1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x
2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power.
3) So it doesn't gather dust and fog up the lense? that one should be self explanatory
<h2>
A change in one base of the gene sequence is known as point mutation.</h2>
Explanation:
Question 2 is incomplete.
3. A mutation that only affects a single nucleotide of nucleic acid is known as Point Mutation.
In Point mutations there is substitution of one base for another.
Example: TAT TGG CTA
TAC TGG CTA
The TAT changes to TAC which shows point mutation.
4. Yes. The point mutation have an effect on the outcome compared to the normal sequence.
When there is a change in one base of the gene it results into causing disease such as cancer, sickle cell anemia.
Answer: B. Water molecules slow down until they begin to bond together.
Explanation: When water is cooled, energy is removed from the system, and the molecules begin to slow down. When the molecules have slowed suciently, their collisions are no longer energetic enough to overcome their electrostatic attraction, and they begin to bond together. The other answer choices are inaccurate. Since ice is less dense than water, high pressure compresses the ice and actually causes it to melt. (Compression has no effect on water volume.) Cooling has no effect on the shape of individual water molecules.
<h2>Savanna & tropical rainforest</h2>
Explanation:
- Savanna is a grassland biome which is found South America .it is a type of natural biome which is changes during seasonal pattern for examples- elephants,cheetahs, wildebeest
- It is here and there found in mild atmospheres, for the most part in zones that are transitional zones among grassland and forests.
- Tropical rainforests are forests in the tropics that get more than 100 crawls of precipitation every year.
- This unbelievable species extravagance is expected to a great extent to the blend of a tropical atmosphere and high, all year precipitation, which gives ideal developing conditions to the biggest number of plant species.
- The warm, wet conditions in the tropical rainforest cause quick disintegration of any waste, and on the grounds that daylight and water are abundant, any supplements discharged into the dirt are quickly utilized by the quickly developing vegetation, leaving the dirt incredibly poor thinking about the high efficiency of the biome as long as the backwoods stays flawless, supplements will rapidly burn through the environment.
