The ability to flyThe quinine exoskeleton

Explanation:

The reason why insects are so successful in diversifying and adapting to different environments is closely related to their morphological and physiological adaptations.

In general, and compared with other groups, insects are small-sized. This characteristic also turns to be important and advantageous. Being small helps them find refuge in any place, escaping from predators, and as they are small they do not need too much food to survive.

Insects have a light and resistant exoskeleton made of chitin, a nitrogenated polysaccharide. This structure turns to be very important because it is impermeable to water, which helps the insect to avoid dehydration, helping the invertebrate to inhabit many different kinds of habitats. Also, the exoskeleton protects the arthropod from toxic substances and their natural enemies attacks, such as predators and pathogens

Insects are the only invertebrate with wings. Flying capacity is probably the most important adaptation that helped insects in their dispersion process to new areas. Being able to fly allows them to move huge distances looking for food, refuge, or mate. However, during evolution, some groups have lost the wings or have reduced their flying capacity.

The short life cycles, and their numerous litters, also helped them in their diversifying process.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust. the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles. three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

Answer from: Quest

The main role of dna in the cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where proteins are assembled on ribosomes in the cytoplasm. mark brainliest, my work is good.

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).

When does a spring tide occur? question 9 options: they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur twice a year in the spring and fall. they occur on the date of the vernal equinox each year, no matter what stage the moon is in. this is why they are called spring tides. they occur when the sun, moon, and earth are at 45-degree angles from each other. this happens once every spring. they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur all year long.
