Ivanshal [37]3 years ago
5 0

Answer:

Lactose present, glucose absent.

Explanation:

Lac operon may be defined as a cluster of genes that regulate the metabolism of lactose in bacteria. The bacteria always prefer glucose if both glucose and lactose is present in the medium.

The conditions that causes the maximal expression of lactose is the presence of lactose and absence of glucose. This is due to the action of catabolite activator protein and cyclicAMP.

Thus, the correct answer is option (1).

WINSTONCH [101]
The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²

Volume = l³
Volume = (100 x 10⁻⁶)³

Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴

The process by which ions join to reform the solid is called dissolution
mestny [16]
I believe the process by which ions join to reform the solid is called precipitation. It is a process in which ions leave a solution and regenerate an ionic solid. For example; Ag+(aq) + Cl-(aq) = AgCl (s). Dissolution on the other hand is the process in which an ionic solid dissolves in a polar liquid; it is the opposite of precipitation.

State two ways in which endocrine glands and exocrine glands differ.
denis-greek [22]

Answer:

The two major differences lies in the function and support system.

Explanation:

The two major differences between an endocrine and an exocrine system are as follows –  

a) An endocrine system releases its produce (hormones) into the connective tissue i.e blood while the exocrine system releases hormones directly into the ducts so that it could reach the targeted tissue directly.  

For example – the Adrenal gland is an endocrine gland that secretes adrenaline directly into the blood. The salivary gland is an exocrine gland that releases its produce into the collecting duct leading to mouth. However, Pancreas is both endocrine and exocrine gland.

b) The endocrine system cannot work alone therefore it works in coordination with the nervous system to control actions and balance the body. However, the exocrine system works independently
