Answer:
(A) less binding of substrate
(B) won't follow the lock-and-key pattern of enzymes binding
Explanation:
Answer:
b. False
Explanation:
A scientific theory must have strong support from testable facts that are confirmed (or rejected) by observational and/or experimental procedures. The scientific method is a rigorous process that consists of arising a conjecture (hypothesis) which can be subsequently used to make predictions from its logical consequences, and finally to obtain information from empirical observations/experiments in order to obtain a conclusion about the veracity of the scientific claims (i.e., a hypothesis must be testable). In consequence, a scientific theory can not be based only on 'light' conjectures, but trustworthy observational data from the real world.
Answer:
Air temperature
Explanation:
Air temperature is being described by Jade according the properties highlighted.
The degree of hotness or coldness of a body is known as its temperature.
- As you go higher it becomes cooler. The surface causes the warming of the air around.
- With height, the surface is distant from the body of air.
- On summer days, air temperature is higher due to more insolation.
- Weather maps gives a good description of air temperature from places to places.
Answer:
Due to mutation.
Explanation:
The genotype and phenotype of circled offspring is different from the non-circled offspring because it has different genetic makeup, that is responsible for its different color. The change in the circled offspring's genotype was caused by a mutation. Mutation is a change that occurs in the DNA sequence, or genetic makeup of an organism due to mistakes when the DNA is copied or environmental factors such as UV light and smoke etc.
Answer:
d. to protect the end of a DNA molecule
Explanation:
Telomeres are like the protective shields of our cells' DNA.
Its name, of Greek origin, literally means "final part", and the telomeres are that: the ends of the chromosomes, something similar to the plastic tips of the shoelaces.
But they are very repetitive and non-coding parts of DNA: their main function is to protect the genetic material that carries the rest of the chromosome.
As our cells divide to multiply and to regenerate the tissues and organs of our body the telomere length is reduced, and so over time they become shorter.
When the telomeres finally remain so small that they can no longer protect the DNA, the cells stop reproducing: they reach a state of old age or old age.
Therefore, telomere length is considered a key "biomarker of aging" at the molecular level, although it is not the only one, and in recent years it has attracted the attention of numerous investigations.
