Answer:
A radiograph pen is used to draw lines with different thicknesses
Explanation:
A radiograph pen is a form of a technical pen that is used in drawing most specifically in architectural and engineering drawing.
It comes in different pointing sizes, or in some cases, the stylus can be disassembled to allow changing and replacing it with different styles of different widths to fit in.
For example, a radiograph pen can use a different stylus with a width of 0.35mm, 0.7mm, or 1.4mm, which in turn gives different line thickness when drawing.
Hence, in this case, the correct answer is "A radiograph pen is used to draw lines with different thicknesses."

1.) What is the percentage chance of producing a boy?
2.) What is the percentage chance of producing a girl?
Answer/Explanation:
There is a 50% chance of producing a boy. The is a 50% chance of producing a girl. To find percentage divide the desired factor by the possible outcomes. In this case, it 1 divided by 2 which is 0.5. Multiply the decimal by 100 to find the percentage.
1/2 = 0.5
0.5 x 100 = 50%
12. Plant cells are less likely than animal cells to burst when filled with extra fluid. Which of the
following structures is unique to plants and responsible for this difference.
A cell wall
B. cell membrane
C. mitochondrial
D. chloroplast
Answer:
A cell wall
Explanation:
Plant cells are enclosed by a rigid cell wall. When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting.
What is the term for the parts of the cell that accomplish the basic functions of living things

If a individual posses an allele for a diease but does not have the diease this person is known as a
Answer:
The correct answer is - carrier.
Explanation:
If an individual posses an allele for the disease and does not affect by the disease such a person known as the Carrier of the disease. Such a person only posses one allele of the mutated gene or disease gene and a normal gene in their genotype.
They are mostly heterozygous for the particular trait or disease, therefore, do not get affected by the only allele of the disease gene. Generally, such a disease found in a recessive gene that causes it to masked in a person and carried to the next generation.

What percentage of terrestrial biodiversity can be found in forests? Give three examples of the biodiversity you find in forests.
Answer:
See the answer below

Forest's Biodiversity generally refers to the variety of living organisms present in the forest, including plants, animals, and microorganisms. Hence, the forest has plant biodiversity, animal biodiversity, and microbial biodiversity.
The diagram shows the colonization of an island habitat that has never been occupied by a particular species of beetle. Which statement regarding the diagram is true?
the beetles on the island have higher rates of mutation due to their isolation and mutants always have a natural selective advantage
the beetles on the island have a greater amount of genetic variety than the original population of that species of beetle (stabilizing selection)
the one beetle that was introduced to the island is the common ancestor of all of the beetles of that species on the island showing founder effect (genetic drift)
the beetle species on the island shows a case of disruptive selection and increasing genetic diversity

Which statement best describes energy transfer in a food web
(1) energy is transferred to consumers, which convert it to nitrogen and use it to make amino acids.
(2) Energy is transferred to converted into oxygen and transferred to consumers
(3) Energy from the sun is stored in green plants and transferred to consumers.
(4) Energy transferred to consumers, which use it to produce food.
Answer:
4)
Explanation:
when dealing with the food chain and how the energy transfer out through the food chain. you have to first think about the supporters of the food chain which are the consumers see the consumers consume as much as they can to be able to reduce the food when they able to reduce the food it balances out between the other supporters in the food chain for example the consumers, producers, decomposers
the chart shows weather data for a city
In a food chain, if 50,000 calories of energy are in the Ferns. How many calories of
energy will be available for the fish, which are the secondary consumers?
Answer:
500 calories
Explanation:
If ferns are primary producers and they only get 50000 calories then the next level of the food pyrimid will only get 1o percent of that. Next come primary producers which would get 10 percent of what the primary consumers would get so they would get 5000 calories. Next would be the secondary consumers which is the fish. they would get 10 percent of what the primary producers get so they would only be receiving 500 calories. I HOPE THIS HELPS
