Less stomata because stomata is the pathway through which water transpires. A cactus' habitat is much drier than normal tropical plants, therefore it would require less transpiration to survive. In order to lessen transpiration, they have less stomata.
Answer:
The correct answer is - 10³ seconds.
Explanation:
The nerve impulse is an electrical signal in which fluctuation in membrane potential occurs and forms an electrical signal that takes place that travels along the axon to the synapses.
Suppose a nerve impulse starts only when the first impulse ends according to the question so the one impulse last for the 10⁻³ second or 1 ms.
Thus, the nerve impulse fires per second will be equal to impulse generate in each second which is 1/10⁻³ = 10³.
Thus, the correct answer is - 10³ impulse per second or 1000 impulse per second.
Answer options:
- extraction and observation of DNA
- identification of ribose and deoxyribose
- recognition of RNA as DNA’s messenger
- construction of an accurate DNA model
Answer:
- identification of ribose and deoxyribose
Explanation:
Phoebus Levene was an American biochemist who studied the structure of DNA and RNA. He was able to isolate the sugars (ribose and deoxyribose) from the nucleic acids, which are an important part of their structure.
He also determined how the nucleic acid components combine to form the nucleotides, the basic building blocks of nucleic acids, and how the nucleotides combine in chains to form the polymer.
Answer:
Recent studies of the veterinary profession have established a need for training in various areas beyond those directed toward building competence and proficiency as a clinician. To address this need, a workshop was designed whose objective was to develop a detailed outline of a model curriculum that would encompass the skills, knowledge, aptitudes, and attitudes deemed essential for economic success in the veterinary profession. The model curriculum was created from comprehensive input provided by consultants and educators. Constraints for implementation of this curriculum are identified, and future directions are discussed.
