Answer:

Gastrulation is the process where the developing embryo forms the process of the 3 germ layers. These germ layers are formed due to the movement of the single-layered blastula. Gastrulation starts during the third week of the human embryo.

The three germ layers give rise to different organs of the fetus. The 3 layers are ectoderm or outer layer, mesoderm or middle layer, and endoderm or inner layer.  

These 3 germ layers give rise to different organs of the human fetus. Ectoderm forms epidermis, skin, hair, olfactory organs, eye lense. glands like pituitary. Sensory nerves, skeleton, pigment cells are also formed from ectoderm.  

Ectoderm also forms a neural tube that further divides to form the brain, spinal cord.

Mesoderm form the vertebral column, skeletal muscle, excretory organs, reproductive organs. It also forms blood cells, blood vessels, body cavity or coelom.

The inner layer endoderm gives rise to the lining of the digestive tract, liver, pancreas, bladder, etc.

saul85 [17]
Based on the attached Image;
The two species that are likely to have the most similar DNA base sequences are C and D. 
An evolutionary tree or a phylogenetic tree, like the one shown on the image is used to indicate which ancestors gave rise to which descendants. The tree represents the evolutionary relationships among a set of organisms or groups of organisms, called taxa. The tips of the tree represents groups of descendant taxa and the nodes represents the common ancestors of these descendants.

ivanzaharov [21]

Answer:

<u><em>Galapagos finches</em></u><u> have various beak sizes that make foraging for food more successful.</u>

Explanation:

Organisms evolve over time due to changes in their genome. These are pontaneous, and occur in DNA at random. These changes are called mutations and form alleles or different forms of a gene.

Over time within a population, the number alleles increase the variation of the population. These variants may confer specific traits within an individual, that may confer a biological advantage.

Thus, the trait may make the organisms more capable of obtaining food, shelter a mate etc. or ensure survival, i.e. they are able to pass on their genes to the next generation.

Oksanka [162]
GM foods should be labeled in food stores. If, for example, someone wanted to buy a GM Apple, which could be enriched in chemicals, that should be labeled different than a regular apple. What if someone was allergic to some of the modifications in that apple. If there was a label on that apple, that person would not get a allergic reaction. That is why GM products should be labeled.
