What are the similarities and differences between prokaryotic and eukaryotic cells?
Gelneren [198K]

Eukaryotic

  • Have membrane bound organelles, such as  a nucleus
  • Have multiple chromosomes
  • Usually multicellular
  • Animals and Plants
  • Have a mitochondria, endoplasmic reticulum, cytoskeleton, vesicles, larger ribosomes, golgi apparatus, vacuoles, cell wall, and a flagella
  • Eukaryotes are bigger than prokaryotes.

Prokaryotic

  • Does not have a nucleus
  • Has one chromosome (not a true chromosome, plasmid.)
  • Usually unicellular
  • Bacteria and Archaea
  • Contains smaller ribosomes, vesicles, flagella, cell wall, and vacuoles.
  • Prokaryotes are smaller than eukaryotes

Hope this helps :)

A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number
Mnenie [13.5K]

Answer:

The correct answer is - option D. 1/2

Explanation:

Extra digits on hands and feet mean an individual has six fingers in each hand and feet, this is known as polydactyly. Polydactyly shows an autosomal dominant type of inheritance pattern.

In this case, the mother is normal so she must be recessive alleles and the first daughter is normal so the father must have a recessive allele which means he is heterozygous.

Cross:

Man = Dd

Woman = dd

Their children :

    D      d

d   Dd    dd  

d  Dd    dd

Probability of polydactyl child = 2/4 or 1/2 or 50%

Rasek [7]

As most microbes reproduce asexually, "species" are defined by differences in their DNA sequences. when the genome of soil microbe a is analyzed, long stretches of genes from multiple species of other soil microbial species are discovered. This indicates that the microbes present in the soil underwent transformation and transfection. Transformation, shown in the image, is the process of the prokaryotic nucleus taking up the foreign DNA from other microbes present in the environment. Tranfection is like transformation but for the eukaryotic cells.
