Answer:
It is made of matter and contains twenty-four molecules.
I believe it's "pollen".
When the pollen grains are washed down into lakes/rivers, scientists can take a sample of the sediment layers and see what plants were growing at that time. They can then make inferences about the climate and how that affected the plants growing there.
Hope this helps!
Flower hat jellyfish, a native of the Southern Japan is the animals which look like a flower, due to the presence of pinstriped bell on it. It also has tentacles, to sting, catch and eat small fishes. It causes rashes on the humans if it stings them.
Answer:
b. Mitochondrial respiration
Explanation:
Mitochondrial respiration of plants involves the participation of two major electron transport routes:
1. Cytochrome c oxidase route: cyanide sensitive and coupled to three energy conservation sites.
2. Cyanide-insensitive alternative route: involves alternative oxidase (AOX), branches off the cytochrome oxidase route into the ubiquinone pool, with no energy conservation thereafter as AOX is able to directly oxidize ubiquinol and reduce oxygen to water.
Regardless of the route followed, mitochondrial breathing is a long and complex process. However, it is through this breath that at a given moment electrons are passed to oxygen through a carrier channel in the inner mitochondrial membrane. This happens when cytochromes to and some molecules that have a heme group (with an iron atom) and are linked to a transmembrane protein that connects the matrix to the mitochondrial intermembrane space and have two copper atoms that allow the transport of electrons to the final acceptor, oxygen (O2).
The definition 'All the organisms and their physical and chemical environment within a specific area' best describes the ecosystems.
<h3>What are ecosystems?</h3>
Ecosystems can be defined as particular geographic areas that exhibit certain abiotic factors which interact with a community (i.e., a group of populations) to shape the environment.
In conclusion, the definition 'All the organisms and their physical and chemical environment within a specific area' best describes the ecosystems.
