Answer:

golgi body

Explanation:

i took the test

Organelle packages materials and distributes them throughout the cell through the Golgi body (also known as the Golgi apparatus or Golgi complex). The correct option is C.

The Golgi body plays a crucial role in the packaging, modifying, and sorting of proteins and lipids synthesized in the endoplasmic reticulum (ER). It receives these molecules from the ER and then modifies them, such as by adding sugars or lipids. The Golgi apparatus then packages these molecules into vesicles and distributes them to their appropriate destinations within the cell, such as other organelles or the cell membrane.

A. Lysosome: Lysosomes are organelles responsible for the digestion of waste materials, cellular debris, and foreign substances. They contain enzymes that break down various molecules. Lysosomes are not involved in packaging and distributing materials throughout the cell.

B. Chloroplast: Chloroplasts are organelles found in plant cells responsible for photosynthesis, the process by which sunlight is converted into chemical energy. Chloroplasts are involved in producing energy-rich molecules (such as glucose) rather than packaging and distributing materials within the cell.

D. Cell membrane: The cell membrane (also known as the plasma membrane) is a semipermeable barrier that surrounds the cell, separating its internal environment from the external environment. While the cell membrane controls the entry and exit of substances into and out of the cell, it is not directly involved in packaging and distributing materials within the cell.

Therefore, the Golgi body is the correct answer as it specifically carries out the task of packaging and distributing materials throughout the cell.

Explanation:

Given :

Walk in forward direction is 30 m .

Walk in backward direction is 25 m .

To Find :

The distance and displacement .

Solution :

We know , distance is total distance covered and displacement is distance between final and initial position .

So , distance travelled is :

D = 30 + 25 m = 55 m .

Now , we first move 30 m in forward direction and then 25 m in backward direction .

So , displacement is :

D = 30 - 25 m = 5 m .

Therefore , distance and displacement covered is 55 m and 5 m respectively .

Hence , this is the required solution .

Answer:

A.) 42.7 m/s

B.) 0.33 m/s^2

C.) 90 kg

Explanation:

A.) If Justin races his Chevy S-10 down highway 37 north for 2,560 meters in 60 seconds, what is his velocity? 

Velocity = displacement/time

Velocity = 2560/60

Velocity = 42.67 m/s

B.) The Chevy S-10 started rounding at 10 meters per hour. What is the acceleration at 30 seconds on the highway?

Acceleration = velocity/time

Acceleration = 10/30

Acceleration = 0.33 m/s^2

C.) The S-10 has a force of 30 N. What is the mass of the car?

Force = mass × acceleration

30 = mass × 0.33

Mass = 30/ 0.33

Mass = 90 kg

Explanation:

Liquid and gases  state(s) of matter have no definite shape or volume

Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gases, and plasma.

These different states of matter have different characteristics according to which they vary their volume and shape.

The solid has a definite shape and definite volume because the atoms and molecules of the solid are very close to each other forming a great bond structure.

The liquid and gaseous state have their atoms and molecules apart from each other forming a loose bonding structure because this liquid does not have a fixed shape it takes the shape of the container, similarly, gases, their atoms are far apart from each other that's why they don't have fixed shape or the fixed volume.

States of matter those have no definite shape or volume are liquids and gases.

Answer:

a)The vehicle will enter your lane

Explanation:

The complete question is

You are driving down a two-lane road at 45 mph. The oncoming vehicle's right  wheels drop off the pavement. The most likely occurrence is...

a)The vehicle will enter your lane

b)The vehicle will continue on the shoulder of the road.

c)The vehicle will spin out and hit a tree.

d)The vehicle will return smoothly back onto the road.

The dropping off of the oncoming vehicle's right wheel off the pavement will force the driver to overturn to the left towards you, and this might lead to the vehicle entering your own lane.

Solubility: the ability of a substance to dissolve in another.

Density: the amount of mass in a given volume.

Buoyant force: the upward force on an object in a fluid.

Conductivity: the ability of a substance to transfer heat or electricity.

Boiling point: the temperature at which a liquid becomes a gas.

Solubility can be defined as a measure of how readily a substance dissolves in a solvent to form a solution.

Density can be defined as mass all over the volume of an object.

Buoyancy can be defined as an upward force created by the fluid (liquid) displaced by an object.

Conductivity can be defined as the ability of an object, substance or body to transfer heat or electricity to another.

Boiling point is the temperature at which a physical matter changes phase from liquid to gas.

Answer:

3 m/s

Explanation:

First, find the time it takes to land.

Given in the y direction:

Δy = 0.8 m

v₀ = 0 m/s

a = 10 m/s²

Find: t

Δy = v₀ t + ½ at²

0.8 m = (0 m/s) t + ½ (10 m/s²) t²

t = 0.4 s

Next, find the velocity needed to travel 1.2 m in that time.

Given in the x direction:

Δx = 1.2 m

a = 0 m/s²

t = 0.4 s

Find: v₀

Δx = v₀ t + ½ at²

1.2 m = v₀ (0.4 s) + ½ (0 m/s²) (0.4 s)²

v₀ = 3 m/s

Answer:

The pressure in pipe b is 33.4 kpa.

Explanation:

Given that,

Pressure in pipe a = 30 mm hg vacuum

Differential reading = 0.30 m

We need to calculate the pressure in pipe b

Using diagram

[tex]P_{B}+W_{oil}(h_{1}+h_{2})-W_{Hg}(h_{2})-W_{H_{O}}(h_{1})=P_{A}[/tex]

Where, P = pressure

W= specific weight

Put the value into the formula

[tex]P_{B}+W_{oil}(0.15+0.30)-W_{Hg}(0.3)-W_{H_{2}O}(0.15)=-W_{Hg}(0.030)[/tex]

Put the value of specific weight

[tex]P_{B}=-(133)\times(0.030)-(8.95)\times(0.45)+133\times(0.3)+9.80\times0.15[/tex]

[tex]P_{B}=33.4\ kPa[/tex]

Hence, The pressure in pipe b is 33.4 kpa.

Answer:

Explanation:

18 km / h

= 300 m / min

12 km / h = 200 m / min

distance travelled in 200 minutes = 300 x 200 = 60000 m

distance travelled in 50 minute in return journey = 200 x 50 = 10000 m

total distance travelled = 70000 m

total time = 250 minute

speed = 70000 / 250

= 280 m / min

= 16.8 km / h

Total displacement = 60000 - 10000 = 50000 m

total time = 250 min

velocity = 50000 / 250

= 200 m / min

= 12 km / h

Answer:

11.3 km/sec * 1000 m/km / 1609 m/mi = 7.02 mi / sec

7.02 mi/sec * 3600 sec / hr = 25,300 mph

The value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.

Given the following data;

In this exercise, you're required to convert the value of the speed needed to escape the pull of Earth's gravity in kilometer per seconds (km/s) to miles per hour (mi/h).

Conversion:

1 mile = 1.609 kilometer

X mile = 11.3 kilometer

Cross-multiplying, we have;

[tex]1.609[/tex] × X = [tex]11.3[/tex]

[tex]X = \frac{11.3}{1.609}[/tex]

X = 7.0230 miles

Since we know that one (1) hour is equal to 3600 seconds, we would multiply the value of X by 3600 in order to convert it to miles per hour (mi/h).

X = 7.0230 × 3600

X = 25282.8 mi/h

Therefore, the value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.
