The genetic material that children inherit from their parents and the physical similarities of children to their parents are the evidence for evolution. Comparative anatomy is used to show relatedness from generation to generation by having similar DNA sequences or patterns and traits.

Answer:

Homologies and vestigial structures are two evidences of the evolution of how DNA and comparative anatomy used to show relatedness

Explanation:

Living organisms have characteristics that make them similar to others, which may suggest that at some point in the history of life on Earth, they shared a common ancestor. When we look at the limbs of a crocodile and a rat, for example, we find that, despite their differences in morphology, they are quite similar in anatomy, suggesting that they may be related. In this case, we say that the characteristic is homologous, that is, it has a similar embryonic origin, but it does not always perform the same function.

Trace structures are structures that are atrophied and have no apparent function in an organism. The presence of these organs can be interpreted as evidence of evolution, since the structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.

Where does ocean expansion even occur? What place/country.

Most people affected would live in China: 43 million or around 20 percent. At 32 million and 27 million affected people, Bangladesh and India would also be hit hard, as would be Vietnam, Indonesia, Thailand, the Philippines and Japan. In Europe, the Netherlands would theoretically be the most affected.

Sunny_sXe [5.5K]

Answer:

a vestigial structure

Explanation:

Vestigial structures are a rudimentary (or even functionless) version of a body part, but they have important functions in a closely correlated or evolutionarily close species, an example of which is the presence of eyes in fish of the genus Astyanax. The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.

What are the three substances that generally make up paint? describe each part. what are polymers? what is a scanning electron m

pochemuha

The three parts that make up paint are pigments, binders and solvents. Pigments consist generally of organic and non-organic compounds and materials that are added to paint to produce a particular color. Binders are substances that provide support or structure for the pigment and solvents to work. Solvents work to dissolve or disperse these substances into liquid form.
Polymers are a group of atoms that form in repetitious patterns The scanning electron microscope is a microscope that works by shooting beams of electrons at the slide and recording the emissions of the electrons. One advantage is that it has much better magnification than other microscopes

Endosymbiosis of cyanobacteria is widely accepted as an explanation for the development of chloroplasts. The presence of endosym

lilavasa [31]

Answer:

The correct answer is- photosynthesis

Explanation:

According to the endosymbiotic theory, an ancestral cell engulfed a cyanobacteria and lived in symbiotic association with that bacteria and over time this bacteria evolved into the chloroplast and the ancestral cell developed into plant cell.

So as cyanobacteria was the first aerobic cell that can evolve oxygen and can do photosynthesis to produce organic food so it could be concluded that the presence of endosymbiotic cyanobacteria provided a cell with the advantage of photosynthesis.
