The principle fuel used as a petrol substitute for road transport vehicles is bioethanol. Bioethanol fuel is mainly produced by the sugar fermentation process, although it can also be manufactured by the chemical process of reacting ethylene with steam.
Basically, a plant can be considered as bioethanol becacuse it is a sugar fuel for animals. Animals consume plants for fuel to survive.
Answer:
The correct answer is luteinizing hormone.
Explanation:
Hypothalamus has two sets of nerve cells that produce hormones. One set sends the hormones that are anti-diuretic hormone and oxytocin. ADH regulates or water in the bloodstream by reabsorption of water at the kidney and oxytocin helps in pregnancy and breastfeeding.
The other set produces hormones growth regulating, stress releasing and stimulating and inhibiting hormones are dopamine, corticotrophin-releasing hormone, growth hormone-releasing hormone, gonadotropin-releasing hormone, somatostatin, and thyrotropin-releasing hormone.
Luteinizing hormone is secreted by the pituitary gland. It is one of the main hormones that control the reproductive system.
Thus, the correct answer is luteinizing hormone.

Answer:
The stigma, a female structure which collects pollen and passes it to the ovary
Explanation:
<u>The structure represented by the letter A in the diagram is the stigma.</u>
The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.
<em>The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.</em>
