Phytoplankton are tiny plants that drift with the currents of the ocean and they are organisms that support all other life in the oceans.
What are the features of phytoplankton?Phytoplankton are the autotrophic components of the plankton community and a key part of ocean and freshwater ecosystems.
Moreover, phytoplankton offers a broad spectrum of minerals that come from the sea – magnesium, phosphorus, potassium, calcium, iron and zinc.
Phytoplankton are microscopic plants, but they play a huge role in the marine food web. Like plants on land, phytoplankton perform photosynthesis to convert the sun's rays into energy to support them.

Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.
(PLEASE HELPPPP 90 POINTS!!)
Which best describes the next step in the formation of metamorphic rocks?
Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.
Answers
The correct answer is B. When buried rocks are forced toward the mantle, they undergo extreme heating and pressure, which can cause them to melt. This molten rock is known as magma, which then crystallizes as new minerals as the magma cools and solidifies. This process is known as metamorphosis and is the second step in the formation of metamorphic rocks.
Buried rocks melt deep within the mantle.

Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

What type of response occurs when you watch someone eating a lemon and your face puckers?
external response
sour response
internal response
lemon response
Answers
Answer:
The type of response that occurs when you watch someone eating a lemon and your face puckers is an external response. An external response is a physical reaction that is visible to others and occurs in response to a stimulus, in this case, the sight of someone eating a lemon. It is also sometimes called a behavioral response.
An internal response, on the other hand, is a response that occurs inside the body and is not visible to others. For example, when you eat a lemon, you may experience an internal response such as an increased production of saliva in your mouth or a sour taste in your mouth.
A sour response is a type of internal response that refers specifically to the taste of something that is sour, such as a lemon.
A lemon response is not a commonly used term in psychology or physiology. It could refer to any type of response that is related to lemons, such as the external response of puckering your face or the internal response of experiencing a sour taste.

Is Solid waste point source pollution or non point source pollution?
Answers
Answer:
Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.
In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.
Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

Explain the asthma disorder.
Answers
The exact causes of asthma are not fully understood, but it is believed to be a combination of genetic and environmental factors. Asthma triggers can vary from person to person, but some common triggers include:
Allergens such as dust mites, pollen, and pet dander
Irritants such as smoke, air pollution, and strong odors
Exercise and physical activity
Respiratory infections such as colds and flu
Symptoms of asthma can include:
Wheezing: a whistling sound when breathing
Coughing, especially at night or early in the morning
Shortness of breath or difficulty breathing
Chest tightness or pain
Asthma is typically diagnosed based on a combination of symptoms, medical history, and lung function tests such as spirometry. Treatment for asthma often includes medications such as inhaled corticosteroids and bronchodilators, which can help reduce inflammation and open up the airways. It is also important for people with asthma to avoid triggers as much as possible and to have an asthma action plan in place to help manage symptoms and prevent asthma attacks. In severe cases, hospitalization may be necessary.
Mark brainliest pls
Asthma is a chronic respiratory disorder that affects millions of people worldwide. It is a condition that causes the airways in the lungs to become inflamed, making it difficult to breathe. This inflammation can also cause the airways to become more sensitive to certain triggers, such as allergens, pollutants, and exercise.
The symptoms of asthma can vary in severity from person to person, but they typically include wheezing, coughing, chest tightness, and shortness of breath. These symptoms can be triggered by a variety of factors, including exposure to allergens such as dust mites, pollen, and pet dander; irritants such as cigarette smoke and air pollution; respiratory infections; exercise; and emotional stress.
Asthma can be classified as either intermittent or persistent, depending on the frequency and severity of symptoms. Intermittent asthma is characterized by infrequent and mild symptoms, while persistent asthma is characterized by frequent and severe symptoms that can affect a person's daily activities and quality of life.
Asthma is typically diagnosed through a combination of medical history, physical examination, and lung function tests. Treatment for asthma usually involves a combination of medications and lifestyle changes, such as avoiding triggers and improving overall health through regular exercise and a healthy diet.
Medications used to treat asthma include inhaled bronchodilators, which relax the muscles around the airways and allow them to open up, and inhaled corticosteroids, which reduce inflammation in the airways. In more severe cases, oral medications or injections may be necessary.
In addition to medication, lifestyle changes can also play an important role in managing asthma. For example, avoiding triggers such as allergens and pollutants, maintaining a healthy weight, and staying physically active can all help to improve asthma symptoms and overall lung function.
Overall, asthma is a complex and challenging disorder that requires ongoing management and attention. However, with proper treatment and care, most people with asthma are able to lead full and active lives, free from the limitations and symptoms of this condition.
