Answer:

Similarity of structures due to common ancestry is called homology.

Explanation:

Homology is the relationship that exists between two different organic parts when their genetic determinants have the same evolutionary origin or a common ancestry, that is, it is a feature or characteristic that is shared by all descendants of a common ancestor, and not shared with other groups. For example, the arrangement and structure of limbs in vertebrates are similar, these similarities then come from a common ancestor to all vertebrates.

<h2>Answer is option "b"</h2>

Explanation:

Non-ionizing radiation is radiation that has a lower frequency, or longer wavelength, in the EMR spectrum. These frequencies range from that of power lines, radios, and cell phones, up to visible light. Non-ionizing radiation is not powerful enough to break the chemical bonds in molecules. In general, it is not harmful to human health as radiation per se, but could be harmful in terms of the transfer of heat energy. An example of an emitter of non-ionizing radiation is a microwave oven.
Non-ionizing radiation is less harmful because the rays carry much less energy. Radio waves, light, and even heat are examples of non-ionizing radiation. For the most part, these kinds of radiation do not cause any damage. However, ultraviolet light is a kind of non-ionizing radiation that can be harmful - it can cause mutations in DNA
Non-ionizing radiation is limited to the lower energy range electromagnetic radiation, which is more commonly known as light. However, the light we can see with our eyes, visible light, is only a small section of the electromagnetic radiation spectrum as seen here
Hence the right answer is option "b"

Which of these practices best qualifies as a pseudoscience? developing ways to use star patterns to travel at night

GuDViN [60]

Using the smells of different oils to help a person feel energized is a pseudo science. Thus option C is correct.

<h3>What is pseudoscience ?</h3>

pseudoscience is nothing but a fake science completely different from real science.

It does not work on scientific facts so not genuine as it involves explanations, subjective ideas.

Some examples include Graphology, numerology, and astrology.

It is not accurate, completely empirical observation based, complex, based on different motivations, personal gain.

pseudoscience does not have any scientific standards, scientific hypothesis, experiment, method, result, falsifiability of claims etc.

Thus option C is correct.

What is the difference between an organism's habitat and its niche?

Kruka [31]

Habitat is where it lives, and it's niche is what other organisms it interacts with,what it eats, basically its job in an environment . Think of habitat as the address of the organisms house and the niche kinda like the job it has.

calculate the probability of homozygous dominant offspring result from a cross between two heterozygous parents

Annette [7]

1/4. Make a Punnett square and plug in the two heterozygous genotypes of the parents, put them together and you get the following possible genotypes: AA, Aa, Aa, and aa. One of those is homozygous dominant. 1/4 or 25 percent.

1) Gregor Mendel created the law of independent assortment, that genes are distributed from parent to offspring independently of

Virty [35]

2 = d

3 = a

4 = a

5 = a

I am not so familiar with 1 and 3 sry

Homzygous means two identical alleles so a and c are both homzygous

recessive genes are not expressed if a dominant allele is present but with be expressed if the no dominant allele is present.

If you do a cross test you can determine the percentage.

Hagatha is heterozygous meaning non identical allele like Dd or dD and the other is homzygous recessive meaning that it has identical allele like DD or dd but it's recessive so it's dd.

I hope I helped you helped you enough
