Option A, geographic poles are defined by Earth's rotation, is the correct answer.

The rotation of the earth is its revolution around its own shaft. The direction of Earth's rotation is eastward. The North Pole of the Earth is the spot in the Northern Hemisphere where Earth's axle of revolution joins its surface. The South Pole is another location; where the axis of Earth's circumrotation intersects its facade, in Antarctica. The geographical poles of the North and South Poles of the Earth move a few meters over a period of few years.

The poles cannot move 10 km a year because they are connected to earth which moves way more than that

Leya [2.2K]

Answer:

A. Auxotroph 4. requires at least one nutrient for growth

B. Conjugation 1. requires cell-to-cell contact

C. Hfr 6. E. coli strain with Ffactor integrated into bacterial genome

D. Transduction 7. requires virus

E. F' 5. F factor that has picked up a piece of the bacterial genome

F. Transformation 3. uptake of DNA from external medium

G. Competent 2. capable of taking up DNA

Explanation:

Auxotrophs are those organisms able to synthesize organic compounds required for their growth.

Conjugation is the genetic transfer between bacteria through cell-to-cell contacts.

In bacteria, the Hfr chromosome is linearly transferred from F to F- cells.

Transduction is a genetic process where exogenous DNA fragments are introduced into another cell via a viral vector.

The F factor (fertility factor) is a bacterial plasmid that allows to transfer genetic information between donor and recipient cells during conjugation.

Bacterial transformation is the horizontal transfer of genetic material by which bacteria obtain DNA from its environment.

In bacteria, competence refers to the ability to take up exogenous DNA from the external environment.

Before a cell can enter cell division, it needs to take in nutrients. All of the preparations are done during interphase.<span> Interphase is a series of changes that takes place in a newly formed cell and its nucleus, before it becomes capable of division again. It is also called preparatory phase or intermitosis.</span>

slava [35]

Answer:

The correct answer would be D) tissue.

In biology, the level of organisation from simplest to complex level can be summarized as:

Organelles → cells → tissues → organs → organ systems → organisms → populations →communities → ecosystem → biosphere.

It is clear that tissue is organization level that exists between cells and organs.

When similar cells are assembled together to perform specific function, the assembly or this organization is said to be the tissue.

There can be different types of tissues such as muscle tissue, nerve tissue et cetera.

Similarly, tissues arrange themselves to carry out specific function in the form of organ.

For example, heart is made up of cardiac tissue.
