A chromosome consists of a single, double-stranded DNA molecule. Chromatids are two molecules of double-stranded DNA joined together in the center by a centromere. Chromosomes have a thin ribbon-like structure. Chromatids have a thin and long fibrous structure.
Answer:
a. Global warming
Explanation:
Solar energy is the form energy which uses the SUN as Its source. It is a renewable source of energy. Humans, through our activities, contribute to the gradual increase of the earth's atmospheric temperature, called GLOBAL WARMING. We contribute to this phenomenon posing threat to the environment's sustainability when trying to fulfil our day-to-day individual needs.
One of those activities is the burning of fossil fuels via cars, in industries, domestic households etc. The burning of fossil fuels results in the release of heat-trapping gases called Greenhouse gases e.g CO2, CFC etc. These gases are the major cause of Global warming.
Hence, Joe is trying to work on how solar energy can replace the use of other sources of energy that release these greenhouse gases into the atmosphere in order to curb GLOBAL WARMING.
N.B: Solar energy does not emit greenhouse emissions. It is the best and safest source of energy.
Answer:
the movement of hydrogen ions across a mitochondrial membrane is a correct answer.
Explanation:
- Chemiosmosis involves the movement of hydrogen ions across a mitochondrial membrane.
- Chemiosmosis is the hydrogen movement ions across the semipermeable membrane from the area of high concentration to lower concentration.
- Chemiosmosis function is to produce ATP through cellular respiration in the mitochondria this process is called oxidative phosphorylation and the ATP produce during the Chemiosmosis provide energy to the living cells.
