Answer:
Various scientists describe asteroids in different ways:
- Some scientists consider it to be rocks which orbit around the sun.
- Other consider it to be small planets.
The majority of the scientists agree that asteroids might have come into existence at the time of solar formation. The parts which broke down during the formation of the solar system resulted in the formation of asteroids.
<u><em>Scientists believe that asteroids might not have a major function in the universe but studying them would be of great benefit. This is because as they are parts broken from the solar system, exploring them will let us know about some unknown features of the other solar system bodies. </em></u>
Blubber is a thick layer of fat (adipose) tissue. Animals store extra digested food in the form of adipose tissue, which contains molecules called lipids.
Answer:
Explanation:
Botulinum toxin (Botox) is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species
Botulinum toxin commonly acts by binding to high-affinity recognition sites on the cholinergic nerve terminals and decreasing the release of acetylcholine, causing a neuromuscular blocking effect. Through this mechanism, muscle movement is inhibited in the area it is injected to.
D has a positive charge and located in nucleus
1. fossils and chemical isotopes found in sediments and glacial ice
By studying the type of climate fossilized species preferred global temperature trends can be inferred. The changes in the concentration and type of isotopes are also an accurate measurement tool of these changes.
2. decrease in mortality because winter is warmer
The phenomenon known as global warming will bring more extreme weather. Thus, it is possible for some winters to be very cold and summers be very warm.
Even with warmer winters, the mortality will not decrease. Without a snow cover, pests such as mosquitoes and pathogens will thrive and live for longer periods of time. Thus, the spread of diseases will increase which will lead to potential increases in mortality.
3. all activities by humans affecting the Earth and its biosphere
Anthropogenic activities are all activities by humans affecting the Earth and its biosphere.
4. decline in sea ice
The main cause behind declining numbers of polar bears is the diminishing size of the sea ice. The bears use the ice as hunting ground where they stalk seals.
