Scientists are using genetic engineering to develop a wheat crop that is resistant to a particular kind of moth. How would they

determine if the plants are moth-resistant?
Biology

Ivanshal [37]2 years ago

Answer:

Moth populations should be monitored in both, normal wheat and engineered wheat

Explanation:

Genetically engineered wheat crop means that the genome of the wheat is being manipulated by the techniques of biotechnology. Gene for the resistance to moths is introduced into wheat in order for plant to become protected. Determination of resistance should be performed via monitoring of control group (normal wheat, not resistance to moth) and engineered wheat (potentially resistant) and their comparation. Moth population should be decreased in the resistance plants.

What is a biological tropism?
kondor19780726 [428]

Answer:

A

Explanation:

Living organisms adapt to their moves and positions in response to the environmental changes for their protection or to their advantage. When an entity reacts to the changes in its surroundings, it is referred to as stimulus while the reaction to the stimulus is referred to as a response. Common stimuli are sound, light, air, heat, smell, taste, water and gravity.

Think of burning your finger of fracturing your bone without any pain sensation. It may certainly sound like a superpower or an ideal situation, however, when it comes to the standpoint of survival, it can be disastrous.

It is a characteristic behaviour of living entities to respond to stimuli with the intervention of the Nervous System. It is an organ system ascribed to send signals from the spinal cord and the brain throughout the body and then back from all the body parts to the brain. Neuron acts as the mediator and is the basic signalling unit of the Nervous system.

Pain is the body’s way of letting us know that something is not right. It can prevent further injuries or push us to seek medical attention. Moreover, all of this is possible because humans can respond and react to stimuli due to control and coordination among the various organs and organ systems.

Control and Coordination in simple multicellular organisms take place through only the Nervous system which coordinates activities of our body. It is the control system for all our actions, thinking, and behaviour.

Which condition of volcanic magma would mostly like cause an explosive, destructive eruption?
Irina-Kira [14]
The answer is the option "c"
The eruptions are caused by an accumulation of gases that press under a volcano.
The molten rock continues to generate upward pressure but can not advanced; this causes that its force increases with the passage of time, since it continues accumulating hot gases trying to come to the surface.
Finally, the surface yields and a volcanic eruption occurs.
