why are the models of solar systems that you can purchase in stores not to scale?

Answers

Answer:

It's impossible to find a solar system model that is to scale because of how large the solar system is. The solar system is about 287 billion km, making it impossible to purchase or even create a solar system model that is to scale.

The models of the solar systems purchased in stores are not to scale because they are too large to be replicated to scale.

The solar system is a series of planetary bodies which consists of the sun and planetary bodies which orbits around the sun. The solar system is immensely huge with an approximate diameter of about 287.46 billion kilometers.

The entire earth itself has an approximate Circumference of about 40,075 km which is extremely small in comparison to the solar system's diameter.

This means that to produce a model of the solar system to scale, the diameter of the replicated model will be 287.46 billion kilometer which is impossible as it is too large to be replicated to scale even immensely larger Than the diameter of the earth.

i need 2 paragraphs about which is better between organic food or gmo

Answers

Answer:

Most commonly found in crops such as soybeans, corn and canola, GMOs are designed to provide a higher nutritional value to food, as well as protect crops against pests. Organic foods, on the other hand, do not contain any pesticides, fertilizers, solvents or additives.

Organic is non-GMO because the use of GMOs is prohibited in organic production. For example, organic farmers cannot plant GMO seeds, organic livestock cannot eat GMO feed, and organic food manufacturers cannot use GMO ingredients.

From a health perspective, GMO food is no different than non-GMO food. In fact, they can even be healthier. Imagine peanuts that can be genetically engineered to reduce levels of aflatoxin, and gluten-free wheat, which would give those with celiac disease a healthy and tasty bread option

GMO foods are as healthful and safe to eat as their non-GMO counterparts. Some GMO plants have actually been modified to improve their

Read the section "Seeds." Which sentence from the section states the main idea about seeds? A The life cycle of flowering plants begins with a seed. B The outside of a seed is called a shell. C The wind blows some, and others float on water. D The next phase starts when a seed gets someplace it can start growing.​

Answers

Answer:

A The life cycle of flowering plants begins with a seed.

Explanation:

Seeds are structures found only in a group of plants called higher plants, comprising of gymnosperms and angiosperms. Seeds are the developed/fertilized ovules of a plant.

Seeds are basically the reproductive unit of the angiosperms, also called FLOWERING PLANTS i.e. plants that produce flowers (reproductive structures). This means that the life cycle of flowering plants begins with the germination of the EMBRYO in a SEED.

Answers

Answer:

To determine the effect of toxin binding, you perform a Competitive Binding Experiment

Explanation:

Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.

They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.

They are important because:

1. Validate a direct binding assay

2. Confirm whether or not a drug binds to the receptor

3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

Prokaryote: lack of membrane-bound nucleus, DNA in cytoplasm, single circular chromosome

Eukaryote: Membrabe-bound nucleus, DNA inside nucleus, multiple chromosome.

Explanation:

Prokaryotes are one of the two domains, which consists of organisms that do not possess a membrane-bound nucleus. Due to this fact, the genetic material (DNA) of prokaryotic organisms like bacteria is found located in their cytoplasm. The DNA is found as a single circular chromosome in a region called NUCLEOID.

On the contrary, eukaryotes are the second domains of organism characterized by their possession of a membrane-bound nucleus that houses their genetic material (DNA). All the DNA of an eukaryotic organism like plants, animals etc. are found inside its NUCLEUS. They are made up of multiple linear chromosomes.

B. Food chains focus on energy transfers, but food webs do not.

C. Food chains focus on the internal energy cycles of animals, unlike food webs.

D. Food webs do not show connections between animals like food chains.

Answers

Question: "What is the main difference between food chains and food webs?"

Answer: "The best way to analyze this question would be to compare the two diagrams; when looking at a food chain, it is much easier to understand as to easily seeing the organism on the bottom (start) and the top (end) of the food chain, depending on its ecosystem. However, a food web on the other hand branches off into more complex details of every living thing connected to each other and how their roles effect the 'web'. So, this being said, I would say out of the options given above, Option A is the best choice."

B.They each have their own nucleus.
C.They will most likely undergo mitosis.
D.all of the above

Answers

I believe it’s b hope this helps:$

Cell division creates daughter cells. After DNA replication, mitosis produces two daughter cells. Therefore, option (D) is correct.

What are daughter cells?

The cell that undergoes the process of cell division and results in the production of two daughter cells is referred to as the mother cell or the parent cell. The genetic make-up of the mother cell is maintained in both of the daughter cells that are formed when mitosis is carried out.

These freshly generated daughter cells have the potential to further divide and expand, so giving rise to a new cell population. This new cell population is formed by the division and expansion of a single parental cell and its daughter cell.

Therefore, all the above options are correct about daughter cells.

The genetic code of a strand of DNA is determined by a specific sequence of three nucleotides.

What are nucleotides?

The sequence of nucleotides in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that determines the amino acid sequence of proteins is known as the genetic code.

The genetic code for each amino acid is a three-nucleotide sequence. A codon is a three-nucleotide sequence in messenger RNA that specifies a certain amino acid.

The sequences of DNA are made up of nucleotide bases. These bases are thymine, adenine, cytosine, and guanine. The letters A, C, G, and T in DNA determine our unique genetic code and offer instructions for the body to produce molecules.

Therefore, a precise sequence of three nucleotides determines the genetic code of a strand of DNA.

Could emigration or immigration have played a major role in determining the size of the reindeer
population? Explain. Think about where these reindeer were and whether they could swim that far

Answers

Answer:

Yes.

Explanation:

Yes, emigration or immigration have played a major role in determining the size of the reindeer  population in specific area because immigration is done by the animals in search of food. The animals moves from one region to another in search of food so due to this movement the population of reindeer decreases in that specific area. Reindeer are good swimmers so due to this ability they cross the vast Yukon River which is half mile wide.

Explanation:

Smooth coat (S) is dominant over rough coat (s) and black coat (B) is dominant over white coat (b).

SsBb   x   SsBb

Offspring (You can also see the attached image for the Punnet's square analysis)

9 S_B_ = Smooth black coat

3 S_bb = smooth white coat

3 ssB_ = rough black coat

1 ssbb = rough white coat
