Where is amyglada located in a brain ? How does it function ?​

Answers

Short Answer: The amygdala is located in the brain and its functions are related to emotional learning.

Explanation

The amygdala is a brain structure located in the temporal lobe of the brain. Its functions are related to the emotional system of the brain, and memory. In addition, the amygdala has been shown to influence the emotional learning process. The amygdala is mainly responsible for the formation and storage of memories associated with emotional events, so external sensory stimuli reach the basolateral group of the amygdala, where associations are formed with memories of the stimulus (mainly related to fear).

In humans, ventilation, digestion, and blood flow are important biological processes. Explain the relationship between the structure of tissues or organs and one of these processes.

Answers

Answer:

I am assuming the question is asking how do the processes relate to one another.

Explanation:

Ventilation happens in the lungs, where carbon dioxide and oxygen are exchanged in the alveoli. This is done via cappilaries that surround the alveoli. Cappilaries are small blood vessels, which are collecitelvy part of the blood flow system (circulation) of the body. In reguards to the digestion, there are capillaries in the vili (which are tiny finger-like structures) so that they can pick up the nutrients during digestion. Another way blood flow and digestion are connected is because the stomach is a muscle, thus is moves and requires energy. That energy comes from the oxygen and nutrients that is supplied by the blood. These are just some examples.

Why could the change in the tilt of Earth cause temperatures on
Earth to change?

Answers

The change in the tilt of the Earth can affect the distribution of sunlight and thus influence temperatures on Earth.

Earth's tilt and temperature

The tilt of the Earth, known as obliquity, affects the distribution of sunlight and influences temperatures.

A greater tilt leads to more pronounced seasons, with hotter summers and colder winters, while a lesser tilt reduces the seasonal contrast. These changes occur over long timescales.

However, short-term climate variations are primarily influenced by factors like greenhouse gases, ocean currents, and atmospheric circulation patterns.

how does the energy of the reactants and products differ between an energy absorbing reaction and an energy releasing reaction

Answers

In an energy absorbing reaction, the energy of the products is greater than the energy of the reactants. In an energy releasing reaction, the energy of the reactants is greater than the energy of the products.

The mass of the products is larger than the concentration of the reactants in an energy absorption process.

The power of the reaction mixture is larger than the radiation of the outputs in an energy-releasing process.

As substances disrupt bonds, energy released, and then when outputs make new bonds, release energy

Exothermic processes release energy, whereas endothermic reactions consume it. There is no general change in the quantity of energy throughout a chemical process, whether it collects or releases it.

Diane Dodd raised different fruit fly populations on different food sources. She found that after about 40 generations the evolution of reproductive isolation was under way. The mechanism of evolution responsible for this was Group of answer choices

Answers

Answer:

Natural selection.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

In this scenario, the mechanism of evolution responsible for this was natural selection because after about 40 generations the evolution of reproductive isolation was under way for the fruit fly. Thus, the more the offsprings that are reproduced by the parent organism, the more likely are they to survive.

Additionally, there is a better chance of having good or beneficial traits being passed from the parent organism to her offsprings.

do you think that the life of elderly people suffering from diabetes mellitus should be extended by giving them artificially produced insulin​

Answers

Explanation:

The prevalence of type 2 diabetes is increasing among older adults as is their diabetes-related mortality rate. Studies suggest that tighter glucose control reduces complications in elderly patients. However, too low a glycosylated hemoglobin (HbA1c) value is associated with increased hypoglycemia. Moreover, the appropriateness of most clinical trial data and standards of care related to diabetes management in elderly patients is questionable given their heterogeneity. Having guidelines to safely achieve glycemic control in elderly patients is crucial. One of the biggest challenges in achieving tighter control is predicting when peak insulin action will occur. The clinician’s options have increased with new insulin analogs that physiologically match the insulin peaks of the normal glycemic state, enabling patients to achieve the tighter diabetes control in a potentially safer way. We discuss the function of insulin in managing diabetes and how the new insulin analogs modify that state. We offer some practical considerations for individualizing treatment for elderly patients with diabetes, including how to incorporate these agents into current regimens using several methods to help match carbohydrate intake with insulin requirements. Summarizing guidelines that focus on elderly patients hopefully will help reduce crises and complications in this growing segment of the population.

Answer: Because Daltons theory states all atoms of a given element are identical in mass and properties.

Explanation:

The discovery of isotopes demonstrated that atoms of the same element can have different atomic weights, implying that atoms of the same element are not identical in every way. 

What is Dalton's atomic theory?

Dalton's atomic theory postulated that matter is made up of indivisible particles known as atoms, and that atoms of the same element are all identical and cannot be created or destroyed.

Compounds are formed by the simple combination of atoms into compound atoms.

Dalton, John Experiments with gases became possible at the turn of the nineteenth century, prompting John Dalton to propose a modern theory of the atom based on certain assumptions.

Dalton's theory is debunked. This is because Dalton's theory states that all matter is made up of identical, indivisible, and indestructible atoms. Isotopes have the same element but a different number of neutrons.

Thus, this way, the discovery of isotopes disprove one part of Dalton's atomic theory.

Explanation:

Ribose (otherwise known as D-ribose) is a sugar found in RNA (ribonucleic acid). It alternates with phosphate groups to create the “backbone” of the RNA polymer.

Deoxyribose (sugar in DNA) is one of the three components of nucleotides for DNA. Each nucleotide consists of a phosphate group and a nitrogenous base:  adenine, thymine, cytosine, guanine, and deoxyribose.

Glucose is a type of sugar which is a common and crucial energy source in living organisms and is often a component in various carbohydrates. Plants can create glucose by going through a process called photosynthesis, and once it's done with the process, they use the glucose (sugar) as their food for energy.

What are australopiths, how many groups are there, and what do they date to? Which one is derived and therefore not part of our direct evolutionary line?

Answers

Answer and Explanation:

Australopithecines were a group of ancestral animals that were very similar to chimpanzees, but had common characteristics with humans, which is something normal, when we think that these animals are one of the ancestors of human beings. These animals walked on two legs, like humans, but they had very small brains and teeth that were bigger and heavier than those of humans. There were eight groups of australopithecines and they date from 8 million to 1.5 million years ago.

Among these groups, it is believed that Australopithecus afarensis is a group that has no direct ancestry with humans, being a group that did not thrive during the evolutionary process.

In the early days of life on Earth, plants were exposed to extremely high doses of ultraviolet radiation. Constant UV exposure resulted in some land plants developing narrow leaves with thick, waxy cuticles. Over many, many generations, these narrow leaves evolved into needles.

Chemical hazards are non-biological substances that can cause damage to health. These are used in different enterprises, companies, school, universities and laboratories for different purposes such as cleaning, disinfection, scientific experiments, among others. When handling them, employees are exposed to them and are vulnerable to harm from these chemicals.  

There are many types of hazardous chemicals to be wary of, such as:

Carcinogens NeurotoxinsAcids Systemic toxins Asmogens Silica dust Lead

In the workplace, exposure to these substances represents a real occupational hazard and there must be regulations to ensure that they are safe to handle.

The Occupational Safety and Health Administration (OSHA) is the agency of the U.S. Department of Labor which determined the Hazard Communication Standards. This is a document with the necessary information to study the hazards of the chemical substances used by different employees in the companies, so that they are aware of the dangers of these substances. These employees have the right to know exactly what compounds they handle and the risks involved in their use as well as the precautions and care to be taken.
