Answer:

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.

Answer: Function. Vitamin A helps form and maintain healthy teeth, skeletal and soft tissue, mucus membranes, and skin. It is also known as retinol because it produces the pigments in the retina of the eye. Vitamin A promotes good eyesight, especially in low light. Vitamin A (retinol) is ingested as either retinyl esters or carotenoids and metabolized to active compounds such as 11-cis-retinal, which is important for vision, and all-trans-retinoic acid, which is the primary mediator of biological actions of vitamin A

Basically, when people say that DNA replication is semi-conservative they are saying that two identical copies are being made from the original DNA strand.

Explanation:

The two new strands contain one side of the original DNA and another side of  synthesized pair.

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.

Answer: By Snell's law, we can see that the angle of refraction is 30.34°

Explanation:

Snell's law says that:

If a ray in a medium of refractive index n₁, insides with an angle θ₁ in another medium with refractive index n₂, then the angle of refraction θ₂ is given by:

n₁*sin(θ₁) = n₂*sin(θ₂)

We know that:

The incidence angle is 45°, then: θ₁ = 45°

We can assume that the first medium is air, then n₁ = 1

The refractive index of the other medium is 1.4, then n₂ = 1.4

Replacing these in the Snell's law equation we get:

1*sin(45°) = 1.4*sin(θ₂)

Now we can solve this for the angle of refraction:

sin(45°)/1.4 = sin(θ₂)

Asin(sin(45°)/1.4 ) = Asin( sin(θ₂)) =  θ₂ = 30.34°

So the angle of refraction is 30.34°

Answer: C

Explanation: it gets weaker because there not as close together

Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.

Answer:

Density dependant limiting factor

Explanation:

Answer:

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.

Hope it helps!!!

ionic bonds and covalent bonds.

Explanation:

hope this helps :)

A spore grows into a mature gamete producing plant is best describe the life cycle of fern.

The life cycle of the fern has two different stages such as sporophyte and gametophyte. The sporophyte stage which releases spores whereas gametophyte stage which releases gametes. Gametophyte plants are haploid whereas sporophyte plants diploid. This type of life cycle is known as alternation of generations.

So we can conclude that a spore grows into a mature gamete producing plant is best describe the life cycle of fern.

Answer:

1 in 4 so 25% ---------------

Answer:

20, Im not completely sure tho

Explanation:

Answer:

Cause: Earth’s magnetosphere traps radioactive  solar wind particles in bands around Earth → Space travel through the Van Allen  belts is dangerous.

Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.

Cause: Solar wind particles interact with Earth’s  upper atmosphere → Effect: An aurora is created

Explanation:

I have been able to drag the tiles to the correct boxes to complete the pairs.

When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone  where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind.  The solar wind  are captured by and held around a planet by that planet's magnetic field.

When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.

Answer:

Cause: Earth’s magnetosphere traps radioactive

solar wind particles in bands around Earth.

Effect: Space travel through the Van Allen

belts is dangerous.

Cause: Earth is surrounded by a magnetic field.

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%

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.

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%

Therefore, the percentage of the sample is made up of adenine, A is 28%
