Organisms whose cells do not contain a well-defined nucleus are placed in the kingdom Fungi is false.
False.
<u>Explanation:</u>
Fungi are eukaryotes that contain many membrane-bound organelles and a nucleus. The Fungi kingdom consists of many living organisms though fungi are more plant-like organisms but are closely related to animals.
Fungi are generally heterotrophic because they use the organic compound for a source of energy.
Many fungi produce haploid cells that undergo mitosis to become multicellular. They play an important role in the ecosystem because they break down organic plus inorganic materials into molecules.
Answer:
Date and latitude interact to determine photoperiod, the daily period of daylight. This interaction has important implications for latitudinal migrants for whom daylight may be a resource or for whom photoperiod regulates annual transitions in life‐history stages (i.e. birds).
Using an established formula, we developed user‐interactive, animated models that enable the visualization of how latitude and date determine photoperiod for latitudinal migrants. We also calculated the photoperiodic schedules for a broad range of hypothetical migratory programmes and real migratory programmes newly available through the proliferation of citizen‐science data. This enabled us to infer the limitations some migratory programmes place on mechanisms for photoperiodic regulation of annual breeding.
In the vast majority of cases, the act of migrating elevates annual daylight exposure. This raises the hypothesis that daylight availability selects for latitudinal migration, potentially contributing to its evolution in animals such as diurnal birds with limited time during the spring and summer to feed young. However, photoperiodic mechanisms regulating annual cycles could constrain the evolution of such migrations, depending on how they affect photoperiodic schedules. Most migratory programmes are consistent with known mechanisms of avian photoperiodism, but the range of feasible mechanisms declines for transequatorial migrants, which experience semi‐annual, 180°‐phase‐shifts in their photoperiodic cycles.
Understanding photoperiodic constraints on migration are particularly important in this age of changing latitudinal distributions and phenologies driven by climate change.
Hope this helps and have a great day!!! :D
Answer:
Indpendant veriable cigarette smoking on lung cancer.
Dependant veriable:The number increase
Explanation:
It is A. Those are all decomposers, the other answers like C are all animals. Decomposers are are biotic organisms that break down basically dead plants or animals.
Translation occurs in the nucleus to produce a pre-mRNA molecule. The pre-mRNA is the processed into the mature mRNA which exists the nucleus and is translated into the cytoplasm.
So, the answer is B) NUCLEUS
