An ecosystem experiences a volcanic eruption that covers the area with lava. Organisms moss is most likely to be a pioneer species in this ecosystem.
What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes.

Which element is most important for adding strength to hair, feathers, and outer skin? oxygen hydrogen sulfur phosphorus
Sulfur can help saturate the skin and kill the bacteria that cause skin irritation. For a long time, the most popular therapy for skin eruptions was the repulsive mineral once known as brimstone, hence option C is correct.
How sulfur provides strength to hair, feathers, and outer skin?Sulfur may kill skin cells and spread microscopic organisms, although it is not suitable for everyone. There is one skin type in particular that responds favorably to sulfur froths.
Vertebrates include the keratin type known as alpha-keratin (-keratin). In vertebrates, it is the primary structural component of their scales, hair, nails, feathers, horns, claws, hooves, and outer layer of skin. Epithelial cells are additionally shielded by keratin from harm or stress.
Therefore, sulfur can help saturate the skin and kill the bacteria that cause skin irritation, hence option C is correct.

The element that is most important for adding strength to hair, feathers, and outer skin is sulfur. Therefore, the correct statement is option C.
What are the advantages of sulfur?Sulfur-containing amino acids are the building blocks of keratin, which is a fibrous protein giving strength and structure to these tissues. Keratin is also found in nails, hooves, and scales of animals.
Sulfur creates a for adding strength to hair, feathers, and outer skin. Sulfur is a component of keratin and forms disulfide bonds with other sulfur molecules in the keratin, thereby, creating a strong structure that contributes to the strength of hair, feathers, and outer skin.
Without sulfur, these structures will be more prone to damage and breakage. The presence of sulfur is important for the proper formation of keratin and gives strength to hair, feathers, and outer skin.

Answer:
This child has learned to act from its adults.
Explanation:
This child has learned to act according to the reaction of the adult. If a child done something wrong and the adult reaction is not good the child will not repeat it because he knows that this act is bad while on the other hand, when the child done something good and the adult gives a good reaction so the child will continue doing this action so we can say that a child learn most of the things from their adults.

2. What is the relationship between air temperature and air pressure at the
equator?
Answer:
Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.
the pressure patterns associated with global circulation patterns. On the equator areas, since air is heated and rises, a zone of lower pressure will result.
Explanation:
mark it as brainliest. thnku hope it is helpful.
Explanation:
at the equator the air is moist and hot and when air is hot it's density decreases and so does the pressure exerted by it. and also air that contains water vapour is less denser than the air containing no or less water vapour so air containing less water vapour exerts more pressure

What does a single-celled prokaryote, like a bacteria, have in common with a single-celled eukaryote, like an amoeba? Select the correct answer.
Answer: Both are single-celled microorganisms which contains plasma membranes, cytoplasm, ribosomes, DNA
Explanation:
Cells are the smallest functional unit of organisms which are classified under two main categories namely:
--> prokaryotic cells and
--> eukaryotic cells.
Prokaryotes are unicellular or single-celled organisms which do not possess true nuclei. Their cell structure is simple as there is NO definite nucleus and the chromosomes lie free in a particular part of the cell. Examples of organisms that belongs to this group are the bacteria. They can only be seen through a high power of a light microscope and are found in air, water, soil and living organisms. The general structure of prokaryotes like bacteria contains Chromosome ( single DNA strand coiled up), cytoplasm, ribosome which are few cell components among others.
Eukaryotes are organisms which possess a definite or true nuclei. The cell structure is complex and highly organized with a well-defined nucleus (meaning its DNA is surrounded by a membrane). Many structures called the cell organelles are present which include: mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes with other cell components, that is the cytoplasm, plasma membrane and ribosomes. Each organelle carries out a certain type of work. Examples of organisms that belongs to this group are the amoebas.
From the explanation above, both bacteria and amoeba are single- celled organisms which contains plasma membranes, cytoplasm, ribosomes, and DNA.

Materials that have high resistance to electric current are called electric insulators. Examples include most nonmetallic solids, such as wood, rubber, and plastic. Their atoms hold onto their electrons tightly, so electric current cannot flow freely through them.
Can somebody please do 10 through 13 for me please:)
Answer:
10. Human Activity
Human activities emit 60 or more times the amount of carbon dioxide released by volcanoes each year.
11. Cooling Effect
When volcanoes erupt, they emit a mixture of gases and particles into the air. Some of them, such as ash and sulphur dioxide, have a cooling effect, because they reflect sunlight away from the earth. Others, such as CO2, cause warming by adding to the the greenhouse effect.
12.
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
13.
Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. ... But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.

what are 5 functions of carbohydrates
☁️ Answer ☁️
PROVIDES INSTANT ENERGY TO THE BODY:
This appears to be the primary function of carbohydrates in the body.
Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.
RESERVE FOOD:
Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
CARBOHYDRATES FORM OTHER BIOMOLECULES:
Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.
DETOXIFICATION OF THE BODY BY METABOLISM:
Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.
SPARING PROTEIN
In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors.
Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors. Along with rocks, temperature and humidity are abiotic variables.
Every component of an ecosystem is directly or indirectly dependent upon every other component.
