Taxonomic groups are used for biological classification. There are eight main taxonomic groups: domain, kingdom, phylum, class, order, family, genus and species, with the domain as the most inclusive and species as the least inclusive. If we take a look on Mammalia and Hominidae classification, we can assume that Mammalia represents class, and Hominidae represents family:
1. Domain: Eukarya
2. Kingdom: Animalia
3. Phylum: Chordata
4. Class: Mammalia
5. Order: Primates
6. Family: Hominidae
7. Genus: Homo
8. Species: Homo sapiens
Answer:
Class and Family
Explanation:
Aristotle's divided living beings into plants and animals and Linnaeus created a method of classification.
Aristotle's divided them into two groups:
which would have subgroups organized according to the environment in which they lived, being characterized as
The Swedish naturalist Carl von Linnée (1707-1778), better known as Linnaeus, defined structural and anatomical characteristics as a classification criterion.
With this information, we can conclude that Aristotle's divided living beings into plants and animals and Linnaeus created a method of classification.

B. motor neuron -> interneuron -> sensory neuron
C. interneuron -> sensory neuron -> motor neuron
D. None of these
Answer:sensory nuerone to internuerone to motor neurones
Explanation:
The sensory nuerone usually receive inputs from the receptors cells in the skin,organs,and other parts of the body.
These receptors send signals as action potential to the spinal cord to the brain.(CNS).
Synapse take place at the synaptic junctions, in the spinal cord with the internuerone.
The latter transmit the action potential to the motor neuron which synapse with the internuerone and transmita signal to the neuromuscular junction where it synapse with the muscels at the toe.
The action potentials causes influx of calcium ions and the relase of acetylcholine neurotransmitters for action potential to reach the toe muscles (effector)for contraction
The correct options for the question are as follows:
weaken viral respiration.
destroy viral mitochondria.
reduce the ability of the virus to absorb cells.
prevent the virus from entering cells.
Answer:
The correct answer is - prevent viruses from entering the cell.
Explanation:
False.
Villi actually increase the surface area for absorption in the small intestine.
The statement 'The villi decrease the surface area of absorption' is False.
In fact, the villi in the small intestine increase the surface area available for absorption. Villi are small finger-like projections that line the inner surface of the small intestine. They are covered with tiny microvilli, which further increase the surface area. This increased surface area allows for more efficient absorption of nutrients from digested food in the small intestine.
Without the villi, the surface area for absorption would be significantly reduced, making the digestion process less efficient.

Answer:
true
Explanation:
b. Coral reefs provide aquatic organisms with resources but derive no benefits in return.
c. Coral reefs provide resources for aquatic organisms and derive resources from other organisms as well.
d. Aquatic organisms live independently of coral reefs.
The correct answer is - c. Coral reefs provide resources for aquatic organisms and derive resources from other organisms as well.
The corals are essential part of the marine ecosystems. They are feeding upon zooplankton, but also their polyps get sugar that is produced by the algae living on them. Also, the corals provide much needed shelter for lots of marine animals, but also are on the menu of some, like the starfish for example.
