a. yeast lacks a cell membrane. an onion skin cell has a cell membrane.
b. yeast doesn't have a cell wall. the onion skin cell has a cell wall.
c. yeast has chloroplasts. the onion skin cell doesn't have chloroplasts.
d. yeast lacks a membrane-bound nucleus. the onion skin cell has one

Answer;

B. Yeast doesn't have a cell wall. The onion skin cell has a cell wall.

Explanation;

-An onion is a multicellular (consisting of many cells) plant organism.As in all plant cells, the cell of an onion peel consists of a cell wall, cell membrane, cytoplasm, nucleus and a large vacuole. The nucleus is present at the periphery of the cytoplasm.

-The vacuole is prominent and present at the center of the cell. It is surrounded by cytoplasm. The presence of a cell wall and a large vacuole are indicators that help identify plant cells, such as seen in the onion peel.

Like bacterial cells, yeast cells have cytoplasm and a membrane surrounded by a cell wall that lacks cellulose, like those of plants.  Yeast cells have a nucleus.They are smaller than animal and plant cells, but slightly larger than bacteria.  

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.

there is not 1 highest source of protein, but there are many; meats, fish, poultry, seafood, cheese, eggs, yogurt and milk. the only non complete animal food that is beneficial is gelatin.

sorry if this did not , have a great day!
