The more numbers of the homologous structure, the more likely they have recently shared a common ancestor.
Explanation:
Homologous organs are defined as those organs which do have different functions but a similar basic structure which denotes the divergent evolution. Homologous organs are seen in species that are very close to each other which are more related with each other in terms of evolution. For example, a bird is more close to each man than a fish, so do share more homologous organs common to man than fishes do. Examples of the homologous organs are hands of human and wings of birds. They have same basic structure like skeletal structure which is humerus, radius, ulna, carpals, metacarpals and phalanges. They are similar in structure but have different functions like flying in birds and gathering food in humans.
Answer: Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.
Umbilical cord and haploid
Answer:
Implantation, gestation, and birth. Reproductive patterns in placental mammals are diverse, but in all cases a secretory phase is present in the uterine cycle, and the endometrium is maintained by secretions of progesterone from the corpus luteum.

Answer:
(f - g)(x) = 2x - 3
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Explanation:
<u>Step 1: Define</u>
f(x) = 3x - 1
g(x) = x + 2
(f - g)(x) is f(x) - g(x)
<u>Step 2: Evaluate</u>
- Substitute: (f - g)(x) = 3x - 1 - (x + 2)
- Distribute -1: (f - g)(x) = 3x - 1 - x - 2
- Combine like terms: (f - g)(x) = 2x - 3
