A central heating system provides warmth to the whole interior of a building from one point to ... Institutional heating systems (office buildings or schools, for example) can use low-grade, inexpensive
An alternative to district heating would be to build a small district heating plant together with your neighbours, which is known as local heating or joint heating. ... The local heating system also includes a network of pipes and a common boiler plant that delivers heat through the pipework to the single-family houses.

If 22% of a DNA sample is made up of cytosine, C, what percentage of the sample is made up of adenine,
A?
Answer:
28% of Adenine
Explanation:
Chargaff's Rule states that A = T and C = G
Because of that, the sample must have the equation:
A + C = T + G
G must have the same amount as C so,
A + .22 = T + .22
Both sides of the equation must equal each other by .50, so .50 - .22 = .28
.28 x 100 = 28%
If 22% of a DNA sample is made up of cytosine, C, the percentage of the sample is made up of adenine, A is 28%
What is DNA?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are the same.

A species of beetle can be either black or brown in color. The beetle's color is determined by a single gene, and black is recessive to brown. The soil in the area has become darker and closer in color to the black beetles. Which of the following will most likely occur?
Selective pressures will decrease the number of brown beetles.
Selective pressures will increase the number of brown beetles.
Selective pressures will decrease the number of black beetles.
The overall size of the beetle population will continue to decrease over time.
Answer:
the first option
Explanation:
As the soil gets darker, brown beetles become easily recognised by predators (like birds) and will be eaten. Black beetles however, are better camouflaged and will less likely be spotted by the birds. Black beetles will survive and interbreed, allowing the recessive allele to be passed on to upcoming generations.
Selective pressure is what makes the genetic pool shift toward a particular genotype with a particular phenotype (recessive black in this case) that gives the new generations a selective advantage. They're more likely to survive and reproduce. Survival of the fittest.
Genotype- the genetic makeup of an organism (eg: the recessive gene for black; bb)
Phenotype- physical feature of an organism as determined by the genotype (the colour black)
Selective pressures will increase the number of brown beetles. The correct option is 2.
What is Selective pressure?Any factor that reduces or increases reproductive success in a subset of a population may exert evolutionary pressure, selective pressure, or selection pressure, thereby driving natural selection.
Selection pressure can be defined as a force that causes an organism to evolve in a specific direction.
It is not a physical force, but rather an interaction between natural variation in a species and environmental factors that causes certain forms to have an advantage over others.
A beetle species can be either black or brown in color. A single gene determines the color of the beetle, and black is recessive to brown.
The soil in the area has darkened and taken on the color of black beetles. Brown beetle populations will increase as a result of selective pressures.
Thus, the correct option is 2.

Answer: The question is incomplete because the options were not given but the options has been gotten from another website.
Here are the options.
a. Wood is routinely recycled to make new wood-based products.
b. Wood products can be manufactured from different tree species.
Eliminate
c. Wood may be replenished by planting new trees to replace those being used.
d. Wood products can be manufactured using various other materials such as plastics.
The correct option is c.
Wood may be replenished by planting new trees to replace those being used.
Explanation:
This is because wood is a Renewable resource because Renewable resources are resources that can be replenish or reproduce again after usage either by naturally producing another one. Theses resources are not exhausted because they can naturally be reproduce again. Wood is a Renewable resources because new ones are planted to replaced the used ones.

Which inferences about sodium (Na) are true?
Answer:
true c this is the answer
Why does sodium and potassium ions need a protein pump to pass through the cell membrane?
A. The ions have a charge and cannot pass directly through the cell membrane.
B. The ions are moving against the concentration gradient.
C. Energy is needed to move the ions.
D. All of the above.
Cell membrane have been the selective membrane that allows transportation. Sodium and potassium ions need a protein pump as they are charged particles that move against the gradient and need energy. Thus, option D is correct.
What is active transport?Active transport has been the way to move ions and molecules inside and outside the cell membrane. This system of transportation requires energy as the ions move from low concentration regions to the region of the higher electrochemical area.
The sodium and potassium pump needs proteins and energy to move the ions as the inside of the cell is rich in potassium and the exterior is rich in sodium ions. The charged ions moving against the concentration cannot enter the cell without energy and protein pumps.
Therefore, option D. all of the above statements are correct.

Explain the unique information trace fossils and coprolites can help scientists infer about an organism
They're trace fossils, not animal bodies. This coprolite can reveal an animal's diet. Scientists can determine what animal dropped coprolites based on its shape, size, and location.
What are coprolites?Fossilized feces are known as coprolites. Because coprolites provide information for the animal's behavior rather than its shape, rather than being considered body fossils, they are instead categorized as trace fossils.
A coprolite can provide researchers with information about an animal's nutrition. Scientists are able to determine the species of animal that may have been responsible for the droppings by analyzing the shape and size of the coprolites as well as the location where they were discovered.
Because coprolites have a propensity to deteriorate so quickly, we only find them very infrequently. They are the marine species that are found the most frequently. The presence of coprolites in fish and reptiles is very common.
