Answer:
It allowed us to put a formation date on some geologic cross sections
Explanation:
Absolute dating techniques is an improvement on the older relative dating techniques which only give order of past events but with newer absolute dating techniques, those chronological events are sampled and analysed and more accurate numerical ages assigned to them.
This newer technique has vastly improved the way archaeologists find the age of ancient relics and geologists, rocks.

Where does the oxygen and carbon dioxide get exchanged in the respiratory system?
Question 7 options:
bronchi
trachea
bronchioles
alveoli
Answer:
Alveoli
Explanation:
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

By the time a cell has reached metaphase, all the following have occurred except...
Answer:
C. Sister chromatids separate
Explanation:
During interphase, which is composed of the G1 phase, S phase and G2 phase, the cell grows and replicates its DNA and some of its organelles. During the S phase, the genetic material is duplicated into two sister chromatids, and centrosomes, which are nucleated microtubules that interact with the chromosomes to form the mitotic spindle, are also replicated. Metaphase is the third phase of mitosis, where sister chromatids align in the middle of the cell before their separation into two daughter cells.

Rhonda Runsalot is a 20 year old woman. She is running at VO2max. Her heart rate is 200 b/min. Her stroke volume is 100 ml blood/b. Her arterial oxygen content is 20 ml O2/100 ml blood. Her venous oxygen content is 6 ml O2/100 ml blood. What is her cardiac output?
Answer:
Cardiac output = 20 L/min
Explanation:
The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than when resting.
Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min
Cardiac output = stroke volume * heart rate
For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat
heart rate = 200 beats/min
Cardiac output =0.1 L/beat * 200 beats/min
Cardiac output = 20 L/min

If a specific gene code for a polypeptide is 120 amino acids long, approximately how many nucleotides long is the mRNA that codes for this polypeptide?
Answer:
360 nucleotides
Explanation:
Each amino acid corresponds to a specific codon, a sequence of three DNA or RNA nucleotides.
If there are 120 amino acids and a sequence of three nucleotides corresponds to one amino acid, then 120 × 3 = 360 nucleotides.
Hope that helps.
Answer: 360

The biome that fits this description is the Savannah. It is characterized by grassy plains with scattered trees and is home to large herbivores like zebras, who use their herd and stripes as a defense mechanism against predators.
So, the correct answer is C (Savannah).
What are herbivores?
Herbivores are animals that primarily feed on plants, such as leaves, stems, roots, fruits, and seeds. They have specialized digestive systems that are adapted to break down the complex cellulose found in plant cell walls into usable nutrients, such as carbohydrates and proteins. Examples of herbivores include cows, horses, rabbits, deer, and many species of insects, such as butterflies and grasshoppers.
The biome that is home to large herbivores who travel in herds to evade predators and where some animals, like zebras, use their herd and stripes to confuse predators is the Savannah. This biome is characterized by grassy plains with scattered trees and is found in tropical regions. The savannah is home to many large herbivorous mammals such as elephants, giraffes, and antelopes, who form herds for protection against predators like lions, cheetahs, and hyenas. The stripes on zebras' coats help to confuse predators by making it difficult for them to pick out a single target from the herd.
