Light microscopes can be used to observe any type of object, but using an electron microscope to look at metallic objects would damage the microscope.
Light microscopes can be used to observe live specimens, but preparing a specimen for electron microscopy would kill it.
Light microscopes have much higher magnification power than electron microscopes, as long as a high resolution image is not needed.
The correct answer is the root Cap
Answer: Meiosis produces the sex cells, that is the gametes (sperm cells and eggs) that unite to form a zygote. Meiosis ensures that the gametes have have haploid chromosomes so that the resulting zygote from their fusion will have diploid chromosomes.
Explanation: Meiosis is a type of cell division in which a cell divides twice to produce four daughter cells each with the half the number of chromosomes as the parent cell. Without meiosis new gametes are not produced. Meiosis ensures that the chromosomes are evenly distributed among the daughter cells and that each daughter cell contains 23 chromosomes. A sperm cell with 23 chromosomes fuses with an egg with 23 chromosomes to form a zygote with 46 chromosomes. If meiosis does not occur, gametes with haploid chromosomes will not be produced, and if the gametes have diploid chromosomes because meiosis does not occur, sexual reproduction will be a disaster because when two diploid gametes fuse the resulting zygote with be abnormal.
Answer:
A. Water
Explanation:
Sunlight is absorbed from above through the leaves
Carbon dioxide is absorbed from the air by the leaves
Oxygen is a byproduct of photosynthesis and is released by the plant from the leaves back into the environment.
The first is incorrect because the more massive an object, the more gravitational force acts on it.
The second is false because the gravitational force decreases with distance. It's why the outer planets are usually smaller.
The third is true. It depends on both mass and distance and attracts two objects together.
The fourth is false because temperature and pressure have nothing to do with gravity.
