Describe how
dehydration, ADH and thirst play a role in the feedback mechanism that controls water balance in the
human body.
Answer: Ok so this may be a little off but ill do my best
Explanation:
On a typical day, the average adult will take in about 2500 mL (almost 3 quarts) of aqueous fluids. Although most of the intake comes through the digestive tract, about 230 mL (8 ounces) per day is generated metabolically, in the last steps of aerobic respiration. Additionally, each day about the same volume (2500 mL) of water leaves the body by different routes; most of this lost water is removed as urine. The kidneys also can adjust blood volume though mechanisms that draw water out of the filtrate and urine. The kidneys can regulate water levels in the body; they conserve water if you are dehydrated, and they can make urine more dilute to expel excess water if necessary. Water is lost through the skin through evaporation from the skin surface without overt sweating and from air expelled from the lungs. This type of water loss is called insensible water loss because a person is usually unaware of it.ADH is a hormone in your body that helps your kidneys manage the amount of water in your body. Dehydration means you need water and when your thirsty your body wants water. So when your thirsty, your brain is letting you know you need water, and if you don't drink water you will become dehydrated and that can lead to kidney failure.
Your kidneys have a very important role of water management.

What is the acceleration of a 50 kg object pushed with a force of 500 newtons
Force is equal to mass times acceleration, therefore acc. is equal to Force divided by mass.
500 N /50kg equals 10m/s^2.
The acceleration of a 50 kg object pushed with a force of 500 Newtons is 10 m/s^2, calculated using Newton's second law of motion.
Explanation:To calculate the acceleration of an object, we use Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration (F = ma). If a 50 kg object is being pushed with a force of 500 Newtons, you would solve the equation for acceleration, a = F/m. Thus, a = 500N / 50kg = 10 m/s^2.

Analyze: Was the increase in the average beak depth caused by an increase in
large-beaked finches or a decline in small-beaked finches? Explain your answer.
Answer:
No
Explanation:
Charles Darwin went to the Galapagos island and found four different types of finch, he found out that all there beaks where different which allowed them to adapt to their environment. their beaks are for different things.
Answer:
I believe the increase in the average beak depth was caused by both the increase in large-beaked finches and a decline in small-beaked finches, since due to the disappearance of the small-beaked finches, only the long-beaked finches will be taken into consideration, so the average depth of the beak will be greater. The finches with small beak depth will not be counted.

D) methane decreased, leading to less energy in the earth system and less energy absorbed by Earth's surface.
PLEASE HELP ASAP!!
Answer:
i think its a
Explanation:
The correct answer is A: methane increased, leading to more energy in the earth system and more energy absorbed by Earth's surface. This is due to methane's effectiveness as a greenhouse gas that traps heat in the Earth's atmosphere.
The question deals with the effects of methane on the Earth's energy balance, specifically during a time period 3 billion years ago when less energy entered the Earth system than exited. As it pertains to the greenhouse effect, when the concentration of methane in the atmosphere increases, it leads to more energy being trapped within the Earth system. Methane is a potent greenhouse gas that absorbs and emits infrared radiation much more efficiently than carbon dioxide, contributing to an increase in the Earth's surface temperature because it traps more heat in the atmosphere.
Given this understanding, the correct option is A which states that an increase in methane leads to more energy in the earth system and more energy absorbed by Earth's surface. This is consistent with the function of greenhouse gases, notably their role in allowing sunlight to enter but impeding the escape of infrared radiation back into space, resulting in warming.

2. When you decrease the pH in the simulation, the ocean's acidity increases. What do you expect
to happen over time to the population of the corals, algae, and fish in the coral reef as the pH of
the ocean decreases?
Answer:
With decrease in pH of ocean water, the survival rate of corals, algae, and fish in coral reef reduces.
Explanation:
Coral reefs find difficulty in living in acidic ocean water. It is so because the coral’s shell that is made up of calcium carbonate is unable to sustain in acidic environment.
Not only this the skeleton of snails, clams, algae , fish etc is also made up of calcium carbonate. Increased acidity leads to death of these species.
Thus, the lower is the pH of ocean water, the higher is its acidity and hence the lower is the probability of survival of corals, algae, and fish in the coral reef
pH is among the limiting factors that might affect coral, algae and other species. A decrease in water pH causes an increase in acidity, which leads coral, algae, and fish in the coral reef to death.
What is the relationship between corals and algae?
Corals are translucid or white, but they look brightly colored because they host symbionts with colorful photosynthetic pigments . They can host different organisms that live on and among them, giving place to an amazing ecosystem.
One of these organisms is the photosynthetic unicellular microalgae, called zooxanteles. Corals provide shelter and protection to the algae, while algae provide nitrogenated nutrients, sugars, and color to the corals.
This symbiotic relationship allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as the tropical clear waters.
What are the limiting factors of corals and algae?Limiting factors are environmental conditions that act directly on populations and individuals, limiting their distribution and growth.
Some of these factors are water, temperature, pH, salinity, and radiation.
When changes in any of these factors occur, corals react to these changes losing these algae and becoming translucid again.
pH is a significant limiting factor for coral survival because their calcium-carbonated shell is sensitive to acidic environments.
When there is a decrease in oceanic pH, occurs an increase in water acidity, causing coral, algae, and other organisms death.

When muscles contract, they become____
The muscles of the rear end, legs, and feet are called____ muscles.
______ muscles move food down the
digestive tract.
The correct completions for the statements are as follows: When muscles contract, they become shorter and thicker. The muscles of the rear end, legs, and feet are called skeletal muscles. Smooth muscles move food down the digestive tract.
1. When muscles contract, they exert force on the structures they are attached to, which typically results in the muscles becoming shorter and thicker. This is due to the sliding filament mechanism where the myosin heads pull on the actin filaments, causing the filaments to slide past each other and shorten the muscle fiber.
2. The muscles of the rear end, legs, and feet are classified as skeletal muscles. These muscles are striated, under voluntary control, and attached to the skeleton by tendons. They are responsible for movement and posture.
3. Smooth muscles are responsible for moving food down the digestive tract. These muscles are involuntary and are found within the walls of internal organs such as the stomach, intestines, and blood vessels. They are called smooth because they lack the striated appearance of skeletal and cardiac muscles. The coordinated contractions of smooth muscles, known as peristalsis, propel food through the digestive system.
