Answer: Water has unique properties that makes it an amazing substance. The cohesive forces are the intermolecular forces (hygrogen bonding and Van der Waals forces) which develops the tendency of that resists the liquids to separate.
As a result of this the water molecules forms droplets. These bonds lies in the molecules of the same substances.
Example rain droplets rather than a fine mist, water forms droplets.
Answer: For three traits inherited in a dominant/recessive pattern, the probability of an offspring in a trihybrid cross between parents heterozygous for all three traits to be recessive at exactly two of the three loci is 23/64.
Explanation: Let A, B and C represent the dominant alleles and a, b and c represent the recessive alleles. The genotype of each of the parent will be AaBbCc since it has been said to be heterozygous for all the three traits. There are eight (8) possible different types of gametes from each of the genotype. This can be calculated using 2^n where n is the number of heterozygous loci.
The number of heterozygous loci in the genotype AaBbCc is three (3). 2^3 = 8. The gametes are;
ABC
ABc
AbC
Abc
aBC
aBc
abC and
abc.
Therefore, sixty-four possible offsprings are expected from the cross AaBbCc x AaBbCc.
Out of these offsprings, twenty-three (23) are expected to be heterozygous at two loci as boldly shown in the attached image.

Answer:
Fluid mosaic is what people consider the cell membrane to be. This is because of how the cell membrane works, its made up of various different molecules floating all over the membrane. The molecules are going in a fluid flow. For example ice floating in an ocean. Or oil floating on water.
1. The golgi apparatus is a membrane bound organelle found in most cells. It is responsible for packaging proteins into vesicles prior to secretion and therefore plays a key role in the secretory pathway.

3. A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

5. A vacuole is a small cavity or space in the tissues of an organism containing air or fluid, or a cavity or vesicle in the cytoplasm of a cell usually containing fluid
6. Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. Especially in protozoa, vacuoles are cytoplasmic organs (organelles), performing functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.
7. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.
