Answer;
- 1.2 nM
Explanation;
-Smallest Km means highest affinity, can bind substrate better at lower concentrations. The relationship between rate of reaction and concentration of substrate depends on the affinity of the enzyme for its substrate. This is usually expressed as the Km (Michaelis constant) of the enzyme, an inverse measure of affinity
-Km is therefore, the concentration of substrate which permits the enzyme to achieve half Vmax. An enzyme with a high Km has a low affinity for its substrate, and requires a greater concentration of substrate to achieve Vmax.
A participial phrase starts with a participle, which is a verb + ing, for example - dancing. An infinitive is to + verb, for example, to dance.
Having this in mind, the sentence that uses both a participial and an infinitive phrase is C. <u>Annoying me into a rude awakening</u>, the alarm continued <u>to buzz</u> loudly in my ear.
Answer:
The major structural difference between chromatin and chromosomes is that the latter are more organized and condensed.
Explanation:
Chromatin is genetic material packaged into a complex by special proteins (histones). That complex is in the form of uncoiled structures, so chromatin fibers are long and thin. Chromatin structure is permissive to DNA replication, transcription and recombination events.
On the other hand, chromosomes are highly condensed structures of genetic material that are formed just before the cell division.
The plants URANUS and Neptune are known as the ICE GIANTS. These planets are the farthest away from the sun in the solar system.. They live just beyond the planet SATURN, at which point temperatures DECREASE drastically.
Isotopes are atoms of the same element with the same atomic number but different mass number. unstable atoms atoms undergoes radioactive decay. Therefore radioactive decay is the process by which unstable nucleus loss energy by emitting radiations such as beta , alpha and gamma particles.
The initial mass of radium-226 is 6 grams and the new mass is 0.375 grams therefore the number of half lives undergone are 0.375 = 6× (1/2)n where n is the number of half lives. (1/2) n = 1/16
therefore n= 4. Meaning the isotope radium-226 has undergone 4 half lives
1 Half life = 1600 years
4 half lives = 1600 years × 4 = 6400 years
therefore, the rock reached its closure temperature 6400 years ago and secondly when the rock was discovered it had 5.625 g mass of radon-222.
