B. Organize Seminars
C. Create a Tax collection program
2.
A. Recycling and waste disposal
B. Poaching
C. Deforestation
<u>Correct Option:</u>
<u>Organize seminars</u> to educate other students about the deteriorating environmental conditions and the steps needed to improve the area. Also, encourage other students to volunteer for workshops about <u>deforestation</u>.
<u>Option:</u> B and C respectively.
<u>Explanation:</u>
As the environmental conditions are deteriorating day by day, thus it is necessary to train to boost upcoming generation for preserving it in most appropriate manner. For such actions awareness is necessary which should be encouraged by some volunteers of non-profit organization, environment protecting units of state and central, etc to conduct seminar in colleges and schools for students to make them understand the need of plantation and disadvantages of deforestation. The pattern to aware them should be remarkable, in order to create huge impact on the new generations towards green land.
Persipitation and geographic layout
Answer:
1) To form a multicellular organism, a zygote must divide into 16 cells which produces ball structure called a morula. After that, morula is converted into a structure called blastula.
2) Adult stem cells are responsible for the maintenance of tissues and repair the damage tissues in the body. It is also called somatic stem tissue. It increase in number through cell division.
Answer: The genotype ratio is 2Ff : 2ff
The phenotype ratio is two normal feathered birds to two silky feathered birds.
Explanation: Let F represent the gene for normal feather and f represent the gene for silky feather. F is dominant while f is recessive, therefore a male that is hybrid for trait of normal feather is heterozygous and will have a genotype of Ff, a female that is homozygous for silky feather will have a genotype of ff.
A cross between Ff and ff will yield 2Ff birds and 2ff birds. Since F is dominant, a bird having genotype of Ff will manifest outwardly as blue feathered birds while ff will manifest outwardly as silky feathered birds because f is recessive and must occur in a homozygous condition in order to manifest phenotypically. Therefore, the genotype ratio is 2Ff: 2ff.
