There would be an increase in dead matter and a lack of nutrients in the soil.
Decomposers break down dead matter, so without them there will be an increase.
They then return the nutrients from the dead matter to the soil, so there will be a lack of nutrients in the soil.
Examples of decomposers are mushrooms and earthworms.
<h2>Order of parts of a microscope
</h2>
First – ocular lens
Second – Body tube
Third – Revolving Nosepiece
Fourth – Objective lens
Fifth – Coverslip
Explanation:
Ocular lens: The lens present in the eyepiece at the top of the microscope, close to the eyes, through which a person looks through the microscope to view the specimen. Magnification of ocular lens in a compound microscope is usually 10x
Body tube: The tube that connects the eyepiece with the objective of the microscope for continuous optical alignment.
Revolving Nosepiece: The turret that holds the objective and revolves to select the objective lens according to its magnification
Objective lens: The objective lens is located above the specimen rack. Objective lens creates the primary image of the specimen viewed through the eyepiece. A single compound microscope can have more than two objective lens and their magnification ranges from 4x, 10x, 40x, 100x power.
Coverslip: The cover glass which covers the objective lens and prevent from touching the specimen
. This is the object directly above the specimen.
Answer:
Diseases that result from a homeostatic imbalance include heart failure and diabetes, but many more examples exist. Diabetes occurs when the control mechanism for insulin becomes imbalanced, either because there is a deficiency of insulin or because cells have become resistant to insulin.
- diabetes
- Blood oxygen content homeostasis.
- Homeostatic Imbalances of the Blood
- Plasma ionized calcium homeostasis.
- Arterial blood pressure homeostasis.
- Core body temperature homeostasis.
- The volume of body water homeostasis.
- Extracellular sodium concentration homeostasis.
Answer:
C. repressible
Explanation:
The trp operon in bacteria is a repressible operon. The regulatory gene codes for repressor protein. In the presence of tryptophan, the repressor (inactive) binds with tryptophan and gets activated. This active repressor attaches with operator and prevent polymerase to bind and thus inhibiting transcription of genes in the operon.
The mutant strain cannot attach to operator (trpO+) but it can make dimers. As the operator is mutated so it prevent binding of repressor to operator. Thus, expression of the trp operon is repressible.
