The answer is A. anther and ovary.

The female part of an angiosperm flower is called a pistil and it consists of a style, stigma and ovary. The male part of an angiosperm flower is called a stamen and it consists of an anther and corolla. Thus, among all choices, choice A is the answer.

Choice B - anther is the male part of the flower, but sepal is a protective part of the flower and not reproductive.

Choice D - stigma is the female part of the flower, but sepal is a protective part of the flower and not reproductive.

Choice C - "vary" is not a word, but it is a mistake and it should be "ovary,"  the answers could be both choice A and C.

The highest level of Bloom's taxonomy is __________, which is defined as using your ability to judge the value of ideas and info
Kobotan [32]

Answer:

Evaluation.

Explanation:

The evaluation stage in Bloom's Taxonomy is where students make a judgment about the importance of concepts, objects, materials and more. Knowledge, comprehension, implementation, examination, synthesis, and evaluation were the main sequence of cognitive skills. Evaluation is the final stage of Bloom's pyramid taxonomy. It is at this stage that students are expected to put together all they have learned to make content assessments. However, it should be noted here that in 2001, synthesis has been removed and creation is added as the highest stage of Bloom's taxonomy.

Archaefructus, an early fossil angiosperm, was herbaceous and probably aquatic. Other seed plant fossils were woody and terrestr
Ludmilka [50]

The scientists should conclude that other data must be considered in order to make a valid conclusion.

<h3>What is Archaefructus?</h3>

Archaefructus is an extinct genus of herbaceous aquatic seed plants with three known species. Fossil material assigned to this genus originates from the Yixian Formation in northeastern China, originally dated as late Jurassic but now thought to be approximately 125 million years old, or early Cretaceous in age.

Even with its revised age, Archaefructus has been proposed to be one of the earliest known genera of flowering plants.

Because of its age, lack of sepals and petals, and the fact that its reproductive organs (carpels and stamens), are produced on an elongate stem rather than condensed into a flower as in modern angiosperms,

Archaefructaceae has been proposed as a new basal angiosperm family.

An alternative interpretation of the same fossil, however, interprets the elongate stem as an inflorescence rather than a flower, with staminate (male) flowers below and pistillate (female) flower above.

Why don’t free amino acids have peptide bonds? What is a free amino acid exactly?
slega [8]

Explanation:

Free amino acid do not have a peptide bond , as the amino acid act as a monomer which multiplies and linked via peptide bond to generate protein chain .

A free amino acid have a carbonly group (- COOH ) and a -NH₂ group .

The formation of protein chain require at least two amino acids linked via peptide chain .

The role of peptide chain only comes in case of protein , because it acts as a linking species .

Hence , free amino acid does not have any peptide chain .
