Answer: B
Explanation: So air, like most other substances, expands when heated and contracts when cooled. Radiation cooling occurs when air near the ground is cooled by the Earth's surface losing heat by radiation.
Answer: The two possible explanation for the outcome are as follows:
Explanation:
1. The bacterial DNA in the pellet was not completely isolated properly, therefore, no fluorescence was observed in the pellet under the exposure of UV radiation.
2. After 3 hours of induction with the IPTG and labeling with the G3. The IPGT might not be able to bound to the bacterial DNA that could show response of fluorescence in the ultraviolet light.
Answer:
Vertebrates contain nervous system which is highly specialized organ.
Explanation:
The nervous system is the complex system in the vertebrate body which is composed of central nervous system that contain brain,spinal cord and peripheral nervous system which contain cranial nerve, spinal nerve,involuntary nerve etc.
The nervous system contain neurons that mainly transmit signal to the different parts of the body.
The peripheral nervous sytem contain somatic and visceral part.
The grey matter and white matter are the 2 areas in vertebrate nervous system.
It would more likely to be pollinated by insects.
This is because the bright color of the petals can attract insects towards the flower thus sticking some pollen grains and transfer them to the stigma (female part of flower).
On the other hand, the color of petals do not really have effect on the wind pollination. Therefore this explains why wind pollinated flowers usually have small or dull colored petals.
Because tropical levels used to be broken because temperatures hasn't varied in the years and history of global temperatures and history.
