This phase in the life cycle of a plant is the asexual, spore-bearing generation of the plant, featuring diploid cells. This means the cells of the plant in this generation or phase have two sets of chromosomes in their cells. The zygote or fertilized cell is what conduces to form the sporophyte.

Answer:
Cobalt Co
Explanation:
Co and Zn can fully replace each other, except perhaps for small individual requirements that are met by minute metal concentrations supplied as contaminants.
Answer:
True.
Explanation:
There are four phases which occur during karyokinesis, these are -
- Prophase
- Metaphase
- Anaphase
- Telophase
Telophase is the last phase of karyokinesis. The main events that occur during telophase are-
- Uncoiling of chromosome occurs
- Chromatin is formed
- Spindle breaks down
- Nuclear membrane or nuclear envelope if reformed
Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.
That would be a hypothesis
Hope this helps you :)))
Answer:
a) Humans depend upon other organisms for food and oxygen
Explanation:
Biodiversity refers to the richness in the species of organisms on Earth i.e the variety of biological organisms on the Earth. The importance of biodiversity cannot be overemphasized because of our dependence on the sustainability of biodiversity in our ecosystems.
The loss of biodiversity, which is becoming rampant by the day, is a major concern to us because we humans depend upon other organisms for food and oxygen. Humans are strictly heterotrophic and hence are reliant on variety of organisms for food. Plants also release oxygen gas via their photosynthetic process, which is key to our survival as a population.
