Answer:
I would write "terrestrial/lives on land during all life stages" between the frog and pigeon branches.
Explanation:
Jaw evolution has started with fish, so i'd place that before the perch, evolution of four limbs is next and I would plate it between the perch and the frog. Evolution of an egg has ensured that organisms remain terrestrial during all stages of life and don't need to rely on water to lay their eggs. So I would place that between the frog and the pigeon. True mammary glands and true hair, as we know it formed on mammals so i'd place that between the pigeon and the rats (although synapsids evolved similar structures long before birds even existed). And lastly, I would place "walking on two legs" between rats and human branches. Because our ancestors evolved bipedalism relatively late.
Answer:
Xylem and Phloem tissues are present throughout the plant. They begin at the root and then move up to the stem, branches, and leaves. The xylem tissue transports water and minerals from the roots to the leaves whereas the phloem tissue transports food from the leaves to the other parts of the plant
Explanation:
<u>In law of superposition which layer is the oldest and which layer is the youngest?</u>
Law of superpostion is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy. In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. The oldest layer would be at the bottem because of how old it is and because of how much other elemnt has been coverd on it. The younges would be on top because it is newer and just got the in the last 100 years.

Answer:
A) birds have a large opening where the beak should be.
Explanation:
when scientists turn off the gene that makes beaks in birds, the birds have a mouth where no teeth are present. The birds have mouth because the bird resembles and closely related to the dinosaur. There are some proteins that is responsible for the occurrence of beak but when the genes are turn off these protein stop producing that leads to turn the beak place into mouth.
