The process that connects glycolysis and the citric acid cycle is the acetyl CoA formation.
Answer:
A) They only replicate the same time as the larger chromosome.
Explanation:
- Plasmids are small, circular, double stranded DNA molecule, which can replicate independently from its chromosomal DNA.
- If plasmids are used for experiments, they are called vectors.
- Scientists use plasmids as tools for cloning, transferring and manipulating genes.
- They are distinct from chromosomes in being non-essential.
- Plasmids are sometimes present in archaea and eukaryotic organisms.
- Plasmids often carry genes that benefit the survival of the organism, such as by providing antibiotic resistance.
- They do not replicate the same time as the larger chromosome.
The answer is; A.
The sunlight is used in the photolysis of water in the light stage of photosynthesis. This breaks down the water molecule to H and O. The H is then used to reduce carbon dioxide to glucose in the dark stage of photosynthesis while the O is expelled. The chlorophyll pigment is significant in tapping this light energy for photosynthesis.
Answer:
Selectivity in choosing a mates
Geographic barriers separating subpopulations.
Explanation:
Selectivity in choosing a mates is a factor in which individuals can mate with each other. Some individuals tend to choose a sexual mates that posses some traits or characteristics that attract them to each other and because of the observable character, similar individuals attracted to each other mates.
Geographic barriers separating subpopulations is another factor that make similar organism or individuals to mates.
When there is geographic separations or demarcation between individuals in a species and they are separated from other subpopulations .. They tend to mate with each other in the same geographic location and cannot mate with other subpopulations that is outside their own geographic location. These is common in animals.
The correct answer is option 4, that is, muscle cells require more energy, so they have more mitochondria in comparison to the skin cells.
Mitochondria are the powerhouse of the cells. The synthesis of ATP takes place in them, that is, the energy currencies of the cell. The cells of the muscles need to work hard and thus require ample energy, for this, they need more concentration of mitochondria to generate a high energy yielding ATPs.
