Which best explains why it is difficult to classify protists?
Protists are difficult to characterize because of the great diversity of the kingdom. These organisms vary in body form, nutrition, and reproduction. They may be unicellular, colonial, or multicellular.
Why is it difficult to explain one certain way a protist reproduces?It is hard to demonstrate one certain way a protist reproduces :
Some protists use agamic reproduction at one stage in their life and then use gamic reproduction at another stage in their life.
Thus, Protists are difficult to characterize because of the great diversity of the kingdom.

How does a comparison of bone structures of two animal provide evidence of an evolutionary relationship
Answer: Comparative Anatomy
Both provide evidence for evolution. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.
Explanation: hope it helps
mark me as brainliest ^_^
Over the course of evolution, the bones of the animals undergo a gradual change in shape as well as in size. But still, two closely related animals have an identical overall layout of the bone.
What do you mean by Evolution?Evolution may be defined as a gradual process that involves changes or modifications in the members of the same or different species over a long period of time.
The bones of descent common ancestors reveal the evolutionary relationships among the animals. In relationship involves homologous and analogous structures.
The homologous structure reveals the structural similarity between the animals, while the analogous structures reveal the functional similarity.
Therefore, it is well described above.

During light detection in a photoreceptor, light directly causes what molecular change?.
During light detection, the light causes a retinal change from cis to trans conformation in regards to the opsin protein.
What is a photoreceptor?Photoreceptors are the name we use to refer to a specialized form of neuron cells. These cells are crucial in our ability to see, they allow vision. Their job is to receive and interpret light as information. They do this using a protein named opsin, as well as specific conformations of the retina, such as cis or trans, which change with the light.
Therefore, we can confirm that during light detection, the light causes a retinal change from cis to trans conformation in regards to the opsin protein.

Earthquakes also produce transverse waves that move more slowly than the p-waves. These
waves are called secondary waves, or s-waves. If the wavelength of a s-wave is 2.3 x104 m, and
its speed is 4.5 km/s, what is the frequency?
The frequency of the wave is 0.196 Hz
Speed of a waveThe speed of a wave is given by v = fλ where
f = frequency and λ = wavelengthFrequency of the waveMaking f subject of the formula, we have
f = v/λ
Since
v = speed of wave = 4.5 km/s = 4.5 × 10³ m/s and λ = wavelength = 2.3 × 10⁴ m.Substituting the values pof the variables into the equation, we have
f = v/λ
f = 4.5 × 10³ m/s ÷ 2.3 × 10⁴ m.
f = 1.957 × 10⁻¹ Hz
f = 0.1957 Hz
f ≅ 0.196 Hz
So, the frequency of the wave is 0.196 Hz

6. Multiple genes interact to determine the phenotype.
7. Two alleles are dominant, resulting in offspring that show both phenotypes.
8. One gene has several different forms, resulting in more than two phenotypes.
9. Two alleles are neither completely dominant nor completely recessive, resulting in a phenotype that is a combination of the two
Answer:
6.polygenic traits
7.codominance
8.multiple alleles
9.incomplete dominance
Explanation:
because i did it in savvas and i got it right.
The phenotype of an organism is influenced by the interactions of several genes. This implies that the organism's physical traits are governed by the interplay of several genes that it received from its parents.
When two alleles, or gene forms, are dominant, the dominant allele determines the phenotype of the progeny. This means that even if the other gene is recessive, the progeny will exhibit both traits if one of the alleles is dominant.
Sometimes a gene can take on several forms, producing more than two phenotypes. It is referred to as polygenic inheritance when more than one allele of a single gene affects the phenotype. Other times, two alleles are neither fully dominant nor fully recessive.

If a srna is bound to the ribosome binding sequence of a mrna coding for an enzyme in a bacteria, what effect will this have on the amount of enzyme in this cell?.
If an sRNA is bound to the ribosome binding sequence of an mRNA coding for an enzyme in a bacteria, it will reduce the amount of enzyme.
What is an sRNA?A small RNA (sRNA) is a short sequence that binds to target mRNAs by base complementarity and thus reduces gene expression.
These sequences (sRNAs) can efficiently block prokaryotic translation in order to reduce the amount of protein.
The sRNAs have fundamental regulatory roles both in bacterial translation and protein production.

How can you relate the structures
to those of bryophytes in terms of evolutionary trend
Answer:
Because ferns and fern allies posses true vascular tissues, they can grow to be much larger and thicker than the bryophytes.
Bryophytes mark the transition to land and the origin of vascular plants, and hence, link the seed and vascular plants to their algal ancestors.
Molecular phylogenetic studies conclude that bryophytes are the earliest diverging lineages of the extant land plants. They provide insights into the migration of plants from aquatic environments to land.What is evolution trends?Evolutionary trends, whether macro evolutionary events across higher taxa and large spans of geologic time, or more circumscribed events within smaller clades, have long played a prominent role in evolutionary theory.
The identification of trends in the history of life has been used as evidence for the increasing adaptions of life, for evolutionary progress, and more recently as support for selection at multiple levels.To know more about evolution here
