Easy points 1 suggest what the drug longmasterol might do to the body to affect reaction time 2describe the effect of longmaster
Semmy [17]

Answer:

4.Antagonistic muscles are muscles that have opposite effects to one another,As one relaxes, the other contracts.

5, This is to move bones in tandem to cause locomotion.As as one contracts, and the other relaxes, the bone is pulled and this shifts the position of the bone to cause locomotion.Note, a muscle cell usually pull in one direction.,

6. it lacks nucleus to have enough space for oxygen carrying molecules(haemoglobin)it has bi-concave shape to squeeze through tinny capillaries to reach tissues and have large surface area for oxygen carriage.They contain Oxygen carrying pigment Haemoglobin.

1.This is a stimulant that increases the rate of excitability by increasing the synaptic connection through increase in amount neurotransmitters, at synaptic junctions

2,This accelerate the rate of ageing.Leading to premature aging.it ,may affect the heart efficiency and the entire cardiovascular system at the long run.

3. After a period of time this may cause liver damage by blocking blood flows to the liver.It may also lead to inhibitory effect of detoxification activities of the liver.This leads to hepatic failure.

7. A state of matter can only be compressed at  the gaseous state.it can not be compressed at solid because the inter molecular forces are very strong and the molecules of solids are well compact. Molecules of liquids are not free neither, although their molecular force are weak, But the molecules can not be compressed, since they lack random motion.

8. This is due to the lattice arrangement of water molecules in ice, resulting in lesser density of ice compare to that of water. The lower density of ice makes ice to float when it freezes, however, it is the higher lattice arrangement in ice which makes it expand, compare to other liquids which makes it less dense and therefore floats.

10. This can be caused by the force that pull water through the mains to the pipes.it is measures in bars. Thus 1 bar is equal to the force per unit area lifting water to a height of 10 meters.

9. This is to generate a forward thrust, to overcome the aerodynamic drug.The propeller engine generate a thrust, which ensure a steady speed  large enough to overcome the drag

What does it mean when scientists say that living organisms share a universal genetic code?
lesya [120]
When scientists say they share a universal genetic code it means that all organisms it can mean either DNA as the main source of hereditary information in all life forms we know of  or more likely that all organisms we know of use a three base pair code for the synthesis of proteins, DNA produces mRNA. This mRNA is read three base pairs at a time by a ribosome and this is called the genetic code.

Explain Mercury is the planet closest to the Sun. Why does it get so cold at night?
alexdok [17]

Answer/Explanation: On Mercury temperatures can get as hot as 430 degrees Celsius during the day and as cold as -180 degrees Celsius at night.

Mercury is the planet in our solar system that sits closest to the sun. The distance between Mercury and the sun ranges from 46 million kilometers to 69.8 million kilometers. The earth sits at a comfy 150 million kilometers. This is one reason why it gets so hot on Mercury during the day.

The other reason is that Mercury has a very thin and unstable atmosphere. At a size about a third of the earth and with a mass (what we on earth see as ‘weight’) that is 0.05 times as much as the earth, Mercury just doesn’t have the gravity to keep gases trapped around it, creating an atmosphere. Due to the high temperature, solar winds, and the low gravity (about a third of earth’s gravity), gases keep escaping the planet, quite literally just blowing away.

Atmospheres can trap heat, that’s why it can still be nice and warm at night here on earth.

Mercury’s atmosphere is too thin, unstable and close to the sun to make any notable difference in the temperature.

Space is cold. Space is very cold. So cold in fact, that it can almost reach absolute zero, the point where molecules stop moving (and they always move). In space, the coldest temperature you can get is 2.7 Kelvin, about -270 degrees Celsius.

Sunlight reflected from other planets and moons, gases that move through space, the very thin atmosphere and the surface of Mercury itself are the main reasons that temperatures on Mercury don’t get lower than about -180 °C at night.
