Answer:
When carbon dioxide dissolves in seawater, the water becomes more acidic and the ocean’s pH (a measure of how acidic or basic the ocean is) drops. Even though the ocean is immense, enough carbon dioxide can have a major impact. In the past 200 years alone, ocean water has become 30 percent more acidic, faster than any known change in ocean chemistry in the last 50 million years.

Below is the base sequence on one side of a DNA molecule. What would the complimentary side of this strand of DNA read? ATC TCA GAT CGT CAG
UAG AGA GUA CGA GUC
AUC UCA GAU CGU CAG
ATC TCA GAT CGT CAG
TAG AGT CTA GCA GTC
The complimentary side of this strand of DNA would read: TAG AGT CTA GCA GTC.
What is complementary strand?The complementary strand is a term used to describe the second strand of DNA in a double-stranded DNA molecule. The two strands of DNA run in opposite directions and are held together by hydrogen bonds between complementary base pairs, which are adenine (A) and thymine (T), and cytosine (C) and guanine (G).
The complementary nature of the two DNA strands allows for accurate duplication of genetic information when the cell divides. In addition, the complementary strand can serve as a template for the production of messenger RNA (mRNA), which is used to direct the synthesis of proteins. The complementary strand is therefore an essential component of DNA structure and function.

1.What is unique about the reflex behavior?
The messages never reach the central nervous system
It originates in the spinal cord, not the brain
It is localized in the cerebellum instead of the cortex
It only uses the autonomic nervous system
2.The peripheral nervous system is made up of:
The sympathetic and parasympathetic systems
The autonomic and somatic systems
The environment and sensory receptors
The brain and spinal cord
3.Which of the following behavior would be associated with the SOMATIC nervous system?
Breathing during sleep
Heartbeat
Scratching an itch on your head
Sweating
4.In regards to the Autonomic nervous system, Sympathetic is to Parasympathetic as:
Automatic Behaviors: Voluntary Behaviors
Calms you down; Reacts to threat
Voluntary Behaviors
Reacts to a threat; Calms you down
5.Sensory nerves that carry information from the environment and bring it back to the the Central Nervous System are part of the
Sympathetic Nervous System
Parasympathetic Nervous System
Somatic Nervous System
Autonomic Nervous System
Answer:
The thing that is unique about the reflex of behavior is it is involuntary and almost instantaneous reaction to a stimulus. Take plants for an example. Their stimuluses are tropisms. Phototropism is a reaction to a light source in order to achieve photosynthesis. Hydrotropism is a plant's reaction to a nearby water source, in which the plant's roots grow towards it. Geotropism is a plant's reaction to gravity, in which the plant's roots grow down, and the stem grows up.
The peripheral nervous system is made up of The brain and spinal cord.
The behavior that would be associated with the SOMATIC nervous system is scratching an itch on your head.
In regards to the autonomic nervous system, sympathetic is to parasympathetic as calms you down; reacts to threat.
Sensory nerves that carry information from the environment and bring it back to the central nervous system are part of the autonomic nervous system.

1. Decribe the similarities and differences between the endocryme and nervous regulation?
2. The pancreas and the gonads are glands with double secreation. Explain why.
3. Patiens suffering from the disease diabetes mellitus have increased level of blood sugar. Why hormone is insufficent and what it the functions of this hormone?
Answer:
1. Describe the similarities and differences between endocrine and nervous regulation?
All neurons have several features in common, including a cell body, dendrites, and an axon. These structures are important for transmitting neural impulses, electrical signals that allow neurons to communicate with one another.
Neurons are specialized, depending on their required functions:
Sensory neurons carry impulses from sense organs, such as the eyes or ears.
Motor neurons carry impulses to muscles and glands.
Interneurons transfer signals between sensory and motor neurons, as well as in between other interneurons.
In a resting neuron, there is a separation of ions in the cell regulated by sodium-potassium pumps. If a neuron receives a large enough signal, the resting potential changes, producing an electrical impulse called an action potential. Once an impulse begins, it moves down the axon until it reaches the axon terminal.
2. The pancreas and the gonads are glands with double secretion. Explain why. Endocrine organs are ductless organs of the endocrine framework that emit their items, chemicals, straightforwardly into the blood. The significant organs of the endocrine framework incorporate the pineal organ, pituitary organ, pancreas, ovaries, testicles, thyroid organ, parathyroid organ, nerve center, and adrenal organs. The nerve center and pituitary organs are neuroendocrine organs.
3. Patients suffering from the disease diabetes mellitus have an increased level of blood sugar. Why hormone is insufficient and what it the functions of this hormone?
Diabetes mellitus is a condition in which the body does not produce enough of the hormone insulin, resulting in high levels of sugar in the bloodstream. There are many different types of diabetes; the most common are type 1 and type 2 diabetes, which is covered in this article. Gestational diabetes occurs during the second half of pregnancy and is covered in a separate article. Diabetes can also be caused by disease or damage to the pancreas, Cushing's syndrome, acromegaly, and there are also some rare genetic forms.
Diabetes mellitus is linked with an increased risk of heart attacks, strokes, poor blood circulation to the legs, and damage to the eyes, feet, and kidneys. Early diagnosis and strict control of blood sugar, blood pressure, and cholesterol levels can help to prevent or delay these complications associated with diabetes. Maintaining a healthy lifestyle (regular exercise, eating healthily, and maintaining a healthy weight) is important in reducing the risk of developing type 2 diabetes.
Diabetes can be looked for by testing a urine sample for sugar but for a diagnosis, a blood sample is required. This may be a simple measurement of the sugar level, usually fasting. Alternatively, a test called an HbA1c can be used which estimates sugar levels over the past couple of months. If someone has typical symptoms of diabetes, only a single abnormal test is required. Where there are no symptoms, a second confirmatory test is required. Sometimes, particularly in pregnancy, a glucose tolerance test is performed which involves blood tests before and 2 hours after a sugary drink.
Insulin is a hormone produced in the pancreas by special cells, called beta cells. The pancreas is below and behind the stomach. Insulin is needed to move blood sugar (glucose) into cells. Inside the cells, glucose is stored and later used for energy.
When you have type 2 diabetes, your fat, liver, and muscle cells do not respond correctly to insulin. This is called insulin resistance. As a result, blood sugar does not get into these cells to be stored for energy.
When sugar cannot enter cells, a high level of sugar builds up in the blood. This is called hyperglycemia. The body is unable to use the glucose for energy. This leads to the symptoms of type 2 diabetes.
Type 2 diabetes usually develops slowly over time. Most people with the disease are overweight or obese when they are diagnosed. Increased fat makes it harder for your body to use insulin the correct way.
Type 2 diabetes can also develop in people who are not overweight or obese. This is more common in older adults.
Family history and genes play a role in type 2 diabetes. Low activity level, poor diet, and excess body weight around the waist increase your chance of getting the disease.
