Answer:
66 million years ago
Explanation:
The age of dinosaurs, has been discovered. The tiny fossil, nicknamed the "wonderchicken," includes a complete skull hidden inside pieces of rock, and dates to more than 66 million years ago.
Answer: Now that you know how many half-lives have passed for your fossil, you need to multiply your number of half-lives by how many years are in one half-life. This gives you an age of 2 x 5730 = 11,460 years.

The concave surface of the lungs where blood vessels, lymphatic vessels, nerves and the primary bronchi enter and leave contains a slit called the HILUM. It is also known as the root region.
The hilum (root region) is the point at which bronchi, pulmonary arteries and pulmonary veins enter into the lung.
Each hilum (left and right) has a pulmonary artery, pulmonary veins, and bronchial arteries.
The hilum or root region connects the lungs to supporting structures where pulmonary vessels enter and exit the lungs.

A-Methane
B- Hydrogen sulfide
C- carbon dioxide
D- light photons
Chemosythesis involves inorganic chemicals therefore, light photons are not required during chemosynthesis.
Chemosynthesis refers to the process by which some organism obtain food from inorganic chemicals rather than from light. There are many chemosynthetic bacteria that obtain food by the metabolism of methane, hydrogen sulfide or carbon dioxide.
Light photons are not required for chemosynthesis. It is only necessary during photosynthesis.

1. Given the distribution of charges shown in this water molecule, why is it called "polar"?
Answer:
Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding

aminoacyl-trna synthetase is an enzyme whose function is to _____.
Answer:plays a critical role in protein synthesis,
Explanation:
Aminoacyl-tRNA synthetase is an enzyme whose function is to attach the appropriate amino acid to its corresponding transfer RNA (tRNA) molecule, creating an aminoacyl-tRNA complex that will be used in protein synthesis.
What is Aminoacylation?Aminoacylation, also known as tRNA charging, is a biochemical process in which an amino acid is attached to its corresponding transfer RNA (tRNA) molecule. This process is catalyzed by the enzyme aminoacyl-tRNA synthetase, which recognizes the specific amino acid and the corresponding tRNA molecule that carries the anticodon sequence for that amino acid.
Aminoacylation is a crucial step in the process of protein synthesis, as the charged tRNA molecule brings the amino acid to the ribosome during translation, allowing the amino acid to be incorporated into the growing polypeptide chain.
The accuracy and efficiency of aminoacylation are critical for ensuring that proteins are correctly synthesized, as errors in aminoacylation can lead to the misincorporation of amino acids and the synthesis of non-functional or improperly folded proteins.

What does "endemic" mean? Why are there so many different types of endemic plants in California?
Answer:
Endemic: Belonging or native to a particular people or country
Due to specific chemical and physical characteristics of the soils, these habitats are nutrient-poor, and this has led to the establishment of a highly specialized and diverse flora. It has been estimated that serpentine endemic plant species represent 10 percent of the California Floristic Province's endemics.

The statement which represents a common problem of urbanization is that most homes are built with poor materials or in dirty or unsafe living conditions. Thus, the correct option for this question is C.
What is deforestation?Deforestation may be defined as the process of elimination of trees and forests for the purpose of urbanization and industrialization along with various human activities. It is the purposeful clearing of forested land.
The great impact of deforestation is that it decreased wildfires. When the number of trees gradually declines, the chances of forest fires and wildfires may also reduce with respect to time. But there is an ultimate increase in pollution that may be observed along with habitat defragmentation.

Answer:
True
Explanation:
Information about the four organisms can be found on the Internet. Use credible websites to find answers to the questions you developed in part A. Based on this data, draw your own dichotomous key.
Based on the key you created, do you think some of the organisms are more closely related than others? Explain your answer.
Part 1 was this:A dichotomous key works on the principle of asking yes-or-no questions about the organism. To identify it, the answers for that organism are then compared to existing organisms to identify it. Prepare a list of four to five questions about each of the organisms listed below to help you create your own key. For each question, make sure the answer isn’t the same for all four organisms. For example, Does the organism have cells? would be an inappropriate question, because all the organisms have cells.

This may not exactly align with your answer but here's the key and I wrote for Part E:
Explanation:
Part E: Yes, I think that there are some closely related species of organisms that cannot be identified with a dichotomous key. Dichotomous key is used to classify objects or organisms based on its physical characteristics. Because of that limitation, there are species that may be related according to the dichotomous key but are in fact not or its relation is very minimal whereas there are organisms that may seem unrelated based on their physical characteristics but are actually from the same ancestors.

Answer:
When the star runs out of hydrogen the core's temperature decreases so the thermal pressure decreases as well. With a result of the core becoming less efficient to hold up the rest of the star's weight. The core and the gas around it starts shrinking As this happens, the gas in the core and shell around it heats up. Then the star is becomes a supernova.
