Lifeforms have changed throughout Earth's geologic history. Scientists learn about these changes by studying the fossil record. For example, scientists have learned when different groups of organisms first appeared. These events can be placed within specific periods on the geologic time scale, which is shown below.
Fishes with jaws first appeared during the Silurian period, and dinosaurs first appeared during the Triassic period. Large mammals first appeared after both dinosaurs and fishes with jaws.
Using this information and the geologic time scale above, choose the period in which large mammals first appeared.
A.
Permian
B.
Ordovician
C.
Tertiary
D.
Cambrian
Answer:
C. Tertiary
Explanation:
mammals have fur unlike the others period animals
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 is a solar storm and a solar flare?The sun is a gigantic thermonuclear reactor that eventually fires huge amounts of concentrated radiation in the form of particles in a constant stream called the "solar wind".
A geomagnetic storm can last just a few minutes, or several hours, but the effects of geomagnetic storms can linger in the Earth's magnetosphere and atmosphere for days to weeks. The storm also results in a rapid drop in the strength of Earth's magnetosphere for a period of between 6 and 12 hours. Then the magnetic field gradually recovers over a few days.

Neurons in which dendritic and axonal processes are continuous and the soma lies off to one side are called.
The neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.
What is a unipolar neuron?The neuron is the structural and functional unit of the nervous system, which when they have only a short projection that later branches into two or more branches, are considered unipolar.
That is, they are those neurons in which only one extension or neurite emerges from the soma, which will act as an axon and at the same time will have dendrites with which it can both receive and transmit information.
Therefore, we can conclude that the neuron is a highly specialized type of nervous system cell that is called unipolar when dendritic and axonal processes are continuous and the soma lies off to one side.

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

7. Discuss the practical and theoretical differences between an interval training program used to improve the ATP-PC system and a program designed to improve the ATP production via glycolysis.
The ATP-phosphocreatine (PC) system is more suitable in conditions of high energy expenditure, whereas glycolysis is a step during cellular respiration.
What is cellular respiration?Cellular respiration is a chemical process by which aerobic cells generate energy in the form of ATP by using foods as a source of energy in presence of oxygen.
During cellular respiration, glycolysis (glycolytic pathway) is the first step for ATP production.
The ATP-PC system is anaerobic, works in hypoxia conditions (oxygen absence), and is faster to provide energy than cellular respiration.
However, the ATP-PC system is energetically less efficient than cellular respiration in terms of the number of ATP molecules produced per unit of glucose.

A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.
Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.

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.
