The correct answer is - chromosomes align at the spindle equator.
Explanation:
Chromosomes move and align at the spindle equator during the metaphase stage of mitosis and other given events take place during the anaphase stage of the mitosis cell division. Metaphase is the second phase of the M-phase of mitosis division whereas anaphase is the third phase.
The metaphase is characterized by the alignment of the chromosomes at the equator whereas the anaphase is separating the chromosomes pulled towards the poles and division of centromeres.

Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Energy pyramids, however, are always upright. Why?
Answers
Answer:
The correct answer is - as energy lost at every trophic level.
Explanation:
In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.
The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.
As the energy is lost at every trophic level, the energy pyramids are always upright. A further explanation is below.
In whatsoever biological environment, the energy pyramid always seems to be straight, unlike some of the other pyramidal, including such biomass, which might be diamond-shaped, overturned, as well as upstanding.Essentially the food chain is simply a pyramid, and there is always some power loss as that of the primary consumers throughout the chain increases.
Thus the response above is right.

You are concerned with surveying the protozoa in the arboretum soil. While most commonly thought to live exclusively in aquatic environments, protozoa can play an important role in the nutrient cycling that takes place in soil. In addition, protozoa can help maintain the proper balance of bacterial populations within soil, as bacteria are a primary source of food for protozoa. Protozoa are extremely diverse. However, there are three characteristics common to all organisms called protozoa. What are these three characteristics
Answers
Answer:
eukaryotic, unicellular, without a cell wall
Explanation:
Protozoans are single-celled eukaryotes that generally move through cilia, flagella, or amoeboid motion. After their discovery, protozoans were considered as single-cell animals due to their animal behavior (including predation and motility), and because they don't have a cell wall, as observed in algae and plants. Some examples of protozoans include Paramecium, Amoeba, and Trypanosoma. Nowadays, the term 'protozoans' is still used to describe unicellular eukaryotic organisms from the Protista kingdom that are heterotrophs, i.e., unicellular microorganisms that acquire energy and nutrients from other organic sources, especially plant and animal matter.
