Answer:
1) 60x; 2) 150x
Explanation:
Total magnification = Power of the Ocular X Power of the objective
Power of Ocular = 15x
Power of Objective = 4x ; 10x
1)Total magnification = 15 X 4 = 60x
2)Total magnification = 15 X 10 = 150x
Answer:
Exoskeletons provide less mechanical leverage.
Explanation:
There are two types of skeleton in living beings: the endoskeleton (which vertebrates possess, is lined with epithelial tissue and has bones and cartilage) and the exoskeleton, a skeletal structure that is located outside the body of the living being. , is an external skeleton. They are common in invertebrate animals, which have no internal bone structure.
The exoskeleton is a tough but flexible outer layer, not formed by bones, unlike the vertebrate endoskeleton. Its function is mechanical, chemical and biological protection, avoid excessive water loss, muscle support and serves as a connecting point for legs, wings and other appendages. However, this type of skeleton provides less mechanical leverage.
On the other hand, the endoskeleton is the name given to the internal skeleton, which is inside the body. This body structure is mainly seen in vertebrate animals and has the function of supporting and moving the body, as well as protecting some internal organs. Unlike exoskeleton, the endoskeleton provides more mechanical leverage.
Answer:
(c) their inclusiveness.
Explanation:
The taxonomic classification has eight levels, they go from the more inclusive to the more exclusive.
The eight categories are: <u>Domain</u> which is the most inclusive level, that is to say, that the largest number of individuals are included in this level. There are three domains according to the cells types, and where they live. They are the Eukarya, Bacteria and Archaea. Domains are divided into <u>kingdoms</u>, they are the Plantae, protista, Eubacteria, Archaebacteria, Animalia and Fungi. After kingdoms the <u>Phylum</u> category comes, following Phylum is <u>Class</u>, various classes that are related will form a Phylum. The next category is <u>Order</u>, order is divided into <u>Family,</u> families are broken into <u>Genus</u>, where species are closely related between each other and finally the last category is <u>Especies identifier,</u> in this group there are unique characteristics that will identify a specie. With this classification we can see that we go from global groups to more specifics ones as the classification avances.
