The coleoptiles which tips were removed will be short and straight while coleoptiles which were cut with the tips separated by mica will be short and straight. Ceoptiles which were cut tips and separated by agar they will be tall and straight.
The set of coleoptiles which will be left in the darkness for 24 hours will be tall and bent. While the set which is in the direction of light for 24 hours will be tall and bent.
Observation is that coleoptile will grow straight if the chemical was evenly distributed and curved away from block side as if growing towards the light because dark side has the higher concentration of auxin.
Answer:
A polymer is a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together
Synthetic Polymers: nylon, polyethylene, polyester, Teflon, and epoxy.
Natural Polymers: silk, wool, DNA, cellulose and proteins
Explanation:
Protons and neutrons are subatomic particles found in the atom of any substance.
These particles collectively determines the mass number of the atom.
- Protons are positively charged particles found in the nucleus of an atom.
- Neutrons do not carry any charges and are also found in the nucleus.
- Electrons are negatively charged particles.
Electrons occupy the extranuclear space of an atom.
Answer:
double fertilization
Explanation:
Flowering plants or angiosperms are seed-producing plants with the ability to produce reproductive organs-flowers and fruits with seed in it (unlike gimnosperms which contain naked seed). Another distinctive feature of angiosperms is their reduced gametophytes. This feature most likely reduces the time between pollination and fertilization. Fertilization in flowerin plants is double, meaning that two sperm cells fertilize ovule cells(egg cell and central nuclei cell): one forms diploid zygote which will develop in embryo, while other form triploid cell which will develop into endosperm (provides nutrition for the embryo).
