It is called <span>hemoglobin</span>
Answer:
<h2>c. glucose</h2>
Explanation:
it is broken down to produce energy
The answer is;
- Biotic – planktons
- Abiotic - temperatures
A biotic factor that affects viral activity is planktons and bacteria in the sea. Viruses insect bacteria, planktons and use their machinery to replicate themselves. Viruses, therefore, lyse and kill many bacteria in the seas and make carbon available in the oceans- hence drive the carbon cycle.
Temperature is an abiotic factor in the sea that affects viral activity. Higher temperatures or too cold waters will reduce viral activity in the oceans and seas.
First statement. Let me know if you got it right.
Answer:
The fossils remains of arthropods, Echinoderms, Mollusk and other bilaterians appeared in Cambrian period and throughout the Paleozoic era.
Explanation:
Trilobites were marine group of arthropods that appeared in the Cambrian Period around 55.6 million years ago, eventually becoming extinct during the Permian Period. Most of the organisms were small, bottom-dwelling organisms that had fed on small organic matters in sediment on the sea bottom. The body is divided in three segments: head (cephalon), middle (thorax), and tail (pygidium). Many species had large, compound eyes. Fossils had define characters of having body divided in to head,thorax,and tail. Body had segmentation and citineious body layer.
