If a molecule of DNA has 200 pairs how do the DNA molecules fit into the cell?

DNA is able to fit into a cell because of its shape. DNA is a double helix that can bend and twist in all sorts of directions. An easier example to visualize is a spaghetti noodle in a bowl. Stretched out straight, it wouldn’t fit in the bowl, but once coiled or twisted up, it would conform to the shape of sand bowl. Well, DNA can coil up just like a noodle can, which gives it the ability to become compact enough to fit into the nucleus of a cell. The way DNA molecules can all fit into the cell is because they coil around histone proteins, which once in a tight enough coil, become nucleosomes which can stack to then become chromatin. That is how about 6 feet of DNA can be squeezed into a microscopic cell.

erma4kov [3.2K]
The number of green bodied insect would probably increase in the grass habitat. The insects that are green would be harder to spot by predators and therefore more likely to survive and produce offspring. The process of natural selection would favor the green color of the body and the future generations will have an increase in numbers of green bodied individuals over the tan bodied individuals.

Describe the tolerance range of temperature of a named terrestrial animal​
frez [133]

Life is found almost everywhere on Earth, but it is not distributed evenly around the planet. Different species are found in different areas; some species have overlapping ranges, others do not. Each species has a set of environmental conditions within which it can best survive and reproduce. Not surprisingly, those conditions are the ones for which it is best adapted. Many different physical, abiotic (non- living) factors influence where species live, including temperature, humidity, soil chemistry, pH, salinity and oxygen levels.

7. What causes greenhouse gasses to absorb heat when gasses like oxygen do not?
Scilla [17]

Answer:

Hope the below helps!

Explanation:

Greenhouse gases (such as methane, carbon dioxide etc) have lots of vibrating particles. These molecules eventually release radiation, which travels up Earth's atmosphere (because warm air rises), is trapped and adds to the greenhouse gas effect.

Oxygen and nitrogen don't interfere with infrared waves in the atmosphere. That's because molecules are picky about the range of wavelengths that they interact with.

I have attached a diagram that shows the greenhouse effect. It might help to visualise this.
