Drop a paper a piece of thermocol and a piece of plastic from a height of 10 to 15 feet not the time for each object to hit the ground why does paper take more time than thermocol and thermocol more than the plastic piece make the paper to fell down in such a way that it should hit the ground before all of them and how does it happen

Answers

Answer 1

Answer:

The paper takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.

The thermocol takes more time than the piece of plastic because it experiences a greater air resistance.

The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it and then giving it an initial velocity by throwing it downwards.

Explanation:

Objects falling freely due to the force of gravity alone are accelerated downwards at a constant value 9.8 m/s². This acceleration due to gravity is constant for all objects on the earth's surface and is independent of the mass of the objects.Therefore, when objects are release from the same height and allowed to fall freely under gravity, they are accelerated downwards to the same extent and are expected to hit the ground at the same time. However,due to the resistance of the air through which the objects are falling, they may hit the ground at different times depending on the shape of the falling objects.

Objects which have a greater surface area or volume per unit mass will experience a greater air drag or resistance and therefore, will take a longer time than objects of similar mass with a smaller volume or surface area.

The paper has a greater surface area per unit mass than the piece of thermocol, therefore, it takes more time to fall than the piece of thermocol because it experiences a greater air resistance than the thermocol.

The thermocol has a greater surface area per unit mass than the piece of plastic, therefore, it takes more time than the piece of plastic because it experiences a greater air resistance.

The piece of paper can be made to fall faster than all of them and hit the ground faster by crumpling it, thereby reducing its surface area per unit mass it and then giving it an initial velocity by throwing it downwards.

Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock
. Which BEST summarizes this phenomenon?
A. The lithosphere changed the atmosphere. B. The hydrosphere change the atmosphere.
C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere

Answers

Answer:

D. The biosphere change the lithosphere

Explanation:

The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.

D. The biosphere change the lithosphere

This picture shows a cross-section of a blood vessel. The diameter of the

this blood vessel?
lumen
magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m

Answers

Answer:

B. 3.12 x [tex]10^{-3}[/tex] m

Explanation:

From the given picture, it can be deduced that;

the diameter of the image of lumen = 25.0 mm

                                                      = 25.0 ÷ 1000

                                                      = 0.025 m

And,

magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]

But magnification = 8,and diameter of the image of lumen = 0.025 m.

So that;

8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]

⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]

                         = 0.003125

Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

What is the importance of the amniotic egg?

An amniotic egg has a clump of nutrients that is used to sustain the embryo during development. This clump of nutrients is called the yolk, and the yolk sac encloses it.

Answer:

The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.

What is Natural Selection? Give an example for Natural Selection for Survival.

Answers

Answer:

is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds

Explanation:

It's sorta like adapting with extra steps.

Answer: Natural Selection

Explanation: Individuals in a species have variation or mutations.

These differences may either be helpful, such as a giraffe with a long neck, or unhelpful, such as a colour variance in a moth that makes them stand out to predators.

The individuals that are more suited to their environment will survive and breed, passing on their genes.

Those that are not suited will die and their genes will not be in the  ‘gene pool’.

This is the survival of the fittest!

Answers

Complex Carbohydrates

Explanation:

There are different types of macromolecules and they all have different purposes, but for a marathon carbs, specifically, complex ones would be best. This is because carbs are the main source of energy for the body. Additionally, unlike proteins, they allow for long-term energy; so you could run an entire marathon without running out of energy.

Answers

Answer:

BRCA1 and BRCA2 genes

Explanation:

The BRCA1 and BRCA2 genes are tumor suppressor genes that encode breast cancer susceptibility proteins involved in repairing double-strand DNA breaks (DSBs) by the mechanism of homologous recombination. This mechanism uses the sister chromatid of the homologous chromosome as template for repairing DSBs. It has been shown that mutations in BRCA1 and BRCA2 genes alter the molecular mechanism of homologous recombination DNA repair, thereby mutations are not repaired appropriately and persist in the DNA of tumor cells.

Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.

Answers

The cell duplicates it’s contents at the start of mitosis and only divides one time compared to meiosis that divides 2 times thats why chromosome number is lower in meiosis

Relation between mitosis and chromosomes:

During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.

When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.
