The possible scenario for singing traits in female birds will be about 26% in Generation 4 species
Explanation:
Singing trait have been common among both male and female birds and it is an ancestral traits. However, singing has been more sex-specific with male birds. Reasons for which birds generally sing are:
- To attract the mates
- While making nests and laying eggs
- For the young birds to recognize their parents
However, various studies prove that the singing trait in female birds is reducing with increase in non-singing female birds over the years due to evolutionary course.
Answer:
The correct answer is option A. "cell fractionation to study the function of specific organelles".
Explanation:
Cell fractionation is a scientific process used to study the function of specific organelles, which main idea is to fractionate the cells but preserving the individual function of the elements of the cell. Usually, the separation takes place by a centrifugation method. This methodology was developed to identify the location of the organelles within the cells, but nowadays is used to study its functions.
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.
Answer:C. Point, nonpoint
Explanation:
Point source of water pollution originate from a single source and the source of origin can be determined. Industrial and sewage drainage systems are the examples of point source pollutants. The source of pollutant is easy to detect and monitor.
Non-point source of water pollution the source of pollution remains undetermined. The pollutants may enter in water body through multiple sources. Hence, it is difficult to track back the source of single pollutant. Thus non-point source pollution cannot be clean and monitored.
