Answer:
Feeling sick. People with advanced cancer often have problems with feeling sick (nausea) or being sick (vomiting). These can be caused by treatment with chemotherapy or radiation therapy, cancer growth, blockage of the bowel or the location of the cancer.
Explanation:
Answer: variation, reproduction, and heritability.
Explanation: Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.
Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.
<span> RNA
ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information. I hope that this helps you out!!!

The answer to this question is letter C. <span>The organism evolved during identification.
</span>A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. He was not able to identify the insect because t<span>he organism evolved during identification.
</span>
Choices to this question are:
A) The scientist must have made a mistake.
B) The insect might be an unknown variation or a new species.
C) The organism evolved during identification.
D) The dichotomous key had to many questions.
Answer:
- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Explanation:
Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.
