Zooxanthellae are modern corals that have a symbiotic relationship with dinoflagellates.

The dinoflagellates belong to the genus Symbiodinium and are commonly referred to as zooxanthellae when they form a symbiotic association with corals. This relationship is crucial for the survival and growth of coral reefs. The corals provide a protected environment and necessary nutrients for the zooxanthellae, while the zooxanthellae photosynthesize and provide the corals with energy in the form of organic compounds.

This mutualistic relationship enables corals to thrive in nutrient-poor tropical waters and is responsible for the vibrant colors seen in coral reefs. The symbiotic relationship between corals and zooxanthellae is highly beneficial for both partners. The zooxanthellae provide corals with up to 90% of their energy needs through photosynthesis, producing sugars and other organic compounds.

Stratum Corneum This layer is composed of the many dead skin cells that you shed into the environment—as a result, these cells are found in dust throughout your home. This layer helps to repel water.

The cells of the skin layer that protects the body came from preexisting cells.

This is according to the cell theory which states that:

Cells can only arise from existing cells by a reproductive process known as cell division. Cells can divide by mitosis if they are vegetative cells or by meiosis if they are sex cells.

The daughter cells produced in meiosis are usually genetically and phenotypically different from their parent cells, unlike mitosis where the daughter cells are essentially the same as the parent cells both genotypically and phenotypically.

The cells of the skin are vegetative cells. Thus, they can only reproduce by mitosis. This is why individual skin cells share the same trait.

When answering questions, it is important to be factually accurate, professional, and friendly. One should be concise and avoid providing extraneous amounts of detail. It is also important to use relevant terms in the answer.

Here is an example answer to the question, "ASAP please cell division in 140 words":Cell division is a vital process that occurs in living organisms. It is necessary for growth, repair, and reproduction. There are two types of cell division, namely mitosis and meiosis.

Mitosis is the type of cell division that occurs in somatic cells and results in the production of two identical daughter cells. Meiosis is the type of cell division that occurs in reproductive cells and results in the production of four genetically diverse daughter cells.

Cell division consists of several stages, including interphase, prophase, metaphase, anaphase, and telophase. During interphase, the cell grows and replicates its DNA. During prophase, the DNA condenses into chromosomes,

and the nuclear membrane breaks down. During metaphase, the chromosomes align along the equator of the cell. During anaphase, the sister chromatids separate and move towards opposite poles of the cell.

During telophase, the nuclear membrane reforms, and the chromosomes decondense.

Answer:

a

Explanation:

Answer:

A.

Explanation:

some bacteria help fight off disease.

Phosphorus is not as common as nitrogen or carbon because it is locked up in the lithosphere and only released through geological processes, which can take a very long time.

Due to the fact that it does not exist as a gas, phosphorus is not as abundant as carbon. Leaching and runoff both contribute to the introduction of phosphorus into the ocean, where it dissolves in the water or enters marine food webs. Some phosphorus disperses to the ocean floor, where it forms silt. This sediment may drift back to the surface if uplift takes place.

The lithosphere and the geological process, which takes time, both finish the phosphorus cycle. When it weathers, it leaks out through water but is still held in the rocks. In this way, phosphorus from the soil and water is absorbed by the plants.

When the number of organisms increases in an ecosystem the competition for the resources present in the ecosystem increases. An ecosystem is a complex network of living and nonliving components that interact with each other to sustain life.

The living component of the ecosystem comprises of biotic components, which include all the organisms that inhabit the ecosystem.When the number of organisms increases in an ecosystem, it puts a strain on the resources present in the ecosystem. The availability of resources such as food, water, and space becomes scarce as more organisms compete for these resources.

This increased competition can have a significant impact on the overall health of the ecosystem, as organisms begin to struggle to survive.As a result of the increased competition, some organisms may be forced to migrate or die. In addition, the population of certain species may decline as they struggle to compete with other species for resources. This can lead to a decrease in biodiversity, which can have a cascading effect on the entire ecosystem.

The property of water that allows ice to form and stay at the surface of a pond as winter progresses is the formation of hydrogen bonds between water molecules, making water cohesive.

This is option B in the question. As the temperature drops, the hydrogen bonds between water molecules become more stable, and the molecules spread out, causing water to become less dense. Eventually, the hydrogen bonds become stable enough to form a crystalline structure, creating ice. The cohesion of water molecules is also why ice floats on the surface of the water, rather than sinking to the bottom. This is important for aquatic life, as it allows a layer of unfrozen water to remain beneath the ice, providing a habitat for organisms to survive the winter.

Answer:

Metamorphosis is the process of transformation that insects undergo from egg to adult. There are two main types of metamorphosis: complete and incomplete. In both types of metamorphosis, the insect goes through a series of distinct stages, each with its own unique characteristics and functions.

Complete Metamorphosis:

Complete metamorphosis, also known as holometabolism, is a type of metamorphosis that involves four distinct stages: egg, larva, pupa, and adult. During complete metamorphosis, the insect undergoes a complete transformation in body form, function, and behavior.

Egg: The first stage of complete metamorphosis is the egg stage. The female insect lays eggs, which usually hatch within a few days or weeks, depending on the species.

Larva: The second stage of complete metamorphosis is the larval stage. The larva is the immature, worm-like stage of the insect. The larva is usually characterized by its voracious appetite, as it spends most of its time eating and growing.

Examples of insects that undergo complete metamorphosis include butterflies, moths, beetles, and flies.

Pupa: The third stage of complete metamorphosis is the pupal stage. During this stage, the larva undergoes a dramatic transformation, forming a protective cocoon or chrysalis around its body. Inside the cocoon or chrysalis, the insect's body undergoes extensive restructuring, including the formation of wings, legs, and other adult structures.

Adult: The final stage of complete metamorphosis is the adult stage. The adult insect emerges from its cocoon or chrysalis as a fully-formed, winged adult. The adult insect is usually sexually mature and is capable of reproducing.

Incomplete Metamorphosis:

Incomplete metamorphosis, also known as hemimetabolism, is a type of metamorphosis that involves three distinct stages: egg, nymph, and adult. During incomplete metamorphosis, the insect undergoes a partial transformation in body form, function, and behavior.

Egg: The first stage of incomplete metamorphosis is the egg stage, which is similar to that of complete metamorphosis.

Nymph: The second stage of incomplete metamorphosis is the nymph stage. The nymph is an immature stage of the insect that resembles the adult in many ways but lacks wings. Nymphs usually feed on the same food as adults and undergo several molts as they grow and develop.

Examples of insects that undergo incomplete metamorphosis include grasshoppers, cockroaches, and crickets.

Adult: The final stage of incomplete metamorphosis is the adult stage. The adult insect resembles the nymph but has fully formed wings and is sexually mature.

In summary, complete metamorphosis involves four stages: egg, larva, pupa, and adult, while incomplete metamorphosis involves three stages: egg, nymph, and adult. Examples of insects that undergo complete metamorphosis include butterflies, moths, beetles, and flies, while examples of insects that undergo incomplete metamorphosis include grasshoppers, cockroaches, and crickets.

Explanation:

Food chain describes the feeding pattern of a group of organisms in an ecosystem. The food chain shows how one organism in one TROPHIC LEVEL feeds on another organism in another. As organisms are being fed on, energy is being transferred.

A food chain always starts with a PRODUCER, which occupies the first and lowest trophic level. It creates the energy transfer as it obtains energy via photosynthetic process. The flow of energy as shown by an energy pyramid is Producer----First level consumer----Second level consumer------Third level consumer.

However, only about 10% of the available energy is transferred and accessible by the next organism. This is because about 90% of the energy has been lost as heat when the organism undergoes metabolic processes. Hence, if 1000 units of energy was present at the producer level, 10/100 × 1000= 100 units will be available to first level consumers.

Also, 10/100 × 100= 10 units of energy will be available to second level consumers and finally 10/100 × 10= 1 unit of energy will be available to talk third level consumer.
