Which of the following is NOT a way in which line is created?

O Dot-to-dot placements
O Use of linear objects
O Sequential placement of materials
O Use clusters of filler materials

Answers

Answer:

Use clusters of filler materials

Explanation:

A line can be defined as a one-dimensional figure that is straight, has no thickness (width) but extends infinitely in both directions.

Generally, a line can be created through the use of the following techniques or methods;

1. Dot-to-dot placements i.e distance between two points.

2. Use of linear objects: it involves the use of an object that is straight in shape.

3. Sequential placement of materials.

However, a line cannot be created through the use of clusters of filler materials.

Look at the diagram below. It shows two solutions separated by a partially permeable membrane. Which number arrow shows the direction in which water molecules will move?

Answers

Answer:

Arrow no. 4

Explanation:

Water flows from a region of higher concentration to a region of lower concentration, i.e, osmosis.

Dilute solution means it has relatively less solute and more solvent, meaning more amount of water.

And just the opposite for concentrated solution.

So since the dilute solution has more water and concentrated solution has less, and water moves from a region of higher concentration to a region of lower concentration, option 4 is the correct answer.

During the osmosis process solvent is moved from a lower solute concentration to a higher solute concentration, hence arrow 4 defines the movement of water molecules.

What is osmosis?

Osmosis is the process through which solvents move from a region of lower solute concentration to one of higher solute concentration across a semi-permeable membrane.

Water in the cell acts as a solvent and moves from lower solute concentration to higher solute concentration through a partially permeable membrane.

Conversely, in diffusion, molecules migrate from an area of greater concentration to regions of lower concentration without the need for a semi-permeable barrier.

Therefore diffusion of water molecules in the osmosis process from low solute concentration to high solute concentration, hence arrow 4 defines the movement of water molecules.

Stages of Human Gestation First trimester Second trimester Third trimester - Embryo develops - Organs begin to develop - (1) - Starts swallowing - Fat begins to develop - (2) - All organs are developed - Can hear and see - (3)

Answers

Answer:

Im doing the unit test and i believe the answer is C

Fertilization may be defined as a biological event that occurs by the fusion of male and female gametes successfully to produce a zygote.

The embryo develops after four to five weeks of conception which is the first trimester, organs initiate to develop by the end of the first trimester.

Swallowing is initiated at the beginning of the second trimester, and all organs are completely developed by the initiation of the third trimester. While all senses of hearing and seeing are developed by the middle of the third trimester.

Therefore, each trimester is characterized with its own functionality.

HELP PLEASE! Choose 3 of the water quality indicators write a summary of what it is

Answers

Answer:

Explanation:

Dissolved oxygen (DO)

The DO test measures the amount of oxygen dissolved in the water. Oxygen is essential for both plants and animals, but high levels in water can be harmful to fish and other aquatic organisms.  

Water temperature

Aquatic organisms are dependent on certain temperature ranges for optimal health. Temperature affects many other parameters in water, including dissolved oxygen, types of plants and animals present and the susceptibility of organisms to parasites, pollution and disease.

pH

A pH test measures the alkalinity or acidity of water. A pH of 7 is neutral, below 7 is acidic and above 7 is basic or alkaline. Acid rain, from auto exhaust or other pollutants, causes a drop in the pH. Pollution from accidental spills, agricultural runoff and sewer overflows can also change the pH.

Escherichia coli (E. coli)

E. coli is a fecal coliform bacteria that comes from human and animal waste. The Environmental Protection Agency uses E. coli measurements to determine whether fresh water is safe for recreation. Disease-causing bacteria, viruses and protozoans may be present in water that has elevated levels of E. coli. Levels of E. coli can increase during flooding. E. coli is measured in number of colony forming units. The EPA water quality standard for E. coli bacteria is 394 colony forming units per 100 mL.

D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.

Sequence differences in genes or genomes are used to determine organisms that are most related to each other based on evolution.

What does sequence difference mean?

Sequence differences are differences which exists in the entire genome or a gene which code for proteis s whivh are related on function or structure in two organisms.

For proteins performing similar functions, organisms which have the least sequence differences are usually the most related organisms in an evolutionary sense whereas, organisms with the most sequence differences are the least related.

Therefore, sequence differences in genes are used to determine organisms that are most related to each other based on evolution.
