Answer:
Pros of Biofuels
Renewable – Biofuels are produced from plants and other organic material, so it can be replenished constantly. This is in contrast to the fossil fuels, which are constantly in the process of being depleted.
Clean – Biofuels are environment-friendly. They are much efficient & cleaner than fossil fuels, producing less air pollution and using materials that would otherwise be considered as waste products. Biofuels cause much less greenhouse gas emissions in comparison to the conventional types of transport fuels.
Inexpensive – They can be made easily by using local materials. Biofuels are very cheap to afford. They are the cheapest types of fuels available in the world.
Flexible – can be easily mixed with other fuels.
Additives – Biofuels like ethanol and biodiesel are better for car engines than fossil fuels. Even if not being used as the main fuel source, they can be used as additives to improve performance.
Carbon neutral – the amount of carbon dioxide created by the burning of biofuels is equal to the CO2 absorption capacity of the plants. Hence, no extra CO2 remains in the atmosphere.

Waste products may be stored in leaves that fall off.
Explanation:
Identical twins may have less in common than they think. A study now shows that the expression of their genes gets more and more different with age.
The findings could help to explain why one twin may develop a genetically influenced disease, such as diabetes, while the other remains perfectly healthy.
Identical twins have identical genes, because they are born of an embryo that splits at a very early stage in development. Such twins are often indistinguishable in outward appearance. But over the course of time they may experience radically dissimilar health.
Most scientists have assumed that environmental and lifestyle differences cause such divergence. These things trigger chemical reactions that affect our DNA and the proteins entwined with our DNA, called histones. One such reaction, known as methylation, influences the expression of genes and so can have an impact on health.
Answer:
The type of anemia seen in severe folate deficiency is characterized by large and immature blood cells. This type of anemia is called ____megaloblastic _, _____ anemia.
Explanation:
Anemia appears when the amount of red blood cells in the body decreases, more precisely the amount of hemoglobin contained in them. There are different types of anemia, including iron deficiency (iron deficiency), megaloblastic (vitamin B12 or folate deficiency). In this last type, the red blood cells become larger (macrocytic) from there the term megaloblastic. It occurs in this case by having hypovitaminosis, a defect in the synthesis of DNA. Some of the symptoms are: tiredness, fatigue, paleness, headaches, paleness, shortness of breath, among others.
Animals will migrate to other regions in search of food and the new species will evolve to survive int he deforested land.
