Answer:
The correct answer to the question is Biofuel
Explanation:
Biofuel can be used as an alternative energy technology source to power a car.
The importance of using biofuel is that it causes less air pollution than fossil fuels, and it has less effect on the global warming. Most importantly, it is produced from agricultural sources.
The biofuels that can be used are butanol,ethanol and biodiesel etc.
Wind, geothermal and hydropower can not be directly used to provide power to the car.
Hence, the correct answer to the question is that biofuel which can be used as an alternating technology to provide power to car.
Answer:
On the basis of Chargaff's rule, in a double-helical DNA, A = T and G = C (Here A means adenine, T means thymine, G means guanine, and C means cytosine. For X, A is given 32%, therefore, T must be 32%, and the leftover 36% is to be distributed equally between G and C. Thus, G = C = 18% each.
The assumption formed is that the DNA is a double-stranded structure. The species that exhibits higher G + C content in the molecule of a DNA is steadier at higher temperatures as it melts at high temperature. The species Y, which exhibits G + C in total as 66% is the thermophilic bacterium between the two.
Answer:
(especially of a leaf or shell) having a round-toothed or scalloped edge
Explanation:
Answer:
The correct answer is
1. A rabbit living in a desert has long ears to disperse heat- abiotic factor.
2. A moth immediately dives to the ground when it hears a bat- biotic factor.
3. A lizard stays warm by sunning itself on a rock- abiotic factor.
4. A cactus has spines instead of leaves to help conserve water- abiotic factors.
5. A petunia is bright red to attract hummingbirds- biotic factor.
6. A stick-bug blends in with trees to hide from predators- biotic factor.
Explanation:-
The environment includes both abiotic and biotic factors which can affect the ecosystem. Living elements like plants and animals which affect ecosystem are known as biotic factors while the non-living elements which include air, water, temperature are called abiotic factors.
In the given question the options affected by the biotic factors due to bat, due to hummingbirds and due to predators.
Options affected by the abiotic factors due to heat and due to water.
