Answer:
FALSE
Explanation:
Papillary muscles are found in the bottom chambers of the heart and attaches to the tricuspid and bicuspid valve through tendons to facilitate blood flow during systole. It also prevent prolapse. These muscles contract before the contraction of ventricular muscles (or before the contraction of ventricles) by pulling chordae tendinae till the ventricles are relaxed. This helps in preparing the valves for high ventricular pressure
Hence, the given statement is false
Answer: 1: Environmental effects
2: High Cost
Explanation:
1 Environmental Effects
Power farms on shore that are visible from land may cause conflicts with tourism and local acceptance. Due to this, coastal installations and facilities on land has to meet higher restrictions in terms of size and location.
We don’t yet know exactly how wave power affects sea life. We will hopefully in the next following years have more data in this area.
2 Costs
Wave power is in very early stages of development, which makes speculating on costs harder. Wave resources, connections to the power grid and the lifespan of the technology are just a few factors that result in different costs for different projects. Of these factors, the lifespan is the most uncertain one, since this is a relatively new technology and we are lacking data on how long these wave power inventions realistically can operate.
At the moment, the costs of wave power are generally very high. These power plants cannot be developed without sufficient funding from the governments. On the other hand, renewable energy is the future, and the costs are expected to drop when larger facilities are up and running.
Many of the parts that are involved in wave power generation require regular maintenance. The fact that some of these parts are under the water does not make it any easier – or cheaper for that matter.
Answer:
All living things have DNA within their cells.
Explanation:
It would be the same cause dehydration is letting out water in the cell, just like the cloud would release all the rain when it rains
Answer:
Explanation:
The living material of most organisms is organized into discrete units called cells, and the study of their features is known as cytology. Cell biology is the study of cells—the fundamental units of structure and function in living organisms. But I don't know what the UAE is contributing to study of cels
