There’s supposed to be 9 on each side and 6 in the middle. Which one did I mess up that was supposed to be in Mitosis?
Genrish500 [490]
The incorrect one in the Meiosis category would be,

"Same number of chromosomes as the original cell." 

This is because the original cell would've had 46 chromosomes but the new cell only 23.

Determine the location of the electron transport chain inside the mitochondria
katrin [286]
The electron transport chain is located on the inner membrane of the mitochondria, as shown below. The electron transport chain contains a number of electron carriers. These carriers take the electrons from NADH and FADH2, pass them down the chain of complexes and electron carriers, and ultimately produce ATP.

is the following statement true or false? the mountain zebra ( equus zebra) and the donkey ( equus asinus) belong to the same sp
emmasim [6.3K]

False. The mountain zebra and the donkey do not belong to the same species.

<h3>What are species?</h3>

The species represent the lowest and narrowest taxonomic categories as far as the classification of living organisms is concerned.

A species represents a group of organisms whose mating will lead to the production of valid offspring.

Thus, no two different organisms can bear the same species name unless they can mate and produce fertile progenies.

What the mountain zebra and the donkey share is the genus name, not the species name. Different species of organisms can bear the same genus name as far as taxonomy is concerned.

What are the 3 things that all organisms are capable of doing? These are also known as the challenges of life.
disa [49]
<span>C) growing, processing nutrients, reproducing Let's look at the 4 options and see which makes sense. A) working, growing, eating food * Not so sure about all organisms being able to work. Also the eating food part seems questionable to be, depending upon how you define eating. After all, plants don't eat like you may consider eating. There's likely to be a better choice later. So consider this wrong for now. B) photosynthesis, reproducing, growing * There's an immediate problem with this choice. Plants do perform photosynthesis and are considered alive. But animals don't. So photosynthesis isn't something all organisms can do. So this is a wrong choice. C) growing, processing nutrients, reproducing * Can't see anything wrong here. An organism needs to grow. It has to process nutrients in order to grow. And if it doesn't reproduce, it will eventually die and leave nothing behind. So this is the correct choice. D) running, breathing, watching TV * This choice is wrong on so many levels. Trees which are an organism can't run, nor watch TV. So this is also wrong.</span>
