Answer: The immune system
Explanation:
The immune system is a complex network of proteins and cells that defends the body against infection or any invasion. The human defense system in the body is actually made up of entire organs and vessel systems like the lymph vessels. The immune system is made up of organs that control the production and maturation of certain defense cells.
Initially, all living things are subjected to attack from disease causing agents. Even bacteria, so small that more than a million could fit on the head of a pin, have systems to defend against infection by viruses. This kind of protection gets more sophisticated as organisms become more complex.
Answer:
Yes, the environment and the heritage both plays very crucial role in defining the evolution. But how? let's start it here.
Explanation:
- As per the Charles Darwin theory of natural selection, organisms that better adapt to changes can survive very well.
- For example In earlier times, snakes used to have limbs but they are just useless for them and they are not using those limbs so in next generations snakes have vestigial remnants of limbs.
- Another example we can study here is of mice, such as mice are nocturnal animals so they don't have vision capabilities and over generations they adapt a change due to their predatory nature and came with an affect of better hearing capabilities.
Answer:
Greenhouse gases are good because they keep the Earth warm. They trap the heat energy that is radiated from the Earth in the atmosphere. Without greenhouse gases, the Earth would have an average yearly temperature of 0 degrees Celsius.
Answer:
Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall. How do they figure it out? They get evidence from the sim and from video of an experiment to determine which organisms do cellular respiration.
Explanation:
Hope this helped you :D
Answer:
D
Explanation:
A geometric progression is multiplication by a number. In this case, it is 3.
If you take 4, multiply it by 3, you get 12. Multiply 12 by 3, you get 36. And so on.
