Density, dispersion, growth
Explanation
Population refers to the total number of all members of a species occupying a particular area or habitat at a given time. Populations are not static but change in size, structure and organization. Some of the characteristics of population are:
- Density which refers to the number of members of a species per unit area or volume.
- Dispersion refers to the spread and distribution of individuals of a species within a habitat.
- Growth is the rate of increase or decrease in the number of individuals in a population which is balanced by birth rate and death rate.
The issues that affect population include competition, predation, emigration, diseases and parasites.
Answer:
The first one is the second one, and the second one is the third one.
Explanation:
The answer is <span>A) All future somatic cells of the organism will contain the (2n + 1) number of chromosomes.
An egg cell and a sperm cell fuse to develop a new organism in a process called a fertilization. As a result, a zygote is formed. When the </span>egg cell containing the (n+1) number of chromosomes combines with a sperm cell containing the (n) number of chromosomes, the zygote will have (n + n + 1), which is (2n + 1) number of chromosomes. The zygote is the first cell of the new organism. It undergoes mitosis resulting in somatic cells where all of them will contain the same <span>number of chromosomes as the zygote, which is (2n + 1)</span>
Answer:
C) a mature river
Explanation:
The channel on the image shows a meandering river. This basically means that the river managed to erode the banks and it has taken a snake-like shape, better known as meander. A river that exhibits such a thing is a mature river. This can be supported by the fact that the river needs long time to be able to erode the surrounding area, especially when it comes to flatter land. A young river will be mostly straight and will have its flow determined by the landscape around it, but a mature river has had the time to make its own path, to erode parts o the landscape, and take a certain shape, in this case a meander.
