Answer:
The changes I observed in the moth populations result from the best-hidden moths surviving and reproducing, passing on their colors to their offspring. Why? Because individuals NEVER evolve, populations do. The second option fits best with Darwin's theory of natural selection, in which he stated that individuals with the most favorable traits are the ones to survive and reproduce, thus passing their traits onto the future population. The first choice incorrectly believes in Lamarck's theory of evolution in which he incorrectly believed that individual organisms in the population developed a trait that would help them survive (e.g. longer necks in giraffes).
Food cooking is an example of an endothermic reaction, because removing the source of heat would cause the reactions to stop
Answer: Option D
<u>Explanation:</u>
Cooking food is an example of endothermic or the heat-absorbing reaction where heat is absorbed by the system from the surrounding. Food is cooked by absorbing heat from the surroundings. Hence the temperature of the surrounding decreases.
Now when the source of heat is removed that would cause the reactions to stop. In an endothermic reaction an external heat is required for the reaction to proceed. Hence when the heat is removed and as the product is not that stable it is liable to stop the reaction.
Climate change and biodiversity are two completely different things. In some areas, climate change will increase biodiversity, allowing more species to live in certain climates, but it will make some species lose their habitats. Biodiversity helps ecosystems thrive, and generally keeps things in balance. However, introducing too many species in an area can cause increase competition for food, risking predators of different species to kill one another off. Both climate change and biodiversity can be good and bad.
Answer: C. It can help some species and hurt others.
Venus is often called the sister planet of Earth because of its size, mass, and what its material its made of.
Answer:
The correct option is D) All of the answers are correct.
Explanation:
The walls of the capillaries are thin due to which the processes of diffusion and filtration becomes lot easier in them. Gases such as oxygen and carbon dioxide cross the capillary walls through diffusion processes. As the walls of the capillaries are much thinner than that of veins and arteries hence. the processes of filtration and re absorption occur easily through them.
