Increase in urbanization will lead to increase in the number of people who are living in an urban area and it will also lead to increase in development in that area. The increase in development can come in form of construction of industries, which release large amount of waste products that pollute the air. This will lead to air pollution and reduce air quality. Development can also be in form of availability of electricity, that makes it possible for people to operate different electrical gadgets such as radio and television, which can result in noise pollution. Increase in the number of people who operate motor vehicles will also lead to increase in air pollution, which is caused by fossils fuel.
There are two types of plant tissues: meristematic tissue found in plant regions of continuous cell division and growth, and permanent (or non-meristematic) tissue consisting of cells that are no longer actively dividing.Meristems produce cells that differentiate into three secondary tissue types: dermal tissue which covers and protects the plant, vascular tissue which transports water, minerals, and sugars and ground tissue which serves as a site for photosynthesis, supports vascular tissue, and stores nutrients.Vascular tissue is made of xylem tissue which transports water and nutrients from the roots to different parts of the plant and phloem tissue which transports organic compounds from the site of photosynthesis to other parts of the plant.The xylem and phloem always lie next to each other forming a structure called a vascular bundle in stems and a vascular stele or vascular cylinder in roots.Parts of the shoot system include the vegetative parts, such as the leaves and the stems, and the reproductive parts, such as the flowers and fruits.
Answer:
The prokaryote divides by asexual mode of reproduction.
Explanation:
The concept of species which defines a species as a group of individuals of a population which can interbred and produce a fertile progeny is applicable to the organism which can reproduce sexually.
Since the bacteria divide through asexual means and not through sexual ways therefore the concept of defining a species becomes complicated and does not apply.However the concept of species in prokaryotes is still a topic of research.
Thus, the biological concept of species is not applicable to prokaryotes.
Answer:
In the traditional phylogeny platyhelminthes is depicted as a lophotrochozoan phylum. What probably led to this change?
The removal of the acoel flatworms (Acoela) from the Platyhelminthes allowed the remaining flatworms to be clearly tied to the Lophotrochozoa.
