Answer: <u>Fungi
</u>
Explanation:
Organisms with the capacity to breathe anaerobically and aerobically are typically called obligate anaerobes. Obligate anaerobes are usually microorganisms- microscopic organisms.
Since the organism described is land-dwelling, chitinous and eukaryotic (containing a plasma membrane enveloped nucleus), they are most likely fungi. Chitin is a rigid, non-soluble carbohydrate utilized for structural purposes. Typically these organisms have strong, insoluble cell walls, are multi-cellular and can form filamentous networks of hyphae.
They create a tangled network of mycelia and may be:
- Septate, with walls between every cell or
- Aseptate without walls
The daughter cells come together to make another identical parent cell.
Answer:
Human impact
Explanation:
It is normal to the species to disappear, but it is not normal to do so as fast as they do this times.
The human, and its consumerism that exerts, are the causes of the force extintion of the species. Consumerism is the cause of greater amount of greenhouse gases, erosion due the exesive felling of trees, and for that, lower water retention, and so the water cycle changes. If the hand of the human changes something of the natural cycle, changes everything
Answer:
Secondary consumers.
Explanation:
In a trophic pyramid, there are conventionally four levels. From the bottom they are: Producers, Primary Consumers: Secondary Consumers, and at the top we have tertiary consumers. Each level generally consumes animals in the level below it. Producers consist of plants.

c, d, a, b, f, g, e
The impulse starts at the SA node that has its own contraction rhythm (but can be faster or slower depending on other impulses or hormones). That impulse travels then through the atria and is slowed down by the atrioventricular septum except for a region in the right atrium called AV node where the impulse has continuity. The impulse travels then to the ventricles through the AV bundle. The impulse continues through bundle branches to other fibers: Purkinje fibers. These Purkinje fibers cause then a contraction that goes from the apex of the heart and rapidly through the ventricles.</span>
