Answer:
Independent assortment produce new combinations of alleles.
Explanation:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.
Multi cellular organisms are composed of many cells whereas unicellular organisms are composed of single cell. Multicellularity is indeed a progressive attribute of evolution where cells form tissue which forms organ and then organ system and finally an organism. Both multi cellular and unicellular organisms has advantages and disadvantages of their own. One of the main disadvantage of multi cellular organisms is that due to such a complex composition and functioning they require a large amount of energy for their maintenance and survival. Different organs and system require a huge amount of energy when it comes to comparison with unicellular organisms. A large amount of energy is also wasted in all these life processes. Though multi cellular organisms can survive in a variety of environmental conditions but then also their survival is difficult than any unicellular organism.
Answer:
Isotonic
Explanation:
A solution is isotonic to a cell if it has the same Concentration of dissolved particles as the cell. Water molecules move in and out of the cell at equal rate, so the cell size remains the same.
Answer:
1. 62 percent water, 16 percent fat, 16 percent protein, 6 percent minerals, and less than 1 percent carbohydrate, along with very small amounts of vitamins and other miscellaneous substances.
2. Food.
3. Catabolic, Anabolic, Metabolism
So the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set
