Osmosis: movement of water molecules from an area of higher concentration to an area of lower concentration through a semipermeable membrane.
Osmosis calculations: equation is π=iMRT
π is not equal to 3.14159 in this situation. π stands for the osmotic pressure and is usually expressed in the pressure unit of atmospheres.
Diffusion: the random movement of molecules from an area of higher concentration of those molecules to an area of lower concentration.
Prokaryotic cells: unicellular organisms that lack organelles or other internal membrane-bound structures.
Eukaryotic cells: organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes.
Mitosis: cell division in which the nucleus divides into two nuclei containing the same number of chromosomes with an end result of two identical cells.
Stem cells: an undifferentiated cell that is capable of dividing and giving rise to one or more distinct types of specialized cells.
Answer:
1) Stirring and pulverizing the soil before seeds are planted or removed as well as to loosen the soil in order to allow enough air into the soil.
2) Vitamin A, zinc supplementation and exclusive breastfeeding
3)Manure from horses, cows or cattle
4) Mechanical
Explanation:
A cultivator is a farm implement used for stirring and pulverizing the soil before seeds are planted or removed as well as to loosen the soil in order to allow enough air into the soil. This enables the crop to grow quicker. It is driven by a tractor and does more work than the harrow which is not tractor driven.
Nutrition-specific intervention is a programme by UNICEF to talk undernutrition in foetus as well as growing children. The nutrients specified are exclusive breastfeeding, vitamin A and zinc supplementation.
Manure is referred to as major component used to aid crop growth. It contains essential nutrients which are required by crops for growth and good health. Manure is natural and can be gotten from animal dung.
Seed drills are sowing machines used to sow seeds accurately at the precise depth and distance measured. It does an extra work of covering the soil as well as protecting the seeds from birds. Due to the fact that it is a machine, it saves time and labour as well as money.
An example would be the coral and the clownfish
old stone age could be the answer you’re looking for :))
Eukaryote cells are single I’m pretty sure like it’s 1 thing
