The major promise of biometrics is to replace reusable passwords - True
Biometric authentication is seen as a secure alternative to the traditional knowledge-based methods such as usernames and passwords. Biometrics relies on unique physiological traits like fingerprints, face recognition, voice recognition, and eye scans for verifying identity. Such traits are believed to be less susceptible to theft and duplication than passwords. In practical scenarios, devices like smartphones and laptops are already adopting biometrics in addition to or in place of passwords.
Biometrics offer a higher convenience, and for some users, an increased sense of security. However, it is important to note that if the biometric data is transmitted over a network, it could be just as vulnerable as passwords to certain types of attacks, and biometrics are not necessarily perfect and can sometimes be misled or have their data compromised.

Compounds that contain a fused ring system are called
Polycyclic aromatic hydrocarbons (PAHs) are compounds with fused ring systems, while heterocyclic compounds have rings with non-carbon atoms like nitrogen.
Explanation:Compounds that contain a fused ring system are known as polycyclic aromatic hydrocarbons (PAHs). These structures consist of multiple aromatic rings, such as benzene rings, that are joined together and share one or more sides or edges. For instance, the basic structure of steroid hormones includes a system of three six-membered rings and one five-membered ring that are connected in this way. These rings have bridgehead carbons that link them together. Furthermore, some cyclic compounds contain atoms other than carbon, called heterocyclic compounds. Notable examples are purine and pyrimidine, which are key components in nucleic acids and contain nitrogen atoms within their fused ring structures.
what type of consumer is a flagfish?
Answer:
algae
Explanation:
Flagfish, or dinoflagellates, are generally considered to be primary producers due to their ability to photosynthesize. However, some also consume other organisms, which could classify dinoflagellates as primary or secondary consumers. Some dinoflagellates are filter feeders, a type of consumer that strains food particles from the water.
Explanation:A flagfish, also known as dinoflagellates, fall within the group of organisms called the Chromalveolata. The dinoflagellates are mostly marine organisms and are an important component of plankton. They possess various nutritional types which include being phototrophic, heterotrophic, or mixotrophic. Dinoflagellates use chlorophyll a, chlorophyll c₂, and other photosynthetic pigments which helps them to photosynthesize. Additionally, these organisms have two flagella, that help them move.
In the context of the food chain, dinoflagellates are primary producers. However, some can also consume other organisms, acting as primary or secondary consumers depending on their diet. Certain dinoflagellates are known to produce neurotoxins that can cause paralysis in other organisms, posing a threat when ingested.
An interesting example from the Opisthokonts, are the choanoflagellates. The single, apical flagellum in these protists is surrounded by a contractile collar composed of microvilli, which is used to filter and collect bacteria for ingestion by the protist. This classifies them as filter feeders, a type of consumer that strains food particles from the water.

Why are lichens a good pioneer species after a volcanic eruption?
Answer:
The pioneer species are defined as those species that are very strong and hardy and also they have the capability of enriching the soil particles that favor their growth and development.
The lichens are considered to be a good pioneer species because they have the ability to settle on the surface of the bare rocks, where they can produce acid that allows the rock to disintegrate and results in the generation of soil particles.
Thus, the lichens are a pioneer species that can evolve rapidly after an eruption of a volcano.
The presence of vesicles in an igneous rock is evidence that the source melt ________.
The presence of vesicles in an igneous rock is evidence that the source melt contained dissolved volatile. The correct option is D.
What are igneous rocks?Igneous rocks are those rocks that are formed by the cooling down of molten magma and rocks from volcanoes on the surface of the earth or the molten magma present inside the earth's crust. Some common igneous rocks are andesite, basalt, rhyolite, etc.
There are four types of igneous rocks. The y are felsic, intermediate, mafic, and ultramafic. The igneous rocks are crystalline solids. Spaces are present in between these rocks. These are called small vesicles. These vesicles are formed due to the accumulation of air in between the rocks.
Thus, the correct option is D. Contained dissolved volatile.
