this step of intergrated pest management involves the use of pesticides to control pests and their damage​
goblinko [34]

The "control" step of intergrated pest management involves the use of pesticides to control pests and their damage​.

<u>Explanation:</u>

IPM have four steps, which is a sequence of pest control method. When the thresholds for surveillance, detection and intervention suggest the need for pest control and prevention measures are no longer efficient or usable, then IPM (intergrated pest management) initiatives determine the appropriate management system for both efficacy and risk.

Efficient, less dangerous pest controls, involving highly concentrated chemicals like pheromones to hinder pest mating or mechanical control like trapping or weeding, are selected first. If more analysis, detection and intervention thresholds suggest that less dangerous controls do not operate, then alternative pest control approaches, like targeted pesticide spraying, will be implemented.

Which statement is NOT true of acetoacetate and β‑hydroxybutyrate? They share a precursor with cholesterol synthesis. They can p
Arte-miy333 [17]

Answer:

The answer is B.

Explanation:

Acetoacetate and Acetyl CoA share a precursor with cholesterol synthesis which begins with Acetyl Coa but not β‑hydroxybutyrate.

Modifying other enzymes can be said for β‑hydroxybutyrate but not Acetoacetate.

They are not both produces from Acetyl Coa of fats. β‑hydroxybutyrate is produces from the acids with fats in the liver but the same can not be said for Acetoacetate.

However they both can be said to provide energy for the brain because they are both released into the bloodstream in the event of hunger or when the body/brain needs energy in a state of fasting.

I hope this answer helps.

which one of the following statements is not true of the helper t cell response? science philosophy of the vsc
sergeinik [125]

The fact that helper T cells produce antibodies is incorrect. T cells can stimulate B cells to make antibodies, but they cannot make them by themselves.

<h3>What is cell-mediated immunity?</h3>

Cell-mediated immunity includes B cells and T helper cells, both of which are important components of the adaptive immune system. Antigen-presenting cells (APCs) first activate helper T cells by showing them the antigen that is carried by them. After T-helper cell activation, it secretes some cytokines that further stimulate the cell differentiation of T cells and activate B cells. The B cell, after activation, makes antibodies that are required to kill the particular pathogen in the body.

Hence, the option that mentions that helper T cells produce antibodies is incorrect.
