Answer:
Arthropods invaded land about 100 million years before vertebrates. This fact most clearly implies that a. arthropods have had more time to co-evolve with land plants than have vertebrates
Explanation:
Arthropods are invertebrates animals. Its evolutionary ancestry dates back to the Cambrian period and they have had more time to co-evolve with land plants than have vertebrates. The vertebrates share a common ancestor. Scientists believe that the last common ancestor of all arthropods is a modular organism with each module covered by its own sclerite.
Answer:
The cell cycle is controlled by many cell cycle control factors, namely cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). Cyclins and Cdks, which are positive regulators of the cell cycle, activate cell cycle factors that are essential for the start of the next cell cycle phase.
Explanation:
Listen to pronunciation. (sel-SY-kul REH-gyoo-LAY-shun) Any process that controls the series of events by which a cell goes through the cell cycle. During the cell cycle, a cell makes a copy of its DNA and other contents, and divides in two.
The four inferences were love, hate, war and the liberties of death.
Is it due to attachement of bronken part of one chromosome to another. I hope this helps.
The bones in a bird are hollow, reducing its weight for flight, this is an example of ADAPTATION. The adaptive responses emerge as a consequence of different environmental pressures.
<h3>Adapatation and environment</h3>
Adaptation is an evolutionary process by which organisms adjust to the environment in which they live.
For example, the bones in a bird are hollow because this adaptive feature enables them to fly.
Adaptations are a consequence of the process of natural selection, i.e., the differential survival and reproduction of the fittest organisms.
