Answer: The statement is false
Explanation:
NONSENSE mutation, NOT MISSENSE mutation causes premature chain (protein) termination.
Missense mutation is simply a kind of point mutation where a single nucleotide is changed to cause substitution of a different amino acid, thus resulting in a non-functional protein.
So, non-functional protein is caused by missense mutation making the statement false

fossil fuels in the long run will end up destroying the earth, and we will run out of them. alternative fuels and energies are sustainable and can be used forever without harming the environment.
Answer:
prophase-division of somatic cells
for growth and repair of cells
prophase 1- division of gametes
contains homologous pairs
The cell would shrivel. This is due to the fact that it would lose water to the surrounding 2% sugar solution through osmosis. The surrounding sugar solution is more concentrated hence hypertonic compared to the cell solution of 1%. Water, in osmosis, moves from a hypotonic solution to a hypertonic solution, through a semipermiable, until an isotonic balance is achieved.
Answer:
Vascular plants are successful land plants. Spermatophyte (seed plants) is the largest group of vascular plants having two sub classes, angiosperms and gymnosperms. It include 300 families, 12500 genera and 300000 known species. The most successful and and important of these plants belong to Gramineae or the grass family with 7500 known species, which have colonized the great area of earth surface in particularly all sort of soil and climatic conditions and constitute the main source of man's food supply.
Factors responsible for success
1. Their adaptability to all kinds of environments.
2. The production of flowers, fruits and seeds, which show various adaptations for dispersal over large area.
3. These plants posses cuticle a thick cover around the epidermis which help in maintaining water or prevent dehydration.
4. Stomata are pesent in leaves or lenticle in stem which regulate the in and out of CO₂, O₂ and H₂O.
5. Well develop root system which help in absorption of mineral and other nutrients.
