Like gymnosperms, many grasses and angiosperm trees are wind-pollinated. To conserve energy, these angiosperms do not produce complete flowers (complete flowers have all four of the basic parts). Which part would be unnecessary for wind-pollinated angiosperms?

C. petals

Explanation:

A)fruits

B)sepals

C)petals

D)anthers

E)ovaries

The part that will not be necessary in wind pollinated angiosperm is the petals .

The petal is a part of flower that is usually colorful and primarily function by attaracting insect pollinators to the flower.

Since wind pollinated angiosperms do not need to attract insect for pollination, they do not need the colorful petals. They rely on wind to carry their pollen from their anthers to their stigmas (pollination).

Hence, the correct option is C.

b, acidosis

acidosis is when the human body attempts to return the bloods ph levels back to normal when the blood is acidic

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
