Combustion is the burning of a substance. It could be complete or could be incomplete. It changes the form of carbon and so it plays it's role in cycle
Answer:
Kidneys
Explanation:
The kidneys remove wastes and excess water in the body through the urine, as urine flows from the kidneys to the bladder through two thin tubes located on both sides of the bladder called the ureter, and the bladder stores urine, and each of the kidneys consists of about one million filtering units called the renal tubular unit contains Each renal tubular unit has a filter called the glomerulus and tubule, and the renal tubular unit operates through a two-step process:
glomerulus: filters blood.
Tubule: Returns the necessary substances to the blood and removes waste.
The three observations that could help an individual in distinguising whether the organism is a fish or not is that it should live under water as fish can't survive without water, another thing is that it should laid eggs when it comes to giving birth because when it does not lay eggs but produces a living organism normally without an egg, it is considered to be a mammal and lastly, the appearance it possess such as having gils or fins.
<span>The female frog's reproductive system is consist of a pair of ovaries and a pair of oviducts. The ovaries are attached to the kidneys. The kidneys carry countless ova which are released to outside through the oviducts. </span><span>In the breeding season, the male and the female frogs enter into a temporary union called amplexus. The male holds the female, presses her trunk and thereby forces the female to release the eggs, the male frog then releases the sperms immediately to bring about exterior fertilization.</span>

The correct answer is explained below:</h2>
Explanation:
- According to the question, free ear lobes are dominant over attached ear lobes.
- Let the allele for free ear lobes be represented by F.
- Let the allele for attached ear lobes be represented by f.
- The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
- The gamete produced by the woman is: f.
- The genotype of the heterozygous man (father) with free earlobes is: Ff.
- The gametes produced by the man are: F and f.
- Mating the man with the woman we get the following offspring,
F f
f Ff ff
Phenotype Free ear lobe Attached ear lobe
- The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
- The probability that the parents would produce children with attached ear lobes is =
.
