What organelles contain vesicles?
aev [14]

Vesicles are used to ship materials around, into, and out of the cell. Cell membranes can pinch off in places to form vesicles, as can lysosome membranes and golgi membranes. Because mitochondria and chloroplasts are practically tiny cells within cells, I wouldn't be surprised if they had their own vesicles. If you're asking literally which organelles have vesicles inside them, I'd say the mitochondria and chloroplasts, possibly Golgi (depends on your instructor), but the cell membrane, lysosomes, and golgi can definitely make vesicles. The rough ER uses vesicles but I wouldn't consider the vesicles a part of the ER.

What are Medel’s THREE Laws of inheritance? please explain any one of these laws
DerKrebs [107]

<h2><em>The law of segragation, the law of independent assortment, and the law of dominance.</em></h2>

1) The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells in order that sex cells contain only 1 gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.

2) The Law of Independent Assortment: Genes for various traits are sorted separately from each other in order that the inheritance of 1 trait isn't smitten by the inheritance of another.

3) The Law of Dominance: An organism with alternate types of a gene will express the shape that's dominant.

The area of triangle LMN is 18 ft2 and the area of FGH is 24 ft2. If triangle LMN is equivalent to triangle FGH, what is the rat
Sedaia [141]

Answer:  Option 'C' is correct.

Explanation:

Since we have given that

Area of triangle LMN = 18 ft²

Area of triangle FGH = 24 ft²

Since Δ LMN and ΔFGH is equivalent triangles.

As we know the theorem which states that ratio of areas of equivalent triangles is equal to square of ratio of corresponding sides.

So, it becomes,

\dfrac{\Delta LMN}{\Delta FGH}=(\dfrac{LM}{FG})^2\\\\\dfrac{18}{24}=(\dfrac{LM}{FG})^2\\\\\dfrac{3}{4}=(\dfrac{LM}{FG})^2\\\\\sqrt{\dfrac{3}{4}}=\dfrac{LM}{FG}\\\\\dfrac{\sqrt{3}}{2}=\dfrac{LM}{FG}

Hence, Option 'C' is correct.
