Why are biofuels derived from plants?

Biology
1 answer:
Lemur [1.5K]3 years ago
7 0

Answer:

Biofuels are renewable fuels that are produced from biomass, organisms that were formed and stopped living a short time ago. The energy in the biofuels is called bioenergy. The major constituents of biomass are cellulose, lignin, starch and sugar, but many plants also contain other organic compounds that are beneficial for energy recovery from the material due to their physical structure and chemical composition. The difference between biofuels and fossil fuels is that fossil fuels take millions of years for new formation while new biomass for biofuels is constantly being formed. This means that biofuels can usually be considered carbon neutral as the carbon dioxide emitted during combustion is constantly bound to new biomass in a closed cycle.

Which characteristic of living things is important to the survival of a group of animals rather than an individual member of thi
sammy [17]

Answer:

If a whole specie of organisms has to survive, they should must possess the ability to reproduce and adopt to environmental conditions in better way.

For example: If a disaster occurs or a condition of unfavorable weather occurs, the specie will survive even if only few members remain alive. Because those members will reproduce and regrow the community.

The reason is this that reproduction is not important for the survival of one organism, like organism will still survive even if he do not reproduce, but if a whole specie has to survive and continue, reproduction is most important trait.

Hope it help!

<span>The correct answers are that it lacks cells, DNA, and cannot maintain homeostasis. It doesn't have any organic matter and homeostasis is impossible because it would turn off eventually. It doens't have DNA and it doesn't reproduce. It's just plasma and it is not a living being, it just moves because of the chemical reactions that occur. </span>

These genes are 30 units apart on chromosome III. In this problem, you will calculate what crossing over in the female contribut
Damm [24]

Answer:

This exercise is incomplete. The response options are as follows:

a) e+ ca+

b) e ca

c) e ca+

d) e+ ca

The answer is c) e ca+ and d) e+ ca

Explanation:

The Punnett square is a diagram used by biologists to calculate the probability that an individual has a particular genotype. In the Punnett square, each of the possible combinations for the expression of the dominant and recessive alleles can be observed. In the case of exercise, since a crossing is not possible in men, these will only help later during the combination of the alleles.
