Answer:
Dopamine is a substance produced in the brain and is responsible for controlling our movements. The cells that produce dopamine are located in an area known as the brainstem, from where dopamine is then secreted into the basal ganglia, an area of the brain that plays an important function in regulating our movements.

SOMEONE HELP PLEASE!! State how the digestive, respiratory, and circulatory systems are connected. State how food is eventually used by our cells by involving all systems.
Answer:
Our organ systems in the human body perform functions such as digesting food, breathing and transporting important nutrients for the human body to function properly. Thus, while the digestive system processes food, the respiratory system provides oxygen and the excretor eliminates waste, the circulatory system connects the different systems for the human body to function.
Explanation:
When we eat, we incorporate different nutrients that provide us with the substances and energy that our body needs to function properly. The digestive system allows us to obtain these nutrients, while the circulatory system is responsible for carrying them throughout the body. The nutrition function, which allows the use of nutrients, is carried out by the digestive, circulatory, respiratory and excretory systems. Food, once ingested, is subjected in the digestive system to crushing and chemical transformation (digestion) that results in obtaining simpler substances, converting them into soluble and assimilable substances (nutrients) that are incorporated into the circulatory system and are transported to each of the cells of the tissues. A proportion of the oxygen that is part of the inspired air and that has penetrated the lungs, enters the blood circulation in the pulmonary alveoli. In this way, oxygen enters the circulatory system to be transported to all cells in the body.

plsss help
Answer:
mineral is a phosphate
Explanation:
Answer:
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid H ₃PO ₄. The phosphate or orthophosphate ion [PO ₄]³⁻ is derived from phosphoric acid by the removal of three protons H⁺ .

1. Make a prediction of how self-control impacted the GPA of the students in the study and explain WHY you think so. 2. Then answer one of these questions: What helps you control yourself?
What makes you feel out of control?
What makes you fearful?
What helps you feel calm?
Answer:
Explanation:
1. A study conducted by Tangney, Baumeister, and Boone, indicates that self-control not only could predict GPA, but also better adjustment, better interpersonal, secure attachment, and more optimal emotional responses.
2. Start by slowing your thinking down. Take slow deep breaths. Take yourself to a quiet place. By learning how to recognize our inner emotions and thoughts, name them, and let them pass through us, we can practice more self-control, which also helps build greater agency.

What is the main source of Earth's light?
Answer:
The Sun
Explanation:
Answer:
The sun
Explanation:
The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things.

describe how you could determine the population size of a specific type of plant in a large forest without counting all of the plants
Answer:
The study of living and nonliving components of a system can be best described as an. ecosystem ... Describe how you could determine the population size of a specific type of plant in a large forest without counting all of the plants
It is possible to determine the population size of a specific plant in a forest by counting the number of the specific plant in a small section of the forest and then multiply this by the total area.
This technique is known as quadrat sampling.
Quadrat sampling is a methodology by which organisms of a sample of the habitat are directly counted and then this value is used to calculate the total population of an area, i.e., the total number of individuals/organisms in a given area.
In this case, a quadrat delimits a small area in which the specific plant can be estimated.
The abundance of a population in a particular area can be estimated by using the number found per quadrat and then multiply this value by the total size of the area.
Quadrat sampling is a very useful methodology for the study of biodiversity.
In conclusion, it is possible to determine the population size of a specific plant in a forest by counting the number of the specific plant in a small section of the forest and then multiply this by the total area.

Investigator Campbell is in charge of the forensics lab. One of the analysts in the lab ended up with contaminated evidence from the scene of an explosion. Looking through their work area, she sees they have a very small table next to a sink with small nylon bags stored in tight rows at room temperature. What would she advise the analyst to change about their evidence system? The evidence needs to be refrigerated quickly between analyses. The evidence can't be stored in nylon bags at all. The bags can't be kept so close together. They can’t be near the sink—it’s too humid.
Answer:
The bags can't be kept so close together.

How does DNA replication in prokaryotes differ from replication in eukaryotes?
Prokaryotic chromosomes have telomeres, and eukaryotic chromosomes do not.
Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have many.
The prokaryotic DNA had multiple parts to be replicated, compared to one long chromosome in eukaryotes.
The rate of elongation during replication is slower in prokaryotes than in eukaryotes.
Answer:
Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have many.
Explanation:
If eukaryotic chromosomes did not have many origins of replications then replication would take insanely long due to how much longer eukaryotic genes are!
