Answer:
Two recessive genes for attached earlobes
Explanation:
For a recessive trait to be displayed, it must mean that the individual does not possess a dominant allele that would be expressed instead of the recessive allele. Therefore, Ashley must have two copies of the recessive genes to have attached earlobes. Possessing one or two dominant genes for free earlobes would mean that she would have free earlobes.
This can also be visualised with a punnet square, see attached image. We know the parents carry a recessive allele but have free earlobes, so they must have the genotype Ff. The punnet square shows 3 genotypes are possible
FF, which would give free ear lobes
Ff, the same genotype as her parents, free earlobes
and ff, which would give attached earlobes.
Electromagnetic fields and therefore waves are generated orthogonal to the electric current that generated it.
First question:
a. Gastrulation
Gastrulation is a phase<span> of the </span>embryonic development<span> in </span>animals. It doesn't occur in plants or any other organism. The other options can be put apart because <span>multicellularity, sexual reproduction, and </span>flagellated sperm are also characteristics that are present in plants, for example. Heterotrophic nutrition is something that's part of all <span>animals as well as non green plants.
Second question:
a. M</span><span>ulticellularity
</span>Synapomorphy is <span>a shared </span>trait <span>that distinguishes a </span>clade<span> from other organisms. C</span>hoanoflagellates are considered the most close ancestors to the animals distinguishing from them by multicellularity. They are very studied with the purpose to know the mechanisms of colonies' formation and evolution to multicellular animals.
Third question:
<span>d. Choanoflagellates
This are the most closely related living protist group. The </span>choanoflagellates are very similar to the ch<span>oanocytes of the sponges bringing them into closeness with the animals. They even aggregate in colonies, and are thought, because of all of this, to be the closest branch of single cells to that of the animals.</span>
The otoliths are small calcium carbonate crystals which put pressure on the cilia, inclining them, thereby stimulating the sensory hair cells.
They can cause problems for your health such as dizziness and vertigo
