Answer:
centrosomes and lysosomes
Explanation:
lysosomes are used in digestion i believe
hope this is correct and helps :)
Sound waves enter the external ear and are funneled toward the tympanic membrane by the shape of the outer ear.Variation in air pressure due to sound waves causes the tympanic membrane to vibrate. The wave frequency will determine the vibration rate.Tympanic vibrations cause the malleus to move. Because the three ossicles are connected, this vibration is transduced to the stapes via the incus.Movement of the stapes vibrates the oval window. Significant amplification of sound waves occurs due to the small size of the window.Pressure changes transduced through the oval window vibrate the perilymph in the scala vestibuli which are transmitted across the vestibular membrane to the endolymph of the cochlear duct, and also up the scala vestibuli and down the scala tympani much the way <span>waves move through the ocean.</span>
Answer:
The correct answer is D.
Explanation:
The plants are grouped formally into 12 phyla (phylum plural) and are collected in four groupings. These four groupings are based on the history of the evolution of important plant characteristics:
- Nonvascular plants evolved earliest. They are distinct from the algae because they preserve the embryo inside of the reproductive structure after fertilization. There is no vascular tissue, xylem, and phloem for these plants to convey nutrients, water, and food. For example, moose, liverwort, and hornworts. These plants do not grow very high without vascular tissue.
- Vascular seedless plants have evolved into non-vascular tissue but no seeds. The fern, fern, club moss, and horsetails are examples. These plants could grow larger with vascular tissue.
- Gymnosperms have evolved into seeds but have no blooms. For example, redwood, fir, and cypress trees. Gymnosperms. Gymnos in Greek means "naked"; the gymnosperm seeds are bare, not floral.
- Flowers or angiosperms have developed into vascular tissue, seeds, and flowers. Angiosperm for example includes magnolia, roses, tulips, and tomatoes.
The answer is : A ) <span> prokaryotes do not have organelles with membranes.

<span>Cardiac cells unlike all the other cells in the body have a branching morphology another unique feature are the intercalated disks between the muscle fibers which skeletal muscle cells do not have they do both have myofibrils though.</span>
