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.

Why grapes swell when placed in water
scoray [572]

When grapes are soaked in water, the grapes then swell up because grape's cells have a high concentration of solutes in comparison to the water. In other words, grapes have low concentration of solvent (that is water molecules ) in comparison to the concentration of solvent in water. In this situation, there will happen a process known as osmosis in which water molecules moves from a region of concentration of water to a region of low concentration of water through a semipermeable membrane. (the cell membrane of the grape's cell is also semipermeable,which only allows solvent molecules to pass through it)

Describe how you think a child’s DNA is different from his or her mother’s DNA and father’s DNA.
monitta

Answer:

  • For starters, you inherit two copies of each chromosome—one copy from your mom and one copy from your dad. <u>This means that your genome (all of your DNA) is already different because it contains chromosomes from both of your parents</u>.

  • So yes, it is definitely possible for two siblings to get pretty different ancestry results from a DNA test. Even when they share the same parents. DNA isn't passed down from generation to generation in a single block. Not every child gets the same <u>50</u>% of mom's DNA and <u>50</u>% of dad's DNA.

  • DNA is passed down to the next generation in big chunks called chromosomes. Every generation, each parent passes half their chromosomes to their child. If nothing happened to the chromosomes between generations, then there would be around <u>a 1 in 8 chance</u> that you would get no DNA from a great, great, great grandparent.

  • Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your <u>mother.19DNA</u> is the material that carries all the information about how a living thing will look and function. For instance, DNA in humans determines such things as what color the eyes are and how the lungs work. Each piece of information is carried on a different section of the DNA. These sections are called genes.

  • Each son receives DNA for his Y chromosome from his father. This DNA is not mixed with that of the mother, and it is identical to that of the father, unless a mutation occurs. It has been estimated that a mutation occurs about once every <u>500</u> generations, or every <u>15,000</u> years, give or take a few millennia.

  • DNA Paternity tests can falsely exclude someone who is truly the child's biological father for a variety of reasons. One major reason is simple human error.

  • While women do inherit <u>50</u>% of their DNA from each parent, men inherit about <u>51</u>% from their mother and only <u>49</u>% from their father.

<h2>1986</h2>
  • In <u>1986</u> was when DNA was first used in a criminal investigation by Dr. Jeffreys. <u>1986</u>. The investigation used genetic fingerprinting in a case of two rapes and murders that had happened in <u>1983 and 1986.</u>
