Answer:
The correct answer is - they convert the energy stored in organic compounds.
Explanation:
Mitochondria is a very important cell organelle in eukaryotes as it produces energy and therefore, known as the energy center of the cell. Mitochondria produces the energy with the help of the process known as cellular respiration.
Cellular respiration takes place inside the mitochondria in order to convert organic compounds in the carbon dioxide and water and release a high amount of energy.
Answer:
Vertebrates have a skeleton inside them.
They have an internal skeleton made of bones.
endoskeleton - the internal skeleton; bony and cartilaginous structure (especially of vertebrates)
Explanation:
An endoskeleton is a skeleton found within the interior of the body; it provides structural support and protection for the internal organs and tissues of an organism. Endoskeletons can take several forms, and can differ in complexity, shape and function, depending on the requirements of the animal. Most vertebrates have an endoskeleton, which is comprised of mineralized tissue in the form of bone and cartilage
answer :c
Characteristics that are always present in living organisms are Metabolism, Cells and Reproduction.
The answer is D.
hhhhhhhhhhhh
Chromosomes actually duplicate in the S phase of interphase. Interphase is split into three phases, G1 phase, S phase and G2 phase. S phase is the synthesis phase, which is when DNA molecules (chromosomes) double.
Some concept fix will happen in university, because in university level, we say that chromosome never doubles, it is the amount of DNA molecule that doubles. Also, interphase is part of the cell cycle, but not mitosis (IN UNIVERSITY LEVEL, so don't worry about it)
But for high school, the answer to your question will be interphase.
