Without the discovery of magnetic reversals recorded on the ocean floor, scientists
A. could not confirm the usefulness of sonar
B. could destroy the hypothesis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents.
Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.
Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.
The study of a living being is called biology.
The correct answer is C.
Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents because magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.
Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rhythm of the magnetic reversal rate. Therefore the discovery of magnetic reversals is important to identify the mechanism for moving continents.

Some villagers plan to remove the trees from this hillside.
Doing this could damage their environment.
a ) Suggest one immediate problem for the animals that live on the hill.
b ) Suggest one problem that could arise during the rainy season.
Answer:
1) Deforestation has real consequences for animals. The most serious impacts of deforestation on animals are listed below. #1 Habitat loss Deforestation can lead to a direct loss of wildlife habitat as well as a general degradation of their habitat.
2)When there is less soil stability because of the disadvantage of erosion, the risk of a flooding event occurring during the rainy season increases dramatically. Poor water absorption levels make it easier for higher accumulation levels since the trees are no longer present to take up the extra moisture.

A. The sister chromatids separate.
B. Spindle fibers attach to the chromosomes.
C. Haploid cells are formed.
D. The nuclear envelope reforms.
Answer:
A
Explanation:
the sister chromatids separate
After the separation of homologous pairs, the sister chromatids are subsequently separated during meiosis II.
What is Homologous pair?Homologous pairs may be defined as those chromosomes which are very identical to one another and have the same size and shape.
In meiosis I, the separation of homologous pairs occurred. After this process, the sister chromatids are separated in meiosis II.
This separation leads to the production of a total of four products having the half number the chromosomes as compared to the original cell.
Therefore, the correct option for this question is A.

Illustrate the significance of membranes with the example of viruses
Answer:
Cell membrane encloses all the cell organelles. In prokaryotes, membrane is absent and so membrane-bound cell organelles are also absent.
Significance of membrane can be explained with the help of viruses, as viruses lack cell membranes and that is why they require a host for living and uses the host's cell machinery to multiply.
Hence, cell membranes are important for living organisms to live and perform essential biological processes.

About thirteen different species of finches inhabit the Galápagos Islands today, all descendants of a common ancestor from the South American mainland that arrived a few million years ago. Genetically, there are four distinct lineages, but the thirteen species are currently classified among three genera. The first lineage to diverge from the ancestral lineage was the warbler finch (genus Certhidea). Next to diverge was the vegetarian finch (genus Camarhynchus), followed by five tree finch species (also in genus Camarhynchus) and six ground finch species (genus Geospiza). If the six ground finch species have evolved most recently, then which of these is the most logical prediction?
Answer: Firstly it should be noted that, the chances of hybridization between two ground finch species should be less than the chances of hybridization between two tree finch species. On this wise, their genomes would be more similar to each other than are the genomes of the five tree finch species. Secondly, they should be limited to the six islands that most recently emerged from the sea.
Thirdly, they should share fewer anatomical homologies with each other than they have shared with the tree finches.
Fourtly, their genomes should be more similar to each other than are the genomes of the five tree finch species.

Which of the following correctly describes Anaphase?
A. Mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell.
B. Chromosomes split and move to opposite sides of the cell, the cell elongates
C. Centrioles move to opposite sides of the cell, nuclear envelop dissolves, chromosomes form
D. The Cytoplasm splits, forming two daughter cells
Anaphase is the phase of the mitotic and meiotic cell division. In this phase of the cell division, chromosomes split and move towards the opposite poles. Thus, option B is correct.
What is anaphase?Anaphase is the third stage of cell division, preceded by the prophase and the metaphase. In this stage, the chromosomes aligned before start splitting and move towards the opposite poles of the cells. This causes the cell to elongate and prepares itself to divide in the next step.
Therefore, in anaphase, the aligned chromosomes start splitting.

Explanation:
What are emergent properties?
Answer:
Emerging properties may arise by transient interactions such as individual organisms building a population. Human interaction in populations leads to the emergence of language, poetry, musical composition, and art. When populations of different species interact, communities form. Many emergent properties are the result of interactions between species in communities.
Emergent properties are characteristics of a system that do not exist in any of its constituent parts individually but originate as a result of interactions between those parts.
What does the characters indicate at ?These characteristics are frequently intricate and challenging to forecast. Emergent characteristics are a crucial idea in several disciplines, including physics, chemistry, and biology.
Emergent qualities in biology can be observed in an organism's behaviour. For instance, a flock of birds' behaviour is an emergent characteristic of the individual birds that make up the flock.
The behaviour of the flock is a product of interactions among the individual birds and is not exhibited by any one individual bird. Similar to this, a school of fish's behaviour is an emergent characteristic of each fish.
Emergent features in chemistry can be observed in how molecules behave. An emergent attribute of a substance's individual molecules, for instance, is the substance's boiling point. The boiling point is not a property of any one molecule, but rather the outcome of interactions between the molecules.
Particle behaviour in physics exhibits emergent features. An emergent attribute of a material's individual particles, for instance, is the material's electrical conductivity.
The interactions between the individual particles produce the electrical conductivity, which is not a property of any one of the individual particles. As a result, emergent properties are characteristics of a system that develop.
