A light microscope uses focused light and lenses to magnify an object. Light microscopes come in several forms. (1) Simple light microscopes use a single lens to magnify an object and cannot reach high magnification just like a handheld lens whose highest clear magnification in the best conditions is 25x. (2) Compound light microscopes use two sets of lenses - an objective lens and an eye piece. This is the type of light microscope whose magnification power reaches between 1000x and 2000x.
I hope this helps!!!
Answer:
Plants alternate their generations between sporophyte and gametophyte generations.
Explanation:
Plants life cycle has two generations i. e. Sporophyte and gametophyte. Sporophyte is the first phase of plant life cycle in which spores are produced that are diploid i. e. double number of chromosomes while the second phase is gametophyte in which gametes are produced that are haploid i. e. half number of chromosome. Gametes contains sperm cells and egg cells which fuse together in the process of fertilization.
Cations, lose
Explanation:
Positive ions are cations and they result when an atom lose electrons.
An atom is made up of subatomic particles:
- Protons are positively charged particle in the nucleus of the atom
- Neutrons carry no charges and they share the nucleus with protons.
- The electrons are negatively charged.
- When an atom loses an electron, it becomes a positive ion because the number of protons is now more than the number of electrons.
- An anion forms in a reverse way.
