Answer:
Each component is in balance with the other components. As long as the components are in balance, the ecosystem can remain stable and healthy. Ecosystems may remain stable for many years if the different components are balanced.
Answer:
D. The nerves exit the central nervous system in the head and from the lumbar spine.
Explanation:
The preganglionic neurons transmit the nerve impulses through the cranial or spinal nerves that arise from the brain, to the postganglionic neurons from where the nerve fibers that relay these nerve signals to the different viscera and effector organs, located along the spinal cord
Answer:
Yes.
Explanation:
Yes, this type of genetic engineering should be pursued in order to avoid decrease in death through infections or diseases as well as increase the production of milk and meat of that animals. With this genetic engineering, organisms have high resistance to diseases which decrease the cost of antibiotics. The positive effect of this genetic engineering is the increase in the resistance that leads to good health as well as productivity of organism.
Drinking through a straw shows fluid flowing from high pressure to low pressure in 2 ways. The first is how it shows high pressure as you stuck on the straw. This increases the pressure and brings the fluid to your mouth. If this pressure is kept you can successfully pick up the straw filled with water and have none come out. This demonstrates low pressure when you stop ducking and the fluid falls back down the straw into your cup.
The order in which the earliest organisms evolved -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates
On the earth, various kinds of organisms evolve at different geological times, and on their evolution, they consider the oldest or youngest organisms:
- Archaebacteria and bacteria was the oldest living organism on earth was, they lacked a membrane-bound nucleus and cell.
- The protists evolved after the bacteria, they were multicellular prokaryotic organisms.
- Fungi and the shell-less invertebrate, much-developed organisms in terms of body organization and structure. These have membrane-bound, well-defined cell membranes, and a nucleus. They even had a tissue level of organization.
- Green algae evolve after protists which belong to the division Thallophyta of the plant kingdom. These are photosynthetic as they have chlorophyll in the cell.
- Shelled Invertebrates are the youngest organisms that evolved recently among these.
Thus, the correct order is -
- Archaea and bacteria
- Protists
- Fungi and shell-less invertebrates
- Green algae
- Shelled Invertebrates
