AleksandrR [38]
<span>The most appropriate response would be for the nurse to ask the patient about their current concerns. This allows for the patient to actually elucidate what he or she is feeling at the time and does not hamstring the provider into actually giving a set length of time that they feel the patient has left to live, which can vary greatly from person to person.</span>

Jenny predicts that when water in a cup evaporates, the mass of the water and cup together will get smaller.
Elden [556K]

A.  Use a scale to measure the mass of a cup of water. Leave the cup out for one day and measure the mass again.

Explanation:

Jenny can predict is evaporation occurs by using a weighing scale to measure that mass of a cup of water, then he leaves the cup out for one day and he measures the mass again.

  • If the mass remains the same, then evaporation did not occur.
  • If evaporation occurs, then the mass will be lesser after the second measurement.
  • From this Jenny can infer the mass loss and made good deductions.
  • Evaporation is a phase change in which liquid turns to vapor.

Give the function of all of the following parts of a typical flower. a. Petals
maxonik [38]

A.Petals. Usually, petals are the most prominent part of a flower structure, owing to their vivid color (in most flower examples) and sometimes scent. Their main function is to attract pollinators and also protect the inner reproductive structures of a flower. In some flowers, petals are absent or reduced.

B.Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.

C.Pistil interaction precedes fertilization in the flower. Important changes occur in the pistil, which play a role supporting, but also controlling pollen-tube growth

D. The ovule is the organ that forms the seeds of flowering plants. It is borne in the ovary of the flower and consists of nucellus protected by integuments, precursors of embryo/endosperm, and seed coat, respectively.
