Answer:
scientific explanations are descriptions that are tested, observed, and backed up with evidence for realities in the natural world.
what is it light and how does it travel?
Answer:
Light is both waves and particles, which are described as packets of energy called photons. These waves, or photons, travel in narrow beams called rays. Only when light rays move from one medium to another, such as from air to water, their linear paths altered.

3. In science, a theory is more like a scientific law than a hypothesis. A theory
explains a set of observations or events. It must be verified multiple times by
many different scientists. One scientist cannot create a theory on his or her own.
a) Look back at your hypothesis from question 2. Could this hypothesis become
a theory if you repeated your experiment 100 different times and got the same
results? Can a theory be created by just one person? (2 points)
Answer:
No
Explanation:
A theory cannot be made by one person, no matter how many times they repeat the experiment. Therefore, you repeating the experinment does not make it a theory. The experinment must be repeated by others and get same result as you to confirm it as theory.
In most cases, bioluminescence is useful for:
attracting prey
producing oxygen
supporting plant life
navigating dark waters

Answer:
Attracting prey
Explanation:
Rule out other answers.
Plants in dark water already are adapted.
If a fish such as an angler fish lives in dark waters then there would not be a need to create light to see because then they could just live in a different part of the ocean.
Light doesn't create oxygen.

In this question we will transcribe DNA to RNA
What is DNA and RNA?It consists of a pentose, a phosphate and has
adenineguaninecytosine and uracil as nitrogenous bases.RNA, unlike DNA, is composed of only one strand and it is produced in the cell nucleus from one of the strands of a DNA molecule. Once ready, the RNA goes to the cell cytoplasm, where it will perform its main function, which is to control protein synthesis.

A genetic change that occurs in a body cell of a mouse will not contribute to the continued genetic diversity of the species because.
Answer:
The genetic material in the germline cells is passed onto offspring, not somatic cells.
Explanation:
A body cell is another terms for somatic cell. Germline cells refer to cells involved in reproduction, like the egg and sperm. During reproduction, only these cells combine to start creating the new life. Therefore, the genetic changes that occur in body cells have no effect on the offspring because the change is not also found in the germline cells. Should there be genetic changes in the germline cells, then these alterations would be present in the offspring.
Which compound can only be made if it has access to magnesium ions?
Answer:
Hope it helps
Explanation:
Green plants absorb light in their leaves and convert it to energy by photosynthesis. Temperature, carbon dioxide concentration and light intensity can affect the rate of photosynthesis.Plants need minerals for healthy growth. They are absorbed through the roots by active transport as mineral ions dissolved in the soil water.Magnesium ions and nitrate ions are needed by plants. A plant will not grow well if it cannot get enough of these ions, and it will show symptoms of mineral deficiency. Fertilisers are used to replace minerals used by plants.
Nitrogen fertilisers - such as ammonium nitrate and ammonium phosphate - provide plants with water-soluble sources of nitrogen that they can absorb through their roots. They allow farmers to increase the yield and quality of their crops. However, overuse can cause problems. Eutrophication happens when excess nitrate (or phosphate) enters rivers or lakes from fields. This can lead to the death of fish and other aquatic animals.
James Surowiecki's analysis is consistent with the slogan that: A. too many cooks spoil the broth. B. birds of a feather flock together. C. two heads are better than one. D. opposites attract.
James Surowiecki's analysis is consistent with the slogan that two heads are better than one and it is a proverb and there are several acronyms too. Thus, option C is correct.
What is acronym?Acronym has been defined as the short form of long words such as very important person and the acronym of very important person has VIP. The word acronym has been used to denoted the short term of a word in which two or more than two words combined together to form new short word.

3. A cell with 10 chromosomes undergoes mitosis.
(a) How many daughter cells are created:
Answer:
In a cell with 10 chromosomes undergoes mitosis, the result are 2 daughter cells each with 10 chromosomes
Explanation:
Cells have the ability to reproduce or replicate through 2 processes:
Mitosis
Meiosis
Mitosis differs from meiosis because the final result is always
2 daughter cells
The daughter cells are identical to the mother cell and this includes the same number of chromosomes
This means in mitosis 1 cell with 10 chromosomes leads to two identical cells each with 10 chromosomes.
