How does the stratigraphic principle help us determine the age of layers of rocks?

Answers

Answer 1

Answer:

The principles of stratigraphy help us understand the relative age of rock layers. Layers of rock are deposited horizontally at the bottom of a lake (principle of original horizontal). Younger layers are deposited on top of older layers (principle of superposition). Layers that cut across other layers are younger than the layers they cut through (principle of cross-cutting relationships). The principle of superposition builds on the principle of original horizontal. The principle of superposition states that in an unreformed sequence of sedimentary rocks, each layer of rock is older than the one above it and younger than the one below it. Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.

A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.

Answers

Answer:

A

Explanation:

A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.

The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.

The correct option is A.

A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.

CELL:

Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism.

Cells contain organelles that help them perform specific functions. Organs are made up of numerous cells.

Similar cells perform similar functions while dissimilar cells perform dissimilar functions.

Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.

A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.

Answers

The box would stay at rest where it lies since the same amount of force is pulling it in opposite directions :)

Since 10 N forces are acting from both sides, these are balanced forces and the box will not move because balanced forces are acting on it. So the correct option is D.

What are balanced forces?

Forces that are equal in magnitude and opposing in direction are said to be balanced forces. Equilibrium is seen as a condition of balanced forces. There is no shift in direction when the forces are in balance.

Balanced combined forces have always been equal to zero. These are vectors for merging. Balance forces cannot alter an object's momentum or direction.

An item is kept traveling at a constant speed by a balanced force. In it, Newton's First Law of Motion is explained. A good illustration of a balanced force is a book on the table. The normal force (support force) of the table balances out the weight of the book. The two forces are exactly equal and opposed to one another.

While forces that are balanced can keep an item at rest or move at a steady speed, unequal forces can cause things to accelerate.

Therefore the correct option is D.

A: Amino acid sequence
B: Dietary preferences
C: Habitat requirements
D: Social group interactions​

Answers

Answer:

A

Explanation:

Studying amino acid sequences would provide the best evidence that two organisms share a common ancestor.

Amino acid sequence is a series of bases with different letters usually four(A T C G or U)  this letter contains information of an individual when translated.

The amino acid sequence of 2 or more individuals can be compare to each other through the process called Blasting using a tool called Blast

Blast generates alignments or similarities between a amino acid or protein sequence.

For organisms that are phylogenetically close i.e related by an ancestor, there will be similarities between their DNA sequences when compared. The amino acid sequence of an individual contains the information of the individual and it is unique for each individual.

Hence, amino acids sequence provides the best evidence of organisms sharing a common ancestor.
