Answer:
Fossils are usually named based on the following conditions-
- the location in which they are found
- named after the scientist who discovers it
- the rock formation in which they are found
- They are given two names, the genus and the species
These fossils are again categorized into different groups depending on the similarity in terms of form.
These names of the fossils are important to the comparative anatomists because it helps them in doing the comparative study and understand the causes of similarities and dissimilarities in terms of anatomy and also helps in understanding the evolutionary process of these organisms. For example, the fossil named 'Ida' is the primitive fossil that was found to be almost completely preserved. This fossil helped in comparative studies with other fossil species in a number of ways.
Pseudopodia are temporary projections of the cell membrane of eukaryotic cells. And by temporary, it means that it is not a fixed structure. Single-celled organisms characterized by the ability to form arm-like protrusion that can be protracted or retracted are referred to as amoebae.
Answer: 70%, although that is an estimation because it is 71%
Answer:
Stem cells have the ability to divide <u>through mitosis</u> and produce unspecified cells. Stem cells can be developed into a required tissue because of their ability of <u>differentiation</u>.
Explanation:
A stem cell is a cell that is in an undifferentiated state. This means that it has not specialized in a specific type that carries out a specific function of that tissue, which does not imply that stem cells do not have their own function. The concept of stem cell is due to the ability to originate specialized cells from one or more tissues, depending on the degree of potency or plasticity it has. They are found in all multicellular living organisms. Their main characteristic is that by reproducing through the process of mitosis (they divide into two cells) they can form more stem cells or differentiate, that is, they become specialized cells, in such a way that they are essential for the renewal of cells in different tissues. and to repair them.
The answer is would be -- Clam shells found within the rock sample.
