DiKsa [7]
Options:
it has a cell wall but lacks a well–defined nucleus and organelles, and its cytoplasm doesn't have <span> much structure. - this is the correct one!


It contains a membrane–bound nucleus and organelles, and its organelles have specialized duties. </span>
<span>no!, this is false! prokaryotes don't have membrane-bound nucleus!

It contains a membrane–bound nucleus, a large central vacuole, a cell wall, a cell membrane, and chloroplasts. - no!, this is false! prokaryotes don't have membrane-bound nucleus!</span>


so, for this we only needed to know that prokaryotes DON'T have a membrane-bound nucleus (and this is also perhaps their most important property)

BlackZzzverrR [31]

Answer:

Probability that both cats described will have an offspring who is heterozygous for both traits is 50%, according to the scenario given.

Explanation:

When a cat amazing and bashful is crossed with a cat average and boring, it is a crossing where two traits are taken into account that will be segregated independently by the parents, and the result can be obtained by analyzing their genotypes and making the corresponding crossing in a Punnett square.

<u>Genotypes</u>:

  • <u>Male cat</u>  AABb
  • <u>Female cat </u> aabb

<u>Crossing</u> :

Punnett's square (simplified)

<em>Alelles       AB      Ab</em>

<em>ab            AaBb  Aabb</em>

<em>ab            AaBb  Aabb</em>

<u>Offspring</u>:

  • <em>AaBb amazing and bashful (heterozygous for two traits) 50%</em>
  • <em>Aabb amazing and boring (heterozygous for trait A ans homozygous recessive for B) 50%</em>

<u><em>Probability that they will have an offspring who is heterozygous for both traits is 50%.</em></u>
