Answer:
Biodiversity loss
Urban development is the major cause of biodiversity loss because of constructions of building, roads, dams etc. in course of a developing urban area requires the removal of forests, natural aquatic and terrestrial ecosystems which are rich sources of biodiversity. As, forest or natural habitat are removed floral species get wiped out and faunal species move to other location, therefore, biodiversity of a region get lost.
Answer:
<em>The correct option is C) chlorine</em>
Explanation:
Sea water contains salts in abundance. It can be described as the water which makes up the oceans and the seas. It is known to contain approximately 96.5% water and 2,5 percent of salts. Sodium and chloride ions are the most abundant salt ions to be found in the sea. The concentration of chloride ions is 0.546 mol/kg and the concentration of sodium ions is 0.469 mol/kg. Hence, chloride ions are slightly abundant than sodium ions.
Answer:
a) The genotype of her father = "aa".
The genotype of her mother = "Aa".
The genotype of Sally is "Aa".
b) 1/2
c) 1/2
Explanation:
a) Sally's father has alkaptonuria. So, the genotype of her father is "aa". Her mother is normal. Since her brother is affected by the disease, he should be homozygous recessive (aa). This means that the mother also has one copy of "a" allele and is heterozygous dominant (Aa). A cross between Aa (mother) and aa (father) would give 50% affected progeny with "Aa" genotype. So, the genotype of Sally is "Aa".
b) The genotype of her mother= Aa
The genotype of her father = aa
Aa x aa = 1/2 Aa (affected): 1/2 aa (normal)
So, if Sally's parents have another child, there is a 1/2 probability that this child will have alkaptonuria.
c) The genotype of Sally = Aa
Genotype of the man Sally marries= aa (since he is affected with alkaptonuria)
Aa x aa= 1/2 Aa (affected): 1/2 aa (normal)
There is a 1/2 probability that their child will have alkaptonuria.
Answer: Environmental responsibility. ... Respect the environment, making rational use of natural resources and taking steps to prevent pollution from the different processes involved in our industrial operations. Promote the sustainable use of raw materials and natural resources. In fact, our cognitive ability and understanding of nature obliges us to maintain the integrity of the environment. So we must change how we influence the land. We must respect the natural order of things and find a way to live accordingly.
