The principle of common descent helps explain why a.well adapted species have many off spring
b.conditions in an organisms environment ensure the organisms survival
c.birds and reptiles share a number of inherited characteristics
d. tigers are so different from cheetahs

Answers

Answer 1
Answer:

Answer:

The correct answer would be c. birds and reptiles share a number of inherited characteristics.

In evolutionary biology, the principle of common ancestors or descent explains how different groups of organisms share a common ancestor.

In other words, different groups of organisms are believed to evolve from a common ancestor.

The groups which share recent common ancestor share a number of common inherited characters.

The groups which share distant common ancestor share less common characters.

Thus, birds and reptiles share a number of characters as they have evolved from common descent or ancestor.
Answer 2
Answer: C.  birds and reptiles share a number of inherited characteristics

What part of the cell function as factories to produce proteins???

Answers

The production of a protein is called protein synthesis and this is splits into two parts 'transcription' & 'translation! I'm not sure how much depth you need so I'll be brief:
Transcription:
Occurs in the nucleus
The double helix unzips to leave one strand
The bases are joined by weak hydrogen bonds
The mRNA (messanger RNA) takes this onto the next stage as a copy of the bases has been taken!
Translation:
The copy is taken out into the cytoplasm
In the cytoplasm there are organelles called ribosomes
The ribosome reads the DNA
tRNA is involved in this
They are split into triplets ( three bases) which makes an amino acid & amino acids all code for a protein.
Hopes this helps!! :D

What is the function of eukaryote

Answers

it is a cell Organelles of Eukaryotic Cells Below is a list of organelles that are commonly found in eukaryotic cells. Organelle Function Nucleus The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA . Mitochondria Make energy out of food Ribosomes Make protein Golgi Apparatus Make, process and package proteins Lysosome Contains digestive enzymes to help break food down Endoplasmic Reticulum Called the "intracellular highway" because it is for transporting all sorts of items around the cell. Vacuole Used for storage, vacuoles usually contain water or food. (Are you are thirsty? Perhaps your vacuoles need some water!) Plant cells also have: Chloroplasts Use sunlight to create food by photosynthesis Cell Wall For support 
In general, cells (which include prokaryotic and eukaryotic cells) have a main purpose: to survive. In eukaryotic cells, their shapes often reflect their functions. For example, nerve cells have long extensions that reach out in various directions in order to allow the cell to send and receive nerve impulses. Another example is skin cells. Since skin cells are flat and plate-like, they help cover and protect the surface of the body. As organisms evolve into more advanced organisms, their cells become more specialized and eventually were unable to survive independently. Groups of cells that carry out a similar function is called a tissue. Groups of tissues that perform a particular job form an organ. Groups of organs that perform related tasks form organ systems. Finally, groups of organ systems combine to form an organism. In other words, prokaryotic and eukaryotic cells try to keep the organism alive.
