Answer:
B. natality + immigration = mortality + emigration
Explanation:
Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.
Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.
Some of the factors that influence migration selectivity are income level, age, education, gender etc.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Therefore, the equation which would create a stable population is given by the formula;
Natality + immigration = mortality + emigration.
Food webs normally start at the bottom and work their way up. Like the plants will be at the bottom, and then each level shows the animals getting bigger while losing energy. You continually lose energy as you work your way up an ecosystem, so normally there are only three or four levels. I hope this helps!
The analysis of total microbial genomes in an environment is called metagenomics and the total microbial genomes in an environment (or the total microbial community itself) is called a microbiome.
<h3><u>
Explanation:</u></h3>
The study that is associated with the genetic materials that are obtained directly form the sample in an environment refers to the term Meta genomics or ecogenomics or community genomics. It can be considered as the process through which the meta genome is produced.
The genetic material of the microbes such as fungi, bacteria, viruses and protozoa refers to microbiome. These microbes lives inside the body of humans. The weight may range upto 5 pounds for these microbiomes. Micorbiomes are the total number of micro genomes that are present in the environment.
Answer:
They have a camera-type eye which consists of an iris, a circular lens, vitreous cavity (eye gel), pigment cells, and photoreceptor cells that translate light from the light-sensitive retina into nerve signals which travel along the optic nerve to the brain.
