I believe it that the answer is C. Hope this helps
Answer:
mitochondria: <u>powerhouse of the cell</u>
Ribosomes<u>: the places where proteins are synthesized in our cells. </u>
nucleus <u>houses DNA;controls cell</u>
Vacuole: <u>holds waste and fluids from cell</u>
Ribosomes: <u>tiny organelles that contain RNA and specific proteins within the cytoplasm. </u>
Explanation:
Organelles make up the subunits of a cell. There are numerous each with their own function.
Answer:
B. 100 percent yellow seeds
Explanation:
When a gene has two alleles and one allele is dominant over the other, the dominant allele is expressed in the heterozygous state and the expression of the recessive allele is masked. According to the given information, the allele for yellow seed color is dominant over the allele for the green seed color.
Let's assume that the allele "Y" gives yellow color to the seeds while the allele "y" is responsible for green seed color. A cross between two pure breeding yellow seeded (YY) and green seeded (yy) plants would produce all the yellow seeded progeny with genotype "Yy".
YY (Yellow) x yy (green) = Yy (yellow)
The right answer is facilitated diffusion.
Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.
