Answer:

Paleontologists thinks that the younger fossils are a species that underwent an-agenesis, gradually evolving a new morphology or/and the younger fossils are a new species that branched off the older one, rapidly evolving a new morphology.

Explanation:

Fossils are the safeguarded remains or hints of creatures, plants, and different life forms from an earlier time. Fossils range in age from 10,000 to 3.48 billion years of age. The perception that specific fossils were related with certain stone layers drove nineteenth century geologists to perceive a land timescale. Like surviving life forms, fossils differ in size from minuscule, similar to single-celled microscopic organisms, to monstrous, similar to dinosaurs and trees.

Fossils give strong proof that living beings from the past are not equivalent to those discovered today; fossils show a movement of advancement. Fossils, alongside the similar life systems of present-day life forms, comprise the morphological, or anatomical, record.

By contrasting the life structures of both present day and terminated species, paleontologists can deduce the ancestries of those species. This methodology is best for life forms that had hard body parts, for example, shells, bones or teeth. The subsequent fossil record recounts the account of the past and shows the development of structure more than a great many years.

complex chemical processes such as photosynthesis occur in a controlled series of steps with the help of ?
Iteru [2.4K]

Answer:

Chlorophyll and sun light.

Explanation:

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Carbon dioxide + water + energy →   glucose + oxygen

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

The glucose is converted into pyruvate and produces ATP through cellular respiration and produces oxygen.

What do you call the end of a straw wrapper that a waiter leaves on your straw when serving your drink?
daser333 [38]

The waiter tears the raised part of the straw wrapper a few inches from either end and he pulls until a piece of the wrapper is entirely removed. The exposed part of the straw is what is then placed in the drink, leaving the remaining wrapper for the customer to remove himself. This will assure the customer that the waiter has not touched the straw with bare hands. The part of the straw that has remained is called a straw lace, or a drinking straw sleeve or a strawphylactic.
