The right option is; do not pass between the marker and the shore.

A white marker with black vertical stripes is a non-lateral marker which serves as navigational aids that give information and guide the vessel operators along the water areas. A white marker with black vertical stripes signal or indicate an obstruction to navigation. When a vessel operator sees a white marker with black vertical stripes, he should not pass between the marker and the shore.

A cubit is an ancient measurement that measures length

the problem with using cubits is that the size may vary so it isn’t precise

the benefits of standardizing measurement is that they are precise and do not vary unlike the cubits

A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr
Mariulka [41]
The correct answer is 50%, or 1/2. We know that round seeds are dominant, since the round pea plant has a genotype of Rr and the wrinkled pea plant has a genotype of rr. If it helps, draw a Punnett square with the two genotypes.

   R  r
r
r

The square works exactly like a coordinate grid. Combine the letters above and beside whichever of the four spaces you chose to find the genotype for that space.

   R  r
r Rr  rr
r Rr  rr

Therefore, 2 out of 4 of the pea plants have round seeds, since a genotype of Rr means that a plant will have round seeds, and 2 out of 4 will have wrinkled seeds, since a genotype of rr means that a plant will have wrinkled seeds. 2/4 simplifies to 1/2, or 50%. Therefore, there is a 50% chance that the offspring will have wrinkled seeds.

Hope this helps!

Answer:

The difference between Prokaryotic cell and Eukaryotic cell are;

\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or}    & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \  membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}

Explanation:

Prokaryotic cells

The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells

Eukaryotic cells

Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell
