Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.

What is digested in the small intestine including the nutrients, substance, enzyme and final product of the thing being digested
inn [45]

Answer:

The pancreas and gland cells of the small intestine secrete digestive enzymes that chemically break down complex food molecules into simpler ones. or Complete digestion takes place in the small intestine as it finally absorbs the nutrients. The end products of digestion are amino acids, fatty acids, glycerol, and glucose.

Explanation:

If you're talking about the end product go with the latter

Katie has a rare neurological disease in which her neurons can receive new information and process it, but some of them just can
Wittaler [7]

Katie has a rare neurological disease in which her neurons can receive new information and process it, but some of them just cannot pass the information along. This disease most likely affects the axon of the neurons. Since axon is the signal transmitting end of the neuron, if the fusion of the vesicles containing the neurotransmitters with the cell membrane around the synaptic cleft is hampered, then the signal transmission gets disrupted.

Question 6 You cross a true-breeding red-flowered snapdragon with a true-breeding white-flowered one. All of the FI are pink. Wh
muminat

Answer:

E (Red shows incomplete dominance over white)

Explanation:

This portrays a monohybrid cross involving a single gene coding for flower colour in snapdragon plants. According to the question, a purebreeding red flowered (homozygous) plant is crossed with a purebreeding white flowered (homozygous) plant to produce an all pink flowered offspring. This phenomenon is called INCOMPLETE DOMINANCE.

Mendel, in his experiments, discovered that an allele can mask the expression of another in a heterozygous state. He called the allele that masks DOMINANT allele while the allele that is masked RECESSIVE allele. However, exceptions like INCOMPLETE DOMINANCE, has occurred in the sense that an allele does not completely mask the expression of its allelic pair, instead an intermediate phenotype, which is a combination/blending of both parental phenotypes is produced.

In this case, the red flowered snapdragon (RR) does not completely cover up the expression of white flower (rr), hence a hybrid/heterozygous offspring is produced that combines the phenotypic characteristics of both parents to form an intermediate flower colour (pink). Hence, it can be said that Red flower is incompletely dominant over white flower or no allele/trait is dominant or recessive to another.
