What is one way secondary succession differs from primary succession?answer choicesA. Secondary succession is typically quicker than primary successionB. Secondary succession is typically slower than primary successionC. Secondary succession only occurs in mountains, primary succession only occurs in wetlandsD. Secondary succession is the gradual change in plant species, while primary succession is the gradual change in animal species

Answers

Answer 1

The one way secondary succession differs from primary succession: Secondary succession is typically quicker than primary succession. The correct option is (A).

Secondary succession refers to the sequence of changes that occur in an ecosystem that has been disturbed or disrupted, but still retains its soil.

In this process, the existing community is destroyed or removed by a disturbance such as a forest fire, flood or human activities such as logging or farming.

However, the soil and seeds of plants remain, so the recovery process is quicker than primary succession.

On the other hand, primary succession occurs in an area where no life existed before, such as after a volcanic eruption or glacial retreat. The process of primary succession involves the creation of new soil, which takes a longer time to form and support plant growth.

The first organisms to colonize such areas are usually lichens and mosses, which gradually pave the way for more complex plants, leading to a longer and slower process.

In summary, secondary succession occurs in areas where an ecosystem has been disturbed, while primary succession occurs in areas where no life existed before, making it a slower and longer process.

(a) endosymbiosis has been proposed as a model for the evolution of eukaryotic cell structure. identify and explain two pieces of evidence that support the endosymbiotic theory.

Answers

Two pieces of evidence that support the endosymbiotic theory are the proof of DNA in mitochondria and chloroplasts and living organisms showing endosymbiosis even today.

The endosymbiotic theory suggests that eukaryotic cells evolved from simpler prokaryotic cells that formed mutually beneficial relationships with each other. Two pieces of evidence that support this theory are:

1. Mitochondria and chloroplasts have their own DNA: Mitochondria and chloroplasts, the organelles responsible for energy production in eukaryotic cells, contain their own DNA. This DNA is similar to that of bacterial DNA, supporting the idea that these organelles were once free-living bacteria that were engulfed by a larger cell. The fact that these organelles have their own DNA also suggests that they are capable of replicating and dividing independently of the rest of the cell.

2. Endosymbiosis can be observed in living organisms: Endosymbiosis is not just a theoretical concept; it can be observed in living organisms today. For example, many species of single-celled protists contain endosymbiotic bacteria that help them to digest food or provide nutrients. In some cases, these bacteria have become so integrated into the protist's cell structure that they have lost their ability to live independently. This provides evidence that endosymbiosis can lead to the evolution of new cellular structures and functions over time.

The function of the levator scapula is to elevate the scapula and assist in various movements of the shoulder girdle, including shrugging the shoulders, rotating the neck, and tilting the head to the side. It also helps in stabilizing the scapula during arm movements.

The levator scapula is a muscle located at the back and side of the neck. Its primary function is to elevate the scapula, or shoulder blade. The levator scapula works in conjunction with other muscles to allow movements of the shoulder girdle.

One of the main actions of the levator scapula is shrugging the shoulders. When you raise your shoulders towards your ears, the levator scapula contracts to elevate the scapula.

In addition to shrugging, the levator scapula also helps in rotating the neck. When you turn your head to the side, the levator scapula on that side contracts to assist in the movement.

The levator scapula is also involved in tilting the head to the side. When you tilt your head towards one shoulder, the levator scapula on the opposite side contracts to stabilize the scapula and assist in the movement.

Furthermore, the levator scapula plays a role in stabilizing the scapula during arm movements. It helps to keep the scapula in the correct position, allowing for smooth and coordinated movements of the arm.

The correct answer is iterative evolution. A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of iterative evolution.

Iterative evolution is the development of similar structures or forms independently over time in separate lineages. This is frequently seen in unrelated lineages of organisms that evolve similar features through convergent evolution. The crocodile-like morphology that evolved independently in Triassic reptiles called phytosaurs and later in true crocodiles is an example of iterative evolution as they evolved independently in separate lineages. The ability of the phytosaurs to thrive in an aquatic environment likely contributed to the development of this morphology, which later allowed true crocodiles to similarly thrive.

2. describe the mechanical events (pressure changes, volume changes, valve activity, and heart sound) of the cardiac cycle.

Answers

During the cardiac cycle, the heart undergoes sequential pressure changes and volume changes, facilitated by coordinated valve activity, resulting in the generation of distinct heart sounds.

The mechanical events of the cardiac cycle consist of pressure changes, volume changes, valve activity, and heart sound.

These events can be grouped into two phases: diastole and systole.

The cardiac cycle refers to the series of events that occur during one heartbeat.

This process lasts approximately 0.8 seconds and is divided into two phases, namely diastole and systole.

During diastole, the heart muscle relaxes and fills with blood.

The following events occur during diastole: The aortic and pulmonary valves are closed. The mitral and tricuspid valves are open.

Blood flows from the atria into the ventricles. The volume of the ventricles increases.

The pressure in the atria is greater than the pressure in the ventricles. This causes blood to flow through the mitral and tricuspid valves into the ventricles.

The ventricles contract during systole, and the following events occur: The mitral and tricuspid valves are closed.

The aortic and pulmonary valves are open. Blood is forced out of the ventricles into the arteries.

The volume of the ventricles decreases. The pressure in the ventricles is greater than the pressure in the arteries. This causes blood to flow through the aortic and pulmonary valves into the arteries.

Heart sounds are created by the closing of the heart valves.

The first heart sound is created by the closure of the mitral and tricuspid valves, and the second heart sound is created by the closure of the aortic and pulmonary valves.

The mechanical events of the cardiac cycle are essential for the proper functioning of the heart and the circulatory system as a whole.

The majority of the time the human body utilizes aerobic cellular respiration to meet its energy needs as opposed to anaerobic cellular respiration. Why

Answers

The majority of the time the human body utilizes aerobic cellular respiration to meet its energy needs as opposed to anaerobic cellular respiration because aerobic cellular respiration is more efficient than anaerobic cellular respiration in generating energy. The aerobic cellular respiration is the preferred method of energy production by the human body.

Aerobic cellular respiration occurs in the presence of oxygen, while anaerobic cellular respiration occurs in the absence of oxygen. Aerobic respiration involves the breakdown of glucose to produce ATP, while anaerobic respiration involves the breakdown of glucose or other molecules in the absence of oxygen to produce ATP.During aerobic cellular respiration, the glucose is broken down into pyruvate which enters the mitochondria and undergoes the Krebs cycle. This process produces a large amount of ATP, and carbon dioxide and water are released as waste products. On the other hand, during anaerobic cellular respiration, glucose is broken down into lactic acid, which does not produce as much ATP as aerobic cellular respiration and lactic acid builds up as waste products in muscles. Hence, aerobic cellular respiration is the preferred method of energy production by the human body.

Answers

Annull mutation in which of these genes would cause ABC protein to be produced at normal levels but in the wrong location is MP. The main answer is MP.

ABC gene produces mRNA encoding the ABC protein, and ZBP1 protein binds Abc mRNA and prevents its translation. MP (motor protein) transports ZBP1-bound mRNA to its destination, while Src protein is located at the destination and causes ZBP1 to dissociate from mRNA, allowing it to be translated.

In a mutation, the characteristics of DNA are altered, resulting in different genes being expressed or the production of altered proteins. A mutation in the MP gene can cause the protein to be produced at normal levels but in the wrong location. As a result, mRNA bound with ZBP1 would not be transported to its destination.

The type of mutation that would interfere with the attenuation mechanism in the tryptophan operon is the deletion mutation. In the tryptophan operon, the attenuation mechanism is used to regulate the synthesis of tryptophan. When the tryptophan levels are low, the operon is activated, and transcription takes place, allowing the synthesis of tryptophan. When tryptophan levels are high, the attenuation mechanism is activated, and transcription is halted. A deletion mutation, which removes one or more nucleotides from the DNA sequence, can interfere with the folding of RNA, resulting in a premature termination of transcription, which will cause attenuation to fail.
