Answer:

Red blood cells are considered cells, but they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria. Red blood cells cannot divide or replicate like other bodily cells. They cannot independently synthesize proteins,The nucleus is the cell's brain which controls much of its functions. An animal cell or eukaryotic cell will therefore die without a nucleus. The cell would not know what to do without a nucleus and there would be no cell division. The synthesis of proteins will either stop or shape wrong proteins.When red cells die, hemoglobin is broken up: iron is salvaged, transported to the bone marrow by proteins called transferrins, and used again in the production of new red blood cells

What reasons besides being necessary for the methane cycle, can you think of that might
Stella [2.4K]

Titan's rivers, lakes, and seas of liquid methane and ethane could provide a habitable environment on the moon's surface, though any life there would most likely be very different from life on Earth.

Methane gas is effective at trapping heat and burns quickly. As a result, methane is one of the most important human fuels. Furthermore, methane in the atmosphere helps to regulate the Earth's climate.

Over the first 20 years after it enters the atmosphere, methane has more than 80 times the warming power of carbon dioxide. Even though CO2 has a longer lasting effect, methane drives warming in the short term. Methane from human activity is responsible for at least 25% of today's global warming.

As a result, methane not only contributes to global warming directly, but also indirectly through the release of carbon dioxide.

During the Devonian period of Gondwanaland what were the two organisms that thrived?
gulaghasi [49]

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.
