Answer:

Naming binary (two-element) covalent compounds is similar to naming simple ionic compounds. The first element in the formula is simply listed using the name of the element. The second element is named by taking the stem of the element name and adding the suffix

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.

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.

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.

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.

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.

Therefore, the element that is most important for adding strength to hair, feathers, and outer skin is sulfur.

Answer:

B. The maximum

If you ever need to remember it, just know that capacity means the most.

Explanation:

Answer:

B

Explanation:

The carrying capacity is the max population an environment can support.

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

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.

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.

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.

Producers, consumers and decomposers are found nearly all ecosytems.

An ecosystem is a region where different species of plants, animals, and other organisms coexist in harmony with the environment, including the climate and geography.

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.
