Answer:
1. Cells are composed of chemicals and both the structure and function of cells are regulated by the basic principles of chemistry. true
2. Scientists have successfully sequenced the entire genome of humans but have not yet sequenced the entire genome of any other species. false
3. Living systems are the most complex chemical systems on earth. true
4. Living systems are governed by the same principles of chemistry and physics that govern non-living systems. true
5. Living organisms contain unique chemical elements which are not found in non-living systems. false
6. An input of energy is required to maintain the complexity of living systems. true
7. The energy conversions that take place in living systems are governed by the same laws of thermodynamics that govern non-living systems. true
Explanation:
Cells are the basic unit of life which differentiate a living thing from a non- living thing. Although a living system, is made of the same chemical elements from which a non-living t=might be made, yet they are different from the non-living things as living things carry out the seven basic principles of live.
All living things carry genetic material from which their genome is made. Scientists have currently been able to sequence the genome of humans as well as many other organisms.
Seedless plants produce spores.Spores can develop into an adult without fusing with another cell.Seed plants produce seeds.Seeds are formed when the female reproductive structure matures; this occurs after fertilization.
That is the answer (:
Reproductive system and it's functions
When a person is anxious or fearful, the autonomic nervous system shunts blood away from peripheral veins to the core of the body - TRUE
- Sympathetic stimulation of blood vessels causes arteries and arterioles (resistance vessels) to constrict, increasing vascular resistance and reducing distal blood flow.
- The increased vascular resistance that results from this across the body raises arterial pressure.
- When our bodies shift into superman mode, the second signal is transmitted to the hypothalamus, where it activates our autonomic nerve system,
- which is in charge of the fight-or-flight impulse.
- Our bodies receive an adrenaline boost as well as an increase in heart rate and blood pressure. When you are afraid, you get that rush.
