Answer:It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

Answer:
The correct answer is - 25,00,000 Kcal
Explanation:
The transfer of energy in the trophic level is move with each successive level of the trophic level of the pyramid. Energy transfer takes place in a manner that only 10% of the available energy move to the next level and the rest 90% of energy lost as heat and other processes.
So ith producers produce 25000000 Kcal than only 10 % of this will transfer to the next level or the second level of the pyramid
Producer ----> primary consumer ----> secondary consumer
100% energy 10% energy of producer 10% of primary consumer
So, the 10% of 25000000 -----> 2500000
Answer:
1) per capita paper consumed is determined by dividing total paper consumped by population
A) Africa ; population is 1136 x 106 and total paper consumed is 8 x 106 x 103 (here 106 is for million and 103 is kg for one metric ton)
=( 8 x 106 x 103 ) /1136 x 106
= 7. 04 kg
= 15. 52 pounds
B) Asia : by using above strategy we get,
= 96. 25 pounds
C) Europe :
= 273. 70 pounds
D) Latin America :
= 96. 29 pounds
E) North America :
= 474. 63 pounds
F) Oceania :
=226. 10 pounds
G)world :
= 121. 82 pounds.
Explanation:
Answer: Meiosis is the necessary process for the inherited traits of an organism to be passed along by sexual reproduction to bring about variation.
Explanation: Meiosis occurs in reproductive cells. It halves the chromosome number of parents to produce same (constant) number of chromosomes in the offsprings.
Meiosis leads to genetic variation among offsprings through recombination, crossing over, independent assortment and reduction and fusion of gametes.
Most abnormalities that are heritable are as a result of improper division during meiosis.
The inter-tidal zone refers to an area that is under water during a high tide and exposed to the air at low tides. Organisms living in the inter-tidal zone must be adapted to living in an extreme environment. They must be able to survive for sometime without water and in water that can be high or low in salinity. The nearshore zone is always under water and is the area where waves can break in their approach to the shore. Organisms here are adapted to living completely submerged in water.
