Answer:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.
Answer:
8
Explanation:
Hydrogen has 1 Valence electron, and H2O has 2 Hydrogen. Oxygen has 6 Valence electrons so do 2+6 = 8. 8 Valence electrons! (Or one full shell not consisting of the first shell.)
The similarities are;
- Both of them depend on light to function
- Both of them could be adjusted during studies
- The object could be magnified or diminished during study.
<h3>What is SI V-Scope?</h3>
The SI V-Scope is a sort of a virtual microscope that is designed to operate in a manner that is similar to that of the compound light microscope. The both tools could be used for investigation.
Recall that a microscope is a device that could be used to see a very small specimen. The first microscope was the compound microscope and was invented by Robert Hooke. This microscope was used to observe the cells of cork.
The following are the similarities between compound light microscope and SI V-Scope;
Both of them depend on light to function
Both of them could be adjusted during studies
The object could be magnified or diminished during study.

Answer: Although both are X-linked recessive conditions, and therefore more likely in males, with the single X-chromosome. The recessive allele in colour blindness occurs at a higher frequency in the population and is a mild condition. Thus colour blindness does occur to a lesser extent in females because it needs the double recessive condition. DMD is a severe, disabling condition with a limited lifespan, and recessive allele frequency much lower, so the double recessive condition in females is very rare.
Explanation: DMD is an X-linked recessive, “nearly always in males” suggest that it also occurs due to a new mutation or some rare condition e.g. double recessive from an affected father and carrier mother, or inactivation of the normal gene in a heterozygote. It is also found that the defective allele is not completely recessive and that female carriers may exhibit mild to moderate effects.
colour blindness is polygenic, although the genes are all X-linked. It is more common in males than females. Females can carry two recessive alleles and so express the phenotype, but this is uncommon because the frequency of the recessive gene is low.
There are similarities in that both are X-linked recessives, therefore commonly expressed in males, who only have one X chromosome. The gene frequency of the colour blindness recessive is much higher than that of DMD, so the double recessive condition, which affects females, is more likely to be seen with colour blindness. In addition, DMD is a severe condition associated with disability and limited lifespan, which reduces the probability of mating between an affected male and carrier female
