Answer:

1. Golgi apparatus- 2. produces lysosomes

2. Lysosome- 3. digests foreign material

3. Smooth endoplasmic reticulum- 1. produces lipids and fats

4. nucleus- 4. command other organelles

1. Golgi apparatus- 2. produces lysosomes

The proteins are synthesized in a rough endoplasmic reticulum. These proteins are packed in a vesicle and send to the golgi apparatus. The proteins and others cellular components not required by the cell are packed by golgi apparatus in a vesicle or number of vesicles also consisting of digestive enzymes. These vesicles are called as lysosomes. 2. Lysosome- 3. digests foreign material

Lysosomes are the organelles found in animal cell, they contain digestive enzymes like acid hydrolases. The enzymes facilitates the digestion of organelles, foreign agents like viruses and bacteria, food particles and other cellular wastes.

3. Smooth endoplasmic reticulum- 1. produces lipids and fats

Smooth endoplasmic reticulum is a meshwork of tubes it is attached with the periphery of the cell. The main function of the endoplasmic reticulum is the synthesis and storage of lipids like phospholipids, cholesterol and fats.

4. nucleus- 4. command other organelles

The nucleus is the command center of the cell. It contains the hereditary information of the cell in the form of genetic material. The genetic material is the form of genes, which when express result in the synthesis of proteins by the cell organelles like ribosomes, rough endoplasmic reticulum.

One of the earliest atomic models was suggested by John Dalton in the early 1800s.

Nonamiya [84]

Answer:

D. Atoms are like solid balls

Explanation:

John Dalton proposed that all matter is composed of very small things which he called atoms. This was not a completely new concept as the ancient Greeks (notably Democritus) had proposed that all matter is composed of small, indivisible (cannot be divided) objects. When Dalton proposed his model electrons and the nucleus were unknown.

In the laboratory a student uses a "coffee cup" calorimeter to determine the specific heat of a metal. She heats 19.6 grams of z

storchak [24]

Answer:

The specific heat of zinc is 0.375 J/g°C

Explanation:

Step 1: Data given

Mass of zinc = 19.6 grams

Mass of water = 82.9 grams

Initial temperature of zinc T1= 98.37 °C

Initial temperature of water T1= 24.16 °C

Final temperature of water (and zinc) T2 = 25.70 °C

Specific heat of water = 4.184 J/g°C

Step 2: Calculate Specific heat of zinc

Q=m*c*ΔT

Qzinc = -Qwater

m(zinc)*C(zinc)*ΔT(zinc) = -m(water)*C(water)*ΔT(water)

⇒ with mass of water = 82.9 grams

⇒ with C(water) = 4.184 J/g°C

⇒ with ΔT(water) = T2 - T1 = 25.70 - 24.16 = 1.54

⇒ with mass of zinc = 19.6 grams

⇒ with C(zinc) = TO BE DETERMINED

⇒ with ΔT(zinc) = T2 -T1 = 25.70 - 98.37 = -72.67°C

Qzinc = -Qwater

m(zinc)*c(zinc)* ΔT(zinc) = - m(water)*c(water)* ΔT(water)

19.6g* C(zinc) * (-72.67°C) = - 82.9g* 4.184 J/g°C * 1.54 °C

-1424.332*C(zinc) = -534.155

C(zinc) = 0.375 J/g°C

The specific heat of zinc is 0.375 J/g°C

When two hydrogen atoms bond with one oxygen Atom to form water what happens to the electrons

Likurg_2 [28]

Most bonds are made when a positive atom or molecule (one that is missing an electron in its outer shell) accepts an electron from a negative atom or molecule. Hydrogen is a positive ion because it only has one electron in its outer shell instead of a pair. Oxygen has paired electrons, but because it is highly electronegative one of the outer electrons is held closer to the nucleus, creating a partial negative charge. This partial negative charge attracts the electron in the outer shell of hydrogen and creates a bond. This type of bond accounts for the high surface tension in water.
