Prokaryotes and eukaryotes differ in the presence of the nucleus and the organelles. Prokaryotes are small in size and can easily reproduce and adapt.
What are prokaryotes?Prokaryotes are primitive simple cells that are characterized by single cells with no distinct nucleus and membrane-bounded organelles. Cyanobacteria and bacteria are examples of prokaryotes.
The simple structure of the prokaryotes makes them adapt to environmental changes faster than the complex eukaryotic cell. They have a quick reproduction rate and short life cycles, unlike plants and animals.
The simple and small system of the prokaryotic cell allows the movement and diffusion of the ions and molecules easily. They are extremophiles and can survive harsh environments.
Therefore, small and simple prokaryotic cells are advantageous over eukaryotic cells.

A trait I which the alleles are not dominant over one another
Answer:
They are co-dominance and incomplete dominance.
Explanation:
Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.
Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.

Explanation:
the diagrams represent a rabbit and an owl. rabbits eat only plants and typically feed during the day in open areas such as fields and meadows. owls eat only rabbits and other small animals and hunt mainly at night. identify one physical adaptation represented in the diagram that helps the rabbit survive in its environment. describe how this adaptation helps the rabbit to survive. (1) physical adaptation and (2) description.
The physical adaptations in rabbits include long ears and strong hind legs. These adaptations help rabbits to survive by enabling them to detect and avoid predators, find food, and reproduce successfully.
What is physical adaptation?Physical adaptations are characteristics that an organism has that help it to survive and thrive in its environment. These adaptations can be structural, physiological, or behavioral and can vary widely depending on the specific organism and the environment in which it lives.
Some examples of physical adaptations in rabbits might include their long ears, which help them to hear predators, or their strong hind legs, which help them to run quickly to escape danger. These adaptations help rabbits to survive by enabling them to detect and avoid predators, find food, and reproduce successfully.

ACTIVITY 2: BIKINI BOTTOM GENETICS INSTRUCTIONS: PART A: Smiley Face Traits (1) Get two coins and mark one coin with a "F" and the other with a "M" to represent each of the parents. The parents are heterozygous for all the Smiley Face traits. (2) Flip the coins for parent for each trait. If the coin lands with heads up, it represents a dominant allele. A coin that lands tails up indicate a recessive allele. Record the result for each person by circling the correct letter. Use the results and the Smiley Face Traits page to determine the genotype and phenotype for each trait.
Answer:
Mark one coin with an "F" and the other with an "M" to represent each of the parents. The parents are heterozygous for all the Smiley Face traits.

Germination can not be observed here, but if it is a monogenic trait controlled by complete dominance, then the genotype can be homo-zygous (e.g., AA) or heterozygous (e.g., Aa).
What is a dominant trait?In genetics, dominance refers to the phenomenon where one allele completely masks the expression of another allele (the recessive allele) in heterozygous individuals.
In this case, the genetic cross might be Parental 1 (AA) x Parental 2 (Aa) >> Filial 1 F1 1/2 AA + 1/2 Aa.
In conclusion, germination can not be observed here, but if it is a monogenic trait controlled by complete dominance, then the genotype can be homo-zygous (e.g., AA) or heterozygous (e.g., Aa).

in step 1 of protein synthesis describe two of the differences between the DNA template and its complementary RNA molecule
Answer:Proteins are synthesised (made) by the ribosomes using messenger RNA transcribed from DNA in the nucleus.
Explanation:
In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled. The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.
