Answer:
The correct answer would be Option C, Multipurpose Trees.
Explanation:
With the advancement in industries and other areas of technology, the rural areas have become so much polluted. So the sustainability of the rural areas is doubtful. The air in the rural areas have become polluted and needs measures to prevent it from harmful consequences of the industrial advancements. Along with industries, the air pollution is also added through vehicles discharge, waste disposal, etc also contribute towards the non sustainability of the rural areas. So to overcome all these problems, the best solution is to grow the multipurpose trees in the rural areas as much as possible to increase the sustainability of these areas. With the plantation of trees, the problem of pollution will be controlled and thus make these areas sustainable.
Answer:
Alternation of generation with both sexual and asexual
Explanation:
In mosses, the dominant plant is called a gametophyte while in ferm the dominant is sporophyte. Gametes are produced by the gametophyte and fertilization occurs forming an embryo. The embryo develops into a plant called the sporophyte.
Answer:
a. an example of a transgenic tomato (also called GMO tomato)
Explanation:
Genetic modification is the process by which an organim's genome is manipulated in order to achieve a desirable feature in such organism. Also called genetic engineering, genetic modification involves using biotechnology to alter an organims genetic composition. The organism whose genome is manipulated is called GENETICALLY MODIFIED ORGANISM (GMO) or TRANSGENIC ORGANISM.
In this case, a tomato with a gene from a fish that helps the tomato resist frost damage is said to be an example of GMO or transgenic organism because the genome of the tomato plant has been manipulated by inserting a desirable gene (resistance to frost) into it.
Answer:
2.23 atoms
Explanation:
In this question, we first need to change the mass of Nitrogen to moles by using the formula;
mole = mass ÷ molar mass
Molar mass of Nitrogen = 14g/mol
Mass = 5.2x10^-23 grams
mole = 5.2x10^-23 ÷ 14
mole = 0.371 × 10^-23
mole = 3.71 × 10^-24 mol
Number of atoms in Nitrogen atom = 3.71 × 10^-24 mol × 6.02 × 10^23 atoms (avagadro constant)
= 22.3342 × 10^(-24+23)
= 22.33 × 10-¹
= 2.233 × 10°
= 2.23 atoms
Winds drive currents near coastal areas on a localized scale, and in the open ocean on a global scale. A third factor that drives currents is thermohaline circulation - a process driven by density differences in water due to temperature (thermo) and salinity (haline) in different parts of the ocean.
