The polar head of a phospholipid is made of phosphate. The polar head has a negative charge that is made up of phosphate molecules. This polar region attracts water and is positioned outward to interact with the water.

Advantages of using solar energy are pollution-free, noise-free, on installation it produces free energy, clean and renewable. Disadvantages include high cost, energy dependent on sunlight exposure, power stations are expensive to build and devices powered by solar energy cannot be used at night
Answer:
Other cells.
Explanation:
All cells come from other cells as cells are "produced" when a cell divides into two.
Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.
