When a population exhibits adaptation, it indicates that the population has responded to a pressure from the environment in a way that causes the prevalence of beneficial features to rise over time.
Natural selection only affects heritable traits in populations, favoring advantageous alleles and reducing the frequency of harmful alleles, a process known as adaptive evolution. Natural selection only affects heritable traits in populations. However, natural selection affects whole organisms rather than specific alleles. A person may have a genotype that is extremely advantageous and a phenotype that, for example, boosts fecundity, but if that person also contains an allele that causes a fatal childhood ailment, the fecundity phenotype won't be passed on to the next generation.

Answer:
C. It is larger in urban areas
Explanation:
- Carrying capacity is the number or the amount of pressure of species on the earth's ecological system can bear or can carryforwards and can be sustained by giving food, water, and necessity available to the environment.
- The ecological footprint is a measure or a way to estimate the pressure on the natural resources by these species by taking in the future possibilities and limitations. Estimated in terms of the demands and the biocapacity of the ecosystem.
- <u>The urban area carrying capacity is a result of interaction of the multiple subsystems and due to the large human activities the urban areas have low levels of the carrying capacity as they are not natural settings and put pressure and huge load over resources.</u>
An estuary is where salt water and fresh water meet. Estuaries are usually found at the edge of the coast, where the ocean water, or salty water, meets river, lake, any fresh water source, water.
A tributary is something completely different. It is a, usually smaller than the main river or lake, river/stream stemming off a bigger river or lake, or flowing into that river or lake.
Basically add up all the sides... And that's the perimeter don't forget to add your units
