Answer:

The correct answer would be D) translocation.

Chromosomal translocation refers to the rearrangement or exchange of part of non-homologous chromosomes.

It can be of two types:

Balanced: It is an even exchange in which genetic information is neither lost or gained and genes are usually fully functional.

Unbalanced: It is an unequal exchange of materials during which some part of a chromosome may get lost or gained due to which function of a gene may get lost.

It can cause various diseases such as cancer especially leukemia and lymphoma, infertility, XX male syndrome et cetera.

4. Is being struck by lightning always fatal? What are a person's chances of surviving?​
Mrrafil [7]

Although it's rare, with the odds of getting struck in your lifetime being roughly 1 in 12,000, every now and then a human will provide an attractive target for lightning bolts to unleash their power. And of the roughly 500 people who are struck by lightning each year, about 90 percent survive.

Which of the following does not explain why if two people are exposed to the same high stress causing conditions, there is a lik
e-lub [12.9K]

Answer:

Probably B

Explanation:

They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct. Sorry I couldn't be more helpful, I'm only here because I searched for the answer myself. Good luck.

For each region of the lac operon on the F' plasmid, I+ P+ Oc Z− Y+ , determine whether the region is wild type (that is, it pro
UNO [17]

Answer:

A,B and E

Explanation:

  • I+: I refers to the lac repressor, the + indicates that the repressor is functional
  • P+:  P refers to the promoter region and the + indicates that the promoter is functional
  • Oc:  O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.
  • Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional
  • Y+:  Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional

So based on the breakdown above:

  • A is true because P+.
  • B is true because I+.
  • C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on)  which is not the correct form.
  • D is not true because Z-, no β-galactosidase is produced.
  • E is true because Y+.

Only A, B and E apply.

2. A hypothesis is an educated guess based upon observation. It is an explanation of a single event based upon what is observed.
uranmaximum [27]

A law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.

<h3>What exactly is a hypothesis?</h3>

A hypothesis is a guess based on a large amount of background information. If only five trees survived, they may have received more light than the other five.

In that case, one will devise an experiment in which the same plant is randomly assigned to different treatment groups with varying degrees of light, and the rate of growth of each group is compared.

Thus, a law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.
