Homologous structures are organisms which are grouped according to phylogeny, reveal that closely related organisms have more similar structures for example whales were once classified as a fish because they live in the water and they have flippers. Flippers are homologous to human arms and legs and they are therefore closely related to human beings.
Similar embryological development. Embryos of various vertebrates all look similar, including features. For example, tails which are not seen in the maturity suggests that all organisms evolved from a common ancestor, still, we express and share genes that are shared and belie ancestry.
Shared biochemical molecules such as DNA and ATP structure of molecules reflect descent with modification. The evidence of universal common ancestor is being reflected in the universality of DNA as a genetic material.
The genetic code in the machinery of DNA expression and replication. The relatedness within groups of organisms is reflected in the similarity in their DNA sequences. This is the exact pattern to be expected from diversification and descent from a common ancestor.
Answer:
Presence of chloroplast in plant cells
Explanation:
Chloroplast is an organelle found in the cytoplasm of plant cells, and helps in photosynthesis, by providing a site for trapping sun light which is used to produce food. Hence, plants are producers due to the presence of chloroplast while animals lack chloroplasts, so unable to produce their own food.
Thus, the presence of chloroplast in plant cells make it different from animal cells
Answer:
you would get sick time and time again
<span>d) The nucleus contains the instructions and passes those instructions to the ribososmes</span>
The 10<span>% </span>Rule<span> means that when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on. They play a big part in all food chains. Only 10% is passed and the rest is lost as heat.
I hope this helps!
