The answer is 4 . The population will begin to decrease to depletion of resources and increased competition. This will cause an increase in death rate of the paramecium population as compared to birth rate. This phase follows the latent phase where the population remains the same over time as the population reaches carrying capacity and the birth rate equals death rate

1. The plant life that is characteristic of a biome depends upon:

eimsori [14]

Answer:

D. all of the above

Explanation:

Biome refers to a large and relatively distinct terrestrial region having similar climatic conditions regardless of where it occurs on Earth. The characteristic climatic conditions (temperature and precipitation being the most important ones) and soil type of each biome type determine the type of plant species found there. Therefore, each biome is characterized by specific flora.

For example, a desert biome is a temperate or tropical biome characterized by a lack of precipitation, seasonal variations in temperature and poor soil type with low organic matter that limits plant growth. Desert biomes have only the plant species that can survive these harsh conditions.

Is infant circumcision ethically necessary?

Nostrana [21]

The answer is that infant circumcision is not ethically necessary. The reason to this is that there are no proof of evidence as to why it is ethically necessary for it to be done to an infant. It is also because other medical professionals thinks that doing circumcision in an infant will create issues in terms of their health, producing complications. That is why it is not ethically necessary for it to be done on an infant.
