An organism's development from an embryo may contain clues about its history that scientists can use to develop relationships an

d build evolutionary trees. Ancestral characters are often preserved in an organism's developmental stages. For example, both bird and human embryos go through a stage where they have slits and arches in their necks like the gill slits and gill arches of fish. These structures are not gills and do not develop into gills in birds and humans, but because they are so similar to gill structures in fish at this point in development scientists believe that A) birds and humans evolved from fish. B) all vertebrate animals have identical embryos. Reactivate C) fish, birds, and humans share a common ancestor. D) fish evolved as a life form long before birds or humans.

<h2>Answer is option "C"</h2>

Explanation:

  • The way that these formative highlights are so like the gill structures in fish bolsters that fish, chicks, and people share a typical predecessor
  • Ancestral characters are regularly, however not constantly, safeguarded in a life form's improvement. For example, both chick and human early creatures experience a stage where they have cuts and bends in their necks like the gill cuts and gill bends of fish
  • These structures are not gills and don't shape into gills in chicks and individuals, be that as it may, how they are so similar to gill structures in fish currently being created support that chicks and individuals share a run of the mill ancestor with fish. Subsequently, formative characters, alongside different lines of proof, can be utilized for developing phylogenies
  • Hence, the right answer is option C "fish, birds, and humans share a common ancestor"

A florist assembles a bouquet of flowers from the following: 1. lilies, which have long leaves with parallel veins 2. Queen Anne
fomenos

Answer:

C) three eudicots and one monocot.

Explanation:

Flowering plants are generally divided into two based on the number of seed leaves. These are:

  • Monocots: <em>these are flowering plants with only one seed leaf. Their leaves are usually long and narrow with parallel veination. Seed germination mode is hypogeal. Their stems are usually flesh and without branches and their roots are usually fibrous. Monocots' flowers are usually trimerous, that is, the flower parts are usually in threes.</em>
  • Eudicots: <em>as opposed to monocots, they are flowering plants with two seed leaves. The mode of seed germination is epigeal, leaves are usually broad with net veination pattern and they posses tap root system. Flower parts are usually in fours of fives and their stems are usually wide with branches.</em>

Let us look at which of the 2 groups the bunch of flowers collected by the florist belong:

Lilies have parallel vein - monocot

Wild carrot has large taproot - eudicot

Buttercups has five petals - eudicot

Daisies with two cotyledons - eudicot.

<em>Hence, the bunch of flowers contain three eudicots and one monocot.</em>

The correct option is C.
