According to the endosymbiotic theory, why was it evolutionarily adaptive for the larger, eukaryotic host cell to keep the engulfed bacterium that became the mitochondrion, rather than digesting it as food?

Which of the following characteristics is true of all protists?

Which are evolutionarily more closely related?

Polydactylism is a dominant trait that results in extra fingers and toes in humans. A normal number of digits (10 per hand and foot) is a recessive trait. A polydactyl man marries a woman with 10 fingers and toes. They have a child that has a normal number of digits. What are the genotypes of the married couple?

We see the emergence of true roots and true leaves (macrophylls) in which group of plants.

_______ is a process of nuclear division in which the number of chromosomes is halved during gamete formation.

Nearly all mushrooms are made up of this group of fungi.

During transcription in a eukaryotic cell, a segment of DNA known as a gene opens up, and a copy of it is made, called a messenger RNA (mRNA). The mRNA leaves the nucleus through the .  Once it leaves the nucleus, the mRNA enters the organelle adjacent to the nucleus, known as the .At this point, the mRNA is recopied into tranfer RNA (tRNA). In the process of translation, the tRNA becomes attached to the and synthesizes a protein. That protein gets packaged up and leaves through a circular organelle, know as a  and travels to the cis-face of the  , where the protein is modified, stored and eventually leaves from  the trans face. The protein is used within  the cell and eventually loses its functionality and ends up being digested by a circular organelle, the  in a process known as phagocytosis. 

Mendel conducted a controlled cross between pure lines purple flowered pea plants and pure line white flowered pea plants. All of the resulting hybrids from this cross developed purple flowers. Which of Mendel’s Principles does this illustrate?
