What is psychoanalytic theory?The psychoanalytic theory is the theory that teaches that the behaviour of an individual depends on their past experiences.
The two main psychologist that developed the psychoanalytic theory are Sigmund Freud and Erick Erickson.
The similarity between the psychoanalytic theories of Freud and Erikson is that they both separate development into stages of a individual's life.
The difference between the psychoanalytic theories of Freud and Erikson is that Sigmund Freud focused on the influence of the basic needs and biological forces while Erick Erickson focused on the social and environmental factors.
Erikson’s theory explain the different stages of adulthood from the age of 18 to 40 years as intimacy versus isolation.

Which best describes the activity of autotrophs?
a.They use the energy harvested by, other photosynthesizers.
b. They use the energy harvested by heterotrophs.
c. They convert carbon dioxide and water, with the assistance of light into complex, energy-rich organic molecules, such as glucse.
d. They use sunlight to break down large complex, energy-rich organic molecules, such as glucose.
Answer:
I would go to option C
Explanation:
Autotrophs are organisms that can produce their own food, using materials from inorganic sources. Option C matches this definition and process.
Stay safe and Merry Christmas! :)
The correct answer about the activity of autotrophs is - c. They convert carbon dioxide and water, with the assistance of light into complex, energy-rich organic molecules, such as glucose.
Autotrophs are the organisms that make their food and produce energy on their own. These organisms are not dependable on any other organisms.
These organisms produce their food and energy mostly by the process called photosynthesis.They convert carbon dioxide and water into energy-rich organic molecules, known as glucose.this process takes place in the presence of sunlight.Thus, the correct answer is - option C.

Describe the physiological process of hunger. Include a discussion about glucose, the hypothalamus, set point, ghrelin/leptin, and basal metabolic rate in your response. Then, describe the cultural and situational factors that influence hunger.
Answer:
Ghrelin is made in the stomach. It stimulates hunger by entering the brain and acting on the neurons in the hypothalamus to increase the activity of the hunger-causing nerve cells and reducing the activity of hunger-inhibiting cells. As the stomach empties, the release of ghrelin increases. Leptin is a protein produced by fat cells that is a hormone acting mainly in the regulation of appetite and fat storage. When your blood sugar levels are too low, your cells become starved for energy. At first, you might notice minor symptoms, such as hunger and headaches. However, if you don’t get your blood sugar levels up in time, you may be at risk for serious complications. Introducing more glucose into your body will help solve the problem of low blood sugar. Our hunger is influenced not only by our physical state but also by our memory of when we last ate and our expectation of when we should eat again, this is what the hypothalamus does. According to set point theory, after a time, your body will fight reduced calorie intake by sending signals (hunger indications) and slowing down your metabolism to attempt to bring you back to your normal set point. Basal Metabolic Rate is the number of calories required to keep your body functioning at rest. BMR is also known as your body's metabolism; therefore, any increase to your metabolic weight, such as exercise, will increase your BMR. Everyone's basal metabolic rate is different. Although we humans as a species prefer certain tastes (such as sweet and salty), we learn to satisfy those preferences with specific foods eaten in the context of our families and our culture. Some of our taste preferences, such as the avoidance of new foods or of foods that have made us ill, have survival value.

Ghrelin is made in the stomach. It stimulates hunger by entering the brain and acting on the neurons in the hypothalamus to increase the activity of the hunger-causing nerve cells and reducing the activity of hunger-inhibiting cells.
Which cells are responsible for hunger?
Ghrelin is a multifaceted gut hormone which activates its receptor, growth hormone secretagogue receptor (GHS-R). Ghrelin's hallmark functions are its stimulatory effects on food intake, fat deposition and growth hormone release. Ghrelin is famously known as the “hunger hormone”.
Moreover, when food is scarce, some brain cells begin to devour themselves, activating an appetite-stimulating molecule in the process. A brain region called the hypothalamus contains neurons that regulate feeding in response to nutritional signals.
Therefore, within the hypothalamus are nerve cells that, when activated, produce the sensation of hunger. They do so by producing two proteins that cause hunger: neuropeptide Y (NPY) and agouti-related peptide (AGRP). Quite close to these nerve cells is another set of nerves that powerfully inhibit hunger.

All plants are multicellular, All plants are eukaryotic, All plants are autotrophic, and All plants need sunlight.
All plants are multicellular, All plants are eukaryotic, All plants are autotrophic, and All plants need sunlight are true about plants.
What are the characteristics of autotrophs?An autotroph or primary producer is an organism that produces complex organic compounds using carbon from simple substances such as carbon dioxide, generally using energy from light or inorganic chemical reactions.
Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms. Algae, which live in water and whose larger forms are known as seaweed, is autotrophic.
Examples of organisms that are autotrophic are plants and algae, and they have specialized cell organelles that have the ability to power the process of photosynthesis.

5. Knowing that acid rain has a pH of 2-3, would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?
Answer:
Yes
Explanation:
Unless the crops acidity range is that of the rain( which it wouldn't be) it would throw off the crops Ph balance and harm it.
Yes, crop species with a narrow soil pH range are potentially in trouble due to acid rain. Acid rain can have harmful effects on plant growth and productivity. The acidity of the rain can change the pH level of the soil, making it more acidic and less hospitable for plants.
What is acid rain?Acid rain is a type of rain or other precipitation that is unusually acidic and has elevated levels of hydrogen ions (low pH). It is caused by the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which then reacts with water vapor to form sulfuric acid and nitric acid.
These acids can fall back to the ground as acid rain or other forms of precipitation and can cause harm to plants, animals, and infrastructure. Acid rain can also contribute to soil and water pollution and can have negative impacts on human health.
Acidic soil can also release toxic substances, such as aluminum, which can further damage plant roots and reduce plant growth. In addition, acid rain can damage plant foliage directly, leading to reduced photosynthesis and reduced yields.
So, acid rain can be a significant problem for plant species and crops, particularly those with a narrow soil pH range.
