Answer:
about the Trilobites is =Trilobites ( /ˈtraɪləˌbaɪt, ˈtrɪ-, -loʊ-/;[4][5] meaning "three lobes") are a group of extinct marine artiopodan arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years.[6] . and about the algae is =Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.
Explanation:
<h2>Some bacteria are facultative anaerobes, which usually produce ATP by aerobic respiration but are also capable of switching to fermentation when there is a lack of _____OXYGEN____ in their environment. </h2>
Answer: Anterograde direction.
Explanation:
Choline acetyltransferase is an enzyme made in the body of a neuron and that needs to be transferred to the axon terminal to perform its function. Its function is to bind acetyl-CoA to choline to form the neurotransmitter acetylcholine.
The movement toward the cell body is called retrograde transport and the movement toward the synapse is called anterograde transport. So, since it is produced in the body of the cell and it has to go to the axon terminals, the choline acetyltransferase is transported in the anterograde direction.
This type of transport is responsible for the movement of organelles such as mitochondria, lipids, synaptic vesicles, proteins from a neuron cell body through the cytoplasm of its axon called the axoplasm. <u>Because axons can sometimes be meters long, neurons cannot rely on diffusion to carry products to the end of their axons</u>. Dynein is a motor protein involved in this retrograde axonal transport. Its light chains bind cargo, and its globular head regions bind the microtubule, "moving forward" along it.
It’s carbon dioxide + water > glucose + oxygen + water and energy produced in the form of ATP
