Answer:
An identical setup but replacing the enzyme with an equal volume of water
Explanation:
When carrying out any experiment, it is important to set out a control in order to increase the reliability of the data and results.
The control minimizes the effects of variables other than the independent variable.
In the above experiment, starch has to be eliminated and replaced with water. Water does not have starch hence the digestive enzyme being tested will not have any effects making the data and results from the experimental group reliable.
Answer: The Central Nervous System and The Peripheral Nervous System
Answer:
3. Rocks erode and sediment is deposited.
4. No sediment is deposited over a long time.
Explanation:
An unconfomity is a break in stratigraphic record of a place usually as a result of non-deposition or erosion.
In a sequence of sedimentary rock strata some surfaces called unconformity surfaces gives clues about the depositional history of a particular place. During an unconfomity, there is usually no sediment deposition and when deposition resumes, the underlying rocks and the new ones will not share the same attribute especially by age. Unconformity can also be as a result of erosion of a sequence.
In the case of non- conformity, a sedimentary rock is deposited above an igneous or sedimentary rock. Option 5 is a simple example of an igneous intrusion called a sill. It is not unconformity.
Answer:
Recombinant DNA can replace a gene in an animal’s genome.
Explanation:
The molecular cloning process involves in creating Recombinant DNA. This DNA is used to replace or replicate any specific gene. This is done by the process of PCR to replicate it directly.
This formation is done in the presence of a vector. This method is used in the field of veterinary office, pharmacy and many more. It has the ability to replace the gene of an animal’s genome.
Answer:
It has an anterior and posterior face. The greater tubercle serves as attachment site for three of the rotator cuff muscles – supraspinatus, infraspinatus and teres minor – they attach to superior, middle and inferior facets respectively. The lesser tubercle is much smaller, and more medially located on the bone
