How is it possible for a baby to grow all of its<br> organs
avanturin [10]

Explanation:

during the embryonic stage the baby grows its organs

Nervous system. This is one of the first things that develop. It includes the formation of the baby’s brain, spinal cord, and nerves.

Heart. An S-shaped tube forms on the front of the embryo. This will become the baby’s heart. At first the heart does not beat, but soon it starts beating and pumping an early form of blood.

Face. The baby’s facial features begin to take shape. The eyes and ears form. The eyes move forward on the face, and eyelids form. Pieces of tissue grow and join together to create the forehead, nose, cheeks, lips, and jaw. The nasal passages, mouth, and tooth buds form the baby’s first teeth. A tongue with taste buds also forms.

Arms and legs. At first, the baby’s arms and legs begin as little buds that sprout from the embryo’s sides. As they grow, the arms look like paddles and the legs look like flippers. A ridge appears on the end of each one. They eventually become the baby’s fingers and toes.

Sexual organs. Cells form to become the baby’s eggs or sperm. The baby’s private parts (girl/boy) is visible at the end of the embryonic period.

Muscles and movement. Muscles develop and the embryo begins to move. At first it’s only twitching and reacting to touch. Once the nerves and muscles start working together, the baby can start moving on purpose.

A box of jello has a mass of 250 g. How many boxes must be bought to have 1 Kg of jello? *
Igoryamba

Answer:

4

Explanation:

According to the question, one box of jello has a mass of 250grams.

The question wants us to find how many boxes of jello would collectively weigh 1kg.

Since the units of weight here are in grams (g) and kilograms (kg), we need to convert to the same unit

1kilogram (kg) is equal to 100 grams (g).

Hence, if 1 box of jello weighs 250g

1000g of jello box will be 1000/250 in number

1000 ÷ 250 = 4.

Hence, 4 boxes of jello will weigh 1000g or 1kg.

g If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time
Elenna [48]

Answer:

a. 8.1 milligrams

b. 40.07 hours

c. 8.859 milligrams

Explanation:

If a person takes a prescribed dose of 10 milligrams of Valium, the amount of Valium in that person's bloodstream at any time can be modeled by

A_{t}=10e^{-0.0173t}

Where A(t) = amount of Valium remaining in the blood after t hours

t = time or duration after the drug is taken

a. we have to calculate the amount of drug remaining in the bloodstream after 12 hours

A_{12}=10e^{-0.0173\times12}

A_{12}=10e^{-0.2076}

                = 10×0.81253

                = 8.1 milligrams

b. In this part we have to calculate the time when A(t) = 5 milligrams

5=10e^{-0.0173\timest}

\frac{5}{10}=e^{-0.0173t}

0.5 = e^{-0.0173t}

Now we take natural log on both the sides of the equation.

ln(0.5) = ln(e^{-0.0173t})

-0.69314 = -0.0173t

t = \frac{0.69314}{0.0173}

t = 40.0658

 ≈ 40.07 hours

c. In this part we have to calculate the rate, by which amount of drug will decay in the bloodstream after 7 hours.

A_{7}=10e^{-0.0173\times7}

A_{7}=10e^{-0.1211}

              = 10×0.8859

              = 8.859 milligrams
