Answer:
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
Most of the ocean floor is a type of rock called basalt. At the edge of continents, this basalt erodes and becomes small particles. Over time, the particles are compressed and form what type of rock? A. Igneous B. Basinic C. Metamorphic D. Sedimentary
Answer: D. Sedimentary
Explanation:
Sedimentary rocks are formed overtime are different particles of sand, shells, pebbles and other fragments of materials form layers and harden into rock.
The particles are compressed and form sedimentary rocks in the ocean floor. Ocean floor is the bottom of the waterbody. Thus, the correct option is D.
What is Ocean Floor?The seabed or ocean floor is the bottom of the ocean. All the floors of the ocean are known as 'seabed'. The structure of the ocean floor of the global ocean is governed by the plate tectonics.
Most of the parts of the ocean are deep, whereas the ocean floor is known as the abyssal plain. The seabed also known as the seafloor, ocean floor, and ocean bottom is the bottom of the ocean.
The ocean floor can be divided into three distinct regions which are the continental margins, abyssal plains, and the mid-ocean ridges. The ocean floor has rocks which are called basalt. Here, the basalt particles are compressed which forms the sedimentary rocks. Sedimentary rocks are formed by accumulation of minerals.
Therefore, the correct option is D.

how your innate immunity protects you from the pathogens you encounter.
Answer:
General defenses are the first line of defense and are collectively called: the Innate Immune System. This system is called "innate" because it is genetically encoded, the traits that protect us from infections can efficiently be transmitted to our offspring.The innate immune system recognizes molecular structures that are produced by pathogenic microorganisms. Microbial substances that stimulate innate immunity are often shared by different classes of microbes and are called molecular patterns associated with pathogenic microorganisms
Explanation:
The first defenses that external agents face when trying to penetrate the body are totally nonspecific and are made up of the anatomical, physical, chemical or biological barriers characteristic of each location, while some, such as temperature, are systemic. Between all they make up innate immunity. The importance of these barriers is reflected in the ease with which infections are acquired when one of them fails. Innate cell recognition systems are based on surface or intracellular proteins of epithelial cells, neutrophils, macrophages, and dendritic cells and on soluble cytoplasmic receptors. All these receptors are generally called PRRs (Pattern Recognition Receptors) and bind to PAMPs (Pathogen-associated Molecular Patterns) molecules expressed only by the pathogen (bacterial lipopolysaccharides, carbohydrates and lipoproteins, peptidoglycans, RNA, DNA, etc.). Innate immunity constitutes a less evolved and specific defense than the adaptive one, since the same mechanism (cells, soluble factors, etc.) acts against different agents. Furthermore, repeated exposures to a foreign molecule or agent elicit a similar response and with the same intensity in all of them; that is, it lacks immune memory. The fact that it is a less evolved and specific response is compensated by its speed, since it occurs in hours, and because its intensity is not linked to a previous contact with the foreign agent. Furthermore, its action is essential for the subsequent development of the adaptive immune defense, to which the agent must be exposed once these barriers have been overcome.

Describe the environmental conditions that extremophiles are able to live in. Describe the environmental conditions that extremophiles are able to live in. Extremophiles were microbes that could only live in conditions that prevailed early in Earth's history when environments had high temperatures and pressure and lacked oxygen. Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions. Extremophiles can only survive in habitats where there are extreme changes in close proximity, such as hydrothermal vents at the bottom of the ocean, where water as hot as 300°C emerges and mixes with 4°C seawater. Extremophiles are able to tolerate extreme conditions found in space such as a near vacuum and temperatures in excess of 300°C or several hundred degrees below 0°C.
Answer:
Extremophiles includes those microbes that thrive in very high-salt, high-temperatures, low-temperature, high-pressure, low-pH, or high-pH harsh conditions.
Explanation:
Extremophilic organisms are life forms that can grow in extreme environmental conditions, such as the above mentioned. In general, extremophiles are prokaryotic organisms (i.e., archaea and bacteria), although there are some eukaryotic species that are considered extremophilic organisms. Extremophiles are classified into two main types: 1-microorganisms that live in extreme conditions and 2-microorganisms that have the ability to tolerate extreme environmental conditions. Extremophiles are extremely important both in basic and applied research. An example of this is the thermostable Taq DNA polymerase obtained from the bacterium Thermus aquaticus (an extremophile that lives in areas of high temperature and pressure), which is essential to carry out the Polymerase Chain Reaction (PCR).

why are summer days longer than winter days on earth ?
Answer:
3. The region of Earth => away from the sun.
Explanation:
In the summer months, the northern half of the Earth, where we live, tilts towards the Sun. The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. This means we get more sunlight, making the days longer.

how your innate immunity protects you from the pathogens you encounter.
Answer:
The innate immunity in living organisms protects them from the pathogens they encounter daily.
Explanation:
Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.
For example, Avian flu is a strain or variant of the Influenza virus which predominantly causes a disease in birds such as chickens. The virus responsible for the Avian flu can be passed from birds to humans; when anyone comes in contact with a bird that is carrying the virus i.e a sick bird with Avian flu.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
Also, immunization can be defined as the process of boosting an individual's immunity or immune system against antigens (immunogen) which cause diseases by the administration of vaccines.
Basically, immunization helps to improve the functions of the antibodies, B cells, T cells etc.
If a person becomes infected with a pathogen, such as a virus. The internal stimulus that mainly takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).
