Answer:
B. 25%
Explanation:
Assuming the trait for teeth size is represented by the allele A. large teeth size is dominant and will be represented by A while small teeth size will be represented by a.
Assuming that the population of 1,000 [piranhas are all heterozygotes and they crossbreed with one another:
Aa x Aa = AA, Aa, Aa and aa
The ration of piranhas with large teeth to that of the small teeth is 3:1 or 75:25.
Hence, about 25% of the next generation of the population is ecpected to have small teeth.
The correct option is B.
Black-crowned night-heron. This predator is adapted to hunt at night. In
the French Guiana this is one of the major night heron species with its
cousin the Yellow-crowned night-heron (Nycticorax violacea). Feeds
mainly on aquatic animals, including fish, amphibians and insects.
Coastal swamps.
Answer:
C, a decrease in metabolic activity
Explanation:
In times of drought, there would be a reduction in the metabolic activity of an organism.
- Most organisms found in very dry climates have adaptation to accommodate a period of drought.
- Water is essential for the metabolic processes in an organism.
- A deficiency of water will reduce these life activities.
- The organism can become inactive as a result of this.
Answer:Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Explanation:
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.
<em>by definition- a stem cell is an undifferentiated cell of a multi-cellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.</em>
an example
Stem cells have the potential to be whatever they want to be. Stem cells are able to develop into many different types of cells and can repair your body.
there are two types
adult stem cells and embryonic stem cells
