There are two clusters of Amazonian trumpeter species on the phylogenic tree because the main population of the common ancestral species was divided into two different, isolated populations. This is from them that all the other species evolved.
The trumpeters refer to a family of birds found in humid forests of the Amazon and Guiana Shield in South America. Their name has an interesting reason. It is said that they are named for the trumpeting or cackling threat call of the males
Identify four organelles that should be present in the eukaryotic organism and describe the function of each organelle.
Final answer:
The eukaryotic organism contains organelles such as the nucleus, mitochondria, endoplasmic reticulum, and the Golgi apparatus, which function in controlling cellular activity, producing energy, synthesizing proteins, and processing cellular products, respectively.
Explanation:
Four organelles that should be present in a eukaryotic organism and their functions are as follows:
Nucleus: Acts as the control center of the cell, housing the DNA and coordinating activities such as growth, metabolism, and reproduction.Mitochondria: Known as the powerhouses of the cell, mitochondria are where oxidative phosphorylation occurs to produce ATP, the cell's energy currency.Endoplasmic Reticulum (ER): Divided into rough ER, which is involved in protein synthesis and folding due to the presence of ribosomes, and smooth ER, which is important for lipid metabolism and detoxification processes.Golgi Apparatus: Functions in modifying, sorting, and packaging of proteins for secretion or use within the cell.These organelles are crucial for the function and maintenance of eukaryotic cells, enabling the segregation of various biochemical processes.

A pond near a city park is found to be contaminated with both bacteria and excess nitrogen. The bacteria most likely came from _____, and the excess nitrogen most likely came from _____.
sediment; pesticides
animal waste; fertilizers
inorganic metals; sediment
runoff; sewage
Answer: A pond near a city park is found to be contaminated with both bacteria and excess nitrogen. The bacteria most likely came from animal waste,and the excess nitrogen likely came from fertilizers.
The bacteria will be most likely to come from animal waste as numerous bacteria lives in the intestine and stomach of these animals, which facilitate the digestion of food, these bacteria come along the animal feces after digestion. Also, there are bacteria which degrade the animal feces. Bacteria may also degrade and may be present on other animal wastes like left out skin, tissues, hair, fur. Nitrogen is the chief constituent of fertilizers. Nitrogen increases the fertility of soil and it can be a potent pollutant for a water body.

Which of these shows he correct order to the central dogma of molecular biology . Answer is D . DNA to RNA to protein . Why is the answer D ???
Answer:
The answer is D! Can you mark me brainliest? Im trying to level up.
Explanation:
The answer is D, DNA to RNA to protein, because this is the correct order of the central dogma of molecular biology, which describes the flow of genetic information within a biological system.
What enzyme is responsible for RNA making from DNA ?In this process, DNA (deoxyribonucleic acid) is transcribed into RNA (ribonucleic acid) by an enzyme called RNA polymerase, and then the RNA is translated into a protein by ribosomes.
This process is fundamental to all living organisms, and it allows for the transfer of genetic information from one generation to the next. The central dogma is a critical concept in molecular biology and is essential to understanding many biological processes, including genetic disorders and diseases.
The central dogma of molecular biology describes the flow of genetic information within a biological system. It states that DNA is transcribed into RNA, and RNA is translated into proteins. This process occurs in all living organisms and is essential for the function and survival of cells.
The correct order in the central dogma of molecular biology is DNA to RNA to protein. This means that DNA serves as a template for the synthesis of RNA molecules in a process called transcription. The RNA molecules are then transported from the nucleus to the cytoplasm, where they serve as templates for the synthesis of proteins in a process called translation.
The order of the central dogma is important because it ensures that genetic information is properly transmitted from DNA to proteins. Any errors or changes in this process can lead to mutations or other genetic disorders.
Therefore, understanding the central dogma is essential for understanding how genetic information is expressed in cells and how it can be manipulated for various applications in biology and medicine.

A fully functioning enzyme molecule is arranged in a complex three-dimensional shape. this shape determines the
Types of molecules that interact with each other during the reaction.
Further explanationEnzymes are composed of 2 parts:
a. Apoenzim parts are enzymes composed of proteins. Apoenzim is a type that dominates from all kinds of enzyme structures. Its unstable nature is easily changed when influenced by temperature and pH.
b. Parts of prosthetic groups are enzymes arranged on the basis of nonprotein. Based on the constituent, prosthetic there are two more parts, namely:
Coenzyme: Its job is to transfer chemicals from one enzyme to another.
Cofactor: Its job is to optimize the ptialin enzyme in breaking down complex sugar molecules.
Like all proteins, enzymes are made for very long, linear chains of amino acids that are folded to produce a three-dimensional product. Each unique amino acid produces a specific structural sequence, which is unique. Individual protein chains are sometimes grouped together to form complex proteins. Most enzymes can be denatured, stretched and inactivated by heating or chemical denaturation, disrupting the structure of the three dimension proteins. Depending on the enzyme, denaturation may not be changed or reversible.
Enzymes have 4 properties, namely:
1. an enzyme resembling a protein
2. Enzymes work back and forth
3. Enzymes work specifically
4. Enzymes are biocatalysts

Fats are specialized lipid molecules, and enzymes are specialized protein molecules. How do the functions of fats and enzymes differ?
A. Fats provide support for cells, while enzymes lower the pH of gastric fluids.
B. Fats are structural building materials, while enzymes are transportation molecules.
C. Fats are storage molecules, while enzymes are catalytic molecules.
D. Fats regulate body functions, while enzymes denature invasive bacteria.
Explain why.
Answer:
The correct answer is C. Fats are storage molecules, while enzymes are catalytic molecules.
Explanation:
Fats are primarily made up of carbon and hydrogen atoms which makes it hydrophobic in nature. Fat are macronutrient and they is stored on the liver which are utilized by the body in the scarcity of glucose and glycogen in the body. Fats can provide more calories that amino acids and glycogen after oxidation.
Enzymes are catalytic molecules that can regulate the reaction rate. Most of the enzymes increase the rate of the reaction and helps in completion of a metabolic process. Enzymes in the human body works more efficiently at 37°c.
Therefore fats are used for storage purpose and enzymes are used to catalyze a reaction. So the right answer is C.

In vertebrates, which biological system carries out more chemical reactions than any other organ or system?
Answer:
Digestive System
Explanation:
The digestive system is responsible for the process of digestion, that is, processing and absorption of food in order to meet the needs of all cells. The proper functioning of this system is due to two important aspects:
- Compartmental, that is, as much as the various organs that make up this system are physically linked, they still have, within certain limits and harmony, independence of functioning. In other words, each organ will perform a particular function even though it is connected to other structures;
- Enzymatic, that is, the food will pass through the different organs and, as a result, will undergo the enzymatic action of different enzymes in each region.
A valid caveat is that during the digestion process physical and chemical changes occur with the food, which aims to create chemical structures and the ideal physical condition to be absorbed.
