Answer: so, i only know number 6 which is human fertilization

Answer: 6. when sperm and eggs combine its called a zygote.

7. The diploid number for humans is 46 chromosomes. The haploid number is 23 or n=23.

8. Matching chromosomes are called homologous pairs.

9. During prophase 1 of meiosis these pairs form a tetrad process called crossing over or recombination.

10. When homologous chromosomes exchange genes it's called synapsis.

11. 2 daughter cells are created at the end of meiosis 1 and 4 are created at the end of meiosis 11.

12. During the meiosis chromosomes will split into daughter cells randomly making each gamete unique this is called Cytokinesis.

13. The process by which sperm is made is called Sertoli cells.

14. The process by which eggs are made is called oogenesis.

15. During the creation of an oocyte, 3 additional haploids are created that will not be fertilized these cells are called Polar bodies.

Jake's mom is making peanut butter cookies with chocolate chips. In her first batch, she used the ratio of 2:2 for the number of ups of chocolate chips to the number of cups of peanut butter chips. In her second batch, she used a ratio of 3:1 for the number of cups of chocolate chips to the number of cups of peanut butter chips and made the same number of cookies as the first batch. Jake made the following tape diagrams for his mom to reference. If her first batch used 4 cups of peanut butter chips, how many cups of chocolate chips did Jake's mom use for the second batch?

Answers

I think it’s 6 cups of chocolate chips.

Explanation:
If in the first batch the ratio of 2 is 4 cups, that means that the ratio 1 would be 2 cups. In the second batch, the chocolate chip ratio was 3, so it would be 6 cups. I hope this helps!!!

What is 6 3/4 divided by 2 5/8?

Answers

Conversion a mixed number 6 3/4 to a improper fraction: 6 3/4 = 6 3/4 = 6 · 4 + 3/4 = 24 + 3/4 = 27/4.

To find new numerator:

Multiply the whole number 6 by the denominator 4. Whole number 6 equally 6 * 4/4 = 24/4

Add the answer from previous step 24 to the numerator 3. New numerator is 24 + 3 = 27

Write a previous answer (new numerator 27) over the denominator 4.

Six and three quarters is twenty-seven quarters

Conversion a mixed number 2 5/8

to a improper fraction: 2 5/8 = 2 5/8 = 2 · 8 + 5/8 = 16 + 5/8 = 21/8

To find new numerator:

Multiply the whole number 2 by the denominator 8. Whole number 2 equally 2 * 8/8 = 16/8

Add the answer from previous step 16 to the numerator 5. New numerator is 16 + 5 = 21.

Write a previous answer (new numerator 21) over the denominator 8.

Two and five eighths is twenty-one eighths

Divide: 27/4 : 21/8 = 27/4 · 8/21 = 27 · 8/4 · 21 = 216/84 = 12 · 18 /12 · 7 = 18/7

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 21/

8 is 8/21) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 12 gives 18/7.

In words - twenty-seven quarters divided by twenty-one eighths = eighteen sevenths.

The solution of the expression [tex]6 \dfrac{3}{4}[/tex] divided by [tex]2 \dfrac{5}{8}[/tex] , which are in mixed fraction is [tex]\dfrac{18}{7}[/tex]

A collection of constants, variables connected using one or more arithmetic operator is called an expression.

The combination of a whole number and a proper fraction is called as mixed fraction.

The following expression can be simplified as:

Here, both the fraction are converted into improper fraction as[tex]\dfrac{27}{4}[/tex] and, [tex]\dfrac{21}{8}[/tex]

Now, the following expression is simplified as:

[tex]\dfrac{\dfrac{27}{4}}{\dfrac{21}{8}}[/tex],

Reciprocal the expression, so that the division sign changes to multiplication.

[tex]\dfrac{27}{4} \times \dfrac{8}{21}[/tex]

Thus, the solution will be [tex]\dfrac{18}{7}[/tex].

I want to say thank for helping me

Given:

3x(x - 2) + 2 and 2x² + 3x -12

If x = 7 then,

= 3(7)(7 - 2) + 2

= 21(5) + 2

= 107

= 2(7)² + 3(7) -12

= 2(49) + 21 -12

= 98 + 9

= 107

For x = 7, each expression has a value of 107.

If x = 2 then,

= 3(2)(2 - 2) + 2

= 6(0) + 2

= 2

= 2(2)² + 3(2) -12

= 2(4) + 6 -12

= 8 - 6

= 2

For x = 2, each expression has a value of 2.

These results suggests that the expressions are equivalent, but (I don't know the choices) the expressions are equivalent.

If Josh can read 18 pages in 40 minutes, how long will it take him to read 90 pages?

Answers

Answer:

18=40

90? 40×90=3600÷18=200 pages.

Answer:

It will take him 200 minutes to read 90 pages.

Step-by-step explanation:

Josh can read 18 pages in 40 minutes.

Ratio of pages to minutes = 18 : 40

Number of pages to read = 90

Minutes = x

Ratio of pages to minutes = 90 : x

The relationship is proportional

18 : 40 :: 90 : x

Product of extremes = Product of means

18x = 40*90

18x = 3600

Dividing both sides by 18

[tex]\frac{18x}{18}=\frac{3600}{18}[/tex]

x = 200

Therefore,

It will take him 200 minutes to read 90 pages.
