Tertiary is the period in which large mammals first appeared.
What is Tertiary period?The Cenozoic era's initial geological phase is the tertiary, which is also known as the Paleogene and Neogene periods. Between 66 million and 2.6 million years ago, there was a geological epoch called the Tertiary.
The Cretaceous-Paleogene extinction catastrophe at the beginning of the Cenozoic Era marked the start of the Tertiary Geological Period, which lasted until the Quaternary Glaciation at the end of the Pliocene Epoch.
The tertiary period began approximately 66 million years ago with the extinction of the dinosaurs, and it ended when the Quaternary Period's ice ages started, or roughly 2.6 million years ago.
Therefore, Tertiary is the period in which large mammals first appeared.

What 4 body systems are used for CLEANING
YOUR ROOM?
List each body system (4 systems should be
listed) and explain how each system helps the
body when you clean your room.
Here are the body systems we talked about in class. Use this list to help you recall the types of systems
in the body: Muscular System, Skeletal System, Nervous System, Circulatory System, Digestive System,
Immune System, Reproductive System, Integumentary System, Respiratory System, Excretory System
Answer:
The skeletal system:This system controls our bones so we aren't just a blob on the ground. Our bones help keep our important organs intact.
The muscular system works about the same way, it protects your bones so they don't grind against eachother when you move. Your muscles give you the ability to move.
Our organ system is what keeps us alive, you can't clean your room if your dead and if your room is hot you need your skin so you don't overheat and die.
Lastly of course is your respitory system, you need to bring when your moving about. Our ability to breathe gives our blood cells and our heart what they need to keep working.

VOLUME
Why does the first method for determining volume work only for a regular-shaped object?
Will the second method for determining volume work for any object or just an odd-shaped one?
Why?
Is one method of measurement more accurate than the other? Why or why not?
Would the displacement method of measurement work for a cube of sugar?
What about a cork? Why?
What did you find out from this investigation? Be thoughtful in your answer.
.
Answer:
1. Because only regular-shaped objects have a consistent length, width, height, and shape. When dealing with an object composed of differing shapes, you must calculate each portion separately and then add them. For instance, if you have a swimming pool of two depths and want to determine cubic feet, you would have to calculate the volume for each section and then add them.
2. method used to figure the volume of an irregular shaped object Neither measurement is more "accurate" than the other--they simply denote different things. Length is a measurement of the distance between two points in space. The area is a measurement of the surface covered by a given shape.
3. not in the water as the sugar would dissolve if you could find a liquid that sugar does not dissolve in, then it would work
Explanation:
How does the nucleus work with the ribosomes to maintain the structure and function of a cell?
Answer:
The nucleolus within the nucleus produces ribosome subunits, which are assembled outside the nucleus into ribosomes. The nucleus then sends mRNA to the ribosomes, which is used to code for protein synthesis.

Answer:
Endometrium
Explanation:
Concentrated animal feeding operations that raise hundreds of animals in a single location often use manure lagoons to dispose of the manure. manure lagoons are ponds lined with rubber to prevent the manure from leaking into groundwater or nearby waterways. one pig produces 30 liters of manure each day, and the average feedlot holds 900 pigs. calculate the amount of manure produced by the feedlot after 30 days to determine the minimum capacity needed for a manure lagoon. a faulty manure pond leaks into a nearby lake. describe one effect this leak would have on the organisms living in the lake.
If there is a leakage of the manure pond into the near by river, the growth the nitrates and phosphates in the leak causes an overgrowth of algae leading to eutrophication.
What is a manure?A manure is that which is used to improve the fertility of the soil. It is composed of the nutrients that are required by the soil. We know that each pig produces 30 liters of manure each day, and the average feedlot holds 900 pigs. Hence, each day, 30 * 900 = 27000 litres of manure is produced.
Within a period of 30 days, a total of 27000 litres of manure * 30 = 810,000 litres of manure is produced. If there is a leakage of the manure pond into the near by river, the growth the nitrates and phosphates in the leak causes an overgrowth of algae leading to eutrophication.

In all the crosses the two genes under investigation were on different chromosomes. If the two genes were on the same chromosome rather than different chromosomes, how would that have affected the results?.
Answer:
When genes are close together on the same chromosome, they are said to be linked. That means the alleles, or gene versions, already together on one chromosome will be inherited as a unit more frequently than not.
Explanation:
:)
When genes are close together on the same chromosome called as linked genes, means the alleles present together on one chromosome and it will be inherited as a unit.
What is chromosome ?A chromosome is located in nucleus of the cell is the main carrier of genes or DNA; It is a thread-like structure observed in plant, animal and human cells and composed of molecule of DNA (Deoxyribonucleic acid) and histone proteins.
DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and RNA content ranges from 1 to 10% in chromosome.
There are Two types of protein present such as histone and non-histones proteins where histone protein constitute portion (90% of total protein), whereas non-histone protein occupy a small portion (around 10% of total protein).
The histone protein is basic in nature, whereas, the DNA is acidic, so neutralization occur, DNA in chromosome can be present as forms such as Euchromatin and Heterochromatin.
