Explanation:
production of living organism from nom living matter is known as spontaneous generation.
Answer:
b) A parasite does not immediately kill its host.
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.
Answer:
B. Surgery
Explanation:
I am not entirely sure but based on the definition of selection pressure (which talks about how external agents affect the survival of an organism) surgery is does not meet the definition.
A tiger hunting a prey affects the survival of prey. Beginning of ice age is an environmental agent that can affect survival of organism that cant tolerate cold. Antibiotics are drugs that can kill bacteria thus lower their survival. Surgery can actually increase survival if some form of disease is being treated.
Answer:
Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
- sensory systems-detects ratios of glycolytic intermediates,
- global regulators-control the expression of genes that encode for enzymes.
