Answer:
Some factors that may cause a decrease in population size:
- a high mortality rate due to an infectious disease
- a low birth rate
- a high mortality rate due to interspecific competence
- a high emigration rate
Explanation:
In biology, population size (N) refers to the total number of individuals in a given population. The four main factors that affect population size are birthrate (natality), death rate, immigration rate (i.e., the number of individuals of a given species that move into a population), and emigration rate (i.e., the number of individuals of a given species that move out of a population). Both birthrate and immigration are known to increase N, while death rate and emigration are rates known to decrease this value.
This question is incomplete as no options are given. However, urbanisation typically leads to a greater percentage of impermeable surfaces, such as roads, parking lots etc. Water is then unable to filter into the soil and groundwater as much as it would on natural land. What then occurs is much more runoff in urban areas during rainfall. This has been problematic in major cities in the developing world, where storm water drains are not maintained. Rainfall can easily result in flooding, and floods can be much worse in urbanised environments. We must also consider that there will be reduced groundwater recharge in urban areas from rainfall, as less water infiltrates the soil. Interestingly, in urban areas, it is generally accepted that up to 60% of tap water is lost through leaks, many underground, so groundwater may be recharged through lost tap water.
Nucleic acids have the most control of traits and inheritance.
Answer:
<h2>Dense connective tissue.</h2>
Explanation:
This is a type of connective tissue that has fibers, which are composed of collagen. You can refer to the image attached to see the parallel bundles of these collagenic fibers.
So, basically this formations help to forms strong tissue like tendons or ligaments.
The Golgi apparatus deals with packing of the cell!
