The cell was discovered in 1669 by the English scientist Robert Hooke when looking at a piece of tissue in a two-lens microscope. Hooke was able to visualize small cavities in the experiment piece, then naming such cell cavities.

Only a century and a half after the discovery of the cell, that the Cell Theory was launched, replacing the theory of spontaneous generation (or abiogenesis).

Before that, many scientists were already busy understanding the structure and functioning of the cell, generating knowledge that became fundamental to the development of biology, specifically cytology, a branch of science that studies the structure, functions and development of cells.

Which sequence represents the correct order of levels of organization found in a complex organism?

icang [17]

Answer:

C is the answer.

Explanation:

Organelles (the smallest in this situation) are what you can find inside a cell (example: nucleus, mitochondria, etc..).

Cells are what make up tissues (such as muscles).

Tissues make up organs (such as the heart) and organs make up organ systems (such as the circulatory system).

Construct an explanation to predict the type of symbiotic relationship that exists between the hippo and oxpecker birds?

Allisa [31]

<h2>Answer:</h2>

<h2>The hippopotamus and the oxpecker bird are in a mutualistic and parasitic relationship. This is because the oxpecker bird gets food and protection from the hippopotamus. However, the bird gets food by making little cuts in the hippopotamus to obtain insects. This isn't entirely harmful to the hippopotamus though.</h2>
