Most of the confirmed hypotheses found to be fabricated were the phrenological studies conducted by Dr. Franz Joseph Gall discredited in the nineteenth century. Phrenology was a popular pseudomedicine in the late 19th century that posited measurements and other characteristics of the human skull determined different aspects of a person's actions and personality.

Answer A is correct.

Phrenology was mostly discredited as a scientific theory by the 1840s. This was due only in part to a growing amount of evidence against phrenology. Phrenologists had never been able to agree on the most basic mental organ numbers, going from 27 to over 40, and had difficulty locating the mental organs.

Gall believed that bumps on the surface of the brain could be detected by feeling the bumps on the surface of an individual's head. 1 He suggested that the bumps, indentations, and overall shape of the skull could be linked to different aspects of a person's personality, character, and abilities.

Most of the confirmed hypotheses found to be fabricated were the phrenological studies conducted by Dr. Franz Joseph Gall discredited in the nineteenth century. Phrenology was a popular pseudomedicine in the late 19th century that posited measurements and other characteristics of the human skull determined different aspects of a person's actions and personality.

By the 1840s, phrenology had lost much of its credibility as a scientific hypothesis. This was only partially caused by mounting evidence that refuted phrenology. [40] Phrenologists struggled to locate the mental organs and were never able to agree on even the most basic mental organ counts, which ranged from 27 to over 40. Organ placement was determined by phrenologists using cranioscopic readings of the skull. According to research performed by Jean Pierre Flourens on pigeon brains, the loss of some brain regions either had no effect on function or resulted in the loss of a function entirely unrelated to that which phrenology had assigned to that region. Although not flawless, Flourens' experiment appeared to show that Gall's purported organs were fictitious.

Since phrenology was used by businesspeople to abuse the middle and working classes, scientists had also lost faith in it. The popularisation of phrenology led to its simplicity and the incorporation of physiognomic principles, which Gall had initially dismissed as a personality predictor. From the beginning, phrenology was tarnished by claims that it promoted materialism and atheism and undermined morals. All of them contributed to the demise of phrenology. Recent research have further debunked phrenology claims utilising cutting-edge technologies like magnetic resonance imaging.

Explanation:

Plastic is defined as a material that contains an essential ingredient an organic substance of large molecular weight. It is also defined as polymers of long carbon chains. Carbon atoms are linked in chains and are produced in long-chain molecules.

Answer:

Plastic is a synthetic or semi-synthetic polymer material that is commonly used in the manufacturing of a wide range of products due to its versatility and durability. It is made up of long chains of molecules called polymers, which are formed by chemically bonding individual monomers (basic building blocks) together.

Plastic can be molded or shaped into various forms and can be made in a wide range of colors and textures. It is lightweight, strong, and relatively inexpensive to produce, which makes it ideal for use in many applications. Plastic can be found in everyday items such as water bottles, food containers, toys, electronic devices, and many other products.

While plastic has many advantages, it also poses significant environmental challenges. Plastic waste takes hundreds of years to break down and can accumulate in the environment, polluting waterways and harming wildlife. Some types of plastic also contain harmful chemicals that can leach into the environment and pose a risk to human health.

To address these challenges, there is growing interest in developing more sustainable alternatives to traditional plastic, such as biodegradable plastics made from renewable materials, as well as efforts to reduce plastic waste through recycling and other strategies.

The immune system is the body’s natural defense against pathogens, infections, and other foreign substances that may enter the body. It is made up of a complex network of organs, tissues, and cells that work together to protect the body from disease and infection.

The immune system is constantly on alert, ready to attack any outside invaders. It produces antibodies that bind to and destroy foreign invaders and helps the body to recognize and respond to infection. The immune system is also responsible for identifying and destroying cancer cells, as well as helping to regulate the body’s inflammatory response.

The comma-shaped structure lying over the testes, which stores sperm cells while they mature, is called epididymis.

The epididymis is a convoluted, flattened structure that is wrapped around the posterior aspect of the testis. It connects to the vas deferens, which is a tube that connects the epididymis to the urethra. The epididymis is where the sperm matures and gains the ability to swim. It plays a significant role in the reproductive process because it stores and transports sperm cells.

Sperm cells can be stored in the epididymis for weeks or even months while they mature. Sperm that aren't ejaculated during sexual intercourse are reabsorbed by the body. Any sperm that stays in the epididymis for an extended period may become damaged or die, reducing fertility. As a result, it's critical to maintain healthy habits and ensure that sperm are ejaculated regularly to keep the epididymis healthy.

Natural selection is the process by which organisms that possess certain traits are more likely to survive and reproduce than those without the traits.

This process is responsible for the gradual evolution of species and is one of the most important mechanisms of evolutionary change. In order for natural selection to occur, several key factors must be present, including variation within a population, inheritance of traits, selective pressure, and genetic differences.

The factor that is not required for natural selection to occur is an anticipated change in the environment. While environmental changes can certainly influence the process of natural selection, they are not a necessary component. For example, if a population has sufficient variation and is subject to strong selective pressures, natural selection can still occur even if the environment remains constant. Therefore, while environmental change can be an important factor in the process of natural selection, it is not a requirement for natural selection to occur.

In conclusion, for natural selection to occur, several key factors must be present, including variation within a population, inheritance of traits, selective pressure, and genetic differences. An anticipated change in the environment is not required for natural selection to occur, although it can certainly influence the process. By understanding the components of natural selection, we can gain a better appreciation for the process by which species evolve and adapt to their environment.

Answer:

glucose

Explanation:

most of the reaction comes from the mitochondria which produces glucose for the cells.

The correct statement is "individuals do not evolve, populations do evolve."

Evolution is a process that occurs over generations, and it involves changes in the genetic makeup of populations. Individuals cannot evolve because their genes remain constant throughout their lifetime. However, populations evolve as the frequency of certain genes changes within the group, either due to natural selection, genetic drift, gene flow, or mutation.

These changes ultimately lead to the development of new traits, adaptations, and sometimes, the emergence of new species.

While individuals themselves do not evolve, their genetic makeup contributes to the evolutionary process that occurs at the population level over generations.

Explanation:

Reproduction in sea turtles, sea snakes, and marine iguanas all have some similarities, but also have some distinct differences.

Sea turtles, sea snakes, and marine iguanas all lay eggs. The female will lay eggs on a beach, or in a nest that she has dug out.

After the eggs are laid, the nest is then covered up and the female will leave.

The eggs then incubate on their own until they hatch.

The biggest difference in their reproduction is the way in which their eggs are incubated.

Sea turtles bury their eggs in the sand and rely on the warmth of the sun to incubate them.

Sea snakes lay their eggs on land and rely on the heat of the ground and the sun to incubate them. Marine iguanas rely on the constant warmth of the lava rocks on the beach to incubate their eggs.

The mating process of these three animals also differs.

Sea turtles mate in the ocean and the male turtles will compete for a female’s attention. Sea snakes also mate in the ocean and the males will fight for the female’s attention.

Marine iguanas, on the other hand, mate on land and the males will fight for the female’s attention.

Overall, sea turtles, sea snakes, and marine iguanas have some similarities in their reproduction, but also have some distinct differences.

From the way in which their eggs are incubated, to the amount of eggs they lay, to the way that they mate, these animals have unique and fascinating reproductive cycles.

In second case, the blood must pass through axillary artery and brachial artery to enter ulnar artery.In third case, the blood must pass through external iliac vein to enter the inferior vena cava.In fourth case, the blood must pass through aortic arch to enter the left upper extremity. In fifth case, the blood must pass through popliteal vein to enter external iliac vein.

To move from the femoral artery to the posterior tibial artery, blood must pass through the following vessels: popliteal artery, which branches off the femoral artery, and then it further branches into the anterior and posterior tibial arteries.
To move from the subclavian artery to the ulnar artery, blood must pass through these vessels: axillary artery, brachial artery, and then it branches into the radial and ulnar arteries.To move from the femoral vein to the inferior vena cava, blood must pass through the external iliac vein, which then joins with the internal iliac vein to form the common iliac vein. The left and right common iliac veins then join to form the inferior vena cava. To move from the ascending aorta to the left upper extremity, blood must pass through the aortic arch and then enter the left subclavian artery, which supplies blood to the left upper extremity. To move from the anterior tibial vein to the external iliac vein, blood must pass through the popliteal vein, femoral vein, and then the external iliac vein is a continuation of the femoral vein.
