It had gills, scales and fins, but also had tetrapod-like features such as a mobile neck, robust ribcage and primitive lungs
Explanation:
The mitochondrion is a membrane-bound organelle that provides energy by ATP synthesis (oxidative phosphorylation)
The lysosome contains about 40 hydrolytic enzymes that help with cellular digestion.
The Golgi apparatus plays an important role in the excretion and packaging of vesicles.
A)
Therefore:Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).
b)
Therefore:Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).
c)
Therefore:Crossing results in 100% (homozygous recessive).
Explanation:
Each part of your digestive system helps to move food and liquid through your GI track, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool.
The most likely explanation for the variation is the offspring were produced from different combination of genes. A single pair of gold fish mentioned in the question means a male and a female gold fish. The two of them mated and contributed different genes to the fertilized fish eggs, this results in production of various body shape and colouration which is known as variation.
