Please help asap the scientific name Canus nipponicus. To which classification levels does this scientific name belong?
Amiraneli [1.4K]

The correct answer is - C. genus and species.

The final scientific name of an animal represents two things, its genus, and its species.

The first name is the genus of the animal, in this case we have Canus. The second name is the species of the animal, in this case nipponicus.

All living organisms are classified in a same manner: kingdom, phylum, class, order, family, genus, species.

Since the name Canus reminds me a lot of Canis, I will take the wolf as an example:

Kingdom: Animalia

Phylum: Chordata

Class: Mammalia

Order: Carnivora

Family: Canidae

Genus: Canis

Species: C. Lupus

tresset_1 [31]

Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.

In which squares should the phrase “Green pods” appear?

1.A and D  2.B and E  3.A,C and D  4.A,B,C,D and E

Answer:

3.A,C and D

Explanation:

As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.

As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.

Which of the following is a scientific question the student might ask?
Neporo4naja [7]

Answer:

<em>The correct option is C)  How does sunlight affect a model of a biogeochemical cycle?</em>

Explanation:

A scientific question can be described as a question based on which a hypothesis can be made and observations and experiments can be performed. The results from these experiments and observations would account for the validation of a hypothesis. Hence, a scientific question should be a question based on which a hypothesis can be made and experiments can be performed.

In the option C, the sunlight might increase or decrease various processes of the biogeochemical cycle. We can hypothesize and perform experiments to get the results. Hence, it is a scientific question.

In hummingbirds feather color is incompletely dominant. A rather large population of hummingbirds has 396 red-sided individuals
GrogVix [38]

Answer:

a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557  x 2) = 1049 / 2420 = 0.433

b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557  x 2) = 1371 / 2420 = 0.567

c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557  x 2) = 649 / 2020 = 0.321

d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557  x 2) = 1371 / 2020 = 0.679

e) migration is gene flow  

Explanation:

Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).
