
What is metallicity?In astronomy and physical cosmology, metallicity (also called Z) of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium. Because stars, which make up most of the visible matter in the universe, are composed primarily of hydrogen and helium, astronomers conveniently use the generic term "metal" to describe all other elements collectively.
With this information, we can conclude that we have recorded the elements present in each unknown astronomical object according to metallicity.

Selection that acts over evolutionary time to preserve traits that increase an individual's ability to mate is known as __________.
The selection that acts over evolutionary time to preserve traits that increase an individual's ability to mate is known as se_xual selection.
What is se_xual selection?The expression 'se_xual selection' makes reference to the type of evolutionary constraint on the individual's ability to mate.
Se_xual selection is fundamental to increase the genetic variation and thus enhance adaptive chances.
Se_xual selection can be considered a special type of natural selection that acts at an individual level.

How does emissions of carbon dioxide impact climate change?
Answer:
The carbon emissions trap solar energy in the atmosphere which causes global temperatures to increase, this is also called the greenhouse effect. Since the global temperatures will increase, ice in the polar regions will melt causing the water level to increase leading to an influx of problems.

Which statement BEST describes what happens during the S-phase of the cell cycle?
A.Protein synthesis needed for spindle formation and mitosis.
B.DNA replication where the amount of genetic material is doubled.
C.The cell partitions the two copies of genetic material into the two daughter cells.
D.Cell division occurs and two cells are left; thus the cell cycle begins again.
Answer:
B
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
A growth chart is used in monitoring the growth and development of a child. the star on the chart represents a girl who is at the doctor for a routine check-up. judging by the location of the star, should the doctor conduct tests to examine her pituitary gland?
No, her height is within normal range, and her pituitary gland is working normally.
Why is the pituitary gland called the master gland?The pituitary gland is occasionally called the "master" gland of the endocrine system because it maintains the functions of many of the other endocrine glands.
The pituitary gland is no larger than a pea and is found at the base of the brain.
Thus, her height is within normal range, and her pituitary gland is working normally.

Answer:
The answer would-be producers. The fact that there are primary consumers today, you would know that producers make up the bigger population.

3. How is heat transferred within the Earth?
(5 Points)
O A. by conduction
O B. by radiation
O C. By seismic waves
O d. by gravity
the answer is D
"During convection, heat is being transferred between substances in direct contact with each other by electro magnetic waves."
"Using the molten rock to explain the convection in the earth relative to how if affects the weather condition. Here, the rock is in a molten state, rising up from the bottom of the mantle after becoming hotter and less dense from the heat of the earth's core. As the rock loses heat into the earth's crust, it become cooler and more dense,sinking back to the core. These constantly circulating cells of hotter and cooler molten rock help to heat the earth's surface."
